4 MAINTENANCE
NOTICE RISK OF PROPERTY DAMAGE: Do not use abrasive cleaners, caustic chemicals, or lubricants and cleaners that contain alcohols or petroleum distillates. These substances may cause damage to the toilet's internal seals.
4.1 Cleaning the toilet
Use non-abrasive cleaners to maintain the original appearance of the toilet.
4.2 VacuFlush system maintenance
Maintenance procedures vary widely and depend on factors such as frequency of use, quality of flushing water, etc. The chart provides a general guideline for keeping your toilet system ready for use at any time.
Maintenance Procedure Service Interval Notes
| ROUTINE | ||
| Check all clamped hose joints below water line for leaks | Monthly — | |
| Check filter screen in water valve | After first year of service, then as needed if water flow is noticeably slower | Screen is located inside water valve inlet |
| Replace vent filter (if installed in holding tank vent line) | Annually — | |
| MAJOR SYSTEM MAINTENANCE | ||
| Replace duckbill valves in vacuum generator or vacuum pump | Every three years See vacuum generator or vacuum pump parts list for replacement kit part number | |
| Replace flush ball seal and flush ball (if required) | Every three years See toilet parts list for replacement kit part number | |
4.3 Recommended spare parts
When operating a boat or other vehicle in remote areas, keep the following spare parts on hand to assure continuous toilet system operation.
| Description Where Used | |
| Flush ball seal | VacuFlush toilet (see parts list) |
| Flush ball | VacuFlush toilet (see parts list). |
| Electric water valve | VacuFlush toilet (see parts list) |
| Vacuum switch kit | Vacuum tank or vacuum generator (see parts list) |
| Duckbill valves | Vacuum tank or vacuum generator (see parts list) |
To order spare parts, refer to "7 Customer Service" on page 16
4.4 Clearing blockage in toilet base
Turn off water to the toilet.
Open the flush ball in Service Mode.
Pull the foreign material from the one-inch diameter orifice at the bottom of the base or, using a small diameter blunt rod, attempt to push the blockage through the orifice.
4.5 Locating potential vacuum leaks in base assembly
The VacuFlush toilet is part of a vacuum system that includes a vacuum pump and vacuum tank, or a vacuum generator and discharge plumbing lines. If a vacuum leak is suspected, special equipment will isolate the source of the leak. If the toilet is determined to be the source of the leak, there are three possible areas to investigate:
Flush ball and flush-ball seal. See "Water does not stay in toilet bowl (leaks between flush ball and seal)" on page 12.
O-rings on the rotor shaft.
O-rings around the bottom of the toilet base assembly.
Sources 1 and 2 will require the base assembly to be removed from the toilet and partially disassembled.
4.6 Preparing the toilet for an extended period of non-use
Toilet system sanitation hoses should be cleared if the toilet will not be used for more than two weeks.
Flush the toilet in Normal Mode.
Add 4 oz. (120 ml) of liquid biodegradable laundry detergent. The detergent should not contain bleach or other environmentally harmful substances.
Open the flush ball in Service mode. Hold the Add Water switch down for about two minutes.
Release the Add Water switch and return the Service Mode switch to the Normal position.
Turn off the water supply to the toilet.
Flush the toilet without water, allowing the vacuum pump to shut off after the flush. Repeat three times. (This procedure will minimize any remaining water in the sanitation hoses.)
Turn off power to the vacuum pump.
Completely pump out the holding tank
If the system will be subjected to freezing temperatures, please follow the above procedure, then proceed to "4.7 Winterizing the toilet" on page 8.
If people will not be using the boat or RV for an extended period of time (vacation, maintenance, off-season, etc.), or in the event of a long electrical power interruption, electrical power and water supply to the toilet and the vacuum generator should be shut off.
4.7 Winterizing the toilet
WARNING RISK OF POISONING: Do not use an automotive-type antifreeze in fresh-water systems. Failure to comply could result in property damage, serious injury, or death.
The amount of antifreeze needed may vary, depending on the installation.
At the end of each season, the VacuFlush toilet system should be winterized for storage. The following procedure should be used:
Thoroughly flush the system with fresh water.
Drain the potable tank.
Empty the holding tank.
Add potable-water antifreeze to the freshwater tank.
Flush the potable-water antifreeze and water mixture through the toilet and into the entire plumbing system. Each installation is different, so amounts may vary. User discretion is required to assure adequate protection.
Turn off power to the toilet and all other vacuum system components.
Empty the holding tank of any remaining contents.
