The ScaleBlaster unit can be installed on a horizontal or
vertical Copper, PVC, CPVC and/or PEX pipe
If a magnet will stick to your incoming water line, you have galvanized
pipe. In this case, you will need to replace a small section of pipe, about
10-11 inches, with either pvc or copper pipe.

Before You Start Installing
Finding The Main Cold Water Pipe
The water shutoff valve is on the main cold water pipe. Install the on this
pipe as close to where it comes into the house as possible. This will ensure that the outside
spigots and kitchen are being treated.
Well Water Installation
For customers that are on a private well, the best place to install the ScaleBlaster unit is after
the well’s pressure tank. If that is not possible, the ScaleBlaster unit can be installed prior to
the pressure tank.
Softener Loop
The ScaleBlaster unit can be installed on a softener loop. Installing on a softener loop gives
treatment to all of the water that a softener would treat. Water to the kitchen faucet and outside
spigots may not be treated when the ScaleBlaster unit is installed this way.
Find The Pipe Size
If you do not know the actual pipe size, place a ruler in front of the pipe and measure the
outside diameter. Use Table 1 to determine the size of the pipe. The actual pipe size is always
rated by the inside dimensions of the pipe.
A Tight Wrap Is Very Important
It is extremely important to the effectiveness of your ScaleBlaster unit that the signal cable
wire be wrapped correctly. If there are any gaps between the wraps, your ScaleBlaster unit
will not work to its full capacity.

If you cannot access the cold water pipe before it splits
Follow the main cold water pipe back as far as possible from the water heater and install the
ScaleBlaster there. By doing this, all of the home's water may not be treated, and in some
cases only the hot water may be treated. However, the hot water line is the most important to
treat and is the main cause of lime scale formation.

See chart on pages 6 & 7 to wrap the coil and to determine the proper number of wraps.

LOCATION OF THE SB-75 UNIT
1.) The most desirable place to install the unit is on the main water line that enters the house.
2.) The power unit should be mounted on a wall or other solid surface within five feet from an electrical
outlet and within ten feet from where the pipe will be wrapped.
3.) Once the main water inlet pipe to the house is located, identify a section of pipe that is at least 12
inches straight and at least two feet away from any major electrical interference, example - an
electric motor.

Important! For best results, wrap signal cable on a
straight section of pipe of 12” or more. Keep the
signal cable as far away as possible from tees,
elbows, couplings, valves and any curved pipe.
Keep signal cable at

from any major

No more than

MOUNTING THE POWER UNIT
HOLES FOR MOUNTING
INSTALLING THE SIGNAL CABLE
Bottom of unit in detail. This is where the power supply gets plugged in and the signal cable
wires are inserted. Make sure the two bare wires do not short out by touching each other.
The unit must be mounted indoors in an upright vertical position on a wall or other
non-enclosed area. The picture below shows the location of the mounting holes. The
installer must supply the mounting screws for the type of surface the unit will be
mounted on. (We recommended a number 8 screw.)

Terminal Block Holes
To get wire into terminal block holes, twist
bare cable and insert into one of the
terminal block holes fully then gently
tug wire to insure the wire is locked into
place.
Release Button (button below the wire

To remove the wire, push the button below

driver) and pull the wire out of the hole.
Not the wire holes. Do not put wire in
these holes below the release buttons.

Wrapping the pipe with the
ScaleBlaster Signal Cable
1.) Fully insert the pre-stripped end of the signal cable into one of the two signal terminal block holes,
then gently tug the wire to insure it is locked into place. (See Illustration B on page 5)
2.) Route the signal cable to the inlet pipe. Hold cable parallel and next to the pipe.
3.) Wrap one of the cable ties tightly so that the signal cable is secured to the pipe. (Figure A)
4.) Wrap the loose end of the signal cable securely around the pipe - in any one direction – the proper
number of turns as noted in Chart A.
5.) Make sure the wraps are flush against one another, wrapped tightly and not overlapping. Continue
until you reach the recommended number of wraps.
6.) Wrap a second cable tie at the end of the wrappings securing the signal cable tightly. (Figure B)
7.) Route the loose end of the signal cable back to the
power box. Trim excess cable to length.
8.) Carefully strip the outer plastic shield from the end of the
signal cable leaving1/4” to 3/8” of bare cable. Twist the
bare cable and insert the end in the other terminal block
hole on the power box then gently tug the wire to
insure it is locked into place. (see Illustration B
on page 5)

COPPER PIPE INSTRUCTIONS
1.) Follow the same instructions in steps 1-6 for PVC, CPVC and PEX pipe. Use Chart B for Copper
2.) Instead of a single coil wrapping around the pipe, a second one is added for copper pipe.
3.) YOU MUST KEEP THE SECOND WRAPPING IN THE SAME DIRECTION AS THE FIRST! Wrap
right over the top of the first layer continuing in the same wrapping direction as the first layer –
clockwise or counterclockwise. This second layer must also be tight and touching the prior wrap.
(Figure C)
4.) Wrap a third cable tie around the pipe and both wires.
Pull the cable tie tight. (Figure D)
5.) Follow same instructions in steps 7-8 for PVC, CPVC and PEX pipe.
ACTIVATING THE SYSTEM
1.) Once the power unit has been installed and the pipe has been wrapped, insert the connector end of the
AC power adaptor into the power unit. (See Illustration A on page 5)
2.) Plug in the transformer end of the cord into a 110-volt electrical outlet.
3.) Operation of the ScaleBlaster SB-75 system can be confirmed by observing the illumination of the
LED indicator located on the face of the power unit. Power on - green light on far right side will stay
lit (Figure E). When pipe is wrapped and unit is turned on the far right light will stay lit and the other
lights will oscillate back and forth (Figure F).
MAINTENANCE
The best feature of the ScaleBlaster SB-75 is that there is NO MAINTENANCE REQUIRED. No salt,
batteries, moving parts or costly repairs. Just check the LED light for proper operation.

ENJOYING THE SCALEBLASTER SYSTEM
There is no maintenance with the ScaleBlaster unit itself! No bags of salt to haul
around, wasted water or batteries to change. Best of all, you are protecting the
environment!
Allow up to 90 days to realize the full effects. Initial descaling may make things worse
for awhile, especially in the dishwasher and aerators. This is normal! Simply clean out
the screens or aerators. With dishwashers, we recommend cutting back on soap usage
(unless you have been using a water softener). In July of 2010, manufacturers of
dishwasher soap detergents cut back on phosphates - resulting in an increase in spotting
and cloudiness. We recommend using Cascade Action Pacs with Dawn or Cascade All-
in-one Action Pacs for best cleaning results. Another product that works best is Lemi
Shine. You may also add white vinegar in the rinse cycle.
After the first 90 days, we strongly recommend you drain out your water heater. You will
be amazed at what ScaleBlaster has cleaned out of your pipes!
