INSTALLATION

4. General information
While we strongly recommend that a licensed plumber perform all
installation work, a mechanically-inclined homeowner can install
a Scale TAC-ler system. In all cases, it is critical that the installation
be done in accordance with these instructions and all applicable
plumbing codes. Be sure to obtain all required permits. If these
instructions and the applicable codes are in conflict, the relevant
plumbing/electrical code shall be followed. Equipment failure,
personal injury, or property damage can result if this equipment
is not installed properly.

Required supplies

You will need the following plumbing supplies:
- The fittings on the Scale TAC-ler system are designed to ac-
cept ¾" NPT (male) fittings.
- PVC or PEX pipe is recommended for all installations involv-
ing Scale TAC-ler series systems. While copper may be used,
it is not recommended.
- Teflon tape for thread sealing. Do not use pipe dope.
Your plumber will have these items, or they can be purchased
at your local hardware or plumbing supply store at minimal cost
(take these instructions to the store with you so the store clerk
can make sure you get everything you need). Only use galvanized
fittings for installation on galvanized pipe.
6. Installation
6.1

Select an installation location.

This product is intended for indoor installation only. This filter
may be used to treat all of the water for an entire building if the
flow rate is less than 6 gallons per minute, however, it is more
commonly used to treat only the water going to a tankless water
heater. How you plan to use this product will determine the lo-
cation of installation. In any event, select an installation location
with convenient access for regular filter replacements and main-
tenance. The Scale TAC-ler conditioner is design to be installed
after treatment equipment designed to remove iron, manganese,
hydrogen sulfide, sediment, and chlorine (if applicable). Polyphos-
phate feeders should never be placed before or after the Scale
TAC-ler conditioner.
If you plan on using this product to treat all of the water entering
the building, this filter should be installed on the main cold water
line after the pressure tank or water meter, and after most any
other water treatment equipment except a UV sterilizer or chlo-
rinator. The recommended sequence of water system/treatment
equipment if you are using this product to treat all of the water
for the building is as follows:
- Pressure Tank or Water Meter If Applicable
- Branch Line to Outdoor Irrigation
- Backwashing Iron Filter (if equipped)
- Cartridge Filters for sediment, chlorine, taste & odor
treatment.
4 | Scale TAC-ler
- Scale TAC-ler Salt-Free Hard Water Conditioner
- UV Sterilizer or Chlorinator for Disinfection of Bacteria, Virus-
es, etc. (if equipped)
If you are using this product to treat just the water going to a
specific application in the building (tankless water heater or dish-
washer for instance), it should be located on the branch water
line prior to the appliance or equipment that you are seeking to
protect from hard water scale, but after most other water treat-
ment equipment. If this filter is used after a chlorinator and it is
possible that the free chlorine level could exceed 3 ppm (mg/l), it
is recommended that you install a activated carbon filter ahead of
the Scale TAC-ler system to remove the chlorine prior to the filter.
Excess chlorine can harm the media.
6.2

Shut off main water supply and drain pipes.

Opening the highest and lowest fixtures in the house will help
drain the pipes.
MATERIAL LOSSES:
If you have an electric water heater (tankless or con-
ventional), TURN OFF all power to the water heater
before proceeding. If you fail to do this, you may cause
severe permanent damage to its heating elements.
6.3

Cut into existing main water line

Using a pipe cutter, cut out a section of your main water line at the
point where you want to install your filter system. There will prob-
ably be some water remaining in the system, so be sure to have
a bucket and some rags handy to clean up any small spills. Make
sure that the section of water line you remove is appropriately
sized such that all of the components of the system including the
shut-off-valves, adapters, and the black filter cap will fit snuggly
when assembled. If in doubt, cut a smaller section at first – you
can always remove a slightly larger section upon final assembly
if necessary.
6.4

Mount on wall

Attach the mounting bracket to the housing cap using the 4 lag
bolts and 4 of the washers provided, then securely mount the
housing to the wall using the 4 pan-head wood screws and the
remaining 4 washers. If you are securing the system to drywall
or plaster, be sure that the wood screws reach a wood stud, or
alternatively, install appropriate anchors for secure support. If
mounting to concrete or other surface, you may need to pur-
chase alternative fasteners from a hardware store. Be sure to
allow enough space below the housing cap to accommodate the
white housing sump plus a minimum of an additional 3 inches of
clearance.
