Electric heaters provide additional 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 includes 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 (Standard on 50JZ
042-060).
Low-ambient kit (Motormaster II control) allows
the use of mechanical cooling down to outdoor
temperatures as low as 0°F.
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.
