Water Tank
500 Gallon Water Tank
Foam TAnk
20 Gallon Foam Tank
Fuel Tank
65 Gallon Fuel Tank
DEF Tank
4.5 Gallon DEF tank
High Exhaust System Temperature
The HEST light illuminates when exhaust is over
977°
DEF Indicator Light
SOLID – Between 1/4 and 1/8 full
* FLASHING – Below 1/8 full
If the DEF indicator light and any
or all of these additional indicators
come on, the DEF tank is below
1/4 gallon, and should be refilled
immediately.
Warm Water Decon System
- Separate 18-gallon water tank. Located above
Cross lay compartment. - Two water heaters, 12v & 120v.
- Designed to keep water tank warm 24/7 and
ready for use immediately. - Full tank of cold water takes approximately 45-
60 minutes to fully warm on shore power.
Onspot automatic
chains Operation
Engage when traveling between 2-25 mph just
before reaching slippery conditions.
– Do not exceed 35 mph.
– Can stop on chains and start again, as long as
switch is still in the active position.
Ladder Rack
The Extension Ladder is Now a 28’ 2 section ladder, it weighs 87
lbs. Compared to a 35’ 3 section weighing 129 lbs.
Cavitation Protection
If PSG cannot recover, it switches to RPM Limit Mode.
* Pressure LED stays on.
* Displays flash and states Operator / RPM Limit.
* Pressure Setting Does not change, but Preset is disabled.
* PSG acts like manual throttle.
* If pressure recovers or operator corrects, returns to Pressure
Control Mode – normal operation.
* If it does not recover but stays above 45 psi, remains in RPM
Limit Mode.
If pressure falls below 45 psi, but above 15 psi, enters
Lo Water Mode
– Displays Lo Water
– Sets rpm at 1100
– After seven seconds goes to idle.
* If pressure falls below 15 psi, enters No Water Mode
– Displays No Water
– Goes to idle.
Pressure correction
In the RPM Limit, Lo Water, No Water Modes,
if the pressure recovers, it goes back to
Pressure Control. If the operator intervenes
and brings the RPMs to a point where it is not
in cavitation, it goes back to the Pressure
Control Mode.
* If it goes to idle and stays more than 3
minutes, it enters the Idle mode and cancels
the pressure setting.
Intake Relief Valves
will be left preset at
190.
– May cause vacuum leak when
drafting.
Booster Reel
Located on Driver’s side
pump panel.
* 200’ of 1” hose.
* Very high friction loss
and designed for lower
flows (up to 60 GPM).
* Friction loss for 30gpm
is 37 psi per 50’
section.
Foam System
- Foam is plumbed to all crosslays, and
the hose reel. - System automatically injects correct
amount of foam to match flow. - Preset at 0.4% for Class B fires.
Reduce to 0.1% for Class A fires. - Can flow 3,000 gpm at 0.4%.
- 20-gallon tank 7,500 gallons of
solution at 0.4%.
