Condensation water
drain
ERS 20 can produce several litres of condensation water
per day. It is therefore important for the condensation
outlet to be correctly executed and for the ventilation
heat exchanger to be installed horizontally.
Check that the water seal is airtight and firmly in posi-
tion. The connection must be made so that the user can
check and top up the water seal, without opening ERS
20.
CLEANING THE CONDENSATION WATER
DRAIN
Condensation forms when ERS 20 is working. This
condensation is led off and collected in the condensation
water drain. Apart from water, a certain amount of dust
and particles also collect there.
Check regularly that the condensation water drain and
any floor drains are not blocked; water must be able to
run through freely. Clean, if necessary.
NOTE
During operation, negative pressure arises in
the ventilation heat exchanger, which means
that a water column of at least 100 mm must
be guaranteed in the water seal.
