[. . . ] The power source is the same as the corresponding name plate. Install an exclusive branch circuit of the power. A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it. Selection of pipe To this unit, both liquid and gas pipes shall be insulated as they become low temperature in operation. [. . . ] If wiring is not correct, proper operation can not be carried out and will cause defect. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person. The type of connecting wire is H05RN-F or H07RN-F. If the fuse on PC board is broken please change it with the type of T. The wiring method should be in line with the local wiring standard. After installation, the power plug should be easily reached. A breaker should be incorporated into fixed wiring. The breaker should be all-pole switch and the distance between its two contacts should be not less than 3mm.

Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 2. Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer. Connecting the pipe of gas side first makes working easier. The connection pipe is specialized for R410A. Flare nut Forced fastening without careful centering Half union may damage the threads and cause a leakage of gas.

CAUTION: 1. If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate. 2. Please do not let other cooling medium, except specified one (R410A), or air enter into the cooling circulation system. Otherwise, there will be abnormal high pressure in the system to make it crack and lead to personal injuries. Service port cap Valve rod cap 1. Power Source Installation The power source must be exclusively used for air conditioner. (Over I0A) In the case of installing an air conditioner in a moist place, please install an earth leakage breaker. For installation in other places, use a circuit breaker as far as possible. 2. Cutting and Flaring Work of Piping Pipe cutting is carried out with a pipe cutter and burs must be removed. After inserting the flare nut, flaring work is carried out. A Flare tooling die 1.

Please don't do the drainage as shown below. Less than 5cm It becomes high midway. The gap with the ground is too small There is the bad smell from a ditch Please pour water in the drain pan of the indoor unit, and confirm that drainage is carried out surely to outdoor.
