3. Installation and Debugging
Attention!
Read this chapter before installation. Install the machine according to
following steps!
Air-cooled water chiller should be installed in an environment that has good
ventilation, such as draughty area near the window. Ambient temperature
should not be more than 43℃ if it is installed indoors. Use ventilator or exhaust
pipe to conduct the hot air produced by the chiller to the outside. If the chiller is
installed outdoors, protective cover should be used.
3.1 Installation Notices
1) Make sure that the voltage and frequency corresponds with the requirements
on manufacturer's name plate.
2) Connection of the machine electrical wires and negative wire according to
local rules and regulations.
3) Use independent electrical wires and switch. Diameter of electrical wire
should not be smaller than that of the electric wire which is used for the
electrical control box.
4) Wiring connections should be firmly fixed.
5) The chiller use three phase & five core wire. Connect wire N to null wire, G to
earth wire, and others to live wire.
6) Power supply:
Voltage deviation: Rated voltage on the nameplate: ±5%
Frequency deviation: ±2%
7) According to the installation configuration diagram to install the pipe system,
and use thermal insulation materials to protect the refrigerated water pipe.
8) At the lowest part of cooling water circulation, drainage valve should be
installed.
9) Water filter should used in the cooling water and chilled water circulation pipe
if water quality and surroundings of cooling tower is bad.
10) After the installation is completed, check if there are leakages in the
circulation system. Cooling water circulation pipe should be covered with a
layer of insulated material to avoid temperature increasing and water drops
