air stream and affect the location of the unit.
For the air curtain to work well the width of the open doorway
should be less than the length ‘A’ of the air curtain, see the
‘Mechanical Drawing’section. Where the door way is wider
multiple units should be placed side by side with a 1 inch gap
as show in Fig 2.

Overheat Safety cut-out
The air curtain is equipped with a thermal protective device that will trip if the unit over heats, causing
the fan to stop turning. Should this activate, unplug the device and allow it to cool down for a minimum
of 3 hours.
Investigate the cause of the overheating and reconnect the device when the cause has been fixed.
If the thermal protective device keeps overheating then contact Thermoscreens or an authorised
reseller.
Every week
Turn off the air curtain to prevent entry of dust then clean the face of the air inlet grilles using a
vacuum cleaner with an extension tube and brush.
Every 6 months
Clean and inspect the inside of the air curtain as follows:
Step 1 Unscrew the device from the mounting bracket above the door way.
Step 2 Open the casing to gain access to the internals.
Step 3 Clean and remove any build-up of dust and dirt within the air-curtain (inlet/outlet grilles, fan
impellers, housings and motors) using a vacuum cleaner and soft brush.
FAULT CONDITIONS
