REMOVAL SERVICE POINT
.
<<A>> HOSE/PIPE DISCONNECTION
As the compressor oil and receiver are highly moisture
absorbent, use a non-porous material to plug the hose and
nipples.
To prevent the entry of other foreign bodies, plug the con-
denser, compressor, and expansion valve nipples.
.
<<B>> SUCTION PIPE AND SUCTION FLEXIBLE
HOSE DISCONNECTION
As the compressor oil and receiver are highly moisture
absorbent, use a non-porous material to plug the hose and
nipples.
To disconnect the suction hose from the suction flexible hose,
loosen the union nut on the suction pipe counterclockwise until
nut is completely disengaged from suction hose thread .
Plug the hose nipple to prevent entry of dust and dirt.
INSTALLATION SERVICE POINT
.
>>A<< SUCTION HOSE INSTALLATION
1. When replacing the suction hose, refill them with a specified
amount of compressor oil, and then install them.
2. Ensure o-ring is installed correctly and lubricated then fit
suction hose into suction pipe fitting. With suitable tools hold
the suction hose fitting while tightening union nut to
specified torque.

O-RING REPLACEMENT
1.Removal- use a wooden toothpick or plastic awl to remove
o-ring without damaging the tube.
2.Installation- lubricate o-ring with ND-Oil 8, roll the
new o-ring into captured position.
.
PIPE JOINT PRECAUTIONS
1. Before making any hose and tube connections, always
apply ND-Oil 8 compressor oil to o-ring.
Avoid applying oil in areas with acrylic resin or ABS plastic
as it causes enviromental stress cracking to these resins.
2. Ensure the connecting parts are free of foreign material.

3. Ensure a complete mating of joint before tightening the bolts
or nut.
4. Tighten the joint to the specific torque. For the nut joint, pay
special attention to following cautions.
Always use two wrenches to prevent the tubes from twist-
ing.
Pipes will rotate 15 - 20 clockwise during tightening, so
ensure final position is the correct location.
When finally tightening the pipes, do not rotate the fixed
side(female side).
