Installation - STA-RITE Max-E-Pro Series Installation And User Manual

Trapped air in the system can cause permanent equipment damage. Ensure all air is relieved from the system before operating, testing or
servicing the equipment.
Do NOT connect system to a high pressure or city water system.
Location
Only qualified, licensed personnel should install the pump
and pump wiring.
Be sure the Max-E-Pro Pool and Spa Pump equipment
®
pad or plumbing meets the following requirements:
•
Pump mount must be solid, level, rigid and minimize
vibration. To reduce vibration and stress to piping,
bolt the pump to the equipment pad.
•
Allow for enough ventilation to maintain air
temperature at less than the maximum ambient
temperature rating listed on the motor nameplate.
•
If installed in an enclosure/pump house, the
enclosure must have adequate ventilation and
air circulation to keep the temperature inside the
enclosure at or below the maximum rated ambient
temperature when the pump is running.
•
Locate away from corrosive or flammable liquids.
•
Suction port should be as close to water level as
possible.
•
To reduce friction losses use short, straight suction
pipe.
•
Allow for gate valves in both the suction and
discharge piping.
•
Provide adequate floor drainage to prevent flooding
and protect the pump from excess moisture.
•
Allow adequate access for servicing pump and
piping.

Piping
1.
Use at least 2" (51mm) pipe. Increase size if a long run is needed.
2. Support both the suction and discharge piping independently,
placing these supports as close to the pump as possible. This will
prevent unnecessary strain on the pump.
3.
During piping installation, start all piping and run the pipe away
from the pump. This will prevent strain caused by a gap at the last
connection.
4.
Slope suction pipe slightly upward toward the pump to prevent
airlocking.
5.
To prevent flooding when removing the pump for service, all
flooded suction systems must have a gate valve in both the
suction and discharge pipes.
6.
For most installations Pentair recommends installing a valve
on both the pump suction and return lines so that the pump
can be isolated during routine maintenance. However, we also
recommend a valve, elbow or tee installed in the suction line
should be no closer to the front of the pump than five (5) times
the suction line diameter.
Example: A 2 inch pipe requires a 10 inch (25.4 cm) straight run
in front of the suction inlet of the pump. This will help the pump
prime faster and last longer.
Note: Do not install 90° elbows directly into the pump inlet or
outlet.
Taping Instructions
1.
If connecting threaded pipe directly to the pump, apply one or
two layers of thread seal tape to the male pipe threads. Cover the
entire threaded portion of the pipe.
Note: Do NOT use pipe dope; pipe dope can lead to cracking in
some plastics and may damage components in the piping system.
2.
If plumbing threaded pipe to the pump using unions, apply thread
seal tape between the pipe and union adapter. The union collar
should be installed hand-tight. Be sure the union's O-ring is
seated correctly in its groove.
Note: DO NOT overtighten or tighten past the thread stops within
the pump ports.
If leaks occur, remove pipe, clean off old tape, rewrap with one or two
layers of new tape and reinstall the piping.
Fittings
1.
Fittings restrict flow. Use the fewest number of fittings possible to
maximize system efficiency.
2.
Avoid fittings that could lead to air traps in suction piping.
3. Pool and spa drains must conform to International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
4. Use only non-entrapping suction fittings and dual suction outlets.
