FIG. 27 - CHARGING OIL RESERVOIR WITH OIL
CHARGING THE UNIT WITH OIL
the pump discharge connection to the oil charging
valve (A) located on the remote oil reservoir cover
plate. (See Fig. 27) Do not tighten the connection at
the charging valve until after the air is forced out by
pumping a few strokes of the oil pump. This fills the
lines with oil and prevents air from being pumped
into the system.
3. Open the oil charging valve and pump oil into the
system until oil level in the compressor oil reservoir
is about midway in the upper sight glass. Then, close
the charging valve and disconnect the hand oil pump.
4. As soon as oil charging is complete, close the power
supply to the starter or Variable Speed Drive to en-
ergize the oil heater. (See “System Operating Pro-
cedures”, page 28). This will keep the concentration
of refrigerant in the oil to a minimum.
When the oil reservoir is initially charged with oil, the oil
pump should manually be started to fill the lines, pas-
sages, oil cooler and oil filter. This will lower the oil level
in the reservoir. It will then be necessary to add oil to
bring the level back to the center of the upper sight glass.
THE OIL CHARGE
The nominal oil charge for the compressor is: 10 gal.
“B” and “C” compressor; 15 gal. “E” and “F’ compres-
sor.
New oil YORK Refrigeration Type “C” must be used in
the centrifugal compressor. Since oil absorbs moisture
when exposed to the atmosphere it should be kept tightly
capped until used.
OIL CHARGING PROCEDURE
The oil should be charged into the oil reservoir using
the YORK Oil Charging Pump - YORK Part No. 070-
10654. To charge oil into the oil reservoir proceed as
follows:
1. The unit should be shut down.
NOTE: If charging oil to restore the correct level,
the unit may be kept in operation.
2. Immerse the suction connection of the oil charging
pump in a clean container of new oil and connect
