2. The VHT inlet must not be located more than 3 feet (0.9 m) to remove entire above the outlet of the toilet. (NOTE: The lower the tank, the unit better the system efficiency.) 3. The VHT must be mounted in a horizontal position. 4. The VHT must not be exposed to temperatures over 120°F (49°C). Do not place near heat sources such as engine manifolds, water heaters, generators, etc. Mounting space must provide for free air flow. Vacuum hose Follow routing 1. OdorSafe Plus Sanitation Hose should be used; it is sized to use SeaLand fittings in the system, minimizing vacuum and fittings instructions leakage. 2. It is important that restrictions in the vacuum hose be kept to a minimum. Where a bend must occur in a hose run, the ra- dius of the bend must not be less than 8.5 inches (216 mm). If a tighter radius is required, use a SeaLand 90° bend kit to assure a clog-free transition. insTallinG VacuuM ToilET 1.

Add freshwater antifreeze to potable water tank. 3. Flush potable water antifreeze and water mixture through toilet and into the waste holding tank. Each installation is different, so amounts may vary. User discretion is required. 4. Empty holding tank. -
Page 12: Deodorants And Special Tissue
DEoDoRanTs anD sPEcial TissuE Your SeaLand toilet system may require the regular addition of a deodorant product to reduce malodors and to help break down holding tank contents. Several factors should be considered in selecting a deodorant product. liquid or Granulated. Liquid products work more quickly by readily going into solution. Granulated powder formulations have the advantage of requiring less storage space and are less likely to leak if the package is inadvertently damaged. Formaldehyde versus non-Formaldehyde. Dometic manufactures both types of deodorants. -
