OPTIMUM OPERATION
Observe the following precautions to ensure the system operates.

•
(Refer to MAINTENANCE).
•
Do not operate the HRV unit in Bypass mode when the room air is under heating in winter or
when the outside temperature is 30°C or higher.
This may cause condensation to form on the main unit or on discharge grill, or around air supply
opening.
•
Keep the indoor unit and the remote controller at least 1 m away from televisions, radios,
stereos, and other similar equipments.
This may cause distorted picture or noise.
•
Turn off the main power supply switch when it is not used for long periods of time. When the
main power switch is turned on, some watts of electricity is being used even if the system is not
operating.
Turn off the main power supply switch for saving energy. When reoperating, turn on the main power
supply switch 6 hours before operation for smooth running.
•
Use city water or clean water and take steps to prevent condensation from forming. (VKM-

out of the range of 0-35°C and RH 40-80%.
This may cause malfunction.
•
Do not install the remote controller where direct sunlight may fall on it.
