Warning

GENERAL INFORMATION

The air conditioner is the first class electric appliance. It must be properly grounding with specialized grounding device by a professional. Please make sure it is always grounded effectively, otherwise it may cause electric shock. The yellow-green wire in air conditioner is grounding wire, which can't be used for other purposes. The grounding resistance should comply with national electric safety regulations. The appliance must be positioned so that the plug is accessible.
All wires of indoor unit and outdoor unit should be connected by a professional. If the length of power connection wire is insufficient please contact the supplier for a new one. Avoid extending the wire by yourself.
For the air conditioner with plug,the plug should be reachable after finishing installation. For the air conditioner without plug, an circuit break must be installed in the line.
If you need to relocate the air conditioner to another place, only the qualified person can perform the work. Otherwise, it may cause personal injury or damage. Select a location which is out of reach for children and far away from animals or plants.If it is unavoidable, please add the fence for safety purpose.
The indoor unit should be installed close to the wall.

INSTALLING THE OUTDOOR UNIT
Location
Use bolts to secure the unit to a flat, solid floor. 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 pipes
Use suitable connecting pipes and equipment for the refrigerant R32.

INSTALLER
Install the drain fitting and the drain hose (for model with heat pump only)
Condensation is produced and flows from the outdoor 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.

The sum of the capacity codes of the indoor units should be among 50%-150% of that of the outdoor unit.
The refrigerant pipes must not exceed the maximum heights 5m(14K&18K)or 10m(21K&24Kx3&28K).

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.
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 3way 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.

SAFETY OPERATION OF FLAMMABLE REFRIGERANT

INSTALLER

Qualification requirement for installation and maintenance man
All the work men who are engaging in the refrigeration system should bear the valid certification awarded by the authoritative organization and the qualification for dealing with the refrigeration system recognized by this industry. If it needs other technician to maintain and repair the appliance, they should be supervised by the person who bears the qualification for using the flammable refrigerant. It can only be repaired by the method suggested by the equipment's manufacturer.

Installation notes
The air conditioner is not allowed to use in a room that has running fire (such as fire source, working coal gas ware, operating heater). It is not allowed to drill hole or burn the connection pipe. The air conditioner must be installed in a room that is larger than the minimum room area. The minimum room area is shown on the nameplate or following table a. Leak test is a must after installation.
