Air-cooled water chillers should be installed in an environment that has good
ventilation, such as draughty area against the window. Ambient temperature
should not be more than 35
if it is installed indoors. Use 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.
1). Make sure that the voltage and frequency corresponds with the
requirements on manufacturer's name plate.
2). Connect the machine with electrical wires and negative wire according to
local code.
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 chillers use three phase & five core wire. Connect wire N to negative
wire, PE to earth wire, and others to live wire.
6). Power supply:
Voltage deviation:
10%
Frequency deviation: 2%
7). Piping system should be installed according to the schematic drawing of
installation. Use insulated material to protect the cold water pipe.
8). Circulation pipe diameter of the pump should not less than that of
condenser inlet pipe. Circulation pipe with larger diameter should be used
for long distance transportation of process water.
9). Automatic exhaust tap should be installed at the top of circulation pipe,
and at the lowest part drainage valve should be installed.
10). Water filter should used in the process water and cooling water circulation
pipe if water quality and surroundings of cooling tower is bad.
11). After the installation is completed, check if there are leakages in the
circulation system. Cold water circulation pipe should be covered with a
layer of insulated material to avoid temperature increasing and water
drops forming on the surface of circulation pipe.
