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 flanges (Figure 4 Item 2), located at the bottom of the water tank

on each side. The flanges have been machined to accept a variety of mounting
hardware options.
2. Strapping the QTAC down through the strap guides (Figure 4 Item 1), located at the
top of the water tank. Only one tie-down configuration is required to mount the QTAC
(either the inside or outside configuration).
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
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, Item 5) If the water tank is low on water,
open the water tank fill lid (Figure 1, Item 2) and fill the water tank with water.
•Check the pump engine fuel (Figure 3, Item 3) and oil levels (Figure 3, Item 7) 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 Honda Owner’s Manual.
•Prime the pump as needed by removing the plug at the pump prime port and
filling the pump head with clean water (Figure 2, Item 1) If the pump has been run
recently with plain water, this step will likely not be needed as the pump will retain
its prime for some time. For more information, see the Pump Operation Manual.
PUMP OPERATION
Tank Fill Requirements:
MAX FILL PRESSURE: 100 PSI
MAX FILL RATE: 150 GPM
Tank Fill Through the Fill Tower
1. Open the water fill lid and fill the tank. (Figure 1, Item 2)

Page | 9
Starting the Engine
1. Ensure that the engine has a sufficient amount of fuel in the gas tank. (Figure 3,
Item 3)
2. Turn the Engine switch to the on position. (Figure 3, Item 6)
3. If the Honda engine is cold, apply the choke. (Figure 3, Item 1)
4. Prime the pump engine with fuel by pumping the carburetor fuel primer. (Figure 3,
Item 2)
5. Pull the hand starter cord until the engine starts. (Figure 3, Item 4)
6. Apply throttle (Figure 3, Item 5) and decrease the choke until it is no longer
needed. The output of the pump is regulated by how much throttle is applied, as
well as the shut-off at the nozzle.
Pumping Using the Tank Water Supply
1. The pump intake selection valve should be open to pull water from the tank.
(Figure 2, Item 2)
2. Start the engine (see previous page)
3. Water can now be discharged through the discharge hose.
DRAFT PROCEDURES
Drafting From an Auxiliary Water Source
Your QTAC has the ability to draft water from an auxiliary water source. The operator
can draft straight into the pump and out a discharge line, bypassing the tank

Page | 10
Pumping While Drafting From an Auxiliary Water Source
1. Connect the draft hose; Remove the Camlock cap covering the draft hose port. Secure
the draft hose Camlock coupling to the draft hose port. (Figure 2, Item 3)
2. The pump intake selection valve should be set to pull water from draft port.
(Figure 2, Item 2)
3. Place the brass foot valve connected to the end of the draft hose into the water
source. For faster priming submerge and fill the draft hose. Make sure not to place
the foot valve in mud or dirt, as it will suck debris into the pump. Always elevate
the valve off the bottom of the water source to reduce the chances of debris
intake.
4. Open the hose reel nozzle slightly to ensure that water is allowed to run through
the pump after the engine is started.
5. Start the engine (see Page 9) and increase the throttle setting until you see water
entering the draft hose and being pulled into the pump head.
6. Use the discharge line to carry out suppression operations.
NOTE: The 20S is equipped with a cooler line, that returns water to the tank from
the discharge port, while drafting, the tank will eventually fill and overflow.
STOPPING YOUR QTAC
1. If opened, gradually close the shut-off valve at the end of the discharge hose
2. Decrease the throttle on the pump engine to the idle position (Figure 3, Item 4).
3. Set the engine switch to the “OFF” position (Figure 3, Item 6)
