Unit with electrical heating
The electrical connection is made on the top
of the unit. See Fig.2. Control (230V~) and
power supply for heat (400V3~) should be
connected to a terminal block in the terminal
box. 2-metre and longer units require dual
power supplies.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
meet the protection class requirements. In
the distribution board it is to be indicated
that ”the air curtains can be supplied from
more than one connection”.
See wiring diagrams.
Start-up (E)
When the unit is used for the first time or
after a long period of disuse, smoke or odour
may result from dust or dirt that has collected
on the element. This is completely normal
and disappears after a short time.
Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium fins and is suitable for connection
to a closed water heating system. The heating
coil must not be connected to a mains
pressure water system or an open water
system.
*) Dimensioning of external wiring shall comply
with applicable regulations and local deviations
may occur.

Note that the unit shall be preceded by a
regulating valve, see Frico valve kit.
The water coil is connected on the upper
side of the unit with ø15 mm smooth copper
pipe with a suitable coupling or soldering.
The connections to the heating coil must be
equipped with shut off valves to allow problem
free removal. Water coil is equipped with a
drain valve. A vent valve should be connected
at a high point in the pipe system.
Air valves are not included. NOTE: Care must
be taken when connecting the pipes. Use
a wrench or similar to hold the air curtain
connections to prevent straining of the
pipes and subsequent water leakage during
connection to water supply pipe-work.
Adjustment of the air curtain and air flow
The direction and speed of the air flow should
be adjusted considering the load on the
opening. Pressure forces affect the air stream
and make it bend inwards into the premises
(when the premises are heated and the
outdoor air is cold).
The air stream should therefore be directed
outwards to withstand the load. Generally
speaking, the higher the load, the greater the
angle that is needed.
Basic setting fan speed
The fan speed when the door is open is set
using the control. Note that the air flow
direction and fan speed may need fine
adjustment depending on the loading of the
door.
Filter (W)
The water coil is protected against dirt and
blockage by an internal air filter which covers
the coil face. In environments where the filter
needs cleaning often, it is advisable to use an
external intake filter (see accessories pages),
which provides an easier maintenance, since
the unit does not need to be opened. When
an external filter is used, the internal filter is
removed.
