INTRODUCTION
The Little Giant Remote Vertical Mechanical Switch you have purchased is designed to operate in
applications with limited space, such as small sump basins and laundry trays, as well as in large tanks.
This magnetically activated switch features heavy duty contacts. It is capable of directly controlling pumps
up to 13 amps and is not sensitive to turbulence. The RVMS is designed for water and sewage. The RVMS
is designed for easy attachment and is available in pump down models only.
Read these instructions carefully. Failure to follow these instructions voids all warranty and could result in
bodily harm or property damage. All wiring and plumbing must be permanent and comply with local codes.
Be certain power supplying the pump and switch is removed before servicing.

SAFETY GUIDELINES
MAKE CERTAIN THAT THE UNIT IS DISCONNECTED FROM THE POWER SOURCE BEFORE ATTEMPTING
TO SERVICE OR REMOVE ANY COMPONENT!
Vent tank in accordance with local plumbing codes. Do not install pump switch in locations classified as
hazardous in accordance with the National Electrical Code, ANSI/NFPA 70.
Install unit in accordance with national and local electrical codes.
Do not handle the unit with wet hands or when standing on a wet or damp surface or in water. This unit is
supplied with grounding conductor. To reduce the risk of electrical shock, be certain that it is connected to a
properly grounded grounding type receptacle.
In any installations where property damage and/or personal injury might result from inoperative or leaking pump
due to power outages, discharge line blockage, or any other reason, use a backup system(s) and/or alarm.
Do not removed label from switch cable.

INSTALLATION
PIGGY-BACK PLUG INSTALLATION
Remove piggy-back plug from electrical outlet before installing or servicing the pump and/or switch.
Determine desired activation level and pumping range for your installation (Figure 1). Adjust pumping
range by moving the float stop up or down the rod (Figure 2). Do not mount switch in direct line of
incoming liquid.
Insert clamp through slots in mounting bracket (Figure 2).
Position hose clamp around discharge pipe with bracket gripping tabs against pipe. Ensure that cable
remains on outside of hose clamp (Figure 2).
Tighten hose clamp securely once pump switch is in desired position.
Secure pump cable and switch cable to discharge pipe.
Connect piggy-back plug to outlet (Figure 3).
Connect pump plug to piggy-back plug (Figure 3).
Allow pump to cycle several times to ensure proper pump range. Be certain float mechanism path is
not obstructed.
DIRECT-WIRE INSTALLATION
NOTE:
Piggy-back plug may be removed for direct-wire installation.
Turn off circuit breaker. To avoid hazards, and for convenience, install the double pole disconnect
(breaker) near the pump installation.
Determine desired activation level and pumping range for installation (Figure 1). Adjust pumping range
by moving float stop up or down rod (Figure 2). Do not mount switch in direct line of incoming liquid.
Insert clamp through slots in mounting bracket (Figure 2).

Allow the pump to cycle several times to ensure proper pump range. Be certain float mechanism path
is not obstructed.
TESTING
Without water in sump, plug pump cord into the back
of the switch plug. Plug switch into outlet. Lift float
and listen for pump to operate. Do not run pump for
more than 5 seconds. Next, run water into sump where
pump is installed. Fill the sump to the “on” level and
allow the pump to remove water to the “off” level.
CAUTION: To prevent damage to pump, do not set
switch turn-off level below 2 inches above bottom of
pump base. Also be sure that the pump is secured in its
position so that the float will not become stuck between
the pump and the basin, which could prevent the pump
from turning ON or OFF. Be sure the hose clamp is
secure so that the switch cord does not accidentally slip
and change the pre-set ON/OFF levels.
NOTE: Little Giant cannot be responsible for damages caused by the faulty or negligent installation of this
control. If you feel that you may encounter problems in installing this device, we respectfully suggest you
engage the services of a competent plumber, electrician, or qualified service person.
REPLACEMENT OF RVMS PUMP SWITCH FOR WRS BASINS
CAUTION! Disconnect the unit from the power source before attempting to service or rework any
components.
Disconnect unit from inlet pipe, vent pipe, and discharge pipe.
Remove the 14 machine screws from around the basin cover.
Take off basin cover and remove cord grommet.
Remove old pump switch cord from the cord grommet.
If existing switch is an RVMS model, loosen the stainless-steel clamp that attaches the RVMS pump
switch to the discharge pipe. If existing switch is a diaphragm model, simply unscrew the switch
bracket from the pump and proceed to Step 8.
Slide the RVMS pump switch up and off the discharge pipe. Be careful to note the switch’s orientation
for re-assembly.
Trim 1.25” from the replacement RVMS pump switch stem. Orient the rubber grommet to the location
shown in Figure 5.
Clean out the basin to ensure maximum product performance. Replace the RVMS pump switch in the
reverse order in which it was removed.
