NSTALLATION
MOVING CASES
Hill PHOENIX FEA fl oral display cases are equipped with lower structural tubes (see Fig. 1) that run the length of the case. These tubes are designed to allow the case to be moved into position by a forklift operator.
FLOOR PREP
1. Ask the general contractor if there have been changes in the building dimensions since the print you are using was issued. Also, ask for the points of reference from which you should take dimensions to locate the cases.
2. Using chalk lines or a laser transit, mark the fl oor where the cases are to be located for the entire lineup. The lines should coincide with the outside edges of the lower structural tubes.
3. Leveling is necessary to ensure proper case function and to avoid potential damage. Locate the highest point on the positioning line as a reference for determining the proper height of the shim-pack levelers. A laser transit is recommended for precision and requires just one per­son.
4. Locate the position of the lower structural tubes and spot properly leveled shim packs at the appropriate locations.
LOWER
STRUCTURAL
TUBES
Fig. 1 Attaching the front and end kick plates.
LINE-UP & INSTALLATION
1. Move the case into position, being certain to leave at least 6" of ventilation space at the top and back of the case.
2. Using a “J” bar , raise the end of the case (under cross support) and place the lower structural tubes on the shim packs. Repeat on the other end of the case.
3. Once the lower structural tubes are properly placed on the shim packs, check the vertical level by placing a bubble level plumb to the rear edge of the case; then add/remove shim levels as needed. To check the hori­zontal level, repeat this process after placing the bubble level on the rear sill.
WARNING
Be certain that your hands and feet are out of the way before lowering the case after the removal of the cast­ers. Failure to do so may result in serious injury.

ONDENSATION
The condensate pumps have been designed to remove excess moisture that is created during the operation of the case. The drain outlet is located beneath the deck pans in the front-center section of the case.
Pump 1 pushes the condensate up through the rear area of the case into the condensate reservoir in Pump 2. Pump 2 then carries the condensate out of the top of the case through a 30-foot long, clear vinyl 3/8" ID hose with quick connect, emptying into the store's drainage system.
Pump 2 is provided with an emergency fail-safe switch de­signed to turn off Pump 1 as Pump 2 reaches its maximum
MODEL
FEA
capacity. Pump 2 will continue to pump until the switch is turned off. Each pump must remain plugged into its design receptacle for the emergency fail-safe switch to operate properly.
An optional heated condensate pan may be substituted for pump 2. The same receptacle is used; however, the emer­gency fail-safe switch and wiring are removed.
Care should be given to assure that all connections are water tight and properly sealed.

GENERAL INFORMATION
The Hill PHOENIX LED power supplies are located inside the grounded, sheet-metal structure of the display case in the same location that the T8 ballast would normally oc­cupy – typically a slide out ballast tray under the case or in the cornice area.
The LED lighting system has an ON/OFF switch that is lo­cated in the upper left-hand corner of the lighting assembly. Once cases have been properly positioned in the store and the electrician has connected the lighting circuit, Hill PHOENIX luminaires may be turned on to verify that all lights are connected and working properly.
To ensure peak performance, it is advisable to run the LED lights only when the store climate control is on and case
refrigeration is started. NOTE: it is highly recommended
that the ambient store temperature not exceed 80F.
Once store power is connected and the light circuit is en­ergized, the LED system should operate without the need
for any signifi cant maintenance for several years. Should a power supply need to be removed and/or replaced, turn off the power to the case before proceeding. Be certain to replace the power supply with genuine Hill PHOENIX parts or a comparable UL-listed Class-2 rated regulated 24V DC power supply with 100W output capacity.
REMOVING SHELF LUMINAIRES
1. Unplug the luminaire.
Re-installing shelf luminaires:
1. Place hook into shelf roll form at shelf front and rotate rear of luminaire toward the shelf.
2. Depress the rear clip so that luminaire can fi nish rotation and until clip engages the shelf bracket.
REMOVING NON-SHELF LUMINAIRES
2. Pinching the latching clips inward at the ends of the luminaire, rotate luminaire up at each end until hooks are free, then remove.
DANGER
SHOCK HAZARD
Always disconnect power to case when clean­ing, servicing or confi guring components of the LED lighting system. Failure to do so may re­sult in serious injury or death.
WARNING
Using improper DC power supplies may dam­age the luminaires, resulting in sub-standard operation and increased chances of safety issues/injury.
WARNING
Never replace a 24V DC power supply with a T8 or T5 ballast of any kind! Ballasts use alternating current (AC) instead of direct cur­rent (DC) and operate at a much higher volt­age than is used by this LED system. Doing so will damage the LED system and increases the chance of safety issues/injury.
1. Simultaneously squeeze
the plastic clips at each end.
Re-installing a non-shelf luminaire:
1. Align the 4-pole jack with the 4-pole connector on the clip-in LED luminaire.
2. Push into place – side clips will engage on the sheet metal of the case.
3. Fasten anti-tamper bracket into sheet metal of case with #8 screw at end opposite the 4-pole in-line con­nector.
2. When the hooks are disen­ gaged, pull the luminaire free.

AIR FLOW
FEA cases have been designed to provide maximum prod­uct capacity within the refrigerated air envelope. It is impor­tant that you DO NOT overload the food product display to avoid impinging 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. Please keep products within the load-limit lines shown on in the diagram below.
DEFROST & TEMP CONTROLS
The defrost and temperature controls of FEA cases are initiated by a Dixell XR03CX rack controller.
MODEL
FEA
The single time-off defrost is initiated by the Dixell XR03CX controller mounted in the electrical control box. During de­frost, all valves close and the pump cycles OFF.
It is important to consult the guidelines and control setting shown on page 4 before setting defrost times. Further ad­justment may be required depending on store conditions.
Dixell controller information and setpoints are located in this manual's Appendix section.

CASE CLEANING
Hill PHOENIX cases are designed to facilitate cleaning. All surfaces pitch to a deep-drawn drain trough that angles to­ward the front of the case where the waste outlet is located for easy access.
CLEANING PROCEDURES
A periodic cleaning schedule should be established to maintain proper sanitation, insure maximum operating efficiency, and avoid the corrosive action of food fluids on metal parts that are left on for long periods of time. We recommend cleaning once a week.
To avoid shock hazard, be sure all electrical power is turned off before cleaning. In some installations, more than one disconnect switch may have to be turned off to completely de-energize the case.
• Check waste outlet to insure it is not clogged before starting the cleaning process and avoid introducing wa­ter faster than the case drain can carry it away.
Avoid spraying cleaning solutions directly on electrical connections.
Allow cases to be turned off long enough to clean any frost or ice from coil and pans.
Use mild detergent and warm water. When necessary, water and baking soda solution will help remove case odors. Avoid abrasive scouring powders or pads.
Under no circumstances should abrasive cleaning solu­tions such as scouring powders or steel wool be used to clean non-glare glass.
• Use warm water and a disinfecting cleaning solution when cleaning underneath the cases.
When removing deck pans for cleaning, gently set the pans on the ground in a vertical position up against the front of the case. If equipped with the optional quick connects, disconnect the coolant lines from the pans for cleaning. Use warm – not hot – water when cleaning the deck pans.

PLEASE READ BEFORE USING THIS MANUAL
1. This manual is part of the product and should be kept near the instrument for easy and quick reference.
2. The instrument shall not be used for purposes different from those described hereunder. It cannot be used as a safety device.
3. Check the application limits before proceeding.
SAFETY PRECAUTIONS
Check the supply voltage is correct before connecting the instrument.
Do not expose to water or moisture: use the controller only within the operating limits avoiding
sudden temperature changes with high atmospheric humidity to prevent formation of condensation
Warning: disconnect all electrical connections before any kind of maintenance.
Fit the probe where it is not accessible by the End User. The instrument must not be opened.
In case of failure or faulty operation send the instrument back to the distributor or to “Dixell
S.p.A.” (see address) with a detailed description of the fault.
Consider the maximum current which can be applied to each relay (see Technical Data).
Ensure that the wires for probes, loads and the power supply are separated and far enough from
each other, without crossing or intertwining.
In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with inductive loads could be useful.
3. GENERAL DESCRIPTION
The XR03CX, in 32×74 x50mm short format, is microprocessor based controller suitable for applications on normal temperature refrigerating units. It provides two relay output: one for compressor and th e other one for alarm signalling or as auxiliary output. It provides an NTC probe input and a digital input for alarm signalling, for switching the auxiliary output or for s tart defrost. The instrument is fully configurable through special parameters that can be easily progr ammed through the keyboard or the by HOTKEY.
The XR04CX, in 32×74 x50mm short format, is microprocessor based controller suitable for applications on normal or low temperature refrigerating units. It provides two relay output: one for compressor and the other one for defrost. It provides two NTC probe inputs, one for room temperature and other one to control defrost termination. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard or the by HOTKEY.
4. REGULA TION
The regulation is performed according to the temperature measured by the thermostat probe with a positive differential from the set point: if the temperature increases and reaches set point plus differential the compressor is started and then turned off when the temperature reaches the set point value again. In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters “Cy” and “Cn”.
5. DEFROST
XR03CX
Defrost is performed through a simple stop of the compressor. Parameter “id” controls the interval between defrost cycles, while its length is controlled by parameter “Md”.
XR04CX Two defrost modes are available through the “td” parameter:
td=EL → defrost through electrical heater (compressor OFF)
td=in hot gas defrost (compressor ON).
Other parameters are used to control the interval between defrost cycles (id) ), its maximum length (Md) and two defrost modes: timed or controlled by the evaporator’s probe. At the end of defrost dripping time is started, its length is set in the dt parameter. With dt=0 the dripping time is disabled.

8. DIGIT AL INPUTS
The free voltage digital input is programmable in different configurations by the “iF” parameter. DOOR SWITCH (iF=do)
It signals the door status and the corresponding relay output status through the “dC” parameter: no = normal (any change); Fn = Fan OFF; CP = Compressor OFF; FC = Compressor and fan OFF. Since the door is opened, after the delay time set through parameter “di”, the door alarm is enabled, the display shows the message “dA” and the regulation restarts if rd = y. The alarm stops as soon
1592020130
as the external digital input is disabled again. With the door open, the high and low temperature alarms are disabled.
EXTERNAL ALARM (iF=EA)
As soon as the digital input is activated the unit will wait for “di” time delay before signalling the “EA” alarm message. The outputs status don’t change. The alarm stops just after the digital input is de­activated.
SERIOUS ALARM (iF=bA)
When the digital input is activated, the unit will wait for “di” delay before signalling the “CA” alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de­activated.
SWITCHING SECOND RELAY ON (iF=Au) When o1=Au it switches on and off the second relay.
START DEFROST (iF=dF)
It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will restart only if the digital input is disabled otherwise the instrument will wait until the “dd” safety time is expired.
INVERSION OF THE KIND OF ACTION: HEATING - COOLING (iF=Hc)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
9. INST ALLA TION AND MOUNTING
Instrument XR03CX and XR04CX shall be mounted on vertical panel, in a 29x71 mm hole, and fixed using the special bracket supplied. The temperature range allowed for correct operation is 0÷60 °C. Avoid places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. Let air circulate by the cooling holes.
10. ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up to 2,5
2
mm
. Before connecting cables make sure the power supply complies with the instrument’s requirements. Separate the probe cables from the power supply cables, from the outputs and the power connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads use a suitable external relay.
1.1 PROBES
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is recommended to place the thermostat probe away from air streams to correctly measure the average room temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters or from the warmest place during defrost, to prevent premature defrost termination.
