1.7 Filter can be easily accessed for cleaning.

1.8 Leave enough free space to allow access for routine maintenance.

1.9 Install at least 10 ft. (3 m) away from the antenna of TV set or radio. Operation of the air conditioner may interfere with radio or TV reception in areas where reception is weak. An amplifier may be required for the affected device.

1.10 Do not install in a laundry room or by a swimming pool due to the corrosive environment.

Minimum Indoor Clearances

Step2: Install Mounting Plate

2.1 Take the mounting plate from the back of indoor unit.

2.2 Ensure to meet the minimum installation dimension requirements as step 1, according to the size of mounting plate, determine the position and stick the mounting plate close to the wall.

2.3 Adjust the mounting plate to a horizontal state with a spirit level, then mark out the screw hole positions on the wall.

2.4 Put down the mounting plate and drill holes in the marked positions with drill.

2.5 Insert expansion rubber plugs into the holes, then hang the mounting plate and fix it with screws.

Step3: Drill Wall Hole

A hole in the wall should be drilled for refrigerant piping ,the drainage pipe, and connecting cables.

3.1 Determine the location of wall hole base on the position of mounting plate.

3.2 The hole should be have a 70mm diameter at least and a small oblique angle to facilitate drainage.

3.3 Drill the wall hole with 70mm core drill and with small oblique angle lower than the indoor end about 5mm to 10mm.

3.4 Place the wall sleeve and wall sleeve cover(both are optional parts) to protect the connection parts.

Caution: When drill the wall hole, maker sure to avoid wires, plumbing and other sensitive components.

Step4: Connecting Refrigerant Pipe

4.1 According to the wall hole position, select the appropriate piping mode. There are three optional piping modes for indoor units as shown in the figure below: In Piping Mode 1 or Piping Mode 3, a notch should be made by using scissors to cut the plastic sheet of piping outlet and cable outlet on the corresponding side of the indoor unit.

Note: When cutting off the plastic sheet at the outlet, the cut should be trimmed to smooth.
