Refrigeration (Cont'd)

Electronic Expansion Valve (Optional)

A wide variety of electronic expansion valves and case controllers can be utilized. Please refer to EEV and controller manufacturers information sheet. Sensors for electronic expansion valves will be installed on the coil inlet, coil outlet, and in the discharge air. (Some supermarkets require a 4th sensor in the return air). Case controllers will be located in the electrical raceway or under the case. The front Self Service Evaporator has an EPR valve installed to maintain a constant discharge temperature. It is located in the front at the right side of the case under the fan plenum near the TX valve.

Thermostatic Expansion Valve Location

This device is located on the same side as the refrigeration stub. A Sporlan balanced port expansion valve model is furnished as standard equipment, unless otherwise specified by customer.

Expansion Valve Adjustment

Expansion valves must be adjusted to fully feed the evaporator. Before attempting any adjustments, make sure the evaporator is either clear or very lightly covered with frost, and that the fixture is within 10°F of its expected operating temperature.

Measuring the Operating Superheat

1.Determine the suction pressure with an accurate pressure gauge at the evaporator outlet.

2.From a refrigerant pressure temperature chart, determine the saturation temperature at the observed suction pressure.

3.Measure the temperature of the suction gas at the thermostatic remote bulb location.

4.Subtract the saturation temperature obtained in step No. 2 from the temperature measured in step No. 3. The difference is superheat.

5.Set the superheat for 5°F - 7°F.

Evaporator Pressure Regulator

An Evaporator Pressure Regulator is installed in the front of the self service section to maintain a constant discharge temperature. It is located at the front right side of the case, under the fan plenum near the TX Valve.

Service Case Temperature Control

Temperature control in the upper section of the R3 with the Service Option is done by means of a thermostat and suction solenoid valve. This controls both temperature and humidity.

T-STAT Location

T-STATS are located within the electrical raceway. Refer to diagram below.

CASE MUST BE GROUNDED

NOTE: Refer to label affixed to case to determine the actual configuration as checked in the “TYPE INSTALLED” boxes.

Electrical Circuit Identification

Standard lighting for all refrigerated models will be full length fluorescent lamps located within the case at the top.

The switch controlling the lights, the plug provided for digital scale, and the thermometer are located at the rear of the case mullion.

The receptacle that is provided on the exterior back of these models is intended for computerized scales with a five amp maximum load, not for large motors or other high wattage appliances. It should be wired to a dedicated circuit.

Electrical Service Receptacles (When Applicable) The receptacles located on the exterior of the merchandiser are intended for scales and lighted displays. They are not intended nor suitable for large motors or other external appliances.
