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 and 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 by the shipping company of the
damaged equipment. This should be done within 10 days
from receipt of the equipment.
5. Be certain to check the compressor compartment housing
and visually inspect the refrigeration package. Be sure
lines are secure and base is still intact.
6. Freight carriers can supply the necessary damage forms
upon request.
7. Retain all crating material until an inspection has been
made or waived.

6000XL Series Service and Installation Manual
Serial Number Information
The serial number tag of all 6000XL Series refrigerators and
freezers is located inside the cabinet on the left side.
Always have the serial number of your unit available when
calling for parts or service. A complete list of authorized
Delfield parts depots is available at www.delfield.com.
This manual covers standard units only. If you have a custom
unit, consult the customer service department at the number
listed below.
Units represented in this manual 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
6000XL series can weigh as much as 1500 pounds. Reinforce
the floor as necessary to provide for maximum loading. For the
most efficient refrigeration, be sure to provide good air circulation
inside and out.
Inside cabinet: Do not pack refrigerator so full that air cannot
circulate. The refrigerated air is discharged at the top rear of
the unit. It is important to allow for proper air flow from the
top rear to the bottom of the unit. Obstructions to this air flow
can cause evaporator coil freeze ups and loss of temperature
or overflow of water from the evaporator drain pan. The rear
of the unit has molded ribs and the shelves have a rear turn
up on them to prevent this. However,
bags and other items can still be
located to the far rear of the cabinet.
There is also a return air diffuser
along the top front of the cabinet
interior, this also requires proper air
circulation. Prevent obstruction by
locating large boxes and tall stacks of
product to the bottom of the cabinet.
Stabilizing
Some models are supplied on casters for your convenience,
ease of cleaning underneath and for mobility. It is very
important, however, that the cabinet be installed in a stable
condition with the front wheels locked while in use.
Should it become necessary to lay the unit on its side or back
for any reason, allow at least 24 hours before start-up so as to
allow compressor oil to flow back to the sump. Failure to meet
this requirement can cause compressor failure and unit damage.
Unit repairs will not be subject to standard unit
warranties due to improper installation procedures.
Electrical connection
Refer to the amperage data on the specifications page, 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 connec tion of the line cord, or permanent connection to the unit.
The thermostat must be turned to OFF and
the unit disconnected from the power source
whenever performing service, maintenance
functions or cleaning the refrigerated area.
Outside cabinet: Be sure that the
unit has access to ample air. Avoid
hot corners and locations near stoves
and ovens.
It is recommended that the unit be installed no closer than
2” from any wall with at least 12” of clear space above the
unit. Avoid exposing glass door units to direct sunlight. Direct
sunlight through the glass doors will make the ABS liner
fade and become brittle and will greatly reduce refrigeration
efficiency.
Leveling
A level cabinet looks better and will perform better because the
doors will line up with the frames properly, the cabinet will not
be subject to undue strain and the contents of the cabinet will
not move around on the shelves. Use a level to make sure the
unit is level from front to back and side to side. Units supplied
with legs will have adjustable bullet feet to make the necessary
adjustments. If the unit is supplied with casters, no adjustments
are available. Ensure the floor where the unit is to be located
is level.
Power Switch
Select units are equipped with a power disconnect switch
located next to the energy saver switch and thermostat
control knob. Switch must be in the “on” position for the
unit to operate. On freezers, if the switch is turned off, then
returned to the on position, the unit will enter a defrost cycle
and the display will read “Def.”
Upon powering unit, there could be up to a 10
minute delay before unit begins to cool.

6000XL Series Service and Installation Manual
Electronic Temperature Control Operation
Operation:
The electronic temperature control constantly monitors box
temperature as well as evaporator coil temperature to maintain
consistent product temperatures. The control also sends
temperature readings to the digital temperature display. The
control circuits continually self-check and if an error occurs,
the digital display will switch from temperature read-out to
error read-out, i.e. E 1. Even when an error is displayed, the
refrigeration and controls system should continue to function,
however not at optimal performance. Whenever the display has
an error read-out, Delfield Service should be contacted.
At initial start-up or anytime power is disconnected, then
reconnected to the unit, the control will delay all operations for
a short time (up to 10 minutes.) While in this delay period, the
control initializes the control parameters and confirms that the
temperature sensors and circuits are operational. The digital
temperature display will not display temperature OR errors until
the self-check is complete and the control has switched on the
evaporator fan motor, compressor and condenser fan motor.
IMPORTANT NOTE REGARDING FREEZERS: After initializing,
the control will immediately 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 initialization
defrost is complete. This initial defrost cycle may take up to
15 minutes to complete, at which time the freezing cycle will
begin. The display will continue to read DEF for an additional
30 minutes before displaying temperature.
Temperature Alarm:
The alarm will flash “HI” or “LO” 90 minutes after the unit has
reached its alarm temperature point or after any power interruption
if the temperature is above or below the alarm set points.
Refrigerators are factory set at mid-range to maintain about 38ºF
(3ºC) box temperature. The high refrigerator temperature point
is 50°F (10°C). The low refrigerator temperature point is 25°F
(-4°C). Freezers are factory set at mid-range to maintain about 3ºF
(-18ºC) box temperature. The high freezer temperature point is
20°F (-7°C). Freezers do not have a low temperature point.
Refrigerator:
The control is located in the control box in the top of the
refrigerator behind the removable louvered panel on the left
side. It is factory set at mid-range to maintain about 38˚F
(3˚C) box temperature. To adjust for colder temperatures, turn
the knob clockwise. For warmer temperatures, turn the knob
counter-clockwise. Turn the knob fully counter-clockwise to
turn the refrigeration system off. Never turn the knob more
than 1 dial number and always allow 8 hours for temperature
stabilization before making any additional adjustments.
Freezer:
The control is located in the control box in the top of the
refrigerator behind the removable louvered panel on the left
side. It is factory set at mid-range to maintain about -3˚F
(-18˚C) box temperature. To adjust for colder temperatures,
turn the knob clockwise. For warmer temperatures, turn the
knob counter-clockwise. Turn the knob fully counter-clockwise
to turn the refrigeration system off. Never turn the knob more
than 1 dial number and always allow 8 hours for temperature
stabilization before making any additional adjustments.
Power Switch
Select units are equipped with a power disconnect switch
located next to the energy saver switch and thermostat control
knob. Switch must be in the “on” position for the unit to
operate. On freezers, if the switch is turned off, then returned to
the on position, the unit will enter a defrost cycle and the display
will read “Def.”
Energy Saver Switch
The energy saver switch is a rocker switch located next to
the thermostat knob that controls the amount of heat applied
to the door perimeter. The normal operating position for this
switch is the ON position, providing the least heat. If excessive
condensation is observed on the door opening, press the
energy saver switch to the OFF position, to increase the amount
of heat (red portion of the rocker switch will be visible).
Refrigeration & Defrost Cycle
Refrigerator:
Whenever the refrigerator is plugged in, and the control
has completed initializing, the digital thermostat will display
box temperature. The temperature control will cycle the
compressor, evaporator fan motor and condenser fan motor to
maintain box temperature at the control setting. See evaporator
fan matrix for more information.
Refrigerator 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).

Electronic Temperature Control Operation, continued
Freezer:
Whenever the freezer is plugged in, and the control has
completed initializing including the initial defrost cycle (also see
Electronic Temperature Control Operation, on this page). The
digital therostat will display box temperature. The temperature
control will cycle the compressor, evaporator fan motor and
condenser fan motor to maintain box temperature at the control
setting. See evaporator fan matrix for more information.
Freezer Automatic Defrost
The control also monitors compressor total running time
and will enter a defrost cycle after total compressor running
time is greater than 4-hours since the last defrost cycle OR
if evaporator coil temperature drops below -30˚F (-34°C)
(indicating excessive frost on the coil).
Freezer Manual Defrost
If a manual defrost is desired, simply unplug the unit for several
seconds, then plug unit back in. This will cause the control to
re-initialize and then enter a defrost cycle.
When the control enters the defrost mode, it switches off the
evaporator fan motor, compressor and condenser fan motor,
and switches on the defrost heater to warm the evaporator
coil. Thereby melting all frost accumulated during the previous
refrigeration cycle. The digital temperature display will now read
dEF. The control will continue the defrost cycle for a MINIMUM
of 8 minutes and a MAXIMUM of 30 minutes depending on the
amount of frost accumulated on the evaporator coil.
After the defrost cycle is complete, the control returns to a normal
refrigeration cycle, however the evaporator fan motor will not
switch on for 2 minutes AFTER the compressor and condenser
fan motor have begun operating. The digital temperature
display will continue to read dEF until the evaporator has
returned to normal freezing temperatures (up to 30 minutes).
Electronic Temperature Control Error Codes
The Danfoss control (when digital display is installed) can show
four distinct error codes. The display will continually flash
the letter error code but the control will continue running the
machine even if not most efficiently. Error codes and most likely
fix are below.
Note that the likely fix is not ALWAYS the right fix, but is the
most likely. Example: E-1 might also be caused by an open or
short in the sensor circuit within the control itself.
E-1 Box temperature sensor circuit is either open or shorted.
A. Check resistance of sensor for open or short and replace
sensor if either condition is found.
B. If sensor is not open or shorted, replace control.
E-2 Coil temperature sensor circuit is either open or shorted.
A. Check resistance of sensor for open or short and replace
sensor if either condition is found.
B. If sensor is not open or shorted, replace control.
HINT: either sensor can be removed and checked for proper
resistance. To verify resistance, submerge in ice water for
several minutes and check with ohmmeter. Correct reading
should be 16,000ohms plus or minus 1,000ohms.
E-6 Control has a defective potentiometer.
A. Replace control.
E-13 Communication error between controller and display.
A. Check for loose plug(s) on cable from control to display.
B. Replace display.
C. Replace control.
Service Alert
During normal operation the evaporator fan may cycle and/or
pulse independently of the compressor. Consult KitchenCare

CAUTION
Maintenance
Never hose down interior or exterior of units with
water. This will void the warranty. Wipe interior dry
of any water accumulation.
The thermostat 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 Delrite® ABS 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 plastic and can damage the breaker strips
and gaskets.
Cleaning the Condenser Coil
The condenser coil requires regular cleaning, recommended is
every 90 days. In some instances though you may find that
there is a large amount of debris and dust or grease accumulated
prior to the 90 day time frame. In these cases the condenser coil
should be cleaned every 30 days.
If the build up on the coil consists of only light dust and debris
the condenser coil can be cleaned with a simple brush, heavier
dust build up may require a vacuum or even compressed air to
blow through the condenser coil.
If heavy grease is present there are de-greasing agents available
for refrigeration use and specifically for the condenser coils.
The condenser coil may require a spray with the de-greasing
agent and then blown through with compressed air.
Failure to maintain a clean condenser coil can initially cause high
temperatures and excessive run times, continuous operation
with dirty or clogged condenser coils can result in compressor
failures. Neglecting the condenser coil cleaning procedures will
void any warranties associated with the compressor or 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.
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.
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 70-80%
iron which will rust. It also contains 12-30% chromium which
forms an invisible passive film over the steels 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 rust of discoloration.
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 upon completion.
Routine cleaning of stainless steel can be done with soap and
water. Extreme stains or grease should be cleaned with a nonabrasive cleaner and plastic scrub pad. It is always good to
rub with the grain of the steel. There are also stainless steel
cleaners available which can restore and preserve the finish of
the steels protective layer.
Early signs of stainless steel breakdown can consist of 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.
Gasket Maintenance
Gaskets require regular cleaning to prevent mold and mildew
build up and also to keep 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 prevent proper seals. Also, never
use sharp tools or knives to scrape or clean the gasket which
could possibly tear the gasket and rip the bellows.
Gaskets can easily be replaced and do not require the use of
tools or authorized service persons. The gaskets are “Dart”
style and can be pulled out of the grove in the door and new
gaskets can be “pressed” back into place.
10
Maintenance, continued
Doors/Hinges
Over time and with heavy use doors the hinges may become
loose. If it is noticed that the door is beginning to sag, it may
become necessary to tighten the screws that mount the hinge
brackets to the frame of the unit. If the doors are loose or
sagging this can cause the hinge to pull out of the frame which
may damage both the doors and the door hinges. In some
cases this can require qualified service agents or maintenance
personnel.
Drain Maintenance
Each unit has a drain located inside the unit which removes the
condensation from the evaporator coil and evaporates it at an
external condensate evaporator pan. Each drain can become
loose or disconnected from moving or bumping the drain. If you
notice excessive water accumulation on the inside of the unit be
sure the drain tube is connected from the evaporator housing
to the condensate evaporator drain pan. If water is collected
underneath the unit you may want to check the condensate
evaporator drain tube to be sure it is still located inside the
drain pan. The leveling of the unit is important as the units are
designed to drain properly when on a level surface, if your floor
is not level this can also cause drain problems. Be sure all drain
lines are free of obstructions, typically food product is found
blocking drain lines causing water to back up and overflow the
drain pans.
