 TurboDraft
Set-Up
•
The unit requires a 2-1/2 inch discharge line from the fire truck
and a 5 inch supply line to return water flow to the fire pump.
•
The lines should be stretched from the truck to the water's edge
avoiding sharp bends and kinks.
•
Before connecting hoses to the TurboDraft, inspect the unit to be
sure no debris has entered the inlet or discharge openings.
•
Connect the 2-1/2 inch line to a discharge from the pump and to
the TurboDraft unit, as shown below.
•
Connect a 5 inch LDH supply line to pump intake valve and TurboDraft
unit, as shown below.
•
Care should be taken to insure all connections are tight and secure.
A rope or webbing may be attached to the handle and secured, however,
this is not critical because the unit may be retrieved using the
hose lines.
•
Submerge in 2 to 3 feet of standing water, with the screen/strainer
facing up, 1 to 1-1/2 feet of moving water.
 •
After the above steps are complete the unit is ready to be put into
operation.
•
Engine should be placed into pump gear and truck prepared for pumping
operations.
•
The intake valve should be closed.
•
Open the bleeder on the suction intake valve to allow any air in
the hose to be vented.
•
Open the tank-to-pump valve.
•
Increase the engine pressure to 175 PSIG.
•
Open the 2-1/2 inch discharge supplying the TurboDraft unit and
maintain discharge pressure at 175 PSIG. This is required to start
suction flow back to the truck.
•
As the 2-1/2 inch line is charged, the 5 inch line will immediately
start to fill.
•
Close the bleeder once water reaches it and slowly open the suction
intake valve.
•
The water supply is now established.
•
Close the tank-to-pump valve.
 •
At this point the truck's tank should be refilled. Open the tank
fill valve 1/4 to 1/2 open and allow tank to fill. The truck tank
should always be kept full to allow the water supply to be re-established,
if necessary.
•
With 100 ft. of 5 inch hose, it should take approximately 100-250
gallons of water to establish a water supply to the truck.
•
Once tank is full, close tank fill valve.
•
Slowly open required discharge valve(s).
•
Maintain the required pressure (see Chart
1) on the TurboDraft 2-1/2 inch line at all times.
•
During the use of the TurboDraft unit, care should be taken not
to exceed supply source availability. This will cause the supply
line from unit to collapse. (see Flow
Chart 1).
•
Supply line (5 inch LDH) from the unit should always be monitored.
Maximum flow from the TurboDraft unit is achieved when the supply
line starts to become soft.
•
If
the supply line flow is exceeded and the line collapses, simply
open the tank-to-pump valve and decrease the discharge flow until
the supply line recovers. Once stabilized, close the tank-to-pump
valve and top off the tank as soon as possible.
