case on the bottom-left side (Fig. 5).   To access the thermo-
stats, you must first remove the kick plate, then remove the 
junction box cover.  For instructions on removing the kick-
plate, see the Trim Out section of this manual on page 6.

It is important to consult the control setting guidelines shown 
on page 2 before setting defrost times. Further adjustment 
may be required depending on store conditions.

AIR FLOW & PRODUCT LOAD

Hill PHOENIX cases provide maximum product capacity 
within the refrigerated air envelope.  Please keep products 
within the load limit line shown on the diagram below.

It is important that you do not overload the food product dis-
play so that it impinges on the air 

fl

 ow pattern.  Overloading 

will cause malfunction and the loss of proper temperature 
levels, particularly when discharge and return air sections 
are covered.

DEFROST & TEMPERATURE CONTROLS

UPL-NRG cases are equipped with Timed-Off defrost.

The rear baffle (Fig. 5) contains the sensor bulb for tem-
perature control and the discharge air probe.  The defrost 
termination control thermostat and the temperature control 
thermostat are located in the junction box underneath the
