Physical Installation

Risk of severe injury or death by electrical shock.
• Always disconnect the electrical power before touching the pump or discharge.
Risk of damage to pump or other equipment.
• Do not install the check valve in a vertical position, as solids may settle in the valve and prevent the valve from
opening on start-up. For best performance of the check valve when handling solids, install it in a horizontal posi-
tion or at an angle of no more than 45°.
• When a check valve is used, drill a relief hole (1/8" or 3/16" in diameter) in the discharge pipe. This hole should be
located below the floor line between the pump discharge and the check valve. Unless such a relief hole is pro-
vided, the pump could "air lock" and will not pump water even though it will run.
• Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump
to fail, motor bearing failures, etc.
NOTE: To test the operation before installing, refer to
1. Install the pump in the center of a clean, suitable gas-tight basin that is at least 18" (45.7 cm) deep.
• For RL-SC33V and RL-SC50V models, the basin must be 15" (38.1 cm) in diameter.
• For RL-SC33T and RL-SC50T models, the basin must be 18" (45.7 cm) in diameter.
• Place as close as possible to a water source to minimize suction piping length.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding,
and equipment drainage.
• Never place the pump directly on clay, earth, or gravel surfaces.
• Ensure sump is clean and free of nails, gravel, string, cloth, or other debris before installing.
IMPORTANT: Do not attempt to restrict the intake side of the pump.
2. Connect discharge piping, using pipe joint compound at all connections.
• The discharge pipe should be as short as possible and contain as few elbows as possible.
• Piping should be the same diameter as the discharge port.
• If reduced flow rates are required, place a valve on the discharge side of the pump.
3. Install a union in the discharge line just above the basin cover.
4. Install a free flow check valve in the discharge line that will easily pass 3/4" solids.
5. Tape the pump cords to the discharge piping with electrical tape.
6. Add an air relief bleed hole to the pump's discharge plumbing. Refer to
page 4.
7. Refer to "Electrical Connections" on page 6
8. Confirm that the pump is functioning as intended. Refer to
NOTE: It is normal for a stream of water to spray from the air relief bleed hole in the pump's
plumbing. Verify that this spray is captured within the basin.
9. Place cover over basin.
