Prime the pump before starting the pump for the rst time. To
avoid permanent damage to the pump, remove the lid and ll the
strained pot up to the suction port with water. The strainer pot
must be lled with water before initial start-up or after servicing.
TO PRIME THE PUMP:
1. Press Start/Stop to stop the pump and disconnect all power
to the pump at the circuit breaker.
2. Close all valves in suction and discharge pipes.
3. Relieve all pressure from the ltration system at the lter air
relief valve.
4. Turn the strainer pot lid counter-clockwise and remove it
from the pump. See Figure 12.
5. Fill the strainer pot up to the suction port with water.
6. Place the lid onto the strainer pot and tighten clockwise until
the lid handles are horizontal.
Note: Ensure the lid O-ring is properly placed and is not
being pinched between the lid and strainer pot.
7. Open all valves in suction and discharge pipes.
8. Open the lter air relief valve and stand clear of the lter.
9. Reestablish power to the pump and ensure green power
light is on.
10. Press Start/Stop to start the pump. The pump will begin to
prime (if enabled) and ramp up to the programmed priming
speed.
11. When a steady stream of water comes out of the lter air
relief valve, close the valve.
12. The pump will prime for 5 minutes.
Note: Do not allow the pump to run longer than 30 minutes
before succesfully priming. If the pump does not prime,
check your priming speed (see Priming Adjustment on
page 11) or refer to the TROUBLESHOOTING on page
20.
Priming the Pump
This pump is shipped with Priming mode ENABLED. Unless the Priming Speed has been modied, the pump will ramp up to 3450
RPM when powered on for the rst time, and the Start/Stop button is pressed.
Before turning the pump ON, be sure the following conditions are met:
1. Open lter air relief valve.
2. Open valves.
3. Pool return is completely open and clear of any blockages.
4. Water in the pump basket.
5. Stand clear of the lter or other pressurized vessels.
DO NOT run the pump dry. If the pump is run dry, the shaft seal will be damaged and the pump will start leaking. If this occurs, the
damaged seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If the water level
falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal.
Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal and may cause property and
personal injury.
Do not add chemicals to the system
directly in front of pump suction. Adding
undiluted chemicals may damage the pump and will void the
warranty.
