WARNING:
The completed installation must make sure the refrigerator is completely isolated from its heat generating
components through the correct use of baffles and panel construction.
Certi
other installation method voids both the certification and the factory warranty of the refrigerator.
The bottom of the opening for the lower intake vent, which is also the service access door, must be even with or immediately below the
floor level.
CSA International certification allows the refrigerator to have zero (0) inch minimum clearance at the sides, rear, top, and bottom.
While there are no maximum clearances specified for certification, the following maximum clearances are necessary for correct
refrigerator performance:
Bottom 0 inch min.
Each Side 0 inch min.
Top 0 inch min.
Rear 0 inch min.
These clearances plus the lower and upper vents allow the natural air draft that is necessary for good refrigeration. Cooler air comes in
through the lower vent, goes up around the refrigerator coils where it removes the excess heat from the refrigerator components, and
goes out through the upper vent.
The refrigerator also has two thermostat controlled fans to move air across the cooling system. These fans turn on when the condenser
fin temperature at the thermostat is about 130° F or higher and only when the refrigerator controls are on. These fans turn off when the
condenser fin temperature at the thermostat is about 115° F or less. Even with these fans, if the air flow is blocked or decreased, the
refrigerator will not cool correctly.
Each NORCOLD model is certified by CSA International for correct ventilation. Install only the certified vents that are listed in this
manual.
