Main functions
•
••
•Water temperature control:
- Either on the evaporator (chilled water control).
- Or on the condenser (hot water control).
•Two types of control are possible :
- Gap on the water return.
- PIDT on the water outlet.
- Remote modification of the setting point via a
remote control (optional).
- Variation of the setting point (heating or cooling) as
a function of the external temperature.
- Control of the operating parameters.
- Faults diagnosis.
- Possibility of control by remote processing.
- Possibility of an interface module carrying forward
the fault or operating modes.
- Fault memorization in case of power cut.
- Possibility to control:
•
The number of compressors starts.
•
The number of compressors operating hours in
order to balance the operating periods.
For detailed description, refer to maintenance
brochure MRS 1-4.1
All the packaged units are checked and tested in the
factory and receive a load of R22 or R407C for
standard operation.
On receiving the material, check the unit. In case of
deterioration, advise the shipping agent by
registered mail.
To lift the unit, fix the lifting lugs designed for this
purpose. The lugs must be kept apart by using cross
bars in order to avoid damaging the casing or the
electrical panel.
These units are positioned only indoor for the
packaged versions (LR, LRP, LRT, LRN).
The unit must be easily accessable to allow
maintenance and servicing operations. Plan a free
space around the unit (1 m) and ensure a free
circulation of air on the outdoor condenser. The
unit(s) must be perfectly level.

Connections
• Water connections:
In all cases, the characteristics of piping must comply with
the operating conditions.
For the connections, respect the flow direction mentioned
on the unit. The piping diameter is not necessarily the
same as the one planned on the exchangers.
• Condenser water connections :
The condensation can be made either through
• Water-to-waste (city water).
• Water cooled by a cooling tower.
• Water cooled by an air cooler.
It is necessary to plan on the piping circuit:
• 2 stop valves to isolate the condenser.
• 1 drain cock with valves to empty the circuit.
• 2 drain cocks with valves for chemical cleaning of the
condenser.
• Chilled water piping connection :
It is necessary to plan on the piping circuit:
• 2 stop valves to isolate the evaporator.
• Accessories required for all hydraulic circuits: air vents,
drain cocks at low points, expansion vessel...
The piping will be carefully insulated to avoid
condensation and heat losses.
NOTE : Max. working pressure on water side : 10 bars.
• Electrical connections:
In all cases, refer to the diagram enclosed with the unit.
The connections to be made are as follows :
• Panel power supply :
400V-3ph- 50 Hz + Earth or 230 V -3ph- 50 Hz + Earth
• Control circuit supply :
230V-1 ph-50Hz
• Wiring of the external safety devices and of the
automatic control (clock control).
Compressors servo control to the operation of the chilled
water pump, condensing water pump, cooling tower
ventilation, etc.
• Protection of power circuit electrical supply lines : fused
isolator (type "aM") or motor starter (to be supplied by the
installer).
The power circuit breakers have a 10 KA cutting capacity.
If this value is not sufficient, HPC (high capacity devices)
must be installed upstream from the circuit breakers.
• Refrigerant connections:
Split water chillers with separate air cooled condenser
LRN.
Once the unit is in position, make the refrigerant
connections between the indoor and outdoor assemblies
(air cooled condenser).
The piping network must be carefully designed.
Plan the shortest possible distance (15 m max. length of
piping, with a 6 m change in level).
Works performed must comply with good engineering
practice. Avoid use of contaminants, all brazings must be
made under nitrogen R scanning.

Case of units without condenser, type LRN.
These units can be connected either to an air-cooled condenser
or to a water cooled condenser.
Important : In the case of a connection to an air-cooled
condenser, the fans contactors and protection devices as well as
the condensing pressure control system are to be supplied by the
installer.
Operation
•
••
•Starting sequence:
- As soon as the electrical connection of the panel has been
made, the crankcase heater is live. Leave the heater live for a few
hours before starting the compressor (6 hours).
- Press key M /A (ref. ) located on the MRS-4.display card to
start the unit.
The start will only occur after 2 min, time required to scan the unit
safety devices. If no anomaly is detected, the unit will go into
operation.
- Automatic re-starting of the unit after electrical network
accidental cuts.
- All the safety devices of the unit are controlled by the MRS -4.
electronic card. If a safety device trips, the fault must be located,
reset the safety device if necessary, then release the fault with
the "RESET" (ref.5) key on the display card.
When the minimum time period required by the anti-short cycling
is over, the unit can start again
- The equalization of the compressors operating periods is
automatically controlled by the electronic module.
It is also possible to control the stop of each compressor.
NOTE : During the months when the installation is utilized, the
electrical panel must be permanently live in order to keep the
crankcase heaters supplied while the compressors stop.
•
••
•
Regulation:
- The operation of compressors is controlled by the electronic
module as a function of a chilled or hot water discharge or return
temperature, according to the type of unit.
- Each compressor motor is protected electrically by an integrated
electronic device.

Double condenser units.
•
••
•
WATER + WATER : Version LRT
The CIATCOOLER double condenser water chillers are
designed so as to transfer and recover the calories which are
normally utilized and rejected by the traditional units.
In a standard installation where cooling is required all year,
the calories produced by the units are usually discharged by
the air cooled condenser or by a cooling tower or a dry cooler
via a water cooled condenser.
It is possible to use the condensing gas in another condenser
to contribute to the heating process.'
In this case, the condensing gas participates directly to an
energy saving instead of being cooled without profit in the
discharge condenser.
A water cooled condenser will be used as a recovery
condenser. Water, as intermediary fluid, is easy to carry, the
on-site installation is therefore facilitated.
•
••
•
Design :
Water cooled condenser + air cooled condenser
The discharge gas passing first through the water cooled
condenser, the calories produced by the unit can be totally
recovered. The losses caused by desuperheating are
insignificant, the external surface of a water cooled condenser
being very small compared to the one of an air cooled
condenser.
In the case where the recovery circuit does not evacuate any
of the calories produced and where the circulation pump is
stopped, the circuit stagnant water can rise around 90 °C.
The water circuit being under pressure, the boiling point is
delayed. The water circuit being looped, there is no risk of
scaling, except if the circuit requires a frequent filling.
This solution does necessitate a liquid reservoir in order to
prevent an unpriming of the liquid line, therefore a faulty
supply of the expansion valve.
•
••
•
Hydraulic circuit:
- Heating circuit connection (hot water). It is necessary to
install on the heating circuit:
- 2 stop valves to permit isolation of the water-cooled
condenser.
- The accessories required for all hydraulic circuits : air vents,
drains at low points, expansion vessel...
• Operation :
In summer or mid season, above + 12 °C and when not using
hot water, it is possible to operate the air-cooled condenser
fans in forced run mode by using a switch, connected
between the 2 terminals and positioned on the electrical panel
terminal box; this will maintain a lower condensing pressure.
For the other cases, below +12 °C and with production of hot
water, it is necessary to maintain the condensing pressure at
a correct level to:
- permit a correct supply of the expansion valve
-produce hot water at the desired temperature
To meet these 2 conditions, the condensing pressure will be
kept at a higher value than the hot water outlet temperature.
This condensing pressure will be maintained by HP
pressostats operating in cascade on the condenser fans.

The operation will be as follows:
• In the case where the recovery circuit evacuates all of the
calories produced, the fans will be stopped, the condensing
pressure will be maintained by discharging
the calories on the water circuit.
• In the case where the recovery circuit evacuates only part of
or none of the calories produced, the pressure in the
refrigerant circuit rises, the air-cooled condenser wilt be
solicited.
Important : The recovery output on the water-cooled
condenser will be controlled in permanence by a regulation
device located on the water circuit to be mounted on site
externally to the unit at the time of installation.
Attention : The unit is designed for all year around operation.
The electrical panel must be permanently live. All precautions
are to be taken to avoid an accidental cut of the network. The
pipings external to the unit are to be protected from freezing.
Drain the exchangers when there is a risk of freezing.
•
••
•
Design :
Double water – cooled condenser.
Instead of having one water-cooled condenser + one air-
cooled condenser, we have only one 2 circuits condenser on
the water side:
• 1 circuit for the recovery of calories on the heating circuit,
• 1 circuit for the discharge of calories on a cooling tower or
on a dry-cooler.
This design does not require the addition of a liquid reservoir.
The units with double water + air cooled condensers as well
as the double water condensers ones permit either a total or
a partial recovery.

Works before commissioning
- For all the units, in order to avoid transmission of vibrations
to the building structure we advise to position antivibration
mounts between the frames of the units and the ground, and
flexible connectors on the hydraulic circuits.
- For units requiring a refrigerant connection, extra flexible
connections on the refrigerant circuits will be planned.
LR, LRP, LRT, LRN :
- Electrical connections.
- Hydraulic connections.
LRN:
- Refrigerant connections.
- Pressure tests for the installation
- Leaks detection.
- Positioning of a dessicant cartridge.
- Purging,
- Load of refrigerant.
Attention, for the pressure test :
- Introduce a R22 or R407C and nitrogen R mixing in the
circuit up to a 10 bar max. pressure.
- Always use a manual expansion valve between the
nitrogen bottle and the refrigerant circuit.
- Never use oxygene or acetylene instead of nitrogen : a
violent explosion could result.
Attention, for the vacuum test:
-Never use the compressor as a vacuum pump, it has
not been designed for that purpose. Use a vaccum
pump able to create a 1 mm mercury vacuum.
Check before commissioning
- Check that the liquid departure and discharge valves are
open.
- Open the water circuit valves and make sure that the water
does circulate in the chiller while the pump is in operation.
- Check the flow switch operation and the chilled water pump
servo-control.
- Adjust the setting on the MRS 1 -4.1 front face
- Check that all the electrical terminals are tightened
- Make sure that the network voltage does correspond to the
voltage of the unit and that the value remains within the
correct limits (± 5% in relation to the 230 V or 400 V nominal
voltages).
- Leave the compressor crankcase heater live a few hours
before operating the compressor (6 hours).

Once the above checks have been made :
- Press the M/A key (ref. 1 - page 2).
- The units must start after a 2 min delay.
- The compressors start in cascade.
LRN:
- Make sure the installation is loaded with refrigerant.
- Close the liquid departure valve.
- Connect, without tightening, the refrigerant bottle on the
loading valve.
- Open temporarily the refrigerant bottle valve to vacuum the
connector. Re-tighten the connection.
- Open the refrigerant bottle tap.
- Keep the low pressure pressostat closed.
- Put the switch on live.
- Press the key M/A, the units should start after a 2 min delay.
- The compressors start in cascade.
- Complement the refrigerant load from time to time, close the
tap of the refrigerant bottle and open the liquid departure tap.
- Check the fluid outlet on the sight glass, add small quantities
of loading fluid to complement.
- Verify that the load is correct by checking the overheating and
sub-cooling, remove the loading devices: ensure that the
refrigerant bottle tap is closed correctly and that the liquid
departure valve is completely open (rear position).
•
••
•Check immediately that:
- The discharge is heating (hot to the touch).
- The absorbed voltage is normal (see table and rated value on
the compressors).
- The operation of all the safety devices (see table page 15 for
setting values).
Note : When starting a water chiller, numerous problems are
caused by a suction pressure too low and a condensing
pressure too high.
The main causes are the following :
•
••
•
Suction pressure too low :
- Presence of air in the chilled water circuit.
- Chilled water pump too low, insufficient flow.
- Chilled water pump does not operate normally (rotates in the
wrong direction).
-Chilled water temperature too low, lack of heating load.
•
••
•Condensing pressure too high :
- Ventilation of the condenser is not correct (obstacles at the
intake or on the discharge, fans rotate in the wrong direction).
- Intake air is too warm (recycling).

Operating limits
• Load restriction :
When starting the unit, the water temperature at the
evaporator inlet can reach 20 °C max.. In order to avoid the
cuts in high pressure, the electronic module unloads the last
stage of each circuit.
When the water temperature diminishes, the full load
operation is authorised.
• Freezing limit:
The antifreeze setting limit adjustment is achieved by keys
designed to this effect on the MRS 1-4.1 relay card.
The temperature difference between the chilled water outlet
and the antifreeze setting is 3 °C minimum.
When the regulation is made on the chilled water inlet
temperature, the water inlet/outlet difference must be taken
into account so as to determine the antifreeze setting.
The control takes place on the chilled water outlet
temperature. As soon as the sensor detects a water outlet
temperature equal to the antifreeze setting
→
the unit stops
and the fault is displayed on the corresponding LED.
NOTE : Whatever the mode of operation (heating or cooling),
when the chilled water temperature descends 2 °C above the
antifreeze setting, the MRS 1-4.1 puts the unit in reduction of
power (re-setting at 2 °C+ 1,5 °C above the antifreeze
setting).
• Modification of the setting point:
The regulation is made either on the inlet temperature or on
the chilled water outlet temperature.
To lower the unit setting point, proceed as follows :
1) Modification of the antifreeze setting.
2) Setting of the new water inlet or outlet value, taking into
account the 3 °C minimum temperature difference.
The MRS1-4.1 prevents the setting adjustment for a
temperature difference lower than 3 °C.
