VS and SUPERMAX® VS Variable Speed Pumps Installation and User’s Guide
11
This pump is shipped with Priming mode ENABLED. The pump will ramp up to 3450 RPM when the pump is initially started.
Before turning the pump ON:
1. Open lter air relief valve.
2. Open necessary valves.
3. Ensure return line is completely open and clear of any blockages.
4. Ensure pump is lled with water.
5. Stand clear of the lter or other pressurized vessels.
DO NOT run the pump 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 body, impeller and seal and
may cause property and personal injury.
Priming
Priming will automatically run when the pump is
started, except when running a Quick Clean cycle.
Default Priming Speed is 3450 RPM, and will last for 5
minutes. The drive will display and cycle through “Prl
-- Priming Speed, Prl -- Remaining Time”.
If externally controlling the pump via an RS-485
connection and priming is enabled at both the
pump and control system: Both priming timers will
start simultaneously, but the pump priming settings will
have priority over the control system's.
Note: After the pump's priming cycle has
completed, if there is time remaining on the
control system's priming timer the pump will
run the control system priming speed until
the timer expires.
During the priming sequence, priming speed
can be adjusted between 1700 and 3450
RPM using the “+” and “-” arrows. Setting the
priming speed below 1700 RPM, will disable
priming and the pump will immediately begin
to run the scheduled speed.
When priming is disabled and the pump is
started, the screen will display, “
Prl
--
OFF
”
for 10 seconds while running the scheduled
speed (see Figure 11). This 10 second
delay allows time to enable priming by pressing “+”.
If priming is re-enabled, the pump will transition from
the scheduled speed to 1700 RPM. If necessary,
priming speed can then be increased 1700 RPM by
pressing “+”. The 5 minute priming countdown timer
starts when priming is first engaged.
Priming time 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.
Test and verify priming speeds more than once, letting
the water drain from the system in between each test.
Note: To prevent air from entering the system, the
pump strainer pot should always be filled with water
up to the bottom of the suction port.
