OPERATION: Manual Priming Control
The manual fire pump primer is operated simply by increasing the engine speed to a maximum of 1000 RPM and depressing the push
button on the panel. Hold the button down until the discharge pressure gauge begins to rise. The primer will stop operating when the push
button is released. The push button will operate the primer regardless of whether the fire pump is engaged or not.
• Depressing the
Push To Prime
button directs air to the primer inlet.
• An internal valve to the fire pump is opened with air pressure from the chassis air brake system when the button is depressed.
• Vacuum for drafting is created by air flowing through multi-stage internal venturi nozzles.
• The Primer Control Valve has no water, plumbing or electrical lines.
• Never run a dry pump at engine speeds above 1200 RPM for more than 45 seconds in accordance with the operating instructions
provided from the fire pump manufacturer.
• NOTE
: It is recommended that the
Push Button Control
be depressed monthly to exercise the spring and seals
. The fire pump
does not have to be engaged during this process. This also applies to any other intake Push Button Controls you may have.
or equivalent O-Ring safe lubricant should be applied annually to lubricate the mechanism. It is available at
or
through a local automotive parts supplier.
