Instrument Dryer Operational Procedure

 Operational Procedure:

1.  Make sure all valves are in proper position.

2.  Check the low refrigeration pressure gauge, it should indicate higher than 0∙4 Mpa (g)/(4∙1 Kg/cm²).

3.  If the voltage is at normal range, open electric control box and close air switch.

4.  Press the control button “ON” to start.

5.  Take note of refrigerant gauge indication at normal range. The low refrigeration pressure gauge should indicate 0∙4~0∙55 Mpa (g) / (4∙1 Kg/cm² ~ 5∙6 Kg/cm²). If pressure is below this range, take necessary steps.

6.  The high refrigeration pressure gauge should indicate 1∙4~2∙5 Mpa (g) / (14∙3 Kg/cm² ~ 25∙5 Kg/cm²). If the indication falls below this range, check and adjust fan motor high and low pressures setting value.

7.  Do not start up and shutdown frequently, Dryers should restarted after 6~10 minutes.
