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.
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

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.
Unit is designed to maintain 36°F - 40°F (2°C - 4°C) at 80°F
(27°C) ambient room temperature in 55% or lower relative
humidity.
Units represented in this manual are for indoor use only. Be sure
the location chosen has a counter strong enough to support the
total weight of the cabinet and contents. A fully loaded model
may weigh as much as 1,500 pounds! Reinforce the counter as
necessary to provide for maximum loading.
These units are installed by placing them into the counter from
above. The counter cutout sizes are as follows:
36" Units - 35.13" x 25.50" (89cm x 65cm)
48" Units - 47.13" x 25.50" (120cm x 65cm)

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.
Failure to provide the proper air flow will void the warranty.
Plumbing
Standard models will have a 1/2" drain which will need to be run
to an appropriate floor drain. The drain will be stubbed inside
the machine compartment. All units have an optional electric
condensate evaporator. If the evaporator fails, the unit’s drain
must have an outlet to an appropriate drainage area or container.
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 page 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 con nec tion of the
line cord, or permanent connection to the unit.
An ON/OFF switch is located on the remote control panel. Simply
turn the switch to ON to begin operation. There is a second ON/
OFF switch on the remote control panel for the lights.
The power switch should be turned to OFF and
the unit disconnected from the power source
whenever performing service or maintenance
functions.
1. Remove the stainless steel pans in the bottom on the
unit.
2. Remove the stainless steel pan clip rail below the door
track.
3. Bolt in the lifting plates using the bolts (P/N 9320019)
located inside the tank that are installed in the lifting
braces.
4. Slide two 1"steel pipes into the lifting plate holes. Place
forklift forks under the pipes and clamp the forks and
pipes in position.
5. Raise the unit high enough with the forklift to roll the
base under the unit into position. Lower the ASM unit into
the base using care to clear all of the flanges and screw
heads.
6. Remove the bolts and remove the lifting plates. Install
plastic plugs (P/NRTPOOO67) in the bolt holes.
7. Install the stainless steel pan clip rail below the door
track.
8. Install the stainless steel pans in the bottom on the unit
making sure the turn down is engaged in the slot below
the door track.
9. Install the sneeze guard glass in the clips and attach the
end clip with two stainless steel self tapping screws (P/
N9321238).
10. Use gray silicone (P/N9291020) to finish the joint
between the drop in unit and the top of the base.
Located on the Remote Control Panel are two ON/OFF
switches. One will turn ON/OFF the unit’s com pressor. The
lights are controlled by the other switch.
Delfield's Air Screen Merchandisers are designed to maintain
an operational temperature of 36°F - 40°F (2°C - 4°C) at 80°F
(27°C) ambient room temperature in 55% or lower relative
humidity. Overloading the merchandiser, restricting the air
flow, and continuous opening and closing of the doors will
hinder the unit’s ability to maintain operational tem per a tures.
If humidity is above 55%, condensation on the glass
will be present.
Sliding Door Removal And Reinstall
Sliding Door Removal
Open the door almost completely. Firmly grasp both sides of
the door. Lift the door up and move it until it enters a notch
and can be lifted higher. Tilt the bottom out without removing
the top. Use the top to gently return the spring to the closed
position. Remove the door from the top track.
Proper airflow is critical to maintaining temperature. Do not
interfere with the airflow by placing product over the air return
openings. The Air Diffuser Pan Assembly must be properly
in place at the bottom of the merchandising case, with the
air return openings on the customer side. After cleaning or
servicing the Front Deflector Glass, Honeycomb Diffuser and
Airduct Plexiglas Panel must be replaced properly.
Sliding Door Reinstall
There is a notch in the top inside corner of the door. Put the
spring in the door's notch and move the spring to the open
position. Put the top into the track and find the notch where the
door can be lifted higher. Set bottom of the door into the track.
Night & Security Cover Operations
At the factory, the keys are taped to the display case. Pull the
cover down, turn the key 90° to lock.
Each unit has a drain located inside the unit that removes the
condensation from the evaporator coil. The drain can become
loose or disconnected during normal use. If you notice water
accumulation be sure the drain tube is connected. Be sure drain
lines are free of obstructions.
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.
Plexiglas, Including Baffles
Wet a clean cloth with lukewarm water and dishwashing liquid.
Apply only light pressure, rinse with clean water and blot dry with
a damp chamois. For excessively dirty surfaces, rinse surface
dirt off before washing. Fine scratches will disappear when you
polish by hand with a plastic cleaner polish.
Never use window sprays, kitchen scouring compounds
or solvents such as acetone, gasoline, benzene,
alcohol, carbon tetrachloride or lacquer thinner to
clean plexiglas.
Stainless Steel Care and Cleaning
To prevent discoloration or rust on stainless steel, 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 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.
Display Case
Do not throw items into the merchandiser. Failure to
follow this recommendation could result in damage
to the interior or blower coil. Overloading, restricting
the airflow, and continuous opening and closing of
the doors will hamper the units ability to maintain
operational temperature.
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.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
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. 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.
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. 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.
Frequent, regular cleaning with a mild soap and water solution
will keep the tracks free of foreign matter and will insure many
years of service. The glass may be cleaned with one of the many
commercial glass cleaners currently available.
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.
