Installation

NOTICE: Pump motor is equipped with carbon brushes with a normal operating life of about 300 hours. One extra set of brushes is included. Replacement brushes are available from your dealer. Motor brushes not included in warranty.

Fire hazard. Incorrectly mounted brushes may cause fire. Be sure curve on end of brush matches curve on commutator.

LUBRICATION

Motor is lubricated at factory for life of bearings. Pump seal is water cooled and self lubricating.

PUMP SERVICE

Motor has auto-reset thermal overload. If motor over- heats, overload will cut off power to prevent damage and will reset after motor cools. If overload trips repeat- edly, check pump for cause (low voltage, clogged impeller, etc.).

Hazardous voltage. Can shock, burn, or cause death. Disconnect motor from electrical power before servicing pump.

Always replace both brushes - to avoid fire hazard, never replace just one.

Seal Changing Procedure

Hazardous voltage. Unplug pump before continuing.

1.Unplug the pump from the outlet and remove all piping or hoses from the pump.

2.To avoid breaking the brushes when you remove or replace the motor shaft, remove the motor brushes (see “Brush Changing Procedure”, Page 7, Steps 1 and 2). Put the brushes where they will not get lost or damaged while you proceed.

3.Remove 4 screws from the back of the pump body (Key No. 1, Page 8) and remove the pump body from the motor. Remove the old Square-cut O-Ring (Key No. 4C) from the assembly.

4.Unscrew the impeller (Key No. 4A) from the motor shaft and discard it.

5.Pull the seal plate (Key No. 5) from the motor shaft.

6.Turn the seal plate face down (See Figure 4A) and use a screwdriver or small tube to push the station- ary seal half out of the seal plate (Figure 4B).

7.Place a cardboard washer over the seal face to pro- tect it and use a tube to push the stationary seal half into the seal plate until it seats (Figure 4C). Be sure you don’t scratch or mar the polished face of the seal. Also, keep your hands away from the seal face to keep dirt and grease off of it.

8.Use the cardboard washer and tube to push the rotating half of the seal into the new impeller, pol- ished face out (Figure 4D). Be sure you don’t scratch or mar the polished face of the seal. Also, keep your hands away from the seal face to keep dirt and grease off of it.

9.CAREFULLY slide the seal plate back onto the motor shaft, making sure that you don’t chip or scratch the seal face in the process.

10.Thread the new impeller onto the motor shaft, making sure that you don’t chip or scratch the seal face in the process.

11.Reinstall the motor shaft in the motor.

12.Install the new square-cut O-ring on the seal plate.

13.Bring the impeller/motor assembly up to the pump body and insert the impeller and seal plate into the pump body.
