Electrical Service
DANGER
Check all wiring connections, including factory terminals,
before operation. Connections can become loose during
shipment and installation.
nWarning
This appliance must be grounded and all field wiring must
conform to all applicable local and national codes. Refer
to rating plate for proper voltage. It is the responsibility of
the end user to provide the disconnect means to satisfy
the authority having jurisdiction.
Voltage
All electrical work, including wire routing and grounding,
must conform to local, state and national electrical codes.
The following precautions must be observed:
• The equipment must be grounded.
• A separate fuse/circuit breaker must be provided for each
unit.
• Check all green ground screws, cables and wire
connections to verify they are tight before start-up.
Ground Fault Circuit Interrupter
Ground Fault Circuit Interrupter (GFCI/GFI) protection is a
system that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to ground.
Welbilt does not recommend the use of GFCI/GFI circuit
protection to energize our equipment. If code requires the
use of a GFCI/GFI then you must follow the local code. The
circuit must be dedicated, sized properly and there must
be a panel GFCI/GFI breaker. We do not recommend the
use of GFCI/GFI outlets to energize our equipment as they
are known for more intermittent nuisance trips than panel
breakers.

Drain Connections
All models are standard with a condensate evaporator
located behind the louvered door. It is designed to evaporate
the water which condenses on the base’s mullion coils.
Each Makeline has a drain in the catch pan area and in
the top rail area. These drains manifold together in the
mechanical area and can be drained by one common gate
valve.
nWarning
Moisture collecting from improper drainage can create a
slipper surface on the floor and a hazard to employees.
It is the owner’s responsibility to provide a container or
outlet for drainage.
Leg & Caster Installation
DANGER
Legs or casters must be installed and the legs or casters
must be screwed in completely to prevent bending. When
casters are installed the mass of this unit will allow it to
move uncontrolled on an inclined surface. These units
must be tethered/secured to comply with all applicable
codes.
nWarning
The unit must be installed in a stable condintion with
the front wheels locked. Locking the front casters after
installation is the owner’s and operator’s responsiblity.
Leveling
After the cabinet has been placed in the desired location,
cabinets with legs must be leveled. Level units from front
to back then side to side. Leveling will insure proper door
operation and removal of condensate. Cabinets with casters
must have the caster brake set so the cabinet cannot move.
Stabilizing
It is very important that all legs are properaly adjusted to
keep the cabinet level ,evenly distribute the weight and to
make sure the unit will not rock, lean or be unstable.

Part Number: 9291545 REV00 11/20 11

in this manner.
DANGER
Keep power cord AWAY from HEATED surfaces. DO NOT
immerse power cord in water. DO NOT let power cord
hang over edge of table or counter.
nWarning
Do not contact moving parts.
nWarning
The operator of this equipment is solely responsible
for ensuring safe holding temperature levels for all
food items. Failure to do so could result in unsafe food
products for customers.
nWarning
All covers and access panels must be in place and properly
secured, before operating this equipment.
nWarning
Do not block the supply and return air grills or the air
space around the air grills. Keep plastic wrappings,
paper, labels, etc. from being airborne and lodging in
the grills. Failure to keep the air grills clear will result in
unsatisfactory operation of the system.
nWarning
Damp or wet hands may stick to cold surfaces.
,Caution
Overloading the storage area, restricting the air flow, and
continuous opening and closing of the doors and drawers
will hamper the units ability to maintain operational
temperature.
,Caution
Do not throw items into the storage area. Failure to
heed this recommendation could result in damage to the
interior of the cabinet or to the blower coil.
Make Tables
Delfield refrigerated bases are designed to maintain an
operational temperature of 36°F to 40°F (2°C to 4°C). Self-
contained units with a cord and plug have an ON/OFF switch
located directly behind the louvered panel covering the
compressor section. Simply turn the switch to ON to begin
operation.
Temperature in the rail is designed to maintain 33°F to 41°F
(0°C to 5°C) with pans recessed 2” (5cm) at 86°F (30°C)
ambient room temperature. An ON/OFF switch is also
provided for the rail; it controls only the rail. Turn the rail
switch on an hour before filling with product.
Product in the rail should be moved to the refrigerated base
at the end of the day. The rail is required to be shut off at
night to save energy and time to defrost as needed. It also
helps maintain product quality.
These units are not designed to cool warm food products.
Items should be placed in the unit cooled at least to the
desired holding temperature, if not slightly colder. Fill pan
to 2.0” (5cm) below top of cold pan. In some applications,
a gradual warming of product may occur, particularly at
the exposed top of the products. Stirring or rotation of the
product is necessary to maintain overall temperature.
Warming of food product can occur very quickly outside
of the unit. When loading or rotating the product, avoid
leaving food items in a non-refrigerated location for any
length of time to prevent warming or spoilage. To ensure
product quality product must be rotated every four hours.
Always place covers on pans when not serving to maintain
temperatures.
Air from air vents can affect the temperature in the cold
pans. Add deflectors to vents to redirect airflow.

Operation

Operation Section 3
12 Part Number: 9291545 REV00 11/20
Instructions for Optimal Performance
1. The main switch is located behind the louvered door. It
controls the cabinet and must be in the ON position for
the top rail/catch pan switch to operate. Turn it to the
ON position.
2. The top rail/catch pan switch is located behind the
louvered door. Turn it to the ON position.
3. The drain valve is located behind the louvered door. This
valve controls both the top rail and the catch pan drain
lines. Make sure it is turned OFF.
4. Food product may be placed into the base and the top
rail of the unit after one hour of operation.
• The unit is not designed to lower product
temperature, only to maintain temperature. The food
product must be 41°F (5˚C) or below before placing
into the refrigerator.
• To ensure product quality in the rail it is
recommended that product be rotated every four
hours.
• The catch pan area and the top rail area are designed
to meet the NSF 7 criteria. The design requires a
layer of frost to build up on the wall of the top rail
and catch pan area. This is normal, and also required,
to meet the desired temperatures.
• It is recommended to empty the excess food product
in the catch pans after two hours of use throughout
the work day to achieve the best temperatures.
However, the catch pans are capable of maintaining
temperatures up to four hours if needed.
5. At the end of the operation, the top rail/catch pan
switch must be turned to the OFF position. The cabinet
main switch remains ON. The rail frost will melt and flow
down the drain line.
• Product located in the rails must be removed at the
end of day. This allows you to turn the rails off at
night to save energy and the rails will have time to
defrost as needed. It also helps maintain product
quality. The rail switch shuts off the rail only.
• A minimum of one hour of off time per day with the
pans removed is required to properly defrost the top
rail.
• If pans are left in the top rail, up to four hours may be
required to defrost under the pans.
6. The drain valve should be turned ON to allow for
drainage into a customer provided waste container.
7. The catch pan area and top rail area may be cleaned at
this time. The large 1” diameter drain lines allow water,
cleaning solutions, etc. to flow freely down the drain.
8. At the end of the cleaning procedure, turn the drain
valve to the OFF position.
9. Steps 2 through 8 should be repeated during each work
day.
,Caution
The main unit switch must remain “ON” if product is held
in the refrigerated base.

Section 3 Operation
Part Number: 9291545 REV00 11/20 13
Evaporator Fan Operation
When the refrigerator is initially powered up or immediately
following a power outage the unit will begin cooling after a
3-6 minute delay. During normal operation the evaporator
fan pulses independently of the compressor as dictated by
the controller as follows:
1. During the cooling mode, compressor and evaporator
fan run simultaneously.
2. During the compressor off mode, evaporator fan pulses
three minutes on and three minutes off.
3. During an actual defrost event other than the off-cycle
defrost, compressor stays off but the evaporator fan
runs continuously.

ERC112 Temperature Control
The Maketable control assembly is located behind the
louvered door in the machine compartment.
Maketable Control Assembly
AT START UP
1. At initial start-up or anytime power is disconnected, then
reconnected to the unit, the control will go into defrost
mode.
2. The control will enter a DEFROST mode and the display
will read dEF. The compressor and condenser fan as well
as the evaporator fan will remain off until this initial
defrost is complete. This initial defrost cycle may take up
to 35 minutes to complete.
3. The display will continue to read dEF for an additional 30
minutes while the cooling cycle cools the box to the set
temperature.
4. Then the digital thermostat will display box temperature.
5. The temperature control will cycle the compressor,
evaporator fan motor and condenser fan motor to
maintain box temperature at the control setting. For
more information see “Evaporator Fan Operation” on
page 13.
Defrost
The temperature control also monitors the evaporator
temperature and will turn off the compressor and condenser
fan motor when needed to allow accumulated frost on the
evaporator to clear. During this defrost cycle, the digital
temperature display will read dEF. After the defrost cycle is
complete, the temperature control will return to a normal
cooling cycle, but the display will continue to read dEF until
the evaporator returns to normal cooling temperatures (up
to 30 minutes).
The electronic temperature controller monitors evaporator
temperature and compressor run time to determine the
proper time for a positive defrost cycle. A defrost cycle
can occur as often as every 60 minutes under extremely
heavy usage. It can last a minimum of 2 minutes. When the
controller enters the defrost mode the compressor is shut
off and will remain off until the evaporator coil temperature
exceeds:
• 41°F (5°C) or the controller reaches a time limit of 75
minutes on a refrigerated unit.

DANGER
It is the responsibility of the equipment owner to perform
a Personal Protective Equipment Hazard Assessment
to ensure adequate protection during maintenance
procedures.
DANGER
Failure to disconnect the power at the main power supply
disconnect could result in serious injury or death. The
power switch DOES NOT disconnect all incoming power.
DANGER
Disconnect electric power at the main power disconnect
for all equipment being serviced. Observe correct polarity
of incoming line voltage. Incorrect polarity can lead to
erratic operation.
nWarning
When cleaning interior and exterior of unit, care should
be taken to avoid the front power switch and the rear
power cord. Keep water and/or cleaning solutions away
from these parts.
nWarning
Never use sharp objects or tools to remove ice or frost. Do
not use mechanical devices or other means to accelerate
the defrosting process.
nWarning
When using cleaning fluids or chemicals, rubber gloves
and eye protection (and/or face shield) must be worn.
,Caution
Over shelves and other items mounted to the top of the
counters should never be installed in the field due to the
potential damage to the refrigeration system.
,Caution
Maintenance and servicing work other than cleaning as
described in this manual must be done by an authorized
service personnel.
Notice
Never use a high-pressure water jet for cleaning or hose
down or flood interior or exterior of units with water. Do
not use power cleaning equipment, steel wool, scrapers
or wire brushes on stainless steel or painted surfaces.
Responsibility
You are responsible for maintaining the equipment
in accordance with the instructions in this manual.

Interior Cleaning
The interior can be cleaned using soap and warm water. If
this isn’t sufficient, try ammonia and water or a nonabrasive
liquid cleaner.
GASKETS
Gaskets require regular cleaning to prevent mold and mildew
build up and also to retain the elasticity of the gasket. Clean
them with water and mild soap (not citrus based). Avoid full
strength cleaning products on gaskets as this can cause them
to become brittle and crack. Never use sharp tools or knives
to scrape or clean the gasket. Gaskets can be easily replaced
and do not require the use of tools or an authorized service
person. The gaskets are dart style and can be pulled out of
the groove in the door. Place gasket in warm water to make
the material more pliable for installation. Dry and press into
place.
PREVENTING BLOWER COIL CORROSION
To help prevent corrosion of the blower coil, store all acidic
items, such as pickles and tomatoes, in seal-able containers.
Immediately wipe up all spills.
Exterior Cleaning
Notice
Never use an acid based cleaning solution on exterior
panels! Many food products have an acidic content,
which can deteriorate the finish. Be sure to clean the
stainless steel surfaces of ALL food products.
Clean the area around the unit as often as necessary to
maintain cleanliness and efficient operation.
Wipe surfaces with a damp cloth rinsed in water to remove
dust and dirt from the outside of the unit. Always rub with
the “grain” of the stainless steel to avoid marring the finish.
If a greasy residue persists, use a damp cloth rinsed in a mild
dish soap and water solution. Wipe dry with a clean, soft
cloth.
Never use steel wool or abrasive pads for cleaning. Never use
chlorinated, citrus based or abrasive cleaners.
Stainless steel exterior panels have a clear coating that
is stain resistant and easy to clean. Products containing
abrasives will damage the coating and scratch the panels.
Daily cleaning may be followed by an application of stainless
steel cleaner which will eliminate water spotting and
fingerprints. Early signs of stainless steel breakdown are
small pits and cracks. If this has begun, clean thoroughly and
start to apply stainless steel cleaners in attempt to restore
the steel.
Wipe casters with a damp cloth to prevent corrosion.
DRAIN
Drains can become loose or disconnected during normal use.
Be sure all drain lines are free of obstructions.
Doors
Over time and with heavy-use doors, the hinges may become
loose. If this happens, tighten the screws that mount the
hinge brackets to the frame of the unit. Loose or sagging
doors can cause the hinges to pull out of the frame, which
may damage both the doors and the hinges. In some cases
this may require qualified service agents or maintenance
personnel to perform repairs.
Cleaning The Condenser Coil
In order to maintain proper refrigeration performance, the
condenser fins must be cleaned of dust, dirt and grease
regularly. It is recommended that this be done monthly. If
conditions are such that the condenser is totally blocked
in a month, the frequency of cleaning should be increased.
Clean the condenser with a vacuum cleaner or stiff brush. If
extremely dirty, a commercially available condenser cleaner
may be required.
Failure to maintain a clean condenser coil can initially cause
high temperatures and excessive run times. Continuous
operation with a dirty or clogged condenser coil can result in
compressor failure. Neglecting the condenser coil cleaning
procedures will void any warranties associated with the
compressor and cost to replace the compressor.
