(4)Check gas leak (connected points)
<Packed Valve Handling Precautions>
•Open the valve stem all the way out; so not try to open it beyond the stopper.
•Securely tighten the valve stem cap with the wrench or like.
•Valve stem cap tightening torque is as follows; Gas pipes side (ø9.52) : 29.4 N•m (3.0 kgf•m) Liquid pipe side (ø6.35) : 16.2 N•m (1.7 kgf•m)

(2)Connect the connecting cable to the terminals as identified with their respective matched numbers on the terminal block of indoor and outdoor units. (Strip the sheath of connecting cable with following stripping length to and insert into the terminal block.)
(3)When connecting the connecting cable to outdoor unit terminal, make a loop as shown in the installation diagram of indoor and outdoor unit, to prevent water coming in the outdoor unit.
(4)Insulate the unused cords (conductors) with water coming in the outdoor unit. Process them so that they do not touch any electrical or metal parts.
