CAUTION!
In
the
case
of
power
failure,
once
power
supply
is
restored,
the
controller
returns
to
the
operating
status
it
had
before
power
failure.
A
power
outage
may
not
protect
the
components
connected
to
the
controller
from
damage,
e.g.
when
water
heat
exchangers
are
powered
and
controlled
directly
from
the
controller.

Changing
parts
or
components
Changing fuses
CAUTION!
Changing
overcurrent
protections
built
into
the
device
should
be
performed
in
consultation
with
the
manufacturer.
Use 230V mains fuses, time-delayed, porcelain, 5x20mm. Fuses in the output circuits of fans and heaters should be selected,
depending on the loads present in the network. By default, fuse F1 (power supply input of the controller and ground heat
exchanger outputs, SBP1, SBP2) is 6.3A. Fuses of a lower voltage rating are permitted, if the total load present in these
circuits is lower.
The table below shows the approximate rating values for a fuse, depending on the load.

Changing the control panel
CAUTION!
When
changing
the
control
panel,
make
sure
that
its
program
is
compatible
with
the
program
in
the
controller
module.
5.6.12
Record
of
modifications
CAUTION!
The
manufacturer
reserves
the
right
to
introduce
improvements
and
modifications
to
the
products.
5.7
Drainage
of
condensate.
During assembly, pay attention to the position of the drain nozzle that evacuates condensate from the drip tray. The position
of the device shall ensure free access to the drain nozzle, and enable connecting a drain trap and a drain pipe, at the correct
angle. As a standard, the recuperator is equipped with an automatic drain trap, which does not require periodic pouring of
water.
CAUTION!
Failure
to
properly
trap
the
condensate
drained
from
the
device
will
result
in
the
sucking
in
of
air
from
the
sewage
system,
and
will
prevent
proper
draining
of
the
condensate
from
the
recuperator.
This
can
lead
to
the
overfilling
of
the
drip
tray
and
damage
to
the
unit.
