Restraining Strap Installation (fig . 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 flow of bilge water.
6.3 Install sanitation hose
SeaLand vacuum holding tanks are pre-assembled with 38 mm (1.5 in.) and 16 mm (0.625 in.) ID hose
connection fittings . SeaLand 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.
SeaLand MaxFlex™ hose is recommended for 5/8-in. ID vent hose fitting installation as it provides
high-quality odor-resistance .
Routing Sanitation Hose
• Protect hose when routing through walls or other barriers (fig.
6 A, page 3) .
• Avoid binding corners and sharp bends in hose ( fig. 6 B, page 3) .
• Do not use wire ties to secure hose or pipe. Support flexible 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 (fig .
6 C, page 3) .
Bulkhead Penetrations (fig . 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 flexible 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 fitting(s) (see previous section for hose routing guidelines) . VHT inlet and outlet fittings
swivel to allow connection from virtually any direction (fig .
5 , p . 3) .
2 . Route 5/8 in ./16 mm vent hose from vacuum pump discharge to vent filter or thru-hull vent fitting .
3. Place two hose clamps on hose near each end that attaches to fittings. Use Dometic Hose
Lubricant (fig . 8 , p . 4) or liquid dishwashing soap on fitting and inside ends of hose, then twist
hose onto fitting. Make sure hose end is flush against fitting shoulder.
4 . Tighten hose clamps at ends of sanitation hose with screws positioned as shown (fig . 9 , p . 4) .
Vent hose requires only one hose clamp at each connection .
