Compressor POE Oil
The oil level should be watched carefully upon initial start-up
and for sometime thereafter. Compressor oil must be one of
the following: Copeland brand Ultra 22 CC, Copeland brand
Ultra 32 CC, Copeland brand Ultra 32-3MAF, Mobil EAL Artic
22 CC, or Uniqema RL32-3MAF.
This is synthetic polyolester oil with anti-wear additives and is
highly hygroscopic. Care must be taken to minimize exposure
of the oil to air when charging oil into the system. Oil can
be added to the compressor through the oil ll hole on the
compressor. To add oil, pump in the necessary oil.
Sightglass and Moisture Indicator
A clear glass of liquid indicates that there may be an adequate
refrigerant charge in the system to provide proper feed through
the expansion valve. Bubbling refrigerant in the sightglass
indicates that the system is short of refrigerant charge.
Refrigerant gas ashing in the sightglass could also indicate
an excessive pressure drop in the line, possibly due to a
clogged lter-drier or a restriction elsewhere in the system. An
element inside the sightglass indicates what moisture condition
corresponds to a given element color. If the sightglass does
not indicate a dry condition after about 12 hours of operation,
the oil should be tested for acid and the lter-driers changed if
necessary.
