WATER QUALITY MAINTENANCE
Maintaining the quality of the water within the specified limits will
serve to enhance your enjoyment and prolong the life of the
Cascade Spa’s equipment. It is a fairly simple task, but it requires
regular attention because the water chemistry involved is a balance
of several factors. There is no simple formula, and there is no
avoiding it. An indifferent approach to water maintenance will result
in poor and potentially harmful conditions for soaking and even
damage to your Cascade Spa investment. The most important thing
to keep in mind is that
preventing
poor water chemistry is much
easier than
correcting
poor water chemistry. For specific guidance
on maintaining water quality, consult your Authorized Dealer who
can recommend appropriate chemical products for sanitizing and
maintaining your Cascade Spa.
MAINTAIN HEALTHY SPA WATER
Important!
When maintaining your Cascade Spa’s water
chemistry, ensure that your cover is removed during any aggressive
treatments to allow for dissipation into the air. Take care to remove
the cover slowly and let chemicals deplete if you are uncertain if your
water is properly balanced.
Always maintain your Traditional
Spa’s
water chemistry within the following parameters:
pH:
pH is a measure of relative acidity or alkalinity of water and is
measured on a scale of 0 to 14. The midpoint of 7 is said to be
neutral, above which is alkaline and below which is acidic. In
Cascade Spa water, it is very important to maintain a slightly alkaline
condition of 7.2 to 7.8. Problems become proportionately severe the
further outside of this range the water gets. A low pH will be
corrosive to metals in the Cascade Spa equipment. A high pH will
cause minerals to deposit on the interior surface (scaling). In
addition, the ability of the sanitation agents to keep the Cascade Spa
clean is severely affected as the pH moves beyond the ideal range.
That is why almost all Cascade Spa water test kits contain a
measure for pH as well as sanitizer.
Sanitizer (Chlorine or Bromine):
To destroy bacteria and
organic compounds in the Cascade Spa water by breaking them
down into non-harmful levels which get filtered out. A sanitizer must
be used regularly, either chlorine or bromine. Sanitizing your spa
water is the most important spa maintenance you can do for
yourself.
Total Alkalinity:
This refers to the ability of the Cascade Spa
water to resist changes in pH. Controlling alkalinity can help keep
your pH in the appropriate range thereby lessening the need for pH
balancing. If the TA is too low the pH level will fluctuate rapidly from
high to low. If the TA is too high the pH will tend to be too high and will
be very difficult to bring back down.
Calcium Hardness:
This is a measurement of dissolved
calcium in the water. Calcium will help control the
corrosive nature of the spa’s water.
WARNING:
Never store chemicals inside the equipment
area of your spa.
IMPORTANT:
Do not use Hydrogen Peroxide based
sanitizers in your spa. When using Chlorine or Bromine
tablets you must use a floating dispenser. These
chemicals can have an extremely corrosive effect on
certain materials in the spa. Damage caused by use of
these chemicals, or improper use of any chemicals, is
not covered under the spa’s warranty.
OTHER ADDITIVES:
Many other additives are available
for your spa. Some are necessary to compensate for out-of-
balance water, some aid in cosmetic water treatment
and others simply alter the feel or smell of the water.
Your Authorized Dealer can advise you on the use of
these additives.
Look for these specialized cleaning attachments at your
local dealership.
WATER DIVERTER MAINTENANCE
CAUTION:
Turn off the spa from main GFCI breaker to
carry out any maintenance procedures.
Steps to clean water diverters
1. Pull the diverter cap off and rotate the diverter body
counter clock wise and pull out the assembly (Picture
1a to 1c).
2. Using clean piece of cloth, remove the dust particles or
depositions (Picture 2).
