Pipe
connections
Connection
pipes
on
heating
‐
and
cooling
coils
are
provided
with
external
thread.
Drainage
outlets
on
drip
trays
are
provided
with
external
thread.
i.4.3
Possibility
of
extracting
components
from
the
unit
Pipes
and
cables
must
not
obstruct
the
inspection
doors
and
components
which
can
be
extracted
from
the
unit.
Potential
components
for
extraction
are
filters,
fans
and
rotary
heat
exchanger.
i.4.4
Pipe
connections
to
batteries
i.4.4.1
Heating
coils
Pipes
for
hot
water
must
be
protected
by
insulation
against
frost
and
loss
of
heat.
Further
protection
against
frost
can
be
obtained
by
installing
electrical
heating
wires
around
the
pipes
and
under
the
insulation
combined
with
temperature
sensors
and
a
control
system.
Pipes,
insulation,
electrical
heating
wires,
control
system
for
heating
wires
and
circulation
pump
are
not
delivered
by
Systemair.
i.4.4.2
Cooling
coils
If
ordered
with
the
unit,
the
valves
and
valve
motors
are
stored
in
a
carton
box
placed
inside
the
unit.
Pipes
for
cooling
must
be
protected
by
insulation
against
condensation
on
the
pipes
and
loss
of
cooling
in
the
summer.
Pipes
and
insulation
are
not
delivered
by
Systemair.
i.4.4.3
Rigid
pipe
mounting
brackets
for
valves,
circulation
pumps
and
pipe
system
The
coil
and
pipes
from
the
coil
are
not
constructed
to
withstand
the
weight
and
stress
from
valves,
circulation
pumps,
long
pipes
and
insulation
of
pipes.
The
system
must
be
supported
carefully
in
rigid
pipe
mounting
brackets
to
roof,
floor
and
walls.
i.4.4.3.1
Pipe
connection
to
heating
coils
The
heating
capacity
of
the
coil
with
only
2
rows
is
independent
of
the
connection
of
the
hot
water
in
equal
flow
or
in
counter
flow
to
the
direction
of
the
air,
but
connection
of
the
hot
water
to
the
pipe
marked
for
inlet
and
the
return
water
to
the
pipe
marked
for
outlet
is
very
important
to
ensure
that
the
sensor
for
transmission
of
the
water
temperature
really
will
be
placed
in
a
return
circuit
of
the
coil
(Screw
‐
joint
for
the
water
temperature
sensor
is
welded
in
the
main
collection
pipe
for
return
water).
For
the
frost
protection
of
heating
coil
,
the
water
temperature
in
the
coil
is
transmitted
to
the
controller
The
controller
always
generates
a
signal
to
the
valve
motor
that
keeps
a
sufficient
flow
of
hot
water
to
protect
the
coil
against
frost.
This
frost
protection
is
also
activated
when
the
running
mode
is
“off”.
Coils
with
3
rows
or
more
must
always
be
connected
in
counter
flow
to
the
airflow.
NOTE:
If
glycol
is
added,
the
glycol
must
be
without
additives
and
auto
glycol
must
not
be
used.Automatic
bleeding
has
to
be
installed
at
the
highest
point
of
the
2
pipes
—
supply
or
return
pipe.
If
the
heating
battery
is
built
with
3
or
more
rows,
the
water
flow
must
be
in
counter
flow
to
the
direction
of
the
air.
