12.8 restarting Your spa in Cold weather
If you want to start up your spa after it has sat empty for a time in
freezing temperatures, be aware that the water remaining in certain
sections of the piping may still be frozen. This situation will block water
flow preventing the spa from operating properly and possibly damaging
the equipment. We recommend you consult your authorized Jacuzzi
dealer for guidance before attempting to restart your spa under these
conditions.
13.0 water Quality maintenance
To decrease the risk of contracting a waterborne illness (e.g. an infection,
bacteria or virus) and/or respiratory ailments, maintain water quality
within specified limits. This will enhance your enjoyment and prolong
the life of the hot tub’s equipment. Doing so requires regular attention
because the water chemistry involved is a balance of several factors.
Procrastination in regard to water maintenance will result in poor and
potentially unhealthful conditions for soaking and even damage to your
hot tub investment. For specific guidance on maintaining water quality,
consult your Authorized Jacuzzi dealer who can recommend appropriate
chemical products for sanitizing and maintaining your hot tub.

13.1 pH Control
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 spa water, it is very important to
maintain a slightly alkaline condition of 7.4 to 7.6 pH. Problems become
proportionately severe the further outside of this range the water gets.
A low pH will be corrosive to metals in the spa equipment. A high pH will
cause minerals to deposit on the interior surface (scaling). In addition,
