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.
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 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. The water coil
is connected via connections with dimensions
DN15 (1/2’’), outside thread, inside the unit.
Knockouts are placed on the top and the side of
the unit.
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.
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°). The hatch must be held when the
snap fixings are loosened. See fig. 3a and 3b.
3.
After service, repairs and maintenance close
the service hatch and make sure that the
snap fixings lock securely.
Unit with electrical heating
The unit is connected via the cable gland on
one side of the unit or its top. Pierce the gland
with a screwdriver before entering the cable.
Control (230V~) and power supply for heat
(400V3~) should be connected to a terminal
block in the terminal box.
The cable glands used must meet the
protection class requirements. The largest cable
diameter for the terminal block is 16 mm².
See wiring diagrams.
Maintenance
Unit with water heating
The appliance filter should be cleaned regularly
to ensure the air curtain effect and heat
emission from the device. How often depends
on local circumstances. A clogged filter is not a
risk, but the appliance function can fail.
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°). The hatch must be held when the
snap fixings are loosened. See fig. 3a and 3b.
3.
Remove the filter and vacuum clean or wash
it. If the filter is clogged or damaged, it may
need to be changed.
