18000 and CTP-NB Series Service and Installation Manual

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

7.Freight carriers can supply the necessary damage 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 and lift the unit off the skid. If the unit is on casters it can be "rolled" off the skid.

INSTALLATION

Location

Be sure the location chosen has a floor strong enough to support the total weight of the cabinet and contents. A fully loaded 72” long model may weigh as much as 2000 pounds. 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.

t is recommended that the unit be installed no closer than 1 inch from any wall.

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.

Some models have casters for your convenience, for ease of cleaning underneath and for mobility. It is important that the unit be installed in a stable condition with the front casters locked before operating.

Plumbing

Self-contained models are standard with a condensate evaporator. f, for some reason, a unit does not have a condensate evaporator, or 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 and operator’s

CAUTION 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 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 to the unit.

Self-contained units with cord and plug have an ON/OFF switch located directly behind the louvered machine compartment door.

Simply turn the switch to ON to begin operation.

The power switch must be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions. Never operate the unit without the louvered panel in place!

18000 and CTP-NB Series Service and Installation Manual

OPERATION: 18000 PTB SERIES

Product should be loaded into the unit with care. Failure to heed these recommendations could result in damage to the interior of the cabinet or the blower coil.

This unit is equipped with two on/off switches located behind the louvered machine compartment door. The unit’s compressor and all evaporator fans will begin operating when this switch is turned to the “on” position. Temperature ranges for the base are 36° to 40° F.

The switch labeled rail is for the raised rail. Turning this switch to the “on” position will activate the refrigeration for the rail. Temperature ranges for the raised rail are 33°F to 41°F.

Product located in the rail must be removed to the refrigerated base at the end of day. This allows you to turn the rail off at night to save energy and the rail will have time to defrost as needed. It also helps to maintain product quality.

A minimum of one hour of off time per day with the pans

removed from the rail is required to properly defrost the rail. If pans are left in the rail, it may take up to four hours to defrost under

the pans. Product left in the rail during a four hour off period will experience a significant rise in temperature and may not be suitable for use.

Be sure to turn the rail switch to the “on” position in the morning when you return the pans to the raised rail.

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

Never operate the unit without the louvered panel in place!

All R404A models have a high pressure limiting device. Under severe overloading conditions, or in the event of a condenser fan failure or a plugged or blocked condenser, this device may shut down the refrigeration system. This device will automatically reset, but determining the cause of the high pressure condition should be investigated by a qualified refrigeration technician.

OPERATION: 18000 BUC SERIES

After turning the ON/OFF switch to ON, the units compressor will begin operating. Delfield refrigerated bases are designed to maintain an operational temperature of 36°F to 40°F.

OPERATION: CTP-NB SERIES

The unit is equipped with one on/off switch located on the right end of the unit. The unit’s compressor will begin operating when this switch is turned to the “on” position. Temperature ranges for the rail are 33° to 41° F.

Product located in the rail must be removed at the end of day. This allows you to turn the rail off at night to save energy and the rail will have time to defrost as needed. It also helps to maintain product quality.

Product should be loaded into the unit with care. Failure to heed these recommendations could result in damage to the interior of the cabinet or the blower coil.

Overloading the storage area, restricting the air flow and continuous opening and closing of the doors and drawers will hamper the units ability to maintain operational temperature

A minimum of one hour of off time per day with the pans removed from the rail is required to properly defrost the rail. If pans are left in the rail, it may take up to four hours to defrost under the pans.

Product left in the rail during a four hour off period will experience a significant rise in temperature and may not be suitable for use.

Be sure to turn the rail switch to the “on” position in the morning when you return the pans to the raised rail.

The power switch must be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions. Never operate the unit without the louvered panel in place!

PRESSURE CONTROL SETTINGS

Pressure Control Settings

The factory recommended low-pressure control settings for 18000-PTB’s are: 55# cut-in and 30# cut-out to maintain proper temperature for product in the rail. The interior temperature is controlled by the thermostat mounted on the evaporator coil housing.

The factory recommended low-pressure control settings for 18000-BUC’s are: 82# cut-in and 57# cut-out to maintain proper temperature.

All Delfield refrigerated models come equipped with 115-volt, 60 cycle, single phase refrigeration units. The refrigeration valves are open and ready to operate as soon as the power supply cord is plugged into the standard 115volt, grounded electrical outlet.

Pressure Control

The temperature is controlled by an adjustable pressure control located in the machine compartment. An adjustable control has the word COLDER near the knob, with an arrow to indicate the adjustment direction. These controls are field adjustable and do not require a service agent. If you have any questions, feel free to contact the Delfield Service

Department.

In attempting to adjust the pressure control, you can do damage to your unit by accidentally adjusting the differential. Please make small incremental adjustments if a temperature adjustment is necessary, please contact the service department at Delfield [phone] or your local service agent. Delfield is not responsible for charges incurred while having the pressure control adjusted.
