Product Features

- The Surge protective devices(SPDs), suitable for residential,commercial and industrial appications, are designed to limit transient overvoltage and run-off lightning currents.

- It provides reliable protection from the destructive effects of lightning and switching

overvoltages.

Function:

- are lightning current arrsters, they can handle and divert high energy from lightning.

-they are necessary when the installation is exposed to direct lightning(for example when the buiding is equipped with external lightning protection system or powered by aerial lines).

If you see water leaking out of the bottom of the pool pump assembly, it’s a good indication that you may have to replace the shaft seal within the motor pump assembly. As shown in the pool pump cut away, the shaft seal is located in the motor pump assembly behind the impeller. Although this description is specific to a Hayward pool pump, many of the steps can apply to other models of pool pumps.

The first step is to turn off all power to the pool pump. For maximum safety turn off the power at the circuit breaker to the motor.
Next you will want to remove the motor pump assembly from the wet end housing. Remove the four 9/16″ bolts that bind the motor pump assembly to the housing. Note: some Hayward pool pump models have six bolts. Now pull the assembly apart from the pool pump housing.
After the assembly is out, you should see the pool pump diffuser and diffuser gasket on the end of the assembly. If you do not see the diffuser or its gasket, check inside the housing. If the pool pump diffuser came out with the assembly, pull the diffuser off the assembly. You may have to pry it off gently with a screwdriver. Now you will see the pool pump impeller. The shaft seal is behind the impeller so you will now have to remove the impeller.To remove the pool pump impeller you will twist the impeller off in a counter clockwise motion. The impeller cannot be freed from the motor shaft without first securing the motor shaft.Move to the other end of the motor shaft in the back of the motor assembly. Take off the two screws that hold the back cover onto the pool pump assembly.You will see the pool pump motor wiring and capacitor. You will have to remove the capacitor to gain access to the end of the motor shaft. Capacitors store power. To avoid a possible shock, lay a screwdriver across the two leads to short out the capacitor. These capacitors sometimes burst when shorted out, so it is a good practice to place a cloth over the capacitor and to wear eye protection.
Now unscrew the single screw that hold the capacitor in place and push it out of the way. No need to disconnect capacitor from leads.
Place a 7/16″ wrench on the flat end of the pool pump motor shaft to secure the shaft from rotating.
At the pool pump impeller end, twist off the impeller, counter clockwise. You may have to use a strap wrench to gently free up the impeller.Now you will see the motor shaft seal. One half on the pool pump impeller and the other half in the seal plate on the shaft.
