ISOLAIR MANUAL INTRODUCTION
Warning:
w Applications other than those described
above are deemed to be ‘usage other than for
the intended purpose’. Biddle is not liable for
damage or loss resulting from usage other
than for the intended purpose. Usage for the
intended purpose also entails observance of
the instructions in this manual.
1.3.2 Operation
The air curtain blows out a stream of air straight downwards
and thereby achieves the following:
• The exchange of air between two rooms due to a temperature difference (convection) is stopped.
en
Depending on the setting of the air curtain, the unit can also
blow out unheated air.
1.3.3 Type designation
The table below provides an overview of the available models
of the cold room air curtain and the corresponding type designations. In combination, the type designations constitute the
type code, for instance: IsolAir150.
If some part of the manual applies to certain models only,
these will be indicated with the corresponding type designation, for example:

2.4 Hanging the unit up
2.4.1 Suspension method
Example of an auxiliary structure This manual assumes suspension from an auxiliary structure,
consisting of two horizontal beams positioned above the door.
You may also fix the units directly to the ceiling, or to another
horizontal structure, using the screw holes in the upper side
of the unit.
w Make sure that the structure from which the
unit is about to be suspended can bear at
least 4 times the weight of the unit.

1.3.4 "Type plate" on page 6
2.4.2 Determine the location of the unit
• The unit should preferably be placed in the room where
the temperature is highest.
• Position the underside of the unit at the same height as the
top of the doorway.
• Position the discharge side of the unit as close to the doorway as possible, to ensure optimum operation.
n If the distance is greater than 5 cm., you are advised
to seal off the openings at the side. For this purpose,
you can order a side shield of plastic strips from
Biddle.
• Position the row of units centrally in relation to the doorway.
• Units of different widths can be positioned in random
order.
• Make sure that the inspection and intake sides of the units
remain accessible for maintenance.
w Make sure that all units can freely take in and
blow out air across their entire width.
