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 IP55 requirement. Please do not
dismantle the sealed cover or will lose the quality assurance of the compressor.
1-6. Thermal and Airflow
The internal and external air flow circulation is shown as the figure. Through separated mechanism
design, internal and external air flow won’t be mixed since the waste heat can be dissipated from the
cabinet to the ambience. Internal temperature sensor is placed at return air stream to provide reliable
temperature measurement and safety of operation.
The waste heat generated from the internal equipment will be absorbed by the refrigerant through the
evaporator and dissipate to the ambience by the condenser of external side.
