Unit Start-Up Procedures
RLC-SVX09H-EN 173
Stopped to Starting:
The stopped to starting diagram shows the timing from a
stopped mode to energizing the compressor.The shortest
allowable time would be under the following conditions:
1. No motor restart inhibit
2. Evaporator and Condenser Water flowing
3. Power up Start DelayTimer has expired
4. Adjustable Stop to Start Timer has expired
5. Need to cool
The above conditions would allow the compressor to start
in 60 seconds.
NOTICE:
Compressor Damage!
If both suction and discharge pressures are low but sub-
cooling is normal, a problem other than refrigerant
shortage exists. Do not add refrigerant, as this may
result in overcharging the circuit.
Use only refrigerants specified on the unit nameplate
(HFC 134a) and Trane OIL00048. Failure to do so may
cause compressor damage and improper unit
operation.
NOTICE:
Equipment Damage!
Ensure that the oil separator and compressor heaters
have been operating for a minimum of 24 hours before
starting. Failure to do so may result in equipment
damage.
