HEAVY DUTY/VEHICLE BRACKET
BRACKET INSTALLATION AND MOUNTING
Make certain that the mounting location and position meet
NFPA 10 requirements and ANSUL limitation requirements.
The brackets are provided with four mounting holes in the
back plate (frame) and four mounting holes in the base. The
mounting surface will usually dictate that either the back or the
base holes be used, but in some instances both sets may be
used to improve the stress distribution. Use good quality 3/8
inch fasteners, one in each mounting hole. Fasteners should
be tightened as is recommended for the specific type and
grade of fastener being used.
Even though welding is an effective method of securing the
bracket in place, it is NOT recommended. This is because
ANSUL has no control over the placement and quality of the
welds.
After the bracket is properly installed, refer to the Adjustment
Section. Proper adjustment is vital if the extinguisher is to be
held firmly and not damaged.
MOUNTING LOCATION
Two basic areas of consideration will affect the choice of
bracket mounting location.
The first considerations are fire protection needs.
1. The extinguisher must be visible, not hidden in an out-of-
the-way spot.
2. The extinguisher must be easily reached, even from the
ground.
3. It should not be placed where a vehicle fire is likely to
make it inaccessible.
The second set of considerations deal with keeping the extin-
guisher safe and secure.
1. Choose a place that is relatively safe from falling rocks
and tools, and where the brushing of tree limbs, or minor
collisions are not likely to cause damage. Often the best
place is at the rear, a few feet from the ground.
2. Avoid locations where grease or oil could build up on the
extinguisher and bracket.
3. Select a mounting surface which is strong enough to
support the weight of the extinguisher and bracket during
vehicle operation, and is relatively flat to avoid stress on
the bracket.
4. Avoid surfaces which may flex enough to cause metal
fatigue in the member supporting the bracket.
5. Be sure there is enough space to allow proper mounting
of the bracket and easy access to the extinguisher.
6. Avoid locations that may expose the extinguisher to
temperatures which are detrimental to its operation such
as too near a motor or manifold.
