4.2 Safety thermal devices
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 is activated, 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.
The steam generator for the appliances that include it (versions “V TS” and “V C TS”) is equipped with a
(manually reset) thermostat for heating resistor overheating protection. If the safety thermostat is triggered,
the power supply to the heating resistor is cut off.
The safety thermostat is located near the steam generator and is accessed by removing the back of the
appliance; to reset it after it is triggered, press the "reset" button all the way.
Important
Safety thermostats should only be reactivated after eliminating the anomaly that caused them to trip. This
can only be done by a Service technician.
4.3 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.
4.4 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 seal, simply remove the used 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).
4.5 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 the 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.

13
4.6 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 (3 screws) and upper (3 screws) hinges 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 screwing on 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.
4.7 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 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.
Only for wheeled models (MKF 1664 TS –MKF 2011 TS)
After installing the oven, ensure the tray trolley can be handled with ease, on smooth floors and
with no hindrance to insertion and extraction operations: the trolley is mounted on wheels, any
collision may cause the hot cooking food and/or liquids to spill and may even cause it to tip over.
4.8 Disposal of the appliance/packaging
The appliance is made of recyclable raw materials and does not contain any substances that are toxic or
hazardous to man and the environment. The ultimate disposal of the appliance and its packaging must be
carried out strictly following the regulations in force in the country of installation. The different materials it is
made up of must be separated by type and delivered to the suitable collection centres. Always adhere to the
environmental protection regulations.
