(2)
Dehydrator bypass valve (figure 19, item 8).
(3)
Purge valve (figure 19, item 9).
(4)
Charge and drain valve (figure 19, item 10).
3.
Align the air conditioning refrigerant piping for the condensing unit to be started by CLOSING the following valves in
AMS 2:
! CAUTION
Do not operate both condensing units at the same time with RFAC-39, LIQUID LINE CRVR CO
.and RFAC-41, SUCT LINE CRSVR COV. OPEN or return problems and damage to the con-
denser could occur.
a.
RFAC-39, LIQUID LINE CRVR CO, liquid line crossover cut out, located in overhead
b.
RFAC-41, SUCT LINE CRSVR COV, suction line crossover cut out, located in overhead
4.

a.
OPEN the compressor suction valve (figure 19, item 7) one full turn.
b.

Open the compressor suction valve slowly to prevent rapid pumping down of suction pressure
Damage to condenser could result from lack of lubrication.
c.
Slowly, OPEN the compressor suction valve (figure 19, item 7) as suction pressure decreases.
d.
Verify that the condenser water temperature gauge remains in the NORMAL range.
e.
Verify that the following gauges read in the normal operating range:
(1)
Liquid line temperature gauge
(2)
Suction pressure gauge
(3)
