KEY SYSTEM COMPONENTS

VACUUM HOLDING TANK
SYSTEM

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 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 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 trouble­shooting information.

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.

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.

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.

NORMAL OPERATION

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.

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.

PROPER CLEANING

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
(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.

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

Fig. C

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.
