2) A FLUSH button – Starts an add water and
macerate sequence that runs the motor and adds
water twice for maximum cleansing and minimum
water usage. Sequence ends with a small amount
of water added to the bowl to provide an odor trap.
Recommended to minimize water use and for
liquid waste disposal without adding water.
If toilet is connected to any through-hull fittings,
always CLOSE or TURN OFF all seacocks
when boat is unattended – even if only for a
minimal time.
For units using fresh water that are (at any
time) connected to shoreside municipal water
supply systems, Shoreside system must be
DISCONNECTED if boat is left unattended –
even if only for a minimal time.
Only human waste and toilet paper should be
put into the toilet. Never flush FOREIGN
MATERIALS (e.g. paper towels, pre-moistened
wipes, condoms, feminine hygiene products,
dental floss, household garbage, etc.).
Damage to toilet and/or waste system may
result.
NOTICE
It is important to use a RV/Marine tissue that
disintegrates rapidly, which household tissues
cannot be relied upon to do.
B. Head With Overboard Discharge
This option is available on the V458 models. The head
toilet operations are the same as the systems de-
scribed earlier. A single "wye" connector is incorpo-
rated into the waste holding tank system. See figure
J13. An additional hose with a seacock and discharge
pump has also been installed for overboard discharge.
Refer to Figure J14. Note: A circuit breaker which
protects the discharge pumps circuitry is located on
the 12VDC cabin panel.
