The serial number on self-contained refrigerated units is on the electrical specifications tag located near the condensing unit. The serial number tag also lists the refrigerant used and the amount of charge.

Always have the serial number of your unit available when calling for parts or service. A complete list of authorized Delfield parts depots is shown on the back cover of this manual.

This manual covers only standard 8100-EF series units. If you have a custom designed unit, you should contact our service department for parts and service questions.

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.

Carefully check for any visible signs of damage to the cartons or containers. If evidence of damage exists, the package should be opened immediately and a joint inventory and examination of the contents should be made by you and the driver. Sign delivery receipt as damaged. Example - if (2) pieces of (5) are damaged, you must indicated the number of units damaged.

Concealed damage

If a concealed loss or damage is discovered after you have given the carrier a clear delivery receipt, notify the carrier in

writing immediately or within 10 days from the delivery date. If you phone the carrier, you must follow up the call in writing to protect your rights. You can only improve your position as a claimant by promptly reporting such loss or damage. You should also retain all cartons or containers, including packing material, until an inspection has been made or waived.

Filing a claim

Notation of loss or damage does not constitute the filing of a claim. You should file your claim in writing with the carrier immediately.

Carriers will furnish the necessary form upon request. You should also request an inspection. If a claim is filed by phone, always follow up immediately in writing.

8100-EF Series Service and Installation Manual

Installation

Drop In Procedure

These units are designed to be used only in air conditioned areas. A room temperature of not more than 75ºF (24ºC) is recommended. Reinforce the counter as necessary to provide for maximum loading.

Do not install the unit within three inches of any combustible material or object affected by heat

DANGER or moisture.

The counter cut-out sizes and power requirements are shown on page 2. For units manufactured after August 1, 2001, the gasket will be pre-installed at the factory. For units manufactured before August 1, 2001, after the cut-out is made, lay the gasket on the counter around the cut-out opening. Place the unit over the gasket. The weight of the unit on the gasket forms a seal preventing liquids from seeping into the cut-out opening.

Louvers

Self contained refrigerated units (8100-EF Series) require airflow to the compressor. A 13” x 25” louver is (33cm x 63.5cm) provided by Delfield and must be installed in the counter in front of the condenser. See specifications on page 2 for louver cutout dimensions. The rear must have an opening to permit removal of heated air. The opening must be at least 8” x 11”, a total of 88 square inches (20.3cm x 27.9cm, a total of 566 square centimeters).

Plumbing

The unit’s 1.00” diameter 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 and
CAUTION	operator’s responsibility to provide a container
	or outlet for drainage.

Electrical Connection

Refer to the amperage data on page 2, the serial tag, your local code and the National Electrical Code to be sure the 8100-EF Series 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.

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

Never operate the unit without the louvered panel in place.

Operation

8100-EF Series cold pans are adjusted at the factory to provide satisfactory operation without any further adjustments. However, if it is necessary to adjust the temperature, the control is located in the machine compartment. Turn the knob clockwise as indicated on the control. Settings are from 1 through 7; 7 being the coldest. Adjustments should be made gradually. Several small adjustments will be more effective than one large adjustment. It may take an hour or longer to realize the temperature change depending on the application and location of the unit.

These units are not designed to cool warm food products. Items should be placed in the unit pre-cooled at least to the desired holding temperature, if not slightly colder. In some applications, a gradual warming of product may occur, particularly at the exposed top of the product. Stirring or rotation of the product may be necessary to maintain overall temperature. Warming of food product can occur very quickly outside of the unit. When loading or rotating the product, avoid leaving food items in a non-refrigerated location for any length of time to prevent warming or spoilage.

The temperature control is used to turn the unit on and off as well as control the temperature of the cold pan. The settings range from 1 through 7 (7 being the coldest). To turn the cold pan off, turn the knob to the off position.

The cold pan is not intended to be used with ice.
