Engaged". The second light shall become energized when the chassis parking brake has been set and
when the pump and the chassis transmissions have been shifted completely into the correct gears for
pumping, this light shall be labeled "OK to Pump".
There shall be one (1) green pump system shift indicator light located on the operator's panel. This light
shall only become engaged when the chassis parking brake has been set and when the pump and the
chassis transmissions have been completely shifted into the correct gears. The light shall be located
adjacent to the throttle control and shall be labeled "Warning: Do Not Open Throttle Unless Light Is On".
PRIMING PUMP
There shall be a Waterous, model VPO/VPOS priming pump included with the pump. The priming pump
shall be an electrically driven rotary vane pump mounted firmly within the pump area. The pump shall be
controlled from the pump operator's panel. An indicator light on the pump panel shall show when the
primer motor is engaged. The pump shall be capable of creating suction and discharging water from a lift
of 10 feet through 20 feet of suction hose of the appropriate size, in not more than 30 seconds starting
with the pump dry. It shall be capable of developing a vacuum of 22 inches at an altitude of up to 1000
feet.
WATEROUS VACUUM ACTIVATED PRIMING (VAP) VALVE
There shall be a Waterous model VAP vacuum activated priming valve supplied with the pump. The valve
shall open automatically when the priming system is activated. The valve shall be installed on the pump
or mounted remotely.
PRESSURE GOVERNOR
The apparatus shall be equipped with a Class 1, model 117690 Total Pressure Governor (TPG) that is
connected to the engine Electronic Control Module. The TPG shall operate as a pressure sensor
(regulating) governor (PSG) utilizing the engines J1939 data for optimal resolution and response.
Programmable presets for RPM and pressure settings shall be easily configurable using the TPG's
straightforward menu structure. The TPG shall also include indication of engine RPM, system voltage,
engine oil pressure and engine temperature with audible alarm output for all. The TPG uses the J1939
data bus for engine information requiring no additional sensors to be installed.
The TPG shall also include a pump hour meter to track total hours of pump operation.
INTAKE RELIEF VALVE
There shall be an Elkhart Brass intake relief valve installed on the suction side of the pump. The valve
shall be the preset type, adjustable from 75 to 250 PSI, and shall be designed to prevent vibration from
altering the setting. The relief outlet shall be directed below the pump with the discharge terminating in a
2-1/2" male NST connection. The discharge shall be away from the pump operator and labeled "Do Not
Cap".
MASTER DRAIN VALVE
A Trident manifold drain valve assembly shall be supplied. This drain shall provide the capability to drain
the entire pump by turning a single control. The valve assembly shall consist of a stainless steel plate and
