Assembly Instructions

Step 1

After tubing or hose has been connected to adapters (1) and (12), install adapter

O-rings (2) and (11)* on adapters. Be sure O-rings are not twisted.

Step2

Generously lubricate adapter O-rings (2) and (11) with the system lubricant to prevent them from scuffing and tearing when coupling body is threaded on adapter.

Step 3

Adapter to S2 male coupling half connection.

A. Lubricate poppet face with system lubricant. Insert poppet valve assembly (3) into body (4). Tighten body (4) on adapter (1).

B. After body and adapter make metal-to-metal contact, torque to the value shown in the "Torque Values" table.

Step4

Adapter to S5 female coupling half connection.

A. Lubricate O-ring (9) liberally with system lubricant. Insert valve and sleeve assembly (10) into body (8). Tighten body (8) on adapter (12).

B. After body and adapter make metal-to-metal contact, torque to the value shown in the "Torque Values" table.

Step 5

Coupling connection.

A. Generously lubricate the gasket seal (5) on the 5400-S2 male coupling half with the system lubricant.

B. Thread the union nut (8) onto the S2 male coupling half. Tighten union nut to torque values shown in the "Torque Values"

table.

IMPORTANT - DO NOT rotate the S5 female coupling half body during connection.

C. After the coupling halves are seated, keep the bodies of the S2 male coupling half (4) and that of the S5 female coupling half (8) from rotating and tighten the union nut to the torque values shown in the "Torque Values" table.

IMPORTANT - DO NOT rotate the S2 or S5 coupling half body during connection.

Bulkhead Mounting — S2 Half

Install lock washer (6) on S2 half, insert S2 male coupling half through bulkhead, and tighten jam-nut (7) so that lockwasher teeth are fully compressed.

Note: Lock washer (6) must be between hex of S2 male half and bulkhead.

IMPORTANT - Generous lubrication is required for all gaskets and O-rings. Lubrication should match system oil and be compatible with refrigerant system.

* Specify O.D. Tubing size of adapter required in

16th of an inch.

Example:

-4 coupling with 3/8" O.D. tubing = 6/16 or -6. Part number is then 202208-6-4.
