CAUTION
Do not use this system with water that is microbiologi-
cally unsafe or of unknown quality without adequate dis-
infection installed before or after the system.
General
If you experience any problems with these instructions, or if
any parts are damaged or missing, contact Antunes Technical
Service at [phone] (toll-free).
The Scale Inhibitor System provides mineral scale prevention
by feeding scale control compounds into the water. It should be
installed upstream of any ice making, beverage, or steam equip-
ment.
Equipment Setup
When installing the system, pay attention to the following guide-
lines:
• Do not install above electrical equipment.
• Allow space below the Scale Inhibitor Housing for Element
change out.
PLUMBING
NOTE: This system is designed to be used on tap water not
to exceed 100°F (38°C) or 100 psig (690 kPa). The kit must
be connected to the COLD water line. Do not connect the
kit to the hot water line.
The Scale Inhibitor System has the following connections:
• Inlet 3/4” NPT
• Outlet 3/4” NPT
When making a plumbing connection to the System, use a
back-up wrench on the supporting plumbing. Always use a
quality, approved pipe sealant or thread seal tape on the pipe
threads. Be careful not to get the pipe sealant inside the pipe
when making connections.
DO NOT over tighten the connections. The use of plastic fittings
when connecting to the plastic head will reduce the possibility of
cracking the head due to over tightening.
If soldered plumbing is used, do not apply heat to, or near, the
Head. The use of union (o-ring seal) connections is highly rec-
ommended for ease of installation and future servicing.
CAUTION
This equipment must be installed to comply with the
basic plumbing code of the Building Officials and Code
Administrators, Inc. (BOCA) and the Food Service
Sanitation Manual of the Food and Drug Administration
(FDA).
CAUTION
Water pressure must not exceed 100 psig. To reduce
water pressure, install a water pressure regulator and set
the water pressure to below 100 psig.

INLET WATER PLUMBING
The plumbing leading to the Scale Inhibitor System must be
flushed clear of all debris before connecting to the inlet connec-
tion of a water system. Hold a bucket at the inlet water line and
slowly open the inlet water valve. Allow the pipe to flush until all
debris is removed.
MOUNTING THE SYSTEM
Before mounting the Scale Inhibitor System, please consider the
items listed below:
• The Housing must be mounted with sufficient access for
element replacement. The Housing is 14 inches tall. An
additional 2 inches should be allowed below the clear bowl
to allow proper access when changing elements.
• The kit must be mounted with hardware capable of support-
ing 10 lbs or more of weight.
• The mounting bracket supplied with the system must be
mounted in the UP position (See Figure 2). The bracket
comes with short screws for attaching to the head and long
screws for attaching the bracket to the wall.
NOTE: Only the short screws should be used for mounting
the Head to the Bracket.
• The Head can be mounted with the inlet on the left or on
the right. When the inlet is on the left, the red pressure
relief button is on the left. Refer to Figure 2 for help in locat-
ing the Inlet and Outlet ports.
• The Scale Stick Inhibitor System kit must be installed
upstream of all consumable water access points.
• The inlet water should only be connected to the “INLET”
port on the Head. The filtered water should only be con-
nected to the “OUTLET” port on the Head. See Figure 2.
Attach the mounting bracket to the Head BEFORE attaching to
the wall.
ATTACHING TO THE INLET
Both the Inlet and Outlet connections have a 3/4” NPT female
thread. Be careful not to overtighten a fitting into the Head.
Plastic fittings are recommended for connecting to the Head.
Use a pipe thread sealant approved for use in drinking water
applications with plastic fittings.

CAUTION
DO NOT connect the Inlet water to the Outlet port
on the head.
The plumbing must be sanitized to eliminate possible contami-
nation that may have occurred during the installation process.
Liquid chlorine bleach (regular bleach, unscented 6% sodium
hypochlorite) can be used to sanitize the plumbing. The amount
of bleach to use depends on the system installed and the
amount of plumbing downstream of the Scale Inhibitor System.
Generally 10 drops (one-half ml) of bleach is sufficient to sani-
tize the bowl and associated plumbing.
CAUTION
Make sure the follow any handling or safety instructions
supplied with the bleach.
NOTE: When sanitizing the Scale Inhibitor System, make
sure the Scale Inhibitor element is not installed or is
removed from the housing before sanitizing.
1. Direct the water line from the outlet of the Head to a
drain.
2. Unscrew the Housing counter clockwise to remove the
Housing from the Head.
3. Pour the liquid chlorine bleach into the bowl.
4. Screw the Housing (containing the bleach) into the Head.
Tighten the bowl until it stops. The Housing will come to a
hard stop at the end of the thread. Use the filter wrench if
necessary.
5. Slowly turn on the water supply and pressurize the sys-
tem. Allow water to flow out of the Housing until the odor
of bleach is present.
6. Turn off the water supply and let the system stand without
water flow for at least 15 minutes to allow the bleach to
sanitize the pipes.
7. After 15 minutes without water flow, turn on the water
supply and flush until the presence of bleach is gone.
8. Shut off the water supply and depressurize the system.
NOTE: Refer to document 1010448, provided with this sys-
tem, for instructions on replacing and rinsing the Scale
Inhibitor Kit.
