INSTALLATION

SELECTING A LOCATION FOR YOUR NEW UNIT
The following conditions should be considered when selecting a location for your unit:

1. Floor Load: The area on which the unit will rest must be level, free of vibration, and suitably strong enough to support the combined weights of the unit plus the maximum product load weight. All casters or legs must in contact with the floor. Adjust legs or add shims to casters for uneven floor surfaces. NOTE: Randell’s Low Profile Equipment Stands are designed to support the weight of standard cooking equipment, such as griddles, fryers, and cook top ranges. For non-standard cooking equipment or if there is a question pertaining to weight load limits, consult the factory at 1-888-994-7636.
2. Clearance: There must be a combined total of at least 3” clearance on all sides of the unit. A minimum of 4” clearance is required between cooking appliance and equipment stand.
3. Ventilation: The air cooled self contained unit requires a sufficient amount of cool clean air. Avoid surrounding your equipment stand around other heat generating equipment and out of direct sunlight. Also, avoid locating in an unheated room or where the room temperature may drop below 70°F (21°C) or above 86°F (32°C).

INSTALLATION CHECKLIST

WARNING: FAILURE TO FOLLOW INSTALLATION GUIDELINES AND RECOMMENDATIONS MAY VOID THE WARRANTY ON YOUR UNIT.

After the final location has been determined, refer to the following checklist prior to start-up:

1. Check all exposed refrigeration lines to ensure that they are not kinked, dented, or rubbing together.
2. Check that the condenser and evaporator fans rotate freely without striking any stationary members.
3. Unit must be properly leveled; check all legs or casters to ensure they all are in contact with the floor while maintaining a level work surface. Adjusting bullet feet heights or shimming casters may be necessary if the floor is not level. NOTE: Damage to equipment may result if not followed. Unified Brands is not responsible for damage to equipment if improperly installed.
4. Plug in unit and turn on main on/off power switch.
5. Allow unit time to cool down to temperature. If temperature adjustments are required, the temperature control is located within the cabinet on the front face of the evaporator coil behind the thermometer (Note: The left set of drawers or center set for a 6 drawer unit must be removed to access the temperature adjustment control).
6. Refer to the front of this manual for serial number location. Please record this information in your manual on page 3 now. It will be necessary when ordering replacement parts or requesting warranty service.
7. Confirm that the unit is holding temperature. Set controls to desired temperature for your particular ambient and altitude.
8. Allow your unit to operate for approximately 2 hours before putting in food to allow interior of unit to cool down to storage temperature. NOTE: All motors are oiled and sealed.

ELECTRICAL SUPPLY

WARNING
IT IS IMPORTANT THAT A VOLTAGE READING BE MADE AT THE COMPRESSOR MOTOR ELECTRICAL CONNECTIONS, WHILE THE UNIT IS IN OPERATION TO VERIFY THE CORRECT VOLTAGE REQUIRED BY THE COMPRESSOR IS BEING SUPPLIED. LOW OR HIGH VOLTAGE CAN DETRIMENTALLY AFFECT OPERATION AND THEREBY VOID ITS WARRANTY.
IT IS IMPORTANT THAT YOUR UNIT HAS ITS OWN DEDICATED LINE. CONDENSING UNITS ARE DESIGNED TO OPERATE WITH A VOLTAGE FLUCTUATION OF PLUS OR MINUS 10% OF THE VOLTAGE INDICATED ON THE UNIT DATA TAG. BURN OUT OF A CONDENSING UNIT DUE TO EXCEEDING VOLTAGE LIMITS WILL VOID THE WARRANTY.

The wiring should be done by a qualified electrician in accordance with local electrical codes. A properly wired and grounded outlet will assure proper operation. Please consult the data tag attached to the compressor to ascertain the correct electrical requirements. Supply voltage and amperage requirements are located on the serial number tag located inside the mechanical housing.

OPERATION

MECHANICAL COMPARTMENT

WARNING: EVEN THOUGH YOUR EQUIPMENT STAND WAS DESIGNED FOR HEAVY USE, EXCESSIVE DRAWER OPENINGS SHOULD BE AVOIDED IN ORDER TO MAINTAIN PROPER CABINET TEMPERATURE AND ELIMINATE THE POSSIBILITY OF COIL FREEZE-UP.

Randell has attempted to preset the cold controls to ensure that your unit runs at an optimum temperature, but due to varying ambient conditions, including elevation, food product as well as type of operation, you may need to alter this temperature.
It is strongly recommended that the drawers be kept closed when the unit is not in use and between rush periods. This is especially important in the summer and in kitchens exceeding 86°F. Do not leave the drawers open for prolonged periods of time.

TEMPERATURE CONTROL
Your equipment stand was equipped with a temperature adjustment control located within the cabinet on the front face of the evaporator coil behind the thermometer (Note: The left set of drawers or center set for a 6 drawer unit must be removed to access the temperature adjustment control).
To adjust the temperature in refrigerated units:

1. To lower the temperature:

2. Turn the dial knob clockwise.

3. There are numbers to indicate settings. Keep the arrow on the knob pointed within the numbered section of the arc.

4. Turning it clockwise beyond the numbered section can result in freeze-up.

5. To raise the temperature:

6. Turn the dial knob counterclockwise.

7. There are numbers to indicate settings. Keep the arrow on the knob pointed within the numbered section of the arc.

8. Turning it counterclockwise beyond the numbered section will shut the compressor off.
   NOTE: It is not recommended to turn the dial above 8 or below 1 on the temperature control. If the adjustments still do not result in proper temperature please contact the factory at 1-888-994-7636.

9. If your temperature control is at the maximum setting and the cabinet temperature still remains too low or too high, you may need to adjust the pressure control.

10. Turn the right adjustment screw clockwise (1/4 turn at a time) to a lower number for a colder temperature.

11. Turn the right adjustment screw counterclockwise (1/4 turn at a time) to a higher number for a warmer temperature.

NOTE: Numbers on pressure control are pounds of pressure, not degrees F. NOTE: Do not adjust the differential screw.

DRAWER REMOVAL

1. Fully extend the drawer that is to be removed.
2. Remove product pans from drawer.
3. Lift up the drawer stop tabs on each side of drawer track.
4. Pull drawer out while lifting the tabs.

DRAWER INSTALLATION
To remove and re-install individual drawers and drawer tracks, please refer to the figure above for proper installation instructions.

DRAWER CARTRIDGE SYSTEM REMOVAL
Drawer cartridge system has a single plate in rear to hold in place. To remove the entire drawer system, unscrew the thumb screws on rear wall to detach system from the plate. See figures below.

MAINTENANCE

WARNING
