Installation
Compressor Replacement
If either a 1
st
Gen or 2
nd
Gen GP4 Classic Compressor has
failed on an RTAE Chiller, only the Locked VarVi Service
Compressor can be used as a replacement, as the Classic
chassis has been discontinued. Motor information for a
specific compressor can be obtained by checking the
model number on the compressor nameplate. Motor
number (MN) is stored in the 6
th
and 7
th
digit of the
compressor model number.
Example: Compressor model CHHSRB1A1A0 indicates a
B1 motor, which is a 100T Standard Lift 1
st
Gen GP4 Classic
motor. Refer to RTAE Service Guide (RTAE-SVG001*-EN)
for more detailed instructions for compressor
replacement procedure.
Notes:
•
Piping and fitting modifications may be required.
•
All units will require field installed insulation. Install
insulation before adding refrigerant for proper
adhesion.

(a) Covers both 360-439V and 440-528V voltage range's. Voltage specific replacement compressor for 360-439V or 440-528V depends on chiller rated
voltage. Refer to chiller nameplate to identify the rated voltage. 360-439V motors are used on 380V/400V chillers. 440-528V motors are used on
200V/230V/460V/575V chillers.

Additional Parts Required
Note: Must be ordered separately.
Important:
Only the compressor is delivered as
standard. Additional parts will be required
and must be ordered separately.
Follow steps below to identify additional parts required:
1. Record the model number, digit 5 (R or S) from the
RTAE nameplate located on the unit.
2. Record the model number, digit 7 (number or letter)
from the motor nameplate located on the compressor
motor.
3. Determine which circuit needs the replacement
compressor (circuit #1 or #2).
4. Determine which additional parts need to be ordered
from the list below using the above information and
purchase them for the GP4 Classic compressor
replacement.
