Cycle under normal temp. (A):
(Capacity of co Capacity of pipe+ Capacity of container)×1/3(Thickness of detergent 33%)
Cycle under normal temp. (B):
(Capacity of flume of cooling tower+ Capacity of co Capacity of pipe)×1/10(Thickness of
detergent 10%)
When cleaning after the unit stops, the capacity of the cooling tower flume can be 1/2 or 1/3 of rated
value. When you do cleaning during running, the capacity should achieve the rated value.
Precautions on using detergent
When cleaning, wear rubber gloves and do not expose your skin or your clothes to detergent. If you
touch the detergent, wash it off with clean water.
The container for detergent should be made of plastic or glass and not lead. The used detergent should
be neutralized with lime or soda before draining
Detergent is harmful. Keep it away from children.
Turn on the unit after cleaning to ensure it is clean, clean it again.
c) Precautions for chemical cleaning
When you clean, wear rubber gloves and do not expose your skin or your clothes to detergent. If
you touch the detergent, wash with it off clean water immediately.
The container for detergent should be made of plastic or glass and not lead.
Used detergent should be neutralized with lime or soda before draining.
Detergent is harmful, keep it away from children.
Turn on the unit to check the effect after cleaning. If necessary, clean it again.
Water Treatment
Before every start-up, clean and flush the cooling water circuit. Make sure the tower blow-down or
bleed-off is operating. Atmospheric air contains contaminants that increase the need for proper water
treatment. The use of untreated water can result in corrosion, erosion, sliming, scaling or algae formation.
Midea assumes no responsibility for the results of untreated or improperly treated water.
See appendix 1 for water quality requirements.
