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 of the concealed 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

7. Freight carriers can supply the necessary forms upon

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

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.

Glass Door Merchandiser Installation, Use And Care Manual

CAUTION

Installation

Location

The cabinet is 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 1,000 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. Allow space for air circulation in the refrigeration
condensing unit compartment.

Avoid hot corners and locations near stoves, ovens and
other pieces of cooking equipment. Ambient temperature
must be between 59°F (15°C) and 86°F (30°C). Low ambient
temperatures below 50°F (10°C) are as harmful as high
ambient temperatures.

Cabinets should never be placed in front of windows or glass
doors where sunlight will be in direct contact with the units.
If a cabinet is located near a window or glass door, provide an
adequate shade to block the sun's rays.

It is recommended that the unit be installed
no closer than 1” from side walls and 8" from
the back wall. Do not install the unit near any
combustible material or object affected by heat
or moisture.

Leg and Caster Installation

Some cabinets may weigh 1000 lbs (450 kg). Use
a lifting device capable of supporting the unit

when removing skid or installing legs or casters.

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.

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 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 connection of the line cord, or permanent connection
of the unit.

To install the legs, or casters:

1. Remove unit from skid.

2. Raise unit to access leg/caster mounting holes on bottom
of unit.

3. Attach the casters or legs with the four hex head bolts.

6

For customer service, call [phone], [phone], Fax [phone], www.deleld.com

The unit must be disconnected from the
power source whenever performing service or
maintenance functions.

Never operate the unit without the louvered
panel in place!

Operation

Glass Door Merchandiser Installation, Use And Care Manual

After the unit is plugged in, the unit’s compressor will begin
operating. If the condensing unit does not run check to see
that the temperature control is not in the “OFF” position.
Before loading the cabinet, allow the cabinet to operate for at
least two hours to ensure the cabinet has achieved the desired
temperature.

Do not throw items into the storage area. Failure to
heed this recommendation could result in damage
to the interior of the cabinet or to the blower coil.

Overloading the storage area, blocking the cold
air as it exits the evaporator, and continuous
opening and closing of the doors and drawers will
hamper the units ability to maintain operational
temperature.

Continuous opening and closing of the door will hamper the
cabinet’s ability to maintain optimum refrigeration temperature.

Defrosting

Refrigerators defrost automatically with every cycle of the
compressor. The water generated is routed to a pan on the rear
of the cabinet and is evaporated by the heat given off by the
compressor.

Temperature Control Settings

DMER7-G, DMER12-G, DMER17-G, DMER26-G, DMER33-SLG, DMER45-SLG, DMER49-G, DMER65-G, DMER67-SLG

The refrigeration temperature controls are factory-set to maintain
a temperature range or 35°F to 41°F (2°C to 5°C), with an
average temperature of 38°F (3°C). For a different cabinet
temperature setting, turn the temperature control knob or screw,
located on the evaporator coil/blower housing.

Turn the control knob clockwise to lower the temperature
and counterclockwise to raise it. Adjust the control knob in
increments of 1/4 turn and allow the unit to operate for several
hours before making any further adjustment. Once it is set there
should be no need to change it.

Setting the temperature control to the coldest
setting may cause the coil and/or air ducts to
freeze and ice up. This will eventually result in a
warmer cabinet temperature.

If ice accumulation occurs and the temperature is
lower than the guidelines, turn the control knob to
a warmer setting.

Temperature Control Settings For Model DMER3-G

The DMER3-G model electronic thermostat that is located
at the upper right corner, above the sign of the unit. The
thermostat has a digital thermometer that constantly
shows the temperature of the refrigerator.

The electronic thermostat controls the temperature in
ranges from 32°F to 44°F (0°C to 7°C). This electronic
thermostat allows you to select three temperature ranges
by means of a switch located in the upper front part of the
interior refrigerator cabinet.

Select position 1or - to set the range:
37°F to 44°F (3°C to 7°C)
Select position 2 or O to set the range:
35°F to 43°F (2°C to 6°C)
Select position 3 or = to set the range:
32°F to 39°F (0°C to 4°C)
