Frequently Asked Questions - SeaXchange SXII 1800Z DOMETIC
How do I install the SeaXchange SXII 1800Z toilet?
Refer to the manual for detailed steps. Generally, mount the toilet to the floor with the provided bolts, connect the 12V power supply (fuse required), attach freshwater intake (3/4" hose) and waste outlet (1-1/2" hose), and prime the pump before first use.
What water supply is needed?
The toilet requires a freshwater connection at 1.5-3 bar pressure. Use a dedicated water line with a shutoff valve. An onboard or dock water system can be used.
How do I adjust the flush water volume?
On the control board, locate the trim pot labeled 'Flush Time'. Turn it clockwise to increase flush duration (and water used) or counterclockwise to decrease. Typical setting: 5-10 seconds.
Why is the toilet not flushing or making unusual noise?
Check the 12V power supply and ensure the circuit breaker is on. If the pump runs but no water, check for air in the intake (prime the pump). If the pump is noisy, it may be jammed; clear the macerator by inserting a screwdriver through the access port.
How often should I clean the filter?
Clean the inline water filter every 3 months or after 50 flushes, whichever comes first. Remove the filter housing, rinse the mesh screen, and reassemble.
What should I do if there is a foul odor?
First, ensure the vent line is clear and check the odor filter (replace if saturated). Use a marine toilet treatment (enzyme-based) in the holding tank. Run a flush with freshwater and a cup of white vinegar monthly to descale.
Can I use the toilet with a seawater intake?
No, the pump is designed for freshwater only. Seawater will cause corrosion and salt buildup, damaging the pump and seals. If only seawater is available, install a separate freshwater flush system.
Where can I find spare parts?
Spare parts are available through Dometic dealers or online. Common replacements include the macerator pump kit (part no. SXII-PMP), seal kit (SXII-SEA), and control board (SXII-CTRL). Use the manual's back cover for part numbers.
How do I winterize the toilet?
Disconnect power and water. Flush with antifreeze (non-toxic marine grade) through the intake hose. Remove the pump cover, drain any standing water from the bowl and pump. Store in a dry environment.
What is the warranty period?
Dometic provides a 2-year limited warranty for manufacturing defects. Registration required. The warranty does not cover damage from improper installation, misuse, or lack of maintenance.
