Factory-installed options
Coil options
include copper/copper and vinyl-coated
construction for refrigerant coils. Units are shipped standard with
copper tube/aluminum fin construction. See model number
nomenclature for coil options.
Electronic Variable-Speed Motor — ICM Motors (Integrated
Control Motor) provide variable-speed operation to optimize
comfort levels year round. They are also more economical to
operate than standard motors.
Field-installed accessories
Economizer with solid-state controls and barometric relief
dampers
includes filter racks and provide outdoor air during
cooling and reduce compressor operation.
Manual outside air damper includes hood and filter rack with
adjustable damper blade for up to 25% outdoor air.
Electric heaters provide heat in the unit when required. Each
package has a heater module that slides into the controls
compartment. Heater sizes range from 5.0 to 20.0 kW. The
electric heater design allows the use of a single-point power
supply for the entire unit, resulting in lower installed costs.
Flat roof curbs in both 8 in. and 14 in. sizes are available for roof
mounted applications.
Square-to-round duct transition kit enables 024-048 size
units to be fitted to 14 in. round ductwork.
Thermostats provide control for the system heating and cooling
functions. Thermostat models are available in both programmable
and non-programmable versions.
Lifting kit, including 4 metal brackets that fit into the hand-holds,
a support strap and two safety straps, is available to assist in
lifting this product onto a roof application.
Crankcase heater provides anti-floodback protection for low-
load cooling applications.
Low-ambient kit (Motormaster II control) allows the use of
mechanical cooling down to outdoor temperatures as low as 0°F.
Solid-state Time Guard II device provides short-cycling
protection for the compressor. Not required with corporate
electronic thermostats.
Filter rack features easy installation, serviceability, and high-
filtering performance for vertical applications.
Compressor hard start kit assists compressor start-up by
providing additional starting torque on single phase units and
prolongs compressor motor life.
