screen board, tightly hang up the spring in the tower.
6) Unscrew the diffuser with a wrench and remove the adsorbent.
7) Replace the adsorbent and install the diffuser. (adsorbent selection: with a
dew-point of -40
℃
,
Ф
3~5mm aluminum trioxide is suggested, while the
dew-point is -70
℃
,
Ф
3~5mm13x molecular sieve can be adopted.)
8) Loosen the spring of the M6
×
100 screw and make sure the adsorbent is
pressed out.
9) Install the dryer step by step.
10) Use soap water for air tightness test. The qualified machine has no leakage.
Note: leakage will lead to pressure and dew-point increase.
