Installation Procedure
1. Identify installation location. MultiMAX LS piping should originate shortly after incom-
ing water supply shutoff, but just after any outside water lines, such that all water intended
for interior use flows through MultiMAX LS first. This system and installation must comply with state and local laws and regulations.
2. Connect water piping. This unit has been supplied with a manually operated bypass device
which enables it to be isolated from the water service lines for maintenance and service, and
also maintain the continuity of the water supply when the MultiMAX LS is disconnected.
IMPORTANT: Make all sweat-solder connections within 6 inches of the unit 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 turn 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. Be sure not to submerse drain line end into drain, as a 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 to electrical power source. Connect power cord to a separate 120v, 15 amp,
ground fault interrupt (GFI) outlet.
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
Placing unit into service
Flush the MultiMAX LS filter with water: Locate the nearest cold water faucet tap and
open it. If there is a water softener installed downstream of the MultiMAX LS, close it’s
bypass valve until this step is completed. Slowly open MultiMAX LS bypass valve and let
water run to the open faucet tap until it runs clear. This will flush any media residual from
the filter and prepare the unit for service. Re-open water softener bypass.
Proceed to setting current time of day.

Start-Up Procedure
Setting current time of day
Setting Current Time / Day
1. Press either the Up or Down buttons to adjust current time of day by one digit. Push and
hold either up or down set button to adjust current time of day display by several digits.
User programming
User Programming Mode Options
Abbreviation Parameter Description
DO Day Override The timer’s day override setting
RT Regeneration Time The time of day that the system will
regenerate.
User Programming Mode Steps (Refer to chart above for user mode indications)
1. Press the Up and Down buttons for five seconds while valve is in service. Display will enter
programming mode. (Note: Timer will discard any changes and exit programming 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. The pre-
programmed factory recommended setting is 3 days.

User programming (cont’d)
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 12:30 AM. IMPORTANT: this regeneration time should be offset
from any water softener’s regeneration time by at least 2 hours to insure adequate regeneration pressure.
Control programming is now complete. Press the extra cycle button, and the control will
exit from the programming mode and resume normal operation.
Note:
The water purification media used in this filter has a long life expectancy, but, with use, will eventually lose it’s
effectiveness and need to be replaced. Media life can be judged from the absence of chlorine / chloramine smell in
the product water, or by testing with optional water test strips. Media replacement is possible with a kit available
from Water Control Corporation. Please contact the factory for replacement and / water testing kit availability.

Maintenance / Warranty Information
All BrassMaster and BrassMaster Plus water softeners / filters feature the Assured
Performance Modular (APM) design. If you
experience a failure of any valve compo-

module.This

andmeconsuming
fieldrepairs.
nent, the brass module can be easily removed and replaced with a factory remanufactured replacement module.
To remove module, index the bypass valve
to its “Bypass” position. Follow steps in
“Placing unit into service” to step valve
through all cycles, but do not open bypass
valve. When this procedure is performed
with the bypass closed, it will relieve any
water pressure on the unit.
Remove the stainless-steel retainer pins at
the base of the module, loosen the clips at
the bypass valve, and disconnect the drain
line and brine line. The module will now
completely separate from the tank.
Please contact your dealer or Water Control
Corporation for module support.
