V. Cleaning and Maintenance Instructions

WARNING

1.Do not splash water directly onto the unit. This might cause short circuit, electric shock, corrosion or failure.

2.When cleaning or inspecting the unit, turn off the power switch and unplug the unit or disconnect the main power source to prevent electric shock, by unexpected entrance of water into the unit, or injury by any moving parts.

3.To prevent frostbite, do not touch foods or containers (especially metallic) in the freezer compartment with damp hands.

4.Before using a sanitizer such as inert soap and sodium hypochlorite, thoroughly read the manufacturer’s instructions on the proper usage and amount.

IMPORTANT

1.To prevent damage to the painted or plastic surfaces, do not use the following: thinner, benzine, alcohol, petroleum, soap powder, polishing powder, alkaline cleaner, acid, scouring pad and especially those strong cleaners for use on a ventilating fan or a cooking range. Also, to prevent corrosion, do not use a chlorine bleach such as sodium hypochlorite on the stainless steel surfaces.

2.Use clean cloth and hands for cleaning.

3.Before cleaning the cabinet interior, move the stored foods into another clean refrigerator/freezer.
