AIRFLOW & DEFROST
13
Defrosting
The defrost cycle is very important in that it ensures correct
operation of the cabinet. It is activated and controlled by the
thermostat which temporarily stops the condensing unit,
allowing the evaporator to shed the build-up of ice. Fan speeds
during defrost and refrigeration are independently adjustable
using the Rheostat boards shown in Figure 7 on Page 9 (Items
C & D). The default settings utilize a higher fan speed during
defrost to minimize off time and ensure a clear coil. For factory
settings see page 2 of this manual ‘TECHNICAL DATA’.
AIRFLOW & PRODUCT LOAD
Hillphoenix cases provide maximum product capacity within
the refrigerated air envelope. Please keep products within the
appropriate load limit.
It is important that you do not overload the food product
display so that it impinges on the airfl ow pattern (Fig. 11).
Overloading will cause malfunction and the loss of proper
temperature levels.
The refrigerated case is marked with a line to indicate the load
limit (see Fig. 12).
Adequate refrigeration is only guaranteed for products that
is displayed below this line. Arranging the goods in a uniform
manner ensures the best possible working effi ciency of the
display case.
It is good practice to carry out rotation of stock when refilling
the cabinet with new products. Older products must be sold
first. Products must not obstruct air vents.

N O T E
Proceed to the loading only once the display case
has reached the proper temperature setting.
F O R B I D D E N
DO NOT OVERLOAD THE CASE:
this is the most
common error and can cause secondary faults
and malfunctions (e.g. blocking the evaporator by
obstructing cold air outfl ow). Note also that products
lying above the load limit line will not be properly
refrigerated and this will inevitably cause their rapid
deterioration.
F O R B I D D E N
1. Do not load products above the load limit line.
2. Do not tamper with safety devices. Any tampering
shall render the warranty null and void and shall
exonerate Hillphoenix from any liability with
regard to users of the refrigerated display case.
3.
Do not stand on any part of the refrigerated
display case.
4.

of the refrigerated case unless an authorized
service technician.
5. Do not use water jets directly to clean the
cabinet.
6. Do not remove the electrical panel front cover.
7. Do not attempt to remove build-ups of ice with
sharp objects.
8. Do not clean with acid products or products with
a strong degreaser or corrosive action; do not
use abrasive sponges.
