PAGE 14 — ST1/ST1F SUBMERSIBLE PUMP • OPERATION AND PARTS MANUAL — REV. #0 (02/01/21)
See for standard ST1F Operation Setup.
1. Prepare the pump for Float Switch Operations. The
Float Switch activates based upon the angle of the float
in the water source. Ensure there is sufficient lateral
distance to employ the float horizontally (@ 13”).
Pump OFF (A and B): due to the position of the float,
the internal metal ball has made contact cutting off
electrical power.
Pump ON (C): the water level is high enough to permit
the float to rise (contact broken) permitting the motor
to engage.
The pump can also be used without the Float by
securing the assembly to the top of the pump with a
cord or zip tie (X).
2. Securely thread a ¾” garden hose or ¾” GHT pipe onto
the discharge port.
3. Orient the hose/pipe in manner that limits extreme
bends, kinks, or twists. Ensure the hose/pipe discharge
end is positioned where you desire the flow of water
to travel.
4. Tie a rope or cord (not supplied) around the carry
handle to lower and retrieve the pump from the water
source.
5. Consider using a support platform base (not supplied)
for the pump to sit upon to keep the suction inlet
from directly engaging with any silty, sandy bottom
conditions.
CAUTION
Applying incorrect power (voltage phasing) to the
submersible pump can cause severe damage to the
pump.
Make sure that the correct voltage and phase are
transferred to the pump at all times.
DANGER
NEVER
grab or touch a live power
cord.
DO NOT
stand in water when
connecting the pump’s power cord into
a voltage source. The possibility exists
of electrical shock, electrocution and
possibly death!

6. Slowly lower the pump to its operating position ensuring
that it remains vertical. Ensure that the pump remains
submerged as long as possible, and do not allow the
pump to run dry for more than a minute.
7. Connect to the pump’s power cord to the proper
electrical source. The pump will automatically operate
as soon as power is connected & the Float Switch is
oriented for desired operations.
8. Once electrical power is introduced, the water should
flow from the discharge hose/pipe within seconds.
Check to the flow rate to be steady and continuous.
9. Once the watering/dewatering operation is complete:
disconnect the power source, pull the pump from its
position and allow it to drain completely. Remove
the discharge hose/pipe, and store the pump in
temperatures above freezing.
10. An optimum power source for consideration would be
a GFCI receptacle.
11. If an extension power cord is necessary, refer to Table 3
for Recommended Extension Cord Data, and consider
purchasing and installing an Extension Cord Safety
Cover with Waterproof Seal.
