GENERAL INFORMATION Thank you for choosing Hill PHOENIX for your food merchandising needs. This handbook contains important technical information and will assist you with the installation and operation of your new Hill PHOENIX display cases. By closely following the instructions, you can expect peak performance; attractive fits and finish; and long case life. We are always interested in your suggestions for improvements (e.g. case design, technical documents, etc.).
INSTALLATION MOVING CASES Hill PHOENIX display cases are generally shipped to stores with casters installed on the base frame. The casters make the job of moving cases easier for everyone involved in the shipping and installation process, as well as reducing the chance of damage from raising and lowering cases with ”J” bars to place them on dollies, skates or rollers. In most situations, one or two persons can easily move the case into position.
REFRIGERATION PIPING Refrigeration components for OWZA cases are easily accessible in the tank and beneath the case. The diagram on page 7 illustrates all of the refrigeration components in the case – the box-shaped dotted line indicates those components that are located within the case tank. The expansion valve and suction line 1/4” access valve are both located on the front-left side of the tank and are accessible without lifting the fan plenum.

PLUMBING The “P” trap assembly – attached to the case at the factory so no assembly is required – directs the case drainage to the drain pan. outlet is specially molded with PVC material and the “P” trap is constructed of PVC. Care should be given to make certain that all connections are water tight and are sealed with appropriate PVC primer and PVC cement. The case drain is located front-and-center in the case for convenient access – simply remove the front kick plate.
ELECTRICAL CONNECTIONS The OWZA comes pre-wired with a NEMA L14-30P twistlock plug (250 volt, 4-prong). For export models, a NEMA L6-30 twist-lock plug (250 volt, 3-prong) is used. tion utilizes on the right-hand controller. The case is turned ON/OFF via an electric breaker that is located on the electrical junction box, in the left-hand side of the case behind the front kick plate. Dual Dixell XR03CX digital controllers are provided for case operation and programming.
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 lowor medium-temperature defrost modes. Switching between the two different temperature modes is easily done by using a special 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.
USE & MAINTENANCE CASE CLEANING Cases are designed to facilitate cleaning. All surfaces pitch to a deep-drawn drain trough that angles toward the front-center of the case where the waste outlet is located for easy access. The coil is covered to prevent waste fluids from entering, but it is easily accessible for cleaning: simply remove the two coil-cover fasteners, then lift and remove the coil cover.
