Packed valve handling precautions
• Open the valve stem until it touches the stopper. Once it is in contact with the stopper, refrain from applying any more force than is
necessary.
• Securely tighten the valve stem cap with torque in the following table:
1.
Remove the valve cover, the electric parts cover and the cord clamp from the outdoor unit.
2.
Connect the connecting cable to the terminal as identified by the matching numbers on the terminal block of indoor and outdoor
unit.
3.
Insert the power cord and the connecting cable fully into the terminal block and secure it tightly with screws.
4.
Use vinyl tape, etc. to insulate the cords which are not going to be used. Locate them so that they do not touch any electrical or
metal parts.
5.
Secure the power cord and the connecting cable with the cord clamp.
6.
Attach the electric parts cover and the valve cover on the outdoor unit.
