d) Choose a place which can rigidly support the weight of the unit, this will help to minimize vibration and
noise.
e) The location must not be susceptible to dust or oil to avoid condenser coil being choke by the
contaminant. As the general safety precaution, it is advised that no flammable danger gas should be
located near to the unit.
f) Water source of the cooler must be clean and free from any contaminant such as rusted particles or any
kind of oil. It is necessary to install a water filter in the returning water line.
Installation Pipe Length
The water connection pipes are 1 ¼” BSPT female or 1 ¼” DIN female for both water inlet and water outlet.
The piping network should be designed with as few bends as possible and with as few variations in elevation
as possible. This will reduce the cost of the installation and improve unit performance. The recommended
maximum pipe length for piping insulation is 120 meters. Simple calculation for friction loss of the water head
is needed. It is advised that the minimum pipe size is 1 ¼”.
Caution:
If the chiller is operated under very oily, salty or acidic atmosphere or water, these substances may lead to
capacity drop or failure of the unit.
Be sure to use clean water when filling in the water circuit to avoid heavy corrosion and choking of the
system.
