6000XL Series Service and Installation Manual

Delfield

Installation

Location

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.

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.

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 con nec 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.

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.

Operation

Electronic Temperature Control
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.

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.”

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.

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).

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

6000XL Series Service and Installation Manual

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).

Service Alert
During normal operation the evaporator fan may cycle
and/or pulse independently of the compressor. Consult
the service manual or contact Technical Support at
1-800-733-8829 if you are unsure of the proper function.
