111 ■ STORAGE SUGGESTIONS
-
IMPORTANT: If possible, store the unlt(s) with all packaging Intact In a weather proof enclosure.
Do Not expose the units to extreme high or low temperatures, excessive humidity, or dusty
conditions. Store units UPRIGHT on a level surface.
IV. INSTALLATION
NOTE: The instaHation instructions are similar for both the R71 THKD single bay unit and the
R72THKD double bay unit.
A. LOCATION REQUIREMENTS
1. To ensure optimum performance the top of all units MUST HAVE A MINIMUM 12" CLEARANCE ABOVE
THE UNIT. The 12" overhead clearance is also necessary to access the unitshould servicing be
required. (This is required for the front panel to swing up).
THE MINIMUM FINISHED FLOOR TO CEILING HEIGHT REQUIRED FOR PROPER OPERATION OF THE
RETHERMALIZATION REFRIGERATORS IS 96".
2. The normal temperature of the room where the rethermalization refrigerators are placed must not
exceed 90°F (32.2°C) for the units to operate properly.
B. MOVING THE UNIT THROUGH DOORWAYS
The doors hinges and top fascia should be·removed if location doorways are 34' (86.4cm) or narrower.
C. REMOVAL OF DOORS, HARDWARE & TOP FASCIA
CAUTION
1. Each door weighs approximately 72 lbs, (32.7 kg). Utmost care should be taken whenever the
door is lifted off its hinges. ATTENTION: lfmore than one unit is being moved, care should be taken
when doors are re-installed. DOORS MUST BE RETURNED TO THE SAME UNIT THEY WERE REMOVED FROM.
2. The doors on the units feature lift-offself-closing hinges. Open door to a full 180 degrees and liftupward.

3. Removal of the hinges from the cabinet body is not recommended. If it becomes
necessary to remove the hinges, mark hinge location prior to removal from the cabinet
to ensure proper door re-alignment.
4. Removal of top fascia. If it is necessary to remove the top fascia, disconnect polarized
wire connectors from the back of the MAGIC TOUCH CONTROLLER before removing
the front lift up panel. Remove the stainless steel fascia from the condensing unit area
to reduce overall height of unit. Reassemble fascia and MAGIC TOUCH CONTROLLER.
NOTE: When reconnecting the Magic Touch Controller, be sure that the 11 pin connector is in
the "A" side, not the "D" side. To check that the connections are correct, press the view button
3 times. If80 volts is displayed, check connections again.
D. SETTING THE UNIT IN PLACE
1. ATTENTION: The unitshould remain on its skid during movement to the point of installation
to prevent damage to bottom of unit.
2. CAUTION: The single unitweighs 693 lbs. (3l4.34kg.)and the double unit weighs l019 lbs.
(462.kg.) Extreme Care must be taken wheneverthe unit is moved ortilted to remove the skid.
3. The unit rests on the skid and is not secured by bolts. The removal from the skid requires
several people to slowly slide the unit off the skid. Avoid tilting the unit when removing if
from the skid. CAUTION: If if was necessary to tilt the unit during installation, if must not be
plugged in for a period of 24 hours after being set in place.
E. LEVELING
1. Units must be level within l/8" (3.18mm) to ensure proper door closure. Level installation is
critical for the double door units. If problems are encountered when closing the doors,
bottom door seal is binding, or door locks are not engaging properly, the unit is most likely
not level.
2. If the unit is more than l/8" (3.18mm) out of level, the unitshould be shimmed. The
recommended shim material is 12" x 12" (30.5cm) vinyl floortile.
3. EXAMPLE: If the right hand end of the double door unit is about l/4"(6.35mm) low, due to
flooring inconsistencies, use a pry bar to lift the low end, then slide a full tile under that end
as far as possible. If necessary, take a second tile to push the piece as far under the unit as
possible. Cut off any tile extending outside the cabinet body. Add a second layer and a
third, if necessary, until the unit is level. Be sure to trim off any tile projecting out from the
sides of the unit. The obiective is to supportthe entire bottom of the refrigerator so that the
unitfloorwill not sag with use.

F. RAMP INSTALLATION
A stainless steel ramp is shipped with the units. The front edge of the refrigerator interiorfloor
has stainless steel shoulder bolts to receive and secure the entry ramp. Simply position the slots
on the ramp over the shoulder bolts and lower the ramp into position. This ramp can be easily
removed for cleaning by reversing the installation steps.
V ■ ELECTRICAL
1. ELECTRICAL REQUIREMENTS
R71THKD (single unit): 208-240v*/120v/4w, 60 Cycle, Single Phase, 45 Amp maximum over
current protection.
R72THKD (double unit): 208-240v*/120v/4w, 60 Cycle, Single Phase, 60 Amp maximum over
current protection.
NOTE: The roll-in refrigerators areset-up for 208-240v*/120v/4w power supply. If a 240v
application is necessary see following
* 240 Volt Service
For 240v service a field wiring change must be performed. A qualified electrician is required
for this modification. This modification is a one step procedure: A NEUTRAL wire must be
connected from the panel to the capped BLACK WIRE w/ blue label on the boosttrans-
former. Consult wiring diagram for the location of the boosttransformer.
NOTE: All factory wiring has been made in compliance with electrical codes and UL
requirements.
WARNING: All installation electrical and grounding connections must comply with the
applicable portions of the National Electrical Code and/or all local electrical codes.
A qualified electrician should make allrequired installation connections. ConsuN wiring
diagram provided.
2. ELECTRICAL CONNECTION
A breaker panel/load center with circuit breakers is provided forfield connections. This panel
is marked FIELD CONNECTION and should be the only panel entered intofor electrical
connection during installation.
A separate electrical circuit should be used when installing the roll-in refrigerators. Size wiring
to handle the indicated load and provide the necessary overcurrent circuit protection.

RETHERMALIZATION REFRIGERATORS
WARNING: When making electrical connections, it is mandatory that the Incoming neutral line
be laid down on a neutral bus. If a hot leg is connected to a neutral bus, 208 or 240 volts will
be across the 120 volttransformer and will destroy the primaryside of the transformer.
RECOMMENDATION: Check the supply voltage prior to connection to be certain the proper
voltage for the unit Is available. Check the serial nameplate inside unitfor correct voltage.
VI ■ START-UP

1. DEFROST CYCLE
Set the current time on the Paragon clock. Set defrost cycle on Paragon clock for four (4)20 minute
defrostcycles per day. Clocksetting instructions are inside the clock cover.
NOTE: Defrost cycles are factory set for 12AM, 2PM, 10PM, and 4AM Central Time. If a defrost time
schedule change is required, it can be changed. Follow the instructions located inside the
defrosttimercover. DO NOT SET THE DEFROST TIME DURING SCHEDULED RETHERM CYCLES.
2. MAGIC TOUCH CONTROLLER BATTERY
A standard9 Volt battery is providedfor the Magic Touch Controller. During shipment, this battery is
reversed in the battery harness, so that itwill maintain its charge. Prior to operation the battery(s)
must be installed correctlyfor the controller to function.
R71THKD, Single Bay Unit has (1) one 9V. Battery, R72THKD, Double Bay Unit has (2) two 9V. Batteries
3. STARTING UNIT
CAUnON: Before startingthe unit,make sure theevaporatorfan blades aresecurelyfastened
Lift up the front panel high enough to engage panel support bracket locking mechanism.
Turn power circuitbreakers on.
4. START-UP CHECKS
Check that the compressor is running and the air circulating fans are also functioning. The
compressor will run for approximately one hour, or until the empty cabinet is cooled to a
temperature of 32 °F (0°C).
NOTE: Wait until cabinet temperature stabilizes between 32-40°F (0-4.4°C) before placing cart(s)
loaded with product into the cabinet. Running the unitwith the door closed will cause the
compressor to cycle and maintain the internal cabinet temperature of 32-40°F (0--4.4°C).
