PRIOR TO START-UP
NOTE: It is necessary to perform a pressure test prior to initial use to ensure pump is functioning properly.
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 lter manual air relief valve until a steady stream
of water is discharged.
4. Allow no more than 40 psi (276 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
Fill strainer housing with water to suction pipe level. NEVER OPERATE THE PUMP WITHOUT WATER.
Water acts as a coolant and lubricant for the mechanical shaft seal.
NEVER run pump dry. Running pump dry may damage seals, causing leakage, ooding, and voids
warranty. Fill strainer housing with water before starting motor.
DO NOT add chemicals to pool/spa system directly in front of pump suction. Adding undiluted chemicals
may damage pump and voids warranty.
Before removing strainer cover:
1. STOP PUMP before proceeding.
2. CLOSE VALVES in suction and outlet pipes.
3. RELEASE ALL PRESSURE from pump and piping system using lter manual air relief valve.
WARNING: If pump is being pressure tested (40 PSI MAXIMUM), be sure pressure has been released,
using the lter manual air relief valve, before removing strainer cover.
PRIMING THE PUMP
CAUTION: All suction and discharge valves MUST be OPEN, as well as lter air relief valve (if available)
on lter, when starting the circulating pump system. Failure to do so could result in severe personal injury.
• Release all pressure from lter, pump, and piping system. See lter owner’s manual.
• If water source is higher than the pump, pump will prime itself when suction and outlet valves are opened.
• If water source is lower than the pump, unscrew and remove strainer cover; ll strainer housing with water.
• Clean and lubricate strainer cover O-ring with “Jack’s 327” each time it is removed. Inspect O-ring and
• re-install on strainer cover.
• Replace strainer cover on strainer housing; turn clockwise to tighten cover.
NOTE: Tighten strainer cover by hand only (no wrenches).
Turn on power and wait for pump to prime, which may take up to ve (5) minutes. Priming time will depend
on vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within ve
minutes, stop motor and determine cause. Be sure all suction and discharge valves are open when pump
is running. See Troubleshooting Guide.
NOTE: Wait ve (5) seconds before re-starting pump. Failure to do so may cause reverse rotation of motor
and consequent serious pump damage. Close lter manual air relief valve after pump is primed.
