VACUUM HOLDING TANK

SYSTEM

Vacuum Toilet: The EcoVac toilet operates in a way different from other marine toilets. EcoVac systems use a small amount of water (a little more than a pint) per flush 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 compart- ment. EcoVac toilets are equipped with an integral vacuum breaker which prevents the possible contamina- tion of the potable water supply.

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. In a properly operating system, the stored vacuum will leak down between flushes, causing the vacuum pump to run for a short period.

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 efficient air and liquid pump, and handles solids without a problem. It has two duckbill valves on each side of the pump chamber.

Vacuum Generator: The vacuum generator combines the vacuum tank and vacuum pump in one unit. It greatly reduces installation time and eliminates the hose run between the tank and pump. Its compact size makes it especially well-suited to smaller crafts.

Vacuum Holding Tank: The vacuum holding tank combines the vacuum tank, vacuum pump and holding tank. Refer to the Vacuum Holding Tank Owner’s Manual (Part No. 343026) for installation and trouble- shooting information.
