PARTS WARRANTY
1. One year parts replacement of any and all parts that are found defective in
material or workmanship. Randell warrants all component parts of
manufactured new equipment to be free of defects in material or workmanship,
and that the equipment meets or exceeds reasonable industry standards of
performance for a period of one year from the date of shipment from any
Randell factory, assembly plant or warehouse facility.
NOTE: warranties are effective from date of shipment, with a thirty day
window to allow for shipment, installation and set-up. In the event
equipment was shipped to a site other than the final installation site,
Randell will warranty for a period of three months following installation,
with proof of starting date, up to a maximum of fifteen months from the
date of purchase.
2. Free ground freight of customer specified location for all in warranty parts
within continental U.S. Component part warranty does not cover glass
breakage or gasket replacement. Randell covers all shipping cost related to

In the unlikely event a Randell manufactured unit fails due to defects in
materials or workmanship within the first ninety days, Randell agrees to pay
the contracted labor rate performed by an Authorized Service Agent (ASA).
Any warranty work performed by a non-ASA will not be honored by Randell. A
complete listing of current ASAs can be found on the Randell page of our web
site : www.unifiedbrands.net. Warranties are effective from date of shipment,
with a thirty day window to allow for shipment, installation and setup. Where

defective unit be sent back to Randell freight prepaid. Perform repair at
the expense of Randell and ship the item back to the customer freight
collect.

All crating conforms to general motor carrier specifications. To avoid
concealed damage, we recommend inspection of every carton upon receipt.
In the event the item shows rough handling or visible damage to minimize
liability, a full inspection is necessary upon arrival. Appearance of damage will
require removing the crate in the presence of the driver. A notation must be
placed on the freight bill and signed for by the truck driver at the time of
delivery. Any and all freight damage that occurs to a Randell piece of
equipment as a result of carrier handling is not considered under warranty, and
is not covered under warranty guidelines. Any freight damage incurred during
shipping needs to have a freight claim filed by the receiver with the shipping
carrier. Consignee is responsible for filing of freight claims when a clear

(within 10 days) by the consignee with the freight carrier and all cartons and
merchandise must be retained for inspection.

any merchandise. Any returned goods shipment lacking the return
authorization number will be refused, all additional freight costs to be borne by
the returning party. Returned equipment must be shipped in original carton,
freight prepaid and received in good conditions. Any returned merchandise is
subject to a minimum handling charge (consult factory for rate).

Equipment installation is the responsibility of the dealer and/or their customer.
Randell requires all equipment to be professionally installed to ensure
adequate voltage and amperage requirements are met.

Unit 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 must be
in contact with the floor to support the weight. Casters may require
shims in orderfor the caster to be in contact with the floor.
NOTE: If there is a question pertaining to weight load limits, consult the
factory at 1-800-621-8560.
2. Ventilation: The air cooled self contained unit requires a sufficient
amount of cool clean air. Also, avoid locating in an unheated room or
where the room temperature may drop below 55°F (13°C) or about
86°F (32°C).
INSTALLATION CHECKLIST
After the final location has been determined, refer to the following checklist prior to
start-up:
1. Check all visible componentsfor any potential damage
2. Check that the condenser and evaporator fans rotate freely without
striking any stationary members.
3. Check all doors for proper alignment and seal.
4. Power up unit once plugged in.
5. Allow unit time to cool down to holding 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.
8. Allow your unit to operate for approximately 45 minutes before putting
in food to allow interior of unit to cool down to storage temperature.
NOTE: All motors are oiled and sealed.
NOTE: FAILURE TO FOLLOW INSTALLATION GUIDELINES AND
RECOMMENDATIONS MAY VOID THE WARRANTY ON YOUR UNIT.
ELECTRICAL SUPPLY: 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 locatedon the serial number tag located on the rear interior wall. .
NOTE: 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.

Unit Operation
Randell has 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.
Additional adjustments can be made (within limits) by turning the control dial up or
down until the desired temperature is reached. Please allow 24 hours between
adjustments.
Your condiment pans will remain proper temperatures when utilized properly. It is
strongly recommended that the covers be kept in closed position when the unit is
not in use and between rush periods. This is especially important in the summer
months and in kitchens exceeding 86°F. Do not leave covers open for prolonged
periods of time.
Note: All individual condiment pans need to be in the rail at all times during
operation. If no product is available or necessary fill empty pans with 1” to 2”
of water as an insulating barrier.
Note: Even though your DPM series was designed for heavy use, excessive
door openings should be avoided in order to maintain proper box
temperature and eliminate the possibility of coil freeze up.
Your DPM series preparation table was equipped with a temperature adjustment
control for the refrigerated rail (Figure 1). This is found behind the hinged door of
the mechanical compressor housing. There is also a temperature adjustment
control for the refrigerated base (Figure 2), which is located on the front exterior of
the evaporator blower coil inside the lower cabinet.
Figure 1 illustrates the electrical control box inside the mechanical compartment. The on/off switch for
the rail is located on the frontof the control box while the main on/off switch for the entire unit is located
on the rear of the control box. The thermostat adjustment knob for the upper rail is located on the side
of the control box. (This thermostat also controls the refrigerated catch pan area).
