Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. The front hatch is removed by removing
the screws on the top of the unit and then
detach the bent edge at the bottom. (Fig.3)
3. After the service, repair and maintenance
reattach the front hatch. Place the hatch
at the lower edge with the bent edge and
fasten on top with screws.
Note that when carrying out work where the
end is removed, the outlet grille also detaches.
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.
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.

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.
Note that the unit shall be preceded by a
regulating valve, see Frico valve kit.
The water coil is connected on top of the unit
via steel pipes with DN20 (3/4’’) terminals,
external thread. Flexible hoses are available
as accessories, see accessories pages.
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
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.
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.
