Maintaining The Proper Ph - Whirlpool 11-0086-11 Owner's Manual

7 - pH Up: The effects of low pH can be rapid sanitizer loss, eye and
skin irritation, expedited corrosion of metals, as well as staining through-
out the spa. pH up can be purchased from your dealer in either liquid or
solid granular form. Please see your dealer for recommended dosage.
8 - Metal Protect or Remover: Also called stain and scale defense,
metal protect inhibits staining and scaling in your spa. It will also pre-
vent calcium build-up on the surfaces of your spa. Regular use will help
protect your spa surface as well as your plumbing, your pumps, and
even your heater.
9 - Spa Shock: Non-chlorine spa shock contains Potassium Monop-
ersulfate and is an oxidizer that works well with mineral, chlorine and
bromine systems. Regular use of spa shock can substantially reduce
the need for sanitizing by up to 50% and will continually remove inor-
ganics from the water. Best of all, you can bath in only 15 minutes after
application.
10 - Ascorbic Acid: Vitamin "C." Can be used as an acidic reducing
agent in the removal of difficult metallic stains from underwater surfac-
es. Oxalic acid can be used in a similar manner.
MAINTAINING THE PROPER pH BALANCE
The pH factor is a measure of the relative acidity or alkalinity in the wa-
ter. It is measured on a scale of 1 to 14. Pure water has a value of 7,
which is neutral. Any value above 7 is alkaline, and any value below 7
is acidic. You should maintain a slightly alkaline pH level, between 7.2
and 7.8, in the hydrotherapy spa. Severe problems can occur when the
pH balance is not maintained within this range. If the pH level exceeds
7.8, dissolved minerals can build up and clog the plumbing in the spa
jet unit. If the pH level falls below 7.2, the acid level in the water will
begin to corrode the metal parts in the spa jet unit. Also, the sanitation
agents in the water will not be effective if the pH level is not properly
maintained. Damage caused by improper pH levels is not covered un-
der the warranty. To maintain the proper pH level, you should test the
pH of the water regularly. To test the water, purchase a pH test kit at a
pool and spa supplier. The pH reading should be between 7.2 and 7.8.
If the level is too low, add a pH increaser (usually soda ash). If the level
is too high, add a pH reducer (usually sodium bisulfate). Test the water
again after five minutes. See the instructions with your pH test kit for
l information about testing and adjusting the pH.
