WARNING
     This pump is supplied
with a grounding conductor and/or grounding-type attachment
plug. To reduce the risk of electric shock, be certain that it is
connected to a properly grounded grounding-type receptacle.
Your 115 V pump is equipped with a 3-prong electrical plug. The
third prong is to ground the pump to prevent possible electrical
shock hazard. Do not remove the third prong from the plug. A
separate branch circuit is recommended. Do not use an extension
cord.
When a pump is in a basin, etc., do not touch motor, pipes or water
until unit is unplugged or shut off. If your installation has water
or moisture present, do not touch wet area until all power has
been turned off. If shut-off box is not accessible, call the electric
company to shut off service to the house, or call your local fire
department for instructions. Failure to follow this warning can result
in fatal electrical shock.
The flexible PVC jacketed cord assembly mounted to the pump
must not be modified in any way, with the exception of shortening
the cord to fit into a control panel. Any splice between the pump and
the control panel must be made within a junction box and mounted
outside of the basin and comply with the National Electrical Code.
DO NOT use the power cord for lifting the pump.
The pump motor is equipped with an automatic resetting thermal
protector and may restart unexpectedly. Protector tripping is an
indication of motor overloading as a result of operating the pump
at low heads (low discharge restriction), excessively high or low
voltage, inadequate wiring, incorrect motor connections, or a
defective motor or pump.
1. Read all instructions and safety guidelines thoroughly. Failure to
follow the guidelines and the instructions could result in serious
bodily injury and/or property damage.
2. DO NOT USE TO PUMP FLAMMABLE OR EXPLOSIVE FLUIDS
SUCH AS GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT
USE IN EXPLOSIVE ATMOSHPHERES OR HAZARDOUS
LOCATIONS AS CLASSIFIED BY NEC, ANSI/NFPA70. FAILURE
TO FOLLOW THIS WARNING CAN RESULT IN PERSONAL
INJURY AND/OR PROPERTY DAMAGE.
3. During normal operation the pump is immersed in water. Also,
during rain storms, water may be present in the surrounding
area of the pump. Caution must be used to prevent bodily injury
when working near the pump:
a. The plug must be removed from the receptacle prior
to touching, servicing, or repairing the pump.
b. To minimize possible fatal electrical shock hazard,
extreme care should be used when changing the fuses.
Do not stand in water while changing fuses or insert your
finger into the fuse socket.
4. Do not run the pump in a dry basin. If the pump is run in a dry
basin, the surface temperature of the pump will rise to a high
level. This high level could cause skin burns if the pump is
touched and will cause serious damage to your pump.
5. Do not oil the motor. The pump housing is sealed. High grade
dielectric oil devoid of water has been put into the motor
housing at the factory. Use of other oil could cause serious
electric shock and/or permanent damage to the pump.
6. This pump’s motor housing is filled with a dielectric lubricant
at the factory for optimum motor heat transfer and lifetime
lubrication of the bearings. Use of any other lubricant could
cause damage and void the warranty. This lubricant is non-
toxic; however, if it escapes the motor housing it should be
removed from the surface quickly by placing newspapers or
other absorbent material on the water surface to soak it up, so
aquatic life is undisturbed.
7. In any installation where property damage and/or personal injury
might result from an inoperative or leaking pump due to power
outages, discharge line blockage, or any other reason, a backup
system(s) and/or alarm should be used.

Pump must be installed in a suitable gas-tight basin which is at least
18" in diameter and 24" deep. It must be sealed and vented to meet
local, state, and federal plumbing codes. Pump must be placed on
a hard level surface. Never place pump directly on clay, earth, or
gravel surfaces. A check valve must be used in the discharge line to
prevent back flow of liquid into the basin. The check valve should
be a free flow valve that will easily pass solids.

When a check valve is used, drill a 3/16" hole in the discharge pipe
approximately 1" to 2" above the pump discharge and below the
check valve to prevent air locking of the pump.

Check local electrical and building codes before installation. The
installation must be in accordance with their regulations as well
as the most recent National Electrical Code (NEC). To conform to
the NEC, all pumps must be wired with 14 AWG or larger wire. For
runs to 250', 14 AWG wire is sufficient. For longer runs consult a
qualified electrician or the factory. Pump should be connected or
wired to its own circuit with no other outlets or equipment in the
circuit line. Fuses and circuit breaker should be of ample capacity
in the electrical circuit.

The RF series pumps are equipped with a remote float switch level
control. For automatic operation, the pump must be plugged or
wired into this remote float switch. Pump will run continuously if
plugged directly into an electrical outlet. When the level rises in
the basin, the cylinder floats up with the level. When the cylinder
position is at an angle of about 45°, the switch activates and starts
the pump motor. As the level draws down, the cylinder floats down
and when it is again at an angle of about 45°, the switch deactivates
and the pump motor stops.
