3. Pull flush handle to open slide valve.

4. Pour deodorant directly into lower tank, then close slide valve.
   CAUTION! Never pour deodorant into bowl with slide valve closed.

   CAUTION! Do not over-pressurize upper tank by covering relief valve. Do not pressurize upper tank when disconnected from lower tank.

DOMETIC CORPORATION ACCEPTS NO RESPONSIBILITY OR LIABILITY FOR DAMAGE TO EQUIPMENT, OR INJURY OR DEATH TO PERSONNEL THAT MAY RESULT FROM IMPROPER INSTALLATION, SERVICE OR OPERATION OF THIS PRODUCT.
• HAZARD OF FLOODING  If the toilet system is connected to ANY through-the-hull fittings, properly installed seacocks MUST be installed in all piping connected to through-the-hull fittings. Seacocks MUST be easily accessible to all users of the toilet system or secondary valves fitted in hoses where they are easily accessible. ALWAYS close seacocks when toilet system is not in use (even if boat is unattended for a brief period. All valves MUST be full bore valves and marine quality. Screw-to-close gate valves are not recommended. Failure to comply can result in flooding which can cause loss of property and life.HAZARD OF FLOODING – If the toilet system is connected to ANY through-the-hull fittings, properly installed seacocks MUST be installed in all piping connected to through-the-hull fittings. Seacocks MUST be easily accessible to all users of the toilet system or secondary valves fitted in hoses where they are easily accessible. ALWAYS close seacocks when toilet system is not in use (even if boat is unattended for a brief period. All valves MUST be full bore valves and marine quality. Screw-to-close gate valves are not recommended. Failure to comply can result in flooding which can cause loss of property and life.
• HAZARD OF FLOODING – If toilet is connected to ANY through-the-hull fittings, ALL flexible hoses must be of marine sanitation qual-ity and must be secured to ANY fittings (such as those at seacock, vented loop or toilet) with two stainless steel, worm-drive hose band clamps at each connection. Connections MUST be checked frequently for integrity. Failure to comply can result in flooding which can cause loss of prop-erty and life.
• HAZARD OF FLOODING – If toilet rim is below the waterline at ANY time (during any conditions of heel, load or trim) and is con-nected to ANY through-the-hull fittings, properly positioned ventilated (vented) loops MUST be installed in discharge piping to prevent potential back siphonage of seawater into the boat. Failure to do so can result in flooding which can cause loss of property and life.

PLUMBING SPECIFICATIONS

MARINE SANITATION REGULATIONS
All boats with fixed toilets in U.S. waters and in the waters of some other countries are required to have an operable, permanently installed marine sanitation device (MSD). Series 970 MSD models, when permanently installed in a boat, are holding tank or Type III systems as defined by the U.S. Coast Guard. Type III systems permit opera-tion of the toilet without direct discharge of untreated waste after every flush. Type III systems can be discharged at marina dockside pump-out stations or, if in coastal waters, a minimum of three miles offshore. Overboard discharge capability must remain secured while within the three-mile limit. If an overboard discharge pump is activated by a keyed switch in the toilet compartment, the key must be removed at all times except when discharge pump is operating and in the process of vessel operation. Sewage from any source should not be discharged directly into our waters. If you are interested in learning more about this issue, please visit our website at www.DometicSanitation.com.

This symbol appears on the discharge fitting of MSD models.

CLEANING AND MAINTENANCE

Cleaning
For most effective cleaning, use SeaLand® Toilet Bowl Cleaner. It’s intended for use with all Dometic toilets. If you cannot find it in your area, contact Dometic for your nearest dealer. If it is not available, you can also use most non-abrasive bathroom and toilet bowl cleaners (Bar Keeper’s Friend® spray cleaner, Clorox® toilet bowl cleaner, SaniFlush® toilet bowl cleaner, etc.). Follow label instructions.

Maintenance
If flush handle becomes difficult to pull, lubricate slide valve seals with silicone spray.

WINTERIZING

Use
When using the Dometic portable toilet in cold or winter weather, the addition of nontoxic anti-freeze designated for potable water systems provides safe winter protection. Use amounts specified on container that are safe for use with 4 gallons (15 l) of water.
NOTE : Never use alcohol-based or automotive-type antifreeze in freshwater systems.

Storage
To store Dometic portable toilet during the winter:

1. Empty freshwater tank and holding tank.
2. Make sure all water is cleared from freshwater tank’s water lines by pressurizing tank and pushing flush button until no water enters bowl.
   A small amount of water may remain in bottom of freshwater tank but will be harmless during winter storage.)
