CAUTION: ELECTRIC SHOCK HAZARD Disconnect power
whenever servicing unit. More than one disconnect may be
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
depend on the environment where the unit is operating.
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.

Any service performed on the
ARCHITECTURAL ELITE
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.
