Replacing The Cooking Chamber Gasket; Handle Closure Adjustment; Checking The Cooking Chamber Gasket "Seal - eka MKF 464 S Translation Of Original Installation And Maintenance Manual

4.3 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).

4.4 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.

4.5 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.
