Startup Procedure
WARNING
Hazardous Service Procedures!
Failure to follow all precautions in this manual and on
the tags, stickers, and labels could result in death or
serious injury.
Technicians, in order to protect themselves from
potential electrical, mechanical, and chemical
hazards, MUST follow precautions in this manual and
on the tags, stickers, and labels, as well as the
following instructions: Unless specified otherwise,
disconnect all electrical power including remote
disconnect and discharge all energy storing devices
such as capacitors before servicing. Follow proper
lockout/tagout procedures to ensure the power can
not be inadvertently energized. When necessary to
work with live electrical components, have a qualified
licensed electrician or other individual who has been
trained in handling live electrical components perform
these tasks.
NOTICE
Equipment Damage!
Failure to follow instructions could result in
equipment damage.
Improper phasing can result in equipment damage
due to reverse rotation.
1. Confirm phase sequencing "A-B-C".
Note: Unit is equipped with auxiliary phase monitors. If the
Phase Indicator pilot light is on, the phasing is
incorrect. Phase Indicator (red) pilot lights are
located in the door of each shore power/cam
connection panel.
2. Turn chilled water pump switch to "HAND", check for
leaks and repair.
3. With water running, adjust water flow via butterfly valve,
check pressure drop and compare with
and
Figure 36, p. 38
to confirm desired flow rate.
4. If required, add appropriate amount of glycol to system.
RTAC-SVX005A-EN
5. Run pump to thoroughly mix solution.
6. Turn chiller water pump to automatic position.
7. Confirm evaporator heat switch located on shore

Checking Operating Conditions
Once the unit has operated for at least 30 minutes and the
system has stabilized, complete the following to ensure
proper unit operation.

Differential Pressure Check
F0 Style Chillers
1. Close both ball valves on pressure gauge tee.
2.
3. Close left hand valve and open right hand valve, record
4. Subtract largest pressure reading from smallest to
5. Close both ball valves on pressure gauge tee.
F2-F4 Style Chillers
1. Open both ball valves feeding differential pressure
2. Record differential pressure provided on gauge.
3. Close both ball valves feeding differential pressure

Check evaporator water flow and pressure drop
following procedure listed below. These readings
should be stable at proper levels. Refer to
38
and
Figure 36, p. 38
for pressure drop vs. flow
charts.
If pressure differential drops off, clean all evaporator
water supply strainers, as well as check on all air vents
in the chilled water loop.
