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.
6. If any abnormal acoustic noise from air conditioner happened, please turn off the product
and contact with customer services.
7. The refrigerant is environmental friendly product of R134a. Little refrigerant leakage (< 5
g/ year) is allowed for application. If refrigerant leakage seriously, please turn off the
power and wait for at least 2 hours to make sure the refrigerant fully exhaust. Please
also contact the services to replace spare parts.
8. The compressor electrical protecting cover is sealed with silicon for IP54 requirement.
Please do not dismantle the sealed cover or will lose the quality assurance of the
compressor.
1-6. Thermal and Airflow
Internal and external air flow circulation is shown in below diagram. Counter flow design
prevents mixing of internal and external air flows, but waste heat can still be dissipated
from cabinet to the ambient outside air. An internal temperature sensor has been placed
in the return air stream to provide reliable temperature measurement, and for safe
operation.
The heated air inside the cabinet will be cooled by the evaporator. Waste heat absorbed
by the refrigerant will be dissipated through the condenser at the external side.
