INSTALLATION
TMC marine toilets can be installed above or below the waterline.
Inlet and outlet seacock should be easily accessible and be positive shut off valves. If
seacock not be conveniently operated from toilet location, install suitable shut off valves for
inlet and discharge connections.
Surface where toilet is mound should be flat to prevent distortion of toilet base.
Use M8 screws to install through 3 base holes (dia.10mm).
User may rotate it to the desired position by loosening the 3 screws on the flange.
Outlet port can be rotated 360°, user may rotate it to the desired position then fasten it by
the screws.
Fasten all pipe connections with clamps.
Adaptors of 19mm(3/4") & 38mm(1-1/2") are provided for connecting options.

PLUMBING CONNECTIONS
TMC marine toilets may be installed above or below the waterline.
Connect inlet hose using 25mm(1”) ID hose. Make sure all inlet connections are airtight
and free of sharp bends or restrictions.
Connect 25mm(1”) hose to discharge port and make suitable connection to holding tank or
other discharge system. Avoid sharp bends or restrictions.
For above waterline installations, a check valve (optional) may have to be installed in the
flush water intake line to ensure rapid pump priming. To retain water in bowl, make a loop
in the discharge line about 20 cm (8 inches) above base of bowl.
Do not connect inlet hose to a pressurized water system.
If the toilet is, or can be, below waterline at any normal (including static) attitude of vessel
heel and / or trim, a 1” vented loop fitting must be installed in the inlet pipe work. The
vented loop fitting must be positioned so it always remains above the waterline at all angles
of heel and trim.
Vented loops installed below water line are required to prevent backflow of the waste.
The waste can be stored in the holding tank first then discharged to pump out station at the
port.

VENTED LOOPS
25mm(1”) for waste outlet discharge.
25mm(1”) for macerator toilet discharge.
38mm(1-1/2") for waste pump discharge.
25mm(1”) for water inlet discharge.
Vented loops are required for below waterline installations and hose connections must be
double clamped.
Top of the loop must be above waterline.
Intake vented loops must be installed between pump and back of the bowl.
Discharge vented loops must be installed between the discharge of toilet and seacock.
Do not position the vented loops between the in-let sea-cock and the flushing pump inlet.It
will make the flushing pump difficult or harder to prime, and could prevent it from working at
all.
CAUTIONS
Always close sea-cocks when leaving boat unattended.
Always close sea-cocks when toilet is not in use.
Failure to do so may result in flooding which can cause loss of property and life.
Do Not apply flame or heat to hoses.
Do Not apply sealing compounds to any hose connection.
Do Not use thick liquid toilet cleansers or neat bleach because they may damage the
valves, gaskets and seals.
If the toilet is plumbed to the vessels portable water supply you must install an anti-syphon
breaker valve on the toilet inlet pipework to prevent water supply contamination.
Do Not dismantle the product without the help of authorized technician. For any questions,
please contact with your original seller or dealer.
Correct motor polarity (Red to positive (+), Black to negative (-)) is important. Reverse
polarity can damage motor and void warranty. Full voltage at the motor is required to
properly operate the Electric Toilet. The toilet must be wired in a circuit independent of all
other accessories.
The toilet bowl body is made of vitreous china and it’s fragile.
Do Not drop the product from high place or with heavy force.
Please handle the product with care.
