required to de-energize unit.

Stainless steel appliance wipes are recommended for

wiping down both the bottom panel and the cabinet.

Keep your air curtain operating at peak efficiency by cleaning

the blower wheels, motor(s) and intake screen. Buildup of dust

on the blower wheels can cause vibration, noise and excessive

wear on the motor bearings. The frequency of cleaning will

Dirty, dusty or greasy environments could require a cleaning

schedule of once every month. If the environment is not that

dirty, the unit(s) should be scheduled for cleaning a minimum

of once every six months. The air inlet filter typically requires

cleaning every three to six months.

A. PERFORMING PREVENTIVE MAINTENANCE

1. Disconnect the power to the unit.

2. Filter - the aluminum washable filter is held in by

the intake screen. Access the filter by removing the

Phillips head flush mount screws across the top front

of the unit. Rotate the inlet screen forward slightly to

allow its tabs to be removed from the bottom front

cover. Vacuum and/or wash with dish soap and water.

3. Internal - open the bottom access panel by removing

the inlet screen as described above, and then

removing the now exposed fasteners across

the front of the BAC, and the two screws along

the bottom left and right side. The BAC is hinged,

so carefully allow it to swing down.Vacuum and scrape

(if necessary) to remove the build-up of dirt

and debris. The motor(s) are permanently lubricated

and require no additional lubrication.

Any service performed on the ARCHITECTURAL Icon Series air

curtain MUST be done by qualified personnel. Berner air curtains

require very little servicing. All parts are easily accessible for

periodic inspection and maintenance. Units should be cleaned

at least twice a year. Your particular application (the amount of

dirt and dust in the air) and location of the unit(s) will determine

how often your unit(s) will need to be cleaned and serviced. All

motors have permanently lubricated, sealed, sleeve bearings

and require no maintenance.
