Start-up (E)
When the unit is used for the first time or after
a long period of non-use, smoke or an odour
may result from dust or dirt which has collected
on the element. This is completely normal and
disappears after a short time.

) 2 m and 2.5 m units can be connected with two
power supplies. The 2.5 m unit has electric coils with two
different outputs, and the coil to the left, on the horizontal
unit, viewed from inside the premises, has the highest
output.
*) Dimensioning of external wiring shall comply with
applicable regulations and local deviations may occur.
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.
To access the connections the service hatch and
intake grille must be opened. The water coil
is connected via connections with dimensions
DN20 (3/4’’), inside thread, inside the unit.
Knockouts are placed on the top and the side of
the unit. Hoses are mounted via cable glands at
knockouts to protect the hose and prevent air
leakage. See Fig. 6. Flexible hoses are available
as accessories.
Note! If you want to divide the output
between two connection points, the series
cabling must first be removed (ARFEC4220/25,
2x400V3~). See wiring diagrams.
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”.
Adjustment of the air curtain and airflow
The direction and speed of the airflow should
be adjusted considering the load on the
opening. Pressure forces affect the airstream
and force it inwards towards the premises
(when the premises are heated and the
outdoor air is cold).
The airstream should, therefore, be directed
outwards to withstand the load. Generally
speaking, the higher the load, the greater the
angle required.
Basic setting fan speed
The fan speed when the door is open is
set using the control. Note that the airflow
direction and the 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.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. The service hatch is opened by loosening the
snap fixings located on the bottom of the unit
(turn 90°). See Fig. 3.
3. After service, repairs and maintenance close
the service hatch and make sure that the
snap fixings lock securely.
NOTE: Care must be taken when
connecting the pipes. Use a pipe
wrench or a similar tool to grip the air curtain
connections to prevent straining of the
pipes and subsequent water leakage during
connection to the water supply pipe-work.
The connections to the heating coil must be
equipped with shut off valves to allow trouble-
free removal.
Water coil is equipped with a drain and a vent
valve.
Maintenance
Since fan motors and other components are
maintenance-free, no maintenance other than
cleaning is necessary. The level of cleaning can
vary depending on local conditions. Undertake
cleaning at least twice a year. Inlet and exhaust
grilles, impeller and elements can be vacuum
cleaned or wiped using a damp cloth. Use a
