23. Pump out well (if necessary):
Direct pump’s discharge to appropriate location
not connected to system and press
Pump Out.
The pump will run at 45 Hz.
Run the Drive in this mode until the well discharge
runs clear, then press
STOP
button to stop Drive.
Risk of explosion. In
Pump Out
mode, pump runs at a constant speed, which can
cause very high pressure if flow is restricted.
4. Verify installation: Make sure that the system
has properly-sized, pressure-relief valve and
pressure tank.
Make sure pressure tank’s precharge is correct.
(See Table 7).
Make sure pump discharge is connected to
system.
5. System Start:
A. Open valves at the ends of lines so that air
will escape during pressurization.
B. Press
Auto Start;
close valves at the ends of
lines after all air has escaped.
C. The system goes into
Constant Pressure
Operation
as soon as the transducer
registers the
Dry Run Sensitivity
parameter
(default is 68 kPa). If system pressure does
not reach thatkPa value within 3 minutes,
the Drive will stop. Press
Auto Start
again to
restart line fill. If longer priming or line fill
time is required, adjust
Fill Time
parameter.
(See Table 9).
Changing a Parameter Value
This procedure works for ANY parameter.
A. Press MAINMENU button.
B. Follow the keypress sequence shown in
Figure12:
A shorthand way to remember this is:
• Press ENTER to change a value
• Press ENTER again to save it
• If new value is not saved, any screen change will
result in the loss of the new value.
Table 9 lists all available commands and
parameters for the PENTEK INTELLIDRIVE.
