The PURASAN
®
EX is a U. S. Coast Guard Certied Type I Marine Sanitation Device for use on un-
inspected vessels 65 feet and under. It must be operated within navigable waters inside the three mile
limit that are not declared Federal No Discharge Zones (NDZ) by the U.S. Environmental Protection
Agency (EPA). Other countries - check with local authorities.
The PURASAN
®
EX is designed for recreational use and accommodates most marine toilets. The
PURASAN
®
EX is available in 12 or 24 VDC.
DESCRIPTION:
Each time the transfer pump cycles an equal amount of previously treated waste is discharged. The pump-
ing action of the transfer pump moves the waste through the PURASAN
®
EX and out.
Water is diverted to the Tablet Dispenser during the treatment cycle, creating a halogen solution during
hold time. After the hold time, the Drain Manifold and Air Pump turn on and the solution drains into the
Treatment Unit.The rst chamber macerates to reduce particle size and uniformly mix the waste with
injected halogen solution. The second chamber mixes to ensure uniform treatment of its contents.
THE FOLLOWING ARE CAUTIONARY STATEMENTS THAT MUST BE READ AND
