Installation - Pentair MAX Series Instruction Manual

CHAPTER 3
INSTALLATION (SEE FIG. 1)
DANGER - ELECTRIC SHOCK RISK
When installing, please ensure electropump is disconnected from electrical supply. Pumps in this series are not
suitable for use in a swimming pool and the relevant cleaning and servicing operations.
WARNING
Protect the electropump and all pipes from bad weather or freezing conditions.
DANGER
To prevent possible injuries to people, avoid inserting hands into the mouth of the pump if this is connected to
the mains.
Use a suction pump (2) with a diameter
•
equivalent to that of the suction mouth
of the electropump (1)
• If the height (HA) is over 4 meters use a
tube with a larger diameter
The suction line should be perfectly
•
airtight
• No elbows and/or slopes should be
present to prevent the formation
of air locks that could affect the
electropump efficiency
• A foot valve (3) with filter (4) should be
fitted at about half a metre below the
fluid that has to be pumped (HI) on one
end of the line
ATTENTION
Connection, suction and delivery pipes should be connected with the utmost care. Make sure that all connections fixed by means of
screws are sealed. Avoid applying excessive stress to tighten the screws of connections or of other components.
Use a Teflon tape to completely seal all joints.
To use the pump in continuous mode for swimming pools, garden ponds and in similar installations, it is necessary to fix the
electropump to a stable support. Mobile electropumps can be used for swimming pools, garden ponds or similar installations, only if no
people is contact with water or if the electric system has a safety cut-out switch.
The pump should be fitted in a stable position in order to avoid falls and protect it from inundation.
Contact a specialised electrician.
If installed for use with drinking water, clean the pump prior to installation - also clean if left unused for prolonged periods of time.
For drinking water, all materials used upstream and downstream of the pump must also be suitable for contact with drinking water for
human consumption.
Load losses can be reduced using
•
delivery piping with a diameter
equivalent or greater than the
electropump mouth (5)
It is advisable to install a check
•
valve (6) directly on the delivery line
to prevent the electropump being
damaged by "water hammer"
• A cut-off valve (7) should also be
installed downstream from the check
valve, to facilitate servicing operations
• Piping should be fitted so that
vibrations, when existing, tension and
weight do not affect the pump
Piping should be routed along the
•
shortest and straighter track, avoiding
an excessive number of bends
• Verify that the motor is properly
ventilated
For permanent installations, it is
•
advisable to fix the electropump to the
supporting base, connect the system
with a section of non flexible pipe and
insert a layer of rubber (or another
anti-vibration material) between the
supporting base and the pump, in
order to reduce vibrations
The site of installation must be stable
•
and dry to guarantee the stability of
the pump
