Important notes
1. The best effect is achieved when the unit is used in a well ventilated and dry place, where the unit
takes in 100% fresh air from outside and no re-circulation occurs.
2. Avoid discharging cool air into an closed space. There must be enough space for discharged air,
even use exhaust fans
3. For a place without powered exhaust, 0.8m²of exhaust area is needed for every 3600m³/h air
discharge. When using a powered exhaust, the designed exhaust volume shall not be less than
85% of air intake.
4. Keep the unit away from welding sparks or any source of fire during the installation and when the
unit is running.
5. The unit must be tested and adjusted. E.g.: adjusting water level floats before operation. Ensure
that the unit is operating within the rated electrical currency.
6. Ensure correct wiring of the power and controller. The section in the power socket shall not be
less than 1.5mm². the units shall use a dedicated power line instead of sharing a power line with
other equipments.
7. Voltage of power supply shall be within 10% vibration from the rated voltage. Lower voltage may
cause motor start failure or undue frequent starts and stops. Long-term low voltage or high
voltage will cause damage to the motor.
8. The controller and its wire shall be kept away form strong electronic and magnetic interference,
such as frequency converter, silicon speed and temperature controller, high frequency heater
circuit or high power motor. Avoid wiring the power supply lines parallel to these sources. In the
case of unavoidability, the power line must maintain a distance of more than 30cm from parallel
interference source.
Inspection and preparation before installation
(1) Check the components and documentation (e.g.: instruction, certificate and maintenance card)
against the packing list. If there in anything missing or damaged, keep it as it was and report to the
factory or local distributor.
(2)Check the power supply for correct voltage.
Ways of installation
(1) Cooler can be installed on the outer wall, with a side diffuser (an electromotive swing air diffuser
can be used to cover larger area);
(2) Cooler can be installed on the roof, with a multi-side air diffuser penetrate through the roof and into
the room;
(3) One or more coolers can be installed on the roof or outer wall, each connected to a duct to deliver
the cooled air evenly to the room or to the desired spot;
(4) A number of coolers can be installed on the roof or on the outer wall, connected to a single duct,
and with a powered blower in case of necessity.
