3.4 OPTIMUM OPERATION
Observe the following precautions to ensure the system oper-
ates.
• When the display shows “ ”, ask a qualified service
person to clean the filters (Refer to “4 MAINTENANCE”).
• Do not operate the Heat Reclaim Ventilator 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-GBMV1 series only)
• The life of humidifier become shorter when the supply
water is hard water. (VKM-GBMV1 series only)
Use a water softener.
• Do not install the remote controller where the indoor
temperature and humidity, respectively, are out of the
range of 0-35°C and RH 40-80%.
This may cause malfunction.
• Do not install the remote controller where direct sun-
light may fall on it.
This may cause discoloration or deformation.
NOTE
• When the solenoid valve fails, the remote controller does not
display any error code.
Usage under that status will lead to insufficient humidification
and increased tap water consumption.
The solenoid valve should be checked at the beginning of the
heating season. (VKM-GBMV1 series only)
4 MAINTENANCE
(for a qualified service person only)
ONLY A QUALIFIED SERVICE PERSON IS ALLOWED TO
PERFORM MAINTENANCE
