PREPARATION BASIC TOOLS AND INSTALLATION MATERIALS NEEDED Pipe Wrenches Hacksaw Screwdriver Check Valve Adjustable Knife Teflon NOTICE: Wrench Depth to water (Continued) Suction Pipe iTee and Plug Tape must not be more than 20'. Sanitary Well Seal 1. Long runs and many fittings increase friction and reduce flow. Locate pump as close to water source as possible: use as few elbows and fittings as possible. 2. Be sure water is clear of sand. Sand will plug the pump and void the warranty. 3.
INSTALLATION 2. To aid priming on driven point installations, install a line check valve as shown in Figure 2. Be sure check valve flow arrow points toward pump. DISCHARGE PIPE SIZES (Continued) sprinkler is shown Do not use application. When the pump is set away from the points of water use, the discharge pipe size should be increased to reduce pressure losses caused by friction. • Up to 100' run: Same size as pump discharge • 100' to 300' run: Increase one pipe size.
ELECTRICAL Connection diagram for dual voltage, single-phase motors. Your dual-voltage motor's terminal board (under the motor end cover) will match one of the diagrams below. Follow that diagram if necessary to convert motor to 115 Volt power. Connect power supply wires to L1 and L2. For 3-phase motors, or if motor does not match these pictures, follow the connection diagram on the motor nameplate. 230 Volt to 115 Volt Conversion, Plug-in Type: Move plug to change voltage.
ELECTRICAL (Continued) wiring diagram on motor nameplate against Figure 6. If the motor wiring diagram does not match the diagrams in Figure 6, follow the diagram on the motor. 3. Disconnect power before servicing motor or pump. If the disconnect switch is out of sight of pump, lock it open and tag it to prevent unexpected power application. 4. Ground the pump permanently using a wire of the same size as that specified in wiring chart (below).
OPERATION PRIMING THE PUMP NOTICE: 'Priming' refers to the pump expelling all air in the system and beginning to move water from its source out into the system. It does not refer only to pouring water into the pump (although pouring water in is usually the first step). NOTICE: NEVER run pump dry. Running pump water in it will damage seals and can melt impeller fuser. To prevent damage, fill pump with water starting. 1. Remove priming plug (Figure without and difbefore 7).
MAINTENANCE Pump and piping need not be disconnected to repair or replace motor or seal (see Figure 12). If motor is replaced, replace the shaft seal (Key No. 6, Page 11). Keep one on hand for future use. 2. If impeller must be replaced, loosen two machine and remove motor canopy (see Figure 14). Be sure to prime pump before starting. NOTICE: Check motor label for lubrication instructions. The mechanical shaft seal in the pump is water lubricated and serf-adjusting.
MAINTENANCE 4. Place pump body half face down on flat surface out stationary half of seal (see Figure 16). (Continued) 9. and tap Hold motor shaft with 7/16" open end wrench on shaft flats (Figure 14, Page 8) and screw impeller onto shaft. Be sure you do not touch capacitor terminals with body or any metal object. Tightening impeller will automatically locate seal in correct position. 10. Remount PUMP diffuser on pump body haft with five screws. REASSEMBLY 1. Clean O-Ring and O-Ring groove. 2.
TROUBLESHOOTING SYMPTOM Motor will not run POSSIBLE CAUSE(S) 1. Disconnectswitch is off 2. Fuse is blown 3. Startingswitchis defective 4. Wires at motorare loose, disconnected, CHART CORRECTIVE ACTION f. Be sure switchis on Replace fuse 3. Replace startingswitch 4. Refer to instructions on wiring. Check and tighten all wiring. 2. or wired incorrectly ['_WARNINGI Capacitor voltage may be hazardous.
