2. Installation Environment Check

Before selecting the installation location, ensure the environment meets the following criteria:

• No heat source or steam source nearby.
• No obstructions around the inlet and outlet of both indoor and outdoor units.
• No smoke or oil in the vicinity.
• No flammable, explosive, or corrosive gases present.

3. Indoor Unit Installation

The indoor unit must be installed on a hard, flat, and firm wall to prevent vibration and noise. Ensure adequate clearance:

• To ceiling: > 15cm
• To obstacle (sides): > 20cm
• To floor: 230-260cm

Mounting Plate Installation:

1. Put the mounting plate on the wall and use a level to make it horizontal.
2. Select the position for at least 5 screws on the plate.
3. Punch holes in the wall.
4. Use expansion screw kits to firmly fix the plate to the wall. Do not use nails.

Drill Wall Hole for Piping:

• After determining where the pipe will go through the wall, drill holes.
• When drilling, ensure to avoid wires, plumbing, gas, and other sensitive components.
• The wall hole should be inclined outward by 5-10°, with a diameter of 60-80mm.
• Use an anti-dust bag to avoid dust when drilling.

Connection Cable Installation:

1. Pass the power cable out from the back of the indoor unit and fix it on the terminal board.
2. Fix the cable with a clamp.

Knock-out Panel:

• According to piping direction, remove the knock-out panel with a knife, and remove burrs to prevent the drain pipe from being broken.

Refrigerant Piping Connection:

1. Use both hands to turn the pipe in the desired direction. It is forbidden to operate with one hand, which will make the tube deform and rupture.
2. Aim at the pipe center, tighten the taper nut with fingers, then tighten the taper nut with 2 wrenches.
3. It's better to use a torque wrench to tighten the taper nut. Refer to the provided torque table for specific values based on pipe size.

Drain Hose Installation:

• Connect the drain hose with the water outlet pipe, and fix it firmly with adhesive tape. The length should be more than 5cm to prevent water leakage.

Wrap the Piping:

• Wrap refrigerant piping, wires, and drain pipe with wrapping tape.

Mount Indoor Unit:

• Put the refrigerant piping out of the wall hole.
• Put the indoor unit on the mounting plate.
• Push the lower part of the indoor unit until a 'click' sound is heard to make sure the indoor unit is firmly fixed to the wall.

Pipe Protecting Ring and Putty:

• To protect piping and wires, a pipe protecting ring shall be installed sealed with putty.

4. Outdoor Unit Installation

The outdoor unit must be installed in a firm and flat place to prevent vibration and noise. Ensure adequate clearance:

• To the obstruction (top): > 20cm
• Air in side: > 10cm
• To the obstruction (sides): > 30cm
• Air out side: > 200cm

Install Outdoor Unit Bracket:

• If installing the air conditioner to a higher place, the operator should wear a safety belt and helmet.
• Use a level to ensure the bracket is horizontal and vertical.
• Use at least 6 expansion bolts to make sure brackets are fixed firmly on the wall.

Mount Outdoor Unit:

• Put the outdoor unit onto the brackets.
• Use 4 screws to fix the feet of the outdoor unit.

Connect Refrigerant Piping:

1. Remove the nut from the stop valves.
2. Aim at the pipe center of the stop valve, tighten the taper nut with fingers.
3. Screw 2 caps.
4. Tighten the taper nut with 2 wrenches. It's better to use a torque wrench to tighten the taper nut. Refer to the provided torque table for specific values based on pipe size.

Attention:

When the length of the connecting pipe is changed, extra amount of refrigerant needs to be added or reduced, so that the operation and performance of the air conditioner will not be compromised.

Electrical Wiring:

1. Remove the electrical box cover.
2. Fix cables to the terminal board according to the wiring diagram on the E-parts cover. Must follow the wiring diagram inside the box cover.
3. Use a clamp to fix cables.
4. Put the electrical box cover back.

Vacuumize:

1. Before vacuuming, check all the nuts of the indoor and outdoor unit are tightened.
2. Connect the stop valve, charging hose, manifold valve, and vacuum pump as shown in the diagram.
3. Turn on handle Lo to vacuumize.
4. Vacuum for 15 minutes at least, make sure the value on the pressure gauge is ≤0.1MPa.
5. Keep pressure for 3-5 minutes after vacuumizing, ensure pressure springback ≤0.05MPa.
6. Open 1/4 liquid valve, and remove the charging hose.
7. Open all the liquid valves and gas valves.
8. Screw all the caps and tighten up.

Trial Operation

After installation, perform a trial operation to ensure proper functioning and safety.

• Electrical Safety Check: Use a multimeter to test possible leaking positions of the outdoor unit shell during trial operation. If there is electricity leakage, turn off power immediately to do further examination.
• Water Drain and Leakage Test: Remove one filter from the indoor unit. Pour in 500ml water along the evaporator for about 20 seconds. Check if water drain can normally flow out and if any water leakage is around the indoor unit.

Maintenance

Regular maintenance ensures the efficiency and longevity of your air conditioner.

• The air filter is removable and washable. It should be cleaned monthly to maintain optimal performance and air quality.
• The unit features a 135°F self-cleaning function for internal sanitation.
