6
Check up and adjustment before operation:
1.
Is the cooler installed horizontally?
2.
Is drain pipe connected to the machine?
3.
Is the wat er supply leaking?
4.
Adjust water level in the sump?
5.
Is the power supply connected correctly (particularly for three phase machine)?
6.
Is the power line for the control panel correctly connected?
7.
Is the operation current within the rated range?
8.
Is there unwanted object in the vent?
9.
Is the volt age correct?
10. Does cooler vibrates noticeably while operating?
11. Is there any foreign objects in the sump?
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. A void discharging cool air into an closed space. There must be enough space for discharged air, even
use exhaust fans
3. For a place wit hout powered exhaust, 0.8m² of exhaust area is needed for every 3600m³/h air
discharge. When using a powered exhaust, the designed exhaust volume s hall 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 wat er level floats before operation. E nsure that
the unit is operating within the rated electrical currency.
6. Ensure correct wiring of the power and cont roller. 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 mot or.
8. The controller and its wire shall be kept away form strong electronic and magnet ic interference, such
as frequency converter, silicon speed and temperature controller, high frequency heater circuit or high
power mot or. A void 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.
