INSTALLING THE OUTDOOR UNIT

Location

• Use bolts to secure the unit to a flat, solid surface. When mounting the unit on a wall or the roof, make sure the support is firmly secured so that it cannot move in the event of intense vibrations or a strong wind.
• Do not install the outdoor unit in pits or air vents.

Installing the refrigerant lines

• Use suitable refrigerant lines and equipment for refrigerant R410A.

• The refrigerant lines must not exceed the maximum heights 33ft(18Kx2 &24Kx2 &24Kx3 &36×2 &36×3 &36×4& 42×2 &42×3 &42×4 &42×5).
• Wrap all the refrigerant pipes and joints.
• Tighten the connections using two wrenches working in opposite directions.

Caution:

• Installation Must be Performed in Accordance with the NEC/CEC by Authorized Personnel Only.
• Install the drain fitting and the drain hose (for model with heat pump only)
• Condensation is produced and flows from the out-door unit when the appliance is operating in the heating mode. In order not to disturb neighbours and to respect the environment,install a drain fitting and a drain hose to channel the condensate water. Install the drain fitting and rubber washer on the outdoor unit chassis and connect a drain hose to it as shown in the figure.

BLEEDING

Humid air left inside the refrigerant circuit can cause compressor malfunction. After having connected the indoor and outdoor units, bleed the air and humidity from the refrigerant circuit using a vacuum pump.

1. Unscrew and remove the caps from the 2-way and 3-way valves.
2. Unscrew and remove the cap from the service valve.
3. Connect the vacuum pump hose to the service valve.
4. Operate the vacuum pump for 10-15 minutes until an absolute vacuum of 10 mm Hg has been reached.
5. With the vacuum pump still in operation, close the low-pressure knob on the vacuum pump coupling. Stop the vacuum pump.
6. Open the 2-way valve by 1/4 turn and then close it after 10 seconds. Check all the joints for leaks using liquid soap or an electronic leak device.
7. Turn the body of the 2-way and 3-way valves. Disconnect the vacuum pump hose.
8. Replace and tighten all the caps on the valves.

CHECK AFTER INSTALLATION

Has the gas leakage been checked?

| May cause unsatisfactory cooling (heating) problems
Is the thermal insulation of the unit sufficient?| May cause condensation and water formation
Is the drainage sufficient?| May cause condensation and water formation
Does the power supply voltage match the rated voltage specified on the nameplate?| The unit may break down or the components may burn out
Are the refrigerant lines and wiring correctly installed?| The unit may break down or the components may burn out
Has the unit been safely grounded?| Risk of electrical shock
Do the line sizes comply with requirements?| The unit may break down or the components may burn out
Are there any obstacles near the air inlet and outlet of the indoor and out- door units?| The unit may break down or the components may burn out or not perform to specifications
Is the refrigerant charge correct  for the length of refrigerant lines installed| Check to see if more refrigerant needs to be added.
