VIII. MAINTENANCE & CLEANING

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 eciency by cleaning

the blower wheels, motor(s) and intake grille. 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. Otherwise, the unit(s)

should be scheduled for cleaning a minimum of once every (6)

months. To access the interior of the unit:

A. Disconnect and lockout power to the unit. If necessary

remove the blower assembly. See Section VIII SERVICE for

instructions on how to remove blower module.

B. Remove the bottom access cover by removing (2) Phillips

head machine screws located at the cover’s corners.

See Figure 7.

C. Vacuum and scrape (if necessary) to remove the buildup

of dirt and debris from the interior of the air curtain. The

motor(s) are permanently lubricated and require no ad-

ditional lubrication.

D. Pull the lter out from underneath the struts of the bottom

access cover. It is easiest to work from the middle, pull-

ing one side out and then the other. Spray the lter with

warm, soapy water, rinse, and pat dry.

E. Replace Filter.

F. Reinstall the bottom access cover.

G. Switch the power on after cleaning.

CAUTION: STAND CLEAR of the unit or wear safety goggles

as loose debris may be present and may exit the nozzle.
