VACUUM TOILET OPERATION
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.
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 bro-
ken and flushing action begins.
Be sure to hold lever down for three
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. Refer to the Deodorants and
Special Tissue section in this manual
for more information.
HOLDING TANK OPERATION – DISCHARGE
1. Position vehicle close to sewage dumping facility.
2. Unroll discharge hose, remove plastic cap, and insert end into dumping facility.
3. Activate discharge pump.
4. After tank is empty, the tank can be rinsed. (Note: Rinsing systems vary by vehicle. Consult vehicle dealer.)
5. Discharge rinse water into dumping facility. Drain all water from discharge hose. Put plastic cap on end of hose.
Roll up and store hose.
WINTERIZING – HOLDING TANK
If using antifreeze to winterize the holding tank system, use only propylene glycol freshwater antifreeze that does not
contain alcohol. Antifreeze that contains alcohol will result in damage to your sanitation system.
1. Pump out holding tank.
2. Thoroughly flush the system with fresh water before adding propylene glycol freshwater antifreeze to the HTS.
3. Turn off electrical power.
CLEANING – HOLDING TANK
A small amount of water remains in all holding tanks. It is good practice to rinse the tank after the contents have been
discharged. This can be accomplished by adding water to the toilet bowl. Add 237 ml (8 oz.) of SeaLand
®
Holding
Tank Deodorant to the bowl. Flush the entire contents into the holding tank and continue flushing until the discharge
from the holding tank is clear.
Do not use chlorine-based cleaners, caustic cleaners or chemicals, such as drain-opening products, as they
may damage the system’s seals and hose.
