Mounting
When mounting, please use foundation bolts or expansion bolts to fasten the unit with foundation supporter.
It is advisable to pad the unit bottom against foundation by using vibration absorption rubber to prevent
noise and vibration.
Chilled Water Piping
Chilled water piping must be insulated and waterproof to avoid performance loss and moisture condensing
on it.
To guarantee the chilled water quality, the water strainer shipped with unit must be installed on the chilled
water in pipe.
Both chilled water inlet and outlet port are external taper thread connections.
When performing water pipe connection, use gripping pliers to fix the unit connections to avoid the reserved
connections on unit being directly suffered from revolving torque when fastening.
Air vent valve should be installed at highest points on chilled water piping system, see detailed information in
“chilled water system installation schematic diagram”. After completing chilled water piping, carry out leak
detection and 0.4MPa pressure test to ensure having no fault, then fully fill water in system, open air vent
valve, purge all the air trapped in the piping system, after that shut off the air vent valve. Water drainage
valve should be installed at lowest points on chilled water piping system.
In order to achieve the unit long-life operation, it is recommended to give first priority to new type plastic
water pipe such as PP-R, PVC, never use galvanized steel pipe when choosing the material of water pipe.
Caution:
•
The accessory strainer shipped with unit must be installed on water in pipe, otherwise failure of the unit
may be caused.

•
Never put the chiller into the condition of being operated with very oily, salty or acidic water, because
these substances may lead to capacity drop and unit damage. Be sure to use clean water when filling in
the water circuit to avoid heavy corrosion and choking of the system.
•
Don’t use the water pump equipped in unit to clean piping. If using the pump to clean is required, you
can fill clean water in system at water in side, meanwhile make the pump running, please conduct 30-
minute pump operation, then clean the strainer.
