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 airow
direction and the fan speed may need ne
adjustment depending on the loading of the
door.
Filter (W)
The unit is not equipped with an internal lter.
The water coil can be cleaned by loosening
the motor section (see Opening the unit). An
external lter is available as accessory which
provides an easier maintenance, since the unit
does not need to be opened. The external lter
is easily fastened with the four supplied velcro
stickers. If the lter is clogged or damaged, it
may need to be changed.
Opening the unit / Service, repairs and
maintenance
For all service, repair and maintenance rst
carry out the following:
1. Disconnect the power supply.
2. Loosen the motor section on the unit's top
(horizontal), back (vertical) by removing its
screws.
3. Fold the section towards the cable side.
NOTE: Be careful to prevent the section from
falling.
4. After service, repairs and maintenance, put
the section back in reverse order.
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
brush when vacuuming to prevent damaging
sensitive parts. Avoid the use of strong alkaline
or acidic cleaning agents.
Temperature control
Temperature control of FC maintains the
exhaust temperature. Should the temperature
exceed the preset value, the overheating alarm
will activate. For more information see the FC
manual.
Electrical installation
The installation, which should be preceded by
an isolator switch with a contact separation
of at least 3 mm, should only be wired by a
competent electrician and in accordance with
the latest edition of IEE wiring regulations.
The air curtain has an integrated PC board
which is connected to the selected external
control system FC. FC must be ordered
separately. The PC board is located in the
terminal box on the unit's long side. FC is
supplied pre-programmed. Communication and
sensor cables are connected to the PC board.
Should more than one air curtain be
controlled by a single FC, an additional
communication cable FCBC per unit will be
required. See manual for FC.
The electrical connection is made on the top
of the unit (horizontal) or on the back (vertical).
Tarta is equipped with a 1,8 m cable without
plug.
Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium ns 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 the long
side of the unit via connections DN25 (1’’),
external thread. Flexible hoses are available as
accessories.
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.
The water coil is equipped with vent valves.
Adjustment of the air curtain and airow
The direction and speed of the airow 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
