FIGURE 1 INSTALLATION Only qualified, licensed personnel should install pump and wiring. Pump mount must: Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress, bolt pump to mount.) Allow pump suction inlet height to be as close to water level as possible. Allow use of short, direct suction pipe (To reduce friction losses). - Page 5 Piping: Use at least 1-1/2" IPS PVC pipe with 5” trap. Use at least 2” pipe with 6” trap. Increase size if a long run is needed. To avoid strains on the pump, support both suction and discharge pipes independently. Place these supports near the pump. To avoid a strain left by a gap at the last connection, start all piping at the pump and run pipe away from the pump.
- Page 6 Suction Outlets Per Pump Provide at least two hydraulically balanced main drains, with covers (see Page 5), as suction outlets for each circulating pump suction line. The cen- ters of the main drains (suction outlets) on any one line must be at least three feet apart.
