Note: Table values are recommended maximum and minimum evaporator flow rates or maximum and minimum performance limits of the pump. Always keep the
flow rates within the maximum and minimum flow rates of the above table.
Pre-start Checkout
Unit Location and Mounting
1. Inspect the location for installation and verify service
access clearances.
2. Provide adequate blocking to level trailer.
Inspection
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
1. Inspect all wiring connections. Connections should be
clean and tight.
2. Energize crank case and oil separator heaters 24 hours
prior to start up.
Note: Connecting shore power to the unit without main
power energizes the crankcase and oil separator
heaters. DynaView is powered at the same time.
3. Confirm all service and isolation valves are open.

WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
• Check for tight connections for the unit power supply
wiring with the circuit breaker to the terminal block.
• Check interlock wiring, chilled water pump control,
chilled water flow interlock and external auto stop
(required). For further details refer to RTAC-SVX01*EN
or unit wiring schematics.
• If remote alarm contacts, limit warning contact,
emergency stop, external chilled water setpoint or
external current limit setpoint are used, refer to RTAC-
SVX01*EN and the unit wiring for further details.
