Installation and operating instructions
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
PA1508-NA is primarily intended for small
openings such as kiosk and service hatches
and cashier benches where a long, narrow air
flow is required. This creates a temperature
separating air barrier that prevents cold air
from pushing in and hot air from flowing
out. PA1508-NA also gives additional heat
and in this way also improves the working
environment.
Protection class: IP20.
Operation
Air is drawn in at the top of the unit and
blown out downwards so that it shields the
opening and minimizes heat loss. To achieve
the optimum curtain effect the unit must
extend the full width of the opening.
The efficiency of the air curtain depends
on the air temperature, pressure differences
across the opening and any wind pressure.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced.
Mounting
The air curtain is installed horizontally with
the supply air grille facing downwards as close
to the opening as possible. Minimum distance
from outlet to floor is 1800 mm/70.9 in. For
other minimum distances, see fig. 3. Bracket
is supplied for wall or ceiling mounting. The
unit can be tilted for optimum output.
1. Fit the bracket on the wall or on the ceiling.
2. Guide the unit onto the bracket through the
opening at the rear or on top.
3. The unit is secured by guiding the slot in the
bracket over the screw (PH2) inside the unit
Control
The air curtain has a built-in thermostat for
heat and switch to set the fan and heating
steps.

Electrical installation
The installation, which should be preceded
by an omnipolar/cut-off switch with a contact
separation of at least 3 mm/0.12 in, should
only be wired by a competent electrician and
in accordance with the latest edition of IEE
wiring regulations.
The PA1508E-NA must be permanently
connected to a fused mains supply using a
cable of a minimum 4 mm

and then tightening the screw from outside
of the unit.
See Fig. 1-3.
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.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. Loosen the screws on the intake grille and
remove grille.
3. Lift the front.
See Fig.2.
