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 com-
ply 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 apply-
ing 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” mini-
mum 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.
