Use
When the appliance is switched on and has been running for 2 minutes, both motors will stop to allow repositioning of the
by-pass valve. The motors will start up again after approximately 1 minutes.
N.B.
: this is a normal system procedure and should not be perceived as a malfunction.
The appliance is rated for continuous duty.
The appliance is wired to a special dedicated control panel, the functions of which are described further on. This model can
be used in combination with a Vortice preheater, which must be fitted and set up by the installer. The minimum distance of
the preheater from the appliance is 500 mm.
