BRYANT MEANS TOP QUALITY AND RELIABILITY — Each
component utilized in these units is designed and tested for a
minimum of 15 years operation under the harshest conditions.
Every unit is thoroughly run tested at the factory in each oper-
ating mode and evacuated prior to final charging. Every coil is
leak-tested with helium particles. Automated run testing allows
accurate impartial tests and measurements which are second
to none in the industry.

Each unit contains a factory printout indicating tested
pressures, amperages, dates, and inspectors, providing certifi-
cation of the unit’s status at the time of manufacture.
Units are equipped with valuable safety controls designed to
monitor and protect the unit for life. The standard safeties
include:
• low-pressure/loss-of-charge switch
• high-pressure switch
• freeze-protection thermostat
• internal compressor overload
• exclusive Cycle-LOC™ circuit board that provides compres-
pressures, amperages, dates, and inspectors, providing certifi-
cation of the unit’s status at the time of manufacture.

The cabinet is constructed of galvanized steel, bonderized and
coated with a prepainted baked enamel finish. The paint finish
is a non-chalking type, and is capable of exceeding Federal
Test Method Standard No. 141 (Method 6061) 500-Hour Salt
Spray Test. In addition, all internal cabinet panel surfaces are
primed, allowing the entire unit to have a longer life and more
attractive appearance.

EASY MAINTENANCE AND INSTALLATION
All Units are Factory Shipped in the Vertical Discharge
Configuration for fit-up to standard roof curbs. (One acces-
sory curb fits sizes 036-072; accessory curbs fit sizes 090-150
and 155-300.) The contractor can order and install the roof
curbs early in the construction stage, before decisions on size
requirements have been made.
