13. It is recommended to clean finned condenser every 3 months. In the case of using finned
condenser in high-temperature, high-humidity or greasy environment, please shorten the
cleaning period based on actual filth blockage conditions.
14. If there is just little dust and batting in finned condenser, use compressed air to blow
out dust and batting, and pay attention to not touching fins.
15. If there is much oil dirt or it is seriously scaled on surface of finned condenser, please
clean with cleaning agent dedicated for air conditioner.
16. If water chiller has not been used for a long time or stopped in an environment lower than
2°C for a long time, drain out water inside the equipment based on the following steps and
ensure machine dryness.
a) Make sure that the water chiller has been stopped and deenergized, close the water inlet and
outlet ball valve, and dismantle water pipes connecting air chiller and the host machine;
b) Open drain valve and water inlet and outlet valves at bottom of water tank of water chiller to
drain water in the water tank;
c) Screw off drainage plugs at bottom of water pump with spanner to drain out water in the
water pump;
d) Blow in compressed air from the water outlet of water chiller and maintain a certain pressure,
screw on the plugs after there is no water flowing out from the drainage plug, then
respectively blow in compressed air from water inlet and outlet and maintain a certain
pressure for 1 minutes to make sure that water in hose has been blown to the water tank;
e) For water chiller with water filter, disassemble water filter and take out the filter element, and
install back the element after drying the element and inside of water filter with compressed
air;
f) Close the drainage ball valve and water inlet and outlet ball valves after there is no water
draining out from the water drainage outlet of the water tank;
g) If water chiller is equipped with internal circulating pump, it is necessary to screw off the
drainage plug at bottom of circulating water pump with spanner, drain out all water in the
internal circulating pump, and screw back the plug.
17. Water chiller shall be replaced at least every 6 months, which cannot use tap water, but
purified water or distilled water. Add some anticorrosive agent and agitate if possible;
18. Water pump has to be operated after draining out air every time the water is replaced.
Operation before drainage is strictly prohibited;
7.12 Maintenance of voltage-stabilized power source
Regularly check operation conditions of voltage-stabilized power source, which may be
conducted from the several following aspects:
1. Check whether temperature rise of compensation transformer and voltage regulating
transformer work normally, and whether the load exceeds the rated value;
2. Whether input voltage goes beyond the regulated range;
3. Whether the voltage regulating system and transmission system (including transmission
chains) operate normally;
