3. Extra Hot Water (Immersion Heater):
Most traditional heating systems have an immersion heater to give you extra hot water quickly. This unit
also has an immersion which should be used sparingly to minimise your electric bill.
4. Regularly Clean The Filter: To ensure the unit runs efficiently you will need to regularly clean
the air filter within the unit (at least every three months). When the alarm indication shows follow
the following procedure. You may need to do this more often in a new house.
Clean F370's air filter regularly, how often depends on
the amount of dust in the ventilation air.
When it is time to clean, an alarm indication occurs is
displayed. Factory setting for alarm indication is every
three months.
1. Set the switch to OFF
2. Remove the upper front cover by pulling straight out.
3. Pull out the filter cassette.
4. Take out the filter and shake/vacuum off any dirt. Do
not use water or other liquids for cleaning.
5. Check that the filter is not damaged.
6. Carry out assembly in reverse order.
Even if the filter appears clean, dirt collects in it and this
affects the efficiency of the filter. Therefore, replace it
after 2 years. New filters can be ordered via the installer.
Cleaning the ventilation devices
The building’s ventilation devices should be
cleaned regularly with a small brush to keep the
ventilation. The device settings must not be
changed.
NOTE! If you take down more than one ventilation
device for cleaning, do not mix them up.
Check that the ventilation opening, behind the lower
front cover, is not blocked. Clean if necessary.
To temporarily increase the amount of hot water, first
turn the control knob to mark menu 2 (water droplet) and
then press the OK button twice.
