Installation Manual
• After the installation work, be sure to check for gas
leaks of the pipe connections with nitrogen.
CAUTION
1. Do not put the crescent wrench on the charge
orifice or cover.
The valve may be broken.
2. If applying excessive torque, the nut may break
according to some installation conditions.
• Pressure of R410A is higher than that of R22
(Approx. 1.6 times).
Therefore, using a torque wrench, tighten the flare
pipe connecting sections that connect the indoor/
outdoor units at the specified tightening torque.
Incomplete connections may cause not only a gas
leak, but also trouble with the refrigeration cycle.
Do not apply refrigerant oil to the flared
surface.
