high
dust
levels
in
the
air,
it
is
recommended
to
check
the
condition
of
the
filter
cloth
more
frequently.
CAUTION!
When
inspecting,
make

has
been
torn
(e.g.
from
excessive
soiling).
CAUTION!
Regular
changing
of
filters
is
essential
to
maintain
the
correct
performance
parameters
and
energy
efficiency
of
your
system
.
CAUTION!
Recuperators
with
the
nominal
capacity
of
<1000m3/h
are
equipped
with
a
filter
change

In
recuperators
with

7.2
Heat
recovery
system.
The condition of the heat exchanger should be checked once every six months. If necessary, clean the heat exchanger with
compressed air or a vacuum cleaner. In addition, check the following: the level of soiling in the condensate tank; whether
the water trap is unobstructed and filled with water; and whether that the bypass damper rotates freely.
7.3
Electric
heater.
The level of soiling in the heater should be checked on a quarterly basis. This operation may only be carried out, when power
supply to the unit has been disconnected. If necessary, clean the heater with compressed air (directing its flow in the
opposite direction to the normal direction of air flow and parallel to the lamellas), or using a vacuum cleaner with a soft
suction cup. The heater is an electric device subject to periodical inspection, in accordance with applicable regulations.
