WARNING – HIGH VOLTAGE SYSTEM.

Turn off electrical power before servicing.

WARNING – PUMP STARTS AUTOMATICALLY.

Turn off electrical power before servicing.

KEY SYSTEM COMPONENTS

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

use a small amount of water (a little more than a pint) 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 compart-

ment. EcoVac toilets are equipped with an integral vacuum breaker which prevents the possible contamina-

tion 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 leak down between flushes,

causing the vacuum pump to run for a short period.

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, and handles solids without a problem. It has two duckbill valves on each side

of the pump chamber.

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.

Vacuum Holding Tank: The vacuum holding tank combines the vacuum tank, vacuum pump and

holding tank. Refer to the Vacuum Holding Tank Owner’s Manual (Part No. 343026) for installation and trouble-

shooting information.

VACUUM HOLDING TANK

SYSTEM

SYSTEM START-UP

1. Turn on electrical power to system.

2. Flush water into system by depressing flush lever until water starts flowing to the vacuum pump, approximately

15 seconds. This wets the pump interior for efficient operation. If vacuum pump does not run, check for loose

electrical connections. Refer to the wiring diagram at the end of the Troubleshooting Guide section.

3. The vacuum pump will run for approximately 30 to 90 seconds until system reaches operating vacuum level and

then will shut off.

TOILET OPERATION

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 EcoVac 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 product dealer.

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 bro-

ken 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.

NORMAL OPERATION

The above label is located on the toilet base and will show the model number and serial number. If label is not

available, please refer to the Dimensional Specifications section for toilet model identification.

TOILET MODEL IDENTIFICATION

NOTE: Make sure all guests understand the operation of the EcoVac toilet, and that the instruction label is easy to

read and in plain sight.

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.

The EcoVac 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 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®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. 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.

MAINTENANCE

Maintenance intervals and normal parts replacement vary widely depending on numerous factors such as: type of

vessel, frequency of system use, quality of flushing water, etc. The chart below is intended strictly as a general

guideline. Owner discretion and consideration of actual usage must be the first basis for determining proper

maintenance levels.

*See Base Assembly - Page 7.

VACUUM TESTER

Dometic has developed a simple tool to assist 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 generator isolates the toilet from the

system. In this way a troublesome leak can easily

be located in either system.

Order only the Vacuum Tester (Part Number 530002)

or as part of the complete system maintenance kit

(Part Number 310228).

Vacuum Tester

SERVICE TIP

Checking for leaks behind or under toilets or other appliances can make it difficult to locate the source. Dripping

water at room temperature makes it difficult to feel wetness. Taking four or five sheets of toilet tissue and wiping all

seams and waterline connections offers a simple means of locating the general area of the leakage. Start at the top

of the unit since gravity will cause a leak to run downward. When the tissue comes in contact with the leaking

water, it will immediately change texture.

Maintenance Procedure

Follow cleaning procedures above.

Tighten all clamps, including base clamp ring.*

Check all wire connections.

Check & tighten water valve mounting screws.

Clean filter screen in water valve.

Check pump and in-line valves.

Check toilet seals.

Check vacuum breaker.

Check water valve.
