The water inside the pump could boil and damage the pump. Maintenance Maintain adequate ventilation for the pump motor. The motor bearings are permanently lubricated at the factory. Additional lubrication is not required. DRAINING FOR WINTER Always protect pump and piping against freezing temperatures. If there is any danger of freezing, drain the system. To drain the system: 1. Remove the pipe plug from the discharge tee. 2. Remove the 1/4” plug from the lower front face of the pump. 3. Drain all piping below the frost line.

Disconnect switch is off 2. Fuse is blown 3. Starting switch is defective 4. Wires at motor are loose, disconnected or wired incorrectly 1. Be sure switch is on 2. Replace fuse 3. Replace starting switch 4. Refer to wiring instructions. Check and tighten all wiring Capacitor voltage may be hazardous. To discharge capacitor, touch short capacitor terminals with an insulated screwdriver. BE SURE to hold handle of screwdriver while making contact with capacitor terminals. Motor runs hot and 1. Motor is wired incorrectly 1. Refer to wiring instructions overload kicks off 2. Voltage is too low 2. Check with power company. Install heavier wiring if wire size is too small (See wiring chart) 3. Pump house not properly vented 3. Be sure pump has sufficient ventilation to cool the motor Motor runs but no water is delivered Note: Check prime before looking for other causes. Unscrew priming plug and see if water is in priming hole. 1. Pump in new installation did not pick up prime through: a. Improper priming b. Air leaks c. Leaking foot valve 2. Pump has lost prime through: a. air leaks b. water level below suction of pump 3. Impeller is plugged 4. Check valve or foot valve is stuck in closed position 5. Pipes are frozen 6. Foot valve and/or strainer are buried in sand or mud 1. New installation: a. Re-prime according to instructions b. Check all connections on suction line c. Replace foot valve 2. Existing installations: a. Check all connections on suction line and shaft seal b. Lower suction line into water and re-prime. If receding water level in well exceeds suction lift, a deep well pump is needed 3. Clean impeller 4. Replace check valve or foot valve 5. Thaw pipes. Bury pipe below frost line. Heat pit or pump house 6. Raise foot valve and/or stainer above well bottom Pump does not 1. Water level in well is lower than 1. A deep well jet pump my be needed (over 25 ft. (7.6M) to deliver water to full estimated water) capacity 2. Steel piping (if used) is corroded 2. Replace with plastic pipe where possible, otherwise with new or limed, causing excess friction steel pipe 3. Piping is too small in size 3.
