3.2 Preliminary checks
If the unit is turned off because of a power failure, wait about 10 seconds before restarting it, so that the elec-
tronic part can reset correctly.
The electrical/electronic parts must be collected separately and disposed of in accordance with applicable legisla-
tion.
3.3 USE
Pay particular attention to possible ejection of refrigerant, since:
- contact with the eyes may cause serious injury;
- contact with the skin (given the extremely low boiling temperature) may cause burns.
If refrigerant is ejected into your eyes or onto your skin, rinse with abundant water and immediately seek for
medical assistance.
The unit has been designed for use specifically with R134a refrigerant. The type of refrigerant (R134a) to be
used is specified on the specific label.
After turning on the unit, wait at least five minutes before performing any operation. If the processing cycle is
interrupted for any reason whatsoever (e.g. power failure) the operation must be resumed from scratch.
The external container used for refilling must be homologated for pressures of at least 35 bar and be
equipped with a safety valve (the valve must conform to the regulations for pressurised containers).
The refrigerant storage container must NEVER be filled to over 80% its total capacity to prevent drops in effi-
ciency. Check filling of the oil containers during operation and make sure that they are not overfilled in order to
prevent sudden drops in efficiency. Do not use these containers with different types of substances.
Live parts
MAIN/EMERGENCY SWITCH PLUG
The unit is to be used by one operator only. Any other persons must keep a safety distance both during operation
and during adjustment and maintenance.
Always connect the high and low pressure ducts (red and blue) with the parts provided and do not use them for
purposes different from those specified.
During operation, check the level in the oil tanks to prevent them from overflowing.
Never detach the HP and LP pipes if not specifically indicated in this manual. Do not activate the manual valves
during normal operation if not specifically indicated in the instructions.
