Operation Manual HM550
• To quit the submenu, press the menu button (fig. 60.9).
• Now continue working with the selected settings.
• e interrupted defrosting is shown in the status line on the display
(fig. 61) as INTR.
Note:
A cancelled or interrupted defrost cycle must be repeated later on, as other-
wise the evaporator will cover completely with frost and cannot cool any-
more (see immediate defrosting, page 60).
For this reason, the function INTERRUPT is automatically reset at the
end of an interrupted defrosting (max. time approx. 1 h), i.e. the next
defrosting is carried out again at the pre-selected defrosting time.
Note:
While INT. is active, neither the defrosting time nor the real time can be
changed.
When INTR.ACT appears in the status line, this means that INTER-
RUPT was selected while defrosting should otherwise be carried out
and the next defrosting is carried out again at the next pre-selected
defrosting time.
Note:
e liquid from the daily defrosting process is collected in the container
(fig. 62.1). Please note that this container is emptied in due time according
to the safety precautions at the beginning of this operation manual.
We highly recommend to treat the container with a disinfection solu-
tion after having emptied it.
