CONDENSER WATER PUMP CONTACT /
RUN STATUS OPTION
This option provides a dry contact which can be used
to turn on the condenser water pump, other device, or
indicate run status. The contact closes whenever one of
the compressors start.
Connections to this contact can be made on Terminals
21 and 22 of TB1 in the power panel. The location of
these terminals is shown in Fig. 30.
This option utilizes a second Relay Output Board and
associated wiring. The part number for the Field Mounted
Pump Control Kit is 471-01232-101. This kit is not re-
quired if a second Relay Output Board is already installed.
NOTE: Any inductive devices (contactor/relay coil) con-
nected to these contacts must be suppressed
with YORK P/N 031-00808-000 supplied by
others. Otherwise, nuisance faults may occur.
OPTIONS
for closer examination by factory service person-
nel is indicated.
H. If the oil is clean and free of metal particles, refill the
compressor with YORK C oil. To add oil or to fill the
compressor crankcase, connect the delivery tube of
the YORK Hand Oil Pump. YORK Part No. 470-10654
or equal to the compressor oil charging and drain
valve. Expel all air from the delivery tube by pumping
it full of oil, allowing a few drips to drip out before
tightening the flare nut to the oil charging valve. Then
open the oil charging valve and pump oil into the crank-
case to the proper level. It is necessary that the suc-
tion end of the hand oil pump be kept submerged
under the oil level in the container at all times, to
avoid entrance of air into the compressor.
I. Before opening the suction or discharge stop valves,
connect a vacuum pump to the pumpout port in the
discharge stop valve. (Pumpout port is port on valve
stem side of valve). With the vacuum line shutoff
valve open, run the vacuum pump until a vacuum of
at least 1000 microns is reached. Stop the vacuum
pump, close the shut-off valve and open the dis-
charge valve fully before disconnecting the line from
the vacuum pump. Disconnect the vacuum pump
and replace the plug in the pumpout port.
NOTE: If suction or discharge valves are not seated
properly, a 1000 micron vacuum can not be ob-
tained. Do not evacuate for long periods of time.
J. Be sure both discharge and suction stop valves
are open before operating the unit.
4. Suction and Discharge Valves and Springs The con-
dition of the suction and discharge valves and springs
should be checked by YORK service personnel on a
yearly basis or every 5000 hours, whichever comes
first.
