START-UP AND OPERATION 7.7 PIPING - DISCHARGE To minimize friction losses, make piping one size larger than pump openings. Fittings restrict flow; for best performance use fewest possible fittings. Avoid fittings which could cause an air trap. Pool fittings must conform to International Association of Plumbing and Mechanical Officials (IAPMO) standards. 7.8 PIPING - STRAINER Hazardous pressure. Maximum hydrostatic test pressure is 40 PSI (2.8 bar) water pressure. To avoid explosion hazard, DO NOT test strainer with air pressure. Air pressure in strainer can blow cover off of strainer body, which can cause severe or fatal injury. To avoid breaking pump or putting unnecessary strains on pump or strainer body, support pipe independently of pump/strainer. See section 5.3. Center the strainer cover when installing it (especially when pressure testing). When installing cover, clean O-Ring surface in strainer body and lid surface in contact with O-Ring. 8. Start-Up and Operation 8.1 Prior to Start-Up NOTE - If it is necessary to perform a pressure test, prior to initial use, to ensure pump is functioning properly, then the following criteria should be maintained for this test: 1. Have a professional perform this test. 2. Ensure all pump and system components are sealed properly to prevent leaks. 3. Remove any trapped air in the system by fully opening filter manual air relief valve until a steady stream of water (not air or air and water mix) is discharged from the valve. 4. Allow no more than 40 psi (275 kPa) at a water temperature no higher than 100˚ F (38˚ C). 5. Run pressure test for no longer than 24 hours. Immediately inspect all parts to verify they are intact and functioning properly. If pump is being pressure tested (40 PSI MAXIMUM), be sure pressure has been relieved prior to removing cover. All suction and discharge valves MUST be OPEN, as well as filter air relief valve (if available) on filter, prior to starting the circulating pump system. Failure to do so could result in severe personal injury. 16

START-UP AND OPERATION
7.7
PIPING – DISCHARGE
To minimize friction losses, make piping one size larger than pump openings.
Fittings restrict flow; for best performance use fewest possible fittings.
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association of Plumbing and Mechanical Officials
(IAPMO) standards.
7.8
PIPING - STRAINER
Hazardous pressure. Maximum hydrostatic test pressure is 40 PSI (2.8 bar)
water pressure. To avoid explosion hazard, DO NOT test strainer with air
pressure. Air pressure in strainer can blow cover off of strainer body, which can
cause severe or fatal injury.
To avoid breaking pump or putting unnecessary strains on pump or strainer body, support pipe
independently of pump/strainer. See section 5.3.
Center the strainer cover when installing it (especially when pressure testing).
When installing cover, clean O-Ring surface in strainer body and lid surface in contact with O-Ring.

8.1
Prior to Start-Up
NOTE - If it is necessary to perform a pressure test, prior to initial use, to ensure pump is functioning
properly, then the following criteria should be maintained for this test:
1. Have a professional perform this test.
2.
Ensure all pump and system components are sealed properly to prevent leaks.
3.
Remove any trapped air in the system by fully opening filter manual air relief valve until
a steady stream of water (not air or air and water mix) is discharged from the valve.
4.
Allow no more than 40 psi (275 kPa) at a water temperature no higher than
100˚ F (38˚ C).
5.
Run pressure test for no longer than 24 hours. Immediately inspect all parts to verify they
are intact and functioning properly.
If pump is being pressure tested (40 PSI MAXIMUM), be sure pressure
has been relieved prior to removing cover.
All suction and discharge valves MUST be OPEN, as well as filter air
relief valve (if available) on filter, prior to starting the circulating pump
system. Failure to do so could result in severe personal injury.
