Check valve 45. Vent Inlet Gasket 1/2 inch Min. Clearance Basin Figure 3 - Prefabricated Basins 7. When a tether switch is used, rigid discharge pipe is required. If the pump is allowed to move, the tether switch could be restricted by the basin wall, preventing the pump from operating. Before removing pump from basin for service, always disconnect electrical power to pump and control switch. For any work on pump or switch, ALWAYS unplug the power cord. Do not just turn off circuit breaker or unscrew fuse. Maintenance Make certain that the pump is unplugged before attempting to service or remove any component. This pump is assembled in the factory using special equipment; therefore only authorized service dealers or qualified electricians should attempt to repair this unit. Improper repair can cause an electrical shock hazard. The pump contains oil that may be under pressure because of heat. Let the pump cool for a minimum of two hours before servicing this unit. 1. Disassembly of the motor prior to expiration of warranty will void the warranty. It might also cause internal leakage and damage to the unit. If repairs are required, return the pump to the dealer from whom it was purchased or call 1-800-2370987. If motor is ever disassembled the o-rings must be replaced. Care must be taken to ensure that all seals do not leak. 2. After the basin cover is removed and necessary discharge piping disconnected, lift pump from basin. 3. Pump should be checked on a regular basis for proper operation. If anything has changed since unit was new, the unit should be removed and repaired or replaced. Only qualified electricians or service people should attempt to repair this unit. Improper repair and/or assembly can cause an electrical shock hazard. 4. Place the pump in a suitable area where it can be cleaned thoroughly. Remove all scale and deposits on pump. 3 Operating Instructions and Parts Manual Maintenance (Continued) 5. Submerge the complete pump in a disinfectant solution (10% chlorine bleach solution) for at least one hour before handling the pump. 6. Clean all dirt and deposits from the pump float. Make sure float moves freely after cleaning. 7. Clean all dirt and deposits away from pump inlet and volute. This pump contains dielectric motor oil for lubrication and motor heat transfer. This oil can be harmful to the environment. Check state environmental laws before disposing of this oil. This oil can be harmful to aquatic life so consideration should be exercised in the application of this pump. troubleshooting Chart Symptom Possible Cause(s) Corrective Action Pump will not start 1. Water level too low or run 2. Blown fuse or tripped circuit breaker 3. Low line voltage 4. Defective motor 5. Defective float switch 6. Impeller (pump filled with debris) 7. Tangled switch 8. Insufficient liquid level 1. Pump switch will not turn on unless water covers top of pump 2. If blown, replace with proper sized fuse or reset breaker 3. If voltage is under recommended minimum, check wiring size from the main switch on property. If OK, contact power company. 4. Return for service or replace motor 5. Replace float switch 6. If impeller will not turn, remove housing and remove debris 7. Arrange switch so the switch moves freely. Reposition pump if necessary 8. Make sure liquid level is at least 13 inches from the basin floor Pump starts and 1. Backflow of water from piping 1. Install check valve stops too often 2. Faulty float switch 2.
