3. Never leave the remote control exposed to the rays of the sun.
4. Keep the remote control at a distance of at least 1m from the television or other electrical appliances.

OPERATION INSTRUCTIONS

• Attempt to use the air conditioner under the temperature beyond the specified range may cause the air conditioner protection device to start and the air conditioner may fail to operate. Therefore, try to use the air conditioner in the following temperature conditions.

Fixed air conditioner: 63 °F - 90°F

Inverter air conditioner:

• With the power supply connected, restart the air conditioner after shutdown, or switch it to other mode during operation, and the air conditioner protection device will start. The compressor will resume operation after 3 minutes.

Characteristics of heating operation (applicable to Heating pump)

• Preheating: When the heating function is enabled, the indoor unit will take 2~5 minutes for preheating, after that the air conditioner will start heating and blows warm air.
• Defrosting: During heating, when the outdoor unit frosted, the air conditioner will enable the automatic defrosting function to improve the heating effect. During defrosting, the indoor and outdoor fans stop running. The air conditioner will resume heating automatically after defrosting finish.

Emergency button: Open the panel and find the emergency button on the electronic control box when the remote controller fails . (Always press the emergency button with insulation material.)

INSTALLATION MANUAL---Information for the installer

Step1: Select Installation location

• 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.
• Air inlet and outlet will be clear of obstructions, ensuring proper airflow throughout the room.
• Condensate can be easily and safely drained.
• All connections can be easily made to outdoor unit.
• Indoor unit is out of reach of children.
• A mounting wall strong enough to withstand four times the full weight and vibration of the unit.
• Filter can be easily accessed for cleaning.
• Leave enough free space to allow access for routine maintenance.
• 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.
• Do not install in a laundry room or by a swimming pool due to the corrosive environment

Step2: Install Mounting Plate

1. Take the mounting plate from the back of indoor unit.
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.
3. Adjust the mounting plate to a horizontal state with a spirit level, then mark out the screw hole positions on the wall.
4. Put down the mounting plate and drill holes in the marked positions with drill.
5. Insert expansion rubber plugs into the holes, then hang the mounting plate and fix it with screws.

Note:

• Make sure the mounting plate is firm enough and flat against the wall after installation.
• 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.

1. Determine the location of wall hole base on the position of mounting plate.
2. The hole should be have a 70mm diameter at least and a small oblique angle to facilitate drainage.
3. Drill the wall hole with 70mm core drill and with small oblique angle lower than the indoor end about 5mm to 10mm.
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.

4.2 Bending the connecting pipes with the port facing up as shown in the figure.

4.3 Take off the plastic cover in the pipe ports and take off the protective cover on the end of piping connectors.

4.4 Check whether there is any sundry on the port of the connecting pipe and make ensure the port is clean.

4.5 After align the center, rotate the nut of the connecting pipe to tighten the nut as tightly as possible by hand.

4.6 Use a torque wrench to tighten it according to the torque values in the torque requirements table; (Refer to the torque requirements table on section INSTALLATION PRECAUTIONS)

4.7 Wrap the joint with the insulation pipe.

Step5: 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.

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.

Step6: Connect Wiring

1. Choose the right cables size determined by the maximum operating current on the nameplate. (Check the cables size refer to section INSTALLATION PRECAUTIONS)
2. Open the front panel of indoor unit.
3. Use a screwdriver, open the electric control box cover, to reveal the terminal block.
4. Unscrew the cable clamp.
5. Insert one end of the cable into the position of control box from the back of the right end of the indoor unit.
6. Connect the wires to corresponding terminal according to the wiring diagram on the electric control box cover. And make sure that they are well connected.
7. Screw the cable clamp to fasten the cables.
8. Reinstall the electric control box cover and front panel.

Step7: Wrap Piping and Cable

After the refrigerant pipes, connecting wires and drainage hose are all installed, in order to save space, protect and insulate them, it must be bundle with insulating tape before passing them through the wall hole.

7.1 Arrange the pipes ,cables and drainage hose well as the following picture.

Note:

• Make sure the drainage hose is at the bottom.
• A void crossing and bending of parts.

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

Step8: Mount Indoor Unit

1. Slowly pass the refrigerant pipes, connecting wires and drainage hose wrapped bundle through the wall hole.
2. Hook the top of indoor unit on the mounting plate.
3. Apply slight pressure to the left and right sides of the indoor unit, make sure the indoor unit is hooked firmly.
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:

1. Hook the top of the indoor unit on the mounting plate without piping and wiring.
2. 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.
3. Do the refrigerant piping, wiring, connect drainage hose, and wrap them as Step 4 to 7.
