B.1.4.1.
Main
Pipes
Connections
Make
sure
the
diameter
of
the
water
pipes
fits
and
is
not
less
than
the
diameter
of
the
connection
on
the
unit.
When
connecting
the
water
pipes
to
the
coil,
take
care
not
to
damage
the
coil
manifold.
During
this
operation,
hold
the
coil
connections
firm
with
spanner
to
avoid
damaging
them.
The
fittings
are
located
on
the
side
of
the
unit.
B.1.4.2.
Condensate
Water
Pipe
Connection
This
operation
must
be
carried
out
with
particular
care.
The
unit
is
fitted
with
a
gravity
drainage
condensate
drain
pan
with
an
open
connection
on
the
back
of
the
unit.
The
pipe
should
have
an
internal
diameter
of
at
least
16
mm.
The
drain
connection
has
an
external
diameter
of
18
mm.
Proceed
according
to
the
following
instructions
(see
figure
above).
1.
Connect
the
condensate
drain
hose
to
the
pan
outlet
with
a
hose
clip.
2.
Make
sure
the
drain
pipe
has
a
slope
of
at
least
2
cm/m
without
obstructions
or
bottlenecks.
3.
Fit
a
siphon.
By
eliminating
the
pressure
drop
caused
by
the
fan,
this
prevents
air
being
sucked
up
the
drain
hose.
4.
Connect
the
condensate
drain
pipe
to
a
rainwater
drainage
system.
Do
not
connect
to
the
sewage
system
as
odors
may
be
drawn
in
if
the
water
in
the
siphon
evaporates.
5.
After
connecting
the
piping,
check
that
the
condensate
drainage
is
working
correctly
by
pouring
water
into
the
pan.
B.1.4.3.
Air
Purging
After
connecting
the
water
inlet
and
outlet
pipes
to
the
main
supply
lines
turn
on
the
main
breaker
and
operate
the
unit.
1.
Open
the
water
inlet
valve
and
flood
the
coil.
2.
Check
all
connections
for
water
leakage.
If
no
leak
is
found,
open
the
air
vent
valve
with
an
open
end
wrench.
Then
purge
the
air
trapped
inside
the
coil.
When
performing
thisactivity,
take
care
not
to
touch
the
electrical
parts.
3.
Close
the
air
vent
valve
when
no
bubbles
appear.
4.
Open
the
water
outlet
valve.
IMPORTANT
Gravity
drainage
may
be
converted
into
forced
drainage
by
fitting
a
condensate
drain
pump
that
is
available
as
an
accessory.
