Installation

SELECTING A LOCATION FOR YOUR NEW UNIT

The following conditions should be considered when selecting a location for your unit:

1. 

Floor and Countertop 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.

2. 

Clearance

:  Clearance must be a combined total of at least 1” on back of unit. 

Do not place any object that can block the ventilation exhaust from the machine 

compartment register. Area of equipment must be free of all combustible materials.

3. 

Ventilation

:  The air cooled self contained unit requires a sufficient amount of cool 

clean air.  Avoid surrounding your unit 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 55°F or rise above 100°F.  

INSTALLATION CHECKLIST

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 button on the controller.

5.  Allow unit time to cool down to temperature. If temperature adjustments are required, 

the control is located on the front panel.  Confirm that the unit is holding the desired 

temperature. 

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 control to desired temperature for 

your particular ambient and altitude.

8.  Before putting in product, allow your unit to operate for approximately two (2) hours 

so that interior of the unit is cooled down to storage temperature.

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.
