Assembly Instructions
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.
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.
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,
tighten by rotating body (4) 1/8" with respect to
adapter (1) or torque to the value shown in the
“Torque Values” table.
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,
tighten by rotating body (8) 1/8" with respect to
adapter (12) or torque to the value shown in the
“Torque Values” table.
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 lock-washer 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
