Before calibrating the pump, be sure that air and fluid
are supplied to the system.
Prime the system to make sure that there is no air in
the pump. Put the system into Standby mode.
1. Press the Fill button. The system will
automatically fill.
Be sure the gun trigger is released. During the
test the fluid line will be pressurized to the active
preset value. No air will be sent to the gun.
2. Press the Stall Test button. The pump will
pressurize and the system will monitor the linear
sensor to look for leaks with the pump at the top
if the pump stroke. The screen will display the
text, "Stall Test" and "Test In Progress."
The test takes about 1 minute. If the test is
successful, a confirmation displays on the
screen. The system will return to Standby.
3. Press the Spray button. Dispense between
700-1000 cc so that the pump is about 1/4 full.
4. Be sure the gun trigger is released and press
the Stall Test button. The system will now be
tested with the pump near the bottom of the
pump stroke.
The test takes about 1 minute. If the test is
successful, a confirmation displays on the
screen. The system will return to Standby.
Note
In addition to the HydroShield, this test
checks the hose connections and gun. If
the test fails it should be repeated with the
ball valve on the inlet to the fluid pressure
regulator in the closed position. Then the test
will only check the pump and connections
inside the HydroShield.
