2.2 Prevent moisture from entering into the enclosed unit system . When the moisture
entered into the unit, the refrigerant oil and the organic
compound material presented in the hermetic motor will possibly decompose on the
affecting of water . It will result in the capillary depositing and the reducing
of insulation resistance.
It is necessary to install a dryer to dehumidify the residual moisture mixed
in
the refrigerant in the cycling system . The specially defined device for drying and
filtering of R-290 is advised.
2.3 The weight of foreign particles on the inside surface of the heat
exchanger tubes should be less than 0.05g/m2.
Metallic dust should not be permitted to enter the refrigerating system.
This value means the weight of foreign particles filtered after washing
inside surface of the heat exchanger tubes with R-11.
Prevent the impurities from entering into the enclosed unit system . When the impurities entered into
the enclosed system , it will damage the moving mechanism parts and result in the capillary
depositing.
2.4 Eliminate all system contaminants such as trichlorethylene, alkalies,soap ,acid ,oil & washing fluid used at machining the heat
exchanger tubes.
2.5 Purge parts with drynitrogen ordry air to remove remains in parts
(dust,detergent，etc.) before assembly of system.. Time for purging :over one
second for pipe ;over three seconds for heat exchanger . Purging pressure:
0.9±0.1MPaG.Dew point of dry air: Below-20°C.
