8.5 • DRAINING
The water is drained off by gravity through
a heat-resistant pipe DN 50 (not flexible),
maximum length 2 m, installed at an angle
of no less than 4°.
Mean temperature of the drain water: 65 °C.
For the range with the drain as per fig.1 it is
possible to make a direct connection with an air
trap, without fitting a drain cup, as the drainage
manifold system has an internal air drop (Fig. 2).
With a drain on the floor without an air trap it is
necessary to have an outlet clearance of 2 cm
(Fig. 3).
Fig. 2
For the remaining models it is imperative to
fit a drain cup to ensure a minimum air drop of
25 mm. between the appliance's plastic drain
elbow and drain line. A direct connection is not
permissible.
WARNING:
The drain line must be outside the perimeter of the oven.
It is prohibited to reduce the drain diameter.
