Insert nut into union. First tighten nut by hand as much as
possible. Then, tighten nut to specified torque.
(Refer to "Special Parts Fixing Nuts and Bolts" in this section)



LEAK AT REFRIGERANT LINE
CONNECTIONS

1) Check the torque on the refrigerant line fitting and, if too
loose, tighten to the specified torque.
 Use two wrenches to prevent twisting and damage to the
Line.

Do not over tighten.
2) Perform a leak test on the refrigerant line fitting.
3) If the leak is still present, discharge and recover the
refrigerant from the system.
4) Replace the O-rings.

O-rings cannot be reused. Always replace with new
ones.


 Be sure to apply specified compressor oil to the new O-
rings.


5) Retighten the refrigerant line fitting to the specified torque.

Use two wrenches to prevent twisting and damage to the
line.
6) Evacuate, charge and retest the system.

LEAK IN THE HOSE
If the compressor inlet or outlet hose is leaking, the entire hose
must be replaced. Refrigerant hose must not be cut or spliced
for repair.
1) Locate the leak.
2) Discharge and recover the refrigerant.
3) Remove the hose assembly.

Cap the open connections at once.
4) Connect the new hose assembly.

Use two wrenches to prevent twisting or damage to the
hose fitting.



Tighten the hose fitting to the specified torque.
5) Evacuate, charge and test the system.

COMPRESSOR LEAKS
If leaks are located around the compressor shaft seal or shell,
replace or repair the compressor.
