Honda WSP50 Pump Usage and Installation Guide

Honda_WSP50What can you do with a WSP50 submersible pump? How do you use it? This guide will help you find the correct application for this pump, install it correctly and use it safely.

Safety Disclaimer

Always disconnect the power source when doing anything with this pump, from changing its position to taking it apart.

Never modify or remove the casings on this pump. They are designed to protect accidents involving the moving parts these pieces over, and tampering with them could cause a serious injury.

Never lift the pump by the power cable. The handle is designed so that a rope or cable can be tied to it.

What Can This Pump be Used For?

This pump can handle dirty and semi-dirty water as well as water with suspended debris up to two inches (50 mm) in diameter. The WSP50 can be used for continuous duty, but only if fully submerged: the motor is cooled by the surrounding fluid. Speaking of which, this unit has a built in thermal switch that will automatically shut off the motor if it gets too hot, which will generally occur if fluid temperatures rise above 104°F (40°C.) Pumping flammable liquids or corrosive liquids including acids and sea water will damage this pump.

Common applications that meet these requirements include draining basements, garages, swimming pools, tanks, basins, fountains, drains, cesspools, sewage collection drains, excavations and rainwater tanks.

Installing in a Fixed Location

The pump must be placed on a level surface. It should be lowered into place using a cable attached to the pump handle.

The pump delivery will need to be connected to a drain using rigid G2 (two inch interior diameter) metal or plastic pipes with a no-return valve fitted to the delivery pipe.

Installing Temporarily

As with a permanent installation, the pump must be placed on a level surface and it should be lowered into place using a cable attached to the pump handle.

The pump delivery will need to be connected to a drain using G2 (two inch interior diameter) flexible pipes and a no-return valve fitted to the delivery pipe. Couplings can also be used as part of the installation so long as they have the same diameter as the pipes.

Connection the Pump to an Electric Connection

The pump includes a 25 foot grounded three prong electric cable. Since the pump depends on the plug connection to ground both the inside and case of the pump, it should only be plugged into a properly grounded three prong receptacle. Honda recommends using the pump with a high sensitivity differential switch, such as a GFCI outlet, to shut off the pump in case of a short.

Adjusting for Operation

This pump is a self-contained unit, so the only thing that needs to be checked is the length of the float switch cable: it should be long enough to shut off the pump once the minimum desired water level has been reached. The minimum water level can be adjusted by moving the float cable into or out of the loop on the side of the pump handle. The longer the cable is between the switch and the loop, the lower the water level has to be to activate the float switch, shutting off the pump.

Start-Up and Use

The pump will start immediately once it receives power, and then shut off once the float reaches the minimum water level. If the pump shuts off before the water level is low enough to activate the float switch, the pump may be overheating, the impeller may be jammed by debris, the intake pipe is clogged or the electrical connection may have been lost.
