6. Check hoses for weak and worn condition before each use, making certain that all connections are secure. 7. Periodically inspect the pump and system components. Perform routine maintenance as required (See Maintenance Section). 8. Provide a means of pressure relief for pumps whose discharge line can be shut-off or obstructed. 9. Personal Safety: a.Wear safety glasses at all times when working with pumps. b.Keep work area clean, uncluttered and properly lighted; replace all unused tools and equipment. c.Keep visitors a safe distance from the work area. Make workshop childproof with padlocks, master switches, and by removing starter keys. 10. When wiring an electrically driven pump such as this, follow all electrical and safety codes, as well as the most recent National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA). Risk of electric shock! Never connect the green (or green and yellow) wire to a live terminal! 11. This equipment is only for use on 120 volt (single-phase) and is equipped with an approved 3-conductor cord and 3-prong, grounding- type plug as shown in Figure 1. Main waste line to sewer or septic tank Three prong grounded outlet equipped with a ground fault interruptor Grounding Blade Figure 1 Where a 2-prong wall receptacle is encountered, it must be replaced with a properly grounded 3-prongreceptacleinstalledin accordance with the NEC and local codes and ordinances. 12. All wiring should be performed by a qualified electrician. 13. It is strongly recommended that this unit is plugged into a Ground Fault Circuit Interrupter (GFCI). Con sult a local electrician for installation and availability. The pump motor is equipped with automatic resetting thermal protector and may restart unexpectedly. Protector tripping is an indication of motor overloading as a result of operating the pump at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, incorrect motor conditions, or a defective motor or pump. 14. This pump is designed to transfer water in cycles. Using this pump in a continuous duty application by ma nipulating the switch to stay on, will effect the performance and the life of the product. 15. Protect electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord. Replace or repair damaged or worn cords immediately. Use wire of adequate size to minimize voltage drop at the motor. 16. Do not handle a pump or pump motor with wet hands or when standing on a wet or damp surface, or in water. 17. Do not hang this product by the carry handle. Sewage pumps should be set firmly on their legs and supported by rigid piping. This eliminates twisting and damage during pump operation. 18. Do not use an extension cord. Do not walk on wet area until all power has been turned off. If the shut-off box is in basement, call the electric company to shut-off service to the house, or call the local fire department for instructions. Remove pump and repair or replace. Failure to follow this warning can result in fatal electrical shock. Installation In any Installation where property damage and/or personal injury might result from an inoperative or leaking pump due to power outages, discharge line blockage or any other reason, use a backup system(s). 1. Thread the discharge pipe or pipe nipple into the discharge connection. 2. If a check valve is used in a solids handling system mount the check valve in a horizontal position or at a 45° angle with the valve pivot on top. In a vertical position, solids will tend to lodge on the valve flapper and can prevent it from opening. 3. Drill a 1/16" hole in the discharge pipe approximately 1" to 2” above the pump discharge when a check valve is used. The hole prevents air locking of the pump at the initial start-up and if it should lose prime.

This gate valve should be a full port valve which will pass 2" solids or as required by state and local codes. This gate valve permits removal of the pump and/or check valve for servicing. 5. A union should be installed between the check valve and the pump so the pump can be removed with least disturbance of the piping. 6. The RPP50 pump has a detachable tether switch with a piggyback plug (see Figure 3A). The length of the tether (distance of cord from ...
