Oil Filter repositioning
Oil fi lter repositioning procedure
1) Turn off both compressors turning the switches in
the off position
2) Turn the main switch OFF wait until the circulation
pump and open the switch general to remove the
power supply to the unit.
3) Put a plate on the handle of the main switch to
prevent accidental starting.
4) Close the valves of suction, discharge and liquid
injection
5) Connect the recovery unit to recover the refrigerant
compressor and within an adequate and clean
storage container.
6) Evacuate the refrigerant until the pressure inside
has achieved a negative pressure (compared
atmospheric pressure). With this reduces to a
minimum the amount of refrigerant dissolved in the
oil.
7) Remove the oil contained in the compressor by
opening the drain cock located below the engine
8) Remove the oil fi lter cover and remove the fi lter
element inside
9) Replace the O-ring of the lid and the inner sleeve.
Do not lubricate the O-ring with mineral oil to non-
pollute the system.
10) Insert the new fi lter element
11) Replace the lid of the fi lter and tighten the screws.
The screws should be tightened alternately
progressively tightening torque 60Nm.
12) Load the oil from the top cap placed on the oil
separator. Given the high hygroscopicity foreign oil,
the Oil fi lling must be done in the shortest possible
time. Do not leave the ester oil exposed atmosphere
for a time greater than 10 minutes.
13) Close the oil fi ller cap.
14) Connect the vacuum pump and evacuate the
compressor up to a vacuum of 230 Pa.
15) On reaching the vacuum level predicted close the
valve on the vacuum pump.
16) Open the valves, suction and liquid injection system
17) Disconnect the vacuum pump from the compressor.
18) Remove the plate WARNING! located on the switch.
19) Close the main switch to power the unit
20) Start the unit according to the starting procedure
described above.
Refer to cap. 4, par 4.4.

personnel.
Pay attention not to disperse harmful liquid or gases.
Recover as much refrigerant gas as possible from the
unit and any freezing solution in the water circuits.
Decommissioning and disposal
At disposal, heat exchangers, fi nned coils, fans or
motors may be recovered if working.
All non-recoverable materials are to be disposed of
in accordance with current standards and regulatory
