Basic Twister Installation and Operation
Important: Read and understand operation manual before installation
.
1. a) Trace base size and mount hole locations onto cardboard and use as template to drill holes to
mount compressor in suitable location. Use caution when drilling; check below for obstacles.
b) Allow for proper fitting, hose, wire routing. Allow for proper ventilation and service access.
2. Mount compressor to service body using 4 holes provided in base. Securely fasten. Use locking
fasteners.
3. a) Run supply and return fuel lines to truck diesel fuel tank. Use the auxiliary pick up provisions
on tank. Note: Do not cut into the truck engine lines. Consult vehicle manufacturer for
proper procedure, use kit part number ATA013.
b) Use caution to prevent rubbing/pinching on fuel line when vehicle in motion and any contact
with hot or moving parts.
c) Electric fuel pump on Twister may need to be relocated near to fuel tank on long fuel line runs
or with for high lifts (over 3 feet) and long runs (over 6 feet).
d) An electric auxiliary fuel pump is available for long fuel line runs for long fuel line runs Part
Number AOF003
4. Run battery cable from Twister to truck battery. Install a 150 amp circuit breaker (Electric tie in kit
Part Number ATA012) in system, near battery; size cable properly for length of run. Protect from
rubbing and damage.
5. Mount Twister control panel in accessible location. For extended length location use extension
P/N AOCBH10
6. If connecting truck cooling system to Twister, use Airw
orks’ Cold Weather Package, P/N
ATO112.
NOTE: Any alteration to Twister cooling system will result in a void warranty!
7.
Operating unit with low coolant level will cause damage not covered by Warranty!
8. Avoid cooling air flow restriction, air must flow freely into unit and exit from unit without restriction.
Ensure hot air is not redirected into cooling air stream.
Installation Notes
The electric fuel pump on the Twister is not capable of drawing fuel from long distances. If the installation
of the Twister is more than 6 feet from the fuel tank, the pump should be relocated closer to the fuel tank.
An auxiliary fuel pump is available from Airworks, part number ATO110 for long runs (more than 6 feet) or
high lift (more than 3 feet).
Restrictions in the air line such as 45 degree and 90 degree fittings should be limited to 3 or less. Too
many direction changes or elbows will lead to loss of air flow. Size fittings at least the same size as twister
air outlet or larger.
When installing the Twister in a confined location, direction of airflow through the unit should be
considered. A source of fresh air in and a place to vent the warm air is critical to the proper operation of
the compressor and engine. Do not allow or cause warm air to recirculate back into compressor.
When connecting the battery cables to the Twister, it is recommended to use a minimum 4 gauge welding
cable with a 150 amp breaker in line. Due to the rubber mounting bases on the Twister, it is
recommended that the unit is grounded, using supplied ground lead from Twister to chassis battery.
*for installation at a distance over 12’ from battery, heavier cable is recommended.
