Clearance Requirements
• Keep the vents clean and free of obstruction.
• Casters or optional legs must be used and not removed.
• Provide good air circulation inside and outside the
cabinet.
• Do not pack refrigerator so full that air cannot circulate.
• Avoid hot corners and locations near stoves and ovens.
• These cabinets have Delfield’s “front-breathing” design.
They may be installed flush against a wall or built into a
counter as required.
• The louver at the floor level must be kept completely
clear of any obstructions. Proper operation is dependent
on air being able to flow freely through the front louver.
The louver at the back of the cabinet is not necessary for
proper operation, but any air flow through it is beneficial.
Caution
,
Any restriction of the proper air flow outlined above,
total or partial, will void the warranty on the cabinet.
