HTS Benefits

Superior Durability: SeaLand ® holding tank systems (HTS) are molded from linear low density polyethylene (LLDP) resin.

Polyethylene is best-suited for holding tank construction because of its resistance to corrosion and odor permeation, and it will last longer than the life of a typical fiberglass hull.

Leak-Proof Design: All hose connections in SeaLand holding tanks are on the top of the tank, eliminating possibility of leakage due to a faulty connection below the liquid level of the tank contents. Our unique diptube design reduces the risk of plugging while keeping the residual contents in the tank to a minimum.

Typical

Discharge Outlet

SeaLand Diptube

Discharge Outlet amount of residual effluent amount of residual effluent

ISO/USCG Compliant: SeaLand HTS models are fully compliant with the ISO 8099:2000(E) standard and applicable requirements of the United States Coast Guard for pleasure craft installation.

Odor-Free Design: SeaLand tanks have extra-heavy wall thickness to prevent odor permeation. Holding tank systems can be fitted with a SaniGard™ in-line vent filter that stops unpleasant odors from escaping through the holding tank vent.

Implosion Protection: SeaLand holding tanks are equipped with a TankSaver™ vacuum relief valve which prevents damage from dockside pumps that operate at very high levels of vacuum. The TankSaver valve opens automatically under vacuum conditions, but remains sealed regardless of shock-loading or vibration.

Multiple Tank Outlets: Most HTS models are equipped with two discharge outlets. One is for connection to a deck-mounted discharge fitting and one is for connection to an overboard discharge pump.

HTS Components: Every HTS is built with high-quality SeaLand sanitation system components. See page 6 for details.

Installation

CHOOSING A LOCATION FOR THE HTS

As a general rule, the HTS should be positioned as low in the hull as possible with all interconnecting hoses or pipes sloped to permit gravity drainage and prevent potential hose odor permeation.

The holding tank must not be exposed to temperatures above 120°F (45°C). Do not place near heat sources such as engine manifolds, water heaters, generators, etc.

Be certain to estimate holding tank weight when filled (typical effluent weighs about 9 lbs. per 1 gallon or 1.08 Kg per liter). Make certain to allow for total filled weight when selecting materials for mounting the tank. Also consider impact of full tank on vessel trim.

Integrated mounting feet in holding tank simplify installation.

Preparing a Mounting Surface

1. Mount tank to surface that supports the entire area of the tank.

2. If required, fabricate mounting surface and toe blocks from

13 mm or 19 mm (1/2-inch or 3/4-inch) plywood.

3. Do not mount tank on projections such as screw or bolt heads, which could puncture the tank.

4. Do not allow holding tank to block free flow of bilge water.

Mounting surface can be made from plywood and securing straps.

AVOIDING HOSE ODOR PERMEATION

• Hose failure due to odor permeation almost always occurs in hose runs which retain sewage when the system is not in use.

• Eliminate all unnecessary runs which retain trapped liquids, if possible.

• Where possible, use rigid PVC pipe in sections that cannot be arranged to drain.

• Simplify hose layout by removing unnecessary valves.

[For specific installations, some regulations and standards may require the installation of a vented loop

(anti-siphon valve), one-way valve or seacock in sewage discharge piping.]

PLUMBING CONNECTIONS AND HOSE LAYOUTS

When connecting flexible hose to plastic fittings, use Dometic

Hose Lubricant or silicone grease on end of fitting and inside hose end to make connection easier.

Do not use any other lubricants, sealants or adhesives when connecting sanitation hoses and plastic fittings.

Do not restrict the ability to pull the hose or pipe.

YES YES

TROUGH SUPPORT

EXCELLENT

Avoid binding corners and sharp bends.

Do not use wire ties to secure the hose or pipe.

Support flexible hose every 12 inches

(.3 m), and support rigid pipe every 5 feet

(1.5 m).

When creating new holes, avoid reinforcement stringers and tabs.

IF SEALAND HTS-BASIC TANK FITTINGS ARE NOT ASSEMBLED TO TANK, FOLLOW THESE STEPS.

3-inch cap – inspection port

1. Place cap into 3-inch (76 mm) threaded hole (fig. 1 ) and tighten until hand-tight.

2. Using spanner wrench or large channel locks, tighten cap until very little or no black seal is visible above inlet port (fig. 2 ).

3. To remove cap for tank inspection, use spanner wrench or large channel locks.

Inlet and discharge elbow fittings

1. Apply threaded plastic pipe sealant around threads of elbow (fig. 3 ).

2. Tighten elbow into desired fitting on tank (fig. 4 ).

3. To properly position elbow to receive sanitation hose, turn elbow only in clockwise direction (fig. 4 ). (Turning the elbow in opposite direction may loosen connection and cause leakage.)

4. Make sure to connect waste discharge hose(s) to fitting(s) marked as

“Waste Only.”

5. When connecting sanitation hose to plastic elbows, use silicone grease on end of fitting and inside hose end to help make connection easier and leakproof. Be sure to use two hose clamps to secure each connection.

CLAMP CONNECTIONS FOR FLEXIBLE HOSE AND

FITTINGS

Dometic recommends that each hose connection be secured with two hose clamps to prevent any leaks.

Position clamp screws 180° apart from each other and tighten clamps.

SOLVENT BONDING FOR RIGID PIPE AND FITTINGS

1

2

1. Use PVC cleaner on both bonding surfaces.

2. Use PVC cement (must contain tetrahydrofuran) on both bonding surfaces.

3. Connect parts using a twist and hold motion until the cement is set.

4. Let the joint cure for at least four hours or according to instructions on PVC cement container. (Cold temperatures require longer cure times.)

3

Vent Line and Filter Installation

• Holding tank vent lines must be free of low points which can trap liquid and prevent the free flow of gases from or air into the holding tanks.

• Do not use non-reinforced hose for vent lines. Over time, it will tend to kink and effectively block the vent.

• A holding tank vent filter will absorb heavier-than-air gases associated with sewage and eliminate a source of malodor from the exterior of the boat. See vent filter details in this manual (page 6).

When installing vent filters that are not mounted directly on an HTS unit:

• Avoid areas near excessive heat sources such as engine manifolds or lights.

• Do not install the filter below top of holding tank.

• The filter can be mounted in any position. Installations near the through-hull vent reduce the chance of filter damage from overfilling of the holding tank.

Service access

Because SeaLand holding tanks may require minimal service in normal operation, the tank must be installed so that there is easy access to the tank inspection port, discharge pump and vent filter (if installed).

An in-line maintenance valve must be installed in any piping runs which retain liquid and are connected to components that may require periodic servicing (such as discharge pumps).

Cleaning

A small amount of water remains in all marine holding tanks. It is good practice to rinse the tank after the contents have been discharged. This can be accomplished by adding water to the toilet bowl. Add 8 ounces (237 ml) of SeaLand ® Holding Tank

Deodorant to the bowl. Flush the entire contents into the holding tank and continue flushing until the discharge from the holding tank is clear.

Do not use chlorine-based cleaners, caustic cleaners or chemicals, such as drain-opening products, as they may damage the system’s seals and hose.

Winterizing

If using the HTS with SeaLand’s VacuFlush ® components, refer to VacuFlush toilet owner’s manual for winterization instructions.

If using antifreeze to winterize the HTS, use only propylene glycol freshwater antifreeze that does not contain alcohol. Antifreeze that contains alcohol will result in damage to your sanitation system.

1. Pump out holding tank.

2. Thoroughly flush the system with fresh water before adding propylene glycol freshwater antifreeze to the HTS.

HTS Components

DTM04 Level Monitor and Micro-Float Switches*

I n c l u d e s f o u r t a n k levels – Empty, Low, Mid and Full. Micro-float switches are installed in holding tank. No electrical components contact waste or water. Operates on 12 or 24-volt DC. Uses only .008 amps at 12 V

DC. Micro-float switches are installed either as a unit (with a 3-inch cap) or as separate indicators.

VacuFlush

Shutdown Relay*

To prevent overfilling a holding tank, a shutdown relay is supplied with HTS-

VG models. When the tank reaches "Full", the relay shuts off the vacuum generator, preventing further flushing of the toilet.

Combined

Float Switches

Separate

Float Switches

VacuFlush ® Vacuum Generators*

On HTS-VG models, VacuFlush vacuum generators combine the vacuum tank and vacuum pump in one unit. All models eliminate hose runs between the vacuum tank and pump of previous VacuFlush systems. HTS vacuum generators feature high-performance vacuum pumps, offering quieter operation and faster vacuum generation than previous models.

Other HTS Features

TankSaver™ Vacuum Relief Valve

Prevents damage due to tank implosion from dockside pumps that generate very high vacuum.

TankSaver valve opens automatically under vacuum, but remains sealed regardless of shockloading or vibrations.

SaniGard™ Holding Tank Vent Filter*

With odor-removing filter media, the vent filter stops odors from escaping the holding tank vent. Keeps boats smelling clean and pleasant. Each cartridge is good for an entire season and is easily replaced.

OdorSafe ® Plus Sanitation Hose

OdorSafe Plus hose provides the best odor barrier of any marine hose available. It delivers up to 19 times greater resistance to sulfurous malodors than other “noodor” marine hoses. On

HTS models, it's used for all 1.5-inch (38mm) hose connections. It's also best for connecting the discharge pump to the through-hull and deck waste fittings.

SaniPump™ Overboard

Discharge Pump*

Runs dry without harm. Draws

6 amps at 12 VDC. Delivers flow rate of 3.9 gallons per minute (14.7 liters per minute). Connects to through-hull fitting. Check Marine

Sanitation Regulations for information on areas where discharge is allowed.

* Not available on all HTS models.

Diptube Discharge

Our diptube discharge design allows for removal of waste from the top of the holding tank rather than near the bottom of the tank. This feature greatly reduces the opportunities for stagnant sewage to sit in tank discharge lines – a main cause of odor permeation and hose failure.
