Cautions
1. In any case the compressor will restart 3 minutes after power failure
2. The air-conditioner adopts three core plugs: Modification will void warranty
3. Working voltage of the air-conditioner must keep within the range of 115VAC±10. If the
voltage is too high or low will lead to damage of the compressor.
4. The normal working environment temperature of the air conditioner is: 0F to115F
Maintenance and Safeguard
It will keep at maximum performance ratings if you perform routine maintenance. After running
for 90 days, you must clean up dust around the fins of the heat exchanger in order to keep
refrigeration performance at optimum
TROUBLE SHOOT CHART
