the heat recovery unit to the house sewerage
using a separate removable rubber coupling.
An air trap with a minimum level difference of
250 mm is added in this connection. Above the
air trap, a branch pipe is mounted at a 45-degree
angle. This branch pipe has a cover with a rubber
ring. This can be opened to easily top up the
water trap. This is required to maintain or restore
the water trap.
If the air trap runs dry, the air from the house
sewerage will be able to enter through the unit
and be discharged outside by the discharge ven-
tilator. No smell will be caused but the discharge
capacity will decrease. We recommend refilling
the air trap quarterly. The water will evaporate
more quickly in summer.
When the air trap runs dry, a direct connection
with the house sewerage is created. This creates
smells. Refill the air trap using the fill opening to
solve the problem. Effective discharge of cooking
and baking vapours in the kitchen is guaranteed
by the extractor. The extractor is connected to
the balanced ventilation system.
It is preferable to have a registered installer
carry out the cleaning.
