CAUTION
• Do not put the crescent wrench on the cap or cover.
The valve may break.
• If applying excessive torque, the nut may break
according to some installation conditions.
• After the installation work, be sure to check for gas
leaks of the pipe connections with nitrogen.
• 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 refrigerating machine oil to the flared
surface.
