INSTALL UNIT INTOWALL SLEEVE 1. Carefully remove shipping tape from the front panel and vet door. See Fig.5. 2. Remove shipping screw from the vent door, if present. See Fig.6. 3. Remove front panel. See Fig.7. 4. Lift unit level and slide unit into wall sleeve until foam seal rests firmly against front of wall sleeve. 5.
FUNCTION AND CONTROL 1. Temperature Parameter • Indoor setting temperature (Tpeset) • Room temperature (Tamb) 2. System Basic Function In any circumstances, the compressor will delay 3 minutes for protection once it’s stated up. Once the compressor is started up, the compressor won’t stop with the change of the indoor temperature. While once the compressor is stopped, it can be started up only after 3 minutes delayed.

55 ~ 80 ℉ (13 ~ 27 ° C). 4) OFF Mode If the OFF mode is selected, all the display will be closed except the power indicator and all the output are invalid. (Except the low temperature resistant protection) If the UP or Down button is pressed, the unit display will extinguish after it displays the ambient temperature for 15 seconds and the indoor indicator will also go out after illuminated 15 seconds.

Error Codes: When the unit is energized, the STATUS LED illuminates. If there is any malfunction or protection, the STATUS LED will blink with the Error code. When the unit is in the OFF status, there is not an error code showing (except the low temperature resistant protection), and the protections - 6, 7, 8 in the following table will be illuminated.

f) LOW TEMPERATURE RESISTANT PROTECTION (valid in wall thermostat mode) ON – invalid. OFF – valid. The default setting is OFF. 3) Configuration – Do not need hotel maintenance personnel to control (configuration is valid after B dial- up is energized, and the configuration is invalid after A dial-up is energized). a) Heat pump and Heat Cool units for selection.

compressor will stop running, outdoor fan will keep running continuously, and the indoor fan is running normally according to the wall thermostat signal. Quit condition: If the outdoor tube temperature ≤ 131 ℉(55 ° C) is over 2 minutes, this protection will be ended.
TROUBLESHOOTING Switch is at the OFF position; or socket and plug is loosened; or the power cord has malfunction; or power No power supply failed. Fuse is burned out Replace the fuse Inspect the power voltage. If it is lower 10% of the rated Supply voltage is too low voltage, please look for the reason, improve the power supply condition and add the regulated power supply.

Check leakage, evacuate with vacuum-pump after Refrigerant is insufficient or leaking repairing leakage, and then charge refrigerant according the spec. Check if the system is blocked by observing the condensation of the evaporator and the pressure value Refrigeration system is blocked of the high pressure manometer, and then take measures to deal with the system.

Refrigerant is insufficient or superabundance Adjust the quantity of the refrigerant Capillary is blocked and the suction temperature Replace capillary is rising. Protection is activated due to overheating The compressor can run smoothly or is blocked. Replace the compressor The air discharge valve is damaged. Check the contact point of the compressor with a multimeter to find out if it is conducted.
DISASSEMBLY PROCEDURE Warning Be sure to wait 10 minutes or more after turning off all power supplies before disassembling work. Note: The procedure below is for heat pump unit with electric heating. There is some difference between it and cooling only unit with electric heating. The difference is pointed out in the diagram; please refer to the related diagram direction.
