1.3.6 Main Circuit Breaker

An additional main circuit breaker can be
field installed between the power source
and the Circuit Panel. This circuit breaker
can be mounted on the exterior of the main
housing unit or in a remote location to allow
power to be disconnected prior to opening
the RRSHA Hot Air Blower for service.
NOTE:
For information on purchasing an
additional main circuit breaker for
field installation contact Spectrum.

Accessories

Accessory equipment can be included to place
the main housing unit of the RRSHA Hot Air
Blower in the optimal location relative to the
switch area, to allow greater access or to
provide a visual verification of system
function.
1.4.1

Height Adjustment Legs

Height Adjustment Legs are
recommended in areas where standing
water can pool or accumulate.
Legs also allow for stable and level footing on
an otherwise uneven ground. The main
housing unit can be raised to a maximum of
18" with the height adjustment legs.
The RRSHA Hot Air Blower is provided from
the factory with Height Adjustment Legs
when Suffix "M" is identified in the model
code during the initial specification process

1.4.2 Duct Extensions

The stainless-steel duct connecting the main
housing unit to the track duct is flexible and
extends up to 66". If the main housing unit
must be installed at a greater distance or
elevation from the track rails, flexible duct
extensions made of stainless steel and high-
temperature silicone packing are available.

1.4.3 Ground Fault and Power-
On Indication Lights
Indication Light
The RRSHA Hot Air Blower can be
provided from the factory with
indication lights. When Suffix "P1" is
identified in the model code during the
initial specification process the
indication light is mounted outside the
main housing unit and configured to
provide a visual signal when a circuit
breaker trips or when a ground fault
occurs on the rod/crib circuit.
Alternatively, when Suffix "P2" is
identified in the model code, the
indication light can be configured to
illuminate when the RRSHA Hot Air
Blower is powered. If desired, two
separate indication lights can be
installed, one for ground faults and the
other for power. The default light color
is white, with additional colors available
on request.
