Installation
If you decide to install the Nature
2®
Purifier yourself, follow these
instructions.
Under normal pump and filter pressure conditions for vinyl liner
pool systems, the flow rate to the inlet side of the purifier is
95-303 L/min (80 gpm) which will allow proper flow through the
cartridge.
IMPORTANT If your pump system is designed to produce
flow rates greater than 303 L/min (80 gpm), ask your
dealer about
installing in a bypass
configuration.
If the Nature
2
Purifier is to be installed below the water level of
the pool, precautions must be taken to prevent the pool from
draining during installation and during cartridge change. Valves
should be installed to isolate the system for these situations.
Equipment needed:
• A set of
shut-off valves
or rubber winterizing line-plugs
to use during cartridge installation or replacement to
prevent draining (used in step 5).
• A filter
connector hose
of the same diameter as the
other hoses on your pool equipment (used in step 7).

Install the Vessel
Refer to the diagram below for part references.
1.
Decide where
to install the Nature
2
vessel. It should be
installed:
• On a concrete slab to support the weight of the vessel.
• After the filter on the main return to the pool.
• Before or after the heater (downstream of solar heating
systems)
.
• Before any chemical dispenser or the discharge of any off-
line chemical dispenser.
IMPORTANT
Install a check valve before chlorinators to
isolate the
Nature
2
purifier from possible
backflow of highly chlorinated water
.
2.
Wrap Teflon
®
*
tape
(supplied in the parts bag) around the
threaded end of the hose adapters as follows:
• Hold adapter with the threaded end towards you.
• Wrap the tape clockwise until you have completed three or
four wraps, overlapping about half of the tape already on
the threads.
NOTE
Hose adaptors provided are designed for above
ground pool installations. If you are installing on
an inground pool, it is recommended that you
purchase the appropriate fitting for your application.
Ask your dealer for more information.
3.
Hand-tighten
both hose adapters into the base of the Nature
2
purifier. Then, with a wrench, tighten not more than on-half
turn more. The purifier is now ready to be installed.
4.
Run the pump
with a clean filter and under normal operating
conditions. It is important to start with a clean filter. Fill in the
pressure reading found on the pressure gauge attached to
the filter.
