PUMP MOUNTING
Install pump on a firm, level base or pad to meet all local and national codes. Fasten pump to base or pad with
screws or bolts to further reduce vibration and stress on pipe or hose joints. The base MUST be solid, level, rigid,
and vibration free.
PUMP INSTALLATION SHOULD
• Allow pump inlet height to be as close to water level as possible for installations.
• Allow use of short, direct intake pipe or hose (to reduce friction losses).
• Allow for gate valves in intake and discharge pipes for installations.
• Be protected from excess moisture and flooding.
• Allow adequate access for servicing pump and plumbing.
• Installation of union fittings in front of the pump intake and between the pump outlet and tank is highly rec-
ommended for use with in ground pools.
NOTE - It is recommended that a minimum length of piping, equivalent to 10 pipe diameters, be used between
the pump suction inlet and any plumbing fittings.
WARNING – Hazardous Pressure. Pumps, filters, and other equipment/ components of a swimming pool filtra-
tion system operate under pressure. Incorrectly installed and/or improperly tested filtration equipment and/or
components may fail resulting in injury and/or property damage.
PLUMBING
Use "Teflon" tape, available at any plumbing or hardware store, to seal threaded connections on molded plastic
components. All plastic fittings must be new or thoroughly cleaned before use. NOTE - Do NOT use Plumber's
Pipe Dope as it may cause cracking of the plastic components. When applying "Teflon" tape to plastic threads,
wrap the entire threaded portion of the male fitting with one to two layers of tape. Wind the tape clockwise as
you face the open end of the fitting, beginning at the end of the fitting. The pump suction and outlet ports have
molded-in thread stops. Do NOT attempt to force hose connector fitting past this stop. It is only necessary to
tighten fittings enough to prevent leakage. Tighten fitting by hand and then use a tool to engage fitting an addi-
tional 1 ½ turns. Use care when using Teflon tape as friction is reduced considerably; Do NOT over-tighten fit-
ting or you may cause damage. If leaks occur, remove fitting, clean off old Teflon tape, re-wrap with one to two
additional layers of Teflon tape, and re-install fitting. See the Trouble Shooting section for additional solutions.
FITTINGS
Different pumps come with different type and size hose or plumbing fittings. Review the Technical Sections in this
Owners / Installation manual to insure you have the correct fitting before starting installation. If your new pump
is replacing an older pump it may be necessary to find specialized plumbing fitting to make the plumbing connec-
tions. Check with your local pool professional store or a well-equipped hardware store to find what you need.
Fittings restrict flow. For better efficiency, use the fewest possible fittings (but at least two suction outlets).
Avoid fittings that could cause an air trap. Use a non-entrapping suction fitting in pool (multiple drains) or dou-
ble suction (skimmer and main drain).
