DHL HEATLESS REGENERATIVE DRYER SECTION 7

7.3 DISMANTLING OF THE
DRYER
If the dryer is to be dismantled, it has to be split into
homogeneous groups of materials.
The LED
“SERVICE” of the
SHDC-2100 device
flashes or is on.
The dryer needs maintenance (also refer to
Section 6.6 and Section 7.1), more precisely :
• If the LED “SERVICE” flashes together with the LED , it means that
the inlet filter of the dryer is clogged – replace the filtering element (car-
tridge).
• If the LED “SERVICE” flashes together with the LED , it means that
the outlet filter of the dryer is clogged – replace the filtering element (car-
tridge).
• If the LED “SERVICE” flashes together with both LEDs - the fil-
ter programmed maintenance timer went off – replace the filtering ele-
ments (cartridges).
• If the LED “SERVICE” flashes together with both LEDs
- the
adsorbent material programmed maintenance timer went off – replace the
desiccant bed.
