Number of motors
Models in the series have different number of
motors. In the production the motors will be
mounted starting from the bottom of the unit,
because it´s most important to protect at the
floor. Therefore it can be empty space above
the motors, at the models that have a smaller
number of motors.
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 louvres 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.
Water connection can be made from above
and below, according to the order key, via
DN25 (1"), internal thread connections.
When connection is made from below, the
connection is placed in altitude between the
first and second motor. Flexible hoses are
available as an accessory, see accessories
pages.
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.
The connections to the heating coil must be
equipped with shut off valves (not included)
to allow problem free removal.
The battery is equipped with bleed valves.
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 distance between the coil plates in
combination with the hole diameter of
the intake grille protects against dirt and
blockage. Which normally makes a separate
filter unnecessary.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power.
2. The service hatch is opened by slackening off
the screws in the side of the unit.
Maintenance
Unit with water heating:
The appliance filter should be cleaned
regularly to ensure the air curtain effect and
the heat emission from the device. How often
depends on local circumstances. A clogged
filter is not a risk, but the appliance function
can fail. Vacuum the intake grille regularly
from outside when dust is visible, for example
as a part of the cleaning routine.
All units:
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.
