Sumo Water Softener Owner's Manual
System Maintenance and Install Guidelines
Adding Salt
Ensure that the salt level in the brine tank or cabinet is always above
the water level.
Use a quality grade of block or pellet salt processed especially for use in
water softeners. DO NOT USE ROCK SALT.
Water Pressure
Inlet water pressure range of 1.5 – 8 bar (22 – 116 psi) is required for
valve to operate effectively.
Existing Plumbing
Existing plumbing should be free from lime and iron buildup. Replace
plumbing that has heavy lime and/or iron buildup. If plumbing is
clogged with iron, install a separate iron filter unit ahead of the water
softener.
System By-pass
Always provide for the installation of a by-pass valve if unit is not
equipped with one.
