absorb vibration and allow for a complete sealing of the
machine to the mounting surface. For ordering details,
consult
Appendix A, Section A.5
(#20).
4.6 GROUNDING THE MACHINE
The machine frame must be grounded to the truck
chassis using a minimum 2 gauge wire. Connect the
ground cable to the unit battery.
4.7 INSTALLING THE CONTROL
TRUNK LINE
If the machine location calls for an access hole to be
drilled in the vehicle body, the hole size must
accommodate the 1/2” air line. When drilling the access
hole, ensure that there is no hindrance to any access, or
operation of, other standard or mounted vehicle
system(s), including any under deck or accessible wiring,
piping, etc.
Once the access hole is drilled, place a rubber or suitaby-
protective grommet around the circumference of the hole
to protect the air line from being cut or worn.
1. Route the control trunk-line through the
grommetted opening.
2. Connect the 1/2” air line via the JIC fitting on
the end of the air tank, and connect and
secure the weatherproof connectors. The
plugs are all differentiated to ensure that they
cannot be mis-connected.
4.8 INSTALLING THE (OPTIONAL)
REMOTE CONTROL PANEL
Install the (optional) remote control panel at the desired
location on the service body and route the control trunk
line to the location where the unit will mount. Ensure that
all sharp edges that the trunk-line contacts are shielded
or grommetted, and that there are no excessively sharp
bends in the trunk-line. Ensure the trunk line does not
come in contact with exhaust parts.
4.9 INSTALLING THE REMOTE AIR
TANK
The air tank, and subsequent piping, must have a
minimum rating of
200 psi
; if tank is larger than six
inches (6”) OD, it must be ASME rated. To determine the

Nylock nuts should be used to prevent the
mounting hardware from loosening, due to
vibration from travelling, operating, etc.
II
A minimum of four (4) vibration isolators are
required (Vanair no. PR271935).
Some or all of the mounting hardware used
to mount the machine to the shipping crate
may be reused when mounting the machine
to the vehicle. However, depending upon
the thickness of the vehicle mounting
surface, or if using vibration isolators, the
mounting bolts or vibration studs may not
be long enough to secure a proper
fastening. Be aware that a minimum thread
clearance of 2-1/2” threads showing above
the nut, with the machine fastened in place,
is required (see
Figure 4-3
).
