Requirements for electric connectionEnglishSafety precaution1. The electric safety regulations must be followed when installing the unit.2. According to the local safety regulations, use qualified power supply circuitand earth leakage circuit breaker.3. Make sure the power supply matches with the requirement of air conditioner.Unstable power supply or incorrect wiring may result in electric shock, fire hazardor malfunction. Please install proper power supply cables before using the airconditioner.4. Properly connect the live wire, neutral wire and grounding wire of power socket.5. Be sure to cut off the power supply before proceeding any work related toelectricity and safety.6. Do not put through the power before finishing installation.7. If the supply cord is damaged, it must be replaced by the manufacturer, its serviceagent or similarly qualified persons in order to avoid hazard.8. The temperature of refrigerant circuit will be high, please keep the interconnectioncable away from the copper tube.9. The appliance shall be installed in accordance with national wiring regulations.Grounding requirement1. The air conditioner is the first class electric appliance. It must be properlygrounded with specialized grounding device by a professional. Please make sureit is always grounded effectively, otherwise it may cause electric shock.2. The yellow-green wire in air conditioner is grounding wire, which can't be used forother purposes.3. The grounding resistance should comply with national electric safety regulations.4. The appliance must be positioned so that the plug is accessible.5. An all-pole disconnection switch having a contact separation of at least 3mm inall poles should be connected in fixed wiring.6. Be sure to install an earth leakage breaker capable of handling maximum ratedcurrent. (One that can handle higher harmonics.)6

Installation of indoor unitStep one: choosing installation locationRecommend the installation location to the client and then confirm it with the client.Step two: install wall-mounting frameStep three: open piping hole1. Choose the position of piping hole according to the direction of outlet pipe.The position of piping hole should be a little lower than the wall-mounted frame,shown as below.WallSpaceto thewallabove150mmLevel meterMark in the middle of itWallSpaceto thewallabove150mmRightLeftø55mm or ø70mmø55mm or ø70mm(Rear piping hole)(Rear piping hole)2. Open a piping hole with the diameter of Ø55 or Ø70 on the selected outlet pipeposition. In order to drain smoothly, slant the piping hole on the wall slightlydownward to the outdoor side with the gradient of 5-10 .7English1. Hang the wall-mounting frame on the wall; adjust it in horizontal position with thelevel meter and then point out the screws fixing holes on the wall.2. Drill the screw fixing holes on the wall with impact drill (the specification of drillhead should be the same as the plastic expansion particle) and then fill the plasticexpansion particles in the holes.3. Fix the wall-mounting frame on the wall with tapping screws (ST4.2X25TA) andthen check if the frame is firmly installed by pulling the frame. If the plasticexpansion particle is loose, please drill another fixing hole nearby.

When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the specified refrigerant (R410A). The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury.
