Hydrotech SL844-12 Scaleless POE Residential System - Manual (Page 6)

Notes to the Installer.
The Scaleless system differs from a conventional softener or media filter in a number of key respects.
• The system is light and only partially filled with media. This is normal. The UP-flow operation of the system requires a lot of
freeboard to allow the bed to fully fluidize.
• The system has no underbed so you can tip the system over without any fear of upsetting the media. This makes trans-
portation and installation much easier than conventional systems.
• Because the Scaleless system operates in the UP-Flow mode, the tank connections are opposite of what you’re used to.
• Please see the “important note about iron, manganese and copper” above.
• Please see the note about “Using Scaleless with other water treatment equipment” on the previous page.
An important note about iron, manganese and copper in the water supply.
Iron and Manganese
Just as with conventional water softening media, Scaleless needs to be protected from excess levels of certain metals that
can easily coat the active surface, reducing its effectiveness over time. Public water supplies rarely, if ever, present a prob-
lem, but if the water supply is from a private well confirm that the levels of iron (Fe) and manganese (Mn) are less than 0.3
mg/L and 0.05 mg/L respectively. Copper should be less than 1.3 mg/L.
Copper
Copper usually originates from new copper plumbing upstream of the Scaleless system. If this condition exists, we recom-
mend waiting 3-4 weeks before placing the system in operation. This will allow the copper surfaces to be fully flushed and
develop a natural protective surface. To further minimize any problem with excess copper the plumbers should be advised
to avoid applying excess flux on the inner surfaces of the pipe and to use a low-corrosivity water soluble flux listed under the
ASTM B813 standard. Once the plumbing connections are complete, place the Scaleless system in bypass prior to following
the startup procedure and flush the plumbing for at least 10 minutes.
Cautions!
• Do not let the system freeze. Damage to the tank may result.
• System must be operated in a vertical position. Do not lay it down during operation. The system may be placed in any
position for shipping and installation but must be operated in the vertical position.
• Place the system on a smooth, level surface. Because the system operates in an UP-Flow, fluidized bed mode, having a
level surface is more important than with a softener or media filter.
• A bypass valve should be installed on every system to facilitate installation and service.
• Observe all local plumbing and building codes when installing the system.
