Maintenance Recommendations - Sullair SAR024 User Manual

Using by-pass line
Close the dryer outlet valve whilst simultaneously opening the by-pass valve.
Close the dryer inlet valve.
The air will now by-pass the dryer, allow the dryer to depressurise before isolating electrical supply, vent
pressure from inlet and outlet filters using methods described in the filter User Guide. The dryer may still
be pressurised if this is not done.
Without by-pass line
Close the dryer outlet valve.
Close the dryer inlet valve
Allow the dryer to depressurise before isolating electrical supply, vent pressure from inlet and outlet filters
using methods described in the filter User Guide. The dryer may still be pressurised if this is not done.

7. MAINTENANCE RECOMMENDATIONS

Daily
Ensure yellow "POWER ON" LED is not flashing.
Visually check crystals in sight glass moisture indicator for blue colour.
Weekly
Check dryer seals, fittings and pipe work for air leaks
Check inlet and outlet filtration for indication of element blockage (see User Guide for Filters)
Ensure correct operation of filtration condensate drainage (if applicable).
The desiccant material in the dryer has a finite life dependent upon operating conditions but it will typically
exceed 10,000 hours use before it needs replacing. It will also require replacing if contaminated. Care
must be taken prior to any routine pipe flushing operations.
The outlet sight glass moisture indicator requires replacing once the crystals are no longer blue. A service
kit is available.
Desiccant changes, service kits and service training courses are available for the SAR range of dryers on
request. Service kits must only be used by Sullair trained personnel.
Only Sullair trained personnel can remove the covers on the dryer.
