Daily inspection management
1
Water quality management
To prevent corrosion or scale accumulation in the plate type heat exchanger, you have to take a special
caution for water quality management.
2
Flow amount management
If the flwo amount is insufficient, freeze and burst may occur in the plate type heat exchanger.
3
Brine concentration management
If Brine(antifreeze) is used in the heat source water, use the designated type and concentration.
Operation Tips
• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air
conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.
