in its mounting or damage to other components.
3. TURN ELECTRICAL POWER OFF AT THE breaker or fuse box BEFORE installing or
working on the equipment. LINE VOLTAGES ARE HAZARDOUS or LETHAL.
4. OBSERVE and COMPLY with ALL applicable PLUMBING, ELECTRICAL, and
BUILDING CODES and ordinances.
5. SERVICE may be performed ONLY by QUALIFIED and EXPERIENCED PERSONS.
* Wear safety goggles when servicing the refrigeration circuit
* Beware of hot surfaces on refrigerant circuit components
* Beware of sharp edges on sheet metal components
* Use care when recovering or adding refrigerant
6. Use COMMON SENSE - BE SAFETY-CONSCIOUS
This is the safety alert symbol . When you see this symbol on the air conditioning unit and in the
instruction manuals be alert to the potential for personal injury. Understand the signal word DANGER,
WARNING and CAUTION. These words are used to identify levels of the seriousness of the hazard.
DANGER Failure to comply will result in death or severe personal injury and/or
property damage.
WARNING Failure to comply could result in death or severe personal injury and/or
property damage.
CAUTION Failure to comply could result in minor personal injury and/or property
damage.
IMPORTANT Used to point out helpful suggestions that will result in improved
installation, reliability or operation.

Chapter 1: Description & Specifications
1.1 Foreword
Note: All operation of this unit shall be performed by qualified persons such as engineers
and technicians.
This manual shall only be used as the guide for the installation and operation of the ICE
EX Series Cabinet Climate Control Units. It introduces the installation, operation and
regular maintenance of the unit.
1.2 General Description
The EX Series heat exchanger is designed for outdoor telecommunication or control
cabinets. It is designed for easy installation and reliable operation. The heat exchanger can
be operated immediately after installation. And the output can be automatically adjusted
when internal heat load changes, any fault can be read remotely through the RS485 interface
monitoring system.
The EX Series heat exchanger works as shown in Figure 1, the unit’s internal loop draws
heated air from upper opening, the heat dissipated to the outside air in the heat exchanger.
The external loop draws cold air from lower end and discharges the hot air from the upper
opening.

IMPORTANT
The air conditioner shall be kept vertically strictly in accordance with the
instructions on the package during transportation, storage and use.
Power Input
DC input power: The normal operating voltage is -40 ~ -58V, The unit can be safely
operated between -38 ~ -60V.

2.1 Unpacking and Inspection
All of the EX series heat exchangers are carefully packaged for shipping and storage.
Unpack the carton and remove the unit from the shipping materials. Check the packing
list to ensure all parts and components are present.
Note:
1. Please check for any damage to the packaging and units; if any is present, make a
note and inform Industrial Climate Engineering together with the bar code number
on the package within 7 days.
2. If the product will not be immediately installed or is to be forwarded to its final
destination, re-pack the unit and store it in a safe place.
3. As an environment concern, we recommend that all shipping cartons be recycled.
2.2 Preparation Before Installing
The cabinet should have filters for the external loop to prevent the dust from entering the
heat exchanger.
The external loop’s suction and discharging opening should be isolated. If the suction and
discharging air is short circuited, heat dissipation capability will reduced significantly.
The opening area of the cabinet should be at least 1.5 times of the heat exchanger’s inlet
and outlet opening area and directed toward the heat exchanger’s opening.
During normal operation, the heat exchanger’s external loop will draw in small amounts of
water. This water can be discharged from the heat exchanger by a drainage pipe. If the heat
exchanger is mounted inside the cabinet, the drainage pipe should be designed carefully,
and the pipe should not be twisted. And when the pipe is exposed to ambient lower than
32ºF (0ºC), care should be taken to prevent the pipe from freezing.
