whenever servicing unit. More than one disconnect may
be required to de-energize unit.
Any service performed on the ARCHITECTURAL ELITE 8

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.
