WATeR FeATuRe
Vista®, grandee®, envoy ®, and Aria® spas are equipped with a
BellaFontana® water feature. This water feature can be turned on or off
when the two-speed pump is on low speed (tranquil mode) or high speed.
To function correctly, the water feature on/off lever must be placed in the full on position only .
If the lever is not in the full on position when the pump is on high
speed, it is likely that the water feature will project water substantially
farther out into the spa as the on/off lever is opened. This is not proper
operation. If this occurs, the pump should be turned off, the water
feature lever rotated to the full on position and the pump turned on again.
CauTIon: Partial blockage of water flow at entrance of water feature
will cause the water to flow farther into or over the spa.
Vanguard ® and Sovereign ® models have the Soothing Stream
feature. The water feature is located on the front right corner of the spa.
A lever is used to adjust the water from full flow to completely of f. The
circulation pump of the spa powers the water feature allowing the water
to run all of the time if desired. Turning the water feature lever to it’ s full
clockwise position will shut the water feature off.

prolongs the life of the spa components and will make the water
more comfortable. your dealer can guide you through the process of
achieving and maintaining perfect water in your spa, given your local
conditions. your program will depend on your water’s mineral content,
how often you use your spa, and how many people use it. Watkins

ChEMICAl SAFETY
When using chemicals, read the labels carefully and follow directions
precisely . Though chemicals protect you and your spa when used
correctly , they can be hazardous in concentrated form. Always observe
the following guidelines:
• Allow only a responsible person to handle spa chemicals. keep them
out of the reach of children.
• Accurately measure the exact quantities specified, never more. do not
overdose your spa.
• Handle all containers with care. Store in a cool, dry , well ventilated
place.
• Always keep chemical containers closed when not in use. Replace
caps on their proper containers.
• don't inhale fumes, or allow chemicals to come in contact with your
eyes, nose, or mouth. Wash your hands immediately after use.
• Follow the emergency advice on the product label in case of
accidental contact, or if the chemical is swallowed. call a doctor or the
local Poison control center. If a doctor is needed, take the product
container along with you so that the substance can be identified.
• don't let chemicals get on surrounding surfaces or landscaping. don't
use a vacuum cleaner to clean up chemical spills.
• Never smoke around chemicals. Some fumes can be highly
flammable.
• don't store any chemicals in the spa equipment compartment.
hOw TO Add ChEMICAlS
TO ThE wATER
ImporTanT: All spa water chemicals, including granulated dichlor,
MPS, granulated pH increaser or decreaser, granulated total alkalinity
increaser, liquid stain and scale inhibitor, and liquid defoamer must
always be added directly into the filter compartment while the jet pump
is running in its high speed mode, and it must run for a minimum of ten
minutes.
To administer spa Water Chemicals:
1. Fold back the cover . carefully remove and set aside the filter
compartment cover.
2. on your control Panel, push the cleAN soft button (on home screen)
to turn on the jet pump.
3. carefully measure the recommended amount of chemical and slowly
pour it into the filter compartment. use care not to splash chemicals
on your hands, in your eyes, on the spa shell surface, or on the spa
cabinet.
4. Replace the filter compartment cover . After ten minutes, the jet pump
will automatically shut off to complete the procedure. close and secure
the cover.
danGer: Risk of drowning: Never leave an open spa unattended!
ImporTanT: After administering a super chlorination treatment or
non-chlorine shock to your spa, leave the cover open for a minimum
of 20 minutes to allow the oxidizer gas to vent. A high concentration of
trapped oxidizer gas which may exist as a result of the shock treatment
(not daily sanitation) may eventually cause discoloration or vinyl
degradation to the bottom of the cover. This type of damage is considered
chemical abuse and is not covered under the terms of the limited warranty .
Water Quality and Maintenance

FUNdAMENTAlS OF
wATER MAINTENANCE
• Testing: Test the water weekly or each time the spa is used with
convenient FreshWater 5-way test strips or more accurate liquid/
tablet reagent test kit per instructions. critical parameters: sanitizer
level, pH, calcium Hardness (cH), and Total Alkalinity (TA). Store test
equipment in a dark, cool, dry place to maintain potency .
• Water filtration: The 100% no by-pass 24 hour filtration used in
Hot Spring® spas provides the best approach to keeping water clean
by constantly circulating sanitizer and removing waste from the spa.
Regularly inspect and clean filters for peak performance.
• Chemical balance/pH Control: It is important to adjust the primary
water parameters (Total Alkalinity , calcium hardness, pH) into the
recommended ranges so
that they are stabilized or
balanced. Balance the
water chemistry every time
you fill the spa with new
water and then during the
life of that body of water.
keeping the water in
balance prevents damage
by holding the pH in a
safe range and preventing
calcium scale formation
on spa equipment. A low
pH can damage metal
components whereas a
high pH can cause high levels of calcium to form scale. your dealer
should provide a detailed water chemistry orientation soon after your
new spa is filled for the very first time.
• The following three water components must be kept in balance to avoid
damage to the spa. do balance these components in the order they
are listed here as each will help you balance the next using a minimum
amount of chemicals.
1. calcium Hardness (cH) – cH is the measure of the amount
of dissolved calcium in the water. low levels can make the
water corrosive and high levels cause scale formation of spa
components. The recommended cH reading is between
50 - 150 ppm. A hardness of 100 ppm is recommended with the
Ace System. If the cH level is too low, raise it with Hot Spring
FreshWater calcium Increaser, and if the cH level is too high,
lower it with the V anishing Act ® calcium remover per instructions.
once in balance, the cH reading normally remains stable until
new water is added. great care must be taken when filling the
spa from a water softener to ensure that the calcium remains in
balance and avoid damage to the spa.
2. Total Alkalinity (TA) - TA is a measure of the water’s ability to
resist changes of pH or buffer capacity. A low TA allows the pH
to fluctuate easily . The recommended TA reading is between
40 - 120 ppm. To raise the TA, use Hot Spring FreshWater pH/
Alkalinity up (sodium hydrogen carbonate). To lower the TA, use
Hot Spring FreshWater pH/Alkalinity down (sodium bisulfate).
once the TA is balanced, it normally remains stable until the next
drain/refill. We recommend you check the TA reading once per
month. Raising/lowering the TA may cause the pH readings to
fluctuate widely . Ignore the pH readings on the test strip while you
are balancing the TA.
3. pH - The pH is the measure of the acidity and alkalinity.
Maintaining the proper pH level will optimize the effectiveness

of the sanitizer, preventing damage to the spa and physical
discomfort for spa users. A low pH dissipates sanitizer, causes
corrosion, and irritates spa users. A high pH level will neutralize
sanitizer, promote scaling and cloud water. The recommended
pH reading is between 7.2 - 7.6. To lower the pH level, use Hot
Spring FreshWater pH/Alkalinity down (sodium bisulfate). To raise
the pH level, use FreshWater pH/Alkalinity up (sodium carbonate).
• Water Conditioners: Spa fill water varies from location to location
and user to user, therefore it is important to consult with your dealer for
an appropriate program.
a. Vanishing Act® – High levels of calcium and some minerals can be
removed from the water with the single use V anishing Act. High
calcium levels can cause scale formation on the spa equipment
and shell.
b. clean Screen® pre-filter –The clean Screen pre-flter should be
used at every fill and top-off to remove contaminants from the
fill water, especially iron, copper, and manganese. Many water
sources including well water contain high concentrations of
minerals that can cause staining of the shell and plastics.
c. Stain and Scale control – For water high in calcium and minerals,
it may be necessary to use an anti-scalant like Stain and Scale
control. As water evaporates from your spa and new water is
added, the amount of dissolved minerals like calcium, copper, iron,
and manganese will increase. (Minimize evaporation by keeping
the cover on the spa whenever possible.) High iron or copper
content in the water may produce green or brown stains on the
spa.
d. Foam Inhibitors - Soap is introduced into the spa water from
users’ bodies and swimming apparel and can cause the spa
water to foam when the jets are used. low levels of calcium
hardness (soft water) can increase foaming. Although ozone and
Ace can oxidize soap residual, it may become necessary to add
Foam Inhibitors to suppress the foam. excessive soap in the
water may require a water change to resolve.
• oxidizers: ozone and Monopersulfate (MPS) are oxidizers used to
prevent the buildup of contaminants, maximize sanitizer efficiency,
minimize combined chlorine, and improve water clarity . They are to be
used in conjunction with eP A registered sanitizers. The FreshWater ®
III high output ozone system uses corona discharge technology
to produce a high concentration of ozone which is injected into the
spa water 24 hours per day . Hot Spring FreshWater chlorine-Free
oxidizer, Monopersulfate (MPS) is a granular oxidizing chemical.
• sanitizers: Maintaining the recommended residual level of an eP A
registered sanitizer at all times will decrease the occurrence of unsafe
bacteria and viruses in your spa water. The recommended Free
Available chlorine (F Ac), the amount of available chlorine sanitizer,
is 3.0-5.0 ppm. A low FAc can allow bacteria and viruses to grow
rapidly in the warm water, and a high FAc can cause discomfort
to the user’s eyes, lungs, and skin. each sanitizer carries its own
instructions regarding how much to use and when to add it to the spa
water. consult your dealer for their recommendations and instructions
on proper sanitizing of the spa.

BuIldINg A SANITIZeR RouTINe
during the first month of ownership, measure the sanitizer residual
daily in order to establish a baseline of sanitizer needed vs. spa usage.
Sanitizer needed is the amount of Free A vailable chlorine needed to
accommodate the number of users and their combined usage time. For
example, two spa users for twenty minutes every day creates regular
demand on the sanitizer that is used to determine how much sanitizer
to add in order to maintain the proper residual. If the usage pattern
increases dramatically with invited guests, the amount and frequency of
sanitizer required increases dramatically .

program. Increasing chlorine to 5 ppm for 24-48 hours removes
excess waste and chloramines from the water. Sodium dichlor is 6x
stronger than MPS and may be a more appropriate for those users that
experience heavy bather load conditions. operate all jets and leave

the water. It is important to follow the recommended application and
maintenance programs outlined for each product’s use. If the spa is
being used over an extended period of time, such as a whole afternoon
or evening, additional sanitizer will be needed.
Required: Weekly Super chlorinate/Shock the spa to reactivate the
silver ion cartridge, allow the release of silver ions, and quickly destroy
any remaining contaminants. Without this weekly shock treatment, the
silver ion cartridge may stop releasing silver ions into the water.
ImporTanT: use only dichlor sanitizer. Silver is not compatible with

VACATION wATER CARE
INSTRUCTIONS
If you plan to be away from home, follow these instructions to ensure
that the water quality of your spa is maintained:
SHoRT TIMe PeRIodS (3-5 dAyS):
1. Adjust the pH by following the instructions outlined in the Water Quality
and Maintenance section.
2. Sanitize the water by following the shock procedures also listed in the
Water Quality and Maintenance section.
3. lock your cover in place using the coverlocks.
4. upon your return, sanitize the water by following the shock
procedures, and balance the pH.
5. If Ace is installed, please refer to Tips section, vacation or limited use
in the Ace owner's Manual.
loNg TIMe PeRIodS (5-14 dAyS):
prior to leaving:
1. At least one day before you leave, set the temperature to its lowest
level. This setting should represent an approximate water temperature
of 80°F (27°c)
ImporTanT: Spa water oxidizers such as sodium dichlor (chlorine)
maintain their level of effectiveness substantially longer in warm water
80°F
(27°c)
than in hot water 101°F to 104°F (38°c - 40°c).
2. Adjust the pH as required. Sanitize the water by following the shock
procedures.
upon your return:
3. Sanitize the water by following the shock procedures. Return the set
temperature to its original setting. The spa water will be safe for you to
use once the Free A vailable chlorine residual level has dropped below
5.0 ppm.
ImporTanT: If you will not be using your spa for an extended period
of time (in excess of 14 days) and an outside maintenance service
(or neighbor) is not available to assist with the water maintenance,
draining or winterizing of the spa is recommended. Spas equipped
with our FreshWater® III ozone system can extend this to 4 weeks.
The FreshWater® III ozone system does not guard against possible
freezing damage, however.
SuPPleMeNTAl WATeR MAINTeNANce
Proper water sanitation and mineral balance (pH control) are absolutely
essential for a complete spa water maintenance program. Here are two
other popular water additives that are optional:
mineral deposit Inhibitors
As water evaporates from your spa and new water is added, the
amount of dissolved minerals will increase. (Minimize evaporation
by keeping the cover on the spa whenever possible.) The spa water
may eventually become “hard” (calcium Hardness too high) enough
to damage the heater by calcifying its surface. Proper pH control can
minimize this.
Normal soap build-up will require water replacement regularly enough
that mineral deposits normally are not a problem.
occasionally , high iron or copper content in the water may produce
green or brown stains on the spa. A stain and scale inhibitor may help
to reduce these metals.
ImporTanT: Well water may contain high concentrations of minerals.
The use of a low water volume, extra-fine pore water filter (in-line prefilter such as the clean Screen® pre-filter) will help to remove many of
the larger particles during the filling of the spa. In-line pre-filters can be
purchased at your local Hot Spring
foam Inhibitors
Spa water requires changing due to the buildup of soap in the water.
Typically, soap will cause the spa water to foam when the jets are used.
Soap is introduced into the spa water from two sources: users’ bodies,
which retain a soap residual after showering, and swimming apparel,
which retains soap after washing.
Foam inhibitors can suppress foam, but cannot remove soap from the
water. Soap is very dif ficult to remove from the water because soap is
not oxidized by any chemical added to the spa. only ozone can oxidize
soap.

eventually the soap build-up in the water will be concentrated,
resulting in an unclean feeling on the bather’s skin, which is impossible
to remedy . When this occurs, it’s time to drain and refill the spa.
depending on the soap input, the water should last about four months
before needing to be drained.
wATER TERMINOlOgY
The following chemical terms are used in this Water Quality and
Maintenance section. understanding their meaning will help you to
better understand the water maintenance process.
bromamines: compounds formed when bromine combines with
nitrogen from body oils, urine, perspiration, etc. unlike chloramines,
bromamines have no pungent odor, and are ef fective sanitizers.
bromine: A halogen sanitizer (in the same chemical family as chlorine).
Bromine is commonly used in stick, tablet, or granular form.
Calcium Hardness: The amount of dissolved calcium in the spa water .
This should be approximately 50 -150 ppm (Ace: 25 – 75 ppm). High
levels of calcium can cause cloudy water and scaling. low levels can
cause harm to the spa equipment.
Chloramines: compounds formed when chlorine combines with
nitrogen from body oils, urine, perspiration, etc. chloramines can cause
eye irritation as well as having a strong odor.
chloramines are weaker, slower sanitizers.
Chlorine: An ef ficient sanitizing chemical for spas. Watkins
Manufacturing corporation recommends the use of sodium dichlor-type
granulated chlorine. This type is preferred because it is totally soluble
and nearly pH neutral.
Chlorine (or bromine) residual: The amount of chlorine or bromine
remaining after chlorine or bromine demand has been satisfied. The
residual is, therefore,
to kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal and plastic spa parts,
usually caused by chemical action. generally , corrosion is caused by
low pH or by
the recommended ranges.
Halogen: Any one of these five elements: fluorine, chlorine, bromine,
iodine, and astatine.
mps: Monopersulfate is the non-chlorine oxidizer used with the
FreshWaterAg
nitric acid: The formulation of nitric acid, a highly corrosive chemical,
the amount of sanitizer which is chemically available
water with levels of TA, cH, pH or sanitizer which are outside
®
silver ion purification system. Not a sanitizer.
+
unlike bromamines,
is a byproduct of the ozone generating process. Nitric acid is produced
in very small quantities and is readily dissolved in the water stream with
ozone.
oxidizer: The use of an oxidizing chemical is to prevent the buildup
of contaminants, maximize sanitizer efficiency, minimize combined
chlorine and improve water clarity . See MPS and ozone.
ozone: ozone is a powerful oxidizing agent which is produced in
nature and artificially by man. ozone forms no byproducts, oxidizes
chloramines, and will not alter the water’s pH.
pH: The measure of the spa water’s acidity and alkalinity. The
recommended pH for the spa water is 7.2 to 7.6. Below 7.0 (considered
neutral), the spa water is too acidic and can damage the heating
system. Above 7.8, the water is too
water, and scale formation on the shell and heater.
ppm: The abbreviation of “parts per million”, the standard measurement
of chemical concentration in water. Identical to mg/l (milligrams per
liter).
reagent: A chemical material in liquid, powder, or tablet form for use in
chemical testing.
sanitizer: Sanitizers are added and maintained at recommended
residuals to protect bathers against pathogenic organisms which can
cause disease and infection in spa water.
scale: Rough calcium-bearing deposits that can coat spa surfaces,
heaters, plumbing lines, and clog filters. generally , scaling is caused by
mineral content combined with high pH. Additionally, scale forms more
readily at higher water temperatures.
super-Chlorination: Also known as “shock treatment.” Superchlorination is a process of adding significant doses of a quick
dissolving sanitizer (“dichlor” is recommended) to oxidize non-filterable
organic waste and to remove chloramines and bromamines.
T otal alkalinity (Ta): The amount of bicarbonates, carbonates, and
hydroxides present in spa water. Proper total alkalinity is important for
pH control. If the TA is too high, the pH is difficult to adjust. If the TA is
too low, the pH will be dif ficult
range of TA in spa water is 40 to 120 ppm.
