Water Conditioning / Homeowner Maintenance
Glossary of Terms
Hardness is comprised of dissolved calcium and magnesium.
As a general rule water is considered to be extremely hard
when over 10 gpg of hardness, hard when 6-10 gpg, mildly
hard when 3-6 gpg, slightly hard when 1-2 gpg and soft when
0 gpg.
Soft Water
0–1 gpg
Moderately Hard
1.0–3.5 gpg
Hard
3.5–7.0 gpg
Very Hard
7.0–10.5 gpg
Extremely Hard
10.5+ gpg
Measurements
: Your Hamilton Beach water system registers
hardness in grains per gallon (gpg). Most water analysis reports
register hardness in milligrams per liter (Mg/L) or parts per
million (ppm). To convert either Mg/L or ppm to gpg, divide
the indicated amount by 17.1.
Example: Water report indicates total hardness of
350 Mg/L, divide this number by 17.1 to get the
gpg, which would be 20.4 gpg.
Ion Exchange
: Your water conditioning system utilizes ion-
exchange media, also referred to as resin, to effectively remove
hardness ions from the water and replace them with sodium
ions. Exhausted resin beads are rinsed with a salt solution
called “brine.” This causes the resin to exchange hardness ions
for the sodium ions, returning the resin to its sodium state.
Proportionate Brining
: Your Hamilton Beach System utilizes
an advanced microprocessor to control the amount of
regenerant proportionate to the amount of exhausted resin.
It uses enough salt to bring the system back to 100% capacity.
The microprocessor also incorporates a variable-reserve feature
to enable the system to adjust to patterns of usage, thus
maintaining high efficiency.
Manual Regeneration
Occasionally you may find it necessary to initiate a manual
regeneration. This is done by pressing the [REGEN] button on
the front of the display. (See Figure 2.) When you press the
[REGEN] button, the control performs a full regeneration of
the water conditioner immediately.
In the event the system is allowed to run out of salt, it will be
necessary to run “Back to Back” regenerations. This can be
done easily by pressing the [REGEN] button one time, waiting
at least one minute and pressing the [REGEN] button again.
-------------------------------------------------------------------------------------
Note: The second regeneration will begin immediately after the
first is completed.
-------------------------------------------------------------------------------------
“Back to Back” regenerations are necessary if full exhaustion
occurs due to low regenerate levels or system malfunction.
The system works on a highly efficient proportionate-brining
method. When the system is not aware of the lack of proper
regenerate(salt) a larger portion of the resin bed becomes
exhausted.
