Internal Mount Detailed Instructions

The following are detailed steps describing the installation of an internally mounted mast. The
exact installation procedures may vary based on the configuration of the mast system being used
and the installation environment.
5.7.2.1

Select a Suitable Mounting Location

To select a suitable mounting location, consider the following:
• The mounting area must have sufficient room to mount the mast system. The roof area must
be as flat as possible at the location of the mast. The roofline must lie between the drain hole
and RLS Guard. Mounting hardware must be at least 1 inch (25 mm) above the drain hole,
and at least 3 inches (76 mm) below the RLS Guard. The exact dimensions of the mast
system will vary based on the components included. Refer to Section 5.6 for dimension
information.
• The mounting structure must be level in all directions, solid, and capable of holding the forces
required by the bolts. Check the strength and rigidity of the mounting structure (e.g. vehicle
body) where the mast system is to be attached. Reinforce as necessary.
• The area underneath the mast must be free of obstructions to allow for accessibility to base
plate fasteners, and if present and used, the bottom air inlet port.
• The mounting location must have sufficient access for the pneumatic system.
• Before cutting the hole in the roof, it is advised to hang a plumb-bob from the roof to find the
base plate location and ensure proper alignment between the roof hole and intended base
plate location. This is particularly helpful when attempting to hit specific structural members
beneath a vehicle.
• For mounting applications using a rotatable base plate, ensure the location of the mast allows
enough clearance to accommodate the turning handles and the air hose if the air is routed to
a side air inlet port. Rotatable Super Heavy Duty masts do not use turning handles but will
need clearance for a customer-supplied rod to be inserted into the tube head to turn the
mast.
• As mast tubes extend, they force water out of the weep holes. Keep any personnel or
sensitive equipment away from the weep hole direction.
