Description
This gasket is used to provide a good air
seal between the top of the hood and the
diffuser.
The hood captures the air and directs it
toward the manifold.
Intended for use when the Balometer Jr. is
used in conjunction with a ladder. Allows
for easy one-hand support of unit.
Intended for use when the Balometer Jr. is
used without the aid of a ladder. Extended
reach allows easy access to many ceiling
diffusers while standing on floor.
The meter is calibrated to provide flow
readings in either cubic feet per minute or
cubic meters per hour. Separate scales
corresponding to the position of the range
selector are provided.
Rotating this screw allows the meter to be
set at zero. This adjustment should only be
made with the range selector set to OFF and
with no airflow past the manifold.
The 7-position switch is used to select the
required flow range and operating mode
(supply or return). The OFF position
prevents flow from passing through the
meter.
Covers range selector and meter system.
