INSTRUCTIONS MANUAL

Proceed as follows:

“REFRIGERANT AVAILABLE” LED must light, if it is necessary press the SEL key to switch the light to “REFRIGERANT AVAILABLE” LED.

1.Press once the “°F” key in order to display the refrigerant tank temperature (in Fahrenheit degree), press it a second time to display the temperature in Celsius degree)

2.Read the storage tank pressure of the tank gauge

3.Find the temperature in the TEMP °F column for that tank then read the associated PRESSURE column in psig.

4.If the related TANK PRESSURE gauge (A4, fig.5) reads LOWER or EQUAL than the nominal pressure listed in the table for the respective tank temperature, IT IS NOT NECESSARY to vent the non-condensable gases from the tank.

5.If the related TANK PRESSURE gauge (A4, fig.5) reads HIGHER than the nominal pressure listed in the table for the respective tank temperature, you should vent the non-condensable gases from the tank. This is accomplished by opening the air purge valve as shown in figures 1,2,3, & 4.

6.Press the STOP keyto exit the reading of the tank temperature

7.Slowlyopen the air purge valve (r,fig.2) counterclockwise (turn ~20 degree)

8.Once opened the air purge valve r, (fig.2) check the tank pressure gauge and the value shown bythe display.

9.Close the air purge valve when the tank pressure comes down to the nominal pressure listed in the table.
