7.4 TABLE OF MAINTENANCE JOBS ON SCROLL COMPRESSOR
IMPORTANT
At each refrigerant substitution also change the oil.
At each refill of refrigerant or intervention on the refrigerant
circuit, verify the oil and motor insulation.
7.5 CHECKING OF THE PRESSURE VESSELS
It is very important to prevent rust formation on the surface of the
machine’s pressure vessels (evaporator, condenser, reclaim exchanger,
liquid receiver) and that there are no warps.
DANGER – FOR YOUR SAFETY
In the presence of any warps, stop the machine and contact an
After-Sales Service authorized by the manufacturer.
Periodically protect the pressure vessels with paints and/or antioxidant
products.
7.6 CHECKING OF THE WATER FLOW AND CLEANING OF THE
EXCHANGERS
The variation in the flow rate in the exchangers can be caused by the
presence of dirt in filters, by pump wear or wrong manoeuvres, as well
as by the presence of fouling inside the exchangers.
In this case, a chemical wash with suitable products must be carried out.
7.7 EXTRAORDINARY MAINTENANCE
In the event that any extraordinary maintenance jobs are necessary,
contact an After-Sales Service authorized by the manufacturer.
IMPORTANT
In case of non-compliance with the above recommendations, the
manufacturer may not be held liable in respect of any safety
requirements of the machine and, during the warranty period, the
related rights will no longer be valid.
