Liquid Line Filter Drier

Filter driers are specifically designed for R-22 or Puronr refrigerant. Only operate with the appropriate drier using factory authorized components.

It is recommended that the liquid line drier be installed at the indoor unit. Placing the drier near the TXV allows additional protection to the TXV as the liquid line drier also acts as a strainer.

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

To avoid performance loss and compressor failure, installation of filter drier in liquid line is required.

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

To avoid filter drier damage while brazing, filter drier must be wrapped in a heat-sinking material such as a wet cloth.

Refer to Fig. 22 and install filter drier as follows:

1.Braze 5-in. liquid tube to the indoor coil.

2.Wrap filter drier with damp cloth.

3.Braze filter drier to above 5” liquid tube. Flow arrow must point towards indoor coil.

4.Connect and braze liquid refrigerant tube to the filter drier.

Refer to Fig. 23 and install filter drier as follows:

1.Braze 5 in. liquid tube to the indoor coil.

2.Wrap filter drier with damp cloth.

3.Braze filter drier to 5 in. long liquid tube from step 1.

4.Connect and braze liquid refrigerant tube to the filter drier.

Suction Line Filter Drier

The suction line drier is specifically designed to operate with Puronr, use only factory authorized components. Suction line filter drier is used in cases where acid might occur, such as burnout. Heat pump units must have the drier installed between the compressor and accumulator only. Remove after 10 hours of operation. Never leave suction line filter drier in a system longer than 72 hours (actual time).
