IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
1. DANGER - RISK OF ACCIDENTAL DROWNING.
Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents, ensure that
children cannot use this spa unless they are under adult
supervision at all times.
2. WARNING - To reduce the risk of injury:
A. A bonding lug has been provided on the outside of the
Control Module electrical control box. This lug permits the
connection of No. 6 AWG solid copper bonding conductor
between the Control Module and all other electrical equipment and exposed metal in the vicinity, as may be needed to comply with local regulations.
B. The suction fittings in this spa are sized to match the
specific water flow created by the pump. Should the need
arise to replace the drain-suction fittings or the pump, be
sure that the flow rates are compatible. Never replace a
suction fitting with one rated less than the flow rate
marked on the original suction fitting. Never remove, or
alter in any way, the covers on the drain-suction fittings in
the spa. Never operate the spa if the covers on the drainsuction fitting are broken or missing.
C. To eliminate the risk of electr ical shock install the spa
at least 5 feet (1.5m) from all metal surfaces. (A spa may
be installed within 5 feet of metal surfaces if each metal
surface is permanently connected by a minimum No. 6
AWG solid copper conductor attached to the wire connector on the terminal box that is provided for this purpose.
D. Do not permit any electrical appliances such as a light,
telephone, radio or television within 5 feet (1.5m) of the
spa.
E. The spa must only be hard wired to a supply circuit
that is protected by a ground fault circuit interrupter
(GFCI). Such a GFCI is required by most building codes,
should be provided by the installer and must be tested
before each use. Consult GFCI manufacturers instructions for correct testing and operation.
F.
The water in a spa should never exceed 40 degrees C
(1040F).
Water temperatures between 1000F and 1040F
are considered safe for a healthy adult. Lower water temperatures are recommended for extended use (exceeding
10-15 minutes) and for young children.
G. Since excessive water temperatures have a high
potential for causing fetal damage during the early months
of pregnancy, pregnant or possibly pregnant women
should limit spa temperatures to 100
0
F.
H. Before entering the spa, the user should measure the
water temperature with an accurate thermometer since
the tolerance of water temperature regulating devices ma y
vary as much as ± 5 degrees.
I. The use of alcohol, drugs, or medication before or during spa use may lead to unconsciousness with the possibility of drowning.
J. Persons suffering from obesity or with a medical history of hear t disease, low or high blood pressure, circulatory system problems or diabetes should consult a physician before using a spa.
K. Persons using medication should consult a physician
before using a spa since some medications may induce
drowsiness while other medications may affect heart rate,
blood pressure and circulation.
L. Because occasional users of the spa may not be
aware of all the potential risks associated with spa usage,
they should be made aware of these important safety
instructions.
M. The electrical supply for this product must include a
suitably rated switch or circuit breaker to open all
ungrounded supply conductors to comply with the
National Electrical Codes. The disconnection means
must be within sight and readily accessible to the spa
occupants but installed at least 5 feet (1.5m) from the spa
water. (For permanently connected units not provided
with an integral disconnecting means).
N. All units must be installed to provide drainage of compartment for electrical components.
O. Be sure that water always flows freely from the
hydrotherapy jets within the spa. Any blockage or restriction of this water flow by persons or objects may damage
system components, create an electrical shock hazard,
and/or cause water damage to the surrounding area.
P. To avoid damage to the pump and heater, the spa must
never be operated unless the spa is filled with water.

SET UP AND INSTALLATION
30 INCHES MINIMUM
EQUIPMENT ACCESS
AREA
EQUIPMENT COMPARTMENT ACCESS
When considering an installation site, always allow for a
minimum access space of 30 inches in front of the equipment compartment of the spa. This provides adequate
clearance for future service if necessary.
If accessory items will be installed on or around the spa
(gazebos, steps or planters), allow for additional space
around the spa’s perimeter.
Please note: Some cities and counties may require
a permit for installation of electrical circuits or the
construction of exterior structures (decks and gazebos). In addition, some counties may require permits for the installation of a portable spa. Check
your local codes for compliance.
SITE SELECTION
In order for your spa to function properly, it must be placed
on a SMOOTH, LEVEL, SELF-DRAINING SURFACE.
Concrete sloped at 1 inch per 10 feet is preferred so that
rain water and water spillover will run off and not puddle
underneath the spa (water under the spa for long periods of time may cause the wood to deteriorate). Other
options are brick, stepping stone or blocks.
It is important to note that soft surfaces, even
when stepping stones are used to evenly distribute the weight of the spa, will have a tendency to
settle, thus resulting in an unleveled spa.
INSTALLATION ON A WOOD DECK - Wood decking
requires that the deck must be constructed to support at least 80 pounds per square foot. Individual
spa weight per square foot will vary. Refer to a
licensed contractor for proper structural support.
Refer to the SPA SPECIFICATIONS table on the
back cover for spa dry weight and spa weight
with water.
Please Note: Placing the spa on grass or dirt may
increase the amount of debris which is inadvertently brought into the spa water and may cause harm
to your equipment as well as the spa surface, and is
not covered under warranty.
Slope 1 inch per 10 ft.

START-UP INSTRUCTIONS
Once the spa is placed on a proper foundation and connected to the appropriate electrical service, the spa may
be filled and made ready for use. For best results, read
each step in its entirety before proceeding with that step.
1. PREPARE SPA FOR FILLING
• Clear all debris from the spa.
• Although the spa shell has been polished at the factory, you may want to treat it with a specially formulated spa cleaner and wax available from your dealer
prior to filling it for the first time.
• Before filling your spa for the first time, refer to the
“EQUIPMENT COMPARTMENT” illustration on page 11 and
perform the following procedures to ensure proper operation:
• Remove the equipment compartment door.
• Check all pump and heater unions to ensure that
they are hand-tight.
• Check that all knife valv es are in the open position.
• Install pump drain plugs, if necessary.
2. FILL THE SPA
•Remove the skimmer basket and weir - see page 12.
•Inser t the end of a garden hose into the filter canister
and begin filling the spa.
•Stop filling when the water level is approximately one
inch above the highest jet.
•Reinstall the skimmer basket and weir.
3.TURN ON POWER
Turn on power to the spa at the home’s circuit breaker,
Ground Fault Circuit Interrupter (GFCI) and any other
switching devices installed by your electrician. When
power is on, the spa’s LCD screen will display information.
4. ACTIVATE JETS
• Set all air controls to the “Max” position to help you see
which jets are being activated. See illustration on page 6.
• Press the “Hydro Jets 1” touch pad on the control
panel twice to turn on the high speed of the dualspeed pump - see “SPA SIDE CONTROLS” illustration
on page 8.
• You should be able to feel a steady stream of water
from at least some of the jets. If not, refer to the
instructions for priming the pump in the SPA TROUBLESHOOTING section in the back of this manual.
• Press “Hydro Jets 1” again to turn off, then press
“Hydro Jets 2” to turn on the single-speed pump. Once
a steady flow of water is detected from some of the jets,
press this touch pad once more.
5. ADD START-UP CHEMICALS
Add the spa water chemicals as directed by your Caldera
dealer, b y the instructions contained in your spa chemical
kit or in the section titled “BALANCING THE SPA WATER”
on page 15.
6. SET TEMPERATURE
Your spa has been pre-set to automatically achieve a
water temperature of 100
0
F, which is the temperature typically preferred for comf ortable spa enjo yment. If you prefer a different temperature, press either the or
touch pad to display the temperature which has
been set. Then, each time either of these pads is pressed
again (within five seconds), the set temperature will
increase or decrease depending on which pad is
pressed.
• The maximum temperature for which the spa can be
set is 1040F and the minimum is 800F.
7. SET SPA TO HEAT
• Make certain the controls are set to operate in the
“STANDARD” operating mode. That is, if the LCD
shows “ECON” flashing alternately with the water temperature, press the touch pad to switch to
“STANDARD”mode. This allows the heater to run continuously until the set temperature is achieved. (See
“STANDARD OR ECONOMY MODE” on page 9.)
• The time required for initial heat-up will vary depending on the temperature of the fill water and the size of
the spa. You may expect a temperature rise of approximately 4 to 6 degrees per hour for larger spas and
about 8 to 10 degrees per hour for small spas.
DANGER. RISK OF INJURY. Always check the water
temperature carefully before entering the spa.
NOTE: Never fill your spa with water from a water
softener. Its corrosive effects will damage your spa’s
components.
IMPORTANT - Do not activate power until the spa
is filled. To avoid damage to the spa’s equipment,
the pumps must never be operated unless the spa
is filled with water.

(During winter months, the pumps’ drain plugs are removed
to prevent possible freeze damage during shipping and
storage. If this is the case with your spa, there will be a
notice to this efffect taped to the front of the spa’s control
box and the drain plugs will be in the plastic bag that
includes the owner’s manual.)
(Clear, plastic tubing has been factory-installed around the
shaft of each of these valves to keep them from inadver-
tently closing. This step is a precautionary measure to
ensure that these valves have not closed during shipping.)

9. INSTALL THE SPA COVER
• Place the cover squarely on the spa.
• Position the tie-down locks included with your cover
on the side of the spa so that they are easily reached
by the cover tie-down straps. Allow for about 1/2” to
3/4” slack in the straps to make it easy to insert straps
into locks and to compensate for vinyl shrinkage in
cold weather.
• Attach the locks with the screws provided and insert
the cover tie-down straps into the locks.
Keeping the cover in place any time the spa is not in
use will reduce the amount of time the heater operates, thereby minimizing operating costs.
DANGER. RISK OF INJURY.
• Never leave a spa uncovered or unattended.
• Never leave a spa cover unlocked.
• Do not stand, sit or lie on the cover.

CUSTOMIZING YOUR MASSAGE
Page 7
Your Caldera spa offers numerous ways for you to customize your massage experience. Experimentation is the
best way to find what feels best to you. Tr y sitting in different seats, adjusting the Power Diverters, air controls
and jet nozzles and turning each pump on or off.
POWER DIVERTERS
One Pow er Diverter is standard on your spa, another is optional equipment. These allow you to direct the flow of water from
the pumps to various combinations of jets.
The functions of these Pow er Div erters can best be learned by
experimentation as follows:
1. Set all air controls to the “MAX” position.
2. Turn on the high speed of both pumps.
3. Note the labels on the Power Diver ters and turn the
handles and see which groups of jets are affected.
(Note that you can adjust the Power Diverters to any
position between the two possible extremes to achieve
the jet pressure that feels best to you.)
AIR CONTROLS
Each jet system has its own air control. These allow you
to change the power of the jets by regulating the amount
of air that is mixed with the water coming out of the jets.
HYDRO JETS
Magna Jets - These jets allow you to re-direct the jet stream by
changing the position of the nozzle.
MagnaSsage Jets - These jets provide a rotating massage pattern.
The nozzles in the Magna jets and the MagnaSsage jets
are interchangeable. To remove a MagnaSsage rotating
nozzle, simply grasp it and pull straight out. To install,
align and push straight in. the nozzle will snap into place.
To remove or install a standard Magna jet nozzle, rotate
the tabs on either side of the nozzle. Additional
MagnaSsage rotating nozzles and dual-port nozzles are
available from your Caldera dealer.
Both the Magna and MagnaSsage jets allow you to regulate the force of the massage. Rotate the fascia ring
clockwise to reduce the force or counter-clockwise to
increase the force. Notice that tur ing off the flow to some
jets increases the flow to the other jets. To avoid damage
to your spa’s plumbing and components, do not turn off
more than half of these jets at the same time.
Euro and Euro-Pulse Jets
- The small euro jets deliv er a direct,
precision massage. Many of these jets feature a special insert
that creates a soft, pulsating, rotary massage. The roto jet cap
assemblies may be removed if you want a more powerful,
direct massage in a particular location. To do this, gently pry
around the outside edge of the cap assembly with a table knif e,
screwdriver or similar tool. If you desire, you may install a roto
jet cap removed from one jet onto a standard euro jet simply
by snapping the assembly into place. You may purchase additional roto jet assemblies from your Caldera dealer.
AIR JETS
The Air jet system consists of a 1 HP Air pump and 10 Air
jets. At the beginning of each skim/filter cycle, the Air jets
will operate for 30 seconds to clean out the air channel.
TIP: Turn both pumps on high speed and position the
Power Diver ters to “Combo”. Then experiment with
each of the air controls to see their effect.
IMPORTANT: Your spa is not designed to provide full
power to all jets when the Power Diverters are in the
“Combo” position. However , with the Power Diverter in
this position, you may increase the power to selected
jets by rotating the face of the Magna and
MagnaSsage jets to close the ones that are not in use.
Position 1 - The full
flow is directed to one
series of jets.
Position 2 - The flow
is shared between two
or more series of jets.
Position 3 - The full
flow is directed to a
second series of jets.

STANDARD OR ECONOMY MODE
When in ECONOMY mode, “ECON” flashes alter nately
with the water temperature on the LCD. The heater operates only
during skim/filter cycles to heat the spa water
with the following exception: Should the spa water temperature fall below 20
0
F of set temperature, the heater will
engage to heat the spa water to within 150F of the set
temperature.
In the STANDARD mode, “ECON”does not display on the
LCD. The spa’s automatic operation is exactly as
described for ECONOMY mode except that the heater
and low-speed pump activate as needed to maintain the
set temperature between filter cycles.
SKIM/FILTER CYCLES
Your spa will automatically perform two skim/filter cycles
each day. At the beginning of each cycle, the singlespeed pump and the optional air blower turn on for brief
periods to ensure complete water circulation.
The dual-speed pump’s low speed operates for the entire
duration for which the filter cycle is set. Also, the optional ozone generator operates only during these cycles.
ADJUSTING THE SKIM/FIL TER CYCLES
START TIMES The first cycle starts five to ten minutes
after the time of day when the power to your spa was last
turned on at the circuit breaker or GFCI. The second
cycle begins twelve hours later. To change the start
times, simply turn the power to the spa off and back on at
the time of day you want the first cycle to begin.
DURATION The length of each filter cycle is factory preset for two hours. You may adjust the cycle length with
this simple procedure:
1. Press either or , then press the
“HYDRO JETS 1” touch pad within three seconds. The
LCD will read “FIL” followed by a number indicating the
number of hours each cycle will last.
2. Press or to adjust. Choices are 2, 3,

MAINTENANCE
3 days a week Check water level. Make cer tain water level is 1 inch above the
highest jet.
Check and adjust Chlorine level to 1.0 to 3.0 ppm if Chlorine is
used as sanitizer.If Bromine is used, check weekly.
Once a week Test the spa water using test strips or test kit.
Adjust pH and total alkalinity - refer to pH and total alkalinity on
label of SPA UP and SPA DOWN.
Check and adjust Bromine level to 1.0 to 3.0 ppm if Bromine is
used as sanitizer.If Chlor ine is used, check three times a week.
Add 1 ounce of SPA DEFENDER per 400 gallons of water to
prevent calcium build up.
Shock treat with 2 ounces of RENEW, a non-chlorine shock.
Check and clean the skimmer basket and weir to insure proper
filter flow, remove leaves, foreign matter and debris.
Check spa cover. Make certain cover is positioned properly and
tie-down straps are fastened/locked. Be sure water and snow are
swept off or kept from accumulating or puddling on the cover.
Four to six weeks
Inspect and clean the spa filter cartridge. It is very important to
maintain your spa filter cartridge and keep it clean and free of particles
which can restrict water flow. If the filter is not cleaned on a regular
basis, the filter may clog and restrict water flow, which causes improper filtration and poor jet performance.See “FILTER CARTRIDGE
REMOVAL AND CLEANING INSTRUCTIONS” on page 12.
Two months (heavy usage)
Drain your spa. Follow the procedures outlined in “DRAINING
Five months (light usage) YOUR SPA” on page 16. Clean the spa with “Spa Multi-Purpose
Cleaner” and then polish with a silicone sealant polish. When refilling
your spa be sure to follow the “START-UP” instructions on page 5.
Six months Clean and seal your spa skirt. The spa skir t is coated with a
tinted stain for protection and to enhance the beauty of the natural
redwood. Like all wood products, prolonged exposure to the
weather and climate conditions will cause the redwood to discolor
or fade.To maintain the rich finish, apply a good quality tinted or
clear stain every six months.
Note:The stain used by Caldera is available from your Caldera
dealer.

FILTER CARTRIDGE REMOVAL AND CLEANING
INSTRUCTIONS
Turn the power to the spa off, then proceed as follows:
1. Push down slightly and turn filter basket counter-clockwise to unlock, then pull the basket and weir out.
2. Carefully pull up the filter car tridge and br ing it out of
the spa.
3. Rinse car tridge using a garden hose. Rotate and separate filter pleats while spraying water to remo v e all debris
possible. Let the filter dry and then look for calcium
deposits (scaling) or an oil film. If you find these, you will
need to deep clean your filter cartridge with a “spa filter
cleaning” solution to break down and remove mineral
deposits and oils.
4. To return basket and weir, insert and rotate clockwise to
lock into position. Then, tur n spa’s power back on.
Note: The filter cartridge should be replaced with a new
cartridge approximately every 12 months. Replacement
filter cartridges are available from your Caldera dealer.
Refer to the back of this manual to determine the appropriate size for your spa.
SPA LIGHT COLORED LENS INSTALLATION
Colored lenses are included with the spa light. To install
or remove lens, push ON or pull OFF of the spa light.
SPA LIGHT BULB REPLACEMENT
1. Turn OFF the power to the spa.
2. Remove the equipment compartment access door.
3. Locate the rear of the spa light (see “EQUIPMENT
LOCATION” on page 11).
4. To remove the bulb, turn it counter-clockwise 1/4 turn,
and remove the bulb from the socket.
5. Replace the bulb by reversing the above steps.
CAUTION: The replacement bulb must be the same rat-
ing as the factory installed bulb (replacement part number
37-0101 Fk2, package of two; or standard automotive
type #912).
POWER DIVERTER MAINTENANCE
If your spa’s Power Diverters become difficult to turn, it is
likely that sand or grit has become lodged inside the valve
body. It is very important that this debris is removed as
soon as possible to avoid damage to the v alv e . To accomplish this, follow this procedure:
1. Turn off power to the spa.
2. Remove the Power Diverter’s handle by pulling
upward while rocking it back and for th.
3. Unscrew the cap ring.
4. Remove the valve body by pulling it upward.

SPA COVER CARE
CLEANING AND VINYL CARE Keep the cover clean. As
often as is necessary wash with mild soap and rinse with
clean potable water. DO NOT USE SOLVENTS, PETROLE-
UM PRODUCTS, ABRASIVE CLEANERS OR STRONG
DETERGENTS. All vinyls contain plasticizers which migrate
out and escape naturally over time. Sun and cold speed up
this process. Applications of vinyl cleaner and conditioner,
when used according to the manufacturers instructions, may
retard this type of deterioration. DO NOT USE PRODUCTS
THAT CONTAIN SILICONE OR ALCOHOL.
CHEMICALS The vinyl and thread are marine treated but
will deteriorate quicker when exposed to high le v els of chlorine, bromine, ozone or other active chemicals. At the time
chemicals are added, remove the cover completely and
place it far enough away so splashing cannot inadvertently
reach the cover. Chemicals should be added frequently at
low levels instead of infrequently at high levels.
CARE OF SEWING HOLES AND THREAD The sewing
holes and thread are the greatest potential weakness in a
cover. Vinyl is a soft, leather-like material which the thread
can cut if the cover is roughly handled. This is especially
true when the vinyl has been exposed to hot sun. The handles, tie-downs and hinge are double reinforced with thick,
vinyl coated, rip-stop polyester webbing. However, mistreatment by sudden jerking motions can damage them.
Stretching or pulling one half against the other may rip the
cover at the thread holes. To prevent damage, an y handling
of the cover should be done in a gentle manner.
Note: Fading and discoloration will occur naturally with
extended exposure to the sun.
NON-OPERATION IN COLD CLIMATE
If the spa is to be left unused for an extended per iod of time in
areas where freezing temperatures DO NOT OCCUR, it may be
desirable to switch the spa to ECONOMY mode . When in ECONOMY mode, the spa water temperature is maintained within 20
0
F
of the set temperature.The automatic filter cycles, along with occasional chemical treatments, will keep the spa water clean and
sparkling. When preparing the spa for use, check the water chemistry to assure correct chlorine or bromine and pH levels.
You can keep the water in the spa during the time of year
when freezing at the spa location may occur. When the spa
water temperature is 200F lower than the set temperature, the
pumps and heater will be activated automatically to circulate
the water.The LCD will display the “COOL” message.
WINTERIZING Y OUR SP A
If you wish to leave y our spa empty and it is located where
freezing temperatures occur, f ollo w steps 1 thru 5 outlined
in “DRAINING YOUR SP A” on page 14 then complete the
following steps:
1. If your spa is equipped with the optional Air pump, refer
to “EQUIPMENT LOCATION” page 11 and identify its
location. If you do not have this option proceed to step #4.
2. Remove the screws securing the spa side panel and
remove panel (left hand side of spa when facing the spaside control - not the equipment compartment door).
3. Attach a shop vacuum hose to the air intake of the Air
pump, then operate the shop vacuum (in blow mode) for
a few seconds until all water has been removed from the
air jets and air channel.
NOTE: Make certain all power to the spa is OFF before you continue.
4. It will be necessar y to remove all water from the interior plumbing. Refer to the illustration on page 6 to locate
the drain/suction fittings. Remove the screws securing the
drain/suction covers, then remove the suction cover by
turning counter-clockwise.
CAUTION must be used with this approach. In the event of electrical
power interruption, regardless of the cause, the heater and pump will
stop operating and freeze protection will be lost, possibly resulting in
freeze damage to the spa, spa plumbing and/or Control Module.

2. Remove the equipment compartment
access door.
3. Locate the end of the drain hose and lift
it above the water level. (Requires clipping plastic tie the
first time.)
4. Unscrew and remove the drain cap.
5. Attach drain hose to a garden hose and
direct to an appropriate draining area,
keeping the hose below the water line.
6.
After your spa is empty, clean the
shell and filter cartridge. See “IMPORTANT MAINTENANCE PROCEDURES”
on page 10.
7. After cleaning, remove garden hose,
replace drain cap and put drain hose back
in equipment compartment.
8. F ollo w the “START-UP INSTRUCTIONS”
on page 5 to refill your spa.
5. Follow the instructions on page 12 to remove the floating weir, bask et and filter cartridge. Insert a shop vacuum
hose into the suction line located in the bottom of the filter
compartment (operate in the blow mode). If the vacuum
hose does not fit tight into the opening, air will escape. It
might be necessary to wrap a rag around the vacuum
hose to make an air-tight seal.
6. With the vacuum blowing into the opening of the filter
compartment, note that air escapes through one of the
suction openings in the footwell. Close this suction opening by installing a 1 1/2” NPT “freeze plug” (available from
a hardware store). Position all Power Diverters to
“Combo” and operate the shop vacuum in blow mode to
blow all of the water out of the jet lines supplied by the
dual-speed pump.
7. Note that there are two other suction openings in the
sides of the footwell. Remove the freeze plug used in the
previous step and install it in one of these openings.
Insert the vacuum hose into the other suction opening and
blow the water out of the jet lines supplied by the singlespeed pump.
8. Remove the freeze plug, replace the suction covers and
reinstall the screws to secure the suction covers.
9. Use a wrench to remove the pump drain plugs located
on the front of the pump housings. Allow all water to drain
out, then replace the pump drain plugs.
NOTE: DO NOT LEAVE ANY WATER IN YOUR SPA.
WARNING: When not in use, the spa must be cov-
ered with an insulating spa cover. Damage caused
by either sun exposure or freezing is not covered
under warranty.

reaches 120 ppm. If the Alkalinity is high, it should be lowered by using Spa Down (1 oz.at a time).
5. After the Alkalinity is properly adjusted, the pH is next.
If the pH is above 7.8, use Spa Down (1 oz. at a time) to
lower it to the acceptable range. If the pH is below 7.2,
add Spa Up to bring it into the acceptable range. It is
extremely important to NEVER allow the pH of your spa
water to be under 7.0, as this can severely damage your
equipment and will void the warranty.
6. Add sanitizer, either chlorine or bromine. For chlorine:
Follow the directions on the bottle. Chlorine dissolves
rapidly; you should get a reading on the test strip within
minutes of application. For bromine: Follow the directions
on your floating brominator . It is necessary to add sodium
bromide only when the spa is being filled. Bromine tablets
erode slowly, and it may take se veral hours before you will
get a reading on the test strip. It may be necessary to
adjust the floating brominator and/or your skim/filter time.
7. To properly maintain the chemical balance of your spa,
follow the 3-day-a-week program outlined below:
1. Test the water using 3-WAY SPAWATERTEST STRIPS.
2. Adjust pH and total alkalinity - Refer to pH and total alkalinity on label of SPAUP and SPADOWN.
3. Maintain 1.0 to 3.0 ppm bromine or free chlorine.
4. Add 1 ounce of SPA DEFENDER per 400 gallons of water to
prevent calcium build up.
5. Shock treat with 2 ounces of RENEW, a non-chlorine shock,
every week as needed.

ty
The instructions below will assist you with balancing the
spa water for the first time. You will need the following
items to balance your spa water.
1. “3-Way Test Strips”.
2. “Spa Up” and “Spa Down” for pH control.
3. “Spa Defender” for calcium and scale control.
4. “Metal Gone” for breakdown of mineral deposits.
5. “Renew” for shock treatment.
6. “Bromine” or “Chlorine” for sanitizing the spa water.
Please read “WATER MAINTENANCE” on page 16 then
follow these easy steps:
1. Fill your spa until the water level is 1 inch above the
highest jet. It is NOT advisable to use softened water in
your spa, as it may be corrosive.
2. Add 1/2 pint of Spa Metal Inhibitor (Metal Gone) to
prevent iron or copper deposits from staining the finish of
your spa. If your water is known to contain high concentrations of these metals it may be necessary to add an
additional quantity of Spa Metal Inhibitor.
3. Use a 3-way spa water test strip or test kit to measure the pH and Alkalinity of your water. The following
instructions utilize test strips for testing.Immerse the test
strip in the spa water, following the instructions on the
test strip container label. Compare the test strip to the
label to determine the condition of the spa water.
Note: Many of the additives mentioned here are referred to by
brand name. If your chemicals are a different brand, ask your
Caldera dealer which additives are comparable, if necessary.
Note: The above table is an example only. Actual
spa usage will determine the amount of chemicals
required to maintain proper chemical balance.

1. Nothing required if bromine is used as sanitizer. Check
and adjust chlorine level if chlorine is used.
WATER PURIFICATION WITH OZONE (OPTION)
The Caldera Pure Water Ozone system produces ozone
to “burn out” water contaminants, bacteria and viruses
through the process of oxidation.Ozone is continually produced and distributed to the spa during the
filtration/skim/filter cycles.
Ozone does not replace traditional water sanitizing chemicals such as chlorine or bromine. A small amount of chlorine or bromine will be needed in the water in addition to
ozone. Ozone will be doing the major job of killing
microorganisms and oxidizing bather waste such as perspiration, body oil, suntan lotion, etc. The chlorine or
bromine will be providing the measurable, lasting residual
and preventing algae from growing.
DO’S AND DON’TS OF SPA WATER MAINTENANCE
DO read labels carefully and follow direction precisely.
Though chemicals protect you and your spa when used
correctly, they may be hazardous in a concentrated form.
DO add all chemicals slowly into the filter compartment
with the Hydro jets operating in high speed.
DO handle all containers with care. Store in a cool, dry, wellventilated place.
DO NOT use swimming pool chemicals in your spa.
DO NOT use household bleach (liquid sodium hypochlorine).
DO NOT use swimming pool (muriatic) acid to lower pH.
Many swimming pool water care products can cause damage to spa surfaces and equipment.
DO NOT splash pH “increase” additives on the redwood
cabinet during pH adjustment. Many pH “increase” additives will cause redwood to turn dark by pulling the tannin
(reddish color in redwood) out of the wood.
DO NOT allow anyone to be in the spa while chemicals
are being added or dissolving.
DO NOT use incorrect products such as Trichlor, which
has a very low pH (2.6), dissolves very slowly, is highly
concentrated and was designed for concrete or plaster
swimming pools. It will cause damage to your spa!
