leak in a rail may be irreparable or extremely difficult and
costly to repair.

Location

Warning

n

This equipment must be positioned so that the plug is
accessible unless other means for disconnection from the
power supply (e.g., circuit breaker or disconnect switch)
is provided.

Warning

n

Adequate means must be provided to limit the movement
of this appliance without depending on or transmitting
stress to the electrical conduit or gas lines.

The location selected for the equipment must meet the
following criteria. If any of these criteria are not met, select
another location.

Electrical Service

DANGER

Check all wiring connections, including factory terminals,
before operation. Connections can become loose during
shipment and installation.

Warning

n

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.

• Plug units with R290 refrigerant into a receptacle that is a
minimum of 14” (36cm) above the floor.

• All electrical work, including wire routing and grounding,
must conform to local, state and national electrical codes.

• The equipment must be grounded.

• A separate fuse/circuit breaker must be provided for each
unit.

• The maximum allowable voltage variation is ±10% of the
rated voltage at equipment start-up (when the electrical
load is highest).

• If optional electrical receptacles are mounted in the unit’s
backsplash, they must be wired independently from the
existing unit wiring.

• 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

Self-contained work tables come standard with a condensate
evaporator. If the condensate evaporator fails, the unit’s
drain must have an outlet to an appropriate drainage area or
container.

A refrigerated rail will have a 1” (25mm) drain which will
need to be run to an appropriate floor drain or container.
The drain will be stubbed to the bottom of the machine
compartment. Either run drain to a floor drain or add a valve
to the base of the machine compartment and drain the rail
to a container when convenient.

Warning

n

Moisture collecting from improper drainage can create a
slippery 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.

Warning

n

The unit must be installed in a stable condition with
the front wheels locked. Locking the front casters after
installation is the owner’s and operator’s responsibility.

Leveling

After the cabinet has been placed in the desired location,
cabinets with legs must be leveled. Level units from front to
back and from 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 properly 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: 9291455 08/17 15

Operation Section 3

CTP-NB Series, Countertop Prep Rail

115V & 230-240V

The unit is equipped with one On/Off switch located on
the right end of the unit. The unit’s compressor will begin
operating when this switch is turned to the On position.
Temperature ranges for the rail are 33°F to 41°F (1°C to 5°C).

A minimum of one hour of off time per day with the pans
removed from the rail is required to properly defrost the rail.

Refrigerated Work Tables

Delfield refrigerated bases are designed to maintain an
operational temperature of 36°F to 40°F (2°C to 4°C). Self­contained 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.

REFRIGERATED RAILS

Temperature in the refrigerated rail is designed to maintain
33°F to 41°F (0°C to 5°C). An ON/OFF switch is also provided
for the rail; it shuts off the rail only.

Product in the rail should be moved to the refrigerated base
at the end of the day. This allows you to turn the rail off at
night to save energy and time to defrost as needed. It also
helps maintain product quality. A minimum of one hour of off
time per day with the pans removed from the rail is required
to properly defrost the rail.

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.

Work Table 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.

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 Work Table Evaporator Fan
Operation on page 16.

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.

Maintenance Section 4

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.

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.
