9.8 Replacing the DP/SP Priming Valve Knob Seal
Replace the seal in the priming valve knob if there is leakage around the valve
threads when the valve is open or if the waste port leaks when the valve is closed.
1. Click Motor on the pump Control panel in Chromeleon or Chromeleon
Xpress to turn off the pump flow.
2. Begin monitoring the Current Pressure reading on the Control panel. When
the system pressure reaches zero, do the following:
• Disconnect the pump from the software by clearing the Connected check
box on the Control panel.
• Press the POWER button on the front of the DP/SP for 2 seconds to turn
off the pump.
3. Open the front door of the DP/SP to access the mechanical components.
4. Use the handles on the component mounting panel to pull the panel forward
until it reaches the stop.
NOTE On newer pumps, three red Phillips screws are installed
on the component mounting panel before shipment from
the factory. If the mounting panel does not move freely,
make sure these screws have been removed.
