Transportation and handling
The courier is always liable for any damage during transit to the goods that have been entrusted to the same.
Before preparing the unit for installation and commissioning, a thorough visual inspection must therefore be
carried out to check that the packaging is intact and that the unit presents no visible damage nor oil or refrigerant
leak. Also ensure that the units correspond to the order that was placed.
Any damage or complaints should be reported to Euroklimat and to the carrier by recorded delivery letter within 8
days from receiving the goods.
Should one or more components be damaged, do not proceed with starting up the unit and inform Euroklimat of
the problem, agreeing with the latter the actions to be taken.
Preferably remove the packaging at the actual place of installation.
Internal handling must be carried out with the utmost care, without using unit components as handholds. To avoid
damage it is essential when moving the units that they always remain in the position envisaged for their operation.
Do not leave packaged units in places exposed to strong sunlight, since the internal temperature could reach safety
device tripping values.
The water circuit must be fully drained before handling the unit in any way whatsoever.
Lifting should preferably be carried out with a lift truck. Use a spreader beam if belts or ropes are used for slinging,
making sure that there is no pressure on the upper edges of the units or the packaging.
Example of lifting with a lift truck:
Insert protection for the outer structure of the unit, for example a sheet of cardboard or polystyrene (A).
Make sure that the forks of the lift truck project at least 100 mm (B) from the other side of the unit.

Unit positioning
The customer should check that the strength of the supporting surface is suitable for the weight of the unit.
It is unnecessary to fix the unit to the floor for correct operation.
If the floor is rough, to ensure a level surface and prevent even the smallest of vibrations, it is advisable to insert a
continuous rubber sheet the same size as the base supports.
It is also advisable to make sure the unit is level. Should this be impossible or difficult to accomplish, the unit must not tilt
more than 0.5°.
For a correct operation and for maintenance interventions respect the free space around
the unit (see figure).
WARNING:
The gas content into the R290 is flammable.
The chiller should be installed only outside and away
from any heat source and sunlight protected.
Max Temp = +45.0 ° C (storage)

Description of operation of the machine
Liquid chillers of the series "EKE-R290" are designed to meet the needs of air conditioning systems or industrial
processes, requiring the production of chilled water.
The variety of models and power, can cover a wide range of applications.
The production of cold water occurs through the refrigerant cycle, as shown in the following diagram:
The refrigeration system consists of a compressor, a condenser, an expansion valve, and an evaporator.
The use of the suction gas heat exchanger (SGHX) is a special feature of EKE-R290 EUROKLIMAT range.
Description of cycle process
The suction gas (1) is compressed and discharged into
the discharge line (2). The discharge line leads the
refrigerant to the inlet of the condenser (3). The
condensed and subcooled refrigerant in the
condenser outlet (4) is either lead to the liquid inlet of
the suction gas heat exchanger (SGHX). The exit
condition (5) will be different from condition (4). From
the expansion valve outlet (6) the refrigerant is lead
to the evaporator. The evaporated and superheated
refrigerant in the evaporator outlet (7) is lead through
the suction line, either to the gas side inlet of the
SGHX, if this has been selected, or to the compressor
inlet (1). Thanks to SGHX the exit condition (8) will be
different from condition (1).
In the suction line the gas may experience both a
pressure drop and a temperature increase. In the
discharge line the gas may experience a pressure drop
only.

All the units are fitted with a safety valve on the water side. The purpose of this valve is to drain to the outside through a
pipe. It is therefore advisable to connect the valve to a pipe of at least the same diameter in order to convey any
discharge from the valve to the outside. This pipe must be located so that the discharge can cause no damage to property
or injury to persons. The pipe must also be suitably supported so that it does not weigh on the valve.
The installation must be in conformity with current safety regulations.
If units are not used during the winter, fully drain the water system of all units installed outdoors. If operation is
envisaged also in this period or in any case with low ambient temperatures, antifreeze mixtures must be used.
With indoor installations, drainage is in any case necessary when the room temperature falls to below 0°C.
For installation diagrams, refer to the examples given in the section “Installation”.
Always fit ball shutoff valves on the water inlet and outlet.
If it is possible that the water may be dirty, also install a “Y” filter on the water inlet.
For more information please contact the After Sales Department of Euroklimat S.p.A..
If the USER needs to disassemble some parts for which the procedure is not given in this manual, it is
indispensable to request permission and the relevant procedure from “Euroklimat”.
Any assembly/disassembly carried out by the USER that is not contemplated in this manual or authorised by

Start-up procedure
Filling the water circuit Authorised personnel: Maintenance mechanic
Before to start up the unit it’s necessary to fill the water circuit
Water / mixture temperature for filling = MAX. 25°C
Open the air valve (and connect it to a drainage well using a plastic hose) so that any air present in the circuit will be
discharged during filling, which will consequently be quicker. Take care that any water that sprays out when the circuit
has been filled does not create a hazardous situation. If there are any points in the system circuit higher than the unit air
valve, another air valve, if possible automatic, must be inserted at the highest point to ensure complete filling of the
circuit.
- Connect the unit water outlet tap to the mains water system.
- Open the mains water supply to fill the circuit.
- When water comes out of the hose connected to the air valve, the circuit has been filled.
CAUTION
Once the system has been filled and after having made the pump circulate
for some time, check for residual air. If there is still air present, the circuit
must be bled and filled up with the missing water. With the system
inoperative, it is also necessary to ensure that the pressure in the circuit is
only just above zero. This indication is visible through the pressure gauge
mounted on the unit.
Warning: WHEN THE FILLING IS FINISHED YOU HAVE TO CLOSE THE WATER
DRAIN TO AVOID THAT THE PRESSURE IN THE CIRCUIT INCREASES.
(Not for versions with closed vessel, which is equipped with pressure reducing
valve).
Filling with antifreeze mixture
If it is necessary to use antifreeze mixtures, filling must be carried out with a solution prepared according to the water
temperature:
Mixture / Outside
temperature % ethylene glycol
+20 °C -
+15 °C -
+10 °C 5% (suggested)
+5 °C 10%
0 °C 15%
-5 °C 25%
-10°C 30%
If a ready solution is unavailable, it must be prepared in a container to be connected to the unit water outlet, as
described above. Closed or open tank filling kits are available on request by the customer.
For more information please contact the After Sales Department of Euroklimat S.p.A..

STARTING AND USE
The professionals involved in this
section are:
The Operator, who must always
operate with the fixed guards
correctly mounted and check that
under no circumstances have they
been tampered with.
The Maintenance men, who must
always operate with the unit at a
standstill and after having carried
out the required operations, check
that all the protective devices are
correctly remounted, closed and
in proper working order.
The Safety officer, who must
check that the Operator and the
Maintenance men have received
all the necessary information as
per this manual. He will check in
particular that all the fixed guards
have been correctly mounted, are
in proper working order and have
not been tampered with.
Unit control devices
Door interlock
Microprocessor for unit start and
control
Compressor ON/OFF switch
1. Check the compressor ON/OFF switch is off (position “0”).
2. Turn the door interlock in position “1” (ON).
Warning
When switching on for the first time, the oil must be preheated in the models indicated in
the table. This requirement is also identified on the unit by the following plate. The
procedure is carried out when starting the unit for the first time and whenever the unit
has been switched off by means of the power on/off switch for longer than 4 hours. Do not
proceed with other operations until this procedure has been completed, otherwise the
compressors could be damaged.
Euroklimat S.p.A. declines every responsibility for eventual damages that can directly or
indirectly derive to persons or things in consequence to the lacked observance the
present instructions.

[25]
Put to ON. On the microprocessor, press the button for 5 seconds.
The water pump (if present) starts.
When starting for the first time, check the correct direction of rotation of the
pump. To do this, close the ball valve fitted at the unit water inlet and outlet,
as described in the paragraph “water connections”.
Fully open the by-pass. Using the pressure gauge on the unit check that the
circuit is pressurised. If it is not, switch off the unit using the power on/off
switch and invert the connection phases at the on/off switch input, paying
attention to the possible presence of current. Then check the working
pressure with the pressure gauge on the unit.
Make sure that there are no automatic valves, which could reduce the flow,
and that the circuit shutoff valves are fully open. Use the handle of the by-pass
valve to adjust the pressure until the liquid pressure gauge indicator is in the
appropriate sector.
This sector is specific for each type of pump (standard or uprated) and for each
model. The table below indicates the operating range for each combination.

COOLING mode
If the temperature of the water (see value of the display) is lower than r01 (Summer/cooling set point) value (default is
7.0°C), the compressor is OFF.
The water pump (if present) runs.
If the temperature of the water (see value of the display) is higher than r01 + r02 (differential) value (default is 3.0°C), the
compressor is ON and the cooling starts and runs valore di set point r01.
FOR SET POINT MODIFICATION (r01 and/or r03) SEE CHAPTER “CONTROL PANEL”
Check of cooling
The chiller normally works with a difference of approx. 5° between the evaporator water inlet and outlet (with by-pass
valve closed), which may be checked with contact thermometers.
Check for any alarm warnings.
Checking the safety devices
The unit, connected as described in the section “Commissioning” under the paragraph “Connection of Safety Devices”,
must guarantee safety functions in an emergency. The emergency stop button must therefore be pressed to check that
all the motors stop. If operation is correct, reset the emergency button and continue with the switching on procedure as
described previously.
Compressor START/STOP
This switch is used to cut out compressor operation and allow the unit to work with the pump only whenever working
conditions so require.
Under normal working conditions compressor starting and stopping is automatic and is controlled entirely by the
microprocessor.
Position “0”: Compressor off
Position “1”: Compressor on
The unit is equipped with a safety that doesn’t permit more than 1 (one) START/STOP every 3 minutes from the first.

Standby
Press button for 5 seconds.
Since the compressor and the pump are timed and work together, before stopping they finish the cycle in
progress. A certain interval may therefore be necessary before the unit comes to a total stop. In this condition
the unit is in stand-by and may be restarted by just pressing the button for 5 seconds.
During stand-by preheating of the oil is unnecessary.
Switching off
This operation should always be carried out after having put the unit in stand-by and after all the components have come
to a stop.
Put the door interlock switch to OFF.
If the unit has been at a standstill for more than 4 hours, before restarting the oil must be preheated.

Periodical checks and servicing
WARNING:
The refrigerant R290 (Propane) is
flammable and it must be handled only by
competent and responsible
operators, under the conditions specified
in the safety regulations in force.
Semi-hermetic compressor maintenance
The periodical working pressure and lubricant level check are sufficient
warranty for a long compressor operative life and for the reliability of the
declared performances.
The requested maintenance interventions are:
- lubricant replacement after approx. 100 working hours from the
initial compressor start to remove impurities remained in the
system and collected in the crankcase from refrigerant and
lubricant flow.
- lubricant charge replacement each 10000 working hours to grant
the original viscosity characteristics.
All lubricant replacement operations have to be executed when the compressor is at standstill.
For lubricant replacement are required instruments that are part of the normal equipment of each refrigerator
technician; the necessary instruments to execute the ordinary maintenance operations are:
- vacuum pump
- lubricant hand pump
- flexible hoses with swivel connections and valve opener
- ratchet wrench for square stems
� With working compressor, close the suction valve; when the suction pressure reduces at 0.1÷0.2 bar, switch off
the compressor.
CAUTION: Do not loose any compressor bolt or closing plug
� close the discharge valve
� remove, slowly, discharge valve plug
� remove the oil discharge plug (ref.6, see drawings on catalogue) and let flow all the lubricant in a suitable
package.
Do not pollute the environment with lubricant; it is a special waste and it has therefore to be
carried off as per the regulations in force.

� screw and close well the oil discharge plug and discharge valve plug
� remove the oil charge plug (ref.3, see drawings on catalogue), applying at its place a Schrader service valve
� remove the protection cap from the service valve and connect the lubricant hand pump discharge
� connect the hand pump suction to the lubricant package
� by acting the hand pump, introduce the right oil quantity in the compressor crankcase
� remove the hand pump from the service valve
� connect the vacuum pump suction line to the Schrader service valve
� start the vacuum pump and evacuate the compressor for at least 15 minutes
� disconnect the pump from the service valve and switch off
� screw the protection cap to the service valve
� open the compressor discharge and suction valves
CAUTION
Failure to open the valve before starting, will cause many damages both to compressor
and possibly to operator.
� start the compressor
� after 15 ÷ 20 working minutes, check the lubricant level
The level at which the lubricant settles during
compressor working is highly influenced by the
discharge ratio and therefore by the working
temperatures. Considering that the acceptable
minimum level is 1/4 of oil sight glass, the maximum
level has not to be higher than 3/4 of the sight glass, as
illustrated in figure behind.
Oil Type
Mineral oil SFR68S
Checking the condensing coil
Authorised personnel: maintenance mechanic
Frequency: once a month
Checks:
visually check from outside the unit if there is any dirt, such as paper, dry leaves or simply dust, on the coil. The presence
of such deposits causes a reduction in the air flow with a consequent reduction of efficiency and the possibility that the
high pressure switch could trip resulting in the unit stopping.

Checks:
- check the wiring to ensure that there are no loose wires at connection points and no possibility of doubtful
contacts.
For the check, proceed as follows:
- switch off the unit by putting the switch to ‘0’;
- check that there are no moving parts;
- once the unit has stopped, open the electrical panel;
- gently tug the wires of the contacts to check that the wiring up is secure;
if necessary tighten the screws using a screwdriver.
Seasonal stop
Authorised personnel: maintenance mechanic and electrician.
Frequency: once a year.
Procedure:
- close the water circuit water supply valve;
- if the system risks being exposed to freezing temperatures during the period of inactivity, fully drain the water
circuit;
- disconnect from the electricity supply by means of the power on/off switch, ensuring that the switch cannot be
put to “on” again during the period of inactivity of the system. Seasonal start
Authorised personnel: maintenance mechanic and electrician.
