Evaporator Superheat Check

Suction Pressure Measurement

Select the method to measure suction pressure

Enter the suction pressure at the bulb location

Measure the temperature of the suction line at the thermostatic expansion valve bulb location

Convert the suction pressure to saturated evaporator temperature using a Pressure-Temperature chart

Calculate the actual superheat at the evaporator by subtracting the saturated temperature from the actual suction line temperature

Superheat Evaluation

Is the superheat within the range of 6 to 10 °F (3.4 to 5.6 °C) for systems with a 10 °F (5.6 °C) design TD?

Is the superheat within the range of 12 to 15 °F (6.7 to 8.4 °C) for systems with a higher operating TD?

Run this procedure

2 Weekly Condensing Unit System Check

Compressor Pressure Check

Enter the compressor discharge pressure

Enter the compressor suction pressure

Are the pressures within allowable design limits?

Refrigerant System Check

Check the liquid line sight glass and expansion valve operation

Is there an indication of low refrigerant?

Compressor Oil Level Check

Enter the oil level in the compressor sight glass

Run this procedure

Compressor Superheat Check

Compressor Suction Superheat Measurement

Measure the suction pressure at the suction service valve of the compressor

Measure the suction temperature of the suction line about 6 inches (15 cm) back from the compressor suction valve using an accurate thermometer.

Calculate the actual superheat at the compressor

Superheat Evaluation

Is the suction superheat within the range of 20 to 45 °F (11.2 to 25.2 °C)?

Adjustment of Suction Superheat

Is adjustment to the suction superheat required?

Methods to adjust suction superheat

Run this procedure

6 Monthly Condensing Unit Check

Pre-Inspection Safety

Disconnect and lock off the main power supply

Electrical System Inspection

Check electrical components and tighten any loose connections

Check all wiring and electrical insulators

Check contactors for proper operation and contact point wear

Fan and Motor Inspection

Are fan motors operational?

Ensure fan blades are tight

Run this procedure

Condensing Unit Start-Up Check

Pre-Start Checks

Verify all connections are tight

Check compressor crankcase oil level (if equipped with sight glass)

Ensure proper installation of compressor components

Check that the compressor discharge and suction shut-off valves are open

Control and Safety Adjustments

Ensure all pressure and safety controls are adjusted properly

Is the room thermostat set for normal operation?

Motor and Fan Checks

Run this procedure
