Internal Light
If the Medi+ refrigerator is fitted with an optional
light(s), an independent light switch will be provided,
which will allow control over the internal light(s).
DEFROST OPERATION
The controller will instigate an automatic defrost
cycle. The refrigeration system is turned off whilst
the electric defrost system is switched on. This
defrosts the evaporator coil. The operation raises
the temperature of the Medi+ cabinet slightly for a
short period but does not affect the stored product.
When defrost is in progress, the defrost indicator on
the control panel will become illuminated and
“dEF”
is displayed until the defrost cycle has finished.
A manual defrost can be activated by pressing and
holding the
“▼”
button on the controller for 2
seconds.
