Pump Installation

Pump Servicing

Read the following instructions carefully before replacing any parts. Reasonable care and safe methods should be practiced. Check local codes and requirements before installation. Only com pe tent electricians should make the installations.
Servicing should be performed only by knowledgeable pump service contractors or authorized service stations.
WARNING : Always disconnect the pump from the power source before handling or making any adjustments. Always wear rubber boots when there is water on the floor and you must unplug the pump or make any ad just ments.

1. Removing the pump from the sump. Before removing the pump from the sump for repair, check to see if the trouble could simply be a blown fuse, tripped circuit breaker, or a power cord not completely inserted into the receptacle.
   NOTE : Automatic thermal overload protects the sealed-in oil motor. Running dry may overheat the motor and activate the overload protector. This will close the circuit when the motor cools and allow the pump to restart. If the condition continues to exist, it may cause premature pump failure.
   Unplug the power cord and pull the pump, by the handle, from the sump. Sandblast, if possible, any dirt or trash from the outside of the pump before dismantling.

2. Check the diaphragm switch. If the unit is being operated by the automatic diaphragm switch, unplug the pump from the pig gy back receptacle and plug the pump directly into the power source. If the pump starts each time it is plugged directly into the receptacle and does not start each time when plugged into the piggyback switch with the diaphragm switch pressed into a start position, replace the complete piggyback switch assembly and retest with the new assembly.

3. Check for impeller blockage. Check for an obstruction in the impeller cavity by laying the pump on its side and inserting a screwdriver through the hole in the foot and baffle plate
   (28) and the bottom plate (26) and turning the rotor and shaft (16). It should turn freely. If the impeller hangs up or there is an indication of the impeller blockage, the foot, and baffle plate must be removed by removing the three hex head cap screws (29) and the bottom plate removed by removing the five hex head cap screws (27). Clear the impeller of its obstruction and clean the impeller, and reassemble it.

4. Check the power cord. Check the power cord (5) for brittleness or for any cuts or nicks in the insulation. Using an ohmmeter, check the continuity of the power cord. If any of these tests fail, the power cord should be replaced. To replace the power cord, unscrew the nut on the cord, pull the cord up and discard the damaged power cord. Add pipe sealant to threads and reinstall by pushing the cord onto pins and tightening the nut.

5. Check for airlock. A sump pump is said to be air locked if water traps in the pump and it cannot get out, thus preventing the pump from operating. Hydromatic pumps have a small air vent hole in the impeller cavity to let out trapped air. If this hole becomes plugged, the pump may airlock. To break the air lock, use a small screw-driver to clear hole in the impeller cavity. As a secondary precaution in installations of this type — 1⁄16″ hole should be drilled in the discharge pipe below the check valve. The check valve should be 12 to 18 inches above the pump discharge. Do not put the check valve directly into the pump discharge opening.
   NOTE : In sumps where the pump is operating daily, air locking rarely occurs.

6. Check the oil. Remove the pipe plug (4) in the top of the motor cover and drain oil into a clean, dry container. A milky appearance to the oil indicates that water has entered through either worn out or damaged seals (23, 24), seal rings (20), or cord nut.

7. Remove the motor cover. Remove the four hex head cap screws (22). Use a screwdriver to pry the motor cover (19) from the volute case (21) at the fastening ears, being careful not to cut the seal ring (20) with the screwdriver or crack the motor cover. Lift the motor cover until it clears the stator (15).

8. Check for short. Disconnect the stator leads (7, 8, 9) from the connector (6). Use an ohmmeter to check the continuity of the stator. If stator fails to pass the continuity test, it must be replaced.

9. Remove the stator. To remove the stator, remove the four hex head screws (12) and the stator plate (13). Lift the stator off the volute case (21) and set aside.

10. Remove the impeller. To remove the impeller (25), hold the rotor (16) in your hand and tap the impeller with a plastic or rubber mallet so as to turn the impeller counterclockwise.

11. Check the seal. Remove the rotating portion of the seal (24) from the shaft by inserting a screwdriver under the edge of the seal and lifting it off without damaging seal. Inspect the seal face for any nicks or uneven seating of the seal face. If any are present, replace the seal.

12. Remove the rotor and shaft. Tap the rotor shaft (16) at the impeller end of the shaft with a plastic mallet to remove the rotor and shaft. Inspect the bearings (17). If they do not rotate freely and smoothly, they should be replaced. When new bearings are ready to be added onto the shaft, do not push on outer face of the bearings. This will damage bearings. If a rotor and shaft are ordered from HYDROMATIC, the bearings will be supplied already pressed on the shaft.

13. Remove seal. Remove the old stationary portion of the seal (23) from the case (21) by inserting a screwdriver into the seal housing of the case from the top of the case and tapping lightly with a hammer. Clean the seal area of the case with a clean cloth.

14. Reinstall the rotor and shaft assembly. Push on the outer face to the seat bearing in a volute case.

15. Reinstall seal. Apply an oil lubricant to the new stationary portion of the seal (23) and press it into the case (21). Coat the new rotating portion of the seal with lubricant and press it into place on the rotor shaft with the rubber ring facing the impeller.

16. Reinstall impeller. Add a drop of Locktite 277 to the shaft and screw the impeller on hand tight. The impeller will force the rotating portion of the seal into position.

17. Replace the seal ring. Remove the old square seal ring (20) from the volute and stretch on a new ring coated with O-ring lube.
    Do not roll the ring onto the volute or improper seating and water leakage into the motor housing will result.

18. Reinstall the stator. Place the stator (15) in the volute case (21) so the stator bolt holes line up. Lay the stator plate (13) on the stator (15) and line up with stator bolt holes. Put in the stator bolts (12) and tighten them evenly to prevent cocking of the stator. Push the connectors of the power cord onto the stator terminals.

19. Reinstall motor housing. Tighten down the four hex head cap screws (22) evenly to prevent cocking of the motor housing and achieving an uneven seal on the seal ring (20).

20. Oil. Fill the motor cap with high-grade transformer oil such as WOCO Premium 100 oil or equivalent to at least 1⁄4″ over motor windings (.54 gallon).
    Do not fill the motor housing completely — allow airspace for oil expansion.

21. Reinstall oil pipe plug. Coat pipe threads with thread sealant before installing.

22. Check pump. Plug the power cord into a grounded outlet and start the pump by applying pressure to the switch diaphragm (automatic only —manual should start when power is applied). The motor should run smoothly, be free of vibration and stop when pressure is removed.
