Dear Customers:
Thank you for choosing Cooper&Hunter air-cooled closed control air conditioner. Please read this manual
carefully before installation and operation. Keep it well for reference so that you can master and operate the
unit correctly.
Safety Notices
Warning! : It means that incorrect operation may cause casualty or badly harm to people.
Caution! : It means that incorrect operation may cause harm to people or damage to property.
Warning!
1. Please have the unit installed by authorized service center. Improper installation will cause water
leakage, electric shock and fire, etc.
2. Don’t use or store flammable or explosive substance around the unit.
3. When malfunction occurs (such as burning odor), please cut off power supply at once.
4. Don’t insert finger or things into air exhaust vent or air inlet grille.
5. Don’t start or halt the unit by inserting or pulling out power cord
6. Don’t refit the unit. Please contact our dealer or professional installation personnel when it is
necessary to repair or move the unit.
Caution！
1. Please check if power supply complies with power requirement listed on nameplate and also check
power safety before installation.
2. Please check and confirm if wire and pipeline are connected correctly to prevent water leakage,
electric shock and fire.
3. Power supply socket must be grounded reliably to guarantee effective grounding of the unit and
prevent electric shock. Do not connect the grounding line to gas pipe, water pipe, lightning rod or
connection wire of telephone.
4. Don’t operate the unit with wet hand and don’t allow unprofessional personnel to operate it.
5. Turning on and turning off indicated in the instruction are the operation to the ON/OFF button on
controller. Cutting off the power is the stop of power supply to the unit.
6. Please don’t expose the unit directly in corrosive environment with water or dampness.
7. Do conduct electric leakage test after installation.

as above.
By compressor used for cooling and dehumidifying, electric heater for heating and temperature
adjustment, infrared humidifier for humidifying and logical program for controlling the even running of each
functional part, the unit adjusts the ambient temperature and humidity so that it can meet the requirement of
maintaining the precise temperature and humidity.
When the unit is running, the flowchart of refrigerant system is as below:
Scroll compressor Air cooled condenser Liquid filter Expansion valve Liquid separator
Evaporator Scroll compressor.
Airflow direction of air supply system:
Return air Plate type filter Evaporator Humidifier Electric Heater Centrifugal fan

3.3 Requirements of Installation
Produced in the strict quality management system of our company, tested strictly, and installed,
debugged, operated as well as maintained according to this manual, the unit can work in proper state whose
working life can also be lengthened. In order to ensure the normal running and prevent the malfunction of

18
the unit, the installation must be executed by experienced technicians with the knowledge of air conditioner.
And also, this part of the manual must be read carefully before installation.
If this system is to be used in strong magnetic field or places with high degree of alkaline or acidity or
extremely unstable voltage, in order to guarantee product’s working life and reliability, some special
treatment may be needed. In this case, please contact us as soon as possible.
For good running of the unit, the installation has to comply with the following rules.
3.3.1 Requirements of Installation for Indoor Units
(1) The refrigerants have been filled in indoor units before outgoing. Move and installation shall be
cautious and the inclination pitch cannot be greater than 45°, let alone inversion.
(2) Installation of the unit shall completely meet the requirements of heat exchange and space for
maintenance, and also shall take the convenient pipes connection between indoor and outdoor units into
account.
(3) Don’t install the unit in the place with corrosive gas, intensive dust, salt mist, oily fume or in the
extreme wet site.
(4) Don’t install the unit in places that store the flammable or explosive substance, or leak the
flammable or explosive gas.
(5) The location of the unit has great influence on the ambient temp. and humidity of the machinery
room. On the permission of the project, it shall be close to the spot of the maximum loading as much
as possible and shall make sure that the return air can be unobstructed and the supply air can be
evenly distributed.
(6) The unit shall be installed on the flat concrete foundation with the steel flat base on which the rubber
sheet of 15mm thickness is paved.
(7) Make sure that the ground is horizontal and the inclination pitch cannot be greater than 1°.
(8) Make sure that the drainage of condensate water and humidifier are smooth. Due to the possibility
of high temperature (maximum temp. could be 100 ) of drain water℃of humidifier, please pay attention
to the security of the drainage.
(9) When the unit is installed on the bracket whose height is adjustable (the type of bottom air supply),
the unit and the bracket shall be fixed by bolts and the joint face shall be paved with the rubber
damping mat.
3.3.2 Requirements of Installation for Outdoor Units
(1) Refrigerant has been charged inside the outdoor unit before leaving factory, therefore, be careful
when moving the unit or during installation.
(2) Outdoor unit must be securely installed on steady and strong supportive place outside the
constructions.
(3) Outdoor unit and indoor unit should stay as close as possible so as to shorten the length of cooling
pipes and reduce the number of bent pipes.
(4) The locating place must be strong enough to support units’ weight and well prepared for noise
muffling and vibration damping so that noise and the discharged air won’t affect neighborhoods
when the unit is operating.
(5) There should be good air circulation and enough space for air intake and maintenance and no
