SANITATION SYSTEM COMPONENTS (cont’d)
Vacuum Toilet: The 3600 series vacuum toilet with Flush
and Forget
®
technology operates in a way different from
other marine toilets. Vacuum systems use a small amount
of water (a little more than a pint or .5 liter) per ush in
addition to a simple vacuum. The toilet is connected to a
pressurized freshwater system. Fresh water is the key to an
odor-free bathroom compartment. VacuFlush toilets are
equipped with an integral vacuum breaker which prevents
the possible contamination of the freshwater supply.
Flush/Add Water Switches: Wall-mounted push-button
switches provide electronic operation of ushing and adding
water to the toilet bowl. Models include two-light vacuum
status panel indicating the toilet is “OK to Flush” or “Do Not
Flush”. Models vary.
Vacuum Generator: VacuFlush vacuum generators
combine the vacuum tank and vacuum pump in one unit.
It greatly reduces installation time and eliminates the hose
run between the tank and pump. Our vacuum generators
are available in standard or low-prole congurations,
depending on installation requirements.
Vacuum Tank: The vacuum tank stores vacuum energy.
System vacuum level is monitored by a vacuum switch
located on the vacuum tank. When this switch senses
a drop in vacuum in the system, it automatically signals
the pump to energize and bring the vacuum to operating
level. This process is normally completed in less than one
minute.
Vacuum Pump: The vacuum pump is an electric,
straight-through bellows type. It is manufactured of long-
lasting polypropylene and draws only 4 to 6 amps of current
at 12 VDC. This unique pump design is both an efcient air
and liquid pump that handles solids without a problem. It
has two duckbill valves on each side of the pump chamber
to maintain vacuum and prevent backow of waste.
TankWatch
®
Level Indicator (optional): The TankWatch
unit utilizes micro-oat switches which activate an indicator
panel. The inspection cap in the holding tank contains the
micro-oat switch units. The adjustable probe assemblies
are exible polybutylene tubing and are designed to ex
when tank contents move.
Holding Tanks (optional): SeaLand holding tanks are
made of super-strong, 3/8” (10mm) thick polyethylene
— 50% thicker than most other holding tanks. Each unit
has a solid, one-piece construction with no seams for un-
matched durability. A deodorant additive is required to keep
the holding tank odor-free. See Deodorants and Special
Tissue section for further information.
