Suction or Discharge Manifold

NOTE: Two different O-rings are used on compressor manifolds and they are not interchangeable. One is black and is used with aluminum manifolds. The other O-ring is red and is used with brazed steel manifolds. Either O-ring must be replaced with one of the same color.

Removal

1. Discharge refrigerant from system following recommended procedures. Observe all safety precautions.

2. Remove two bolts attaching manifold to compressor, and remove manifold and O-rings.

3. When replacing discharge manifold, transfer pressure relief valve to new discharge manifold.

Installation

1. Lubricate new O-rings with clean refrigerant oil and position them in O-ring grooves of manifold. Use only the O-ring specified for the type of manifold being used.

2. Apply Pipe Sealant with Teflon® D8AZ-19554-A (ESG-M4G194-A) or equivalent to threads of manifold retaining bolts.

   NOTE: When replacing a compressor, use original manifold bolts from removed compressor to attach manifolds to new compressor. DO NOT USE THE SHIPPING CAP BOLTS.

3. Position manifold with O-rings to compressor. Install two retaining bolts and tighten to 18-23 Nm (14-16 lb-ft).

4. Leak test, evacuate and charge system following recommended procedures. Observe all safety precautions.
