KEY INSTALLATION POINTS

The VacuFlush system operates on a unique and un- common principle – powerful, instantaneous vacuum force. As a result, certain installation points must be stressed because they are the most common sources of incorrect installation.

1. Leaks at Fitting Joints

One benefit of vacuum operation is that leaks are inward and will not cause drippage of sewage. Vacuum leaks result in frequent cycling of the vacuum pump which causes unnecessary wear on the motor and gear drive. Most vacuum leaks occur at fitting joints. Care should be taken to assemble fitting joints per the instructions. Allow time in your installation schedule to give cemented fittings, if used, time to cure before manipulating them. Also, a proper PVC cleaner or primer must be applied prior to cementing fittings.

2. Cementing Hose to Fittings

Never cement hose to fittings. The SeaLand custom hose adapter is specifically designed to fit precisely into the OdorSafe Hose. The hose will slide easily on the fitting if it is lubricated with liquid dishwashing detergent and twisted clockwise when attached.

3. Locating Components in Accessible Spaces

Never locate a component of the vacuum system in a space which is inaccessible or difficult to reach.

4. Hose…Too Much, Too Little

Try to avoid unnecessary hose runs that result in excessive bends or loops. Excessive hose reduces vacuum transfer efficiency. Hose should be securely tied down every three feet. Too little hose length also causes problems by forcing the hose into tight bends or kinks. Always leave a small amount of extra hose length for future maintenance. The distance between the toilet and the Vacuum Holding Tank (VHT) may not exceed 20 feet (6.1 m).

5. Hose… Wrong Type

To complete a VacuFlush installation, OdorSafe Sanita- tion Hose or rigid PVC pipe (Schedule 40 or heavier) must be used.

6. Hose… Odor Permeation

Avoid low spots in hose or sections where waste will remain for very long periods. Waste trapped in hose will produce gases in the final stage of decomposition that are very difficult to contain. If possible, have hose from the toilet drain into the VHT.

7.Protecting Toilet and Preventing Objects from Falling into System During Installation.

After mounting toilet and attaching seat and lid assem- bly, slide seat assembly carton over seat and lid. Next, place toilet box down over toilet. This will ensure addi- tional protection to the toilet after installation.

Failure to follow recommended procedures that result in any of the above problems will invalidate component warranty.
