Use only clean, dry air.
PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush
the chemical out of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical
strainer and replace if missing.
