Maximum cooling 32/	23 43/26
Maximum heating 27/-	24/18

NOTICE:

- The operating temperature range (outdoor temperature) for cooling only unit is -15^ 43^ ; for heat pump unit is -15^ 43^ .

To ensure safety, please be mindful of the following precautions.

⚠ Warning

• When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the specified refrigerant.
  Any presence of air or other foreign substance in the refrigerant circuit will cause system pressure rise or compressor rupture, resulting in injury.

- When installing or moving this unit, do not charge the refrigerant which is not comply with that on the nameplate or unqualified refrigerant.

Otherwise, it may cause abnormal operation, wrong action, mechanical malfunction or even series safety accident.

- When refrigerant needs to be recovered during relocating or repairing the unit, be sure that the unit is running in cooling mode. Then, fully close the valve at high pressure side (liquid valve). About 30-40 seconds later, fully close the valve at low pressure side (gas valve), immediately stop the unit and disconnect power. Please note that the time for refrigerant recovery should not exceed 1 minute.

If refrigerant recovery takes too much time, air may be sucked in and cause pressure rise or compressor rupture, resulting in injury.

- During refrigerant recovery, make sure that liquid valve and gas valve are fully closed and power is disconnected before detaching the connection pipe. If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.

- When installing the unit, make sure that connection pipe is securely connected before the compressor starts running.

If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.

- Prohibit installing the unit at the place where there may be leaked corrosive gas or flammable gas.

If there leaked gas around the unit, it may cause explosion and other accidents.

- Do not use extension cords for electrical connections. If the electric wire is not long enough, please contact an authorized local service center and ask for a proper electric wire.

Poor connections may lead to electric shock or fire.

- Use the specified types of wires for electrical connections between the indoor and outdoor units. Firmly clamp the wires so that their terminals receive no external stresses.

Electric wires with insufficient capacity, wrong wire connections and insecure wire terminals may cause electric shock or fire.

indoor power cord

1. Bind them evenly.
2. The liquid pipe and gas pipe should be bound separately at the end.

Note:

• The power cord and control wire can't be crossed or winding.
• The drain hose should be bound at the bottom.

Step nine: hang the indoor unit

1. Put the bound pipes in the wall pipe and then make them pass through the wall hole.
2. Hang the indoor unit on the wall-mounting frame.
3. Stuff the gap between pipes and wall hole with sealing gum.
4. Fix the wall pipe.

Installation of outdoor unit

Step one: fix the support of outdoor unit (select it according to the actual installation situation)

1. Select installation location according to the house structure.
2. Fix the support of outdoor unit on the selected location with expansion screws.

Note:

• Take sufficient protective measures when installing the outdoor unit.
- Make sure the support can withstand at least four times of the unit weight.
- The outdoor unit should be installed at least 3cm above the floor in order to install drain joint. (for the model with heating tube, the installation height should be no less than 20cm.)
- For the unit with cooling capacity of 2300W \~5000W, 6 expansion screws are needed; for the unit with cooling capacity of 6000W \~8000W, 8 expansion screws are needed; for the unit with cooling capacity of 10000W \~16000W, 10 expansion screws are needed.

Installation of outdoor unit

1. Fix the power connection wire and signal control wire with wire clip (only for cooling and heating unit).

Note:

• After tighten the screw, pull the power cord slightly to check if it is firm.
• Never cut the power connection wire to prolong or shorten the distance.

Step six: neaten the pipes

1. The pipes should be placed along the wall, bent reasonably and hidden possibly. Min. semidiameter of bending the pipe is 10cm.
2. If the outdoor unit is higher than the wall hole, you must set a U-shaped curve in the pipe before pipe goes into the room, in order to prevent rain from getting into the room.

wall U-shaped curve drain hose

Note:

- The through-wall height of drain hose shouldn't be higher than the outlet pipe hole of indoor unit.

- The water outlet can't be placed in water in order to drain smoothly.

The water outlet can't be placed in water

- Slant the drain hose slightly downwards. The drain hose can't be curved, raised and fluctuant, etc.

Vacuum pumping

Use vacuum pump

1. Remove the valve caps on the liquid valve and gas valve and the nut of refrigerant charging vent.
2. Connect the charging hose of piezometer to the refrigerant charging vent of gas valve and then connect the other charging hose to the vacuum pump.
3. Open the piezometer completely and operate for 10-15min to check if the pressure of piezometer remains in -0.1MPa.
4. Close the vacuum pump and maintain this status for 1-2min to check if the pressure of piezometer remains

in -0.1MPa. If the pressure decreases, there may be leakage.

1. Remove the piezometer, open the valve core of liquid valve and gas valve completely with inner hexagon spanner.
2. Tighten the screw caps of valves and refrigerant charging vent.
3. Reinstall the handle.
