Although most Delfield equipment is shipped crated, care
should be taken so the equipment is not damaged during
unloading and movement into the building.
Upon receipt of the shipment, be sure all items are included
and are undamaged. If there is damage, see the section on
“filing Freight Claims” for information on claims procedures.
All Delfield Custom Systems line-ups have been assembled
at the factory before shipment. Each unit is marked with the
work order number, item number and serial number. The
unit item number is identical to that marked on the sales
presentation drawing. Use these numbers as a guide during
installation.
Bolts, screws and other accessories needed for fastening
units together are in an envelope located inside one of the
units. The unit is marked with a note attached to the front.

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 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. Check the lower portion of the unit to be sure legs or
casters are not bent.

6. Also open the compressor compartment housing and
visually inspect the refrigeration package. Be sure lines
are secure and base is still intact.

7. Freight carriers can supply the necessary damage forms
upon request.

8. Retain all crating material until an inspection has been
made or waived.

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.

Tools And Supplies Required

A steel hammer and a block of wood can be used to make

Units represented in this manual are for indoor use only.

The following tools are either required or will
make the installation easier:

A scissor jack to lift and hold heavy units off the floor so

1)
that legs can be adjusted, allowing the proper leveling of
the units.
A level is needed to assist in the leveling of each unit

2)
from front to back and left to right. A 2’ (61cm) level is a
must; a 4’ (122cm) level is also desirable.
Two 6’ (183cm) pipe clamps are useful in pulling

3)
equipment tightly together while fasteners are installed.
This results in a better spline.
Vise grips will hold backsplash bars together as they are

4)
being bolted together.

Maintenance

5)
minor alterations of the stainless steel along the seam
between two units, in order to perfect the seam. This is
used after the units are splined.
A rubber mallet.

6)
A socket set.

7)
Phillips, hex head and straight blade screwdrivers.

8)
7/16” (1.1cm), 9/16” (1.4cm) and 1/2” (1.3cm) open end

9)
wrenches.
Silicone sealant; Dow Corning #732 is ideal.

Stainless Steel Care and Cleaning

To prevent discoloration of 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.

The power must be turned off and disconnected
whenever performing maintenance or repair
functions.

The interior of heated storage cabinets will be hot
for some time after the power is turned off. Avoid

touching the interior walls and heater ducts with
bare hands or arms until you are certain the unit
has cooled. The use of gloves is recommended.

Do not use a water jet, hose or pressure washer
on these units. The water will damage the
components.

Maintenance, continued

Component Crafted Custom Equipment - Line Ups Service and Installation Manual

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.

Drain Maintenance

Each refrigerated 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.

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.

Doors/Hinges

Over time and with heavy use doors and 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.
