Application
3200 series is a compact air curtain with a
recommended installation height of up to 11 feet.
The air curtain has an integrated control system
and can be remotely controlled.
The air curtain is available without heat, with
electrical heating and with water heating.
Protection class for units with electrical heating:
IP20.
Protection class for units without heating and units
with water heating: IP21.

Operation

Air is drawn in at the top of the unit and blown
downwards shielding the door opening and
minimizing heat loss. To achieve the optimum
curtain effect the unit must extend the full width of
the door opening.
The grille for directing the outlet air is adjustable
and is normally angled outwards to achieve the
best protection against incoming air.
The efficiency of the air curtain depends on the
air temperature, the pressure differencial across
the doorway and any wind load.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced.
Mounting
The air curtain unit is installed horizontally with the
supply air grille facing downwards as close to the
door as possible. Minimum distance from outlet
to floor for electrically heated units is 70.9 in. For
other minimum distances, see fig. 4.
Brackets and torx bit are enclosed in the gable
end packaging upon delivery.

Horizontal mounting on the ceiling
Threaded rods, hanging brackets and ceiling
mounting brackets for ceiling mounting are

and separate manuals.
Electrical installation
The installation, which should be preceded by
an isolator switch with a contact separation of at
least 0.12 in, should only be wired by a licensed
electrician and in accordance with the NEC and
the local electrical codes and regulations. The
control system is pre-installed in the air curtain.
Unit without heating or with water heating
Connected via the built-in control board with
4.9 ft cord.
Unit with electrical heating
The electrical connection is made on the top
of the unit. See Fig.2. 208V3~/480V3~/600V3~
power supply for heat and control (*1 *2) should
be connected to a terminal block in the primary
terminal box.
• 1* 480V3~/ 600V3~ Control supply is
transformed via internal transformer to 230V~
and routed through 2x 10A fuses in the primary
terminal box.
• 2* 208V3~ Control supply is connected
internally through 2x 10A fuses in the primary
terminal box.
