1. Product Instruction
1-1. General Description
The Heat Exchanger (HEX) is designed for direct air to air heat exchange to remove the heat from
the cabinet, and there is designed for IP55 sealed outdoor telecom cabinet to provide stable and optimum
internal conditions for equipment and avoid hotspot inside the cabinet. It is easy to be installed in the
cabinet with the nuts.
The internal and the external air circulation loops of the HEX are separated to prevent the
introduction of dust, humidity and dirt. The fan on the external air loop conforms to IP55 protection rating.

1-5. Configuration & Maintenance
Make sure the HEX 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.
In order to assure the HEX running at optimal condition, the condenser should
be cleaned once annually at least; user can clean the condenser with flow 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 heat exchangers is used for drainage, please clear
drain holes when the maintenance. Please also notice that following:
1. Check wires are connected correctly, and the insulation is not cracking or
broken.
2. Do not wipe the product with organic solvent, volatile substances like toluene or
gasoline, it will destroy the powder-coated surface.
3. Turn off the power before maintaining.
4. Please turn off power and remove dry contact connector while non-operating for
a long time.
5. If any abnormal acoustic noise from HEX happened, please turn off the product
and contact with customer services.

6. 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.
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.
