Installation and Debugging
Please read this chapter carefully before installation, and you must
install the machine according to the following procedures!
Before installing the chiller, please design the pipe system reasonably, lay out
the position of injection mould machine and cooling water tower to make the
repair and maintenance convenient, the installation of chiller should be
convenient to operate and keep appropriate distance from cooling water tower.
The cooling water tower should be installed in the open air, and make sure that
the cooling water tower is placed in the environment with good ventilation to
release contamination and gas; If the cooling water tower is located in factory,
the exhaust fan should be installed to keep air circulating. As the discharged air
can contain a great deal of water content, the work capacity of the switches and
controllers could be influenced if the exhaust fan is installed too close to the
machine.
3.1 Installation Notice Items
1) Make sure that the voltage and frequency of the power comply with
specification on the nameplate.
2) The wiring and grounding should comply with local regulations.
3) Use independent cable and power switch, the diameter of the cable should
be no less than cable used in the electrical control box.
4) The terminal post of the cable should be firm and safe.
5) The chiller of this series should use three phases and five lines, the power
supply connects the power supply wire under voltage, (N) connects the zero
line, (G) connects the earth wire.
6) Power distribution requirements:
The electric voltage of main power supply:
±
10%
The frequency of main power supply:
±
2%
7) Install pipeline working system according to the wiring installation diagram,
and use thermal insulating materials to protect the refrigerated water pipe
line.
8) Choose appropriate cooling water tower according to the refrigeration
capability of the ice water machine.
