Programming device
The machine is fitted with an electronic programmable device which can contain
a maximum of 60 different programs. Six of these programs can be chosen using
the program selection buttons.
A number of standard programs are included in the programming device on
delivery (see section, Standard programs). These programs can be modified to
suit individual customer requirements. Furthermore, completely new individual
programs can be programmed directly into the machine from the machine
control panel. If desired, the whole or parts of a standard program can be used as
the basis for programming.
Programming may only be carried out by authorized personnel.
Door function
Decomat 4656 can be provided with one or two doors. Doors are fitted with an
electrical interlocking system to prevent opening during the program sequence.

Two doors are required where it is necessary to separate the soiled and cleaned
side of the machine. Operation will then be as follows:
It is never possible to open both doors at the same time. The door on the soiled
side remains unlocked prior to starting and the door on the cleaned side will be
locked. Both doors are locked on pressing the starting button. On completion of
the program sequence, the door on the clean side will unlock but the other door
will remain locked. The cleaned dishware can then be removed whereafter the
door should be closed again, causing it to lock and the door on the soiled side to
unlock in preparation for the next sequence.

separate part of the program.
The machine cannot be started if the detergent bottle is empty. The message
”FILL DETERGENT” will be displayed when the detergent bottle becomes
empty.
A third dispenser system can be installed if required, eg, for chemical
disinfection of heat-sensitive dishware.
If the machine is not provided with drying, it is recommended that the dishware
is dried in a separate dryer cabinet.

If necessary
Decomat 4656Operating instructions
The washing chamber
The washing chamber should be kept free of limescale deposits. Remove
remaining deposits by spraying on a normal acid-based detergent. Then run a
program to cleanse the washing chamber (if the correct dosage of descaling
compound is used, this should not normally be necessary).
The exterior
The front and side walls can be cleaned and disinfected with an alcohol-based
detergent, surgical spirit, or normal detergent. The control panel can be cleaned
in the same way.
Remove marks with ordinary stain-remover for stainless steel.
If the disinfector is used without automatic descaling, the steam generator must
be checked regularly for limescale deposits.
