Perpendicular Installation Example
3. For the safety of the internal
components and personnel, the
RRSHA Hot Air Blower must be
grounded to earth. Install a ground
rod and connect it to one of the
grounding lugs inside the control box.
2.1.2 Routing power to the main
housing unit
The power supply was determined before the
RRSHA Hot Air Blower was ordered and is
included within the Model numbering. The
power supply must deliver the required
voltage and load carrying capacity.
1. Make sure the power supply cable is
sized properly for the RRSHA Hot Air
Blower, and that the electrical service
allows the unit to operate properly.
Low voltage reduces the unit's
effectiveness and shorten its life
span.
2. Drill holes into the bottom plate of
the main housing unit and into the
circuit panel for the main
power cable and for cables of any
optional equipment.
3. Route the cables through the holes.
Ensure each hole is completely sealed
with a water-tight solution.
NOTE:
Do not connect the cable
from the power source to
the Circuit Panel at this
time.

2.1.3 Installing the track duct

The track duct is comprised of two sections.
The Outboard Track Duct has one closed end
and one open end. The Inboard Track Duct
has two open ends. These two sections are
connected and tested for electrical isolation
prior to shipment.

Track Duct
Install the track duct one or two tie spaces in
front of the switch point, with the nozzle ends
five to ten inches from the tip of the switch
point.
1. Clear the installation area of ballast to
allow the track duct to slide in
position under the rail.
2. Pass both sections of the track duct
under the stock rail.
3. Position the Outboard Track Duct so
that it is approximately 6" from the
outside rail and centered between
the two existing ties.
