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 and open clearance at the top. 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 70°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. 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.
5. 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.
6. 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.
7. Check drawer to ensure the drawer slides freely and fully extends along with
seating into the cabinet properly when closed.
ELECTRICAL SUPPLY
Any wiring should be done by a qualified electrician in accordance with all
national and 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.
OPERATION
Allow unit to operate for approximately two (2) hours before placing in food.
AMBIENT CONDITIONS
Unit is designed for normal operating temperatures between 70-100°F. Operating
outside of those temperatures may cause premature product wear or failure.
Unified Brands has attempted to preset the temperature control to ensure that
your unit runs at an optimum temperature, but due to varying ambient conditions,
including elevation, food type and your type of operation, you may need to alter
this temperature using control adjustment until desired temperature is reached.
