INTRODUCTION
The Little Giant Model RFSN-16 Liquid Level Control is designed
to be used with Little Giant manual sump, effluent, and sewage
pumps, or other pumps rated within electrical limits noted below.
This control uses a non-mercury switch sealed in plastic float cylin-
der. The switch is activated when the fluid level in the basin causes
the cylinder to float to an approximate 45° angle. This causes the
switch to activate and in turn causes the pump to start.

WARNING: Risk of electrical shock! This switch is supplied with a
grounded type attachment plug. The pump used with this switch
must also be equipped with a grounding type attachment plug.
DO NOT REMOVE THE GROUNDING PIN FROM THE PLUG.
To reduce risk of electrical shock, be certain that the switch is
connected only to a properly grounded receptacle. For direct wire
installation (without piggyback plug), refer to Figure 3.
during normal operation the switch and pump are in contact with
water. also, water may be present in the surrounding area of the
switch and pump. exercise extreme caution when working near
these areas.

by rising water. Refer to the National electrical Code and local
requirements. a separate branch circuit is recommended for
each pump. do not use an extension cord.

circuit breaker prior to touching, servicing or repairing the
switch or pump.
3. do not stand in water while changing fuses or resetting circuit
breakers or repairing the switch.

INSTALLATION
(in 18" minimum dia. basins)
1. DECIDE ON THE PUMPING
INSTALLATION: Refer to the pumping range chart below to
determine the cable length required from mounting point to
float. To insure proper installation, a 3.5" minimum tether length
is recommended.
2. INSTALLATION (refer to Figure 1): attach float cable to large
mounting strap using the two small cable ties provided. Space
small ties on each side of clear friction pad, a minimum of one
inch apart (see Figure 2). Then fasten the large strap securely
to the discharge pipe or other similar mounting. NOTE: The
large strap and two small cable ties are releasable, which
permits readjustment or removal of either strap or ties.
3. TESTING
a. without water present, plug pump cord into switch "piggy-
back" plug (refer to Figure 4).
b. plug piggyback plug into properly grounded outlet.
c. Lift float and listen for pump to operate.
