Installation and Operation Manual
Section 3. Installation
3.1 Plumbing
3.1.1 Preparation
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
bent base. If you find damage, contact the shipper
or the distributor where the pump was purchased.
2. Inspect the contents of the carton and verify
that all parts are included. See Section 7.1,
Replacement Parts List.
3.1.2 Pump Location
1. Zodiac Pool Systems, Inc. recommends installing
the pump within 1 foot above water level. The
pump should not be elevated more than a few
feet above the water level of the pool. A check
valve is recommended on the suction line to the
pump.
NOTE
Better self-priming will be achieved if the pump is
installed as close as possible to the water level of the
pool.
2. If the pump is located below water level,
isolation valves must be installed on both the
suction and return lines to prevent back flow
of pool water during any routine or required
servicing.
WARNING
Some Safety Vacuum Release System (SVRS)
devices are not compatible with installation of check
valves. If the pool has an SVRS device, be sure to
confirm that that it will continue to safely operate when
any check valves are installed.
3. Zodiac Pool Systems, Inc. recommends that
the pump and other circulation equipment be
located more than 5 feet from the water. Choose
a location that will minimize turns in the piping.
NOTE
In Canada, the pump must be located a minimum of
3 meters (approximately 10 feet) from the water (CSA
C22.1).
4. The pump must be placed on a solid foundation
that will not vibrate. To further reduce the
possibility of vibration noise, bolt the pump to
the foundation, or place it on a rubber mat.
NOTE
Zodiac Pool Systems, Inc. recommends bolting the
pump directly to the foundation.
5. The pump foundation must have adequate
drainage to prevent the motor from getting wet.
Protect the pump from the rain and sun.
6. Proper ventilation is required for the pump to
operate normally. All motors generate heat that
must be removed by providing proper ventilation.
7. Provide access for future service by leaving a
clear area around the pump. Allow plenty of
space above the pump to remove the lid and
basket for cleaning.
8. If the equipment is under cover, provide adequate
lighting.
3.1.3 Pipe Sizing
3.1.3.1 Suction Pipe
When the pump is located up to 50 feet from the pool, the
recommended
Schedule 40
minimum pipe size for the
suction side of the pump is 2" for 1 to 2 HP. For 2.5 HP
pumps, the recommended pipe size is 2½".
3.1.3.2 Discharge Pipe
When the pump is located up to 50 feet from the pool,
the recommended Schedule 40 minimum pipe size for the
discharge side of the pump is 2" for 1 to 2 HP. For 2.5 HP
pumps, the recommended pipe size is 2½".
NOTE
All pipe sizes (Schedule 40) 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 if
the pump is elevated above water, the maximum
gallons per minute (GPM) may not be delivered. If
this happens, the pump will develop an air pocket
(cavitation) that will make noise, and the life of the
pump might be shortened.
3.1.3.3 Installation Recommendations
1. If the pump is located below water level,
isolation valves must be installed on both sides
of the pump to prevent back flow of pool water
during any routine or required servicing.
2. To help prevent difficulty in priming, install the
suction pipe without high points (above inlet of
pump - inverted “U”s in plumbing commonly
referred to as an airlock), which can trap air. For
installations of equipment up to 100 feet from the
water, refer to the pipe sizing chart in Table 1.
For installations of equipment more than 100 feet
from the water, the recommended pipe size must
be increased to the next size.
