EXPANSION VALVE ADJUSTMENT

Expansion valves must be adjusted to fully feed the evapo- rator. 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 operat- ing 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.

3. The difference is superheat.

5. Set the superheat for 5° F - 7° F.

NOTE: Slow air picks up more humidity from coil and ice.

ELECTRICAL CIRCUIT IDENTIFICATION

Standard lighting for all models will be full length fluores- cent 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 merchan- diser are intended for scales and lighted displays.They are not intended nor suitable for large motors or other external appliances.

BEFORE SERVICING

ALWAYS DISCONNECT ELECTRICAL POWER AT THE MAIN DISCONNECT WHEN SERVICING OR REPLACING ANY ELECTRICAL COMPONENT.

This includes (but not limited to) Fans, Heat-

ers, Thermostats, and Lights.
