Installation Steps

Test the appliance by plugging the power supply cord in a correct outlet of power source
before installation.

A clearance of 20 mm is advisable between the appliance cabinet and the wall. Fix the indoor air intake
panel with the cabinet by employing two screws which packed in the packing bag as shown in Fig.5.

Put the buffers on the installation bracket as shown in Fig.6. Adjust the appliance as shown in Fig.4.
The leveling pads are employed to tilt the appliance in order that the indoor side is about (15 20) mm
higher than the outdoor side for fear the condensate overflow into the room.

The seal foam pads are employed to prevent outside air from leaking into the room (Fig.7) and the
decorating strip is presented for aesthetical appearance as Fig.8.

Condensate will form during the cooling or dry operation, user can choose drainage
or no drainage. Remove the drainage tip and fix the drainage hose when drainage is chosen.
On the contrary, the condensate is splashed to cool the condenser so that the cooling capacity
and energy conservation is improved with a little high noise when no drainage is chosen.

1.Accessories

Fuse and Grounding

A proper time-delay fuse should be employed in the power supply circuit.
For your personal safety, this air conditioner must be grounded.
The extension of power supply cord is inadvisable.
Connect this air conditioner to its own individual wall receptacle to prevent itself and other appliances
