Installation

F18 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 the total weight of the cabinet and contents. A fully loaded 72” (183cm) long model may weigh as much as 1500 pounds (680kg)! Reinforce the floor as necessary to provide for maximum loading.

It is very important to allow for proper air flow, both inside and outside.

Avoid hot corners and locations near stoves, ovens and other pieces of cooking equipment.

It is recommended that the unit be installed no closer than 1” (2.54cm) from any wall. Do not install the unit near any combustible material or object affected by heat or moisture.

PDL models also require 14" (36cm) clearance at the top and 6" (15cm) clearance at the bottom (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

Self-contained 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. A refrigerated rail will have a 1" (2.54cm) drain which will need to be run to an appropriate floor drain or container. The drain will be stubbed to the bottom of the machine compartment. Either run drain to a floor drain or add a valve to the base of the machine compartment and drain the rail to a container when convenient. The LiquiTec option will NOT have a drain available.

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 specification pages amperage data, 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.

Self-contained units with a cord and plug have an ON/OFF switch located directly behind the louvered panel covering the compressor section. 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!

If electrical receptacles are to be mounted in the unit’s backsplash, they must be wired independently from the existing unit wiring.

F18 Series Service and Installation Manual

Refrigerator Operation

Power up the unit by turning ON the unit’s ON/OFF switch. Delfield refrigerated bases are designed to maintain an operational temperature of 36°F to 40°F (2°C to 4°C). Temperature in the salad top and refrigerated rail opening is 33°F to 41°F (0°C to 5°C) with pans recessed 2” (5.1cm) on a standard wrapped refrigerated rail or flush with the LiquiTec option at 86°F (30°C) ambient room temperature.

Do not place hot pans on/against the blue ABS liner. Do not throw items into the storage area. Failure to heed these recommendations could result in damage to the interior of the cabinet or to 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.

Refrigerated rail units

Product in the rail should be removed to the refrigerated base at the end of the 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 maintain product quality. The standard wrapped refrigerated units are controlled by the pressure control which is set to maintain the proper rail temperature. An on/off switch is also provided for the rail and is required to be shut off at night. The rail switch shuts off the rail only. With a LiquiTec rail a thermostat is provided to maintain rail temperature as well as the rail on/off switch. The LiquiTec rail is required to be shut off at night as well to allow for defrosting. To ensure product

quality in the rail it is recommended that product be rotated every four hours.

If adding any item to the unit, be sure to keep in mind the location of the refrigeration lines on wrapped rail units. A refrigeration leak in a rail is extremely difficult and costly to repair. In some cases it cannot be repaired at all.

Refrigerator Evaporator Fan Operation

When the refrigerator is initially powered up or immediately following a power outage the unit will begin cooling after a 3-6 minute delay. During normal operation the evaporator fan pulses independently of the compressor as dictated by the controller as follows:

1. During the cooling mode, compressor and evaporator fan run simultaneously.

2. During the compressor off mode, evaporator fan pulses three minutes on and three minutes off.

3. During an actual defrost event other than the off-cycle defrost, compressor stays off but the evaporator fan runs continuously.

Freezer Operation

Power up the unit by turning ON the unit’s ON/OFF switch. Delfield freezer bases are designed to maintain an operational temperature of 0°F (-18°C).

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.

Freezer Evaporator Fan Operation

The evaporator fan(s) and condenser fan will cycle off and on with the compressor to conserve energy. The temperature control will cycle the compressor and condenser fan motor and evaporator fan motor to maintain box temperature at the control setting.

Temperature Control Settings

F18 Series Service and Installation Manual

A thermostat controls temperature in the self-contained F18WC, F18FC, F18MC base, F18SC base, F18RC base, F18DC base, F18PD base and F18PD rails.

Thermostats are located in the machine compartment. They are field adjustable and do not require a service agent. The factory setting is 2.5. Set toward 1 for higher temperatures and toward 7 for lower temperatures.

A thermostat controls temperature in the remote F18FR. The temperature control is located in the machine compartment. It is field adjustable and does not require a service agent. The factory setting for a remote freezer is 0°F cut-in with a 5°F differential.

Pressure Control Settings

A pressure control controls temperature in the F18MC mega top, F18SC salad top, F18RC rail and F18DC rail.

The factory recommended low-pressure control settings are: 55psi cut-in and 30psi cut-out to maintain proper

temperature for product. The interior temperature is controlled by the thermostat mounted in the mechanical compartment.

A pressure control is located in the machine compartment. An adjustable control has the word COLDER on the knob, with an arrow to indicate the adjustment direction. These controls are field adjustable and do not require a service agent.

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 (800) 733-8829 or your local service agent. Delfield is not responsible for charges incurred while having the pressure control adjusted.

Please make small incremental adjustments if a temperature adjustment is necessary. Contact the service department at Delfield +1 (989) 7737981 or your local service agent for additional assistance. Delfield is not responsible for charges incurred while adjusting the thermostat.
