General Instructions

Read these instructions carefully prior to
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 should the product be used
in the manner intended and in accordance with
the instructions.
Application
Pamir creates an efficient temperature dividing
air barrier in door openings.
Pamir 3500 has a recommended installation
height of 3,5 m.
Pamir 4200 has a recommended installation
height of 4,2 m.
Pamir 5000 has a recommended installation
height of 5,0 m.
Pamir air curtains are available in 3 versions:
without heat (ambient), with electrical heating,
or with water heating.
Protection class for units with electrical heating:
IP20.
Protection class for units without heating and
units with water heating: IP24 (IP21 when
vertically mounted to the left, seen from the
inside.)

Operation

Air is drawn in at the top/rear of the unit and
blown downwards/outwards shielding the
door opening and minimizing heat loss. To
achieve the optimum air curtain effect the unit
must extend the full height/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.

Installation and operating instructions
Mounting
The air curtain range can be adapted for
vertical or horizontal installation. The units can
also be installed by recessing into suspended
ceilings.
The product must be mounted in such a way to
allow future service and maintenance. Ensure
that the front panel/service hatch is accessible
and can be fully opened.

Horizontal mounting

The air curtain is installed horizontally with the
outlet air grille facing downwards as close to
the door as possible. Minimum distance from
outlet to floor for electrically heated units is
1800 mm. For other minimum distances, see
fig. 3.
For the protection of wider openings, several
units can be mounted next to each other using
a joining kit PA3JK/PA4JK.
The design kit which conceals cables, pipes
and mountings is available for both wall and
ceiling installations.
Mounting with wall brackets
Wall brackets PA34WB and PAWBL are available
as accessories.
1. Remove the plastic covers on the wall
brackets. (Fig. 6A)
2. Mount the brackets on the wall according to
the dimensions fig. 6B.
3. Fasten the hammerhead screws on the unit
in the holes M8. (Fig. 5 and 6C)
4. Lock the nuts so that the hammerhead
screws are at 20 mm height. Note the
direction of the screw heads. (Fig. 6C)
5. Slide the unit on the consoles. (Fig. 6D)
6. Lock the nuts against the bracket and return
the plastic covers. (Fig. 6E)
Horizontal mounting on the ceiling
Threaded rods, wire suspension kits and ceiling
brackets for ceiling mounting are available
as accessories, see fig. 7 and 8 and separate
manuals.
Horizontal recessed mounting in false ceilings
