Caution:
• Read the manual before setting to work!
• Always keep cooling unit in upright position and do not shock
• Power supply 230 50Hz!
• Run cooling unit always with correct coolant level otherwise damage of
pump may occur!
• Only use cooling hoses with sufficient pressure and coolant resistance!
• Never operate damaged or leaking equipment!
• Before starting any service work disconnect the cooling unit from power
supply!
• Never carry out any work at the refrigeration cycle, this work must be car-
ried out at manufacturer site!

1 Description
The cooling unit XRCA-5001-OA is designed to provide a continues flow of cooling
fluid at a constant temperature.
Oil circulates etween the cooling unit and the heat source.
The oil is chilled y an air-cooled refrigeration system (refrigerant R 134A).The
cooling unit has a main switch to start the refrigeration system. The oil level in the
reservoir is supervised y a level switch. If the level drops elow minimum, the
refrigeration cycle stops and the pilot lamp "Oil level low" is activated and the safety
circuit is activated.
The maximum cooling capacity of the cooling unit depends on the am ient and the
fluid temperature. The cooling capacity is 5000W related to 40 °C am ient
temperature and +30 °C ± 2°C fluid temperature
Cooling hoses are connected to the cooling unit via screw connection (M26x1,5). Oil
inlet and outlet are marked with sym ols:
Inlet: O
↓
Outlet: O
↑
The oil outlet temperature is monitored y an electronic temperature controller.
This controller is provided with additional contacts and for temperature maximum
signal.
The signals "temperature maximum" and "oil level low" are com ined in a potential
free safety circuit. The oil pressure of the pump is limited y an adjusta le ypass
valve.
Note: Flow switch, thermal switch and bypass valve are factory adjusted
according to specification.
Use only hell Daial 4 ZX-I to refill the cooling circuit!

4 Setting to work
• The cooling unit must e positioned I in an
upright and free-standing position for
sufficient air circulation
• use locking rake at caster
• remove side cover
• connect hoses with cooling unit
• remove plug of filler, fill the cooling unit
with oil up to top indicator
• esta lish electrical connection
•
Note: Operate equipment only with
correct coolant level, otherwise danger
of pump destruction!
• switch on the equipment for some minutes
for the ventilation of the circuit
• replace transport cap of reservoir y
applied plastic cap
• mount cover

5 Settings
Note:
The temperature controller the flow rate and the bypass valve are adjusted ac-
cording specification. ettings of oil outlet temperature, temperature maximum
(parameter P1) and anti freezing should not be changed. If it is necessary to
change these settings refer to the following:

Oil outlet temperature (rated value) T1
Press SET-key and keep it pressed (rated value is shown on display)
Adjust new value with keys  (UP) or  (DOWN)
Release SET-key (actual value is shown on display)
Note: Hysteresis of T3 is adjusted at ± 4°C symmetrical to rated value
Anti freezing T2
Press keys  (UP) and  (DOWN) simultane-
ously for 4 seconds, P1 is shown on display
Select to parameter P30 with key  (UP)
Press SET-key and keep it pressed

Note: Hysteresis of anti freezing T2 is ad-
justed at 4°C. If temperature drops below an-
ti freezing temperature (+5 °C) refrigerating
unit runs only if temperature exceeds +9 °C.

6 Maintenance
In order to achieve maximum cooling capacity keep the condenser of the cooling unit
clean. Regularly once a week check this heat exchanger and if necessary clean it:
Clean fins of heat exchanger:
Remove dust by forcing it out in the opposite direction from which it entered. If com-
pressed air is available, direct the air against the inside of the condenser.
Check oil level regularly and refill if necessary.
