Installation

Location

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 on pages 3, 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.

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 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.

Pressure Control Settings

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.
The interior temperature is controlled by the thermostat
mounted on the evaporator coil housing.

Pressure Control

The 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.

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, please contact the
service department at Delfield [phone]
or your local service agent. Delfield is not
responsible for charges incurred while having
the pressure control adjusted.

Maintenance

EXCELeration™ Series Service and Installation Manual

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

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 70- 80%
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
stains or grease should be cleaned with a non-abrasive cleaner
and plastic scrub pad. Always rub with the grain of the steel.
