 FLUSH OPERATION TIMING CHART
 WINTERIZING 
At the end of each season, the VacuFlush toilet system must be winterized for storage. The following procedure should be 
used:
1.  Pump out holding tank.
2.  Thoroughly flush system with fresh water.
3.  Drain freshwater tank.
4.  Add freshwater antifreeze to freshwater tank.
5.  Flush freshwater antifreeze and water mixture through toilet 
and into the waste holding tank. Each installation is different 
so amounts may vary. User discretion is required to assure 
adequate protection.
6.  Turn off electrical power.
      CAUTION:  The use of freshwater antifreeze that contains alcohol will result in damage to your  
sanitation system.  Only use propylene glycol freshwater antifreeze that 
does not contain alcohol.
 PROPER CLEANING – TOILET BOWL AND SEAL
Fig. B
The  VacuFlush  toilet  should  be  cleaned  regularly  for  maximum  sanitation  and  
operational  efficiency.  You  can  clean  it  just  as  you  would  a  household  toilet. 
 
Do not use caustic chemicals, such as drain-opening types, as they will damage 
the seals.
BOWL CLEANING: For stubborn stains, use SeaLand Bowl and Seal Cleaner (Fig. A). 
It’s manufactured especially for use with our VacuFlush toilets. In certain locations where 
water is hard, a build-up of lime may dull the toilet bowl finish. Restore the shine with this 
cleaner. If you cannot find our brand in your area, contact SeaLand Product Customer 
Service for your nearest dealer. If it is not available, you can also use Bar Keepers Friend

cleanser. It is not necessary to vigorously scrub with either product. Please follow label 
instructions.
SEAL CLEANING:  After an extended time, mineral deposits from hard water can build 
up under the edge of the rubber bowl seal, resulting in a slow leakdown of water from the 
bowl. To prevent this mineral build-up, periodically clean under the bowl seal with SeaLand 
Bowl and Seal Cleaner (Fig. B). 
1.  Put Mode switch in SERVICE position. Flush ball will open automatically. 
2.  Apply  cleanser  onto  the  seal  cleaning  tool  (supplied  with  new  toilet),  and  scrub  
under the seal. Make sure to push bristles between bottom of seal and top of flush 
ball surface to scrub all parts of seal that come into contact with flush ball.
3.  Wait 2-3 minutes. 
4.  Pull up on flush handle to let water flow into bowl. Use cleaning tool and water to rinse
