INSTALLATION

PROCEDURE

1. INSPECT COMPRESSOR OIL

(a) Remove the suction seal cap.

(b) Using a screwdriver with its tip wrapped in protective tape, insert the screwdriver through the suction port and set the VST valve (valve inside suction port) to the open position. NOTICE: Be sure not to damage the piping contact surfaces with the tip of the screwdriver.

*a VST Valve (Valve Inside Suction Port) *b Protective Tape

(c) Lightly shake the compressor with pulley assembly with the suction port facing down, and drain the oil (*1). NOTICE: Do not allow the pulley to come into contact with the compressor oil.

*a Suction Port

(d) With the pulley facing down, rotate the pulley in the direction shown by the arrow 10 times at a rate of approximately once every 2 seconds (*2). NOTICE: If the pulley is rotated, refrigerant or oil might splash out. Thus, keep your face away from the compressor port.

*a Down *b Pulley

(e) Rotate the pulley once in the direction shown by the arrow while quickly turning the compressor so the pulley is up (*3).

*a Up *b Pulley

(f) Proceed with the above procedure (*1) and drain the oil (*4).

(g) Drain the oil by repeating the procedures above approximately 5 times (from (*2) to (*4)).

Standard (Amount of Oil to be Removed):

HINT:

If too much oil has been removed, set the VST valve to the open position through the suction port, and add oil.

2. INSTALL COMPRESSOR WITH PULLEY ASSEMBLY

(a) Temporarily install the compressor with pulley assembly with the 4 bolts.
