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

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.

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.

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.

id Interval between defrost cycles: (0÷99 ore) Determines the time interval between the
beginning of two defrost cycles.
Md Maximum length for defrost: (0÷99 min. with 0 no defrost) when P2=n, (not evaporator probe:
timed defrost) it sets the defrost duration, when P2 = y (defrost end based on temperature) it sets
the maximum length for defrost.
dd Start defrost delay: ( 0÷99min) This is useful when different defrost start times are necessary to
avoid overloading the plant.
dF Display during defrost: (rt / it / St / dF) rt= real temperature; it= start defrost temperature; SP=
SET-POINT; dF= label dF.
dt Drip time: (0÷99 min) time interval between reaching defrost termination temperature and the
restoring of the control’s normal operation. This time allows the evaporator to eliminate water
drops that might have formed due to defrost.
dP Defrost at power –on: (y÷n) y= at power on defrost starts; n= defrost doesn’t start at power-on
ALARMS
AU Maximum temperature alarm: (AL÷99°C) when this temperature is reached the alarm is
enabled, after the “Ad” delay time.
AL Minimum temperature alarm: (-55÷AU°C) when this temperature is reached the alarm is
enabled, after the “Ad” delay time.
Ad Temperature alarm delay: (0÷99 min) time interval between the detect ion of an alarm conditi on
and alarm signalling.
dA Exclusion of temperature alarm at startup: (0÷99 min) time interval between the detection of
the temperature alarm condition after instrument power on and alarm signalling.
tb Silencing buzzer (n-y):(Only XR03CX)n= silencing disabled, alarm relay stays on till alarm
conditions lasts; y= silencing enabled: alarm relay is switched OFF by pressing a key during an
alarm;
AP Alarm relay polarity (cL-OP): (Only XR03CX) cL= when active is closed; OP= when active is
opened
DIGITAL INPUT (Only XR03CX)
iP Digital input polarity: (oP ÷ cL) oP= activated by closing the contact; cL= activated by openi ng
the contact;
iF Digital input configuration: (EA/bA/do/dF/Au/Hc) EA= external alarm: “EA” message is
displayed; bA= serious alarm “CA” message is displayed; do= door switch function; dF= defrost
activation; Au =not used; Hc= inversion of the kind of action;
di Digital input delay: (0÷99 min) with iF=EA or bA delay between the detection of the external
alarm condition and its signalling. . With iF=do it represents the delay to activate the door open
alarm.
dC Compressor and fan status when open door: (no/Fn/cP/Fc): no= normal; Fn = Fans OFF; cP
=Compressor OFF; Fc = Compressor and fans OFF;
rdRegulation with door open: (n÷y) n = no regulation if door is opened; Y= when di is elapsed
regulation restarts even if door open alarm is present;
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.
