only for the climate, but also in your building
For many buildings, heating and cooling the indoor climate
is a huge cost factor. For that reason alone, there is much to
be gained. The TripleAqua climate system enables you to
independently heat and cool different rooms as required, but
using up to 50% less energy. This makes it one of the most
efficient systems in the world. Aim: to bring your building to
energy label
+++
A
level!
High quality system, low water temperature
A heating system is, in fact, a huge energy consumer.
TripleAqua utilizes a heat pump combined with high
efficiency indoor units. Thanks to the system’s
unprecedented heat transfer, a much lower water
temperature suffices, with huge savings and minimal losses
as a result.
Smart storage and energy exchange
Cooling with a heat pump during the day creates waste
heat, while heating creates waste cold. Other systems reject
surplus energy immediately. What a waste! TripleAqua
exchanges this energy between rooms and passively stores
the surplus heat and cold and uses them for free heating
and cooling. This results in spectacular energy savings,
particularly during the spring and autumn.

3 Transport, storage, handling
and positioning
from the pallet, to be taken directly to its’ assigned space for
immediate installation.
It is the sole responsibility of the customer to provide the
protection necessary to prevent vandalism and weather
deterioration of the equipment. Under no condition should
the units be left unprotected from the elements. If the
equipment is not needed immediately at the job site, it
should be left in its shipping carton and stored in a clean, dry
area of the building or in a warehouse.
DO NOT place units in corrosive environments or in locations
subject to temperature or humidity extremes (e.g., attics,
garages, rooftops, etc.). Corrosive conditions and high
temperature or humidity can significantly reduce system
performance, reliability and overall life.
The equipment is NOT suitable for outdoor installations.
Before installing any of the system components, be sure
to examine each pipe, fitting and valve, and remove any
dirt or foreign material found in or on these components.
Manufacturer’s warranties are void if foreign material is
allowed to be deposited in the drain pan, valves, pipework,
or on the motor or fan wheels.
3.4 Lifting and Handling
Coils and some parts are sharp. Avoid touching these parts
while handling the unit.
Large units may be heavy. Move them with two persons.
Although TripleAqua is designed for durability and fabricated
with heavy gauge materials and have a robust appearance,
care must be taken to assure that no undue force is applied
to the casework, coil, piping, drain connection or other
components such as control boards during handling.
Wherever possible, all units should be handled by the
cabinet, or as close as possible to the mounting points.
In the case of a fully exposed cabinet unit, the unit must
obviously be handled by the exterior casing. Gloves should
be worn when handling finished, painted units and should
never be set down on unclean, hard surfaces. There is a risk
of scratching the painted or finished surface.
3.5 Anchoring and positioning
Anchoring
In all cases, the steel structure of the unit needs anchoring.
Suitable holes (4 to 6 pcs) are foreseen at both sides and
suitable for this purpose.
Sufficient clearance must be provided for service and
removal of the parts. See 5.2 drawings.
3.1 Transportation
TripleAqua units are supplied fully assembled and tested
(except for accessories supplied loose). They are ready to be
installed, commissioned and operated in the field.
3.2 Storage
If, on site, the unit must be stored out of operation, before
commissioning, the installer is to follow the following
precautions to prevent frost, damage, corrosion and/ or
deterioration:
• Keep the unit packed in the box as long as possible
• Check if all openings, such as for electrics and water
connections, are plugged and sealed.
• Never store the unit where temperature may rise
above 50 °C
• Minimum storage temperature is -25 °C, only if the unit
is properly drained, no water inside
• It is recommended to leave the finned coils covered
with the transportation cover to protect them against
any risk of damage which is likely to occur on
construction sites.
• Never use steam to clean the unit.
• Check the unit on a regular basis for visual damage
• Remove the tools required to access all the panels
and secure them well on site.
3.3 Receiving and Inspecting
Directly upon receipt, the INSTALLER shall immediately
inspect the unit for any damage since it has been delivered
ex works and transported at the customer’s risk. Also, check
if all the goods and parts have arrived as specified on the
delivery note. Check all goods carefully. Damage should
be reported immediately (within 4 hours) in writing to the
carrier and the distributor. Even if the damage is only on the
surface or box, please notify the local TripleAqua dealer as
well.
The manufacturer disclaims all responsibility for the
shipment even if it has organized the transport.
All units are carefully inspected at the factory throughout the
entire fabrication and assembly processes. All components
such as motors, coils, controls, valve packages and more,
are carefully tested for proper operation, visually inspected
and verified for full compliance with factory standards.
Operational testing for all components has been performed.
Units are usually shipped on pallets of up to 5 units. Single
units are packed in boxes. Each unit is factory tagged
according to the label. This allows the unit, upon removal
8
Filters can be removed from the back or bottom on
horizontal mounted units and from the front on vertically
mounted units. Do not handle unit by coil- or piping
connections as damage may occur. Anchoring the
equipment in place is accomplished by using the mounting
points provided, and positioning the unit on a LEVEL
horizontal plane. The positioning is correct if the drain pan
is pitched horizontally to provide proper drainage when the
unit is installed level.
Units can be installed horizontally and vertically.
Units are designed to be bolted to the wall structure through
the slotted wall mounting holes in the chassis, used for
anchoring to pre-installed studs.
Fixing is provided with the identical mounting slots in the
top panels with hanging rod and field supplied rubber-inshear insulators. They can be used for proper suspension and
vibration isolation only in very critical applications.
The type of mounting device is a matter of choice, however
the mounting point should always be at the 4 to 6 points of
the cabinet.
Check that your lifting equipment can safely support the unit
assembly and component weights. See technical data for
unit weights.
All supports must be designed to meet applicable local
codes and ordinances. All fastening devices must be
designed to mechanically lock the assembly in place without
the capability of loosening or breaking away due to system
operation and vibration.
After mounting the unit, it is ready for the connections such
as water, drain and electrical.
3.6 About the Installation Site
When installing the unit, make sure that the
building structure and/or the supporting surface
can withstand the weight of the device. The
weights of the units are detailed in the technical data.
These units have been designed to be installed on the
floor, a wall or a ceiling. Normally rubber vibration damping
supports and internal flexible pipe work are not required.
When the unit is to be installed on the ground, provide for
a concrete supporting plate which shall assure a uniform
distribution of the weights. A special subbase / feet is
generally required.
When selecting the installation site, follow these guidelines:
• The unit must not be installed in the proximity of
open fire or greasy environments: the discharge of
boiler flue gases.
• The unit is installed level on an even surface
• The unit is not allowed to be installed near sources
of contaminated air, like chimneys or exhaust pipes
and the outlets of large-kitchen extractors. Grease might
build up on the fins of air exchangers and filter.
• Although the unit is extremely silent, the valves actuators
and fan(s) may generate a few dB(A) more sound than the
background noise level. In very sensitive situations,
please insulate the unit acoustically in the most
beneficial way.
• Contact an acoustical engineer for obtaining the
most beneficial acoustical results.
• The total experienced sound pressure level in a room is
greatly affected by the room merits.
• Never install in areas exposed to flooding or beneath
drip stones, etc.
• The installation site is suitable for the space required
for air circulation and for the performance of
maintenance operations

4.2 Drain pan
The condensate drip tray and the external connection are made of full stainless steel AISI 304
with outer insulation against condensation. In case of cleaning service, the drip tray is easy to
remove.
Due to a POSITIVE discharge pressure in the drain tray section, condensate water is additionally
driven away into the drain pipe. This positive pressure reassures that condensate water cannot
be staggered or sucked inside the drain tray. Also, the positive Pressure in the drain tray makes
it almost impossible that odours of the drain system can enter the TripleAqua unit. This design
is more costly, but avoiding contamination, cleaning, complicated service and hygienic issues
in the life time of the system matter too. Equipped as standard with close cellular expanded
synthetic insulation. The connection from the condensate tray to the external pipework is by a
strong ½”BSP thread. This solid connection avoids any leaks.
11
4.3 Ultra efficient EU5 / M5 air filter
Clean air means healthy air! The most important merit of indoor air quality is the
cleanliness. Air contamination consist of small particles that may reduce the wellbeing and health of humans. Unlike other dx-units and fan coils, this is why the
TripleAqua is equipped with special (M5 to EN779) ultra-efficient micro-filtration
cassettes filters, able to filter out these particles, polls and fine dust even as small as
5μ. (0.005mm) throughout the filter’s lifetime ensuring you clean air! Close pleats
ensure lowest energy consumption, an excessive large filter area and high efficiency and life span.
IMPORTANT
• Only the original filters will fit and
may be used.
• Filters cannot be cleaned.
• Filter material is enclosed by a stong,
water-resistant ABS casing.
• It is made of recyclable synthetic material.
• Filters must be replaced by original
TripleAqua spare parts.
Other types are not allowed.
• Used filters shall be disposed according
to local regulations, not in unsorted
municipal waste.
Filter replacement interval : The average usable time is 6 to 12 months. However, if
the white colour of the filter turns dark, please replace.
The filter use is always counted and checked by the controller, both in terms of
running hours as well as air volume filtered. When the FI:LT sign is shown shortly,
it is a pre-warning as it is about time to schedule a filter change soon. Meanwhile,
the unit may operate normally. Due to the extended 60mm thickness, long life and
convenient service intervals are possible. The filters can be replaced without any
tools. Clips on both side of the unit casing provide easy replacement, even in tight
surroundings. Filters come in four standard TripleAqua sizes, suitable to service all
models, limiting the number of service components. If the filter warning is ignored,
FI:LT is to be shown permanent and the unit capacity is reduced significantly, also
internal contamination will occur.

4.4 EC-fan
The Motor-Ventilator is a double suction, dynamically
balanced radial forward curved with direct driven controls.
Only available with the most efficient EC Motors, maintenance free bearings for long life. Unlike other fans using
plastics, our motor, the casing and the fan wheel is fully
made of strong metal parts. EC-Ventilators can operate stepless with intelligent electronics at the lowest possible speed.
It makes them up to 75% more economic than AC fans. Ultra
low speeds are the best choice in silent applications such
as hotels. Unit may operate even lower than the human ear
threshold value!
A remarkable feature is the intelligent Motor management.
Within the operational range and external pressure, the air
volume of the fan is kept constant, regardless the change
of external pressure or operating condition. The fan just
maintains the air volume as demanded by the 0-10 V signal!
This is an important move towards full thermal control of the
unit output.
An internal thermal overload protection is as standard. These
fans set the new standard in modern fan coil applications!
As a standard, these radial ultra-low noise and low speed EC
fan(s) with extra-large wheel diameter (146mm) and forward
bended shaped blades in full metal. The fans are double
balanced and coupled directly to a very energy efficient
DC single phase electric rotor motor with internal thermal
protection incorporated in version IP 44.
Fans are housed in a metal scroll casing, aerodynamically
shaped to increase aerodynamic efficiency and minimize
noise levels. The fans are produced in best European
factories. The efficiency is by far exceeding criteria as set in
the ErP2015 directive: Even at full power, the fan(s) used in
the TripleAqua consume less than 0,095kW!
Not sensitive to external pressure
Unlike other radial fans, the TripleAqua fans have full internal
compensation for change of external pressure, reassuring
the air volume delivered at the desired level as given by
the 0-10V controls. This feature enables the system to keep
the heat transfer performance independent of external
variations, such as filter contamination, external pressure
and unforeseen conditions. Having total control over
the air volume delivered is an essential to guarantee the
performance of the indoor unit in terms of capacity and
return temperature.
4.5 Room controller
Mostly, in a room, Room Controller(s) (RC) shall be mounted.
The wired RC model is known as 3RC866.
In large (open plan) rooms, more RC of this type may be
present. It facilitates the controls and the room temperature
is measured at more locations. Maximum 6 RC can be
connected to the local bus. Each RC has a local temperature
sensor. TripleAqua calculates the average temperature of all
sensors, which will become the average room temperature.

5.5 Corrections for glycol
All components placed outside in the central unit, are protected
against frost by applying insulation, frost resistant materials and
additional tracing on the heat exchangers. As option, tracing
on piping is available. Tanks and piping are frost resistant. Pipe
material is even resistant to fracture up to temperatures as low
as minus 30 degrees.
Water as a transport medium will be suitable, generally in all
European applications.
However, the use of ethylene glycol is a recommendation in
case of very cold Nordic climate operation (i.e. Scandinavia) as
frost inside the hydraulic unit components is likely to occur in
the hydraulic system at a winter stop due to power break down.
The addition of ethylene glycol will change the thermal and
physical properties of the water in a negative way and thus will
consequently reduce the unit performances. In case glycol is to
be used, please order the Nordic option N.
The Nordic option has lower pressure drop on the condenser
and stronger circulation pump to partially compensate the
performance loss.
The glycol percentage to be used can be obtained from the lowest operation conditions foreseen
and found in the table below. Also the multipliers are shown to obtain the changes of the unit performances according to the added percentages of ethylene glycol.

cf P 0,989 0,987 0,985 0,983 0,982
cf G = correction factor indicating the increase of the glycol&water flow to be circulated
cf w = correction factor indicating the increase of the pressure drops through the
condensor, evaporator and other components
cf Q = correction factor indicating the decrease of the cooling / heating capacity
fc P = correction factor indicating the decrease of the total absorbed power consumption
Note:
The units equipped with option N (Nordic) are mostly compensated for glycol losses thanks to
over-dimensioned condenser and circulation pump with added power and head. See option specs.
Check the table above to check the considerable differences between glycol and normal water,
regarding to performance, pressure drop and volume flow.
• When choosing ethylene glycol (e.g. Antifrogen N) or propylene glycol (e.g. Antifrogen
L), it should be considered that the physical properties of ethylene glycol offer more
benefits for the design and energy consumption of the system.
• However, Propylene glycol, which is food safe, must be used where the heat transfer
medium could come into contact with drinking water and/or food.
• The minimum proportion of ethylene glycol is 20% by volume and for propylene glycol,
25% by volume. This is essential as lower concentration leads to poor corrosion
protection, it even could contribute to corrosion.

6 Installation
The cold valves and piping should be kept thoroughly
insulated.
Operation on open loop (non closed systems) is not allowed.
Arrange drain points complete with plugs, clocks, etc. in the
proximity of the low points of the water lines.
Design the pipework with the minimum possible difference
of level. Automatic or manual vents need to be installed
inside on the high points of risers and water piping to allow
the outlet of the air in the circuit. Due to variations in water
temperature, the system is to be kept at the correct pressure
by means of an expansion tank or equivalent device.
All the pipework of the cold water piping must be insulated
with suitable vapour seal type diffusion proof insulation.
Thickness depending on local humidity. Consult your
insulation supplier. Insulation is essential to prevent the
condensation on the piping itself.
It is also advised to insulate the warm water piping, avoiding
transmission losses.
The weight of the water piping and connections must be
supported outside by additional brackets, external of the
unit. The connections of the unit itself are not able to support
any weight and shall not be stressed.
It is usually not necessary to put flexible couplings on the
water circuit.
A fine filter water, aerator and magnetic filter, although
not included in the supply, must always be fitted as part of
the plant components. Their installation is mandatory for
warranty. See section 6.6
Be very careful when applying water connections
to the indoor unit. You must use TWO wrenches
giving force in opposite clock and anti-clock wise
directions, to avoid any torque on the unit couplings.
If torque is applied, inner piping will be damaged!
Connect the water pipes with the attachments of the unit
whose diameters and positions are given in this manual.
Select piping at minimum a similar sizing or larger.
6 Installation
Mount the unit using the fixing slots on the unit and M8/10
drop rods or fixing bolts.
Attach the insulated ductwork to the spigots on the
discharge plenum (if applicable), and on the return plenum
(if applicable)
Original TripleAqua 3PL plenums will fit both on the
discharge side as well as on the return side.
IMPORTANT Keep in mind that if our standard plenum 3PLxx
is not used or if not all the spigots on our standard plenum
are connected to ductwork the performance of the unit will
be heavily compromised.
Pipework should be sized to keep water velocity from 0.50
(local) ~ to max 1 m/s (main pipes) to minimize water
noise and keep water pressure losses low, as this strongly
contributes to low pump energy consumption over the
life time of the system and to avoid water transportation
noise. Indoor units are extremely silent and the EC Pump is
designed for maximum energy savings. High water speeds
will obstruct these merits considerably.
Pipework should be fit for purpose and equipped with
oxygen barrier (plastic piping)
6.1 Hydraulic connections
Before installation, read the safety regulations in force on
the site and in particular for this machine, to obtain a safe
and exact design and proper installation. We recommend to
apply shut-off / interception ball valves in both supply and
return piping down and upstream to isolate the unit from
the site if needed. A water pressure gauge is suggested at
the return filling point to facilitate the operator checking the
system water pressure. This supports user routine control and
maintenance of the unit.
TripleAqua recommends to install a SpiroCombi on the
suction side towards the pump.
Flow switches are part of the internal system and are not
required externally.
Install on/off valves (accessory) on the lines at the inlet and
outlet of the main branches to be able to shut off pipework
sections in case of system layout changes.
Condensate protection for the chilled water valves and
piping must be provided by installer.
22
6 Installation
if all the water has been taken out of the coil, in example by
applying compressed air.
It is possible to use anti-freezing solutions (ex. Ethylene
Glycol) in the appropriate percentage (see chapter)
Even if the system is drained, unit coils may still hold enough
water to cause damage when exposed to temperatures
below freezing. It is hardly possible to remove all the water
by just turning the coil. Some coil sections will remain water
inside.
6.5 Cold / warm / return / condensate
water connections
All piping should be properly supported. Do not support
piping to unit valves or controls. Factory drip pan is preinstalled and suitable for a ½”O.D. BSP connection After the
connections are completed, the system should be tested for
leaks. The hydronic systems should be tested with water. Test
pressure at the outdoor unit must not exceed 6 barg.
Pressure testing should be completed prior to finishing
the construction site, tiles structure, carpet, finished floors,
painting, caulking, etc.

In the event that leaking or defective components are
discovered at the unit components, TripleAqua distributor
must be notified before any repairs are attempted. All leaks
should be repaired before proceeding with the installation.
6.2 Mounting Unit to wall / ceiling
For proper installation and operation, check each of the
followings before mounting the units:
Allow adequate space for the unit and free area for service
clearances.
h min

Remove the appliance from the point of installation, drill
the holes where marked on the wall and insert the screw
anchors. Place the appliance against the wall and fix it by
tightening the screws into the anchors. Carry out the water
and electrical connections as described in the relevant
paragraphs. To replace the housing, proceed according to
instructions given below.
6.3 Installation piping
The clearance between drain pan and ceiling should be
enough for drain line pitch with a minimum slope of 2/100.
Allow sufficient space for lifting ceiling tiles and unit access.
6.4 Frost protection
Danger of freezing:
If the unit and its water connection are subjected to
temperature lower than 0°C, some specific items will be
essential to avoid icing in the pipework. You need to verify

6 Installation
6.6 External Components
6.6.1 Expansion vessel.
The TripleAqua components are not equipped with an
expansion vessel. This item is to be added on site in the
suction line.
Calculate the expansion vessel according to the total system
size, with addition to the water volume externally in the
central unit(s). Capable to handle the full expansion of the
water content over the full temperature range. As a rule of
thumb, Expansion vessel size is 2 - 2 ½ % of the total water
system volume.
• A membrane expansion tank complete with a safety valve
and a drain facility is mandatory. which shall be visible
to inspection by the OPERATOR.
The expansion tank shall be dimensioned in such
a way that it can absorb a 2 - 2 ½ % expansion of
the total volume of the water in the plant
(exchanger, pipelines, uses and storage tanks, if available).
The expansion tank shall never be insulated when the
circulating fluid is not flowing through it. To be placed inside
near the unit suction.
Care should be taken to assure that no components in the
valve package are subjected to a high temperature which
can damage seals or other materials. The electric control
valves, are provided with a manual opening handle which
can be turned. These valves must be placed in the “open”
position during all connecting and filling operations.
In accordance with good soldering and brazing practices,
welded pipe connections must always be wrapped with
a wet rag to dissipate the heat. If the pipe connection is
made with a union, the unit side of the connection must
be prevented from torque forces causing twisting during
tightening to prevent damage to the coil unit tubing.
Over-tightening must be avoided to prevent distorting
the piping and components or joints, ultimately causing
a leak. All inlet and return connections are marked at the
appropriate spots with symbols and sticker / text. After
the quality of the pipe work integrity has been established,
piping should be insulated in accordance with the project
specifications. At all times, the cold inlet needs total
insulations avoiding condensation.
It is recommended, avoiding heat losses, to insulate the
warm inlet pipe too. This is the choice of the specifier or the
installer contractor.
Water Piping material
Piping should have a fit for purpose oxygen barrier layer.
Piping can be aluminium, (stainless) steel, copper, ABS,
Kryoclim, PE-Xa or PVC, but must comply with local codes
and suitable for closed loop water or water-glycol HVAC
systems.

6.6.3 Electric Bypass valves
The TripleAqua is a Variable Water Flow system. Due to ever
changing demands of the terminal units, water flow in the
cold and warm flow of the system may vary at all times
between virtually zero and full flow. The outdoor unit will
produce warm and/or cold water depending on a range of
settings, average ambient temperature, time of day, water
flow, set point lines, economic settings and more. In humid,
combined with lower ambient temperature conditions, the
outdoor air heat exchanger may operate as evaporator and
may build up frost. This needs to be defrosted when the
amount of frost has exceeded certain limits. The outdoor
unit may start a defrosting cycle automatically. In the
meantime, it will be likely, indoor terminal units will still be in
need of warm water. The thermal buffer in the outdoor unit
(optionally equipped with PCM) will reassure the delivery of
water during defrost. Heating operation of indoor units is not
disrupted.
However, it is not that likely that enough indoor units
are requiring cold water too. In order to perform a rapid
and efficient defrost cycle, the outdoor unit will activate
additionally internal water flow over the internal evaporator.
This flow needs to be thermally supported by external water
flow over all the three pipe lines. The installer is to place two
(normally closed) water valves located as specified, type and
Kv value as specified, with significant distance from the main
unit. These two valves are activated during defrost only, and
will reassure flow in the piping system. As a result, the defrost
cycle can be performed and terminated in just a couple of
minutes. The two valves are commanded and energized by
the central unit. over a 230V command wiring. The table
below specifies the valves to be used and the water content
to be activated during a defrost cycle in the pipework.
6.6.2 Water Filter
Water filter and deaerator
Air (oxygen) and dirt in system water are causes of
disruption. They cause wear, damage to system components,
process disruptions or even failure. TripleAqua recommends
to install a SpiroCombi deaerator & dirt separator to reduce
these risks to a minimum. This device will remove air bubbles
very effectively out of the system and has in built filter for
dust particles. In addition, a magnet with a smart cleaning
tool picks up metal parts before they may enter the EC Pump
(having permanent magnets…). The Spiro Combi shall be
installed inside the building, centrally in the return pipe work
at the suction side of the system.
26
6 Installation
6.8 Ductwork connections
All ductwork and or supply and return grilles should
be installed in accordance with the project plans and
specifications, and local codes. All supply and return grilles
should be provided as recommended in the engineering
manual and plenums: use the full number of supplied
spigots.
Suction noise transmission will be reduced with loose
return air grilles located as far as possible from the unit.
Alternatively, an acoustical suction duct section will provide
attenuation too. See ENGINEERING MANUAL chapter 17.
TripleAqua may provide plenums for return and/or supply
air. The original 3PL and 3PD PLENUM models will fit both on
return and supply.
NOTE: TripleAqua strongly recommends to use ALL
plenum connections. Blocking some off will compromise
the unit performance, sound and thermal outputs in a
negative way.
Supply connections for 3PL plenums are 203mm ID flexible,
thermally and acoustically flexible or solid duct work.
Avoid any strong bends or squeezing of duct work as this
has a considerable negative impact on noise and pressure
drop. Return connections are 203mm ID flexible, (optional
acoustical) flexible or solid duct work. Avoid any strong
bends or squeezing of duct work as this has a considerable
negative impact on noise and pressure drop.
Plenum models are designed to be connected to ductwork
with a restricted amount of external static pressure. Consult
the fan graphs in the engineering manual for unit external
static pressure limitations. Units provided with outside air
should have some form of low temperature protection to
prevent coil(s) from freezing. This protection may be a lowtemperature thermostat to close the outside air damper, a
heat reclaim system, a preheat coil to temper the outside
air before it reaches the unit, a local damper, or any other
protective method, optionally controlled by the unit itself. It
should be noted that none of these methods will adequately
protect a coil in the event of power failure and frost. The
best method of frost protection is to use glycol in the proper
percent solution for the coldest expected air temperature.
exceed the external static pressure rating of the unit: see the
fan graphs.
6.6.4 Optional Pre-set bypass valves
If the system should operate in extreme low capacity, the
compressors will likely not operate and the buffer tanks
will take over delivery of warm and/or cold supply water.
Likely, water flows will be extremely low or even zero. In
this situation, for large systems, it may take more than 10
min before warm or cold water will arrive at a terminal unit,
located far away. The installer may choose to install a small
bypass to avoid water flow coming to a full standstill, thus
increasing time responses to climate requests. However, it
should be noted this bypass creates a minor thermal loss.
6.7 Condensate drainage
The drain pan condensate connection is a ½” inch male pipe
thread fitting. Elevate the unit so the condensate lines are
pitched at least 20 mm per meter. In some cases it may be
necessary to insulate the condensate near the unit with
insulation to prevent water from condensing on the outside
of the pipe. In some climates or locations it may be necessary
to protect trap from freezing in the winter. Connect a ½”ID
BSP connector over the stainless steel outlet of the drain pan.
This should be a mechanical connection that allows easy
removal of the drain pan when servicing the condensate
piping. Take precautions the connector thread shall not leak
by applying a proper seal. Do not torque the connector.
The condensate drain should always be connected and
piped to an acceptable drainage disposal point. For proper
condensate flow, the drain piping should be sloped at all
points away from the unit at the given 20mm per meter. A
odor trap must be supplied to ensure proper drainage and
odor containment. Condensate drain lines should be at least
the same diameter as the drain connection.
Provide points to flush and clean the drainage system.
The drain lines should be supported every 1- 1½ m to
prevent bends causing staggered drain water. Make sure the
drain line is free of kinks and obstructions .

6.9 Mounting the remote controller
The TripleAqua remote controller 3RC866 are designed to be fitted on 1.5 m height from the floor,
free accessible, not limited or exposed to internal or external heat sources, not on an outside wall.
For large rooms, a max of 6 remote controllers may be connected. This will facilitate the controls
and all temperature sensors of these remote controllers will calculate an average room controller
temperature together.
Mount the room thermostat(s) at a location where the actual room temperature can be determined
correctly. Avoid influences by objects, draft, transmission, radiation, sun light or internal heat sources.

7.2 Warnings
All field wiring connecting should be in accordance with
the national standards and applicable local codes. All unitmounted components and electrical heater elements, if
ordered as a factory option, are factory wired to the control
box. Remote-mounted control components are shipped
loose for field installation and are to be wired in strict
accordance with the wiring diagram and the TripleAqua
controls manual.
Connections should be checked prior to start-up to ensure
connections have not come loose during shipment or
installation, minimizing problems during commissioning.
Check the hydraulic diagram for the indicated bypass valves
as required to guarantee proper defrost operation.
Field power supply wiring should be fed through end pocket
openings (rubber grummets) in the supplied junction boxes.
Any modification of the unit wiring without factory
permission will void the warranty TripleAqua assumes no
responsibility for any damages and/or injuries from improper
field installation and/or wiring.
Field electrical power connections are made in the electrical
box, which is mounted to the side of the chassis opposite
the primary coil piping connections. Most connections are
made by removable Phoenix connectors. Please observe the
diagram and the different unique colors of the connections,
avoiding mixing of connectors.
Low voltage wires should be brought separate into the box.
NOTE: Wiring coming through the wall should be sealed to
stop cold air infiltration through the wall cavity, which could
affect Remote Controller sensor operation.
Wiring coming through the floor should be sealed too.

7.5.1 Detailed optional connections
Input D1 comfort or eco (occupancy / ving)
The input is intended for the following command functions:
( symbol goes from on to off )
• Responding to a VING card operation for Hotels,
• Respond to an Occupancy detector in offices and
public rooms
• Respond to external wired command - voltage free input.
The delay time to instruct the controller to switch between
Comfort/Day and Night/Eco mode can be programmed by P75.
NOTE: ONLY Connect to the GATE D1 input for this function.
If P75 = 0 : This input is not active. Unit may follow clock function. D1 = NO (normally open)
Comfort to Night/Eco is given by the parameter P75.
From Night/Eco back to Day/Comfort, no time delay is needed.
If P75 > 0 : D1 => closed : Mode COMFORT => Mode ECO/Night with P75 min time delay
D1 => open : Mode Eco/Night => Mode COMFORT with no time delay
If the mode was standby, the mode does not change into Eco.
Input D1 dew point sensor
If P75 = -1 : D1 is meant for dew point sensor:
If D1 is closed: cooling valve is closed too.
The dew sensor will interrupt the cooling process until the D1 input is opened again.
7.5.2 Input D2 forced gate / commissioning / self test
Input D2 is used to force the unit in a special setting, to commission the system, purge/flush with
water and addressing, select the gate and start auto addressing. See the controls manual for addressing.
Commissioning:
Before any commissioning is started, at the factory, D2 is a closed contact, and no GATE or SAT is
assigned. When power is applied, after 5 min, a Self-test is completed.
NOW: BOTH WATER VALVES will open and remain open as long as D2 is closed.
This enables the installer to fill the system with water, circulate, flush and vent the system fully with
all indoor unit valves open. A relay Q3 will flash slowly to indicate this status. See also Controls manual chapter 7.2 COMMISSIONING.
Normal status for D2 after commissioning completed: open contact. Valves of indoor unit will close.

7.5.3 X6 external mode on / off or co2 level input
Input X6 can be used for an external digital input by a switch or relay.
It may alter the ON/OFF mode of the unit or operates as a CO2 sensor input.
NOTE: 24V DC is present on the input. The function for X6 is activated by parameter P76:
P76= 1 function is not active @ NO (default value) and is active when X6 is closed
P76= 0 function is not active @ NC and is active when X6 is opened.
P76 =2 function as an input for a CO2 level detector delivering an 0-10V signal.
External on/off
Set P76 to 0 or 1
The input is intended for an external wired command to change the MODE from On into OFF
An active input will force the unit into OFF: (On off symbol goes off )
Can be used for a Fire command or Open window contact
If GATE unit on a process bus face a change of mode through the X6 input, the same command is also transferred
and obeyed by SATELLITE units. So this switch, contact or detector must only be connected to GATE unit.
CO2 level input
Set P76 to 2.
X6 input is able to measure the CO2 level which can be used to adjust a fan or a
damper to control the fresh air valve at output Q1. The CO2 set point level to act
is pre-set in a P15 parameter. The CO2 level can be read in P45 (Gate only). If the
detected value is higher as pre-set, the output is active. The Sensor range of the
CO2 level to be connected shall be 0-2000 ppm corresponding to 0-10 Volts.
7.5.4 Output Q1
REMOTE INDICATON - EXT. COMFORT MODE DETECTION / FRESH AIR / CO2
CONTROL
Output Q1 is a voltage free SPDT Change over contact. It can be used to detect if
unit is ON in Day-Comfort Mode or to control (open/close) an external open/close
servo motor for fresh air and/or return air damper.
If a CO2 measurement device is connected, the output can activate the damper
only according to CO2 ppm level.
P76=1: Output Q1 is made active and used to report externally if unit is on
and in COMFORT MODE.
P76=0: Output Q1 is made active and used to report externally if unit is
STANDBY or OFF

P76=2: Only to use if Input X6 is used for CO2 measuring. Q1 is only closed if P45 > P15.
P45 = measured level of CO2 in ppm
P15 = set point level of CO2 in ppm
Note: The CO2 sensor must be calibrated to 0-2000 ppm corresponding to 0-10Volts.
Output Q1 is also permanently activated during the SELF TEST.
Q1 MAX 230V AC @ 2A / 30V DC @ 3A. DO NOT OVERLOAD. NOT FUSED
7.5.5 Output DO2 extra booster fan / louver
Output DO2 is to be used to feed a (not supplied) relay to control an external fan.
Note: If an electric heater is present, the common voltage for DO1 and DO2 shall be
24V AC.
So a field supplied added RELAY 24VAC must be fitted too. See controls manual.
The output is active if the fan signal X5 is above P77-n . (for extra fan)
The output is active for a fan coil louver motor if the fan is on and P77-n = 1.
Not active if P77-n = 0.
7.5.6 Output Q3 alarm relay
Output Q3 is a voltage free SPDT NO contact used for reporting an alarm externally.
A parameter P59 will define if this output is: not active @ NO and active when NC or
reverse active @ NO. The output is active when an alarm is present.
If the alarm is reset, the output is not active.
P59 also instructs if filter alarms are included to the alarm output or not. See alarms
table.
Most alarms are automatic reset, the alarm disappears if the reason is no longer valid.
Alarms for fan(s) and electric heater are manual reset. Alter P01 from 0000 to 0001 to
reset these alarms.

7.5.7 Output Q4 internal or external
condensate pump
The output Q4 controls the optional condensate pump
using internal air detection sensors.
The unit will set the pump active and will close Q4 when ALL
these following conditions are met together:
• P73 > 0
• Unit is operating in cooling, automatic or in
dehumidifying mode.
• Unit has been in cooling or cooling request for more
than 3 min.
• Unit cold water inlet temperature B2 is below 22 °C
• The outlet air temperature is P73 degrees lower than
the return air temperature.
When (one of) these conditions are no longer valid,
the pump will stop after another 3 min of operation.
The pump is allowed to run dry but may consume 16 Watts.
See the 3FS controls manual to understand all wiring and
addressing details of the local CE+/CE- bus and the BMS
Building Management System bus.
7.5.8 HMI - Control Panel
For service, a Human Manual INterface (HMI) Model POL
895.50/STD as shown below can be connected to a GATE unit
and is to be used for service purposes. This will give access to
parameters P51 and up. Connect the HMI only to the GATE
unit T-HI connector.
7.5.9 Modbus / BacNet Building Management
Functions
The TripleAqua GATE controller exchanges information with
the other local SAT units and Room Controllers through the
local CE+/CE- bus that connects them internally in the same
room. This information is either sent to or received from the
superior BMS system. Therefore the GATE also acts as an
interface to this superior system. The fan coil controllers and
Room Controllers are for one room. Every GATE unit connects
these over the bus to a system with several rooms. Individual
room units may send their heating or cooling demands to a
primary plant and can receive operating mode, set-points,
air- and water temperature status, etc. from a superior
controlling system.
The Modbus RTU protocol applied is suitable for residential,
commercial and light industry environments.
NOTE: Only the GATE unit shall be directly connected to a
BMS system over the on board RS485 terminal connection.
Other SATELLITE units in the same room communicate their
relevant info through the local Process CE bus to and from
the GATE unit connected to the BMS. This principle saves a lot
of cabling and adresses.
ModBus RTU and limited BacNet MS/TP are on board as
standard. For other BMS platforms i.e. LON, M-Bus, KNX,
OPC, WebServer, BacNet Ethernet TCP/IP: select the POL
638.00/ STD, POL 636 or POL 908 converters . Ask your local
distributor for advice. The GATE receives external commands
for MODE, FUNCTION, CLOCK, SETPOINTS, FRESH AIR etc.
The GATE sends out status values, sensors, alarms, energy
data etc.

8.1 Preliminary checks
Never attempt to try to start the system when you have not
studied fully, and understood the operating instructions. You
need to carry out following pre-start checks:
• Check the chilled water circulation pumps, circulation
and pressure of units and all other equipment connected
correctly to the system.
• Confirm that all pipe securing fixing points are tight.
• Check if the electrical connections are completed and
safe.
• The start-up of the external heat pump must be executed
by a qualified refrigeration engineer only.
• Operating the unit is only possible when a sufficient flow
and thermal load is applied to the system and water is
circulating in the internal water heat exchangers and
external circuit.
• All set point adjustments and control tests must be
carried out before the unit is started up.
• Ensure that all safety devices are operational and that
no alarms are active.
The unit must be commissioned for the first
time by an ENGINEER suitably trained by the
TripleAqua distributor. Failure to meet this will
immediately void the warranty.
Before the operations will start, hydraulic and
electrical works have to be completed by the
INSTALLER.
Work carried out by the authorized ENGINEER for commissioning is limited to the start-up of the unit, and will
never include any other installation action or operation
on the plant, such as, for example, electrical and hydraulic connections etc.
• Check that the components of the external water circuit
(pump, user equipment, filters, power supply tank and
reservoir, if any) have been installed properly, and
according to the manufacturer’s instructions.
• Check the filling of the hydraulic circuits, and make sure
that the fluid circulation is correct, without any trace of
leaks and air bubbles. If you use ethylene glycol as
antifreeze, check that its percentage is correct (do not
exceed 40% glycol percentage).
• Check that the pumps have been circulating for at least
12 hours. Then, clean the SpiroCombi and filters on
the suction side of the pump(s).
• Check the liquid distribution network in such a way that
the flow rate is sufficient.
• Check that the water quality is up to the specifications.
• Check the pump settings.
• Check the controls manual for all the user settings,
building manager parameter settings and project
settings.
Although the units may operate with variable speed control, variable water flow controls and may be overruled by
external Building Management Systems, TripleAqua cannot
warranty proper operation when in conjunction with any
particular external control.
All EC fan-coil motors have internal thermal cutout. The
motors will be de-energized if the internal temperature of
a motor exceeds a maximum to protect the motors against
over-heating and burning out. The auto-reset function will
resume the motor operation when the internal temperature
of the motor has dropped.
8.2. Venting / Flushing / Pressurize
FILLING
Fill up the system to the calculated hydraulic working pressure with clean drinking water according to the VDI2035
(part 2 nr. 4) / EN 12828 standard, optionally added with
pre-mixed glycol mixture.
The water supply must be analyzed and of appropriate
quality, filtered, if needed with water treatment. Otherwise,
damage to the control devices, damage to the protection
of the tube and heat exchanger surface is likely to occur if
the fluid is polluted, fouling and deterioration of the pump
fittings will occur too.
Check that all filling valves and vent cocks are closed.
Check if the water side safety devices are installed. Check
these devices for proper function.
Ensure that water flow through the unit is not obstructed,
open all corresponding shut off valves!
Never fill up above the maximum allowed
pressures
• The max. outdoor unit water pressure is 6 barg.
If the outdoor unit is at lowest level, this is also the
maximum system pressure.
• The max. piping system water pressure is depending
on the materials used in site.
• The max. indoor unit water pressure is 10 barg.
The operational water pressure is depending on system hydraulic height, usually preferred is 2-4 bars, though pressure
should during operation always remain between 1-5 bars.
This value may vary per project.
38
8 Commisioning
NOTE:
Limited operating pressure
water at outdoor unit
Check the pressure in the expansion vessel according to the
calculated hydraulic working pressure.
Start and stop the circulation pump with intermediate
breaks to collect all the air and vent them off.
NOTE:
The pump should not operate when not filled up with water.
Flushing the water system
Flush the system regularly to drain off impurities which may
have entered the pipework during installation
Before filling the installation, remove any
impurity, such as sand, crushed stones and
welding scales, coating drops and any other
material which might damage the evaporator.
It is advisable to flush with disposable water bypassing the
exchanger to avoid clogging.
Control accurately the absence of leaks during the filling
phase. Purge air regularly at all points.
The water used to fill the circuit shall be
treated in such as way that the pH will have
the correct value.
VENTING
Vent the system on all vents located in the pipe work. Also
the outdoor unit has vents on top of both tanks and venting
points are located on top of the internal return header pipe
as well as two to three venting points in the compartment
between the plate heat exchangers and the internal tanks.
WARNING: If the outdoor unit is not properly vented, high
pressure problems on the water plate heat exchanger will
occur as air in the water condensor cannot escape. Proper
venting may take several attempts.
HINT: Venting of the hydraulic system and indoor unit heat
exchangers is advised with all indoor units control valves
both fully open, heating and cooling. This is achieved by
energizing all indoor units with power whilst input D2 remains closed, setting them in commissioning mode.
When water is first introduced into a coil, air is sometimes
trapped in the coil tubing. This trapped air has a tendency to
collect at the highest point in the coil.
Most models of coils can be vented manually at the return
header using a screw driver. Venting can also be carried out
according to the procedure in the controls Manual Indoor, section 5.1.2. By opening both valves of indoor units
mutually, maximum flow inside the small tubes of the coil
is generated, thus forcing the air out of the coil pipes into
the return. Therefore, a manual air vent procedure is often
not required at each coil installed inside on the coil return
header. When there remains to be air trapped in the coil, resulting in “bubbling” noises within the unit or no water flow,
follow the procedure as described to vent the coil according
to 5.1.2 and manually vent the coil at the return header.
8.3 Water balancing
TripleAqua does not require water balancing per unit as
all flow in operation may vary per second. This will save a
considerable amount of time in commissioning. However,
at 100% full load, in case all indoor and terminal units are
requiring their capacity, the distribution system, piping
network and circulation pump setting will benefit a proper
pump setting. The pump(s) need to be able to meet this
demand. Pump(s) are self-regulating, as well as the valves
of the indoor units. In order to adjust and set the maximum
pump power/pressure as proper as possible to the water
distribution pressure losses and system values, proceed as
follow:
Open all valves of terminal units.: Energize and CLOSE INPUTS D2 on all indoor units longer than 5 min
The system will set itself to maximum water flow in a few
minutes.
Check with an local flow meter, if sufficient water flow is
seen at the terminal units as far away as possible, having the
highest distribution pipework pressure loss of the system.
You now may want to alter the default PUMP setting
(70% / 7 Volt) to meet the required flow. See Controls
Manual.
A total knowledge of the hydronic system, including its
components and controls, is essential to correct water
commissioning of the system and should only be completed
by a qualified expert. The system must be complete, and all
components must be in operating condition before beginning the water commissioning procedures.
39
The actual balancing of any indoor unit is preset by the dials
in the control valves on every warm and cold valve kit. See
controls document and technical sheet for settings.
It is advised to install ball valves and water flow measuring
valves at main sections on both flow and the return pipes
in order to shut off sections of the hydraulic system for later
changes of the system and local repairs and verifying correct
water flow.
Once the proper system operation is established, the definite appropriate operating conditions such as flow rates and
pressure drops should be recorded for future reference.
During commissioning, poor operating conditions may
exist due to incorrect system pressures, resulting in noticeable water noise or undesired valve operation or lack of
flow. Once the total system is correct, these conditions will
not exist on properly designed systems. If any noticeable
water noise or undesired valve operation persist, recheck
the system for air that may not have been properly vented
during start-up.
8.4 Air balancing
In particular if the unit is connected to external grilles, TripleAqua strongly recommend to install the original 3PL and
3PD plenum boxes. Plenums can be installed on the suction
and on the discharge side. Please take good notice not to
exceed the maximum external pressure drops as is indicated
in the technical specs and the fan graphs.
If plenum boxes are used, TripleAqua strongly recommend
to use all round spigots. If some spigots are blocked, proper
operation and performance cannot be guaranteed.
Especially if the external duct runs are unequal, additional air
dampers should be considered at the shortest duct runs.
Suggested external nominal external pressure is 30-50 Pa.

Maintenance Contract
TripleAqua recommends a maintenance contract with your
local service agent which provides regular maintenance
of your installation by a specialist trained in servicing your
equipment.
Regular maintenance ensures that problems are avoided
and minimizes the possibility that malfunctions will occur.
It also ensures the maximum operating life and efficiency of
your equipment.
10.1 General requirements
Each indoor unit may have its own unique operating
environment and conditions which indicates a maintenance
schedule that may differ from other equipment on the
project. A maintenance schedule and an individual unit log
should be maintained. This schedule will help maximize the
performance and service life of each unit.
The air filter(s) is the main and only maintenance
replacement item. In addition, cleaning and checking is
needed. All fans and valve actuators have permanently
lubricated bearings so no further field lubrication is ever
required. Do not lubricate fans or motors.
If the motor/blower assembly ever may require more
extensive service, only decide to replace the fan with an
original spare part.
10.2 Planned maintenance
Service panels are provided to allow access.
Check fan wheel. Dirt and dust should not be allowed to
accumulate on the fan wheel or housing. Failure to keep
this part of the unit tidy may result in an unbalanced wheel
condition which can lead to a damaged fan wheel or motor.
The fan wheel and housing may be cleaned periodically
using a brush and vacuum cleaner, taking care not to bend
the fan blades and to remove any factory applied balancing
weights on the blower wheel blades.
Tighten any set screws that may have loosened due
to vibration. Any blower or motor that is not properly
maintained will not be covered under the manufacturer’s
warranty.
The air filter needs regular replacement. See 10.4
The controller counts the filter usage in running hours and
air quantity filtered. If a filter needs replacement, the remote
controller will show a warning.
The TripleAqua fan coil has an ultra-efficient air filter,
cleaning the air of dust and pollution. It is able to filter out
micro particles and polls as small as 5μ (0.005mm)!
The filter use is counted by the controller. When the FI:LT
sign is shown shortly, it is a warning as it is time to schedule
a filter change soon. Meanwhile, the unit may operate
normally. Replace the filter soon by a fresh and original
TripleAqua filter to guarantee clean air. The filters cannot be
cleaned. It is made of recyclable material. Dispose the filter
according to local regulations.
If the filter warning is ignored, FI:LT is to be shown
permanent and the unit capacity is reduced significant.
After a preset number of revolutions in P41, the unit send
out a filter replacement request pre-warning text to the RC.
On the time line the text F I : L T will appear shortly every
5 second but the unit(s) will continue to operate normally.
Filter warning can be reset by the building manager in
parameter P 40 and by pressing for more than 10 sec.
NOTE
Once the filter has been replaced, do not forget to reset
the filter counter.
Press for more than 10 sec.

10.3 Filter replacement
Filters must be properly maintained and replaced in order to
ensure proper air cleaning efficiency. Dirty filters will reduce
the air volume handled by the unit, thus adversely affecting
its performance. The length of time between cleaning of
filters is dependent upon the environment. A 6 to 12 month
interval cycle is normal, different servicing may be required
in some cases. Record the time interval in the maintenance
log for future reference.
Only original TripleAqua M5 filters in replaceable casing are
to be used and are fitted as standard and can be replaced by
gently removing the clamps on both side of the unit.
1. Turn off the electrical power source.
Allow the fan wheel to stop.
2. Loosen two clamps at the rear of return filter section
as shown below:
3. Pull out the filter-frame(s)
4. Follow the opposite procedure to re-install
the filter and frame.
5. Re-connect the electrical power source.
In case of a Return plemum box, this box needs to be
removed first.
The return plenum box can be removed from the unit
casing by unscrewing the plenum box. CAUTION: Due to the
dimensions and weights of the return plenum, at least two
installers are recommended to do this step for safety.
10.4 Additional maintenance
Brush the finned surface with a soft brush, brushing parallel
to the fins, taking care not to bend the fins. Brushing should
be followed by a vacuum cleaner. Compressed air can also
be used by blowing air through the coil fins from the leaving
air side, again followed by vacuuming. If fins are damaged, a
fin comb can be used to straighten the fins.
For a deeper cleaning, i.e. when unpleasant odors or similar
appear, spray the finned surface of the coil with a neutral
cleaning solution and rinse thoroughly. Do not use strong
acids and strong base cleaners. Strong alkali cleaners
containing sodium, potassium or ammonium hydroxide are
not recommended as they corrode aluminum tubes and fins.
Strong ammonium hydroxide cleaners will cause stress
corrosion cracking of tubes. Cleaners may decompose
over time producing organic acids that lead to corrosion.
Failure to maintain a clean coil will result in reduced airflow,
performance and increased power consumption. Check the
coil at every inspection and clean when needed.
10.5 Water treatment
Proper water treatment is a specialized industry and
therefore it is recommended to consult an expert in this field
to analyze the water for compliance with the water quality
parameters and to specify the appropriate water treatment
program. The expert may recommend rust inhibitors,
scaling preventative, antimicrobial growth agents or algae
preventatives. Anti-freeze (glycols) may also be used to
lower the freezing point.
All TripleAqua coils are constructed of copper tubes and
headers and brass and bronze alloys are present in the valve
packages. It is the end user’s responsibility to ensure that
any of the water delivery components are compatible with
the treated water. Failure to provide proper water quality will
void the fan coil unit’s warranty. See also section 12 of the
engineering manual. Water quality should meet the VDI2035
to obtain the full product warranty.
10.6 Drain pan cleaning
The drain pan is made of stainless steel. It may be required
to clean the drain pan. The drain pan can be cleaned with
non-aggressive cleaning products. Replace the drain pan as
original.
Loosen the connecting screws at both sides of the unit and
disconnect the drain connection.

During the draining of the circuits, do not
let glycols overflow in the surrounding
atmosphere. The circuit must be drained
using suitable recovery equipment.
For the disposal, contact the competent authority for
information.
Unless otherwise specified, the maintenance operations
listed below may be carried out by any trained maintenance
operator.
Open each line that supplies the unit, including the ones of
control circuits. Make sure that all disconnecting switches
are secured in the off position. The power cables can be
disconnected and disassembled. Refer to Chapter 4 for the
position of connection points.
Remove all the refrigerant from the refrigeration circuits of
the unit and store it in suitable containers, using a recovery
unit suitable for flammable refrigerants. If its characteristics
have remained the same, the refrigerant can be used again.
Contact the competent authority to obtain information
about disposal. The oil in each refrigeration circuit must
be drained and collected into a suitable container; then it
shall be disposes of in conformity with local regulations that
apply to the disposal of waste lubricants. Any oil spillage
must be recovered and disposed of in like manner.
Isolate the unit’s heat exchangers from the external
hydraulic circuits and drain the heat exchange sections of
the plant.
If no shutoff valves have been provided, it
may be necessary to drain the whole plant.
If a glycol solution or a similar fluid has been
used in the hydraulic circuits, or if chemical
additives have been added to the circulating water, the
circulating fluid MUST be drained in a proper way.
For NO reason shall a circuit containing glycoled water or
a similar solution be discharged directly into the drains
or surface waters.
After draining operations, the piping of the hydraulic
networks can be disconnected and disassembled.
Once they have been disconnected as specified, the
packaged units can be disassembled in a single piece. First
