Note: These parts must be sourced locally.
6. Inline connectors
With removal of the output inductor, the power
conductors will be need to be spliced together. Polaris
Electrical Connectors are recommended (Catalog No.: IT-
250). Six (6) pieces are needed. There are two conductors
per phase.

Insulated in-line connectors
7. Piping and fitting changes may be required. Source
locally.
8. Insulation
All units require field installed insulation. Install insulation
before adding refrigerant for proper adhesion.
Heater Information
There are two heaters per compressor:
1. One cartridge/rod style that is the same part number
for both R and S frame compressors. This part number
changed between GP4 classic and VVi. Heaters need to
be ordered as separate service parts for the retrofit to
work. See
for the correct part numbers to
order.
2. The band style has not change between GP4 Classic
and VVi. The existing band style heaters on the RTAE
compressor can be reused.
Compressor Heaters
The compressor must be heated any time it is not running
to prevent refrigerant from condensing in the compressor.
The heaters are sized to maintain a minimum of 18°F or
20°F rise above the ambient temperature.
Two heaters are required: a cartridge type in the suction
end of the rotor housing and a band type on the muffler.
See
for heater details.
