4.2 Optimum Operation
Observe the following precautions to ensure the system operates.
• When the display shows “ ”, ask a qualified service person to clean the filters (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.
• 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 sunlight may fall on it.
This may cause discoloration or deformation.
Note • When the fan motor fails, the remote controller does not display any error code.
Usage under that status will lead to insufficient ventilation.
The air supply and exhaust fans should be checked once every one or two months.
You can make a simple check such as below way.
To check the wind flow, hold a bar of which the end has a string or other similar lightweight item over the
supply grille and exhaust grille.
For remote controllers which display the filter sign, turn on the power after maintenance, and press
the filter sign reset button.
