ground terminal. Use 2 mm2 (14 AWG) wire and use spring washer to avoid loosening.
10. The heat exchanger should not be accessible to the general public.
11. The installation must contain a device to disconnect all poles of the heat exchanger 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 for use only by qualified personnel.

1-5. Configuration & Maintenance
Make sure the heat exchanger 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 HEX is composed of the key components as the following: Chassis, Heat Exchange
Core, Controller and Fan tray, user can slide out the fan tray easily for replacement of
the controller and fans.

In order to assure the heat exchanger running at optimal condition, the core should be
cleaned once annually at least; user can clean the core 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 core. The bottom hole of the heat exchanger should be clear 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 heat exchanger happened, please turn off the
product and contact with customer services.
1-6. Thermal and Airflow
With the forced convection using the axial fan, the warm air generated by the equipment
will be blowing into the internal return opening and pass though the HEX, then flow out
from internal supply opening, the cold supply air will be used to cool down the system;
while on the opposite side, cooler air from the out environment will be drawn from the
external air inlet side and bring the heat of the HEX out from the external air exhaust
side. The thermal exchange path is shown in the figure below.

7. Fault analysis and processing
Fault State Analysis of the Reasons Solutions
The HEX is running
but the cabinet
temperature is still
high, no obvious
cooling effect.
• The HEX capacity is not
match the load of the
system.
• The ambient
temperature is too high.
• Low efficiency of the
outside.
• Other system failure
• Check the heating load of the
system.
• Ensure the TEC is operating
in correct temperature range.
• Clean the sink.
• Please contact Delta or
authorized Delta service
agent.
8. Installation Notice
Check the surrounding obstacles to make sure the product get enough space for air
circulate.
