The large side intakes are equipped with manually operated valves, which are opened
or closed with a hand wheel.
As mentioned earlier, the L.D.H. discharges have hand wheel operated valves, which
prevent rapid opening or closing. The deck gun has a valve, which requires extra effort
to open or close to comply with this standard.
BLEEDER VALVES ON INTAKES:
The large side intake valves are quipped with bleeder valves on the outboard side of the
valve. The front intake has 2 drain valves, one in front and one behind the front axle,
and the rear intake has a bleeder valve handle below the rear intake port.
When receiving water into any of these intakes through 4" hose, such as quick water or
in-line operations, these bleeders should be left open until a steady flow of water is
present before opening the intake valve. This will prevent air from being forced into
the pump, which can cause damage.
ELECTRONIC PRESSURE GOVERNOR:
Earlier apparatus equipped with electronic pressure governors utilized the
Captain
model, which contained the pump controls in one panel and the engine data in a
separate panel. The
Fire Commander II,
incorporates both functions into a single unit.
The operations of both models are identical with the exception of a few minor
differences.
Due to the extensive information required for the safe and efficient operation of the
Electronic Fire Commander II
, a separate manual is being supplied with your new
apparatus to assist engineers and certified extra drivers in becoming familiar with this
device. It is recommended that a copy of the manual be kept in the apparatus as a
reference.
All new engines are being equipped with E
electronic pressure governors to control the
fire pump.

panel for the
Fire Commander II,
pressure
governor installed on this apparatus.
Manufactured by
Class 1,
it is designed to
operate pumps powered by
Detroit Diesel
engines.
