4.2 WATER PRESSURE ADJUSTMENT (ONLY FOR
MODELS 6 GN 1/1 C2-C3 AND 10 GN 1/1 C2)
For correct operation of these appliances, in addition to the
requirements stipulated in point 4.1 above, the water pressure
must also be adjusted using the relative internal pressure
regulator. To adjust the water pressure, proceed as follows (Fig.
"11"):
1) Remove the LH side panel from the oven;
2) Start a steam cooking cycle (see "Instructions for use");
3) Undo knurled cap "A";
4) Using a flat-blade screwdriver, turn the screw underneath until
the read-out on pressure gauge "B" is 120 kPa (1.2 bar);
5) Refit cap "A" and remount the side panel.

4.3 WATER DRAIN SYSTEM (Fig. 12a-12b)
Connect drain fitting “C” to a drain pipe of the same
diameter which is between 0.5 and 3 metres in length and
is resistant to temperatures of at least 100°C. The drain pipe
must be siphoned (height 80 mm) to an open drain “O” (“Air-
Break”) or floor grating (see Fig. 12b) in order to prevent any
back-flow from the sewage system from reaching the piping
inside the oven or oven chamber.
Check the hoses and elbows on metal pipes for kinks or pinching
along the entire drain line and make sure the drain line has a
minimum gradient of 5° to prevent water from collecting inside
the system.
Important: The drain system must be installed so that any
vapours from the open drain do not enter the aeration vents
under the appliance.
Note for model 6 GN 1/1 C4:
This model is fitted with two separate drain fittings (see installation
diagram). These fittings must be connected to each other externally
on the appliance before flowing into a single drain.
