PREVENTIVE MAINTENANCE
The ADH Sirocco automatic air dehydrator requires no preventive maintenance.
All components are designed for a minimal operational life of 15 years at duty
cycles up to 20%. Higher duty cycles may reduce component life.
CORRECTIVE MAINTENANCE
Verifying the performance of the ADH Sirocco requires special equipment,
fixtures, and expertise. Please consult with Environmental Technology Customer
Service before attempting to service or repair an ADH Sirocco unit.
WARNING
Servicing should be performed by qualified personnel. ADH Sirocco dehydrators
contain lethal voltages. Assume that all circuits are live. Attached ADH Sirocco
automatic air dehydrators may produce as much as 24 psig (1,655mbar) under
worst-case failure. Vent the system to the atmosphere before servicing
pneumatic components.
All fittings and hardware are in standard American dimensions, or inches. Use a
solution of mild liquid dish detergent and water to locate air leaks. By
convention, Drying Canister 1 is the drying canister on the left when viewed from
the front of the unit.
CAUTION
Do not apply power to the unit unless all internal connections have been made.
Failure to do this may result in component damage.
