SYSTEM DIAGNOSTICS
CHECK LIST
More than 90% of problems affecting the efficiency of
a refiner system can be identified in 9 minutes or less. Follow this
diagnostic schedule below.
Start with Step 1, then follow each step in sequence to ensure
proper diagnostic procedures.
1. CHECK FOR PROPER INSTALLATION
A.
Is the pipe from the pressure tank to the refiner
unit attached to the inlet port of the control valve?
B.
Is the pipe from the refiner unit to the water heater
attached to the outlet port of the control valve?
C.
Is the drain line of adequate diameter? Drain line
must be sized to prevent back pressure from
reducing backwash flow rate below minimum for the
model installed.
D.
Has the drain line been "kinked"? A kinked drain line
must be replaced.
E.
Is the drain line installed in a way that it will freeze in
cold weather?
F.
If the system incorporates a standard air-to-water
pressure tank, does it have the required deep well air
volume control (air release valve) and is it functioning?
(Proper installation of this type of pressure tank should
have inlet from pump higher than outlet to service.)
NOTE
Typical examples of minimum drain line diameters are:
5/8" ID when drain is up to 15 ft from unit and backwash water
discharge point is slightly higher than the control valve
3/4" ID when drain is 25 ft away and/or drain is installed overhead
2. CHECK PH, IRON AND MANGANESE CONTENT
OF TREATED WATER
Is the treated water pH reading less than 6.7 (8.2 when
manganese is present)?
If yes, replenish the media with MpH adder and check the
bed for "channelling".
3. CHECK PUMPING RATE
Do not refer to a pumping rate curve for this data. Follow the
instructions found on Page 7. Is the measured pumping rate
less than the backwash rate of the refiner? If yes, increase the
pumping rate by first reducing the system operating pressure.
If the pumping rate is still too low, replace the pump.
4. REVIEW OTHER USES OF WATER IN ADDITION
TO NORMAL DOMESTIC PURPOSES
(e.g. geothermal heating/cooling, swimming pool, lawn
irrigation, farm animal watering, etc.)
Have any high demand water uses been added subsequent
to the installation of the refiner system or overlooked when
originally sizing the system? If a high demand situation exists,
resize the system using continuous service flow rate data.)
DURING REGENERATION
AUTOMATIC BYPASS
The regeneration cycle lasts approximately 120 minutes, after
which treated water service will be restored. During regeneration,
untreated water is automatically bypassed for use in the
household. Hot water should be used as little as possible during
this time to prevent hard water from filling the water heater.
IMPORTANT:
This is why the automatic regeneration is set for
sometime during the night and manual regenerations should be
performed when little or no water will be used in the household.
NEW SOUNDS DURING REGENERATION
You may notice new sounds as your water refiner operates.
The regeneration cycle lasts approximately 2-1/2 hours.
During this time, you may hear water running intermittently
to the drain.
PLUMBING SYSTEM
CLEAN-UP
The following procedures are guidelines only but have proven
successful in most instances. Under no circumstances should any
procedure outlined below be followed if contrary to the appliance
manufacturer's instructions. Should there be any questions
concerning the advisability of performing a procedure, it is
strongly recommended your local NUVIA® dealer be
consulted prior to performing the procedure.
The plumbing system and water using appliances that have been
exposed, even for a short time, to iron-fouled water need to be
cleaned of the precipitated iron that has collected in them. If not
cleaned, the iron bleed (staining) will continue to be a problem.
Depending on the amount of iron in the water and the length of
time the water system has been exposed to iron fouling, select
from the following procedures those that apply to the type of
system and appliances that need to be cleaned to assure
iron-free water at the point of use.
