H 2 ZERO INTRODUCTION / INSTRUCTIONS BEFORE USING

Introduction
The HALO residential H2 ZERO®systems provide protection
from hardness related to scale formation throughout the
plumbing system. The H2 ZERO®system can be installed at
the point of entry to treat your entire home. These systems are
designed to treat the domestic water used in a single family
dwelling. For higher volume applications please contact your
HALO representative.
H2 ZERO®prevents scale by transforming the normal dissolved
hardness minerals into undissolved crystal microparticles.
These crystals stay suspended in the water and have a reduced
ability to react and attach to surfaces. Therefore, the problem
of internal buildup of scale in pipes, water heaters and plumbing
xtures is greatly reduced.
Unlike softened water, H2 ZERO®treated water maintains the
benecial essential mineral content of your water.
Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use information can result
in death, serious personal injury, property damage, or damage to
the equipment.
Keep this Manual for future reference.
The HALO H2 ZERO® system should be installed ONLY by a
licensed contractor.
FAILURE TO COMPLY WITH PROPER INSTALLATION AND
MAINTENANCE INSTRUCTIONS COULD RESULT IN PRODUCT
FAILURE WHICH CAN CAUSE PROPERTY DAMAGE,
PERSONAL INJURY AND/OR DEATH. HALO Water Systems, LLC
is not responsible for damages resulting from improper installation
and/or maintenance. Local building or plumbing codes may require
modications to the information provided. You are required to consult
the local building and plumbing codes prior to installation. If this
information is not consistent with local building or plumbing codes,

Refer to the enclosed for operating parameters to ensure proper use
with your water supply.
• Use only lead-free solder and ux for sweat-solder connections,
as required by state, province and federal codes.
• Handle all components of the system with care. Do not drop,
drag or turn components upside down.
• Be sure the oor under the system is clean, level and strong
enough to support the unit.
• Install the system in a protected area.
• Do not attempt to treat water over 100°F with the system.
• Always connect the system to the main water supply pipe before
the water heater.
• Do not expose the system to freezing temperatures. Water
freezing in the system causes equipment damage.

Equipment Specications
HALO Water Systems, H2 ZERO®systems are completely
loaded with media and ready to use. ZERO drain
necessary, ZERO maintenance & ZERO electricity required
H2 ZERO®media needs to be protected from excess levels
of certain metals that can easily coat the active surface,
reducing its effectiveness over time. If the water supply is
from a municipal supply or a private well, conrm that the
levels of iron (Fe) and manganese (Mn) are less than 0.3
mg/L and 0.05 mg/L, respectively.
Please have a comprehensive well water sample taken be-
fore installation to ensure proper functionality. DO NOT install
this system on a well without proper testing and recommen-
dations from the manufacturer. This will void the warranty
WARNING
New Copper lines need to be passivated for a minimum of
4 weeks before placing scale media into service. System
can run ltration only for 4 weeks before putting scale media
into service. For applications with copper concentration
greater than 1.3 ppm, please consult HALO Water Systems.
To further minimize any problem with excess copper, avoid
applying excessive ux on the inner surfaces of the pipe
and use a low corrosivity water soluble ux listed under the
ASTM B813 standard. This can be avoided by use of non-
copper pipes.
No hydrogen sulde can be present. Media will turn gray
and unit will no longer be effective.
System can run ltration only for 4 weeks before putting
scale media into service.
NOTICE: H2 ZERO® media does not reduce silica scaling.
While silica tends to have a less signicant effect on scale
formation than other minerals, it can act as a binder that
makes water spots and scale residue outside the plumbing
system difcult to remove. This 20 ppm limitation is for
aesthetic purposes.
Water known to have heavy loads of dirt and debris may
require pre-ltration (Sediment Filter SC510) prior to
H2 ZERO®.
Pressure ............ 15 psi to 90 (1.03 bar to 6.2 bar)

H2 ZERO INSTALLATION AND START UP
•Shut off electrical power or gas valves supplying water heater(s).
Note to installer: Tank may be buried 2/3 under ground..
•Turn off the main water supply to the home and open an inside
faucet to relieve any pressure within the plumbing system.
• Place the bypass valve in the upow service position.
See bypass valve modication detail pictured left.
•Connect the cold water supply to the inlet of the H2 ZERO®
system. NOTE: The H2 ZERO® system operates in the upow
mode which is opposite of a traditional ltration / softener.
See Bypass Valve Modication below.
• Connect a hose to the outlet for the purpose of draining excess carbon.
•Turn the water back on to the house. Slowly open the supply
valve to the H2 ZERO® system. Allow the tank to ll with water.
Repeat these steps three times*
Carbon tank must be ushed individually. Do not attempt to ush
the carbon tank while it is connected to tank 2.
•Backwash tank 1 for 20 minutes in the upow service position.
•Backwash in the downow service position for 10 minutes.
•Close the valve to the outlet hose drain and let system stand
pressurized for 10 minutes.
*If time permits you can soak the system for 48 hrs instead of ushing.
•Connect the outlet of the H2 ZERO® system to the cold water
supply to the house.
•Open the supply valve to the H2 ZERO® system.
•Open hot and cold faucets downstream from the H2 ZERO®
system to relieve any air from the plumbing system and water
heaters. Introduce the water inside the H2 ZERO® to home, ush
for 5 minutes. System is now installed and ready for use.
Close the faucets.
As shipped, the bypass is set-up for downow use. The arrow
shape of the handles points in the wrong direction for UP-ow
use. To convert it to upow use, pull up on the red handles
until they come off. Rotate the handle 180° and put it back
on the valve stem.

Conditioning - What to Expect & Best Practices
SPOTTING
•Spotting is normal
Remember, the beneficial minerals have been conditioned and left in your water. These conditioned
minerals will be easier to wipe up than unconditioned minerals, however if water is left to evaporate
continuously on hard surfaces, scale will begin to form. The solution is to not allow water to
evaporate on hard surfaces.
•Glass shower doors
Years of scale formations on glass doors can etch the surface of the glass and cause soap and
minerals to stick in those fissures. Using RainX® or a similar product in addition to a squeegee on
shower doors can seal pores on the glass surface causing water to sheet. This greatly reduces spots
and scale formation.
•Dishwasher
In leaving the beneficial minerals in your water this may cause some occasional spotting on dishes
and glassware. We recommend using Lemi-Shine© liquid rinse aid. This is an all natural product
and will not leave any chemical residue behind.
•Toilets
HALO Water is highly filtered to remove chemicals and disinfectants. When exposed the open
atmosphere of a toilet bowl the water can grow mildew and bacterial. This is especially true with
low flow toilets that do not fully flush away deposits and toilets that are unused for extended
periods of time. Use a product such as CLR to remove deposits. Flush ‘n Sparkle® is a
recommended to introduct chlorine to ONLY the toilet bowl without the chlorine eecting the toilet
gaskets, flapper or other components.
HARDNESS
•Total Dissolved Solids
TDS is the measurement of all dissolved solids in your water, including but not limited
to minerals The conditioning process alters the scale forming minerals so they are no
longer aggressive or harmful, but hardness tests cannot determine the dierence
between conditioned minerals and raw minerals and are ineective in determining the
performance of the HALO conditioning system. The TDS may increase slightly during
the descaling process.
•Boiling or Vaporizing Water
When boiling or vaporizing conditioned water and you may see white deposits form
on the bottom of the pan or appliance. This is a normal reaction between conditioned
minerals and extreme heat. If this causes a problem for humidifier or vaporizer use
distilled water or contact the manufacturer for more information.
•Slippery Water
The HALO Conditioning System uses no sodium or potassium. This is why you will not
experience that slimy, slippery feeling on your skin and hair. The slippery feeling is caused
by chemical additives. Instead the HALO Conditioning System provides you
with bottled water quality water.
