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 SuperMax
Variable Speed Pump is started from a stopped state,
except when running in Quick Clean mode. Priming will
run at 3450 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 10). 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.

Figure 10: Priming Deactivation
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 3450 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.
