Read all servicing instructions before working on the pump. WARNING — DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water in the strainer pot. Pumps operated in these circumstances may experience a build up of vapor pressure and may contain scalding hot water. Opening the pump may cause serious personal injury. In order to avoid the possibility of personal injury, make sure the suction and discharge valves are open and strainer pot temperature is cool to touch, then open with extreme caution. Pump Disassembly 1. All moving parts are located in the rear sub-assembly of this pump. Tools required: a. 1/4 inch socket or open end wrench. b. 3/8 inch socket or open end wrench. c. 9/16 inch open end wrench. d. Flat blade screwdriver. 2. To remove and repair the motor sub-assembly perform the following procedures: a. Turn off the pump circuit breaker at the main panel. b. Drain the pump by removing the drain plugs. c. Remove the 4 bolts that hold the main pump body (strainer pot/volute) to the rear sub-assembly. d. GENTLY pull the two pump halves apart, removing the rear sub-assembly. e. Remove the three hex head screws holding the diffuser in position. CAUTION — Be sure not to scratch or mar the polished shaft seal faces; seal will leak if faces are damaged. f. Hold the impeller securely in place and remove the impeller lock screw by using a flat blade screwdriver or wrench. The screw is a left-handed thread and loosens in a clockwise direction. g. Remove the shaft cap located at the back of the motor and hold the shaft secure with a . inch (Century®) or 7/16 inch (Franklin) open-end wrench. On A. O. Smith motors, remove the motor canopy, move the capacitor to one side and hold the shaft with a 7/16 inch open-end wrench. SuperMax™ Pump Installation and User’s Guide Pump Disassembly, cont’d. h. To unscrew the impeller from the shaft, twist the impeller counter-clockwise. i. Remove the four bolts from the seal plate to the motor using a 3/8 inch wrench. j. Place the seal plate face down on a flat surface and tap out the ceramic seal. k. Clean the seal plate, seal housing, and the motor shaft. Pump Reassembly/Seal Replacement; see Section 7, Technical Data, and Figure 5 1. When installing the replacement seal into the seal plate, use soapy water to wet the rubber boot before pressing it into the seal plate. 2. Remount the seal plate to the motor. 3. Before installing the rotating portion of the seal on the motor shaft, wet the motor shaft with soapy water and slide the seal onto the motor shaft. Ensure that the carbon face contacts the ceramic face of the stationary seat. Press the seal into the seal plate with your thumbs and wipe off the ceramic with a clean cloth. 4. Grease the motor shaft thread and screw impeller onto the motor shaft. 5. Screw in the impeller lock screw (counterclockwise to tighten). 6. Remount the diffuser onto the seal plate. Make sure the plastic pins and holding screw inserts are aligned. 7. Grease the diffuser quad ring and seal plate o-ring prior to reassembly. 8. Grease the bolt threads, assemble the motor sub-assembly to the strainer pot-pump body by using the two through bolts for proper alignment. Do not tighten the through bolts until all 4 bolts are in place and finger tightened. 9. Fill the pump with water. 10. Reinstall the pump lid and plastic clamp; see SECTION 3, Maintenance. 11. Reprime the system. The Shaft Seal 1. The Shaft Seal consists primarily of two parts, a rotating member and a ceramic seal. 2. The pump requires little or no service other than reasonable care, however, a Shaft Seal may occasionally become damaged and must be replaced. CAUTION — The polished and lapped faces of the seal could be damaged if not handled with care. CAUTION — In mild climate area, when temporary freezing conditions may occur, run your filtering equipment all night to prevent freezing.

SuperMax™ Pump Installation and User’s Guide Section 5 Restart Instructions If the SuperMax™ pump is installed below the water level of the pool, close return and suction lines prior to opening hair and lint pot on pump. Make sure to reopen valves prior to operating. CAUTION — DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal. NOTE Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal. Priming the Pump 1. The pump strainer pot must be filled with water before the pump is initially started. Follow these steps t...
