 INSTALLATION INSTRUCTIONS

Improper installation, operation or servicing this product will result in equipment damage &
personal injury. This product should be installed & serviced by qualified technical personnel
who have an in-depth knowledge of the construction process and potential hazards of this type
of system.
• All B&B installed fittings are torqued to factory settings. Loosening or tightening these connections will
result in potential leakage or damage voiding warranty consideration.
• All plumbing connections made to this product during installation should be hand tight plus ¼ turn.
DO NOT over-tighten!!
• DO NOT "operate" equipment at power levels other than what is specified on equipment serial tag & data
plate.
• Make sure tank fittings for black water tank flushing (ABS Tank & Rotomolded) are installed per
instructions to avoid potential damage.
• DO NOT install panel with plumbing in a binding condition. Plumbing must have necessary room to move
freely when panel is secured to mounting substrate.
• Double check ALL factory installed swivel fittings to hand tight plus ¼ turn due to potential loosening.
• OEM Manufacturer to provide user instructions clearly advising proper winterizing techniques. Damage to
system due to incorrect winterizing techniques voids all warranty consideration.
• B&B Molders is not responsible for damage caused to other products connected to this system. It is the
O.E.M. Manufacturer's responsibility to ensure plumbing is run to correct locations.
• Proper venting of freshwater holding tank is responsibility of RV manufacturer. (See B&B Power Vent for
safe venting options.) Under sized vents may result in serious damage.
• Special rules apply for any warranty claim or submission. Please contact B&B Molders for further
information.
• Do not use countersink headed screws due to potential cracking. Use only #8 pan headed screws.
• Nautilus System is designed for compartment use only and should not be used for exterior applications
where exposure to exterior elements exists.
• System must be installed in a clean environment at O.E.M. free of dust and debris. Foreign contaminates
have been proven to create leakage conditions.
• Optional: If this product comes equipped with a hot/cold faucet, make sure hot and cold are connected
correctly. All plumbing connections made to this product during installation should be hand tight plus ¼
turn.
Tank Flush
• DO NOT over-tighten swivel fitting to threaded water inlet connection. Over-tightening may result in stress
cracking to plastic threads.
• DO NOT plumb Atmospheric Vacuum Breaker/Check Valve (Vac/Check) in a binding condition that puts
stress on part. Plumbing should be securely fastened to permanent structure.
• B&B strongly recommends installing Vac/Check within 6' – 8' of water inlet due to low pressure conditions.
• Vac/Check must be installed in an easily accessible location to end user.
• Vac/Check assembly must be plumbed in proper direction of flow & orientation.
• Working pressure per ASSE #1001 is 125 psi but NOT LESS THAN 8 psi.
• Spin weld fitting/sprayer must be installed according to Standard Plastic Welding Guidelines.

IMPORTANT: FAILURE TO FOLLOW THESE INSTRUCTIONS FOR INSTALLATION OF OUR PRODUCT WILL
FORFEIT ANY WARRANTY CONSIDERATION.
