Receiver Tank Replacement

Parent topic: Refrigeration Maintenance

Removal

  1. Recover the refrigerant charge from the unit (see “Refrigerant Recovery” in this chapter).

  2. Unsolder the outlet valve on the liquid outlet line.

  3. Unsolder the liquid line inlet connection.

  4. Loosen the mounting nuts and remove the tank.

  5. Remove the outlet valve from the receiver tank.

Installation

  1. Install a new tank in the unit and tighten the mounting bolts.

  2. Solder the inlet line and outlet valve line with high temperature silver solder (30% silver).

    Note It is strongly recommended that dry nitrogen be used to purge the system during any solder operations (see “Using Pressurized Nitrogen” in this chapter).
    Note If pressurizing with nitrogen, front seat the discharge valve to prevent nitrogen from entering the refrigerant charge.
    3. Caution
    • Equipment Damage
    • Any time the discharge valve is front seated, disconnect the unit power source to prevent accidental compressor start-up.

  4. Pressurize the refrigeration system and check for leaks (see “Refrigerant Leak Test Procedure” in this chapter).

  5. Evacuate the system (see “Evacuation and Cleanup of the Refrigeration System” in this chapter).

  6. Recharge the unit (see “Refrigerant Charge” in this chapter).
