MARINE SANITATION REGULATIONS

All boats with fixed toilets in U.S. waters and in the waters of some other countries are required to be equipped with an operable marine sanitation device (MSD). The VacuFlush system is a holding tank or Type III system as defined by the U.S. Coast Guard.

Type III systems are designed to permit operation of the toilet without the direct discharge of untreated waste after every flush. This means onboard toilet facilities can be used when the boat is near swimmers, beaches or shellfish beds.

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. The overboard discharge pump is activated by a keyed switch located in the toilet compartment. This key should be removed at all times except when discharge pump is operating.

Federal legislation has provided grants to private marinas to install dockside pumps especially in coastal water. It is estimated that over 3,500 pump-out stations, in total, will be added due to this legislation.

Sewage from any source should not be discharged directly into our waters. If you are interested in learning more about this issue, please contact SeaLand at the phone number or address listed on the back page of this manual. Request Clean Water Notebook, Volumes 1 and 2.

IMPORTANT INFORMATION BEFORE OPERATION

1. Fill freshwater tank and add deodorant to holding tank through toilet bowl. (See System Start Up Section)

2. Make sure all guests understand the operation of the VacuFlush system and the instruction label is in plain sight and easy for guests to read.

If this label is not included in this manual, please contact the SeaLand Product Customer Service Department immediately.

3. Remember the vacuum pump starts automatically. Shut off the system before servicing and do not leave the boat with toilet system breaker on.

4. Never use drain openers, alcohol, solvents, etc. in the system.

5. If the system does not function properly, refer to the Troubleshooting Section of this manual and repair as necessary. If problem persists, contact your local SeaLand dealer or see the Parts Distributor section of this manual.

NORMAL OPERATION

1. To add water to the toilet before using, raise flush lever until desired water level is reached. Generally, more water is required only when flushing solids.

2. To flush toilet, press flush lever sharply down to the floor until contents clear bowl. A sharp popping noise is normal when the vacuum seal is broken and flushing action begins. Be sure to hold lever down for three (3) seconds. If flush lever is accidentally released before waste clears bowl, do not attempt to flush toilet again until vacuum pump stops running. A small amount of water should remain in the bowl after flushing.

3. Do not dispose of sanitary napkins or other non-dissolving items in toilet, such as facial tissue or paper towels. These items can cause plugging of the system. Refer to the Deodorants and Special Tissue section in this manual for more information.

KEY SYSTEM COMPONENTS

Vacuum Toilet: The VacuFlush toilet operates in a way different from other marine toilets. VacuFlush systems use

a small amount of water (a little more than a pint or .5 liter) per flush in addition to a simple vacuum. The toilet is connected to a pressurized freshwater system. Fresh water is the key to an odor-free bathroom compartment. VacuFlush toilets are equipped with an integral vacuum breaker which prevents the possible contamination of the potable water supply.

Vacuum Tank: The vacuum tank stores vacuum energy. System vacuum level is monitored by a vacuum switch located on the vacuum tank. When this switch senses a drop in vacuum in the system, it automatically signals the pump to energize and bring the vacuum to operating level. This process is normally completed in less than one minute. In a properly operating system, the stored vacuum will slowly dissipate between flushes, permitting the vacuum pump to quickly renew the vacuum.

Vacuum Pump: The vacuum pump is an electric, straight-through bellows type. It is manufactured of long-lasting polypropylene and draws only 4 to 6 amps of current at 12 VDC. This unique pump design is both an efficient air and liquid pump that handles solids without a problem. It has two duckbill valves on each side of the pump chamber to prevent backflow of waste and vacuum.

Vacuum Generator: The vacuum generator combines the vacuum tank and vacuum pump in one unit. It greatly reduces installation time and eliminates the hose run between the tank and pump. Its compact size makes it especially well-suited to smaller crafts.

Holding Tanks: Holding tanks from Dometic are made of super-strong, 3/8" (9.5mm) thick polyethylene — 50% thicker than most other holding tanks. Each unit has a solid, one-piece construction with no seams for unmatched durability. Tanks come in several capacities and shapes. Contact Dometic for details. A deodorant additive is required to keep the holding tank odor-free. See Deodorants and Special Tissue section for further information.

TankWatch

The inspection cap in the holding tank contains the micro-float switch units. The adjustable probe assemblies are flexible polybutylene tubing and are designed to flex when tank contents move.

In-Line Vent Filter: Our SaniGard smelling clean and pleasant. Heavier-than-air malodors accumulate in the holding tank. The SaniGard vent filter has a special type of activated filter media to remove these odors before they offend. Each cartridge is good for an entire season, and is easily replaced for a fresh start. Replacement cartridges are available from your local marine dealer.

Dockside Discharge Deck Fitting: The holding tank is connected to a deck discharge fitting. This fitting, in turn, can be connected to a dockside pump which may have a rubber, cone-shaped nozzle or a cam lock fitting. Refer to Accessories section for further information on the NozAll™ fitting which makes using a dockside pump easy and convenient.

Discharge Pump: Our T-series SaniPump VDC. The discharge pump has a flow rate of just over 5.25 gallons per minute (11.4 liters per minute). Emptying an onboard tank usually takes four to six minutes. The T-pump is connected to a through-hull fitting. Check the section on Marine Sanitation Regulations for information on areas where discharge is allowed.

Level Indicator: The TankWatch unit utilizes micro-float switches which activate an indicator panel.

SYSTEM START UP

1. Turn on inlet water supply.

2. Turn on electrical power to system.

3. Flush water into system by depressing flush lever until water starts flowing to the vacuum pump, approximately 15 seconds. The vacuum pump will run for approximately 60 to 90 seconds until system reaches operating vacuum level and then will shut off.

PROPER CLEANING

The SeaLand toilet should be cleaned regularly for maximum sanitation and operational efficiency. You can clean it just as you would a household toilet.

Do not use caustic chemicals, such as drain-opening types, as they will damage the seals.

BOWL CLEANING: For stubborn stains, use SeaLand Cleaner (Fig. A). It’s manufactured especially for use with SeaLand toilets. In certain locations where water is hard, a build-up of lime may dull the toilet bowl finish. Restore the shine with this SeaLand cleaner. If you cannot find it in your area, contact SeaLand for your nearest dealer. If the cleaner is not available, you can also use Bar Keepers Friend sary to vigorously scrub with either product. Please follow label instructions.

SEAL CLEANING: After an extended time, mineral deposits from hard water can build up under the edge of the rubber bowl seal, resulting in a slow leakdown of water from the bowl. To prevent this mineral build-up, periodically clean under the bowl seal with SeaLand Bowl and Seal Cleaner (Fig. B).

1. Shut off water supply.

2. Apply cleaner onto the seal cleaning tool (supplied with new toilet), open the flush ball by pressing on flush lever, and scrub under the seal. Make sure to push bristles between bottom of seal and top of flush ball surface to scrub all parts of seal that come into contact with flush ball.

3. Close ball and wait 2-3 minutes.

4. Open flush ball. Use brush and water to rinse away cleanser and loosened deposits.

WINTERIZING

At the end of each season, the SeaLand toilet should be winterized for storage, by either draining or using potable water-safe antifreeze in the system.

To drain:

1. Thoroughly flush system with fresh water.

2. Empty holding tank.

3. Shut off water supply to toilet(s), and remove inlet waterline (Fig. C).

Do not remove brass cap on bottom of valve.

4. Press flush lever until all water is drained from toilet(s).

To use antifreeze:

1. Drain potable water tank.

2. Add freshwater antifreeze to potable water tank.

3. Flush potable water antifreeze and water mixture through toilet(s) and into the waste holding tank. Each installation is different, so amounts may vary. User discretion is required to assure adequate protection.

4. Empty holding tank.

NOTE: Use nontoxic antifreeze designated for potable water systems. (See vehicle owner’s manual.) CAUTION: Never use automotive-type antifreeze in freshwater systems.

4. Attach pedal cover side plate and secure with two (2) mounting screws. For short base units, secure front screw, then press foot pedal down completely to secure second screw.

DEODORANTS AND SPECIAL TISSUE

Your VacuFlush sanitation system requires the regular addition of a deodorant product to reduce malodors and to help break down holding tank contents. Several factors should be considered in selecting a deodorant product.

Liquid or Granulated: Liquid products obviously work more quickly by readily going into solution. Granulated powder formulations, on the other hand, have the advantage of requiring less storage space and are less likely to leak if the package is inadvertently damaged.

Formaldehyde versus Non-Formaldehyde: Dometic manufactures both types of deodorants. Generally speaking, formaldehyde formulas control odor very effectively at all temperatures and with all degrees of water hardness. SeaLand Environment-Friendly brand, which is formaldehyde free, is similarly effective.

Environmental Hazards: If you would like further information on the impact of holding tank deodorants, call or write Dometic at the number and address listed on the back page of this manual. Request a copy of Clean Water Notebook, Volume 5, which provides complete information in this regard.

How Much Deodorant and How to Add It: The deodorant is added directly into the toilet bowl, then flushed into the holding tank. Follow bottle or package instructions. Conditions of extremely warm weather, longer waste holding time and larger tank capacities may require more deodorant treatment. Also, to maintain optimum efficiency in odor control, the waste holding tank should be cleaned thoroughly at least once or more each season depending on use.

Why Not Use Household Toilet Paper in Your SeaLand Toilet. Household tissues often contain adhesives which bond together the paper fibers from which the tissue is made. The adhesives prevent the tissue from breaking apart, and their use in “ultra-low flow” systems can cause system clogging. SeaLand tissue is especially designed for use in low water toilet systems. Its rapid dissolving properties minimize the amount of residual paper in the holding tank and allow deodorizers to work more efficiently.

SeaLand versus Other Brands: Dometic constantly strives to provide our system owners with effective products that have minimal environmental impact and good value. Many other deodorant products do not measure up to our standards of performance and value.
