General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The product may only be used as set out in
the assembly and operating instructions. The
guarantee is only valid if the product is used
in the manner intended and in accordance
with the instructions.
Application area
UF600 creates a very effective air barrier
when air at high speed is pushed out through
a narrow channel situated in the floor inside
the door opening. An air barrier directed
upwards from the floor gives the best possible
protection against cold air flowing into the
premises.
UF600 consists of one or two pillars with
inlet hood, silencers and fans, as well as a
floor channel with its slot at floor level. The
pillars are placed inside or outside the door
on either (or both) sides of the opening. The
floor channel width and blowing angle is
adapted to the specific door.
Ambient Temperature limits: -20 °C –55
°CProtection class: IPX4.
Operation
The air is drawn in through the air inlet at
the top of the unit and blown out through
a narrow air outlet slot in the floor. The air
is distributed at high velocity across the
doorway, providing a protective air shield.
The air shield minimises cold draughts and
reduces heat loss through open doorways.
The air outlet slot is angled outwards
15° to achieve the best protection. The
efficiency of the air curtain depends on
the air temperature, pressure differences
across the doorway and any wind pressure.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced!
Assembly and operating instructions
Mounting
The AF600 unit is assembled according to
this manual and bolted together with supplied
bolt kit. The floor duct design choosen is cast
into the floor complete with air outlet slot,
inspection hatch and connection box. The air
outlet slot should extend approximately 100
mm outside the door edges.
The UF600 unit is connected to the
connection box with the flange shown in this
manual, see fig. 3.
For indoor mounting the air intake should
be above the door opening, therefore an
extension of the column is sometimes
necessary. Column extension can be ordered
by length from Frico.
The UF600 unit should be fastened in ceiling
or wall to avoid the risk of tipping if the unit
is hit by a vehicle.
If the air outlet slot is more than 150 mm
away from the door opening internal door
protectors should be mounted on both sides
of the door to increase air curtain effect.
Standard max load on air duct is 7 ton, up to
20 ton for special orders.
Electrical installation
The air-curtain should only be wired by a
competent electrician, and in accordance
with the latest edition of IEE wiring
regulations. The connection is via the
terminal box fitted on the outside of the fan
housing.
Service, repairs and maintenance
Periodically check the following according to
official requirements, however at least once
a year (the first four points only with the fan
switched off!):
• Screw connections, specifically the rotor
fitting.
• Is there dirt in the fan wheel? If so, remove
it.
• Have accumulations formed the rotor? If so,
remove them.
• Function of the safety components.
• Coil resistance
• Function of the control elements.
• Operating current.
