Restarting Your Hot Tub in Cold Weather

If you want to start up your hot tub 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 hot tub from operating properly and possibly
damaging the equipment. We recommend you consult your dealer
for guidance before attempting to restart your hot tub under these
conditions.

14.0 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
Sundance Spas dealer who can recommend appropriate chemical
products for sanitizing and maintaining your hot tub.
WARNING:
!
WILL:
• Increase risk of contracting a waterborne illness (e.g. an
infection bacteria or virus) and/or respiratory ailments.
• Damage the equipment, components and spa shell, which
are not covered under the hot tub's warranty.
CAUTION: Never store hot tub chemicals inside the hot tub's equip-
ment bay. The equipment bay may reach elevated temperatures,
this is where high voltage electronic devices are located. This area
is not intended for storage of any kind.

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 hot tub 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 hot tub 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 hot tub clean
is severely affected as the pH moves beyond the ideal range. That is
why almost all hot tub water test kits contain a measure for pH as well as
sanitizer.
