AIR FLOW, Defrost & Temp Control

DEFROST & TEMPERATURE CONTROLS

OWZA cases are equipped with both Electric (low-temp) and Timed-Off (medium-temp) defrost and can be run in either low- or medium-temperature defrost modes. Switching between the two different temperature modes is easily done by using a spe- cial key switch located on the left-bottom-front of the case (see Fig. 3).

ing the front kick plate and lower front panel, see the trim out section of this manual on page 5.

It is important to consult the control setting guidelines shown on page 2 before setting the defrost schedule. Further adjust- ments may be required depending on store conditions.

AIR FLOW & PRODUCT LOAD

The rear baffle (see diagram below) contains the sensor bulb and probe for electric defrost termination; the sensor bulb for temperature control; and the discharge air probe.

The defrost termination control thermostat and the temperature control thermostat are located in the junction box underneath the case on the bottom-left side (see diagram below). To ac- cess the thermostats, you must first remove the front kick plate, then remove the junction box cover. For instructions on remov-

Cases have been designed to provide maximum product capac- ity 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 display so that it impinges on the air ﬂow pattern. Overloading will cause malfunction and the loss of proper temperature levels, particularly when discharge and return air sections are covered.
