1.2 --- Responsibility

Liebert Hiross accepts no present or future responsibility for
damage to persons, things or to the machine itself due to opera­tors’ negligence, failing to comply with the installation, operation
and maintenance instructions of this handbook, failed applica­tion of the safety norms in force for the system and the qualified
staff charged with the operation and maintenance.

1 . 3 --- I n s p e c t i o n

All units are fully assembled and wired in the manufacturing
plant. Before shipment they are charged with the necessary
quantities of refrigerant and oil and then tested at the operating
conditions normally required by the customer. The machine’s
hydraulic circuit is equipped with drain plugs and open vent
valves; the free ---cooling coils are supplied dry to avoid possible
problems due to frostin the storage period. Immediately inspect
the machine carefully on delivery to check for damage during
transportation or missing components; possible claims must be
made immediately to the carrier and the factory or its representa­tive.

1 . 4 --- G e n e r a l d e s c r i p t i o n

MATRIX R units with air ---cooled condensers have been de­signed and manufactured for producing chilled water.
They are also available in versions with a built -- -in freecooling
module, in versions with heat recovery for simultaneous heating
of thermal circuit water, with a pump assembly installed on the
machine and/or inertial buffer tank inside the machine; the chill­ing units can be equipped with several options indicated in the
price list.
The ”MATRIX R” product line has been designed utilising the
state---of---the---art techniques available nowadays in the indus­try, and includes all the components necessary for automatic
and efficient operation.

The Matrix R units are specifically designed for indoor installa­tion (protected from weather agents), for the connection with

ducts of condensation air in machine intake (if present) and
outlet.

Each unit is completely factory assembled; after evacuation, the
necessary quantity of refrigerant is added to the refrigerant cir­cuit(s) and the unit is tested.
All the unitsare equipped with one or two independent refrigerat­ing circuits, each one composed of: an air --- cooled condenser,
a hermetic Scroll compressor and a braze---welded plate evapo­rator. The components of the liquid line are the charging valves,
filters - --dryers, solenoid valve, shut--- off valve, moisture indicator
and thermostatic expansion valve.
The hydraulic circuit -- - with max. working pressure 5 bar --- is
made up on mod. 004---016 of hydraulic lines both in steel and
flexible EPDM rubber, connected by fittings and threaded joints,
on mod. 017 --- 032 of carbon steel pipes connected with
grooved---end (Victaulic) fittings and couplingsand include also
a flow switch (optional) and, in the freecooling versions, chilled
water coils and a three - --way valve.

The hermetic scroll compressors are complete with the following
protection/safety devices: oil heater (if necessary), electronic
protection monitoring the temperature of the motor windings
and the direction of rotation (the latter may be enclosed in the
electronics of the compressor or external, depending on the
model).

Fans are radial type, with aluminum reverse curved blades and
structure, statically and dynamically balanced, directly coupled
to a motor with external rotor. It is always available the fan speed
controlwhich normally is achieved through an adjuster with con­tinuous speed modulation.
By simply modifying the parameters(of the Microfacemicropro­cessor control), limiting the fan max. rotation speed, it is possible
to change the useful air static pressure (equal to the difference
of the static pressure between the delivery and suction ducts
connected with the unit).

The ”MATRIX R” water chillers are controlled by the ”MICROFA­CE” microprocessor, managing all the unit operating conditions.
The user can change and/or modify the operating parameters
through the display keyboard installed on the electrical panel.
The electrical control board is equipped with all the safety and
operating devices required for reliable operation. The compres­sor motors are equipped with protection on all three phases and
are started by three --- pole contactors.

2 --- Preliminary Operations

2.1 --- Operating limits

The units can operate within the indicated operating limits (see
Tab. 6). These limits apply to new machines, subject to correct
installation and maintenance.

S Ambient air minimum temperature: ---25ûC for Superchiller,

--- 1 0 ûC for Chiller (either Triac or EC fan);

S Maximum outdoor air temperature is in relation to each mod-

el, as indicated in Tab. 6. In any case outdoor temperatures
aver 45ûC are not admitted; such limits are determined by
electrical and electronic components fitted on units;

S Maximum water flow allowed: depending on the pressure

drop corresponding to the required thermal difference (usu­ally not lower than 3.5ûC --- 4 ûC);

S Minimum allowed water flow: compatible with a sufficient

evaporation temperature, to avoid the intervention of the
safety devices (to be evaluated for a thermal difference not
higher than 8ûC);

S Temperature range of the water exiting the evaporator: 4ûC

--- 1 5 ûC;

S Maximum temperature of the water entering the unit: 20ûC;

higher temperatures are allowed only at the system start--­up and not during normal operation;

S Maximum glycol concentration: 50% (35% with the optional

pump assembly installed on the machine);

1

S Minimum allowed glycol concentration: depending on the

minimum temperature of the ambient air expected at the
installation site (see Tab. a);

S Maximum difference of air side pressure (between the one

in the delivery duct and the one, possibly negative, in the
coil suction) equal to the max. one indicated in Tab. 9 next
to the max. signal = 10 V set on the microprocessor;

S Maximum pressure of the hydraulic circuit: 5 bar;
S Voltage range for the electric supply: 400 V

phase difference: 3%; tolerance on frequency: 1%.

Storage conditions: ---20ûC ÷ 45ûCforallMATRIXRmodels.

2.2 --- Sound pressure levels

The Tab. 7 shows the noise data for the units in standard config­uration (without pumps), operating continuously and measured
at 1 m from the coil side unit, with ducted air delivery and 50 Pa
of useful static pressure, in free field conditions.
The highest noise levels are detected for higher useful static
pressures of the air.

Note:
Avoid positioning in areas with possible reverberation of the
sound waves; acoustically insulate both the delivery and the in­take ducts (if installed); failure to do this can adversely effect the
noise levels.

2 . 3 --- T r a n s p o r t

S Handle the unit by lifting it with a crane from above;
S The lifting holes are positioned in the frame’s base (when lift-

ing, use spreader bars to protect the sides, see Fig. 3, Fig. 4
and Fig. 5).

Note:
Place the lifting tubes in the holes in the base indicated by ”LIFT
HERE”. Lock the ends of the tubes with the locking pins and
splits pins as shown in Fig. 3 and Fig. 5. As an alternative (on
mod. 004 --- 016 only), shackles/hooks (optional) fastened at the
base ends can be used as a lifting system: in this case the lifting
point must be on the vertical line passing through the machine’s
centre of gravity (as indicated in Fig. 4) to prevent any load im­balance.
The capacity of the lifting gear must be adequate to lift the load
in question. Check the weight of the units, the capacity of the lift­ing gear and ropes and the condition and suitability of the afore­mentioned equipment.

2.4 --- Foundations

S The unit must be placed on a level surface which will support

its weight.

S If necessary, position the unit on suitable anti---vibration sup-

ports that can be supplied as an option (in rubber or spring --­type). Refer to the manual ”Installation of the spring anti --­vibration supports” for their correct positioning.

S When positioned, level the unit.
Note:

For weight distribution see Fig. 6 and Fig. 7.
Note:

The weights and their distribution refer to standard units without
options; if the pump assembly, or other options are installed on
the machine, add the weights of the installed accessories to
those of the standard units (see Tab. 8).

2.5 --- Service area

S In order to allow free air flow or to enable the ducting installa-

tion and maintenance of the unit, a minimum area must be
left free of obstructions around the unit (see Fig. 1 and
Fig. 2).

S Avoid recirculation of hot air between the outlet and the out-

door intake of the air conveyed in the ducts, otherwise the
unit performance may be impaired or the standard oper­ation can be interrupted.

3 --- Installation

3.1 --- Aeraulic connections

The Matrix R units are arranged with connection flanges for the
air intake and delivery ducts; if the units are ordered with metal
filters to protect the condensing coils, the connection flanges for
theintakesideductingarenotsupplied,asthereisnoductto
enable the cleaning of such filter.

Connect the ducts fitting flexible joints to prevent transmitting
vibrations and to compensate thermal expansion. Check if the
holes on the walls --- where the intake and delivery ducts are
fitted --- are protected by suitable anti---rain grilles (equipped
with pre --- filter like the intake ones) to avoid water or dust to enter
in the chiller.

All fans are adjusted at the same speed, so that it is not necess­ary to install overpressure dampers next to each fan discharge.
The units are supplied with a setting in the microprocessor for
the max. fan speed of 50 Pa useful pressure; set the max. speed
according to the features required by the installation (see
Tab . 9) .

The units are supplied with the condensation air discharge up­wards; during the installation, it is possible to change the posi­tion of the air discharge opening (with right or left horizontal
direction) by simply inverting the position of the drilled panel
withtheclosedoneoftherequiredside(seesizedrawings).

3.1.1 -- External air temperature probe installation

Install the external air temperature probe (shipped inside the
electric panel), at the end of the air intake duct.
The bulb must be positioned as much outside as possible but
must not be exposed to direct sunlight or weather agents such
as rain or snow. The unit operation could be jeopardized if these
precautions are not applied.

If the intake side duct is not present, fasten the probe in the room
so that it can correctly detect the external temperature of the coil
intake outer air without being influenced by other external factors
(sun rays, rain or snow, other heat or radiation sources, etc.).

3.2 --- Hydraulic connections

3.2.1 -- Hydraulic circuit construction (Fig. a)

The piping must be connected to the chiller. Construct a chilled
water circuit as described below, see Fig. a:

1) Place shut---off valves within the circuit to allow servicing;

2) Install a pump system suitable for the flow rate required at
a pressure head equal to the sum of all the pressure drops
(see project data).
Matrix R chillers can be equipped, upon request, with
pumps having performance as indicated in Tab. 8;

3) Install manometers at the chiller inlet/outlet;

4) Install thermometers at the chiller inlet/outlet;

5) Connect the pipes to the chiller by flexible joints to avoid
transmitting vibrations and to balance the thermal expan­sion; proceed in the same way even if the pump set is out­side the chiller;

6) It is useful to include a water pressure switch to give an early
warning of low water pressure;

7) Place a mesh filter at the inlets of the pump and water chiller
(Can be supplied as an optional accessory --- Not fitted);

8) Install, at the highest points in the circuit, apparatus which
allows the bleeding of air and possibly the filling of glycol;

9) Place a drain valve at the lowest point in the circuit and im­mediately at the outlet of the water chiller;

10) Install a water filling set including the following:
a) filling water meter;
b) manometer;
c) non---return valve;
d) air separator;
e) removable supply tube, which must be disconnected

after each charge/top ---up;

2

11) For maximum protection ensure that all tubing exposed to
low outdoor temperatures is fitted with anti ---freeze heaters
and insulated using closed cell synthetic rubber (elasto­mer);

12) The circuit must include an expansion vessel (with safety
valve) of suitable capacity;

13) Connect the lines avoiding stresses on the machine inner
parts.

Note:
If the water chiller is complete with an expansion vessel (sup­plied as an option), check if the capacity is enough, and install
a second vessel in the circuit, if required (see par. 8.4).
Follow the indications in Fig. c for the correct sizing.

Note:
The whole circuit must contain a water volume suitable for the
capacity of the installed chiller. Check if the inertial capacity giv­en by the sum of the hydraulic volume inside the machine (in­cluding the volume of the optional interna tank, if fitted) and the
system volume is sufficient, or possibly install a tank in the circuit.
Follow the indications in Fig. b for the correct sizing.

Note:
The hydraulic circuit must ensure a constant water supply to the
evaporator in every operating condition. Otherwise, the com­pressors may be damaged by repeated returns of liquid refriger­ant on their suction.

Note:
The water flow switch is a compulsory safety component that
must be installed and correctly wired to the Matrix R chillers,
otherwise the guarantee will be invalidated.
It is installed, as standard, on units with the optional on --- board
pump set, and is available as a option for units without pumps
on board: in the latter case the flow switch, if not installed on the
machine, can be installed on the hydraulic circuit by the installer,
butitiscompulsorythatitiswiredtotheelectricpanelterminal
board, as indicated on the wiring diagram.

3.2.2 -- Addition of water and ethylene glycol

Very important:
Add water and ethylene glycol to the circuit with a % depending

on the minimum temperature of the outside air expected at the
installation site. Do not exceed the nominal operating pressure
of the circuit’s components.

Notes:

S To avoid stratification run the circulation pump for at least 30

minutes after adding any glycol.

S After adding water to the hydraulic circuit always discon-

nect the water supply coming from the sanitary supply;

this avoids the danger of glycol entering the sanitary water
system.

S After any topping --- up of the water check the concentration

and add glycol if necessary.

3.2.3 -- Water--gly col mixture

Water---glycol mixtures are used as the thermal carrier fluid in
very cold climates or with temperatures below zero degrees cen­tigrade. Determine the ethylene glycol % which must be added
to the water, with the assistance of T ab. a.

ALWAYS CHARGE THE HYDRAULIC CIRCUIT WITH THE RE­QUIRED GLYCOL % NECESSARY FOR THE MINIMUM AMBI­ENT TEMPERATURE AT THE INSTALLATION SITE. FAILING
TO COMPLY WITH THIS INSTRUCTION SHALL INVALIDATE
THE UNIT WARRANTY.

3.3 --- Connection of the safety valve dis­charge

Safety valves are installed on the high pressure side of the refrig­eration circuit(s): the discharge of these valves must be con­veyed outside through a suitable pipe, having a diameter of at
least that of the valve outlet, without burdening the valve body.
Convey the discharge to areas where the jet cannot harm
people and the surrounding environment.

Fig. b --Inertia tank sizing

The total optimum hydraulic volume of the system where the Matrix R chiller is installed can be calculated by the
following formula:

43 x Rt

V =

where:

--- V=minimum required total water volume expressed in litres

--- Rt=refrigeration capacity expressed in kW

--- Xd=differential band set on the control and expressed in degrees centigrade

Please note that the sum of the hydraulic volume of the Matrix R chiller (Vm) plus the volume of the hydraulic circuit
connected to it (Vpc) must be greater than, or equal to the minimum required total water volume (V). If this condi­tion is not satisfied, it is necessary to install an inertia tank (Vpt, as indicated in the Fig. a) with a volume at least
equal to the following value: Vpt=V ---Vm---Vpc

Fig. c --Sizing of the expansion vessel

The total volume of the expansion vessel is calculated with the following formula:

Xd

C x e

V =

1 --

Pi
Pf

where:

-- - C=quantity of water inside the system expressed in litres

-- - e=water expansion coefficient, with water at 10ûC as a reference

-- - Pi=absolute pressure of initial charging, equivalent to the vessel pre --- charge pressure (typical value

2.5 bara)

-- - Pf=absolute final tolerated pressure, lower than the operating pressure of the safety valve calibration
pressure (typical value 4.0 bara).

Use the values of the water expansion coefficient indicated in the table below:

3.4 --- Electrical connections

1) Before proceeding with the electrical connections, ensure
that:

S all electrical components are undamaged;
S allterminalscrewsaretight;
S the supply voltage and frequency are in accordance with

the rating (with tolerance in accordance with IEC 8--- 6
norms, March 1990)

S the allowed phase to phase variability is 3% maximum

(see Fig. d). Variability in excess of 3% invalidates the
guarantee.

2) Supply cable connections (see Tab. 5):

S Connect the cable to the supply terminals.
S Use appropriately sized 3--- pole cable. An earth wire

must also be connected.

S After having opened the passagein the framework (pre ---

punched knock ---outs) for the supply line entry, restore
the original degree of protection using suitable accesso­ries for the wiring and junction boxes.

Note:
The power supply should never be disconnected, except when
performing maintenance.
Operate (open) the main switch before carrying out any mainte­nance work on electrical components.

Note:
It is forbidden to work on the electrical components without
using insulating platforms, and in the presence of water or fog
or mist.

Note:
The supply to the externalpump assembly must be made before
starting the chiller and must be kept on as long as the chiller is
in use. Incorrect operation will cause the unit to lock ---out be­cause of the internal protections (flow switch intervention).

Note:
The compressors are equipped with an electronic protectionde­vice blocking their start if the phase sequence is not correct, or
stopping their operation if a thermal relay intervenes. This device
is essential for the integrity of the mechanical and electrical com­ponents of the compressors. Reset the standard functions by
isolating this device and removing the causes of the lock---out.

Note:
The chillers are equipped with their own microprocessor control
adjustment. The use of the remote ON ---OFF input (located in
the electric panel terminal board) as a system temperature con­trol element is forbidden.

7) During the unit start---up an inlet water temperature

higher than 20ûC is allowed. Under standard operating
conditions check that the limits indicated in paragraph

2.1 are not exceeded.

8) Check the correct operation of the control and safety de­vices.

9) Check the outlet temperature of the chilled water (check if
the set--- point set on the controller is reached).

10) Check the compressor oil level.

11) With the compressor at full load, check there are no
bubbles visible in the frefrigerant sight glass. If there are any,
charge the unit according to par. 5.

4.3 --- Starting and stopping

ALWAYS ENSURE THAT THE COMPRESSOR OIL HAS BEEN
PREHEATED.
FOR BRIEF STOPPAGES MAINTAIN THE SUPPLY TO THE
CRANKCASE HEATER (IF ANY).

S Start the unit setting the Microprocessor switch ON.
S Stop the unit setting the Microprocessor switch OFF.
S In case of long stops, turn the machine off using the Micro-

processor switch OFF.
In this case the compressor crankcase heaters (if any) re­main powered.

S For seasonal shutdown of the unit operate the main switch

locatedon the main electrical power supply. This will discon­nect the compressor crankcase heaters.

4 --- S t a r t --- U p a n d O p e r a t i o n

4.1 --- Initial check

1) Check all water connections.

2) Open the shut---off valve on the liquid line.

3) Ensure that the intake pressure is higher than 4.0 bar; if this
is not the case, prolong pre --- heating of the compressor (if
possible) and check that the refrigerant shut --- off valve is
properly sealed, see Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16
and Fig. 17.

4) Open all isolating valves and/or water ball valves.

5) In case of climates with temperatures below zero degrees C,
make sure the chilled water circuit is filled with the correct
concentration of water/glycol.

6) Bleed all air out of the chilled water circuit.

7) Verify the water flow rate and its direction.

8) Ensure that the thermal load is sufficient for start---up.

Caution:
The ambient air temperature probe must be positioned in the
shade and protected against the weather.

4 . 2 --- F i r s t s t a r t --- u p

(or after a long stop)

Operate as follows:

1) At least 8 hours before the start ---up, power the crank-

case heaters (if any, see point 4) by setting the main iso­lator switch ON. Make sure the auxiliary circuit has b een
powered and check the operation (a fault due to an in­correct procedure will invalidate the compressor guar­antee).

2) Open the valves of the refrigeration circuit that had been
closed before the initial check.

3) Check the machinery supplying the thermal load connected
with the unit and start the system pump(s).

4) MAKE SURE THE COMPRESSOR OIL HAS BEEN HEATED
FOR AT LEAST 8 HOURS; start the unit only then. In the
units not equipped with crankcase heaters (Chillers for sum­mer operation only, without modulating fan speed control),
the start must be carried out in the warm season only (exter­nal T > 15ûC), and thus oil pre---heating is not necessary.

5) Make sure the fans rotate in the correct direction (anticlock­wise): check the electrical connections, if necessary .

6) Make sure the pumps rotate in the correct direction.

4.4 --- Chillers serving special plants

The units are capable of cooling a water ---glycol mixture to tem­peratures close to 0ûC without the need for significant modifica­tions. In the case of modification, the set values of the safety and
control components must also be changed. This can be carried
out in the factory (at the time of testing) or at the time of installa­tion, only by qualified and authorised personnel.

4 . 5 --- F r e e c o o l i n g

The “freecooling” is a system of pre ---cooling and/or cooling the
water/glycol mixture using ambient air when the latter is at a tem­perature below the return mixture temperature. If the outside
temperature is sufficiently low to dissipate the entire heat load,
the refrigeration compressors automatically switch off, and the
mixture’s temperature is controlled by the fan speed adjust­ment.
If the mixture temperature is too high for freecooling, the com­pressors will operate as long as necessary to ensure the correct
water/glycol mixture temperature.

4.6 --- Microprocessor control

Consult the ”Microface and Hiromatic” Service Manual.

5 --- R e f r i g e r a n t a n d O i l C h a r g e

All work on pipes or components of the refrigerating circuit un­der pressure must be exclusively carried out by qualified staff,
competent in such works.

5 . 1 --- R e f r i g e r a n t c h a r g e

WHILST REPAIRING THE REFRIGERATING CIRCUIT RE­COVER ALL THE REFRIGERANT IN A CONTAINER: DO NOT
ALLOW IT TO ESCAPE. NEVER USE THE COMPRESSOR
FOR THE SYSTEM VACUUM (THIS INVALIDATES THE
WARRANTY).

S The unit is delivered charged according to the Tab. 2.
Warning for the refrigerant charge:

S Ensure there are no refrigerant leaks.
S Check the refrigerant type in the refrigeration circuit: a unit

originally charged by the manufacturer with R407C cannot
be charged with R22 and vice versa; possibly apply to the
Technical Support Department.

5

S Charge with the compressor in operation, connecting the

cylinder with the charge connector after the thermostatic ex­pansion valve.
Flush the connection pipe between the cylinder and the
charging point; tighten the seal joint and then start charging
the unit. It is imperative that the cylinder is weighed both be­fore and after the operation.

S For the units with R407C the refrigerant charge must be

made exclusively with liquid refrigerant.

S Charge the unit until the bubbles in the sight glass have dis-

appeared and the working conditions of the entire refrigera­tion circuit have returned to normal (sub---cooling and su­perheating within the limits indicated below).

S Measure the superheating as follows:

1) Detect the temperature on the suction line, close to the
bulb of the thermostatic expansion valve, using a contact
thermometer.

2) Connect a pressure gauge (by max. a 30 --- cm pipe) with
the Schraeder connection and read the corresponding
saturated evaporating temperature.

3) The superheating is the difference between the two
readings.

4) For the units with R407C refer to the pressure gauge
scale indicated with the initials D.P. (Dew Point)

S Verify that the superheating is 5ûC --- 8 ûC.
S Measure the sub---cooling as follows:

1) Detect the temperature on the liquid line using a contact
thermometer.

2) Connect a pressure gauge (by max. a 30 --- cm pipe) with
the Schraeder connection on the liquid line and read the
corresponding saturated condensing temperature.

3) The sub --- cooling is the difference between the two read­ings.

4) For the units with R407C refer to the pressure gauge
scale indicated with the initials B.P. (Bubble Point)

S Verify that at the condenser outlet, sub --- cooling is 3ûC ---

5ûC.

IT IS IMPORTANT TO CARRY OUT CHARGING CORRECTLY.
An excess of refrigerant causes an increase in sub --- cooling and

consequent operating difficulties in the hot season; a shortage
of charge generates an increase in superheating and possible
compressor stoppages. Whenever work is carried out on the
unit, ensure afterwards that the working conditions are correct,
checking sub---cooling and superheating.

5 . 2 --- O i l c h a r g e

Contact the TechnicalSupport Department for the specifications
of the oil to be used for topping up; the oil changes according to
thetypeofusedrefrigerant.

NEVER MIX DIFFERENT OILS TOGETHER. CLEAN THE PIP­ING COMPLETELY BEFORE CHANGING THE TYPE OF OIL
USED.

TOP ---UPS OF UP TO 20---30% OF THE TOTAL AMOUNT OF
OIL CONTAINED IN THE COMPRESSOR CRANKCASE ARE
PERMITTED; FOR LARGER PERCENTAGES CONTACT THE
TECHNICAL SUPPORT DEPARTMENT.

5.2.1 -- Procedure for oil topping--up

If there has been any loss of oil then this must be topped up as
follows:

1) T ake a clean, dry, transparent container (with volume cal­ibrations) and fill it with at least twice the amount of oil re­quired.

2) Isolate the compressor by closing the cock on the liquid line.

3) Connect to the fittings on the compressor body (Schraeder
valves) and empty it of refrigerant until atmospheric pres­sure (1 bar) is reached.

4) Using a pipe, connect the oil containerto the oil service fitting
on the lower part of the compressor.

5) Open the oil service cock, lifting the container, so that the oil
flows by gravity.

6) Charge the required quantity of oil (make sure the tube al­ways remains below the oil level in the container).

7) Stop the oil flow by closing the oil service fitting, open the
shut---off cock on the refrigerating circuit and restore the
drained refrigerant charge.

6.1 --- Setting thermostatic expansion
valve

THIS OPERATION MUST BE PERFORMED BY AN EXPERI­ENCED REFRIGERATION TECHNICIAN.
Before beginning this adjustment be sure that the refrigerant

charge is correct, checking the the sub --- cooling (3ûC---5ûC, as

specified in par. 5.1).
The valve has already been factory--- set and should be reset
when the superheating is not between 5ûC --- 8 ûC, as follows:

1) Important:

Ensure that the instructions in par.5.1 have been carried out.

2) Allow the compressor to operate for 15 mins.

3) Measure the superheating as follows:

a) Connect a manometer to the Schraeder connection lo-

cated on the evaporator outlet tube, and read the mano­metric temperature on the scale for the refrigerant used
(for the units with R407C refer to the pressure gauge
scale indicated with the initials D.P. = Dew Point).

b) Using a contact thermometer, measure the temperature

on the tube coming out of the evaporator, next to the
socket used for the manometer.

7 --- Maintenance

The Maintenance Programme below must be carried out by a
qualified technician, preferably working under a maintenance
contract.

Before any intervention on the unit or accessing the inner com­ponents (removing the outer panels), always ensure the ma­chine is switched off. If the panels are removed (fans compart­ment) wait for the fan(s) to come to a complete stop before
accessing the compartment; if the front panels are removed (on
mod. 004 ---016) or the front lower panels (on mod. 017 --- 032),
pay special attention when working near the compressor upper
part and the discharge line: they are very hot; possibly wait for
them to cool. Be very careful when operating close to the finned
coils, as the fins are very sharp. Do not remove the fan protection
grille before electrically isolating the whole machine. Do not in­sert foreign matter through the fan protection grille. After the
maintenance interventions, always close the unit with the suit­able panels, fastened by the tightening system.

c) The superheating is the difference between the two

readings (b ---a).

4) The superheating must be 5ûC---8ûC; if not, set the expan-

sion valve as follows:
a) Remove the protective cover;
b) Turn the adjustment screw to return to the optimum val-

ues, tightening it in a clockwise direction to increase the
superheating, or slackening it to reduce the superheat-

ing.
c) Wait about 10 minutes;
d) Measure the superheating and repeat the operation if

necessary.

N.B:
If the superheating is too low, there is a risk of poor lubrication

and consequent breakage of the compressor as a result of pres­sure shock.
If the superheating is too high the output of the system is limited
and the compressor overheats.

7.1 --- Spare parts

The use of original spare parts is recommended.
When placing an order refer to the ”Component List” enclosed
with the machine and quote the unit model no. and serial no.

7.2 --- Dismantling the unit

The machine has been designed and built to ensure continuous
operation.
The working life of some of the main components, such as the
fans and the compressors, depends on the maintenance that
they receive.
If the unit has to be dismantled, the job must be done by skilled
refrigeration technicians.
The refrigerant and the lubricating oil in the circuit must be dis­posedofinconformitywiththelawsinforceinyourcountry.

8 . 1 --- P u m p s e t

On mod. 004 --- 016 the centrifugal pump units are direct driven,
with close-- -coupled motors and a single shaft; the induction mo­tor has 2 poles with IP 54 protection and class F insulation.

The materials used for the pump main components are:
S Pump body in plastic material PA 6.6 (cast iron in all high

pressure freecooling versions and on model 016 in the Chil­ler high head pressure version and Superchiller standard
head pressure version);

S Impeller in in plastic material PPO (stainless steel in all high

pressure freecooling versions and on model 016 in the Chil­ler high head pressure version and Superchiller standard
head pressure version);

S Stainless steel shaft;
S Graphite impregnated ceramic mechanical seal (EPDM in

all high pressure freecooling versions and on model 016 in
the Chiller high head pressure version and Superchiller
standard head pressure version), suitable for the use of mix­tures containing ethylene glycol.

The pump units have been chosen and sized to operate within
specific limits, namely:

S Water / ethylene glycol mixtures up to 65% / 35% by weight;
S Temperatures of the standard pumped fluid not lower than

4°C.

The hydraulic circuitincludes,for each pump, a suctionshut---off
valve and a delivery check valve if two pumps are installed, or
suction and delivery shut---off valves if a single pump is installed.

On mod. 017 --- 032 the centrifugal pump units are direct driven,
with close-- -coupled motors and a single shaft; the induction mo­tor has 2 poles with IP 55 protection and class F insulation.

Pump casings and impellers are in cast iron EN -- -GJL 200, shafts
are in stainless steel, the shaft seal is a unbalanced, mechanical
shaft seal with dimensions according to DIN 24 960 and assem­bly length according to EN 12 756, brass neck ring permits ideal
conditions for the use of water mixtures containing ethylene gly­col. The pump housing, the motor stool and the motor stator
housing are electrocoated.

The pump units have been chosen and sized to operate within
specific limits, namely:

S Water / ethylene glycol mixtures up to 65% / 35% by weight;
S Temperatures of the standard pumped fluid not lower than

4°C.

The motor stool forms connection between the pump housing
and the motor, and is equipped with a manual air vent screw for
venting of the pump housing and the shaft seal chamber. It is
very important to carry out this operation as the circulation of liq­uid through the duct of the air vent screw ensures lubrication and
cooling of the shaft seal.

Between the outlets of the two chambers and the discharge
flange, twin --- head pumps have a non --- return flap valve in
EPDM rubber. The flap is opened by the flow of the pumped liq­uid and cuts off the port of the idle pump chamber.

In the electrical panel there are, for all the models of pumps, au­tomatic circuit breakers for each pump; the microprocessor con­trol manages the operating rotation between the two pumps and
start---up of the stand ---by pump if the primary pump fails.

For the technical features of the pumps and the hydraulic sche­matic see Tab. 8, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 21 and
Fig. 22.

8.2 --- Water chiller with partial heat
recovery (20%)

This option enables the recovery of up to 20% of the heat normal­ly rejected by the condensers. The system does not require any
adjustment and is made up of plate heat exchangers installed
on each circuit before the condenser. The exchangers are pro-

tected by a suitable anti --- frost heater that operates when the sy­stem is stopped. It is recommended that a safety valve be
installedin the hydraulic circuit to avoid hazards due to overpres­sures, if there is no water flow through the recuperator.

The water temperature at the recuperator inlet (in stable operat­ing conditions) must be in the range of 25ûC --- 45 ûC, with an out­let differential of between 3.5ûC --- 8 ûC.

8.3 --- Water chiller with total heat recovery
(100%)

All heat discharged by the unit to the condenser is recovered.
The system includes an additional refrigerating circuit made up
of a three --- way solenoid valve, supplying --- in case of hot water
demand --- a plate exchanger, usually by --- passed and sized so
as to discharge all condensing heat (also installed before the
finned air condenser in series with it); a check valve, a liquid re­ceiver at the exit of the finned air condenser working as storage
for the needed additional refrigerant charge (see refrigerating
scheme). The recuperator is insulated with closed cell polyure­thane and is equipped with heaters activated when the recuper­ator is deactivated to prevent frost in winter with the system
stopped or not perfectly drained.
The operation in total recovery mode is enabled by an external
contact. The Microface control will simultaneously suit the fan
speed changing the fan speed setpoint differently from the stan­dard operation without recovery (practically slowing the fans
down till they switch off); anyway , the operation in recovery
mode is enabled also without load at the users. Indeed, if the us­ers do not demand heat, the water flowing to the condenser
reaches a temperature that does not enable the total condensa­tion of the compressed gas, and the remaining portion of the
phase change can thus take place in finned coil without inter­rupting the recovery process through the intervention of the ma­chine safety devices.
If the plate exchanger is supplied with too cold water, or if the sy­stem is not preset by the installation technician with a three or
two---way proportional adjustment valve for the exchanger by­pass (indispensable for cold starts, see following “Recom­mended hydraulic circuit” ), the condensing pressure tends to
decrease too much; a prolonged condition of low condensing
temperature below the safety threshold leads the Microface mi­croprocessor control to disable the heat recovery, protecting the
system from any possible malfunctioning.

8.4 --- Hydraulic circuit accessories

Made up of an expansion vessel (pre --- charged at 1.5 bar, max.
operating pressure 10 bar) and a safety valve, set at 5 bar. Their
position in the hydraulic circuit is illustrated in Fig. 18, Fig. 19,
Fig. 20, Fig. 21, Fig. 21 and Fig. 22.

S Expansion vessel volume:

-- - 8 litres for all 004 ---016 units,

-- - 12 litres for all 017 ---032 units.

It is recommended that the total required expansion vessel ca­pacity is always checked, depending on the unit’s internal hy­draulicvolume(withthevolumeofthebuffertank,ifinstalled),
the user circuit volume, the glycol percentage in the mixture, and
the expected maximum temperature variation of the mixture.

The water flow switch is a compulsory device protecting the unit.
It is installed, as standard, on units with the optional on --- board
pump set, and is available as a option for units without pumps

8

on board: in the latter case the flow switch, if not installed on the
machine, must be installed on the hydraulic circuit by the install­er and wired to the electric panel terminal board, as indicated on
the wiring diagram.

8.5--- Waterchillerwithinertiatank

The machine can be supplied complete with a buffer tank; it per­forms the inertial stabilizer function, for better compressor op­eration, summed up in the following two points:

S it reduces the frequency of the compressor peaks, which is

higher the lower the system thermal inertia, improving their
performance;

S it naturally eliminates the operational problems caused by

sudden load variations (shown by variations of the chilled
water temperature).

The buffer tank is supplied insulated, with a drain valve, vent
valve and connection for immersion electric heaters; maximum
operating pressure 6 bar.

Builtincarbonsteelandcoatedwithanti---condensationinsula­tion. It can be installed in all MATRIX R 004 --- 016 versions inside
the coil compartment, while on mod. 017 - --032 it is installed in­side a cabinet which can be supplied either already connected
to the unit (mechanically and hydraulically jointed to it) or loose
(completely separate from the unit).
