Installation Information
Preparation Guide
1. Upon receipt of the pump, check the carton for damage. Open the carton and check the pump for concealed damage, such
as cracks, dents, or a broken base. If damage is found, contact the shipper or distributor where the pump was purchased.
2. Inspect the contents of the carton and verify that all parts are included.
See Section 7, Parts List and Exploded View for
details.
NOTE: In Canada, the pump must be located a minimum of three (3) meters (approximately ten (10) feet) from the water
(CSA C22.1).
1. For trouble-free self-priming, install the pump as close to the pool as practical. Consult local codes for minimum distance
between pool and pump.
WARNING: Some Safety Vacuum Release System (SVRS) devices are not compatible with the installation of check valves. If
the pool has an SVRS device, be sure to confirm that it will continue to safely operate if check valves are installed.
2. The piping should be as direct and free from turns or bends as possible, as elbows and others fittings greatly increase
friction losses which reduce the flow of water.
3. Place pump on solid foundation which provides a rigid and vibration-free support so that it is readily accessible for service
and maintenance.
4. Install the pump in a well ventilated location protected from direct sunlight and excessive moisture. (rain, sprinklers, etc.)
5. Protect the pump against flooding and excess moisture, and prevent foreign objects from clogging air circulation around
motor. All motors generate heat that must be removed by providing proper ventilation.
6.
DO NOT
store or use gasoline or other flammable vapors or liquids in the vicinity of this pump.
DO NOT
store pool chemicals
near the pump.
7.
DO NOT
remove any safety alert labels such as
DANGER, WARNING,
or
CAUTION
. Keep safety labels in good condition
and replace any missing or damaged labels.
8. Provide access for future services by leaving a clear area around the pump. Allow plenty of space above the pump to
remove lid and basket for cleaning.
Pump Location
Pipe Sizing
NOTE: All pipe sizes are able to withstand the pressures the pump will deliver, but not necessarily the flow. If the pipe is too
small for the pump, or is elevated above water, the maximum gallons per minute (GPM) may not be delivered. If this happens,
the pump will develop a pocket of air (cavitation) that makes noise. This may shorten the life of the pump.
SUCTION & DISCHARGE:
When the pump is located up to 50 feet from the pool, the recommended minimum pipe size for both the suction and discharge
is 2” on the ES90-II VSP. On the A91-II VSP and E71-II VHV, the minimum pipe size for both suction and discharge is 1.5”.
