Maintaining contamination
Small foreign substances in chilled/heating water may
pass through the strainers and may become stuck
or stacked inside plate type heat exchanger. Foreign
substance accumulation inside the plate type heat
exchanger can lead to performance decrease or it may
freeze and and be permanently damaged. Therefore,
clean the plate type heat exchanger periodically.
Turbidity is a standard for water pollution level, and
standard water pollution set by Corrosion Prevention
Association is under turbidity 4. If the turbidity is high
or foreign substance is contamination in too high, clean
the plate type heat exchanger periodically and maintain
the turbidity under 4. If it is over 4, clean the product in
about 1 year after the initial operation of the product.
NOTE
Refer to page 64 for water maintenance standard
table.
Solution for water level decrease
When a tank or thermal storage is installed, select
a pump that can provide required water amount
considering head loss pipe resistance.
CAUTION
The product should be operated for 3 minutes after
it has stopped to protect water side heat exchanger
(plate type heat exchanger) from freezing.
NOTE
Expansion vessel is to buffer expanded water and
also to purge air in water pipes. The capacity of
expansion vessel should be 2 ~ 2.5 times larger
than amount of water expansion or 4 ~ 5 % of total
amount of circulating water.
Freeze protection operation
Forced pump operation may be operated periodically
to protect water side heat exchanger (plate type heat
exchanger) from freezing in winter time or night time
when the pump is stopped. Be careful not to be injured.
Water flow rate range
Refer to the table to maintain minimum amount of
circulating water. If circulating amount is not enough,
the product will not only operate in best performance
but also affect the life of the product. Keep the amount
above the minimum level.
