YORK INTERNATIONAL
FIG. 62 – CHARGING OIL RESERVOIR WITH OIL
25721A
OIL CHARGING VALVE
LD00472
➧
➧
valve (A) located on the remote oil reservoir cover
plate. (See Fig. 62) 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 reser-
voir 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. This will keep the concentra-
tion 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,
passages, 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 nominal oil charge for the compressor is: 10 gal. “B”
and “C” compressor; 15 gal. “E” and “F’ compressor.
New oil YORK Refrigeration Type “C” must be used
in the centrifugal compressor. Since oil absorbs mois-
ture 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.
If charging oil to restore the correct
level, the unit may be kept in opera-
tion.
2. Immerse the suction connection of the oil charging
pump in a clean container of new oil and connect
the pump discharge connection to the oil charging
