Priming
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 priming speed when the pump is powered on for the first
time, and the start/stop button is pressed.
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.
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.
Priming will automatically run when the VS2 Variable
Speed Pump is started from a stopped state, except when
running in Quick Clean mode. Priming will run at 2850
RPM by default, and will last for 5 minutes. The drive's
screen will display and cycle through the following things
"PrI - Priming Speed, PrI -- Remaining Time".
Once priming has begun, the speed can be adjusted
between 3450 and 1700 RPM using the "+" and "-" arrows.
If it is adjusted below 1700 RPM, Priming mode will be
disabled and the pump will immediately begin to run the
scheduled speed.
When priming is disabled and the pump is started from a
stopped state, the screen will display, "PrI - OFF" for 10
seconds while running the scheduled speed (See Figure
11). This allows the user time to enable priming mode by
pressing the "+" arrow. If the user chooses to re-enable
priming mode, the pump will then transition from the
scheduled speed to 1700 RPM. The user can increase
the priming speed from 1700 RPM by pressing the "+"
arrow. The 5 minute priming countdown timer starts when
priming is first engaged.

The installer should set the priming speed to be sufficient for
priming the pump from a fresh install, but not so fast that
there is a substantial waste of energy during the 5 minute
priming window. The time the pump needs to achieve
prime can change based on local environmental conditions
such as water temperature, atmospheric pressure, and your
pool's water level. All of these things should be taken into
consideration when setting the priming speed, however in
most cases the pump will not need to run at 2850 RPM to
successfully prime itself.
Please test and verify chosen priming speeds more than
once, letting the water drain from the system in between
each test.
Note: The pump strainer basket should always remain full to
the bottom of the inlet in order to prevent air from entering
the system.
