CASE VENTILATION

AIR FLOW:
Sources of heat or air
flow external to the
cabinet should be
avoided; i.e. ventilation
ducts, open doors, and
direct sunlight. This will
deter external air from
disrupting the air flow
from the cabinet thus
will help to maintain its
performance.

LOCATION:
The refrigeration case should be positioned in a manner
that optimal air flow can flow through the underside
and rear. This will minimise the risk of condensation on
the back and/or underside. Leave a minimum 75mm
gap between the rear of the case and the back wall.
Min. 75mm
STOCKING SHELVES:
When stocking the shelves, be sure to leave a 25mm
gap in between the stock and the above shelf to ensure
even and consistant airflow. Not doing this correctly
may result in a blockage of airflow which could freeze
the stock at the rear, and not enough refrigeration to be
produced toward the front of the case.
NO OBJECTS ON CASE:
place objects, stack, or use the top of
the case as storage. Object may fall
and cause injury to personnel and/or
damage to the case.
