Hose Connections
1. Connect a 3-inch hose to the discharge port on the
pump as shown in Figure 8. Make sure that hose is
attached correctly to the discharge port.
attaching Lifting rope
1. Attach a suitable lifting cable (rope) to the carrying
handle (Figure 12) on the pump and lower the pump
into place. For applications where there is an excessive
amount of mud, grit or silt, the use of a support platform
is desirable. When pumping water from swimming pool
type applications where there is little or no debris, the
support platform is not required.

Upright Position (Correct)
2. Make sure the pump is always placed in an upright
position (Figure 12), and not tilted (Figure 13). Never
position the pump directly on a soft, loose bottom.
Remember to attain maximum pumping capacity and
prevent excessive wear. Position the pump so it will not
burrow itself into sand or clay.

1. Make sure circuit breaker supplying power to pump
motor is in the oFF position.
2. Insert the L6-20P power cable plug (Figure 12) into
the appropriate power source receptacle. The correct
source voltage for this pump is 230 VAC, 60 Hz, single-
phase.
3. If all of the pump's electrical requirements have been
met, place the circuit breaker or power ON/OFF switch
in the on position.
4. Wait a few seconds and water should begin to flow
from the discharge hose.
5. If water is not flowing from the discharge hose or not
flowing freely after a few minutes, place the circuit
breaker or ON/OFF switch in the oFF position and
check the system for leaks.
SUBMERSIBLE PUMP
NOTICE
When connecting the pump directly to a power source
(no control box), it is recommended that personnel
monitor the pump while in operation. Severe pump
damage can occur if left unattended.
For unattended operation Multiquip recommends the
use of either the CB6 or CB200 control box.
