Commissioning and Operation
3.3 Start-up and Operation
3.4 Switching the power supply
on and off for the first time
The drain valves for emptying the hot tubs are factory closed. Before
filling the spa, this has to be rechecked.
The valves are closed when the rotary handle is across the direction of the line.
The valves are open when the handles are in the direction of the line.
With the drain valves closed, fill the spa with fresh tap water up to the skimmer
mid-level. This is marked on the Skimmer face plate with the word „Water
level“ (Strato 2.0). With Strato 2.3 and Wave it is the level halfway between
the skimmer and the acrylic cover. Filling the water level over this mark leads
to a poor skimming action.
Filling the spa under this level can lead to air entering the pipework system and
the system may turn off (Error message: 3.6.17 or M028). If the pool is being
used by several people at once or very large people, it may be useful to keep
water levels lower.
To drain the hot tub open all drain valves, switch off the power supply at the
main fuse box.
„Priming“-Modus-M019*
After the initial start-up sequence, the control will enter Priming Mode and
display a Priming Mode screen. Only pump icons appear on the priming mode
screen. During the priming mode, the heater is disabled to allow the priming
process to be completed without the possibility of energizing the heater
under low-flow or no-flow conditions. Nothing comes on automatically, but
the pump(s) can be energized by selecting the “Jet” buttons. If the spa has
a Circ Pump, it can be turned on and off by pressing the “Circ Pump” button
during Priming Mode.
Priming the Pumps
As soon as the Priming Mode screeen appears on the panel, select
the “Jets 1” button once to start Pump 1 in low-speed and then again to
switch to high-speed. Also, select the other pumps, to turn them on. The pumps
should be running in high-speed to facilitate priming. If the pumps have not
primed after 2 minutes, and water is not flowing from the jets in the spa, do not
allow the pumps to continue to run. Turn off the pumps and repeat the process.
Note: Turning the power off and back on again will initiate a new pump priming
session. Sometimes momentarily turning the pump off and on will help it to
prime. Do not do this more than 5 times. If the pump(s) will not prime, shut
off the power to the spa and call for service.
Important: A pump should not be allowed to run without priming for more
than 2 minutes. Under NO circumstances should a pump be allowed to run
without priming beyond the end of the 4-5 minute priming mode. Doing so
may cause damage to the pump and cause the system to energize the heater
and go into an overheat condition.
