INITIAL SET-UP

The Model RD-8 and RD-2 Refrigerated Showcase, when properly installed and maintained, is designed to
provide years of trouble-free operation. This Operation Manual contains information necessary for proper
installation, maintenance and cleaning of the unit.

It is the responsibility of the installer to ensure the unit is installed and working properly. The following
instructions provide step-by-step set-up, piping, condensate drain connections, wiring, start-up, performance
and maintenance guidelines.

Following installation, please review, fill out and sign form for activation of warranty within 5 days of
installation. FAX: [phone] or email: [email protected]

CABINET SET-UP

Step 1: Choose a location for your new refrigerated display case. Avoid placing the cabinet near equipment that

releases heat. Avoid direct sunlight. To protect all electrical parts, do not place the cabinet where it

will be subjected to rain, splashed liquid, or excessive humidity. Place unit at least 12” away from the

rear wall.
Step 2: Check the airflow around the cabinet, since strong airflow may displace the cooled air in the display

case. Place the cabinet where the airflow speed is less than 60 ft/min. Also, avoid areas subject to

strong winds or cigarette smoke (see figures 1-9).

CONDENSATE DRAIN CONNECTION (PREFERRED METHOD)

Install the appropriate condensate drain line between the 1 ¼” copper tube outlet to either a floor sink, a drain
line or other, allowing a code required air gap.

9

CONDENSATE REMOVAL METHODS (ALTERNATE)

HEATED CONDENSATE PAN

Heated condensate pan, when used, is
recommended to be placed behind the
unit and not inside the compressor
compartment.

CONDENSATE PUMP

Condensate pumps, when used, can be
placed inside the compressor
compartment or behind the unit with the
outlet connected to the nearest drain.

CABINET ELECTRICAL WIRING

Step 1: Ensure proper voltage input, minimum 210VAC 60Hz maximum 253VAC 60Hz.
If voltage is below the 210VAC or above 253VAC, a BUCK and BOOST transformer is required.

Step 2: Remove the lower-rear and left-side compressor access panel.
Step 3: Remove the left-side junction-box panel and locate the electrical wiring diagram on

the inside of the panel.
Step 4: Install permanently connected field wiring to the 230V/ 60Hz/ 1 Phase (4-wire) compressor circuit.

The pigtail wires are provided. See the circuit amperage ratings located on the unit nameplate.

START-UP & OPERATING INFORMATION

START-UP INFORMATION AND PERFORMANCE EVALUATION

Step 1: Open the front panel and flip the toggle switch to the “ON” position for both left and right side unit.

Both the condensing unit, and the evaporator fans should operate, and the fluorescent lighting should

turn on.
Step 2: While the condensing unit and evaporator fans are running, verify that there is a flow of cold air from

the honeycomb, at the top of the cabinet for each left and right side unit.
Step 3: Observing the controller in the upper-left corner, monitor the cabinet temperature, and verify that both

left and right side unit cools to 40°F within 20-30 minutes.
Step 4: Continue to monitor temperature performance through the complete run cycle, until the system enters

the defrost cycle. The defrost cycle (condensing unit shutdown) is programmed to run for 10 ~ 30

minutes every two hours.
Step 5: Verify that all unit access-cover panels have been replaced, and the cabinet is ready to be loaded by

store personnel.

OPERATING GUIDELINES

1. For best results, pre-cool all product before stocking the display case.

2. Stock products only after the cabinet is cooled.

3. When loading the cabinet, do not place merchandise outside of the shaded area.

4. Allow at least 1” between the upper surface of the displayed product and the shelf directly above it.

5. Do not overload product. Improper loading of merchandise may result in refrigeration inefficiency.

6. Do not remove the glass side panels during operation.

7. Do not stock the shelves with all bottles or cans. Hard or heavy merchandises should not be loaded on

the glass shelves.

GENERAL MAINTENANCE

CLEANING THE HONEYCOMB

In order to maintain peak operating performance, remove the honeycomb (as shown below) and rinse it with
clean water to remove dust. Under normal conditions, inspect and clean every 30 days.

CLEANING THE BOTTOM OF THE INNER BOX & DRAIN

Lift the fan duct, as shown below, and clean the bottom of the inner box with a mild detergent and a soft, damp
cloth. Check the drain hole for proper water flow and remove any blockage. Rinse with clean water.

CLEANING THE CABINET

To clean the cabinet and shelves, use a mild detergent and a soft, damp cloth. Rinse with clean water. Do not
use paint thinner, laundry detergent, or harsh chemicals.

LIGHTING

Power must be turned OFF prior to servicing fluorescent bulbs. Failure to switch power OFF will
damage the ballast.

Replace inoperable fluorescent lights.

14

PRECAUTIONS

CAUTION: Do not operate the unit with the access panels removed.

STORING THE CABINET

Step 1: Disconnect the unit from its power source.
Step 1: Wipe the interior of the cabinet with a damp cloth.
Step 1: Polish the interior of the cabinet with a dry cloth.
Step 1: Store the unit in a clean, dry place. Do not choose a location where the unit will be exposed to direct

sunlight, high temperature, or high humidity.

TROUBLE SHOOTING

Before calling your serviceman, please make these simple checks:

If the unit is not operating:

1. Is the cabinet plugged in?

2. Is there a main-power failure?

3. Is there a blown fuse?

4. Has the refrigeration unit cycled off, because it is at the designated operating temperature?

Note: The evaporator fan motors run continuously and do not cycle with the refrigeration unit.

If the fluorescent light is off:

1. Is the fluorescent-light tube properly connected to the socket?

2. Does the fluorescent light need to be changed?

If the cabinet temperature is too warm:

1. Is the controler set correctly?

2. Is the cabinet located in direct sunlight?

3. Is the cabinet located in a strong air-flow path?

4. Is the distance between the upper surface of the displayed merchandise and the shelf directly above it at

least 1”?

5. Is the air temperature around the cabinet above 75°F?

Reasons for high pressure trips:

1. Overcharge or Non-condensibles.

2. Dirty condenser.

3. TXV sensor bulb loose or powerhead defective.

4. TXV sensor bulb poorly insulated.

REFER TO THE ENVIRONMENTAL CONSIDERATIONS, ON PAGES 5 THROUGH 7,
THAT WILL AFFECT COOLING PERFORMANCE.

Wiring Diagram (buck and boost model number Square D 500SV43B)

Measure line voltage; if line voltage is less than 210V, use buck and boost per instructions below.

1. Connect line voltage supply (LV) side to H1 and H4/X1 terminal.

2. Measure output voltage between terminals H1 and X4. Do not connect to unit if voltage exceeds

253V.

3. Connect load side or unit side to H1 and X4 terminals.
