Read all instructions before use or installation.

3 Intended use
The Dometic Vacuum Holding Tank (VHT) brings the powerful ushing performance, convenience
and efciency of VacuFlush®technology to smaller boats (as small as 22 ft./6.7 m) in an easy-to-install
package. VHT units produce and store vacuum for ushing, and also is a waste holding tank with
6.5-gallon/25-liter capacity.
3.1 Features
Combines vacuum pump, vacuum tank and holding tank into one unit. Eliminates plumbing
between vacuum source and holding tank. Complete Type III MSD system for a VacuFlush toilet.
Extremely efficient flushing. Using as little as 1 pint/0.4 liter per ush, the VHT holds as many
ushes as tanks up to three times larger that are connected to standard marine toilets.
“Full” tank probe and automatic shutdown relay. Turns off power when tank is full to prevent over-
ll. “Full” level indicator panel (available separately from Dometic) can be wired to probe.
