Instructions for unloading on the site as well as installation and connection |
This type of bracket at the bottom of Geniox units in the
sizes 20 to 31 is reinforced for lifting the unit. Mount a
shackel in each of the 4 brackets that should be suitable
for lifting the weight of the section. The weight of the
section is printed on the label placed on the inspection
side of the unit.
13
Caution
Do not lift the section in the 4 brackets at the top of the section, because those brackets are not mounted
on profiles that are bearing. The connection between these profiles at the top of the section is not designed
to lift the bottom of the section with the heavy components. There is a potential risk that the bottom with
the heavy components may fall down with serious risk of injury and damage to property.

Caution
For units with steel plate roof, the steel plates are delivered uninstalled on a separate pallet. Do not step or
walk on the plates.
15
I.1.9Pre-assembly storage
The AHU must be protected from the weather and accidental impact. Plastic packaging must be removed and the unit
covered with tarpaulin or similar materials. In order to minimize condensation, sufficient air circulation must be ensured
between the covering and the unit.
I.1.10Tilt less than 30˚ during transportation of the section with heat pump
During transportation, the unit section must always be in the upright position or tilted less than 30˚. If it is necessary to
tilt the unit more than 30˚, the suction pipe of the compressor must point upwards to prevent the escape of oil from the
compressor sump.
I.1.11Transport of rotary heat exchanger — always in vertical position
During transportation, the unit section must always be in the upright vertical position and never in a horizontal or tilted
position. The rotary heat exchanger is not constructed for transportation in a horizontal or tilted position.
I.2Installation - mechanical
I.2.1Free area in front of and above the unit
Important
When positioning the unit on the site, it must be ensured that an area with the same width as the unit is
kept free for service and inspection and also for replacement of fans and exchanger, if needed. The width of
the free area must be at least 900 mm.
output |
Important
For safe access to the cabinet with electrical components, if the cabinet is placed on top of the unit, the free
area from the upper edge of the cabinet to the ceiling must be at least 700 mm.

I.2.2Supporting surface
Caution
Duct work must be sound insulated and must not be mounted directly on beams, trusses or other critical
building parts.
Caution
The surface beneath the unit must be level, horizontal and vibration-free. The surface must be able to
withstand the load of the AHU. Weights of the sections are written in Annex 2.
I.2.3Adjustable feet under legs or base frame and transport of sections
Adjustable feet are provided in a carton box placed inside the unit. Adjustable feet are delivered for indoor units and
not for outdoor units.
Sections can be transported on the site by hand manual forklifts or similar. The frame profiles in the edges of the sections have carrying capacity for lifting by the hand manual forklifts.
I.2.4Base frame assembly
Base frame is delivered unassembled for the indoor units that are delivered in sections on pallets. Assembly of the base
frame is illustrated on 4 pages in a manual in a plastic bag which is attached to one of the large base frame parts.
The 4 pages with the illustration regarding the assembly of the base frame are also available in this user manual in Annex 4, 5, 6 or7.
There are two types of base frames:
1. 118 mm high base frames
2. 218 mm high base frames
There are 4 different manuals and each of them illustrates the assembly of the 4 different types of base frames:
1. Manual about the 118 mm high base frames for AHUs in the sizes from Geniox 10 to Geniox 18. The name of this
manual is – Base frame 118 sizes10 - 18
2. Manual about the 118 mm high base frames for AHUs in the sizes from Geniox 20 to Geniox 31. The name of the
manual is – Base frame 118 sizes20 - 31
3. Manual about the 218 mm high base frames for AHUs in the sizes from Geniox 10 to Geniox 18. The name of the
manual is – Base frame 218 sizes10 - 18
4. Manual about the 218 mm high base frames for AHUs in the sizes from Geniox 20 to Geniox 31. The name of the
manual is – Base frame 218 sizes20 - 31
Mount adjustable feet with a distance of maximum 1500 mm between each foot under the base frame. The base frame
can now be levelled by the adjustable feet. The next step is to place and assemble AHU sections on the base frame.
I.2.5Base frames for outdoor units
Outdoor units must be installed on 218 mm high base frames and are always fitted to the AHU sections. Hot-dip galvanized base frames are recommended for outdoor units. Systemair delivers these base frames without the above mentioned adjustable feet.
I.2.6Outdoor units — support under the base frame of the unit
The installer must provide a frame that supports the base frame of the unit under the inspection side and under the
back side of the unit. The frame must support the base frames of the unit under the entire length of the unit.
output |
Instructions for unloading on the site as well as installation and connection |
Caution
To avoid that the unit may tilt during storm the base frame of the unit must be properly fastened to the
frame provided by the installer
I.2.7Installation on the site of unit sections at the base frame when sections are
delivered on pallets
17
Caution
It is strictly forbidden to lift a section under the top of the section. The plastic corners and brackets are not at
all reinforced for lifting the unit under the top. There is serious danger that the bottom with the heavy
components will fall down with the risk of serious injury and damage to property.
Lift up the section by hand manual forklifts to the level where the underside of the section is even with the overside of
the base frame.
Pull the section to the correct position on the base frame
by lifting straps – it is maybe necessary to support the
section by heavy duty furniture trolleys (see the photos
below)
Example of heavy duty furniture trolley turned with the
wheels upwards. Placed in this way on the forks of the
hand manual forklifts the heavy duty furniture trolleys are
suitable for safe and careful rolling of the unit sections
over the base frames.

Example of very heavy duty furniture trolleys. Turned
with the wheels upwards and placed on the forks of hand
manual forklifts these heavy duty furniture trolleys are
very suitable for safe and careful rolling of the unit sections over to the base frames.
Pull sections together with a strap. We recommend the
shown type of strap because this type is not damaging
the frame profiles in the bottom of the units. An example
of strap is shown to the right. Note! Do not place the
strap on the vertical profiles because the plastic corners
and the profiles are not at all reinforced for the heavy
load and stress that is created by the tensioner when a
section is pulled along the base frame. To avoid any load
and stress on the plastic corners the strap must be carefully placed on the bottom profiles of the unit when sections are pulled together.
Note! Never — place the strap on the vertical profile too close to a corner, because the plastics corners and the profiles are not at all reinforced for the heavy load and stress created by the tensioner when a section is pulled along
the base frame or on the floor.
output |
Instructions for unloading on the site as well as installation and connection |
Place the strap on the bottom profiles of the unit to avoid any load and stress on the vertical profiles when sections are
pulled together along the base frame. The sections must be pulled fully and tight together with the strap is placed on
the bottom profiles. Do not pull and slide a section unless the strap is placed on the bottom profile.
19
When the sections are pulled fully together it may be helpful to place the strap halfway up on the unit to press the sections fully together so that the rubber seals are closing 100% tight. Only gentle tension is allowed because the vertical
profiles are not reinforced for brutal stress in this direction and they may be bent.

Sections are mounted to base frames with self-drilling screws. In the base frame you will find a sufficient number of 5
mm holes that are prepared for the self drilling screws. In this picture you are standing and you are watching the assembled base frame on the floor or roof.
Use self-drilling screws — 4,8 X 18 mm — to be screwed upward through the holes into the bottom profile of the air
handling unit Note! A screw must be placed in every hole to achieve the necessary strength. In this picture you are lying on the floor or roof looking upward under the base frame. The screws will not be visible, when you are standing beside the unit looking at the unit
I.2.8Joining the AHU sections
The sections must be placed on the base frame and if the unit is delivered with 150 mm legs, the sections must be positioned directly in line with each other.
Ensure that the internal factory-fitted rubber sealing is undamaged
output |
Instructions for unloading on the site as well as installation and connection |
The sections are then to be positioned directly opposite
each other. If the sections are built with legs, the adjustable feet can be used to get the sections in line and at the
same height.
Press the sections hard together so that the rubber profiles are so flat that the iron frames of the two sections
are joined. Strap with tensioner is suitable for pressing
the sections hard together.. Note! Do not place the strap
on the vertical profiles because the plastics corners and
the profiles are not at all reinforced for the heavy load
and stress created by the tensioner. To avoid any load
and stress on the plastic corners and the profiles the
strap must be carefully placed on the bottom profiles of
the unit.
21
The sections must then be locked permanently together
with 8 mm bolts and nuts. Bolts and nuts are not delivered from Systemair

I.2.9Fitting the ductwork
Flexible duct connections between AHU and ductwork must always be installed. Be sure that flexible duct connections
are almost fully stretched. (Flexible connections are ordered as accessories and they are placed inside the unit). At the
fan outlet on a centrifugal fan, the duct size should be as close to the outlet size as possible. Avoid blockage and turbulence at the fan outlet.

Instructions for unloading on the site as well as installation and connection |
I.2.10Risk of stack effect by vertical ducts and wind pressure on louvers
Important
The Systemair air handling units can be ordered and delivered without dampers, and the installer/user must
check that duct systems with the described risk of stack effect (chimney effect) will be provided with
dampers and spring return motors.
On special occasions stack effect – also called chimney effect – in the ducts create airflows that drives the impellers by
turned off motors.
A rotating impeller is a potential hazard during cleaning and maintenance of the unit. Eliminate this airflow by dampers
with spring return motors for automatic closing of the dampers - even by power failure.
I.2.11Remove transport brackets – when spring mounts are installed
I.2.11.1 Impeller diameters 220 – 560 mm
If the fans are installed on spring mounts the transport brackets must be removed after the installation of the air handling unit. Two transport brackets are fitted to the coil springs during transport and installation. Both transport brackets
must all be removed to give the full anti-vibration function to the coil springs. The transport brackets are made more
visible with yellow labels. After removal of the transport brackets they must be disposed of safely.
23
I.2.11.2 Impeller diameters 630 – 1.000 mm
If the fans are installed on spring mounts the transport brackets must be removed after the installation of the air handling unit. Four transport brackets are fitted to the coil springs during transport and installation. The four transport
brackets must all be removed to give the full anti-vibration function to the coil springs. The transport brackets are made
more visible with yellow labels, as shown in the picture below. After removal of the transport brackets they must be
disposed of safely.

After disposal of the transport brackets the yellow label on the outside of the fan inspection door has no function and
should be removed.
I.2.12Refitting of guards
The guard is a safety guard installed inside the door. Tools are necessary for the removal of the guard. If the guard has
been demounted during the installation on the site, the guard must be refitted before startup of the unit.
Use an Allan key — size 6 or size 8 — for refitting the
safety guard. Replace the vibration damping rubber list if
it is damaged.

I.3Installation - electrical
I.3.1Description
The position of components is shown and described in Annex 2.
Connections to terminals are shown in the wiring diagram.
When control of constant pressure in the ducts (also called demand controlled capacity) is required, the pressure transmitters must measure in the duct system at places where all pressure changes can be registered accurately for reliable
pressure control. This placement is left to the customer’s free choice.
It is important to achieve a constant pressure – also for the most faraway diffusers.
I.3.2Wiring diagrams
The wiring diagrams are printed in separate manuals delivered with the units.
The wiring diagrams are not unique for the order specific units, but it is standard wiring diagrams with data about all
configurations of the units. Hereby the wiring diagrams will inform about components that are not ordered and delivered. See the order confirmation and Annex 2 with exact information about the accessory components that are ordered
and delivered.
The wiring diagram includes:
• General description, Circuit diagrams, Cabinet layout, Terminal matrix and Cable plan.

I.4Installation – Pipes for water – hot and chilled, valves and drains
I.4.1Description
If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Water trap(s) –
standard or optional - is (are) necessary to ensure escape of water from the tray under plate heat exchanger and (or)
cooling coil. Water trap(s) is (are) stored in a carton box placed inside the unit.
I.4.2Pipe connections
Connection pipes on heating- and cooling coils are provided with external thread. Drainage outlets on drip trays are provided with straight pipe for quick connect fittings on the pipe with the water trap.
I.4.3Possibility of extracting components from the unit
Pipes and cables must not obstruct the inspection doors and components which can be extracted from the unit. Potential components for extraction are filters, fans and rotary heat exchanger.
I.4.4Pipe connections to batteries
I.4.4.1Heating coils
Pipes for hot water must be protected by insulation against frost and loss of heat. Further protection against frost can
be obtained by installing electrical heating wires around the pipes and under the insulation combined with temperature
sensors and a control system. Pipes, insulation, electrical heating wires, control system for heating wires and circulation
pump are not delivered by Systemair.
I.4.4.2Cooling coils
If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Pipes for cooling
must be protected by insulation against condensation on the pipes and loss of cooling in the summer. Pipes and insulation are not delivered by Systemair.
I.4.4.3Rigid pipe mounting brackets for valves, circulation pumps and pipe system
The coil and pipes from the coil are not constructed to withstand the weight and stress from valves, circulation pumps,
long pipes and insulation of pipes. The system must be supported carefully in rigid pipe mounting brackets to roof, floor
and walls.
I.4.4.3.1 Pipe connection to heating coils
The heating capacity of the coil with only 2 rows is independent of the connection of the hot water in equal flow or in
counter flow to the direction of the air, but connection of the hot water to the pipe marked for inlet and the return

water to the pipe marked for outlet is very important to ensure that the sensor for transmission of the water temperature really will be placed in a return circuit of the coil (Screw-joint for the water temperature sensor is welded in the
main collection pipe for return water).
For the frost protection of heating coil, the water temperature in the coil is transmitted to the controller The controller
always generates a signal to the valve motor that keeps a sufficient flow of hot water to protect the coil against frost.
This frost protection is also activated when the running mode is “off”.
Coils with 3 rows or more must always be connected in counter flow to the airflow.
Note:
If glycol is added, the glycol must be without additives and auto glycol must not be used.Automatic bleeding
has to be installed at the highest point of the 2 pipes — supply or return pipe.
If the heating battery is built with 3 or more rows, the water flow must be in counter flow to the direction of the air.
To protect against frost a temperature sensor for the
transmission of an analog signal to the controller is placed
in a pipe on the collection pipe for return water. The sensor must be fitted water tight with a cap in the pipe before water under pressure is in the battery. The pipe for
the sensor is soldered on the collection pipe and it is important to hold contra on the pipe, when the cap is
tightened.
Battery seen from above. The sensor measures the
water temperature of the water inside one of the small
pipes for return water in the battery. The sensor reduces
the area in this pipe and hereby also the flow of warm
water in this pipe. The temperature in this pipe is reduced
more than the temperature in all other pipes by the airflow through the battery. Because the lowest temperature in the battery probably is measured here, this system
creates early and safe warning of frost.
It is important that the cap is tightened sufficient to keep
the sensor system fully water tight.
I.4.4.3.2 Pipe connection to cooling coils for chilled water
Coils with 3 rows or more must always be connected in counter flow to the airflow.
Caution
The glycol must be without additives and auto glycol must not be used.
Automatic bleeding has to be installed at the highest point of the 2 pipes — supply or return pipe

I.4.4.3.3 Valve motor and valve for heating
The valve and valve motor are not installed. 2-way or 3-way valve is available.
I.4.4.3.4 Valve motor and valve for cooling
The valve and valve motor are not installed. 2-way or 3-way valve is available
I.4.5Draining condensate water
Drip trays for collection of condensate water are installed under plate heat exchanger, run-around coil and cooling coil.
Each drip tray is provided with a drainage outlet. A water trap is always necessary. To avoid freeze ups and frost bursts
of water trap and pipes, sufficient insulation is recommended and installation of heating between the insulation and
water trap/pipes could even be necessary (insulation, heating and controller for the heating are not delivered by
Systemair).
I.4.6Draining condensate water from heat exchanger
Condensate from the plate heat exchanger or run-around-coil is collected in the drip tray. Heavy negative air pressure
in this section prevents the water from flowing out of the drainpipe. A water trap with sufficient closing level of the
water is essential to ensure that condensate water flows out of the unit. The closing level of the water trap must be estimated correctly to ensure safe escape of the water (see the illustration and estimate the minimum closing level according to the table).The pipe diameter of the water trap and sewage system must be identical to the pipe diameter of
the drainage outlet from the tray.
Remember to check that there is water in the water trap.

Necessary closing level that is H1 minus H2 — for example for the negative pressure 500 Pa — equal to 50 mm
of water column is 60 mm because the 50 mm corresponds to the negative pressure is lifting the water 50
mm and an excess height of 10 mm enables the water to
flow out through the water trap into the sewage system.
With the negative pressure at 750 Pa, an excess height of
20 mm enables the water to flow out through the water
trap into the sewage system.

This type of water trap for sections with negative pressure and a ball that is sucked down into its seat for blockage of air flow into the section is available from
Systemair. The above-mentioned heights — H1 and H2 —
also apply to this type of water trap. The great advantage
of this type of water trap for sections with negative pressure is that this type does not require water at the bottom
to close for air flow backwards into the section. Condensate water will escape through this type of water trap —
even after long periods without any water to close for air
flow backwards through the trap.
This water trap is optional and must be ordered separately. Installation of water trap is not included.
The water trap in this picture has the delivered standard
length of H1 of 150 mm and with the adjustable length of
H2 adjusted to 55 mm, this set-up allows water to flow
out at a negative pressure of 750 Pa, because the closing
level that is H1 minus H2 is 95 mm and with 75 mm corresponding to the negative pressure lifting the water 75
mm and an excess height of 20 mm that enables the
water to lift the ball and to flow out through the water
trap into the sewage system..
H1 must be shortened on the site by the installer —
sometimes to only 100 mm — because the height of the
low version of the base frame is only 118 mm. The adjustable length of H2 must be reduced to the minimum of
40 mm. According to the values in the above table, this
allows Water to flow out at a negative pressure up to 500
Pa because the closing level that is H1 minus H2 is 60
mm with 50 mm corresponding to the negative pressure
lifting the water 50 mm and an excess height of 10 mm
that enables the water to lift the ball and to flow out
through the water trap into the sewage system.
To avoid freeze ups and frost bursts of water trap and
pipes, sufficient insulation is recommended and installation of heating between the insulation and water trap/
pipes could even be necessary (insulation, heating and
controller for the heating are not delivered by Systemair).
The insulation must be easy to remove above the cap, because the ball and the seat for the ball must be cleaned
regularly to allow the ball to close air-tight to the seat.
I.4.7Draining condensate water from cooling battery —
If the cooling battery and the drip tray are placed in the unit where negative pressure (underpressure) occurs, the closing level of the water trap must be estimated correctly. See the above-mentioned information in I.4.6 Draining conden-sate water from heat exchanger. If the cooling battery and the drip tray are placed in the unit where positive pressure
(overpressure) occurs, the closing level of the water trap must be estimated correctly as shown on the illustration below. A water trap is optional and installation of the water trap is not included.

R.4Filters – always replace filters with new filters with the same characteristics to
maintain SFP value
Filters in supply air and in extract air always have the same sizes of frames and the number of filters for supply air and
extract air are always the same. REMEMBER to order filters for supply air as well as for extract air.
To maintain the factory-calculated SFP values for the air-handling unit, it is very important that filters with the same
characteristics for start pressure as well as lifetime replace factory-mounted filters.
To achieve the most favourable SFP values, the factory-mounted filters represent the lowest achievable start pressure
as well as the longest achievable lifetime. If other filters with higher start pressure and shorter lifetime replace the factory-mounted filters, the user will experience smaller airflow and/or consumption of more electricity, and the SFPv value calculated by Systemair according to the Eurovent certification will not be achieved. Poor SFPv values will be
detected by tests according to commissioning standards, DGNB, LEED or BREEAM sustainability standards and locally
defined performance standards (the SFPv is with new clean filters).
Filter frame for bag filters must be of NON-PVC plastic to ensure safe disposal by incineration.
For each individual air handling unit you will find the data for the factory-mounted filters in Annex 2 that is always provided in a cover placed inside the air handling unit when the air handling unit is delivered to the final site. Annex 2 is also always available from Systemair if you can inform us of the production number of the air handling unit. The
production number is always printed on the so-called machine card that is attached to the unit. You will find an example
of this machine card in section d.2.1 of this manual.
The factory-mounted filters comply with indoor air quality demands of customers and with the SFP values according to
local legislation.
These air handling units are available with filters that comply with the below-mentioned filter classes:

R.4.3Bag filters
Turn the unit off and wait for 2 minutes till unit completely stops. Used filters can be pulled out. Store the used filters
immediately in plastic bags to avoid that dust pollutes the environment. Geniox units in the sizes 10 – 31 are provided
with a very corrosive-resistant and reliable system, where filters are slid into the units in a lower and upper durable uprofile of plastic/rubber Check the upper and lower U-profile for damage and check the vertical rubber profile on the
back wall as well as the rubber profile on the inspection door for damage. The new filter bags must be pushed carefully
into the unit in order to ensure that they are sealed properly. The filters must have vertical bags.

ONE self-adhesive foam strip must be placed on the vertical frame of EACH filter to avoid major air leakage through
the vertical opening between 2 filters. Please note – only
ONE self-adhesive foam strip must be placed on the vertical frame of EACH filter – Please establish the practical
rule that the self-adhesive foam strip is placed on the vertical side that is visible from the inspection side. Those
very important self-adhesive foam strips are usually not
delivered by the suppliers of filters. The customer must
order those self-adhesive foam strip from a supplier of
foam strips. Width of the foam strip is about 15 mm and
thickness of foam strip must be exactly 8 mm. If the thickness of the foam strip is less than 8 mm, there will be a
gap for leakage between the filters. If the foam strip is
more than 8 mm the row of filters in the U-profile will be
too wide making it impossible to close the inspection
door. Note! The staff must have the self-adhesive foam
strips available when they go to the air handling unit.
Without those self-adhesive foam strips, any change of
filters is impossible.
Remove the protection from the self-adhesive side of the
strip.

not fully even with the end of the U-proflle an additional
self-adhesive profile must be added to avoid any gap between the rubber profile on the inspection door and the
last filter.
The end of the last filter is fully even with the end of the
U-profile. The rubber profile on the inspection door will

Caution
This procedure requires knowledge of proper ESD protection; i.e. an earthed wristband must be used!
When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery for backup of program
memory and real-time clock has become too weak. The battery is replaced as described below. A backup capacitor
saves the memory and keeps the clock running for at least 10 minutes after the power supply is removed. Therefore, if
the battery replacement takes less than 10 minutes, there will be no need to reload the program, and the clock will
continue to run normally.
The replacement battery must be of the type CR2032.
1 Remove the cover by pressing down the locking tor-
ques at the edge of the cover using a small screwdriver, and at the same time pulling the edges
outwards.
2 Grip the battery firmly with your fingers and lift it up-
wards until it rises from its holder. Press the new battery firmly down into place. Note that to preserve
correct polarity; the battery can only be inserted the
“right way round”.

R.6Other functions to maintain
R.6.1The unit
It is very easy to remove inspection doors for extraordinary good access to cleaning, service, repairs and replacement of components in the unit. Lift the stainless
steel shaft in the hinge to remove the door
The unit should be cleaned once a year when operating with normal air quality for comfort ventilation with no special
hygiene requirements.
To clean the unit, dry it off with a dry cloth, or use water mixed with a non-corrosive cleaning medium.
Any corrosion — for example the bottom of the section for outdoor air intake and the bottom of the section for exhaust
air outlet must be cleaned off immediately, and the surface treated.
In special operating conditions, where the air is aggressive or very humid, for example, or where there are special hygiene requirements, the unit shall be cleaned more frequently as required.
Cleaning medium and method should be adapted to the relevant conditions. Any corrosion should be cleaned off immediately, and the surface treated.
Closing mechanisms are to be lubricated at least once a year. Synthetic door hinges are service free. Seals around inspection doors are to be cleaned at least once a year and are to be checked for leakage.
It is recommended to treat the seals with a moisture repellent agent.
All seals are to be inspected at least once a year and are to be repaired if necessary.
Grilles for air intake and exhaust air outlet are to be cleaned at least once a year to prevent blockage.
R.6.2Dampers
Rubber seals between the damper blades and the frame
are to be checked once a year. These seals are not to be
lubricated or treated in any other way.

R.6.3Rotary heat exchanger
R.6.3.1Rotor
The rotor is to be checked at least once a year to ensure that it can turn freely and easily. This can be done by removing
the belt drive at the motor and then turning the rotor manually with a hand on the peripheral rotor casing. At the same
time the brush seals are to be checked for damage. The bearings are factory lubricated and do not require any service
lubrication. During operation the rotor can become dirty. The rotor can be cleaned by blowing through with compressed
air.
To ease inspection and service the rotor can be pulled out of the sizes 10, 11, 12, 14 and 16.
R.6.3.2Motor and belt drive
The bearings are factory lubricated and do not require any service lubrication. The belt drive is to be checked for correct
tightness and that it is undamaged. On smaller AHU, the rotor is fitted with an elastic belt drive and supplied with a reserve belt on the rotor. This belt drive does not require service and cannot be shortened. A new belt can be fitted using
specialist tools. On larger heat exchangers the rotor has a V-belt with a belt connector. If the belt is no longer tight, it
must be shortened to a length which enables the motor base frame tightening spring to hold the belt tight. If new
screws are used for the belt connector, they must not have a length which exceeds the thickness of the belt and connector. Remove the excess, if any, with a file.

Adjustment and maintenance operations |
R.6.4Cross flow and counter flow exchanger
Note:
Once a year the edges of the heat exchanger plates are to be checked for cleanliness and damage.
If there is dust on the edges of the plates, remove it with a soft brush. If grease or other such substances are present,
then the edges must be washed using grease dissolving detergents.
51
R.6.4.1By-pass damper
The damper blades are fitted with synthetic bearings requiring no lubrication. Each damper blade is driven by a gear
drive of a temperature resistant glass fibre reinforced PA6 nylon composite. The steel rods and brass bushes do not require lubrication. Air-tightness of the dampers, when the damper motor is in the closed position, must be visually
checked once a year. The damper motor is to be adjusted if the damper does not close tightly.
R.6.4.2Condensate water drain
At least once a year the drip tray beneath the heat exchanger, as well as the drain and the water trap must be cleaned.
Take care that there is sufficient water in the water trap. If a droplet eliminator has been fitted, this must be checked
once a year and cleaned if necessary.
Drip tray with slope is not supported for the weight of a person. Do not walk or stay in the drip tray.

Demount this type of water trap for careful cleaning.
R.6.5Run-around heat exchanger
A heat recovery system of this type consists of a heating coil in the supply air- flow and a cooling coil in the exhaust
air- flow. After an extended running period (normally a few years) dust particles can accumulate on the surface of the
coils. This can reduce the efficiency of the coils. Cleaning must be carried out with the utmost care to ensure that the
coil fins are not damaged.

Adjustment and maintenance operations |
The piping system must be vented once a year as air in the system can significantly reduce the capacity of the coils.
R.6.5.1Pump and pressure expansion
The service instructions issued by the pump manufacturer must be followed. The pressure expansion system must be
checked once a year. If necessary, the pressure must be increased to the correct level.
R.6.5.2Condensate water drain
Once a year clean the drip tray beneath the heat exchanger, as well as the drain and the water trap. Take care that
there is sufficient water in the water trap. If a droplet eliminator has been fitted to the cooling coil, this must be checked
once a year and cleaned if necessary. See the explanation above.
R.6.6Heating coil
After an extended running period (normally a few years) dust particles can accumulate on the surface of the coil. This
can reduce the efficiency of the coil. Cleaning must be carried out with the utmost care to ensure that the coil fins are
not damaged. The piping system must be vented once a year as air in the system can significantly reduce the capacity
of the coil.
R.6.6.1Heating battery

SInstructions to enable adjustment and maintenance safely
S.1Protective measures and additional protective measures
Adjustment and maintenance must be done by skilled technicians – usually based on service contracts for some years
or long-term ESCO contracts.
The units are provided with guards to avoid unintended hazards and injury because of rotating parts in the unit. The potential sources of harm are the fans with fast rotating impellers. Hazards from the impellers are obvious during operation, but when power is cut-off, the impellers are still potential hazards due to after-run for at least 20 seconds. Notice
that even cut-off the impellers are still potential hazards.
The fan guard’s are the inspection doors and the doors are provided with locks. Inside the doors are additional protection installed – guards that only can be removed by use of tools.
Other motor-driven parts are dampers with damper motors and rotary heat exchangers, but the movement is so slow
that guard measures are not necessary. Just keep your hands away from places with risk of injury.
Use particulate respirator when filters are replaced.
S.1.1Necessary protection measures prior to start-up
Ensure that all protection measures are installed correct before start-up.

S.1.1.2Configuration of frequency converters with installed guard
A frequency converter is mounted beside the fan in some units. If the configuration of frequency is carried out with the
fan in operation, the guard must be installed for safety reasons and a long cable must be installed between the frequency converter inside the unit and the control panel outside the unit.
S.1.2Safe adjustment and maintenance
Before maintenance and repair, the unit must be switched off by switching off the automatic circuit breakers and block
them by padlocks. Note that lamps must be switched on during maintenance (lamps are an accessory – only installed,
if ordered).
Use cut-resistant gloves for protection against injury from sharp metal plate edges. Use CE-marked gloves for this purpose. Use helmet during maintenance work in the unit.
S.1.3Personal protective equipment for maintenance staff – health and safety
Use the below-mentioned personal protective equipment for maintenance:
• Cut-resistant gloves for protection against injury from sharp metal plate edges. Use CE-marked gloves for this
purpose.
• Helmet
• Particulate respirator – maintenance free including foam face-seal and adjustable pre-threaded headbands – for replacing filters.
• Padlock for locking the above mentioned automatic circuit breakers.
• Permanent magnet motor. The shaft must be blocked during repairs and maintenance of the electric system (the
motor generates electricity by rotation – for example that the wind and thermic drives the fan/motor).

8.1Overview
• Mount rails A1, B2, C3, D4, E5 on the unit for support of trapezoidal roof plates (mount also rails Y and Z on units of
the size 30 and on units that are larger than size 30 longitudinally at the centre- line of the units).
• Place foam bands – P – on the horizontal rails A1, B2, C3 and D4 for support of roof plates.
• Calculate overhang of the roof at both ends of the unit and mount roof overhang profile – G1 on the first trapezoidal
roof plate – F1 before the roof plate is mounted.
• Place and mount roof plates F1, F2, F3 and so on.
• Remember foam bands on the side laps between roof plates to prevent rainwater from passing through.
• Place roof overhang profile – G5 at the other end of the unit before the last roof plate is mounted.
• Mount sides and corners on the roof.
• Apply sealing where plates are joined to ensure water resistance - even in stormy weather.
8.1.1Mount rails. Units of size 10, 11, 12, and 14
Squeeze sealant in sufficient quantity between the underside of the rails A1, B2, C3, D4, E5 and the horizontal top side
of the unit before the rails are mounted. This means that the rails are standing on sealant to achieve the tightest
connection between rails and unit to prevent rainwater from passing under the rails and into the unit. Mount the rails
A1 and B2 on the front side (the side with the inspection doors) – use the simple self-drilling screws without the sealing
washer – see the illustration of the screw below.
Note:
Rail B2 fits into the rail A1, and this offers the advantage that the rail B2 can be slid inside the rail A1 to
adjust the length of rail B2 accurately to the length of the unit. In this way it is not necessary to spend time
and effort cutting the rail B2
Mount the lower rails C3 and D4 on the back side of the unit.
Note:
Rail D4 fits into the rail C3, and this offers the advantage that the rail D4 can be slid inside the rail C3 to
adjust the length of rail D4 accurately to the length of the unit. In this way it is not necessary to spend time
and effort on cutting the rail D4.
Mount vertical rail – E5 - with the roof slope at each end of the unit
Caution
It is important to place a screw in each hole – even though the number of holes for screws seems to be
very large, a screw in each hole is necessary as the stress on the roof during stormy weather is extremely
high.
8.1.2Mount rails. Units of size 16 and units larger than size 16.
On units of size 16 and on units that are larger than size 16, rails A1, B2, C3, D4, E5 must be mounted on the unit for
support of trapezoidal roof plates, but also rails Y and Z must be mounted longitudinally at the centre-line of the units
to hold the trapezoidal roof plates.
Squeeze sealant in sufficient quantity between the underside of the rails A1, B2, C3, D4, E5 and the horizontal top side
of the unit before the rails are mounted. This means that the rails are standing on sealant to achieve the tightest
connection between rails and unit to prevent rainwater from passing under the rails and into the unit. Mount the rails
A1 and B2 on the front side (the side with the inspection doors) – use the simple self drilling screws without the sealing
washer – see the illustration of the screw below.
Note:
Rail B2 fits into the rail A1, and this offers the advantage that the rail B2 can be slid inside the rail A1 to
adjust the length of rail B2 accurately to the length of the unit. In this way it is not necessary to spend time
and effort cutting the rail B2.
Mount the lower rails C3 and D4 on the back side of the unit.

Note:
Rail D4 fits into the rail C3, and this offers the advantage that the rail D4 can be slid inside the rail C3 to
adjust the length of rail D4 accurately to the length of the unit. In this way it is not necessary to spend time
and effort cutting the rail D4.
Mount vertical rail – E5 - with the roof slope at each end of the unit.
Mount the rails Y and Z on the unit with the centre-line of the rails exactly over the centre-line of the unit. It is
longitudinal on the middle of the units to hold the trapezoidal roof plates.
Note:
Rail Z fits over the lower rail Y, and this offers the advantage that the rail Z can be slided on the rail Y to
adjust the length of rail Z accurately to the length of the unit. In this way it is not necessary to spent time
and effort on cutting the rail Z.
Caution
It is important to place a screw in each hole – even though the number of holes for screws seems to be
very large, a screw in each hole is necessary as the stress on the roof during stormy weather is extremely
high.
8.1.3Roof overhang along the long sides of the unit
The roof plates are longer than the width of the unit to ensure sufficient overhang along the sides of the unit.
The overhang is 100 mm along each side of the smallest unit – size 10.
The overhang is 150 mm along each side of the units – size 11, 12, 14.
The overhang is 175 mm along each side of the biggest units – including size 16.
8.1.4Calculation of the overhang at the ends of the unit. Mount overhang profile – G1.
The roof must be between 200 and 400 mm longer than the length of the unit to secure a roof overhang between 100
mm and 200 mm at the each of the 2 ends of the unit, and the length of this overhang must be calculated before the
first roof plate is mounted.
The unit is delivered with 2 similar overhang profiles - G1 and G5 - one for each end of the roof. Mount one of the 2
roof overhang profiles – G on a trapezoidal roof plate. Use the self drilling, painted screws with sealing washers - W see the illustration.
Note:
Foam bands - P – are necessary between the overhang profile G1 and the roof plate F1. See the illustration.
Self-drilling, painted screws supplied with sealing washer for the mounting of the trapezoidal plate to the roof
overhang profile.
The total cover width of the trapezoidal roof plates always changes with the pitch of 205 mm between the trapezoidal
ribs, making up a total length of the complete roof of - for example 2100 mm, 2305 mm, 2510 mm and so on. We call
this length of the total roof for RL and we call the total length of the complete unit for AL. The trapezoidal roof must
always be longer than the unit, to obtain a reasonable overhang called – XX - of the roof at both ends.
In the table below you will find 40 different lengths of roofs (always changing with the 205 mm) and the lengths of
units that are ideal for each of the 40 alternative roof lengths.
Measure the total length – AL of the unit – for example 5000 mm between the 4982 and 5182 mm mentioned in the
table below.
The mentioned length of roof – RL - for this length of unit is 5380 mm (the delivered trapezoidal plates can be
combined to this length - RL = 5380 mm). 5380 mm minus 5000 mm is 380 mm overhang for both ends, and 380/2
mm = 190 mm is the overhang for each end. Place the trapezoidal roof plate F1 with the roof overhang profile G1 on
rail E with an overhang of 190 mm.

8.1.5Foam bands between rails and roof plates – mount roof plates.
Place foam bands P between profiles A1, B2, C3, D4 and roof plates.
The trapezoidal roof plates are mounted with the self-drilling, painted screws supplied with sealing washer.
8.1.6Foam bands between roof plates
Mount the self-adhesive foam band – O - on the underlapping rib for water resistant and effective sealing due to the
small slope of the roof.
8.1.7Mount roof plates – some of them are overlapping by 2 ribs
The width of each plate is always 1025 mm and some of the plates have to overlap by 2 ribs to achieve the optimal
total length of the whole roof — see the illustration above.
8.1.8Mount overhang profile – G5 on the other end of the unit.
When the last trapezoidal plate (in this example F5) has been placed on the unit, the second roof overhang profile G5
must be pushed under the trapezoidal roof plate and mounted with the self-drilling, painted screw with sealing washer.
Mounting must be similar to the mounting of roof overhang profile under the trapezoidal roof plate at the other end of
the unit.
8.1.9Mount side profiles and corners along the edges of the roof to protect persons
Profiles N and O with the rectangular holes are for the long and lower side of the roof because rain can escape through
the holes. Mount the profiles type N first and the profile O last because the profile O goes over the profile N. Mounted
in this order, the profile O can match the end of the roof and the surplus length of the profile O will just cover part of
the previous profile N. Mount the profiles L and M along the long and higher front side of the roof. Mount the 4
protection corners.
8.1.10Apply sealing on plate joints to ensure water resistance.
Finish installation of the steel roof by sealing all plate joints with silicone to prevent rainwater from passing into the
unit. See examples below of joints to be sealed.
