adjustments, clogged drains and unit leveling.

2. Randell does not cover gaskets under warranty. Gaskets are a
maintenance type component that are subject to daily wear and tear
and are the responsibility of the owner of the equipment. Because of
the unlimited number of customer related circumstances that can cause
gasket failure all gasket replacement issues are considered non­warranty. Randell recommends thorough cleaning of gaskets on a
weekly basis with a mild dish soap and warm water. With proper care
Randell gaskets can last up to two years, at which time we recommend
replacement of all gaskets on the equipment for the best possible
performance.

considered invalid in the absence of a written quotation. Written quotations
from Randell are valid for 30 days from quote date unless otherwise specified.
Randell assumes no liability for dealer quotations to end-users.

SPECIFICATION & PRODUCT DESIGN

Due to continued product improvement, specification and product design may
change without notice. Such revisions do not entitle the buyer to additions.
Changes or replacements for previously purchased equipment.

SANITATION REQUIREMENTS
Certain areas require specific annotation requirements other than N.S.F. &
U.L. standards. Randell must be advised of these specifications before

STORAGE CHARGES

Randell makes every effort to consistently meet our customer’s shipment
expectations. If after the equipment has been fabricated, the customer
requests delay in shipment, and warehousing is required:

1. Equipment held for shipment at purchasers request for a period of 30
days beyond original delivery date specified will be invoiced and
become immediately payable.

2. Equipment held beyond 30 days after the original delivery date
specified will also include storage charges.

SHIPPING & DELIVERY

Randell will attempt to comply with any shipping, routing or carrier request
designated by dealer, but reserves the right to ship merchandise via any
responsible carrier at the time equipment is ready for shipment. Randell will
not be held responsible for any carrier rate differences; rate differences are
entirely between the carrier and purchaser. Point of shipping shall be
determined by Randell (Weidman, MI/Tucson, AZ/Jackson, MS). At dealer’s
request, Randell will endeavor whenever practical to meet dealer’s request.
Freight charges to be collect unless otherwise noted.

DAMAGES

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
delivery receipt is signed. Claims for damages must be filed immediately
(within 10 days) by the consignee with the freight carrier and all cartons and
merchandise must be retained for inspection.

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

2. Clearance: Clearance for opening the drawer and access to its

contents is the only requirements. 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 90° 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.

followed. Randell 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 front panel next to the digital control

5. Allow unit time to cool down to temperature. If temperature adjustments
are required, the temperature 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. Before putting in food, allow your unit to operate for approximately (1)
hour so that interior of the unit is cooled 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.

NOTE: Damage to equipment may result if not

Unit Installation con’t

ELECTRICAL SUPPLY: Any 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.

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.

NOTE: 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.

FX-1 (2N1) Unit Operation

PRODUCT PLACEMENT AND MAXIMUM LOAD LEVELS

1. This unit’s insulated drawer insert is provided and designed to
hold food products with or without containers.

2. Refrigerated or freezer tempered air is introduced into the
insulated drawer insert from above and circulates around the
product for even temperature distribution.

3. For the unit to operate at full efficiency the drawer seals
should be maintained in good condition. It is essential that
product is not stored above the Max Fill line as this can
damage the seals and affect the operation of the unit.

4. This unit is designed for holding products at temperatures -5°F
to 40°F. Products placed in unit should be pre-chilled to the
holding temperature. This unit is not intended for use as a pull
down cabinet.

5. The unit is capable of storing any food product. However,
products which may give off acidic odors like vinegar, onions,
etc should be suitably sealed. Randell also recommends
containers with liquid food products be stored with lids.

6. The drawer system is designed for easy unobstructed access to
the product in the insulated drawer insert. The track should run
smoothly with little resistance during the motion of opening and
closing the drawer. The drawer will have more resistance when
the unit is warm and not operating in either the refrigeration or
freezer mode, this is normal as the gasket will contract slightly
when the unit is cooling and allow smooth travel of the drawer.

AMBIENT CONDITIONS

1. This unit is designed for operation in a room ambient of 86°F / 55% relative humidity. It should
never be used outside or located in direct sunlight.

Randell 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.

Your FX-1 (2N1) Series Unit is equipped with an
electronic temperature control. Figure 1, left, illustrates
the Dixell XR60C control location on the front above the

FX-1 (2N1) Control Operation

Figure 1

, left, illustrates an alternate electronic

temperature control, Dixell XR60CX with blue LED.

Before making temperature adjustments:

A. Allow adequate time for the cabinet temperature to equalize. When initially started or when

first loaded, it can take a long time for temperatures in the display area to stabilize.

B. Make sure that unit operation is not being effected by room ambient conditions. (See Ambient

Conditions section above). If there are any significant ambient issues, adjusting the temperature
setting may not help.

To raise temperature:

A. Push and hold the “SET” button until set point 33 appears then release the “SET” button.

33 is the current set point temperature.

B. Push and release the up arrow 1 or more times until the desired temperature is displayed.

Push and release the “SET” button one time. The new set point will flash 3 times and then
will be locked in.

To lower temperature:

A. Push and hold the “SET” button until 33 appears and then release the “SET” button. 33 is

the current set point temperature.

B. Push and release the up arrow 1 or more times until the desired temperature is displayed.

Push and release the “SET” button one time. The new set point will flash 3 times and then
will be locked in.

NOTE: The FX-1 (2N1) Series Unit is designed to operate in both refrigerated or freezer
mode by adjusting the “SET” point to the desired temperature. The maximum highest
setting is 40°F and the minimum lowest setting is -5°F. If the settings need to go above or
below this point there may be other contributing factors as to the cause of the
temperature variances, please contact the factory at 1-800-621-8560.
