Receiving and Inspecting the Equipment
Even though most equipment is shipped crated, care should be
taken during unloading so the equipment is not damaged while
being moved into the building.
1. Visually inspect the exterior of the package an skid or
container. Any damage should be noted and reported to
the delivering carrier immediately.
2. If damaged, open and inspect the contents with the carrier.
3. In the event that the exterior is not damaged, yet upon
opening, there is concealed damage to the equipment
notify the carrier. Notification should be made verbally as
well as in written form.
4. Request an inspection of the concealed equipment. This
should be done within 10 days from receipt of the
equipment.
5. Check the lower portion of the unit to be sure legs or
casters are not bent.
6. Also open the compressor compartment housing and

Uncrating the Equipment
First cut and remove the banding from around the crate.
Remove the front of the crate material, use of some tools will
be required. If the unit is on legs remove the top of the crate as
well and lift the unit off the skid. If the unit is on casters it can
be "rolled" off the skid.
visually inspect the refrigeration package. Be sure lines are
secure and base is still intact.
Production Centers Service and Installation Manual
Serial Number Location
The serial number on all pizza production centers is located on
the electrical specifications tag affixed inside the compressor
section next to the pressure control.
Always have the serial number of your unit available when
calling for parts or service. A complete list of authorized
Delfield parts depots can be found at www.delfield.com.
These units are intended for indoor use only. Be sure the
location chosen has a floor strong enough to support the
total weight of the cabinet and contents. A fully loaded
model may weigh as much as 1500 pounds! Reinforce the
floor as necessary to provide for maximum loading.
It is very important to allow for proper air flow, both inside
and outside.
Avoid hot corners and locations near stoves, ovens and
other pieces of cooking equipment.
It is recommended that the unit be installed no
closer than 1” from any wall. Do not install the
unit near any combustible material or object
affected by heat or moisture.
Leveling
A level cabinet looks better and will perform better because
the drain pan will drain properly, the doors will line up with
the frames properly, and the cabinet will not be subject to
undue strain.
A unit on legs will have an adjustable bullet foot on each
leg, adjust each for a level unit. A unit on casters will not
be adjustable. Be sure the unit is on a level floor, make
necessary changes to the floor for proper level.
Lock all front casters to ensure the stability of the unit.
Plumbing
Models are standard with a condensate evaporator. If, for some
reason a unit does not have a condensate evaporator, or if
the evaporator fails, the unit’s drain must have an outlet to an
appropriate drainage area or container. A refrigerated rail will

have a 1" 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.
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.
Electrical connection
Refer to the amperage data in the specification table, the serial
tag, your local code or the National Electrical Code to be sure the
unit is connected to the proper power source. A protected circuit
of the correct voltage and amperage must be run for connection
of the line cord, or permanent connection of the unit.
An ON/OFF switch is located directly behind the louvered
panel covering the compressor section. Simply turn the
switch to ON to begin operation.
The power switch must be turned to OFF and
the unit disconnected from the power source
whenever performing service or maintenance
functions.
Never operate the unit without the louvered panel
in place!
If electrical receptacles are to be mounted in the unit’s
backsplash, they must be wired independently from the
existing unit wiring.
Production Centers Service and Installation Manual
Operation
After turning the ON/OFF switch to ON the unit’s compressor
will begin operating. Delfield refrigerated bases are designed
to maintain an operational temperature of 36°F to 40°F.
Temperature in the refrigerated rail opening is 33°F to 41°F
with pans recessed 3” on a standard wrapped refrigerated rail
at 86°F ambient room temperature.
Do not place hot pans on/against the blue ABS liner.
Do not throw items into the storage area. Failure
to heed these recommendations could result in
damage to the interior of the cabinet or to the
blower coil.
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.
Refrigerated Rail
Product in the rail should be removed to the refrigerated base
at the end of the day. A rail on/off switch is provided and
is required to be shut off at night. The rail switch shuts off
the rail only. This allows you to save energy and the rail will
have time to defrost as needed. It also helps maintain product
quality. Standard wrapped refrigerated units are controlled
by the pressure control which is set to maintain the proper
rail temperature. To ensure product quality in the rail it is
recommended that product be rotated every four hours.
If adding any item to the unit, be sure to keep
in mind the location of the refrigeration lines on
wrapped rail units. A refrigeration leak in a rail
is extremely difficult and costly to repair. In some
cases it cannot be repaired at all.
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:
During the cooling mode, compressor and evaporator fan run
simultaneously.
During the compressor off mode, evaporator fan pulses three
minutes on and three minutes off.
During an actual defrost event other than the off-cycle defrost,
compressor stays off but the evaporator fan runs continuously.
Production Centers Service and Installation Manual
The base temperature control is located in the machine
compartment. It is field adjustable and does not require a
service agent. The factory setting is 2.5. Set toward 1 for
higher temperatures and toward 7 for lower temperatures.
Rail Pressure Control Settings
The rail temperature is controlled by an adjustable pressure
control located in the machine compartment. An adjustable
control has the word COLDER near the knob, with an arrow
to indicate the adjustment direction. These controls are
field adjustable and do not require a service agent. If you
have any questions, feel free to contact the Delfield Service
Department.
Please make small incremental adjustments if
a temperature adjustment is necessary. It may
take an hour or longer to realize the temperature
change depending on the application and location
of the unit.
Contact the service department at Delfield +1
(989) 773-7981 or your local service agent
for additional assistance. Delfield is not
responsible for charges incurred while adjusting
the thermostat.
The factory recommended low-pressure control settings
are: 55psi (3.79bar) cut-in and 30psi (2.07bar) cut-out to
maintain proper temperature for product in the rail.
In attempting to adjust the pressure control,
you can do damage to your unit by accidentally
adjusting the differential. Please make small
incremental adjustments if a temperature
adjustment is necessary. It may take an hour
or longer to realize the temperature change
depending on the application and location of
the unit.
Please contact the service department at Delfield
(800) 733-8829 or your local service agent.
Delfield is not responsible for charges incurred
while having the pressure control adjusted.

Maintenance
Door Gasket Maintenance
Door gaskets require regular cleaning to prevent mold and
mildew build up and also to retain the elasticity of the gasket.
Gasket cleaning can be done with the use of warm soapy water.
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 and new gaskets can be “pressed”
back into place.
Drain Maintenance - Base
Each unit has a drain located inside the unit that removes
the condensation from the evaporator coil and routes it to an
external condensate evaporator pan. Each drain can become
loose or disconnected during normal use. If you notice water
accumulation on the inside of the unit be sure the drain tube
is connected to the evaporator drain pan. If water is collecting
underneath the unit make sure the end of the drain tube is in
the condensate evaporator in the machine compartment. The
leveling of the unit is important as the units are designed to
drain properly when level. Be sure all drain lines are free of
obstructions.
Drawer Maintenance
Drawer Assembly Cleaning
The drawer assembly is designed to be cleaned easily. Both
drawer and tracks are removable without tools. The drawer
tracks are dishwasher safe or can be cleaned in a sink with
detergents and a soft bristle brush. Drawers and tracks should
be cleaned on a weekly basis.
Remove Drawers
Pull the drawer box out until it stops. Lift up on the drawer front
and pull the drawer box completely out. Using a soft bristle
brush, clean the track on the bottom of the drawer box. When
finished, it should be wiped clean of all food and debris.
Tracks
The drawer box assembly must be removed. Pull the drawer
tracks out until they hit a stop. Locate blue safety clips towards
the back of each drawer track. Blue safety clips have a tab on
the top. Push the tab back until it clicks. Lift up and pull the
drawer tracks all the way
out of the drawer cage.
The drawer tracks are

and tracks should be
any food and debris gathered on the bottom ledge. Once it’s
cleaned thoroughly with a soft bristle brush, wipe remaining
debris clean with a soft towel.
Reassembly
Push the drawer tracks into the drawer cage. The blue safety
clip must remain pushed towards the back. Lift up and slide the
drawer track all the way into the drawer cage. The blue safety
clip will lock in place automatically. Once all tracks are replaced,
insert the drawer box. Rest the drawer box bottom track on the
front track roller. Then push the drawer back in place SLOWLY.
When the drawer box is about half way in you will hit a STOP.
You must lift the front of the drawer up approximately ½”
(1.3cm) to continue inward. Clean tracks as often as possible.
The cleaner the tracks are the better they will operate.
Caster Maintenance
Wipe casters with a damp cloth monthly to prevent corrosion.
The power switch must be turned to OFF and the
unit disconnected from the power source whenever
performing service, maintenance functions or
cleaning the refrigerated area.
Refrigerators and Freezers
The interior and exterior can be cleaned using soap and warm
water. If this isn’t sufficient, try ammonia and water or a
nonabrasive liquid cleaner. When cleaning the exterior, always
rub with the “grain” of the stainless steel to avoid marring the
finish. Do not use an abrasive cleaner because it will scratch the
stainless steel and can damage the breaker strips and gaskets.
Stainless Steel Care and Cleaning
To prevent discoloration or rust on stainless steel several
important steps need to be taken. First, we need to understand
the properties of stainless steel. Stainless steel contains 7080% iron, which will rust. It also contains 12-30% chromium,
which forms an invisible passive film over the steel’s surface,
which acts as a shield against corrosion. As long as the
protective layer is intact, the metal is still stainless. If the film
is broken or contaminated, outside elements can begin to
breakdown the steel and begin to form discoloration or rust.
Proper cleaning of stainless steel requires soft cloths or plastic
scouring pads.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
Cleaning solutions need to be alkaline based or non-chloride
cleaners. Any cleaner containing chlorides will damage
the protective film of the stainless steel. Chlorides are also
commonly found in hard water, salts, and household and
industrial cleaners. If cleaners containing chlorides are used be
sure to rinse repeatedly and dry thoroughly. Routine cleaning
of stainless steel can be done with soap and water. Extreme
Production Centers Service and Installation Manual
stains or grease should be cleaned with a non-abrasive cleaner
and plastic scrub pad. Always rub with the grain of the steel.
There are stainless steel cleaners available which can restore
and preserve the finish of the steels protective layer. 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 passivity of the steel.
Never use an acid based cleaning solution! Many
food products have an acidic content, which can
deteriorate the finish. Be sure to clean the stainless
steel surfaces of ALL food products. Common items
include, tomatoes, peppers and other vegetables.
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 at least every
three months. If conditions are such that the condenser is totally
blocked in three months, 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.
Never use a high-pressure water wash for this
cleaning procedure as water can damage the
electrical components located near or at the
condenser coil.
Doors/Hinges
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.
maintain operational temperature.
Refrigerated rail units
Product in the rail should be removed to the refrigerated base
at the end of the day. An on/off switch is provided for the rail
and is required to be shut off at night. This allows you to turn
the rail off at night to save energy and to defrost the rail. It
also helps maintain product quality. The standard wrapped
refrigerated rail units are controlled by a low-pressure control
that is set to maintain the proper rail temperature. To ensure
product quality in the rail it is recommended that product be
rotated every four hours.
If adding any item to the unit, be sure to keep in mind
the location of the refrigeration lines on wrapped
rail units. A refrigeration leak in a rail is extremely
difficult and costly to repair. In some cases it cannot
be repaired at all.
Preventing blower coil corrosion
To help prevent corrosion of the blower coil, store all acidic
items, such as pickles and tomatoes, in sealable containers.
Immediately wipe up all spills.
Units with pans should be operated with pans in
place. Operating the unit without all pans in place
will lower efficiency and may damage the unit.
Continuous opening and closing of the doors will hamper the
unit’s ability to maintain optimum refrigeration temperature.
Top section is not intended for overnight storage. Product
should be removed from pans. Pans can remain in unit while
empty.
Never use sharp objects or tools to clean or scrape ice/frost
build up from the refrigerated cold pans. A puncture to the pan
could cause irreparable damage to the refrigeration system.
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.
Do not place hot pans on/against the blue ABS liner.
Do not throw items into the storage area. Failure
to follow these recommendations could result in
damage to the interior of the cabinet or to the blower
coil. Overloading the storage area, restricting the
airflow, and continuous opening and closing of the
doors and drawers will hamper the units ability to
