INVISIDOR STYLE AIR CURTAIN: Installation, Operation & Maintenance Instructions

Vertical Style Air Curtain
2
The air curtain must be surface mounted within the building and not exposed to the external
environment or moist conditions. Do not install the air curtain in a doorway situation where there is a
likelihood, or there has been a history of, rain ingress. The air curtain must not be built into a
compartment or recessed.
Location
Prior to commencing any vertical installation it is essential to ensure the correct handing has been
selected, i.e. Left Hand (LH) or Right Hand (RH) - . see "Handing Guide" in Figure 6. Maximum doorway
width = 2.5m per air curtain.
For maximum effectiveness, it is essential to ensure the height of the air curtain is slightly higher than
the opening height of the door. Obstructions such as door opening devices, structural beams etc will
reduce the efficiency of the air curtain. There must be at least 200mm clearance at the air inlet for air
to enter the unit, see Figure 6.
Floor Fixing
Using the 2.5mm hexagon key wrench supplied, unfasten and remove all the casing screws from the
air curtain and carefully detach both sections of casing. All screws should be kept safe as they will be
required later in the installation.
Before installing the Style air curtain obtain four suitable fixing bolts, taking into account floor type and

unit weight (see Table 1)*. Rawlplug M10 Projecting Rawlbolt 44356 type may be suitable. For

favourable position. A wall bracket must be fitted to the top of the unit for Style 250V and Style 300V

stacked air curtains to tether the top of the unit to the wall. In order to use the wall bracket supplied
ensure the back of the foot plate is no more than 25mm away from the wall. If skirting board, with
maximum depth of 25mm is fitted, ensure the back of the foot plate is touching the skirting board.
Using the foot plate as a template, mark the location of the four holes, as indicated in the adjacent
picture. Using a suitable masonry drill bit, correctly drill the four marked out holes. Place M10 fixing
bolts into each hole, ensuring all bolts are upright.
Reposition the air curtain foot plate over the projecting bolts. Tighten each M10 nut as indicated in the
adjacent picture. Ensure the vertical unit is secure, upright and square.
It is the sole responsibility of the installer to ensure that the floor and any fixing points are
suitable for the air curtain being installed.
