Run

heat
exchanger
DVR
A
heat
recovery
system
of
this
type
consists
of
a
heating
coil
in
the
supply
air
‐
flow
and
a
cooling
coil
in
the
exhaust
air
‐
flow.
After
an
extended
running
period
(normally
a
few
years)
dust
particles
can
accumulate
on
the
surface
of
the
coils.
This
can
reduce
the
efficiency
of
the
coils.
Cleaning
must
be
carried
out
with
the
utmost
care
to
ensure
that
the
coil
fins
are
not
damaged.
The
piping
system
must
be
vented
once
a
year
as
air
in
the
system
can
significantly
reduce
the
capacity
of
the
coils.

4.5.1
Pump
and
pressure
expansion
The
service
instructions
issued
by
the
pump
manufacturer
must
be
followed.
The
pressure
expansion
system
must
be
checked
once
a
year.
If
necessary,
the
pressure
must
be
increased
to
the
correct
level.

Condensate
water
drain
Once
a
year
clean
the
drip
tray
beneath
the
heat
exchanger,
as
well
as
the
drain
and
the
water
trap.
Take
care
that
that
there
is
sufficient
water
in
the
water
trap.
If
a
droplet
eliminator
has
been
fitted
to
the
cooling
coil,
this
must
be
checked
once
a
year
and
cleaned
if
necessary.

Heating
battery
Check
that
the
frost
protection
system
is
fully
operational.
A
battery
may
burst
due
to
frost
if
the

protection
system
is
not
operational.

Once
a

clean
the

trap.
Take
