CHECK VALVE:
On Evolve air filters, a 3/8” check valve is part of the
air draw assembly which includes tubing and a screen. Insert the tubing
into the elbow on the control valve
(see diagram at right)
. As the
piston travels through various positions, ports are opened momentarily
(2-3 seconds) which may allow a small amount of water to discharge
through this assembly. The check valve prevents this flow of water.
NOTE:
Under certain conditions (finished basement, utility room, etc.),
it may be advisable to run this air draw assembly to a drain.

DISINFECTION OF SYSTEM:
In situations where additional disinfection is
needed, due to high levels of iron or sulfur bacteria, this may be accomplished
with a small chlorine feeder
(see diagram at right)
. It can be used in
conjunction with air systems and is used to control bacterial growth within the
filter vessel itself. It is not used to control bacteria downstream of the filter nor for
disinfection of the water itself. Chlorine disinfection is not used with some medias
such as Birm. Please consult distributor or factory for more details.
This tank operates much the same way a brine tank does with a water softener.
A small amount of water is added to the tank just prior to regeneration, which
comes into contact with the chlorine pellets, dissolves them and is then drawn
into the filter to disinfect the system periodically and then safely rinsed away. We
recommend the use of pellets manufactured by Better Water Industries, available
through the manufacturer or your local distributor.
To Dealer:
CAUTION:
On certain Evolve air models, the Backwash Air
cycle is not available when using the chlorine
feeder tank. Drain line must be of rigid materials and
affixed securely to floor, wall or ceiling.
See Drain Line instructions.
This tank has many intended uses. If chlorine is being used, add only two or
three pellets (two or three grams) of chlorine at a time. We recommend Better
Water Industries chlorine pellets. Do not overfill container. Use rubber gloves
when handling pellets. Always read safety precautions of chemical container
before adding to tank.
If chlorine is being used, never add or mix any chemical in chlorine tank other
than chlorine. Always read safety precautions on container before adding any
chemical to this tank. Only use in well ventilated area. Chlorine fumes can
be corrosive and harmful. Inhalation of chlorine gas can be deadly. Use drip
pan underneath tank in case of corrosion or leaking of tank. Always install
an overflow line to the chlorine tank and run to an appropriate drain. Do not
connect drain from filter to this tank. Drains should remain separate.
