OPERATING INSTRUCTIONS
To properly use the SeaLand toilet, follow these simple
instructions:
1. A good biodegradable tissue such as SeaLand®brand
is recommended.
2. To add water to the toilet before using, lift or raise
the ush pedal.
3. To ush toilet, push pedal all the way down until
sewage leaves the toilet bowl. Water ow pressures
vary at different locations and therefore, holding the
ush lever down 4-8 seconds may be required. We
recommend 2-4 GPM (8-15 Lpm) for proper rim and
bowl wash.
4. Release ush pedal by allowing it to snap back, which
permits positive sealing around the ush ball.
5. A small amount of water should remain in the bowl.
Note: Holding the ush pedal down longer than neces-
sary results in excessive water usage.
CAUTION: Do not dispose of sanitary napkins or other
non-dissolving items in the toilet.
MAINTENANCE
CLEANING
The SeaLand toilet should be cleaned regularly for maxi-
mum sanitation and operational efciency.
Clean the toilet bowl with a mild bathroom cleaner,
such as SeaLand®Bowl and Seal Cleaner. Do not use
chlorine or alcohol-based caustic chemicals such as
drain opening types, as they will damage the seals.
If an odor is apparent from the toilet:
1. Clean out system by ushing several gallons of fresh
water through with one cup of liquid laundry soap.
2. Add odor control deodorant in amount specied for
your holding tank capacity after cleaning and every
few days during use.
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 ush system with fresh water.
2. Empty holding tank.
3. Shut off water supply to toilet. Remove inlet
waterline.
4. Press flush lever until all water is drained from
toilet.
