B. Maintain support of case at all times or center of gravity may cause case to fall.
C. Unlock Casters. Slide unit to rear of skid. Slide down ramp and off from skid.

INSTALLATION

1. Ventilation and Clearance

It is recommended that Self-Contained refrigerated cases maintain a airflow clearance of approximately 6” at the rear to 12” in the front of the case.
Obstruction or restriction of air can void warranty.

2. Removing Shipping Screws

Plastic glides are mounted to the unit base to assist in sliding the condenser out for access.

• Remove the front grill by removing the screws located in each of the corners.
• Remove the shipping screws located at base of condenser frame.

START-UP AND OPERATION

1. Merchandiser Start-Up – Main Power

• Turn on main power switch located behind the front grille. Main power switch is on left hand side of base. Replace front grille.
  > > Supply power will start evaporator coil fans, **and the compressor motor.**

• From front of case, raise deck pans and check to see that the coil fan is functioning properly.

• Replace front grille by inserting screws in locations provided.

2. Merchandiser Start-Up/Lights

• Turn on the main power. Remove the front grille by removing the screws located in each of the corners. Switch is on the left hand side of base. Supply power will start evaporator coil fans, and the compressor motor. From the front of the case, raise the deck pans and check to see that the coil fans are all functioning properly.
• Replace front grille by inserting screws in locations provided.
• Turn on the lights. Light switch is in the interior of the case. Switch may be above or below the top shelf and to the left or right side [as shown in illustration below]. First time lighting may require a short warm-up period for the bulb. Slightly dim or a flickering of new bulb is normal. If light do not turn on, see TROUBLESHOOTING [TO BE PERFORMED BY STORE PERSONNEL] section in this operating manual.

3. Temperature Settings

• The case temperature is set at the factory, (supply air 25 °F for a case temp of 41 °F), as determined by the case size.
• The temperature is controlled by a thermostat. If a temperature setting change is required, refer to temperature control access.

4. Product Rotation

• To prevent freezing or spoilage of stock, product must be rotated.
• At every re-stocking, rotate old stock to front of shelves and new stock to rear of shelves.

MAINTENANCE: SHELF ASS’Y REMOVAL / LIGHT FIXTURES / BALLAST ACCESS

1. Shelf Assembly Removal

• Shelf can be removed for cleaning or adjustment.
• For lighted shelving, unplug the light cord.
• Lift shelf straight up to separate from brackets.
• Remove brackets.
• Note: Initially, it may be necessary to remove the nylon shipping bracket retainer. Pliers will be required to accomplish this task.

2. Fluorescent Light Fixture

• Fluorescent light fixture is shown at right.
• LED light fixtures are shown on next page.

Removal of lamp:

• Rotate lamp (1/4-turn) so that pins are aligned in slots and remove bulb.

Installation of lamp:

• Align pins with slot.
• Insert pins into socket and rotate 1/4 turn to secure pin contacts in socket.

3. Ballast Access

• Assembly or disassembly and servicing to be accomplished by licensed electrical contractors only.
• Remove the front grille by lifting up and off.
• Refrigerant lines are flexible to facilitate maintenance. However, use caution to avoid crimping or kinking copper tubing while sliding condenser unit out from under case!
• Plastic glides are mounted to the unit base to assist in sliding the condenser out for access.
• Remove shipping retaining screws.
• Slide condenser unit forward approximately twelve inches to access the light ballast.
• Ballast is located on the left side of the condenser in electrical box. See illustration

MAINTENANCE, CONT’D: LED STYLE LIGHT FIXTURE COMPONENT REMOVAL &

REPLACEMENT

4. LED Style Light Fixture Component R &R

Removal of Faulty LED Lights or Other Components:

• LED lights and/or other LED related components rarely require replacement.
• If replacement parts are needed, Contact Structural Concepts’ Technical Service Department for parts.
• Turn off LED light switch.
• To remove faulty LED light (or other components), follow these steps:
  A. Disconnect plug from LED light.
  B. Using both hands, grasp LED light assembly (with its magnetic mounting clips). Pull downward and off shelf (or header).
  C. If mounting clips are riveted to shelf or header, simply remove LED light from mounting clips by pressing against flange part of clips with thumb while pulling downward on LED light.

Replacement of LED Lights or Other Components:

• Attach magnetic mounting clips onto LED light (if they are not riveted to shelf or header).
• Adjust magnetic mounting clips so they are equally spaced on LED light.
• Reattach LED light assembly to its shelf/header. If mounting clips are riveted to shelf or header, simply remove LED light from mounting clips by pressing against flange part of clips with thumb while pulling downward on LED light..
• Press plug’s barrel-shaped insert all the way into LED light.
• Important: If plug is not inserted ALL THE WAY IN the LED light’s orifice, the light may not energize. See “BAD” vs. “GOOD” insertion illustrations below-right.
• Turn LED light switch back on.

MAINTENANCE, CONT’D: HONEYCOMB AIR DIFFUSERS

5. Honeycomb Air Diffusers

Note: Preventive maintenance should be performed every 30 days unless conditions warrant a more frequent replacement cycle.

Honeycomb Air Diffuser Removal

Honeycomb is located in discharge air duct.

A. Wedge a non-metallic device of suitable strength (such as a ballpoint pen) between the honeycomb and the end panel.

Caution! Use care not to dislodge the heating wire (that prevents condensation on the lamp assembly).

B. Apply pressure to collapse the honeycomb to allow it to be pulled out of honeycomb retainer.
C. Pry downward and away from honeycomb retainer.

• Clean honeycomb with warm water and soap solution.
• Submerse if necessary.
• Use brush to dislodge stubborn or sticky residue.
• Dry by using vacuum’s blow mode (vs. suction mode).

Honeycomb Air Diffuser Installation

D. Squeeze honeycomb to allow it to fit into honeycomb retainer.
E. Carefully slide honeycomb into place.
F. Adjust honeycomb so that it fits flat against retainer.
It must not be wavy or out of position.

Note: For honeycomb air diffusers in other locations, these same general instructions apply.
