This instruction sheet provides you with the information required to safely own and operate your Red Lion pump. Retain these instructions for future reference. The Red Lion pump you have purchased is of the highest quality workmanship and material, and has been engineered to give you long and reliable service. Red Lion pumps are carefully tested, inspected, and packaged to ensure safe delivery and operation. Please examine your pump carefully to ensure that no damage occurred during shipment. If damage has occurred, please contact the place of purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL , OPERATE , OR SERVICE YOUR Red Lion PUMP. KNOW THE PUMP’S APPLICATION, LIMITATIONS, AND POTENTIAL HAZARDS. PROTECT YOURSELF AND OTHERS BY OBSERVING ALL SAFETY INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
Please refer to your Red lion Sump Pump owner’s manual for installation and operation of your sump pump. These instructions cover set-up of the dual pumping system only.

ANNUAL MANDATORY TESTING IS REQUIRED.
1. Remove dual pump system from sump pit.
2. Inspect the sump pit and remove any debris, leaves, etc. that may clog the pumps. Remove pumps if necessary.
3. Return dual pumping system to sump pit, and test following the instructions provided with pumps. See sections on Installation and Operation as well as Testing.
To lengthen the lifespan of your dual sump pump system we recommend reversing the primary and secondary pumps annually (see Fig. 2). You will need to move the float stop from the primary pump to the secondary pump which will reverse the order that the pumps activate.
- Pipe assembly (Fig. 1)
- 2 check valves with stainless steel clamps
- 1 rubber float stop
Pumps should be connected or wired to their 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.
Ensure pumps are installed on a hard level surface. Never place pumps directly on clay, earth, or gravel surfaces.
When the pump is installed in a basin with a sealed cover, float switch operation cannot be observed. The cover usually will have a spare hold that is blocked with a rubber plug. This plug can be removed and switch operation can be observed.
- Plug power cord into a grounded receptacle with voltage consistent with pump voltage as indicated on pump nameplate.
- Run water into basin until pump starts. IT IS NORMAL FOR ONLY ONE PUMP TO RUN – THE SECONDARY UNIT ACTS AS A BACKUP IF THE PRIMARY UNIT FAILS OR CAN’T KEEP UP TO THE WATER LEVEL.
- Be sure gate valve in discharge line is open.
- Allow pump to operate through several on-off cycles. If pump does not operate properly, consult the troubleshooting guide found in the pump’s owner’s manual. If trouble cannot be located, consult your pump dealer or take pump to a Red Lion authorized service center.
PLEASE REFER TO THE PUMP’S OWNER’S MANUAL FOR FURTHER SAFETY GUIDELINES AND INSTRUCTIONS!
If you have purchased this item with the pump kit you will also receive two almost identical cast iron sump pumps – RL-SC33V. The “Primary” pump
has a rubber stop on the control switch rod above the float (Fig. 2). A spare stop has been included with kit should the need arise to install this on
another RL-SC33V pump. This makes this pump the primary pump (Fig. 3).
Step 1: Unpack the plumbing kit and each sump pump. Store the extra float stop in a safe place (see Fig. 1).
Step 2: Using PTFE tape, secure the black check valves into each sump pump by threading them into the discharge of each pump (Fig. 4).
Step 3: Align the pumps so the two discharge units line up with the piping as shown in (Fig. 5). Install the ABS piping into each check valve (Fig. 6).
DO NOT TIGHTEN THE CLAMPS YET.
Step 4: Twist the pump to eliminate the spacing between them (Fig. 7). Once pumps are tight against the piping, tighten the clamps at both the top and the bottom of each piping unit using a flat head screwdriver.
Step 5: Install into the sump pit. Diameter of the sump pit must be a minimum of 18” (Fig. 8). Plug both units into GFCI electrical outlet. Test the GFCI outlet to pressing the Test button. Be sure to reset the GFCI by pressing the Reset switch.
RISK OF ELECTRIC SHOCK:
Do not use an extension cord.
When a pump is in a basin or lift station, do not touch motor, pipes, or water until unit is unplugged or shut 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.
Do not modify the power cord except to shorten it 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 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 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 ATMOSPHERES 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 opump is immersed in water. Also during rain storms, water may be present in the surrounding area of the pump.
Use caution to prevent bodily injury when working near the pump:
a. Remove the plug from the receptacle prior to touching, servicing, or repairing the pump.
b. To minimize possible fatal electrical shock hazard, use extreme care when changing fuses. Do not stand in water while changing fuses or
insert your finger into the fuse socket.
4. Do not operate the pump in a dry basin. This will cause the pump to become extremely hot, causing burns if touched and/or damage to 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 National Electrical Code all pump must be wired with 14 AWG or larger wire. For runs to 250’, 14 AWG wire is sufficient. For longer runs, consult a qualified electrical or the factory.
