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.

Serial Number Location

The serial number is located on the rear of the unit on the bottom right hand side.

Always have the serial number available when calling for parts or service.

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

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

7. 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.

Warning: While uncrating do not lay unit on side. If compressor is set on side, return to upright position for 24 hours to allow for all compressor oil to drain back into compressor.

Installation

Dual View Series Service and Installation Manual

Location

These units are intended for indoor use only. Be sure the location chosen has a floor strong enough to support 1000 pounds of the cabinet and contents. Reinforce the floor as necessary to provide for maximum loading.

For the most efficient refrigeration, be sure to provide good air circulation inside and out.

Inside cabinet: Do not pack refrigerator so full that air cannot circulate.

Outside cabinet: Be sure that the unit has access to ample air. Avoid hot corners and locations near stoves and ovens.

Leveling

A level cabinet looks better and will perform better because:

1. The drain pan will drain properly.

2. The doors will line up with the frames properly.

3. The cabinet will not be subject to undue strain.

To meet NSF standards, this unit must be sealed to the floor.

Installation of glass shelves

1. Remove stainless steel shelf bracket assemblies by sliding key slots over shoulder bolts on inside edges of posts.

2. Plug light cords into receptacles.

3. Place 0.25” safety glass shelves on brackets.

Installation of dry section front & side glass

1. Remove (2) acorn nuts on bottom side of shelf.

2. Remove top of stainless steel shelf by lifting shelf off subtop.

3. Place 0.25” thick side glass pieces into bottom channel and lower rear of stainless steel shelf.

4. Place 0.25” thick front glass piece into bottom channel and lower front of stainless steel shelf over top edge of glass.

5. Replace acorn nuts on bottom side of shelf.

Plumbing

Self-contained models are standard with a 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 wattage data on page 2, the serial tag and your local code to be sure the unit is connected to the proper power source. A protected circuit of the correct voltage and amperage must run for connection of the line cord, or permanent connection to the unit.

Self-contained units have an ON/OFF switch located in the base of the unit. Simply turn the switch to ON to begin operation.

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

Operation Information

On self-contained models, after turning the ON/OFF switch to ON, the unit’s compressor will begin operating. Delfield display cases are designed to maintain an operation temperature of 36°F to 40°F at ambient room temperature of 75°F and relative humidity of 55%.

Do not load the storage area in a way that restricts the air flow. Overloading will result in a loss of temperature.

Continuous opening and closing of the doors will hamper the units ability to maintain operational temperature.

Display Case Glass Replacement

Delfield professionally packages the glass in the crate to minimize the risk of freight damage. However, during shipment glass damage can happen and breakage is not covered under warranty. If your Delfield unit arrives with broken glass in the top dry section, we recommend that you purchase replacement glass locally. The table to the right lists replacement sizes for the dry top section only.

Please call your Delfield service or sales representative if you have any questions on glass replacement.

Maintenance

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.

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 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.

Doors/Hinges

Over time and with heavy use doors the hinges may become loose. If this happens tighten the screws that mount the hinge brackets to the frame of the unit. Loose or sagging doors can cause the hinges to pull out of the frame, which may damage both the doors and the hinges. In some cases this may require qualiﬁed service agents or maintenance personnel to perform repairs.

Do not place hot pans on/against the blue ABS liner. Do not throw items into the storage area. Failure to follow these recommendations could result in damage to the interior of the cabinet or to the blower coil. Overloading the storage area, restricting the airﬂow, and continuous opening and closing of the doors and drawers will hamper the units ability to maintain operational temperature.

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.

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. There are stainless steel cleaners available which can restore and preserve the ﬁnish of the steels protective layer. 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.

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.

Units with pans should be operated with pans in place. Operating the unit without all pans in place will lower efﬁciency and may damage the unit.

Continuous opening and closing of the doors will hamper the unit’s ability to maintain optimum refrigeration temperature. Top section is not intended for overnight storage. Product should be removed from pans. Pans can remain in unit while empty.

Cleaning the condensate evaporator (remote models only)

The stainless steel condensate evaporator pan should be cleaned every six months. Use a vacuum cleaner or damp cloth to remove dust that may have accumulated. This will prevent corrosion of the stainless steel.
