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 3” on all sides and 

back of unit. Do not place any object that can block the ventilation exhaust from 

the machine compartment register.

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 55°F or above 86°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 switch. The main power switch is 

located in the compressor mechanical housing.

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

required, the temperature control is located on the evaporator coil within the 

refrigerated base (refer to page 10).  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 2 now.  It will be necessary when ordering 

replacement parts or requesting warranty service.

7.  Before putting in food, allow your unit to operate for approximately two (2) hours so 

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

8.  Check doors to ensure there is proper sealing and alignment.
9.  For units with self-closing doors:  Check doors to ensure they open and shut freely.
  Note:  All motors are oiled and sealed
  Note:  All self-contained models are shipped from the factory with the service 

valves open and ready for operation.
