Section 3. Installation Information

3.1

Zero Clearance TEFC Motor

The Jandy pumps in this manual feature a Zero
Clearance Totally Enclosed Fan Cooled (TEFC) motor.
Unlike most TEFC motors which draw in cool air from
the back of the fan shroud and require 2"-3" of clearance,
the Jandy Zero Clearance TEFC motor pulls in air from
the top, bottom and sides of the fan shroud. The Zero
Clearance TEFC motor makes it possible to install the
pump with minimal clearance between the back of the
fan shroud and potential obstructions such as a fence or
foundation. Clearance must still be provided on the sides
of the motor and fan shroud to allow for adequate air-
flow and maintenance of the pump.

Plumbing

3.2.1 Preparation Information
1. Check the pump carton for any damage. If any
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.
3.2.2 Pump Location
Zodiac Pool Systems LLC recommends installing the
pump within one foot (30 cm) above water level. The
pump should not be elevated more than 5 feet (152 cm).
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
A check valve can interfere with the proper operation
of certain Suction Vacuum Release System (SVRS)
products. To avoid possible entrapment hazard, serious
injury, or death, make sure to review the operation/
owners manual of your particular SVRS product before
installing the check valve.
WARNING
To Reduce the Risk of Fire, install pool equipment in
an area where debris will not collect on or around the
equipment. Keep surrounding area clear of all debris
such as paper, leaves, pine needles and other
combustible materials.
In order to avoid premature failure or damage to
the pump motor, protect the pump from direct water
exposure from sprinklers, water runoff from rooftops and
drainage, etc. Failure to comply may cause pump failure,
and may void the warranty.

Installation & Operation Manual
CAUTION
ENGLISH
NOTE:
When the pool equipment is located
below the pool surface a leak can result in large
scale water loss or flooding. Zodiac Pool Systems
LLC cannot be responsible for such water loss or
flooding or damage caused by either occurrence.
1. Install the pump such that any disconnecting
means and/or junction boxes for power connection
are within sight of the pump and at least five feet
horizontally from the edge of the pool and/or spa.
Choose a location that will minimize pipe turns.
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).
2. Place the pump on a solid foundation that will
not vibrate. To further reduce the possibility of
vibration noise, bolt the pump to the foundation.
3. Assure that the foundation has adequate drainage
to prevent the pump motor from getting wet. The
pump needs to be protected from the rain and sun.
4. Make sure the pump has the proper ventilation to
prevent the motor from overheating.
5. Allow plenty of space for any maintenances by
leaving a clear area around the pump.
6. Provide adequate lighting if the equipment is in a
potentially dark area.

3.2.3 Installation Recommendations
1. To help prevent difficulty in priming, install the
suction pipe without high points (above inlet
of pump - inverted "U"s, commonly referred to
in plumbing as an airlock) that can trap air. For
installations of equipment up to 100 feet (30 m)
from the water, refer to Table 1, the pipe sizing
chart. For installations of equipment more than 100
feet (30 m) from the water, the recommended pipe
size must be increased to the next size.
