2 VST Variable Speed Pump Installation and User’s Guide
OPERATING THE PUMP
Follow the steps below to prime the pump for start up:
1. Press Start/Stop to stop the pump. Disconnect the
pump main power supply and communication cable.
2. Close all valves in suction and discharge pipes.
Relieve all pressure from the system.
3. Remove the pump lid and locking ring.
4. Fill the pump strainer pot with water.
5. Reassemble the pump lid and locking ring onto the
strainer basket. The pump is now ready to prime.
6. Open all valves in suction and discharge pipes.
7. Open the filter air relief valve and stand clear of
the filter.
8. Connect power to the pump. Be sure green power
light is on.
9. Press Start/Stop to start the pump. The pump will
enter into priming mode (if enabled) and speed
up to the maximum speed set in the pump menu
settings.
10. When water comes out of the filter air relief valve,
close the valve. The system should now be free of
air and recirculating water to and from the pool
11. Do not allow your pump to run longer than
30 minutes time without developing full flow. If the
pump does not prime, check your priming settings
on the control panel or see the “Troubleshooting”
section on pages 24-25.
Priming Features
The default priming setting is ENABLED.
The pump also allows you to set the following from
the operator control panel:
• Priming speed
• Priming range (1-10)
• Priming delay
Set up instructions on page 15.
Priming the Pump
Prime the pump before starting the pump for the first
time. Remove the lid and fill the basket with water. The
pump basket must be filled with water before initial
start up or after servicing.
DO NOT run the pump dry. If the pump is run dry, the mechanical 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.
This pump is shipped with Priming mode ENABLED. Unless the Priming settings are changed in the menu, be aware
that the pump will speed up to the maximum speed when the pump is powered on for the first time, and the
Start/Stop button is pressed. To change the maximum speed of the pump, refer to page 8.
Before turning the pump ON, be sure the following conditions are met:
1. Open filter 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 filter or other pressurized vessels.
NOTE: Speed 1 is the default filtration speed.
NOTE: When setting up the IntelliFlo
®
2 VST Variable Speed Pump, the user must set the pump’s internal clock and establish
an operation schedule by following the steps in this manual. Please refer to user’s guide sections: ‘Set Time’ (page 8) and ‘Set
Speeds 1-8 in Schedule Mode’ (page 11) to schedule a time to run the pump.

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.
This is a variable speed pump. Typically the
lower speeds are used for filtration and
heating. The higher speeds can be used for spa jets,
water features, and priming.
