READ AND FOLLOW SAFETY INSTRUCTIONS! ‘MPRA’, ‘MPEA’ & ‘MPE’ SERIES PUMPS WITH TRAP This is the safety alert symbol. When you see this symbol on your system or in this manual, look for one of the following signal words and be alert to the potential for personal injury.
1. Do not connect system to a high pressure or city water system. 2. Use equipment only in a pool or spa installation. 3. Trapped air in system can cause explosion. BE SURE all air is out of system before operating or testing equipment.

POOL PUMP SUCTION REQUIREMENTS Allow pump suction inlet height to be as close to water level as possible. Pump will not lift water more than 10' (3m). Allow use of short, direct suction pipe (To reduce friction losses). Allow for gate valves in suction and discharge piping. Have adequate floor drainage to prevent flooding. Be protected from excess moisture. Allow adequate access for servicing pump and piping. Fire and burn hazard. Modern motors run at high temperatures.
ELECTRICAL Water Velocity The maximum water velocity through the suction fitting or cover for any suction outlet must not exceed 1.5 feet per second unless the outlet complies with the latest ANSI/ASME Specification for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any case, do not exceed the suction fitting’s maximum designed flow rate.
Grounding/Bonding 1. Turn off power. 2. Remove the motor end cover. Install, ground, bond and wire motor according to local or National Electrical Code requirements. Permanently ground motor. Use green ground terminal provided under motor canopy or access plate (See Figure 4); use size and type wire required by code. Connect motor ground terminal to electrical service ground. Bond motor to pool structure. Use a solid copper conductor, size No. 8 AWG (8.4 sq.mm) or larger.

OPERATION Replace trap cover on trap; turn clockwise to tighten cover. NOTICE: Tighten trap cover handle ring by hand only (no wrenches)! See Figure 1, Page 4. Pump should prime now. Priming time will depend on vertical length of suction lift and horizontal length of suction piping. If pump does not prime, make sure that all valves are open, suction pipe end is under water, pump is not trying to lift water more than 10' (3m), and that there are no leaks in suction pipe. See Troubleshooting Guide, Page 12.
For outdoor/unprotected installations: Startup For Winterized Equipment 1. Enclose entire system in a weatherproof enclosure. 1. Remove any temporary weather protection placed around system for shutdown. 2. To avoid condensation/corrosion damage, allow ventilation; do not wrap system in plastic. 2. Follow filter manufacturer’s instructions for reactivation of the filter. 3. Use a 40% propylene glycol/60% water solution to protect pump to -50°F (-46°C). 3.
Pump Reassembly/Installing New Seal If shaft seal is worn or damaged, repair as follows: 1. Ceramic seat must be clean and free of dirt, grease, dust, etc. Wet outer edge with small amount of liquid detergent; press ceramic seat into seal plate cavity firmly and squarely with finger pressure (Figure 7). Pump Dissasembly/Removing Old Seal Disconnect power to pump motor. Be sure valves on suction and return piping are closed before starting work.
Electrical: 10. Pump may be running too slowly; check voltage at motor terminals and at meter while pump is running. If low, see wiring instructions or consult power company. Check for loose connections. 11. Pump may be too hot. A. Check line voltage; if Hazardous voltage. less than 90% or more Can shock, burn, than 110% of rated or cause death. voltage consult a Disconnect power licensed electrician. before working B.
