4. Choose a location that will minimize turns in the
piping.
NOTE In Canada, the minimum distance maintained
from the edge of the pool and/or spa as noted
above must be 3 meters (10 feet), as required
by the Canadian Electrical Code (CEC, CSA
C22.1).
5. The pump must be placed on a solid foundation
that will not vibrate.
NOTE: To further reduce the possibility of vibration
noise, bolt the pump to the foundation, or place
it on a rubber mat.
6. The pump foundation must have adequate
drainage to prevent the motor from getting wet.
7. Protect the pump from the rain and sun.
8. Proper ventilation is required for the pump to
operate normally. Motor generated heat must be
removed by adequate air fl ow.
9. 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.
10. If the equipment is under cover, provide adequate
lighting.

discharge is 2.5 inches (64 mm). For lengths greater
than 50 feet increase the pipe size according to "Table 1.
Pipe Sizing for Schedule 40 PVC".

3.1.3 Installation Recommendations

1. To help prevent diffi culty in priming, install the
suction pipe without high points (above inlet of
pump, or inverted "U"s, commonly referred to in
plumbing as "airlocks") that can trap air.
2. For installations of equipment up to 100 feet
(30 m) from the water, refer to "Table 1. Pipe
Sizing for Schedule 40 PVC", For installations
of equipment more than 100 feet (30 m) from
the water, the recommended pipe size must be
increased to the next size.

1½" (38 mm)
2" (51 mm)
2½" (64 mm)
3" (76 mm)
4" (102 mm)
3. The pump comes equipped with unions on both
the suction and discharge ports. This feature
simplifi es installation and service and eliminates
the possibility of leaks at threaded adapters.
