INSTALLATION GUIDE
LOCATION
When locating your new Nature's Head be sure to allow enough room for the lid to open fully.
Also, you must be sure the Bowl has enough room to tilt rearward to allow for its removal and for
the removal of the liquid tank. Remember that you have to allow enough room for the hose connection
and for the handle for the composting agitator. Both of these can be re-located to either side of the
unit for ease of installation.
MOUNTING
The head will be secured to the floor of your boat, truck,
or cabin by the two L-brackets which may be positioned to the inside or outside of the base of the
unit as you desire. Mounting screws (or bolts) are not included as various options for mounting are possible.
If you choose to mount your unit with the L brackets facing inward in the recesses provided in the base,
be sure and use counter-sunk screws or bolts. The holes in the brackets are for a 1/4 inch bolts or screws.
Do not over tighten the hold down knobs - as you will damage the threads in the base!
VENTING
The unit must be vented to the outside of your cabin whether it is a boat, RV, truck, or vacation property.
This helps keep your bathroom smelling fresh, and allows for proper growth of beneficial bacteria which
facilitates the composting process. Solar vents, mushroom vents, or clamshell vents
(which are not provided with your head) are commonly used for venting to the exterior.
The unit may be vented horizontally or vertically. Hose adapters which connect directly to
your head and the outside vent are provided. We will also offer a trim ring to help in installations
where a pre-existing vent hole is bigger than the provided connector. The Venting hose provided
with the unit will attach directly to the adapters. Clamping is not necessary on the connection for the Head,
and normally not necessary on the exterior connecter. On an overhead connection, you may find it
necessary to clamp this end depending on the amount support you provide for the vent hose. If the hose is
supported properly, you will probably not need a clamp. Remember the vent hose must go on the housing
that has the fan inside of it. The unit is designed to pull fresh air through the Head and ventilate it outside.
If you disassemble the fan housing, always remember to check that the fan is blowing out of the vent
before attaching the vent hose.
POWER CONNECTION
A simple 12 volt computer style fan drawing less than 1 amp is the only power required for this unit.
The power hookup, a single pin attachment with a wire length of 6 feet, is also included.
It may be necessary to extend the length of the connecting wire. The fan may also be powered by
a 110 volt source with an appropriate power adapter that reduces the power to 12 volts! These power
adapters are available through many electronic supply houses and will be available through Nature's Head Inc.
As with all electrical connections, be sure your Head is on a fused circuit. (The fuse should be no less than
2 amps and no more than 5 amps.) This unit can also be installed in a completely powerless installation by
using a solar vent on the roof or cabin top and attaching the vent hose underneath. Be sure and use a solar
vent with battery back-up so your Head will vent continuously. The fan can be left in the unit if you choose this
option.
INSTALLATION TIPS
If installation of the ventilating hose is better suited to placement on one side of the unit than the other,
the fan/filter flange is interchangeable with the filter-only flange. This is accomplished by swapping sides
with the components and their respective housings. The agitator handle must be attached to the pre-threaded
agitator before use. In the event that the handle must be moved to the opposite site of the base, the agitator
must be manually removed, reversed, and replaced. The extended nut must be re-attached before connecting
the handle. It is recommended that you use a wrench to hold the extended nut while you tighten the nut to the
agitator and then the handle to the nut. Both should be reasonably tight so that they do not become loose when
the unit is in service. (While not required - you could use a thread locking compound on these parts if you have it.)
