“off” position and the vacuum must be allowed to recharge

before another flush cycle can be initiated. A full holding tank will also prevent the toilet from flushing.

3. Selecting Automatic Water Refill Levels:

The Water Level switch is located under the access cover. Carefully lift up on the front of the cover to access the Water Level switch. There are three water refill levels available. The microprocessor-controlled water valve will refill the toilet bowl according to your water level selection.

To reinstall the access cover, set the cover on top of the toilet and press down. This will lock the cover in place and prevent it from coming loose during travel.

LOW Level

Use this setting to conserve water. This position reduces the chance of water splashing out of the bowl during rough travel. If more water is needed for flushing, lift up on the flush handle. Water flow will stop after nine seconds to prevent overflow.

MID Level

ACCESS COVER

CONTROL SWITCHES

Use this position to keep the toilet bowl clean, especially when family and friends may be using the toilet. If more water is needed for flushing, raising the flush handle will provide up to six seconds of refill time.

HIGH Level

Use this position if the MID level does not provide a clean toilet bowl. This position is not recommended while underway. If more water is still desirable for flushing, raising the flush handle will provide up to three seconds of additional water refill time.

4. Mode Switch

The Mode switch is located on the right side of the control module. It switches between three function settings:

NORMAL

Use this setting for flushing the toilet.

SERVICE

Use this position for cleaning the toilet bowl and flush ball seal. The flush ball will open automatically and remain open in this position. Lifting up the flush handle provides water.

MANUAL OVERRIDE

Use this position to flush the toilet manually in the event of power or battery failure. This switch disconnects the electronic brake in the flush valve motor, and allows manual flushing via the override access hole in the side of the vitreous china base.

Note: The control module allows 15 seconds of water for cleaning. If more water is required, return the switch to the NORMAL position then back to the SERVICE position.

A safety circuit in the control module monitors flush ball operation. If foreign objects or low voltage prevent the flush ball from closing, this circuit prevents personal injury or damage to the flush valve motor. If this condition occurs, reset the control module by placing the Mode switch into the SERVICE position temporarily, then returning it to the NORMAL position.

PROPER CLEANING – TOILET BOWL AND SEAL

The VacuFlush 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 Bowl and Seal Cleaner (Fig. A). It’s manufactured especially for use with our VacuFlush toilets. In certain locations where water is hard, a build-up of lime may dull the toilet bowl finish. Restore the shine with this

cleaner. If you cannot find our brand in your area, contact SeaLand Product Customer

Service for your nearest dealer. If it is not available, you can also use Bar Keepers Friend® Fig. A cleanser. It is not necessary 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.Put Mode switch in SERVICE position. Flush ball will open automatically.

2.Apply cleanser onto the seal cleaning tool (supplied with new toilet), 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.

Fig. B

3.Wait 2-3 minutes.

4.Pull up on flush handle to let water flow into bowl. Use cleaning tool and water to rinse

away cleanser and loosened deposits. You can add water for up to 15 seconds in the SERVICE position.

5.Put Mode switch in NORMAL position. Water will flow for a few seconds, then flush ball will close automatically. Water will continue flowing into bowl, making it ready for the next flush.

WINTERIZING

At the end of each season, the VacuFlush toilet system must be winterized for storage. The following procedure should be used:

1.	Pump out holding tank.	5.	Flush freshwater antifreeze and water mixture through toilet
2.	Thoroughly flush system with fresh water.		and into the waste holding tank. Each installation is different
3.	Drain freshwater tank.		so amounts may vary. User discretion is required to assure
4.	Add freshwater antifreeze to freshwater tank.		adequate protection.
		6.	Turn off electrical power.

CAUTION: The use of freshwater antifreeze that contains alcohol will result in damage to your sanitation system. Only use propylene glycol freshwater antifreeze that does not contain alcohol.

4

CLEARING DISCHARGE LINES

Sanitation hoses should be cleared if toilet will not be needed for an extended period of time (more than two weeks).

1.Fill toilet bowl with water and add 4 oz. (120 ml) of biodegradable laundry detergent (should NOT contain bleach).

2.Flush toilet, holding pedal down for about two minutes. Close flush ball.

3.Turn off water supply to toilet.

4.Flush the toilet without water, allowing the vacuum pump to shut off after the flush. Repeat three times. (This procedure will minimize any remaining water in the sanitation hoses.)

5.Turn off power to the vacuum pump.

6.Completely pump out holding tank.

If system will be subjected to freezing temperatures, please follow above procedure, then winterize system as described in this manual.

SANITATION SYSTEM COMPONENTS

VacuumToilet: VacuFlush all-ceramic vacuum toilets with FlushandForget® technology operate differently compared to other toilets.The vacuum system uses 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. Most VacuFlush toilets are equipped with an integral vacuum breaker which prevents the possible contamination of the freshwater supply.

Flush/Add Water Switches (3100, 3400 models only):

Wall-mounted push-button switches provide electronic operation of flushing and adding water to the toilet bowl. Models include two-light vacuum status panel indicating the toilet is “OK to Flush” or “Do Not Flush”. Models vary.

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 betweenthetankandpump.Theircompactsizemakesthem especially well-suited to smaller installation spaces.

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.

Vacuum Pump: The vacuum pump is an electric, straight-through bellows type. It is manufactured of longlasting 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 maintain vacuum and prevent backflow of waste.

“Tank Full” Shut-Down Switches (RV option only):

These “Tank Full” micro-float switches shut down the vacuum generator when the waste holding tank is full. We offer three styles to accommodate various installation requirements.

Sealing grommet style – Item number 900101 MPT style – Item number 900100

Vent style – Item number 900102

SANITATION SYSTEM COMPONENTS (cont’d)

TankWatch® Level Indicator (marine option only):

The TankWatch unit utilizes micro-float switches which activate an indicator panel. The micro-float switches are installed in the top of the holding tank. The adjustable probe assemblies are flexible polybutylene tubing and are designed to flex when tank contents move.

VacuStat™ Indicator Panel: Continuously monitors vacuum status for proper toilet operation. Brushed metallic finish complements bathroom decor. Item number 700112 (12VDC).

Vacuum Status Panel (optional): A two-light status panel indicates the system is “OK to Flush” or “Do Not Flush”. The green “OK to Flush” light is illuminated when there is adequate vacuum pressure available and when the holding tank is less than full. Item number 710012.

VacuFlush Status Panel (optional): Includes two-light status panel indicating the system is “OK to Flush” or “Do Not Flush”, and circuit breaker to shut down system at night. Item number 500012 (12 VDC) or 500024 (24 VDC).

Vacuum Generator Shut-down Relay (standard on RVs; marine option): This relay can automatically shut down power to the VacuFlush toilet system to prevent overfilling of the holding tank. Item number 310289 (12 VDC) or 310290 (24 VDC).

Vacuum Tester (optional): This tool assists in identifying the location of vacuum leaks. The vacuum tester consists of a vacuum gauge and a cone-shaped plug. Inserting the plug in the inlet of the vacuum tank or vacuum generator isolates the toilet from the system. In this way, a vacuum leak can easily be located in either system. Item number 530002.

In-Line Vent Filter (marine option only): The SaniGardTM vent filter has special odor-removing filter materials to help keep your vehicle smelling clean and pleasant. Heavier- than-air malodors accumulate in the holding tank. This 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.

Holding Tanks (marine option only – not shown):

SeaLand holding tanks are made of super-strong, 3/8” (10mm) thick polyethylene — 50% thicker than most other holding tanks. Each features solid, one-piece construction with no seams for unmatched durability. A deodorant additive is recommended to keep the holding tank odor-free. See Deodorants and Special Tissue section for further information (page 8).

DEODORANTS AND SPECIAL TISSUE

Your VacuFlush toilet and sanitation system require 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 Dry: 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, 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.

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

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 vacuum sanitation system, when installed in a boat, 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.

Sewage from any source should not be discharged directly into our waters. If you are interested in learning more about this issue, please contact Dometic at the phone number or address listed on the back page of this manual.
