Models RPP50 and RPPCAP50
Installation (Continued)
4.A gate valve should be installed in the system after the check valve. 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 float to clamp) should not be set shorter than
7.When any switch is used, rigid dis- charge 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.
8.RPPCAP50 models are supplied with a “Switch Genius” capacitive water sensor. Orient the pump in the basin so that the “Switch Genius” water sensor is 180° away from the inlet.
Make certain the incoming water stream does not hit the “Switch Genius” surface (See Figure 3B).
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 pur- chased or call
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 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.
5.Submerge the complete pump in a disinfectant solution (10% chlorine bleach solution) for at least one hour before handling the pump.
6.For the RPP50, clean all dirt and deposits from the pump float. Make sure float moves freely after cleaning. For the RPPCAP50 clean “Switch Genius” water sensor surface.
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.
