Oil Preload
The oil in the compressor is PAG (polyglycols) 100 made by FUCHS RENISO PAG 100.
ATTENTION: Do not charge with any oil other than that specified by the manufacturer. For further
information, contact a Hillphoenix service representative.
ATTENTION: The pre-charge must be run immediately prior to draining.
ATTENTION: the pre-charge amount is 3.5 ounces.
The amount of oil may need to be adjusted in light of the refrigerant load. This must be done during the draining
procedure described below.
System Drain
For the refrigerating equipment and the compressors to work properly, it is essential to correctly draw a vacuum
on the system to ensure values of air and especially of humidity below the permissible values.
Charging the new refrigerant requires the use of polyester-based oils with characteristics of high hygroscopicity,
necessitating greater attention when drawing a vacuum.
The duration of the evacuation phase is variable as it depends on several factors, but must be at least 24 hours.
In addition to reaching a vacuum level of at least 0.004 Psi, it must remain constant over time.
The IND1 indicator of liquid passage
must
be green to indicate the absence of humidity.
ATTENTION: Before proceeding with the evacuation phase, check that all the valves on the unit and
on the system are open.
ATTENTION: The evacuation phase can take place when the equipment is not electrically powered.
