mm2(14 AWG) wire and use spring washer to avoid loosening.
10. The air conditioner shall be not accessible to the general public.
11. The installation must contain a device to disconnect all poles of the air conditioner from the power supply.
The contact distance in all poles must be 3 mm minimum.
12. To reduce the risk of electrical shock. Means for disconnection must be incorporated in the fixed wiring in
accordance with the wiring rules.
13. This appliance is intended to be used by expert or trained users in shops, in light industry and on farms,
or for commercial use by lay persons”.
Caution :
1. Install the air conditioner on a wall/ door strong enough to withstand the weight of the unit.
2. Do not allow a child to mount on the outdoor unit or avoid placing any object on it.
3. Do not block air inlets or exits.
4. Do not install the air conditioner at any place where there is a danger or flammable gas leakage.

1-5. Configuration & Maintenance
Make sure the air conditioner surface sealed with mounting flange to avoid water penetrates into
shelter through mounting interface. It is suggested to use gaskets sticking on the mounting flange and seal
the gap between flange and cabinet with silicone gel during installation. There should be NO any gap
surround gaskets to avoid water penetrates into enclosure.
The air conditioner is composed as the following key components: they are chassis, cover, controller,
heat exchanger, blowers and compressor etc. It is “not” recommended that the user replace the
compressor, evaporator, and the condenser by themselves; it may damage the system and getting injured.
In order to assure the air conditioner running at optimal condition, the condenser should be cleaned
once annually at least; user can clean the condenser with water directly. The external side fan blade can
also be cleaned with normal pressure water if there is dust accumulation. Please do not use strong water
jet to impact the center of fan and the surface of condenser.
The bottom hole of the air conditioner should be connected to a sealed container through a drainpipe,
please clear drain holes when the maintenance. Please also notice that:
1. Check wires are connected correctly, and the insulation is not cracking or broken.
2. Use Self-test to check the unit running correctly or not. And the supplied air of internal side should be as
cooled air.
3. Do not wipe the product with organic solvent, volatile substances like toluene or gasoline, it will destroy
the powder-coated surface.
4. Turn off the power before maintaining.
5. Please turn off power and remove dry contact connector while non-operating for a long time.

Fault Analysis and Processing
Fault State Analysis of the Reasons Solutions
Power on, and the cabinet
temperature is too high
but the air conditioner is
not working
1.Power failure or no power.
2.The target temperature is higher
than inside temperature.
3.System failure.
1.Check the power supply and the electric
circuit.
2.Re-set the target temperature according
to the system requirement.
3.Please contact the service department.
The air conditioner is
running but the cabinet
temperature is still high,
no obvious cooling effect.
1.The air conditioner capacity is
not match the load of the system.
2.The ambient temperature is too
high.
3.Low efficiency of the condenser.
