Preventive Maintenance
❑
1. Prepare to pump from the onboard water tank, having the discharge flow
directed back to the water tank.
2. Increase the pump pressure up to normal oper-
ating pressure as indicated on the master pres-
sure gauge per normal operating procedures.
3. Turn the relief valve hand wheel counterclock-
wise until the valve opens. The relief valve is
open when the AMBER indicator light is ON and
the pressure begins to drop. (See Figure 4-1:
“TPM Relief Valve Control.”)
4. Turn the relief valve hand wheel clockwise. The
pressure should return. Cycle the relief valve a
few times to ensure that the hand wheel turns
freely. Observe the pressure gauge and indi-
cator light for proper valve operation.
5. Return the relief valve hand wheel and the
apparatus to normal operational condition.
Priming System
Run primer weekly to ensure proper operation.
With all the valves closed and capped, actuate the primer and make sure
the intake gauge drops below zero (0). The gauge should hold below zero.
If air leaks are heard or the gauge bounces back up to zero (0), the pump or
valves require service.
