TRANSPORTING YOUR QTAC
Gross Vehicle Weight Rating
•Ensure that the gross vehicle weight rating (GVWR) of the QTAC carrying vehicle is
sufficient to support your QTAC unit with a full tank of water, plus any equipment,
fluids and personnel that you may wish to carry. Alternatively, you can reduce the
volume of water in your QTAC to maintain a GVWR under the limit of your vehicle.
General QTAC Mounting and Fastening
Figure 4 – Mounting Options
Ensure that your QTAC unit is secured to the carrying vehicle. Two main mounting
methods are available for your QTAC unit:
1. The preferred method of securing the QTAC to the bed of the vehicle is to mount
the QTAC at the forklift runner slots (Figure 4) located at the bottom of the water
tank on each side. The flanges have been machined to accept a variety of
mounting hardware options. Mounting hole locations are 43 7/8” across x 31 front
to rear.

2. If using straps to secure the QTAC to the bed of the vehicle, feeding the strap
around two grab rail posts, is preferred. This distributes the downward force over
a greater area. (Figure 4)
Securing the strap around a single grab rail post is acceptable. (Figure 4)
Securing the strap around the upper grab handle is not an approved method to
secure the QTAC (Figure 4). This will result in warping of the plastic handle, and
will eventually lead to handle failure.
For both mounting methods, ensure that the bottom of the QTAC (including the
mounting flanges) abuts a firm, flat surface or rack. Avoid significant leveraging of the
mounting flanges.
Special Precautions for Carrying a QTAC on Ride-On ATVs or Side-By-Side
UTVs
• Ensure that the area to which you are securing your QTAC is an approved
loading area for your ATV or UTV.
• Ensure that the weight of your QTAC does not exceed the maximum
recommended weight of the ATV or UTV loading area to which you are securing
your QTAC.
• Loading the bed of your ATV or UTV may affect steering response. Therefore,
the operator should spend some time operating the vehicle in a safe area (e.g.
wide and flat) once the QTAC has been properly secured and loaded to ensure
the vehicle operates in a safe manner. If the vehicle does not operate in a safe
manner, immediately recheck the GVWR calculations to ensure that the QTAC
unit is not overloading your vehicle. If the unsafe operation cannot be corrected,
do not carry your QTAC in this fashion.
• When carrying your QTAC unit on the rear rack of an ATV or in the bed of a UTV,
avoid steep side slopes. If an uphill must be traversed, it is recommended that

Page | 9
you back your ATV or UTV up the uphill to avoid the front wheels lifting on the
uphill.
OPERATING YOUR QTAC
Before Starting Up Your QTAC
• Always wear appropriate eye, ear, and body protection when operating your
QTAC unit.
• Ensure that your QTAC has sufficient water in the water tank prior to operation.
The water level can be checked by viewing the water tank site gauge located on
the side of the water tank (Figure 1) If the water tank is low on water, open the
water tank fill tower (Figure 1) and fill the water tank with water.
• Check the pump engine fuel (Figure 3) and oil levels (Figure 3) as needed, fill the
pump engine with fuel and oil as specified in the engine manual that came with
your QTAC. For more information, see the Pump Operation Manual and the
Engine Owner’s Manual.
PUMP OPERATION
Priming the Pump after an Extended Period of Use
The QTAC pumps are a self-priming pump, meaning they do not need to be primed
before every use. However, if the pump is being started after not being in use for more
than 12 hours, it may be necessary to add water to the primer port (Figure 2) to ensure
proper suction. To do so, simply pour water into the primer port until it is full, secure the
cap and start the engine.
Tank Fill Requirements:
MAX FILL PRESSURE: 100 PSI
MAX FILL RATE: 150 GPM

Page | 10
Tank Fill Through the Fill Tower
1. Open the fill tower and fill the tank. (Figure 1)
(For filling the tank by way of draft suction, see page 12)
Pumping Using the Tank Water Supply
1. Ensure that all valves are in the proper position.
a. The tank to pump valve should be open to pull water from the tank.
(Figure 2)
b. The 1” pump to tank should be cracked open slightly. (Figure)
c. The 1” NPSH Discharge should be fully closed. (Figure 2)
2. Start the engine (see next page)
3. Water can now be discharged through the reel line.
(To operate the 1” NPSH discharge, see page 13)
CAUTION! During pumping operations, the operator MUST either a) leave the
pump to tank valve open slightly to bypass water through the pump (reference
Figure 2), or b) leave the nozzle at least partially open at all times. Doing so
ensures that there is always water circulating through the pump to keep it from
overheating. Closing both the nozzle and the pump to tank line will result in
overheating the pump and pump failure.
