Suction Line - red lion RL-S50 Owner's Manual

Suction Line

1. Install a new, clean pipe or hose, making sure piping slops
upwards from the water source to the pump to avoid air
pockets in the line.
• Piping should never be smaller than the pump inlet size.
Increase by one size if a large distance is between the
pump and the water source.
NOTE: Increasing size of piping will increase the priming time.
• In cases where a maximum volume of water is required
over a prolonged period, the suction line should be led
almost horizontally to the pump.
2. Install a 90° or 45° elbow on the suction line in cases where
the pump has to be re-primed often and it is not necessary
that a lot of water be delivered.
3. For sump pump applications, clamp the switch to the suction
pipe as shown.
4. For sump pump applications, attach the float and wire
assembly and adjust their positions.
• As the water reaches the top float, the pump will turn
on. When it drops to the bottom float, the pump will
turn off.
5. For effluent applications, pressure diaphragm switches or a mechanical float switch may be used as
alternatives.
• Ensure that the current and voltage specifications match those of the pump.
6. For sump applications, install a strainer.
• Be sure it will be well submerged at all times.
• For effluent applications, a strainer may get clogged. The pump is designed to handle the effluent
and most plumbers prefer not to use one.
7. Tighten all connections thoroughly to avoid air leaks and incomplete prime.
