INSTALLATION OF COMPONENTS

1. Installing the Toilet

For VacuFlush and EcoVac toilet mounting, follow the instructions in the VacuFlush Installation Guide.

2. Routing and Installing Hose

Before attaching the vacuum hose to a fitting, place two hose clamps over hose end. (All connections must be double clamped.) Apply liquid dishwashing soap to out- side of hose connector and inside hose. Twist hose clockwise as it is pushed onto adapter (see Figure 2). Hose end should be flush against the fitting shoulder when properly installed (see Figure 3). Twist the hose counter-clockwise before placing it onto the fitting. This will ease installation. All joints should be double clamped with high quality stainless steel clamps. Make sure clamp mechanisms are 180° from each other when tight (see Figure 3). Failure to follow these procedures will result in vacuum leaks.

3. Connecting the Toilet Water Supply Lines

The water supply inlet must connect to an adapter which will adapt to the 1/2-inch MPT connection on the toilet water valve. (This adapter can be found through a local supplier or through Dometic.) The water supply must provide a minimum flow of two (2) gallons per minute (7.6 liters per minute).

4. Mounting the Vacuum Holding Tank

The Vacuum Holding Tank (VHT) can be located in any accessible space as long as the 1-1/2 inch hose is not longer than 20 feet (6.1 m) and its inlet is not higher than 3 feet (.9 m) from the toilet outlet. The VHT must be mounted horizontally.

Mounting spindles are provided for securing the VHT in areas that prevent access to the rear mounting feet on the VHT.

Position the VHT in the space intended. If using mount- ing spindles, mark holes at rear of tank. After holes are marked, remove VHT and secure (3) of the spindles pro- vided to the mounting surface using (3) #12 x 1-1/2 inch long pan head wood screws. Slide the VHT back so mounting spindles fit into slots on tank (see Figure 4). Secure the tank by using the (3) remaining spindles and

(3)#12 x 1-1/2 inch long pan head wood screws on re- maining tank mounts.

If not using the mounting spindles, secure the VHT with

(8)#12 x 1-1/2 inch long pan head wood screws and (8) flat washers on all (8) tank mounts. NOTE: The VHT must be secured by at least (6) of the (8) mounting feet.

Once the VHT is in place, connect hose from toilet. (NOTE: Hose insert elbow fittings can be removed from VHT.)

5. Making Electrical Connections

See the “Wiring Diagram” section of this manual.

6. Completing the Installation

Complete installation of discharge hose from outlet of VHT to a discharge deck fitting or overboard discharge pump.

The tank is designed for easy installation and maintenance, featuring a compact size that fits smoothly into the limited spaces typical in marine vessels.

Another notable characteristic of the SeaLand Vacuum Holding Tank is its innovative level monitoring technology. This feature enables boat owners to track the waste level inside the tank accurately, which is crucial for ensuring compliance with marine sanitation regulations. The monitoring system alerts users when the tank reaches its capacity, prompting timely disposal and preventing overflow situations.

Moreover, SeaLand focuses on user-friendliness, ensuring that its vacuum holding tank is compatible with a variety of marine sanitation systems. The installation process is straightforward, and the tank can be integrated with existing components without requiring extensive modifications. This flexibility makes it a preferred choice for boat builders and owners looking for an efficient waste management solution.

In summary, the SeaLand Vacuum Holding Tank is a state-of-the-art waste containment system for marine applications. Its vacuum technology, durable construction, level monitoring capabilities, and ease of installation set it apart from traditional holding tanks, making it an ideal choice for any vessel seeking effective waste management solutions. Whether for recreational or commercial use, this tank ensures that boating remains a clean and enjoyable experience.
