Water pipe installation
Installing strainer
Install strainer (Field scope: 50 Mesh) that is
serviceable for cleaning at the inlet of DVM CHILLER
to prevent foreign substances such as bolts and
stones from flowing into water side heat exchanger.
- If strainer is not installed or the mesh is too
wide, foreign substances may flow into the
system and cause damage by freezing.
Install drain valves at inlet/outlet pipes to drain water
from water side heat exchanger for services.
Install extra strainer that is serviceable for cleaning
near inlet pipe of the water pump.
Maintaining circulating water amount
If the product is operated below minimum amount
of circulating water (more than 50 % of rated flow
rate), plate type heat exchanger may freeze and be
damaged. Use the product within recommended
circulating water amount.
Maintain water level since it may decrease by
blocked strainer, remaining air, malfunction of
circulating pump.
Drainage during winter time
When DVM CHILLER is not operated during winter
time, drain all water by opening drain valves in
CHILLER shown in figure.
Drain valve
CAUTION
Be careful that because the water inlet pipe has no
drain plug, a small amount of water may come out
from the pipe when the coupling is disassembled.

Air venting
Vent air by opening two air vent valves on inlet and
middle of the pipe of water side heat exchanger.
If air venting is not done properly, it is difficult to
maintain rated flow rate, and pipe corrosion or noise
by remaining oxygen may occur.
Air vent valve
When venting air, be aware to prevent water get in
to the box.
Solution for freeze protection device
When freeze protection device is activated, plate heat
exchanger may freeze. Operate the product after
taking care of the cause. If you operate the product
before the problem has been taken care of, plate type
heat exchanger will be frozen and damaged, causing
refrigerant leakage or water may enter into the
refrigerant cycle.
Solution for pump vibration noise
Install flexible joints at inlet/outlet and use vibration
proof rubber on the pump since noise may occur when
pump vibration is transferred to pipes.
