Verify the
temperature recovery time
after door
opening by performing the following steps.
Let the appliance
stabilize
and thereafter open the
door for
1 minute
(only one door shall be opened on
1400 models). Note the time of opening the door and
the temperature of the test probe placed in the cen-
ter of the appliance. For 1400 models, note the tem-
perature of both center probes and base the result
of the average value of these probes.
When 1 min. has passed, close the door and note the
time.
Monitor the temperature of the test probe until it has
reached a temperature value within the normal op-
erating temperature (set point +/- hysteresis) and
note the time and value.
Calculate the recovery time and note it.
Approval criteria

HIGH TEMPERATURE ALARM TEST
PROCEDURE
RESULT
PASSED (YES/NO)
Verify the function of the
high temperature alarm
by
performing the following steps.
Let the appliance
stabilize:
Refrigerators: +4°C
Freezers: -20°C
Note the setting of the
AH parameter
.
Open the door and wait until the high temp. alarm
level (set point + AH value) is reached plus the time
of the Ad (AH/AL delay) setting (see
examples
in
point
3.1
). During this process the door open alarm
(dor) will be activated, however, this will not affect the
high temp. alarm test.
Approval criteria
-
Refrigerator:
Activation of the acoustic and visu-
al HI alarm according to the AH (high temp.
alarm) + Ad (AH/AL alarm delay) settings ( = acti-
vation of alarms 5 minutes after re9°C)
-
Freezer:
Activation of the acoustic and visual HI
alarm according to the AH (high temp. alarm) +
Ad (AH/AL alarm delay) settings ( = activation of
alarms 5 minutes after reaching -12°C)
Note set point:
AH setting:
