TAURUS™ VS Variable Speed Pump Installation and User’s Guide
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. Return line 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. If the water level falls below
the suction line, the pump will draw air through the suction line, 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 Taurus™ VS
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.
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 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.
