Introduction
This manual contains information for the proper installation and operation of the Hayward MaxFlo Variable Speed
Pump. The instructions in this manual MUST be followed precisely. Failure to install according to defined instructions
will void warranty.
Installation Instructions
WARNING
–
This product should be installed and serviced only by a qualified professional.
Pump Location
Locate pump as close to pool as practical and run suction lines as direct as possible to reduce friction
loss. Suction lines should have continuous slope upward from lowest point in line. Joints must be tight
(but not over-tightened). Suction line must not be less than 40mm in diameter and must be equal to
or larger in diameter than the discharge line diameter.
Though the pump is designed for outdoor use, it is advised to place pump and filter in the shade to shield them from
continuous direct heat. Select a well-drained area that will not flood when it rains. Do NOT install pump and filter in a
damp or non-ventilated location. Keep motor clean. Pump motors require free circulation of air for cooling.
Pump Mounting
Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base
with screws or bolts to further reduce vibration and stress on pipe joints. The base must be level, rigid, and vibration free.
Pump mount must:
• Allow pump inlet height to be as close to water level as possible.
• Allow use of short, direct suction pipe (to reduce friction losses).
• Allow for valves in suction and discharge piping.
• Be protected from excess moisture and flooding.
• Allow adequate access for servicing pump and piping.
*NOTE:
It is recommended that a minimum length of straight piping (shown as “L” in diagram to the right),
equivalent to 5 pipe size diameters, be used between the pump suction inlet and any plumbing fittings (elbows,
valves, ect).
