INDOOR UNIT INSTALLATION
Step1: Select Installation location
1.1 Ensure the installation complies with the installation minimum dimensions (defined below) and meets the minimum and maximum connecting piping length and maximum change in elevation as defined in the System Requirements section.
1.2 Air inlet and outlet will be clear of obstructions, ensuring proper airflow throughout the room. 1.3 Condensate can be easily and safely drained. 1.4 All connections can be easily made to outdoor unit. 1.5 Indoor unit is out of reach of children. 1.6 A mounting wall strong enough to withstand four times the full weight and vibration of the unit. 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. 1.11 For ETL certification area, Caution: Mount with the lowest moving parts at least 8 ft. (2.4 m) above
floor or grade level.

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.

Note: (I) Make sure the mounting plate is firm enough and flat against the wall after installation. (II) This figure shown may be different from the actual object, please take the latter as the standard.

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.

Steps: Connect Drainage Hose

5.1 Adjust the drainage hose(if applicable)

In some model, both sides of the indoor unit are provided with drainage ports, you can choose

one of them to attache the drainage hose. And plug the unused drain port with the rubber

attached in one of the ports.

Drainage ports
5.2 Connect the drainage hose to the drainage port, ensure the joint is firm and the sealing effect is good.
5.3 Wrap the joint firmly with teflon tape to ensure no leaks. Note: Make sure there is no twists or dents, and the pipes should be placed obliquely
downward to avoid blockage, to ensure proper drainage.

Note: (I) Make sure the drainage hose is at the bottom.

(II) Avoid crossing and bending of parts.

7.2 Using the insulating tape wrap the refrigerant pipes, connecting wires and drainage hose together tightly.

Steps: Mount Indoor Unit 8.1 Slowly pass the refrigerant pipes, connecting wires and drainage hose wrapped bundle through
the wall hole. 8.2 Hook the top of indoor unit on the mounting plate. 8.3 Apply slight pressure to the left and right sides of the indoor unit, make sure the indoor unit is
hooked firmly. 8.4 Push down the bottom of indoor unit to let the snaps onto the hooks of the mounting plate, and
make sure it is hooked firmly.
Sometimes, if the refrigerant pips were already embedded in the wall, or if you want to connecting the pips and wires on the wall, do as below: (I) Hook the top of the indoor unit on the mounting plate without piping and wiring. (II) Lift the indoor unit opposite the wall, unfold the bracket on the mounting plate, and use this
bracket to prop up the indoor unit, there will be a big space for operation. (Ill) Do the refrigerant piping, wiring, connect drainage hose, and wrap them as Step 4 to 7.

Inspections Before Test Run

Do the following checks before test run.

Description

Inspection method

· Check whether the power supply voltage complies with specification.

Electrical

· Check whether there is any wrong or missing connection between the

safety inspection power lines, signal line and earth wires.

· Check whether the earth resistance and insulation resistance comply with

requirements.

· Confirm the direction and smoothness of drainage pipe. · Confirm that the joint of refrigerant pipe is installed completely. Installation · Confirm the safety of outdoor unit, mounting plate and indoor unit safety inspection installation. · Confirm that the valves are fully open. · Confirm that there are no foreign objects or tools left inside the unit.
· Complete installation of indoor unit air inlet grille and panel.

· The piping joint, the connector of the two valves of the outdoor unit, the

valve spool, the welding port, etc., where leakage may occur.

· Foam detection method:

Apply soapy water or foam evenly on the parts where leakage may occur,

and observe whether bubbles appear or not, if not, it indicates that the

leakage detection result is safe.

· Leak detector method:

Refrigerant leakage detection

Use a professional leak detector and read the instruction of operation,

detect at the position where leakage may occur.

· The duration of leak detection for each position should last for 3 minutes

or more;

If the test result shows that there is leakage, the nut should be tightened

and tested again until there is no leakage;

After the leak detection is completed, wrap the exposed pip connector of

indoor unit with thermal insulation material and wrap with insulation

tape.
