Receiver/Dryer, Replacing Without The Need For Flushing Refrigerant Circuit
In the receiver/dryer usually there is a dryer cartridge or a desiccant bag are installed (depending on the design of the refrigerant circuit). Refer to DRYER BAG/DRYER CARTRIDGE, REMOVING AND INSTALLING (REFRIGERANT CIRCUIT - 1 , REFRIGERANT CIRCUIT - 2 , REFRIGERANT CIRCUIT 1234yf - 2 , REFRIGERANT CIRCUIT GENERAL INFORMATION R134a , REFRIGERANT CIRCUIT R134a ) and MAINTENANCE, DIAGNOSIS - FLUID CAPACITY TABLES / REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS / REFRIGERANT R1234YF CAPACITY / APPROVED REFRIGERANT OILS AND REFRIGERANT OIL CAPACITIES /TECHNICAL DATA (HVAC) .
- Pay attention to the general information for replacing components. Refer to GENERAL INFORMATION FOR REPLACING COMPONENTS .
Cleaning the refrigerant circuit means flushing with refrigerant R1234yf. Refer to REFRIGERANT CIRCUIT, CLEANING .
- For example, no escape of refrigerant and no ingress of moisture and dirt into circuit.
- If it is determined at a gas analysis that contaminated refrigerant was in the circuit but there is no concern about the A/C system function. Refer to REFRIGERANT GAS ANALYSIS, PERFORMING .
-- Discharge the refrigerant circuit. Refer to WORKING WITH A/C SERVICE STATION (REFRIGERANT CIRCUIT, DISCHARGING WITH A/C SERVICE STATION ).
-- Remove The Receiver/Dryer. Refer to RECEIVER/DRYER, REMOVING AND INSTALLING (REFRIGERANT CIRCUIT - 1 , REFRIGERANT CIRCUIT - 2 , REFRIGERANT CIRCUIT 1234yf - 2 , REFRIGERANT CIRCUIT GENERAL INFORMATION R134a , REFRIGERANT CIRCUIT R134a ) .
-- Remove dirt from the receiver/dryer.
-- Weigh the removed receiver/dryer.
-- Add refrigerant oil to the new receiver/dryer until it is the same weight as the receiver/dryer that was removed.
-- Install the new receiver/dryer. Refer to RECEIVER/DRYER, REMOVING AND INSTALLING (REFRIGERANT CIRCUIT - 1 , REFRIGERANT CIRCUIT - 2 , REFRIGERANT CIRCUIT 1234yf - 2 , REFRIGERANT CIRCUIT GENERAL INFORMATION R134a , REFRIGERANT CIRCUIT R134a ) .
-- Assemble, evacuate and charge the refrigerant circuit. Refer to WORKING WITH A/C SERVICE STATION .
