Warning!
Consuming water with combined nitrate/nitrite levels above the USEPA MCL (Maximum Con-
taminant Level) of 10 PPM (10 mg/L) can cause breathing/oxygen absorption problems in in-
fants and animals — and may be linked to certain cancers.
Always install and operate this system according to manufacturer instructions. Test water every
six months to verify proper system operation.
Water Control offers inexpensive, non-certified test services (the first 2 test bottles are included
free with system).

Installation Procedure
1. Identify installation location for NitraMAX system. Piping should be such that all house-
hold water, with the exception of outside hydrants, flows through NitraMAX. This system
and installation must comply with state and local laws and regulations. Always install Nitra-
MAX down stream of any other water treatment equipment.
2. Connect water piping. This unit has been supplied with a manually operated bypass device
which enables the softener to be isolated from the water service lines for maintenance and
service, and also maintain a constant water supply when the NitraMAX is disconnected.
Important: Make all sweat-solder connections within 6 inches of NitraMAX before applying
threaded fittings to supplied bypass valve. Overheating may cause damage to valve. Turn
supplied bypass valve to “Bypass” position and make connections to household water lines.
Leave unit in “Bypass” position until startup procedure.
3. Connect drain line. Remove barbed drain line fitting from parts bag. Apply thread seal
tape to threads and install into the female threaded opening on the back side of the control
valve. Connect 5/8” drain line (supplied in parts bag) to barbed end of drain line fitting and
run to a nearby drain.
IMPORTANT: It is highly recommended that a hose clamp be used to secure tubing to
drain fitting to ensure tubing from being removed during elevated pressure situations.
Be sure not to submerse drain line end into drain, as an 1 1/2” minimum air gap must be
maintained to prevent potential backflow hazard. Firmly secure at drain, while maintaining
a minimum 1 1/2” air gap (See detailed drawing on back side of piping diagram).
4. Connect brine line. Connect 3/8” brine line (supplied in parts bag) to fitting on brine tank
and on the control valve. Tighten both fittings with an adjustable wrench.
5. Install brine tank overflow line. Install overflow fitting (supplied in parts bag) into hole in
side of brine tank. An owner-supplied overflow line should then be attached and run to a
nearby drain. Failure to run overflow line could cause flooding and water damage should
the brine tank overflow.
6. Connect to electrical power source. Connect power cord to a separate 120VAC, 15Amp,
ground fault interrupt (GFI) outlet.
7. Add 1—2 bags of sodium chloride or potassium chloride to the brine tank. WCC recom-
mends pellet salt from manufacturers such as Morton or Diamond.
Proceed to start-up procedure.
Note: This system is not intended to be used for treating water that is microbiologically
unsafe or of unknown quality without disinfection before or after the system.

Start-Up Procedure
1. Fill the mineral tank with water
 Keep NitraMAX in BYPASS
 Press and hold the extra cycle button for 5 seconds, display will indicate BW, Backwash
cycle.
 Push extra cycle button once and let go, display will indicate BD, Brine Draw cycle.
 Push extra cycle button again and let go, display will indicate RR, Rapid Rinse cycle.
 Slowly open bypass valve and allow water to flow for 2-4 minutes. This will allow the
media in the tank to become saturated.
 Open bypass valve to the service position.
 Push extra cycle button once and let go, display will indicate BF, Brine Fill cycle.
 Allow timer to fill the brine tank for the entire time on the display. The unit will advance
to the service position when completed.
 Push extra cycle button for 5 seconds, this will start a manual regeneration from start-to-
finish. This will take approximately two hours.
Start-up procedure is now complete.
The unit is now pressurized with water and ready for service.
Proceed to setting current time of day.

User Programming Mode Steps (Refer to chart above for user mode indications)
1. Press the Up and Down buttons simultaneously for five seconds while valve is in service.
Display will enter programming mode. (Note: Timer will discard any changes and exit pro-
gramming mode if any button is not pressed for sixty seconds.)
2. Set Day Override: This setting specifies the maximum number of days between regenera-
tion cycles. System will regenerate regardless of usage if the days since last regeneration
cycle equals the day override setting. This ensures regular regeneration periods. In areas
where nitrates range between 0-50 PPM, this setting should not exceed 6 days. If nitrate lev-
els exceed 50 PPM, please contact Water Control for a setpoint recommendation.
Setting Current Time / Day
1. Press either the Up or Down button to adjust current time of day by one digit. Press and
hold either the up or down button to adjust current time of day display by several digits.
Ensure the AM/PM setting matches the current time of day.

User programming (cont’d)
Control programming is now complete. Press the extra cycle button and the control will
exit from the programming mode and resume normal operation.
3. Adjust Regeneration Time: Press the Extra Cycle button to advance to next option. This
setting determines the time of day that the unit will enter the regeneration cycle. The most
common / default setting is 2:00 AM. If additional equipment is installed, ensure the regener-
ation times are offset by a minimum of 2 hours.
4. Set Water Hardness: Press the Extra Cycle button to advance to next option. Set the hard-
ness of the incoming water (Grains per Gallon). For each PPM of iron, add 4 Grains per Gal-
lon to this setting. This will determine the amount of water usage allowed between regenera-
tion cycles. NOTE: If combined Nitrate+Nitrite levels exceed 50 PPM, contact Water Con-
trol for additional setpoint instructions.
5. Set Fixed Reserve Capacity : Press the Extra Cycle button to advance to next option. Set
the Fixed Reserve Capacity for the household. This is the amount of water needed in reserve
to reach the delayed regeneration time. Standard setting is 50 gallons for each person in the
household.
Start-Up Procedure
After complete installation of unit, dilute 1/2 cup of unscented laundry bleach in 3 gallons of
water, and add to brine tank. Initiate a manual regeneration by depressing the extra cycle but-
ton. Allow the unit to complete its cycle and advance to the “Service” position. The unit is now
sanitized and ready for operation.

Maintenance / Warranty Information
All BrassMaster Plus water treatment systems
feature the Assured Performance Modular
(APM) design. If you experience a failure of
any valve component, the brass module can
be easily removed and replaced.
Reference the BrassMaster and BrassMaster
Plus Technical Video Library on our website
(link is provided below) for detailed steps on
how to remove the module. The required
(downloadable) form to have your module
replaced is also located at this site.
Please contact your dealer or Water Control
Corporation for module support.
Nearly all serviceable
parts lie within the
removable / replaceable
APM module.
This eliminates costly and
time consuming field repairs.
Salt Maintenance
Failure to maintain salt in the brine tank will allow nitrates into your water!
You must keep salt in the brine tank. The salt tank operates best when the salt level is below
half full. Excessive brine tank filling may cause a salt “bridge” to form. The salt pellets wedge
against each other preventing the salt pellets from fully submersing. This will prevent a proper
brine solution from forming which will not allow the NitraMAX to regenerate properly. The
NitraMAX will regenerate but not recondition the media. A salt bridge can be broken up using a
broom handle or similar rod. Carefully pound it into the salt and the pellets will collapse. After
loosening the salt pellets wait 2 hours and start a manual regeneration. A second system regen-
eration may be needed to fully recondition the media. You should only use sodium chloride or
potassium chloride pellet salt for NitraMAX systems. Other types of salt (rock or snow melting)
will contain dirt and chemicals that will affect your system.
