3.
Align refrigerant piping system by placing the following valves in the CLOSED position:
! CAUTION
To prevent oil return problems and possible damage to condenser, do not operate both condens-
ing units at the same time with RFSS-13, LIQUID LINE CRSVR CO and RFSS-20, SUCT LINE
CRSVR COV valves open.
a.
RFSS-13, LIQUID LINE CRSVR CO (figure 22, item 1), liquid line crossover cut out
b.
RFSS-20, SUCT LINE CRSVR COV (figure 22, item 2), suction line crossover cut out
4.
Start the standby reefer condenser unit by completing the following actions:
a.
OPEN the compressor suction valve (figure 19, item 7) one full turn.
b.

(1)
Main power disconnect switch (figure 19, item 11)
(2)
Power ON/OFF switch (figure 19, item 12)
! CAUTION
Open the compressor suction valves slowly to prevent rapid pumping down of suction pressure
Damage to the condensers 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 remain in the NORMAL range.
e.
Verify that the following gauges read in the normal operating range:
