READ INSTRUCTION BEFORE REMOVING FROM CARTON
INSTALLATION INSTRUCTIONS: PRELIMINARY
1. Carefully remove the unit from the box. Loosen the
    screws from the intake screen and remove the intake
    screen.
1. Center the air curtain mounting bracket on solid wall
    over doorway.
2. Spot holes through 5/16" mounting holes in bracket.
    If necessary, drill additional holes in bracket to match
    wall stud or any other mounting bars spacing supplied
    in the field.
2. Gently remove all packaging materials, hardware and
    other accessories from interior of unit prior to operating.
3. Remove the Tek Screws from the wall mounting plate
    and remove the mounting plate from the unit.
3. Securely fasten mounting bracket with the proper
    fastener and set air curtain in key hole slots provided.
4. Install the mounting plate above the opening. The
    lowest point of the unit must be at least 1" above any
    obstructions, ie.. doors and/or door closers, etc...
    when the unit is installed.
4. Adjust air directional vanes approximately 15°
    towards the wind load.
5. Connect to proper voltage and phase.
5. Align the tabs on the rear of the unit with the slots
    provided on the wall mounting plate (see drawing
    below). The bottom flange on the unit must also drop
    in the bottom channel of the wall mounting plate.
   Replace the Tek Screws to secure the unit in plate.
NOTE: LoPro air curtains are not recommended for
heavy insect control.
ADJUSTMENTS
1. Pull air directional vanes in air discharge nozzle to
    proper position with air flow slanted slightly outward
    around 15°.
NOTE: If the holes provided on the bottom of the unit
and the bottom of the wall mounting plate do not align,
remove the unit and re-install The holes on the bottom
channel of the wall mounted plate must be on the bottom.
2. Set air velocity control louvers so that the air stream
    just reaches the floor to prevent turbulent mixing of
    inside and outside air.
6. The discharge must be free and clear of any
    obstacles for optimum performance.
3. The unit is to be installed such that the airflow is
    unobstructed.
7. All wires must be connected internal of the unit and
    some knockouts are provided. However, it may be
    necessary to create your own knockout, as required.

MAINTENANCE INSTRUCTION
ROUTINE MAINTENANCE WARMING - TO REDUCE THE RISK OF FIRE,
ELECTRICAL SHOCK OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
It is imperative to keep the fans clean, as they eventually
become coated with residue. Dirty fans will lower the
efficiency and eventually throw fans out of balance which
can shorten the life of the blower wheels and cause undue
wear on the bearings. The time between cleanings depend
upon the type and amount of particles floating in the air.
Under normal circumstances, the system will require
cleaning only about once a year.
Use this unit only in the manner intended by the
manufacturer, if you have any questions, contact the
manufacturer. Before servicing or cleaning the unit,
switch power off at service panel and lock to prevent
power from being switched on accidentally. Servicing
an energized air curtain presents a risk of fire, electric
shock or injury to persons. DO NOT attempt any
maintenance unless the electric supply has been
completely disconnected. Installation work with all
electrical wiring must be done by qualified person(s) in
accordance with all applicable codes and standards.
When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
TO KEEP THE LoPro AIR CURTAIN LOOKING
NEW, REMOVE SCREWS FROM AIR INTAKE
OPENING AND REMOVE AIR INTAKE GRILLE.
CLEAN ACCUMULATION OF DIRT FROM
MOTOR HOUSING, BLOWER WHEELS &
INTAKE GRILLE THEN REINSTALL INTAKE
GRILLE.
