FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Manual OA Damper
Manual outdoor air dampers are an economical way to
bring in ventilation air. The dampers are available in 25%
and 50% versions.
Motormaster Head Pressure Controller
The Motormaster motor controller is a low ambient, head
pressure controller kit that is designed to maintain the
unit’s condenser head pressure during periods of low
ambient cooling operation. This device should be used as
an alternative to economizer free cooling not when
economizer usage is either not appropriate or desired. The
Motormaster will either cycle the outdoor fan motors or
operate them at reduced speed to maintain the unit
operation, depending on the model.
Alternate Motors and Drives
Some applications need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, your Carrier expert has a factory installed
combination to meet your application. A wide selection of
motors and pulleys (drives) are available, factory
installed, to handle nearly any application.
Thru--the--Base Connections
Thru--the--base connections, available as either an
accessory or as a factory option, are necessary to ensure
proper connection and seal when routing wire and piping
through the rooftop’s basepan and curb. These couplings
eliminate roof penetration and should be considered for
gas lines, main power lines, as well as control power.
Disconnect Switch Bracket
Provides a pre--engineered and sized mounting bracket for
applications requiring a unit mounted fused disconnect of
greater than 100 amps. Bracket assures that no damage
will occur to coils when mounting with screws and other
fasteners.
Supply Duct Cover
This supply duct cover is required when field converting
the factory standard vertical duct supply to horizontal duct
supply configuration. One is required per unit. (14 size
only.)
Electric Heaters
Carrier offers a full line of field--installed accessory
heaters. The heaters are very easy to use and install. All
are pre--engineered and certified.
