4. To operate using the Berner Air Curtain App
NOTE: The air curtain must have been ordered
from the factory with the wi-fi controller to use this
option. The wi-fi controller allows air curtain(s) to be
programmed & operated via smart phone.
Requires on-site, secure wi-fi connection (provided by
others).
Download the "Berner APP" to your smart phone from
the Google Play store. Follow the prompts. Berner
recommends having the on-site user(s) set-up the Berner
App on his/her smart phone.
B. AIR STREAM ADJUSTMENT
1. With the air curtain operating and the door in its full
open position, check to see that nothing is obstructing
the airflow at the discharge nozzle vanes.
2. Find the air stream split location. Hold a handkerchief
by its corners, approximately 12" above the floor. Gently
move the handkerchief back and forth in the doorway.
Make sure the air is being directed to both the inside and
the outside. See Figure 10. The split location is indicated
where the handkerchief is vertical with minimal or no
fluttering.
3. The split location should be approximately 3" outside the
doorway. If necessary adjust the discharge nozzle vanes
by de-energizing the unit, loosening the nozzle vane
locking screws and adjusting vanes.
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 efficiency 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. If the environment is
not that dirty, the unit(s) should be scheduled for cleaning a
minimum of once every (6) months. To access the interior of
the unit:
A. PERFORMING PREVENTIVE MAINTENANCE
1. Disconnect the power to the unit.
2. Remove the discharge grille by unscrewing the six (6)
Phillips head screws located on the inside edge of the
grille. See Figure 9.
3. Remove the intake grille by lifting up on both sides with
equal force. Once the grille is detached, pull the grille
away from the unit until it clears the shoulder bolts. This
will expose the bottom access cover mounting bolts and
the heating coils (if applicable).
