Starting and operating the spa.
Wash the spa with warm water. Close drain valve. Turn on main switch.
Water will then be added until the skimmer is ½ to ¾ covered. After filling, start filter pump using the
on/off switch on the side of the tub control panel. The system is now in operation. Remember to
aerate the sand filter using the screw on the side of the multi-port valve.
The electric heater is turned on and off automatically depending on the temperature set on the remote
control. The actual temperature in the tub is displayed on the remote control.
The chlorinator constantly adds chlorine.
Check pH daily
. A pH of 7.2-7.6 is recommended.
To lower pH, add pH-minus directly to the water in the spa. Add only a little at a time.
Check chlorine level daily.
A CL value of 1.0 is recommended. If chlorine level rises, turn down
chlorinator. Similarly, if chlorine level falls, turn up chlorinator. Adjust chlorinator using knob on its
side. The chlorinator can be set on a scale from 0 to 8.
Important:
The chlorinator must only be serviced when the filter pump is switched off and when the ball valves
located ahead of the filter pump and after the electric heater are closed. Remember to re-open valves
after service work is completed.
Heating and chlorination occur only when filter pump is operating.
Heating 1100 litres takes approx. 130 min. Delta-T 8°C -38°C.
This does not, however, take heat emission in the technical equipment room into account.
The ball valve ahead of the electric heater
must never be closed,
but is only used for directing water
over the chlorinator.
A water temperature of 38°C is recommended.
Therapy function
Start/stop the therapy pump with touch pad.
Start/stop the fan with touch pad.
