OPERATION
AUTO/STANDBY MODE
In the automatic mode:
Engine senses and adjusts RPMs automatically to match
the application's load and speed requirements.
Engine keeps running at higher RPM right after start
which makes speedy pump priming. It then goes back
automatically to normal RPM, in 15 seconds after start
for smooth flow discharging.
Engine turns off automatically one minute after water is
fully pumped, even if unattended, which prevents No-
Load running and useless fuel consumption.
1. Turn the DRAIN/FILL switch to the
OFF position
(Figure 13).
Figure 13. DRAIN/FILL Switch
2. Make sure that the engine fuel valve lever is in the
ON
position (Figure 9).
3. Turn the starter switch to the
START position
(Figure 11).
4. Engine will run at the most suitable RPM as it senses
the job-load.
AUTO/DRAIN OPERATION
Pump starts draining water automatically at the set high
level, utilizing float switches, then turns off at the set low
level. When the water reaches the set high level again,
pump starts draining again.

NOTICE
If automatic mode is selected, the pump flow cannot
be controlled by the flow control switch.
1. Prepare and connect suction hose and discharge hose
to the suction port/discharge port of pump (Figure 3).
Make sure suction hose is placed deep into the water
source and discharge hose is not kinked and lays flat.
2. Connect the terminal plugs of float switches to the float
control ports on the control panel (Figure 14)
Figure 14. Float Control Ports
3. Set the top (drain) and bottom (stop) water levels you
expect to control with the float switches (Figure 15).
