GA Series Commercial Air Curtain, User and Installation Manual

WORKING PRINCIPLE

Air curtains are designed to keep the air in the room separate from the outside air, thus preventing the heated or cooled indoor air from leaking outside and pests and obnoxious smells from entering inside. It creates an invisible air screen at the openings to the outside.

The unit should be installed above the opening to cover the entire width of an external door. Suggested height is between 8 to 10 feet from the floor level.

The air inside the room is sucked in by two centrifugal fans through the decorative front grilles and then directed through manually adjustable louvers downwards, all the way to the floor. Motor provides high and low speed settings which can be selected by the user.

CHOICE OF MODEL

The air curtain should have the same length as the width of the door, over which it will be installed. If necessary, two or more curtains can be installed side by side, to attain uniform coverage across the entire opening.

To obtain maximum performance, the air outlet should be positioned in immediate correspondence with the top edge of the door and the air flow speed at ground level must be between 300 and 500 foot/min.

GA series air curtains are equipped with 6 inch diameter centrifugal blowers and provide excellent coverage when installed at heights up to 12 feet max.

(preferably between 8 and 10 feet) from the floor.

INSTALLATION

Installation location

The installation location of the air curtain must be indoors only, on a solid and vibration free wall. Do not install the appliance in an excessively humid location or in a place where it can be easily sprayed with water. If possible avoid installing the unit where there is direct sunlight.

If the door is wider than the air curtain, two or more units can be installed side by side.

Installation of the Mounting Frame:

1) After removing the appliance from the packing, separate the mounting frame from the air curtain (attached to the back of the unit at the factory as packed);

2) If included, remove the styrene protective inserts, placed inside the unit to prevent the blower wheels from damage during the shipment (see separate instructions).

3) Position the mounting frame so it is perfectly level and mark the fastening holes (see the drawings provided for details);

4) Fasten the mounting frame to the wall using screw anchors which are suitable for the type of wall;

5) Hook the air curtain on to the mounting frame and fix it using the provided screws at the bottom part.

There should be no space left between the curtain and the wall once installation is complete.

Installing on the wooden wall:

Fix the mounting frame with the proper wood screws on the chosen position.

Start up

Once installation is complete, connect the power supply cable to the 110~120V receptacle. This air curtain is equipped with a three-lead electric cable (line, neutral, Ground), which should be connected to properly grounded and receptacle with proper protection.

LOUVER ADJUSTMENT

The adjustable louvers allow the air flow to be directed as required.

Usually the louvers are to be pointed vertically, to direct the air flow vertically towards the floor.

If the air curtain is installed in a windy area the louver can be pointed slightly towards the outside, in order to balance the wind force.
