Delivery and handling
Assembly
ERS 30 must be placed on a stable surface to minimise the
risk of vibrations.
•Wherever the unit is located, any joists that back onto a
sound-sensitive room should be fitted with soundproofing.
•Condensation water comes from the HRV unit. A condens-
ation outlet with a water seal must be installed and routed
to an internal drain.
•The HRV unit’s installation area always has to have a
temperature of at least -25 °C and max. 50 °C.
INSTALLATION AREA
Leave a free space of 600 mm in front of the product.
600
NOTE
Ensure that there is sufficient space (300 mm) for
connecting ventilation ducts.

Condensation water drain
ERS 30 can produce several litres of condensation water
per day. It is therefore important that the condensation
outlet is correctly executed and the HRV unit installed hori-
zontally.
Check that the water seal is airtight and firmly in position.
The connection must be made so that the user can check
and top up the water seal, without opening ERS 30.
The connection for the condensation outlet measures Ø15
mm.
If the HRV unit will be installed in a cold area, the condensa-
tion water drain pipe must be insulated so the condensation
water in the pipe does not freeze. It is also recommended
that the water seal is mounted in a warm area to guarantee
that the water in the water seal does not freeze. If it cannot
be guaranteed that insulation will protect the condensation
water drain pipe against frost, a thermostat-controlled
heating cable must be installed around the condensation
water drain pipe. The installation from the water seal to the
drain must be carried out with a requisite slope of at least
1 %.
CLEANINGTHECONDENSATIONWATERDRAIN
Condensation forms when ERS 30 is working. This condens-
ation 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
HRV unit, which means that a water column of at
least 100 mm must be guaranteed in the water
seal.
