OPTIONS AND ACCESSORIES (cont)
LIQUID PROPANE (LP) CONVERSION KITS
DURABLADE ECONOMIZER
(SIZES 036-150)
Exclusive Durablade economizer damper design saves energy while
providing economical and reliable cooling. A sliding plate on the face
of the economizer controls the amount of outdoor air entering the
system. Closed, it provides a leakproof seal which prevents ambient
air from seeping in or conditioned air from seeping out. It can be ad-
justed easily for 100% outdoor air or any proportions of mixed air.
Like the base unit, the economizer is converted easily for horizontal
discharge applications.
Designed specifically for use with Bryant commercial sys-
tems, this Bryant programmable thermostat features LED
occupied/unoccupied displays and setback mode which can
override continuous fan operation.
