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

visually inspect the refrigeration package. Be sure lines are secure and base is still intact.

7.Freight carriers can supply the necessary 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.

Glass Door Merchandiser Installation, Use And Care Manual

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.

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.

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

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

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

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.
