The control valve, fitting assemblies and bypass valve are
designed to accommodate minor plumbing misalignments
but are not designed to support the weight of a system or
the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or
spray silicone anywhere. A silicone lubricant may be used
on black o-rings but is not necessary. Avoid any type of
lubricants, including silicone, on the clear lip seals.
The nuts and caps are designed to be unscrewed or
tightened by hand or with the special plastic wrench (V3193).
If necessary, pliers can be used to unscrew the nut or cap.
Do not use a pipe wrench to tighten or loosen nuts or caps.
Do not place a screw driver in the slots on caps and/or tap
with a hammer.
Do not use pipe dope or other sealants on threads. Use
Teflon tape on the threaded inlet, outlet and drain fittings.
Teflon tape is not necessary on the nut connection or caps
because of o-rings seals.
After completing any valve maintenance involving the drive
assembly or the drive cap assembly and pistons, unplug
power source jack from the printed circuit board (black wire)
and plug back in or press and hold

buttons
for 3 seconds. This resets the electronics and establishes the
service piston position. The display should flash the software
version and then reset the valve to the service position.
Solder joints near the drain must be done prior to connecting
the drain line flow control fitting. Leave at least 6” between
the drain line control fitting and solder joints when soldering
pipes that are connected on the drain line control fitting.
Failure to do this could cause interior damage to the drain
line flow control fitting.
When assembling the installation fitting package (inlet and
outlet), connect the fitting to the plumbing system first and
then attach the nut, split ring and o-ring. Heat from soldering
or solvent cements may damage the nut, split ring or o-ring.
Solder joints should be cool and solvent cements should
be set before installing the nut, split ring and o-ring. Avoid
getting primer and solvent cement on any part of the o-ring,
split rings, bypass valve or control valve.
If the building’s plumbing is metal (e.g. copper) and the
building’s electrical system is grounded to the plumbing,
install a copper grounding strap from the filter inlet pipe to
the filter outlet pipe.
This water filter is not to be used for treating water that is
microbiologically unsafe or of unknown quality without
adequate disinfection before or after treatment.
The Enhanced Oxidation Generator (EOG) is an ozone
generator for use with LXKATAIRO3 models ONLY .
Ozone is NOT recommended for filter models using
Carbon, Catalytic Carbon or Birm.
Do
NOT use the ozone generator on chlorinated water
supplies - chlorate may be formed with the presence
of residual chlorine. The chlorate ion is one of the
contaminants being considered for regulation in drinking
water under the disinfection by-product rule.
GENERAL INSTALLATION
AND SERVICE WARNINGS
PRE-INSTALLATION
REVIEW
WATER PRESSURE: A minimum of 20 psi water pressure
is required for backwash. Maximum 100 psi. CAUTION: the
filter cannot be subject to a vacuum due to loss of pressure
(such as a water main break or submersible well pump check
valve failure) as this may cause the filter tank to implode
and could cause leakage. Provide a vacuum breaker in the
installation if the possibility of a vacuum could occur.
WATER TEMPERATURE: The range of water temperature
is 40°F to 100°F. DO NOT install any water filter with less
than 10 feet of piping between its outlet and the inlet of a
water heater. CAUTION: the use of a thermal expansion tank
might be required to protect the filter in the event of a hot
water heater backup. Refer to installation diagrams.
AMBIENT TEMPERATURE:
DO NOT locate filter where it or
its connections (including the drain line) will ever be subject
to room temperatures under 33°F.
ELECTRICITY: An uninterrupted 120 volt 60Hz source
is required.
Make sure electrical source is not on a timer
or switch.
All electrical connections must be connected
according to local codes. The plug-in power adapter is for
dry locations only. Surge protection is recommended with all
electrical connections.
Control Valve (all models) plug-in power adapter
rating...
Input: 100-120 VAC, 50/60 Hz, 0.35 A
Output: 15 VDC, 0.5 A
Enhanced Oxygen Generator (LXKATAIRO3 models
only) plug-in power adapter rating...
Input: 100-240 VAC, 50/60 Hz, 0.5 A
Output: 12 VDC, 1.5 A
DRAIN: All plumbing should be done in accordance with
local plumbing codes. The distance between the drain
and the water filter should be as short as possible. Avoid
overhead drain lines if possible to prevent backpressure on
the system. Refer to installation diagrams for drain line pipe
size recommendation.
FILTERING: It is recommended that the filter be installed
to treat both the hot and cold water supply. Outside faucets
should be left on untreated water.
BYPASS: A bypass valve (included with all models) should
be installed so that water will be available if it should be
necessary to shut off the pressure in order to service the filter.
