NORDIC HOT TUBS | OWNER’S MANUAL |

WATER QUALITY
As the owner of a Nordic Hot Tub it is important to maintain
proper water quality to keep your hot tub and equipment
in excellent condition. Please consult your Spa and Pool
Professional on how to maintain proper water quality. If your
spa is equipped with an Ozone Generator, it will produce
ozone only when the hot tub is running on low speed or
during a filter cycle (2-pump systems). It cannot be used as
the sole means to maintaining safe spa water- you will need
to use sanitizers to keep your water sparkling and clean.
OZONATOR
Some models include an ozonator. Ozone reduces the
required amount of sanitation chemicals required to keep
your water clean, but it does not completely eliminate it.
Any time pump 1 is running, ozone is being generated
and injected into your hot tub via a small jet located in the
footwell. The 2-pump systems only turn the ozonator on
when it is running in a filter cycle.
SANITATION
Sanitizers are intended to kill bacteria and keep water
clean. Nordic recommends Dichlor Granular Chlorine as
a sanitizer. You will need to decide which brand sanitizer
you wish to use. Please consult with your spa retailer for
what is available and its proper use. They will have the best
understanding of what is required to keep the water in your
area balanced.
WARNINGS:
• The improper use of any sanitizing system including
Dichlor Granular Chlorine could negate our warranty.
WHY?
o Undissolved granules left on the shell surface can
discolor, chemically burn, and blister the shell surface.
This includes areas of the shell above the water line.
o Slowly sprinkle the correctly measured granular
products into the water. Directly over the filter basket
or floating weir is an ideal location. For the Bella, slowly
pour the granules near the side-mounted skimmer face.
• WARNING: Do not confuse the term “Dichlor” with
“Trichlor”- they are not the same. Trichlor is very
acidic and will damage several components of your
new hot tub.
• The use of a floater can potentially damage the shell of
your hot tub and is not covered under warranty. Why?
o Floating dispensers have a tendency to end up staying
in 1 spot (near the filter). This causes the chemicals to
disperse very quickly and it will be hard to manage the
proper levels. Once the chemicals are gone, algae and
bacteria can grow quickly.
o The increased chemicals getting continually drawn into
the filter can stain or fade the shell. This is not covered
under warranty.
o Floaters are typically loaded with larger tablets or bars.
Small pieces of the chemicals (larger than granular
products) can break off and settle on the seats and floors.
Those can chemically burn, stain, or blister the surface.
• Nordic does not recommend the use of any Bromine
product. Why?
o Bromine can fade or discolor your shell surface. This is
not covered under warranty
o Bromine off-gassing combined with ozone can be
dangerous in higher concentrations
• Do not use pool chemicals including muriatic acid or
household bleach (liquid sodium hypochlorite)
• Do not use tablets or sticks. Only use granular products.
• Do not use polyhexamethylene biguanide products
(hydrogen peroxide)
• Failure to maintain proper chemical balance (pH,
Alkalinity, and Hardness) could also negate your warranty.
• The use of Salt Systems will void the warranty.
Remember: Your Nordic dealer is a trained chemical
specialist and can assist you with your questions and water
analysis if requested.
ADDING CHEMICALS
1. Lift the cover and fold it back and out of the way.
2. Turn the pumps on high speed.
3. Slowly sprinkle the correctly measured granular products
into the water. Directly over the filter basket or floating
weir is an ideal location. For the Bella, slowly pour the
granules near the side-mounted skimmer face.
4. Let the spa run until it reaches the time-out time (ap-
proximately 15 minutes) at which point it will drop to low
speed. Let it run on low speed for an additional 15-20
minutes before reinstalling the cover to allow all of the
off-gassing to finish.
Note: Chemical off-gassing can damage your cover and
void its warranty.
5. Reinstall the cover and latch or lock it.
Note: Chemical off-gassing can damage your cover and
void its warranty.
