Do not mount or operate without following the instructions provided in this Manual
and on the mounting template.
During lightning storms, the device must be turned off and unplugged from the
mains.
Do not operate without filters: doing so will allow large dust particles to enter the
heater and fan, which may cause them to fail.
Before mounting, leave the device in a warm room for 2 hours to avoid device failure,
the formation of condensation, or damage to plastic parts after transportation or
storage at low temperatures.
Prolonged exposure to direct sunlight is not allowed for the device.
If you intend to unplug the device, turn it off first using the power button. After 10
minutes, make sure that there is no error indication and only then remove the power
plug from the socket. Otherwise the damper might remain open and outside air will
be able to flow through the device into the premises.
Do not start the filter-life counter until the filters have been replaced with new ones.
Continued use of used filters with the device can lead to impaired performance,
increased fan noise, and device failure.
If the device has been turned off for a long time with the damper open at negative
outdoor air temperatures, then when it is turned on, the device operating parameters
may deviate from the nominal ones and condensation may form on visible and
internal surfaces. To avoid this, it is recommended to perform the following actions
when resuming operation of the device under such conditions:
1. Switch the device to Standby mode.
2. Disconnect the device from the power supply.
3. Wait for the device to warm up to room temperature (at least 1 hour).
4. Wipe the visible surfaces of the device with a dry cloth.
5. Remove the filters and make sure there is no moisture in the device.
6. Blot the formed moisture with a dry cloth
(do not rub the insulation surface to avoid damage).
7. Assemble the device.
8. Connect the device to the power supply.
9. Switch the device to Normal mode.
