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 efuent
to prevent possible hose permeation of odor. Heavy-wall polyethylene tank prevents odor
permeation and corrosion.
Leakproof performance. Vacuum holding tank ttings 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 ushes between pump-outs than standard electric marine toilet systems.
Energy efficient. Draws only 3 amps per ush (12V DC).
“3/4” and “full” tank level sensors. Connects to Dometic 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 overll.
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 efcient pump-out of efuent.

5.3 Dimensions (g. 2, page 2)
6 Installation
6.1 Choose a location for the VHT
The VHT 5200 series tank is specially shaped to install against the hull just outboard of a boat’s head
compartment. Follow these criteria when determining a location:
1. The inlet tting (g. 1A, p. 2) must be no more than 20 ft. (6.1 m) horizontally from, and no more
than 5 ft. (1.5 m) above, the toilet discharge tting. (The closer the VHT is located to the toilet, the
better the system efciency).
2. The VHT must be installed vertically.
3. Install VHT where access to discharge ball valve is available or can be created (with removable
access panel or door).
4. Do not expose VHT to temperatures above 120° F (49° C). Do not place VHT near heat sources
such as engine manifolds, water heaters, generators, etc. Allow free air ow around VHT.
6.2 Install VHT on mounting surface
Bottom mounting surface must support the entire bottom of the tank. If a mounting surface needs
to be fabricated, use marine grade plywood at least 0.5 in. / 13 mm thick.
Note
Fasteners (lag bolts, screws, washers, etc.) and restraining straps are not supplied with
vacuum holding tank.
SailVac Vacuum Holding Tank Specifications

8
Restraining Strap Installation (g. 4, page 3)
With restraining straps of 31 mm (1.25 in.) maximum width fastened to hull brace or bulkhead, wrap
straps around front of tank to both sides of tank, positioning the straps within the channels on the
tank. Tighten and secure straps to keep VHT from moving.
Caution!
Do not install tank on projections, such as fastener heads, which could puncture the tank.
Do not allow holding tank to block free ow of bilge water.
6.3 Install sanitation hose
Dometic vacuum holding tanks are pre-assembled with 38 mm (1.5 in.) and 16 mm (0.625 in.) ID hose
connection ttings. Dometic OdorSafe®Plus sanitation hose provides the best protection against hose
odor permeation for toilet and holding tank discharge lines, and is available in 38 mm (1.5 in.) ID only.
Dometic MaxFlex™ hose is recommended for 5/8-in. ID vent hose tting installation as it provides
high-quality odor-resistance.
Routing Sanitation Hose
• Protect hose when routing through walls or other barriers (g. 6A, page 3).
• Avoid binding corners and sharp bends in hose ( g. 6B, page 3).
• Do not use wire ties to secure hose or pipe. Support exible hose every 0.3 m (12 inches) and
support rigid pipe every 1.5 m (5 feet). Where possible use a support trough under the hose or
pipe (g. 6C, page 3).
Bulkhead Penetrations (g. 7, page 4)
Check each side of a bulkhead to ensure that there will be no cutting into:
• fuel or water tanks
• wiring or pipes
• reinforcement stringers (4) that support the hull
When creating new holes, avoid tabs (1) and stringers (4) that hold bulkheads or partitions in place.
Provide additional reinforcement so that structural integrity is not compromised.
• avoid (2)
• possible (3)
Hose and Heat Sources
The operating temperature of exible hose prohibits exposure to sources of high or direct heat, such
as light bulbs or engine manifolds. If any part of the hose system must be run close to a heat source,
use rigid pipe instead of hose.
6.4 Make connections
1. Route 1.5 in./38 mm ID sanitation hose from toilet to VHT inlet, and from VHT outlet to the boat’s
discharge tting(s) (see previous section for hose routing guidelines). VHT inlet and outlet ttings
swivel to allow connection from virtually any direction (g. 5, p. 3).
2. Route 5/8 in./16 mm vent hose from vacuum pump discharge to vent lter or thru-hull vent tting.
3. Place two hose clamps on hose near each end that attaches to ttings. Use Dometic Hose
Lubricant (g. 8, p. 4) or liquid dishwashing soap on tting and inside ends of hose, then twist
hose onto tting. Make sure hose end is ush against tting shoulder.
4. Tighten hose clamps at ends of sanitation hose with screws positioned as shown (g. 9, p. 4).
Vent hose requires only one hose clamp at each connection.
Installation SailVac Vacuum Holding Tank

SailVac Vacuum Holding Tank Installation
5. With electrical power off, make electrical connections according to the wiring schematic shown
on the parts list provided with this unit. Electrical installation must follow ABYC standards and
should be performed by qualied personnel only.
Caution!
Failure to follow the procedures above may result in vacuum leaks or inefcient ushing.
Caution – Flooding Hazard!
If the toilet, holding tank or any components are connected to any through-hull ttings,
properly installed seacocks must be installed in all piping connected to the through-hull
ttings. Seacocks must be easily accessible to all users of the system. All valves must be
full-bore valves and of marine (corrosion resistant) quality. Screw-to-close gate valves are
not recommended. Failure to do so can result in ooding, which can cause the loss of life
and property.
Caution – Flooding Hazard!
Some marine practices and/or standards require the installation of a properly positioned
ventilated (vented) loop in the discharge piping to prevent back-siphonage of seawater
into the holding tank. It is up to the system installer and boat owner to select appropriate
means of preventing backow into the holding tank.
7 Operation
7.1 System start-up
1. Fill freshwater tank, then turn on inlet water supply to VacuFlush toilet.
2. Turn on electrical power to vacuum holding tank (VHT).
3. VHT unit may take up to three minutes to initially charge vacuum level and recharge between
ushes.
7.2 Normal operation
VACUUM FLUSHING ACTION
Every time the VacuFlush toilet is ushed, the VHT unit pulls wastewater from the toilet to the holding
tank. The vacuum pump then runs until the proper vacuum level is achieved for the next ush.
Follow ushing instructions in VacuFlush toilet operation manual.
“3/4” and “FULL” TANK PROBES
When the holding tank contents activate the “3/4” tank probe, a signal is sent to a yellow warning
light on the Dometic tank monitor panel (optional). When the tank reaches “full”, a signal is sent
to the red light on the panel, and to a shutdown relay which turns off electrical power to the toilet
system. This prevents the VacuFlush toilet from ushing and overlling the VHT. The VHT must be
emptied before electrical power is restored for normal VacuFlush toilet operation.
7.3 Holding tank pump-out operation
To assure thorough discharge of vacuum holding tank, follow these steps:
1. Turn off electrical power to VHT at circuit breaker and water supply to VacuFlush toilet.
This prevents vacuum pump from starting during pump-out operation.
2. For foot-pedal VacuFlush toilets with built-in pedal lock, follow instruction in toilet operation manual
to keep ush ball in toilet open for holding tank pump-out operation. For electronic VacuFlush
toilets, follow Service Mode instructions for keeping the ush ball open. For all other VacuFlush
toilets, make sure ush ball stays open to allow air into VHT unit during pump-out operation.

10
3. Open discharge ball valve on top of VHT. Pump out holding tank through dockside or
overboard discharge tting.
4. After pump-out, close the discharge valve on top of the VHT, close ush ball in toilet and
resume normal VacuFlush toilet operation.
Caution!
Boat operator must know local sewage discharge regulations.
8 Cleaning and winterizing
8.1 Cleaning
A small amount of water remains in vacuum holding tank at all times, so it is good practice to rinse the
VHT completely after contents have been discharged.
1. After initial pump-out, add holding tank deodorant or cleaner to toilet bowl, and ush with water.
2. Continue ushing and pumping out tank until holding tank discharge is clear.
8.2 Winterizing
Use only propylene glycol freshwater antifreeze to winterize the holding tank. Make sure the
antifreeze does not contain alcohol.
1. Pump out the holding tank.
2. Add propylene glycol freshwater antifreeze to the holding tank.
Caution!
Never use ethylene glycol automotive antifreeze in freshwater systems.
