CAUTION: ELECTRIC SHOCK HAZARD Disconnect power
whenever servicing unit. More than one disconnect may be
required to de-energize unit.
Keep your air curtain operating at peak efficiency by cleaning
the blower wheels, motor(s) and intake grill. Buildup of dust on
the blower wheels can cause vibration, noise and excessive wear
on the motor bearings. The frequency of cleaning will depend
on the environment where the unit is operating.
Dirty, dusty or greasy environments could require a cleaning
schedule of once every two months. If the environment is not
that dirty, the unit(s) should be scheduled for cleaning a mini-
mum of once every (6) months.
A. PERFORMING PREVENTIVE MAINTENANCE

VIII. MAINTENANCE & CLEANING
Any service performed on the
ARCHITECTURAL HIGH
PERFORMANCE 10
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.
