1. Precaution 1.1 Safety Precaution. To prevent injury to the user or other people and property damage, the following instructions must be followed. Incorrect operation due to ignoring instruction will cause harm or damage. Before service unit, be sure to read this service manual at first. 1.2 Warning Installation Do not use a defective or underrated circuit breaker. Use this appliance on a dedicated circuit. There is risk of fire or electric shock.
Do not install the product on a defective installation stand. It may cause injury, accident, or damage to the product. Be sure the installation area does not deteriorate with age. If the base collapses, the air conditioner could fall with it, causing property damage, product failure, and personal injury. Do not let the air conditioner run for a long time when the humidity is very high and a door or a window is left open. Moisture may condense and wet or damage furniture.
There is risk of property damage, failure of product, or electric shock. Do not open the inlet grill of the product during operation. (Do not touch the electrostatic filter, if the unit is so equipped.) There is risk of physical injury, electric shock, or product failure. When the product is soaked (flooded or submerged), contact an Authorized service center. There is risk of fire or electric shock. Be caution that water could not enter the product.
could cause product malfunction or inefficient operation. Operational. Do not expose the skin directly to cool air for long periods of time. (Do not sit in the draft). This could harm to your health. Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigerant system There is risk of damage or loss of property. Do not block the inlet or outlet of air flow. It may cause product failure.

Your model may offer slightly different features. POWER - Press the POWER button to turn the unit on or off. When the unit is on, the power indicator light will be green.When the unit is off, the light will go out. MODE - Push this button to cycle through the modes from COOL-HEAT-FAN-COOL.
- FAN:Fan operation only without heating and cooling. UP/DOWN BUTTONS ( / ) - Push the UP (or DOWN) button to increase (or decrease) the set temperature of the unit in cooling or heating mode.The temperature can be set by increments of 1℃ (1℉).The setting temperature appears in the display. NOTE:Press and hold and buttons together for 3 seconds will alternate the temperature display between ℃ & ℉ scale.

T4 Operate on high speed T01 T02 Operate on low speed When T4﹥T01 and lasts for 1 minute, the fan motor will operates at high speed. When T4﹤T02 and lasts for 1 minute, the fan motor will operates at low speed. When T02≤T4≤T01: A) If fan motor is off originally, it will operate at high speed. B) If fan motor is on originally, it will keep on working at the original speed. 6.4.3.

If T2﹥TE8,it turns into the protection of fan motor off , and quits this protection when T2≤TE9.
Operation conditon for heater or compressor Heater(compressor) off (T1-Ts)℉ 2 -2 Heater(compressor) on 6.5.2.1 The Electric heater operates as below: a. When T1﹤Ts-2℉, the fan motor operates, and 3 seconds later, the heater is on and operates at low speed within 30 seconds. After 30 seconds, it will change to the setting speed. If the DAHT temperature checked is higher than the protection temperature, when the heater operating, the fan motor will be off automatically. b.
7 Installation details 7.1 How to install the unit CAUTION: There are sharp edges that can cause serious cuts. When lifting the air conditioner, it is HEAVY. Use 2 people to lift.
- For existing sleeve, you should measure the wall sleeve dimensions. - Install the new air conditioner according to these installation instructions to achieve the best performance. All wall sleeves used to mount the new air conditioner must be in good structural condition and have a rear grille that securely attaches to the sleeve or the flange of the sleeve to secure the new air conditioner. - To avoid vibration and noise, make sure the unit is installed securely and firmly.
- Rotate the vent control lever to either open or close the vent door.(See Fig.6) NOTE: When vent control lever set at CLOSE, only the air inside the room is circulated and filtered. When set at OPEN, some outdoor air will be drawn into room. This will reduce heating or cooling efficiency. - Lift unit level and slide unit into wall sleeve until firmly against front of wall sleeve and secure with 4 screws and washers (supplied) through the unit flange holes. (See Fig.7 and Fig.8) - Reinstall front panel.
7.2 Care and cleaning FRONT PANEL AND CARE - Turn unit off and disconnect power supply. To clean, use water and a mild detergent. DO NOT use bleach and abrasive. Some commercial cleaners may damage the plastic parts. OUTDOOR COIL - Coil on outdoor side of unit should be checked regularly. Unit will need to be removed to inspect dirt build-up that will occur on the inside of the coil. If clogged with dirt and soot, coil should be professionally cleaned.
Prevent clogged indoor coil. Reduce risk of premature component failure. - To Clean Air Filters: Vacuum off heavy soil. Run water through filter. Dry thoroughly before replacing. - Removing Air Filter (See.Fig.10) - Replacing Air Filter (See.Fig.11) VENT DOOR FILTER IMPORTANT:TURN UNIT OFF BEFORE CLEANING. - Make sure to remove the shipping screw from the vent door.(See.Fig.5) - Rotate the vent control lever to open the vent door. (See. Fig.6) - Remove four screws from the vent door filter. (See.Fig.
