Check the water lock for condensation water
The water seal must be checked at least once a year, ideally in the au-
tumn.
The water seal is located outside ERS 20. Contact your installer if you
are unsure of where to find it.
No condensation water is generated in the HRV unit during the warm
period of the year and the water seal will dry out.
During the colder parts of the year, ERS 20 can produce several litres of
condensation water every day. If the condensation outlet is not working,
this may cause water damage inside the home.
The water seal must not dry out during this part of the year, because air
will be drawn into the HRV unit due to the negative pressure in the unit,
which will then prevent the condensation water from running out.
1.
Check that the condensation drain and the water seal are not clogged
with dirt.
2.
Pour approx. one litre of water into the water seal.
3.
Check that the water runs through unobstructed.
Cleaning the heat exchanger
Check the heat exchanger every other year and clean if necessary. Avoid
contact with the fins.
Caution
Do not damage the fins. If you are unsure, contact your installer
for help with cleaning.
1.
Remove the four screws holding the heat exchanger.
2.
Remove the trim and the metal rail.
3.
Carefully lift out the heat exchanger.
4.
Clean the heat exchanger carefully, e.g. with a vacuum cleaner. If
necessary, you can use warm water and mild soap.
Carry out assembly in reverse order.
