AIRFLOW & PRODUCT LOAD
Hillphoenix cases provide maximum product capacity within the
refrigerated air envelope. Please keep products within the ap-
propriate load limit.
It is important that you do not overload the food product display
so that it
impinges on the airfl ow pattern (Fig. 8). Overloading
will cause malfunction and the loss of proper temperature lev-
els. The designed load limit is 3" above the deck for critical tem-
perature products and 6" for non-critical temperature products.
For full technical reference drawings with load limit lines refer
to pages 4-6.
DEFROST
Cases are equipped with Temperature Terminated Off-Time
defrost.
The defrost cycle is very important in that it ensures correct
operation of the case. It is activated and controlled by the
thermostat which temporarily stops the condensing unit, al-
lowing the evaporator to shed the build-up of ice. The control-
lers synchronize the defrost between condensing units via the
auxiliary ports.
W A R N I N G
Always keep product within the designated air
curtain. Failure to do so may result in case
malfunction and product losing proper tempera-
ture, resulting in sub-standard operation and
increased chances of food contamination.
