PROTECTIVE
:
VINYL
This adhesive vinyl (included inside the packing) protects the instruments against
water drippings, as in commercial refrigerators, for example. Do the application after
finishing the electrical connections.
Remove the protective paper
and apply the vinyl on the entire
superior part of the device,
folding the flaps as indicated by
the arrows.
