Water drain

• A drain pipe comes out of the rear of the appliance (see the attached “Technical Data Sheet”) to drain the cooking chamber. This pipe must be connected to piping with 30 mm internal diameter (DN 30) resistant to steam temperatures (90°C-100°C): avoid metal ones.
• The piping must be rigid and must not have bottlenecks along the discharge path (it is advisable to use commercial pipes of special plastic material, with an internal “sealing” O-RING, and to limit the use of “elbow” bends).
• The piping must also maintain a steady slope (min. 4-5%) along its entire length.
• The considered length is that of the drain pipe of the appliance to the discharge point and must not exceed the measurement of 1.5 meters.
• It is mandatory to connect the appliance’s drain to the grey water network through an adequate trap, in order to stop steam/odours from coming out of the drain. The connection to the drain water must be set up separately for each appliance; with multiple appliances connected to the same drain pipe, ensure that the pipe is suitably sized to assure regular drainage with no hindrances.

Water drain for floor ovens
The drain pipe is conveyed to an open (grilled) floor drain (Fig.3) and should not go into direct contact with the discharge point: the “air gap” (distance between the drain pipe coming from the appliance and the open drain) must be at least 25 mm. Wall-mounted discharge is also allowed as long as the drain pipe maintains the steady slope of 4-5%.

Water drain for tabletop ovens
The exhaust pipe can be conveyed to an open (grilled) floor drain (Fig.4); otherwise, between the drain pipe of the appliance and the drain point with a “collection cup” (Fig. 5), there must be a height difference of at least 30 cm in order to facilitate regular flow of water. In any case, the “air gap” (distance between the drain pipe from the appliance and the open drain or the “collection vessel” of the drain duct pipe) must be at least 25 mm.
Wall-mounted discharge is also allowed as long as the drain pipe maintains the steady slope of 4-5%.

Steam drain

• The appliance is equipped with a special metal pipe (DN30) for the discharge of steam from the cooking chamber.
• No other type of pipe can be connected to this pipe, which protrudes from the back of the casing.
• Failure to comply with this specific prohibition shall relieve the Manufacturer from any liability concerning the potential malfunction of the appliance and poor cooking quality.
• Increasing the length of the original drain hose may result in the formation of abnormal “condensation” in the cooking chamber.
• To prevent steam from escaping from the exhaust pipe, place the appliance under the extractor hood, or
• connect it to the” extractor hood/condensing hood, specific for the appliance model used.

Safety thermal device
The appliance is equipped with a (manually reset) safety thermostat, to protect against excessive and hazardous overheating which might accidentally occur inside it. If the safety thermostat trips, the power supply to the appliance is cut off. The safety thermostat is located at the back (bottom) of the appliance (see the attached “Technical Data Sheet”); to reset it after it has tripped, unscrew the protective cap using an appropriate tool and press the “reset” button all the way. Replace the protective cap so that it cannot be unscrewed without the use of a tool.
Important
The safety thermostat should only be reactivated after eliminating the functional anomalies that caused it to trip. This can only be done by a Service technician.

Electronic circuit protection
The electronic circuit of the microprocessor cards housed inside the “electronic component drawer” is protected by fuses. If they “blow” they must be replaced with equivalent fuses with the same electrical and dimensional characteristics.
Important
“Blown” fuses should only be replaced after eliminating the anomalies that caused them to blow. This can only be done by a Service technician.

Replacing the cooking chamber gasket
The cooking chamber gasket has a rigid profile with retaining fins. This profile must be inserted in the suitable perimeter seat on the “front” of the chamber. To replace the gasket, simply remove the used one from its seat (pull tightly near the 4 corners) and, after cleaning any impurities from the seat, insert the new gasket (to facilitate the assembly, it is recommended to wet the profile of the gasket with soapy water).

Handle closure adjustment

• Should the door handle not close properly, check and if required adjust the position of the “nose” (cross-shaped) as follows:
• with the oven door open, loosen the 2 screws that secure the “nose” support;
• move the support vertically (upwards or downwards) and fasten it so that when the door is pushed with the handle completely open (horizontal position), the “nose” can fit into the handle without rubbing.
• after adjustment, with the door closed, the handle must be in a perfectly vertical position (the end portion of the “nose” must be perfectly horizontal).
• Warning
  The door handle must only be adjusted after positioning the oven in a perfectly horizontal (levelled) way.

Checking the cooking chamber gasket “seal”
If the gasket on the “front” of the cooking chamber does not ensure proper “sealing” on the inside glass of the door, adjust the position of the 2 hinges (upper and lower) of the door and/or the (cross-shaped) handle “nose” projection by doing the following: Loss of “tightness“ on the hinges side With the door closed, loosen the 6 screws securing the lower hinge (3 screws) and upper hinge (3 screws) of the door; push the door slightly to the side of the hinges so that the inner glass leans on the “front” gasket; hold the door slightly pressed in the direction of the hinges and secure them by tightening the 6 previously loosened screws. At the end of the operation, visually check, on the hinged side, that the door is perfectly parallel to the “front” of the cooking chamber.

Loss of “tightness“ on the “nose” side
With the door open, loosen the locknut that secures the “nose” to its support; screw (clockwise) the “nose” by a full turn so that the end (cross-shaped) piece is perfectly horizontal again; screw on the previously loosened locknut. At the end of the operation, close the door, and check for slight resistance when turning the handle: this means that the “front” gasket is pressing (“sealing”) slightly on the inside glass of the door.
If you do not feel any resistance, repeat the entire operation by screwing on the “nose” another full turn.
Warning
After performing all the operations necessary to restore the proper “sealing” of the gasket on the inside glass of the door, check its tightness by running the oven: for at least 30 minutes, with a 100% humidification cycle and with a cooking chamber temperature of 110°C. During oven operation no steam must escape from the door.

Residual risks

• Do not use the door handle to move the appliance: this may deform the door frame.
• The appliance is fitted with electrical parts: it must never be washed with a water or steam spray.
• The appliance is electrically connected: disconnect the power supply before performing any type of maintenance.
• To avoid incorrect connections of the appliance, the relevant electrical/water connections are marked on the appliance by suitable identification plates.
