Intended use SailVac Vacuum Holding Tank
3 Intended use
The SailVac™ VHT 5200 series vacuum holding tank provides a 14-gallon (53 liter) capacity
holding tank with built-in vacuum-generating capability for exclusive use with any VacuFlush toilet .
The holding tank is specially shaped to install in the outboard space of a typical sailboat head .
By virtue of the extreme low water use of VacuFlush toilets, the VHT 5200 provides enough holding
tank capacity for two people for four days .
3.1 Features
Odor-proof toilet system operation. Vacuum action keeps toilet discharge line clear of effluent
to prevent possible hose permeation of odor . Heavy-wall polyethylene tank prevents odor
permeation and corrosion .
Leakproof performance. Vacuum holding tank fittings are connected on top of the tank, eliminating
the possibility of leaking due to faulty connections below the level of the tank contents .
As little as 1 pint (0.5 l) water consumption per flush. Extends freshwater tank supply . Holds three
times more flushes between pump-outs than standard electric marine toilet systems.
Energy efficient. Draws only 3 amps per flush (12V DC).
“3/4” and “full” tank level sensors. Connects to SeaLand or other tank monitor to warn when tank
is nearing capacity .
“Full tank” shutdown relay. When tank reaches “full”, relay turns off power to toilet system to
prevent possible tank overfill .
Implosion protection. Heavy-duty tank and reinforcing ribs combine to prevent potential damage
from dockside pumps that may operate at high levels of vacuum .
Thorough tank discharge. Top-mounted diptube design provides most efficient pump-out of effluent.
