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.

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 

Table 3, p. 7

 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 

Table 3, p. 7

 for heater details.
