Totaline p504-h164s Liquid Line Filter Drier 16 Ci

Product Description

The TOTALINE p504-h164s is a bi-directional liquid line filter drier rated at 16 cubic inches with 1/2 inch ODF copper-to-copper connections. Designed for use in refrigerant circuits, this filter drier removes moisture, acid, and particulate contamination from the liquid line to protect compressors, metering devices, and other system components. The bi-directional (Bi-Flo) design allows refrigerant flow in either direction, making it well suited for heat pump systems where flow reverses during defrost cycles. Compatible with R-407C refrigerant, it is installed by licensed HVAC-R technicians during system commissioning, maintenance, or after a compressor burnout cleanup procedure.

The p504-h164s is intended for residential and light commercial refrigerant systems operating on R-407C. Its liquid line placement and 16 cubic inch desiccant capacity make it appropriate for split systems and heat pump applications where bi-directional flow protection is required. The copper sweat connection type suits standard field-installed copper linesets. No specific model family compatibility data was provided in the product information.

Compatibility

Designed as an OEM-style replacement liquid line filter drier for residential and light commercial heat pump and air conditioning systems using R-407C refrigerant with 1/2 inch ODF liquid line connections.

Installation Notes

Installation should be performed by a certified HVAC-R technician in accordance with local mechanical codes and EPA Section 608 refrigerant handling regulations. Recover all system refrigerant and isolate the circuit before cutting into the liquid line. The drier should be brazed in place using nitrogen purge to prevent internal oxidation, then the system should be evacuated to the required micron level before recharging. Arrow markings or Bi-Flo labeling indicate acceptable flow directions — verify orientation before final braze.
