Part #7618 Manual Revised July 04

When installing your spa and using this equipment, basic safety precautions should always be followed, to include the following:
!READ AND FOLLOW ALL INSTRUCTIONS! The following instructions are required by UL 1583 standard to be
printed as a condition of their listing this product. They contain important safety information we strongly urge you to read
and apply.
!DANGER - TO REDUCE THE RISK OF INJURY: Do not permit children to use spa unless they are closely supervised
at all times.
WARNING SIGN MUST BE POSTED
The WARNING sign (RED) above is packed with your new Hydrospa Spa. This sign must be posted in a prominent place in close
proximity to the spa installation site immediately upon completion of spa installation.
!WARNING SIGN - It is extremely important that this sign be permanently placed in clear view of any persons using the
spa. Occasional spa users may not be aware of some of the dangers hot water poses to pregnant women, small children, and
people under the influence of alcohol. If you did not receive a warning sign or your sign has become damaged, please
contact your spa dealer or manufacturer.
!DANGER - Awire connector is provided on this unit to connect a minimum No. 8 AWG (8.4mm2) solid copper conductor
between unit and any metal equipment, metal inclosures of electrical equipment, metal water pipe, or conduit, if that item is
located within 5 feet (1.5m) of the unit.
!DANGER - RISK OF ACCIDENTAL DROWNING: Extreme Caution must be exercised at all times, to prevent
unauthorized access by children. To avoid accidents, ensure that children cannot use spa unless they are supervised at all
times. Cover spa and use safety locks to prevent accidents.
!DANGER - TO REDUCE THE RISK OF INJURY: The suction fittings in the spa are sized to match the specific water
flow created by the pump/pumps. Should the need arise to replace the suction fittings or the pump/pumps, be sure that the
flow rates are compatible.
!DANGER - RISK OF ELECTRICAL SHOCK: Install at least 5 feet (1.5m) from all metal surfaces. As an alternative, a
spa may be installed within 5 feet (1.5m) of metal surfaces if each metal surface is permanently connected by a minimum
No. 8 AWG (8.4mm2) solid copper conductor to the wire connector on the terminal box that is proved for this purpose. Do
not permit any electrical appliance, such as a light, telephone, radio or television within 5 feet (1.5m) of the spa, unless
factory installed.
!Position spa to provide proper drainage of the compartment for electrical components.
!For floor recessed spas, install to permit access for servicing from above or below floor.
!NEVER USE AN EXTENSION CORD!
!Consideration should be taken for water splash out. Water can ruin wood floors and some finishes.
!DO NOT use a wall switch, ground fault circuit interrupter, circuit breaker, fuse, or plugging and unplugging the spa as a
means of turning on or off your spa for normal everyday use.
!DO NOT block access door.
!Set the spa on a firm level (flat) surface. DO NOT set spa on blocks as structural damage may occur to spa.
!00
WARNING - To reduce the risk of injury. The water in a spa should never exceed 40 C (104 F). Water temperatures
0 0 0 0
between 38 C(100 F) and 40 C (104 F) are considered safe for a healthy adult. Lower water temperatures are
recommended for young children and when spa use exceeds 10 minutes.

!Since excessive water temperatures have a high potential for causing fetal damage during early pregnancy, pregnant or
00
possible pregnant women should limit water temperatures to 38 C (100 F). Before entering a spa, the user should test the
water temperature with an accurate thermometer. The tolerances of water temperature-regulating devices vary. The use of
alcohol, drugs, or medication before or during spa use may lead to unconsciousness with the possibility of drowning.
Persons suffering from obesity, medical history or heart disease, low/high blood pressure, circulatory system problems, or
diabetes, should consult a physician before using a spa. Persons using medication should consult a physician before using a
spa because some medications induce drowsiness while others may affect heart rate, blood pressure and circulation.
HYPERTHERMIA
Prolonged immersion in hot water may induce hyperthermia. Adescription of the causes, symptoms, and effects of hyperthermia are
as follows:
Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above the normal body temperature of
00
98.6 F (37 C). The symptoms of hyperthermia include drowsiness, lethargy, and an increase in the internal temperature of the body.
The effects of hyperthermia include.
!Unawareness of impending hazard;
!Failure to perceive heat;
!Failure to recognize the need to exit spa;
!Physical inability to exit spa;
!Fetal damage in pregnant women; and
!Unconsciousness and danger of drowning.
IMPORTANT: Because of the combined weight of the spa, water and users, it is extremely important that the base upon which the
spa rests be smooth, flat, level and capable of uniformly supporting this weight, without shifting or settling, for the entire time the spa
is in place. If the spa is placed on a surface which does not meet these requirements, damage to the skirt and/or the spa shell may
result. Damage caused by improper support is not covered under warranty. It is the responsibility of the spa owner to assure the
integrity of the support at all times. It is strongly recommended that a qualified licenced contractor prepare foundation for your spa.
Manufacturer recommends a poured, reinforced concrete slab with a minimum thickness of 4 inches (10cm). Wood decking is also
acceptable provided it is constructed so that it meets the requirements outlined above. The spa must be installed in such a manner as
to provide drainage away from the spa. Placing the spa in a depression without provisions for proper drainage could allow rain,
overflow and other casual water to flood the equipment and create a wet deck. Install so as to permit access to the equipment, either
from above or below, for servicing. Make certain that there are no obstructions which would prevent removal of the cabinet side
panels and access to the jets components, especially on the side with the equipment bay doors.
Outdoor Location
In selecting the ideal outdoor location for your spa, we suggest that you take into consideration:
1. The proximity to changing area and shelter (especially in colder weather conditions).
2. The pathway to and from the spa (free of debris, dirt, leaves as not to be tracked into spa).
3. The closeness to trees and shrubbery (leaves and birds could create extra work).
4. Asheltered environment (less wind, weather exposure resulting in lowered operation and maintenance costs).
5. The overall enhancement of your environment. It is preferable not to place the spa under an unguttered roof overhang since run-off
water will shorten the life expectancy of spa cover.
Indoor Location
Be sure your spa will fit into the space you have chosen. Proper access into the home is needed to move the spa into place.
Ventilation may be needed because of the humidity from the spa. In most cases, a spa cover is sufficient. Be sure to check the load
carrying capabilities of the floor you will be installing your spa, as most homes meet the requirement of 80lbs per square foot
(manufacturer not responsible). Insure you have proper drainage in the event of a leak or water spill due to over load of spa with
people causing water damage (manufacturer not responsible. Incase of maintenance problems, leave enough room around the spa to
work. Choose proper flooring area for spa.

Spa Drain

START-UP INSTRUCTIONS
FILLING THE SPA
Clear all debris from inside the spa. At the factory your spa shell was cleaned and polished, but you may want to treat it with a
specially formulated spa cleaner available from your dealer prior to filling it for the first time.
Make sure the spa has been installed correctly, including electrical wiring connections as specified in the wiring diagram, and the spa
is level.
Do Not Over Fill. Never fill your spa with water from a water softener, or use hot water while filling. Ensure that your spa drain is
shut off. Remove your filter lid. Place your garden hose into the filter housing and begin filling with clean water see figure 5 (Page 7 ).
Continue filling spa until the water level is 3 inches above the filter housing see figure 5 (Page 7 ). Remember every person entering a
spa displaces a given volume of water, so adjust water level to number of people who will be entering spa.
If your water is extremely “hard”, it is preferable to fill half-way with hard water and the rest of the way with softened water. Or, you
may fill the entire spa with hard water if you use a special water additive available from you Hydrospa Spa dealer.
Always refill spa through one filter housing to purge any trapped air from pump intakes. Failure to do so may cause air to be trapped
in either pump #1or the circulation pumps intake creating an air lock, preventing either pump from circulating water. Ensure both
shutoff valves are fully open see figure 3 (page 6 ). Make sure filter cartridge is clean before installing. See “Cleaning the Filter” for
specific cleaning procedures (see page 11 ).

SPA CAREAND MAINTENANCE
SPA CAREAND MAINTENANCE
Filter Cleaning and Cartridge Replacement
The filter(s) in your spa should be cleaned at least every 5-6 weeks, depending on spa usage. This will ensure that the water is being
filtered properly, and there is no restriction in the filter due to dirt and grease build-up.
Cleaning the filter can be done easily using a Filter Degreaser solution and following
the directions on the bottle. Soak filter in a degreaser and power wash with a garden
hose. It is recommended to have a second filter, which can be cleaned between filter
changes. This will enable you to quickly exchange the dirty filter with a clean filter
and immediately start your spa up again. Filter Element
Care Of The Exterior
Spa Shell
Your spa shell is made of acrylic. Stains and dirt generally will not adhere to the surface. Using a soft rag or a nylon scrubber should
easily remove most dirt. Most household chemicals are harmful to your spa’s shell. See your dealer for the best product to use. The
only products which have passed the manufacturer’s test are Soft Towel and Windex. Sodium bicarbonate (baking soda) can also be
used for minor surface cleaning. Always thoroughly rinse off any spa shell cleaning agent with fresh water.
NOTES: Iron and copper in the water can stain the spa shell if allowed to go unchecked. Ask your Hydro Spa dealer about a stain
and scale inhibitor to use if your spa water has a high concentration of dissolved minerals.
The use of alcohol or any household cleaners other than those listed to clean the spa shell surface is NOT recommended. DO NOT
use any cleaning products containing abrasives or solvents since they may damage the shell surface. NEVER USE HARSH
CHEMICALS! Damage to the shell by the use of harsh chemicals in not covered under the warranty.
IMPORTANT: Some surface cleaners contain eye and skin irritants. Keep all cleaners out of the reach of children and use care when
applying.
Maintenance Free Cabinet
Hydro Spa’s consists of a rigid polymer that combines the durability of plastic with the beauty of redwood or gray looking cabinet.
Cabinet will not crack, peel, blister or delaminate. Cleaning consists of simply spraying the cabinet with a mild soap and water
solution to remove any stains and residue.
Draining Your Spa
Remove screws from cabinet panel door and set aside as shown below.
!Turn power off
!Select a safe suitable drainage capable of safely assimilating 300 plus gallons of water, which may contain both
unsanitary contaminants and chemical residue that could cause harm to plants or grass.
!Twist the drain fitting counter clockwise to open valve.
!The spa will drain by gravity flow.
!Close the disconnect drain fitting clockwise to close valve.
!Refill the spa through the filter shown on figure 5 (Page 7) before restoring power.
To clean and condition the vinyl cover:
!Remove the cover from the spa and gently lean it up against a wall or fence.
!Using a garden hose, spray the cover to loosen and rinse away any dirt or debris.
!Using a sponge and/or a soft bristle brush, and using a very mild soap solution (one teaspoon dishwashing liquid with
two gallons of water), or baking soda (sodium bicarbonate), scrub the vinyl top in a circular motion. Do not let the vinyl
dry with a soap film on it before it can be rinsed clean.
!Scrub the cover’s perimeter and side flaps. Rinse clean with water.
!Rinse off the underside of the cover with water only (use no soap), and wipe it clean with a dry rag.
!To condition the cover after cleaning, apply a thin film of vinyl cleaner to the surface and buff to a high luster.
Care Of Spa Cover

11
!DO NOT walk or stand on top of cover (unless you own a “walk-on-cover”.
!DO remove snow buildup to avoid breakage of the foam core from the additional weight of the snow.
!DO lock cover locking straps to secure the cover when the spa is not in use.
!DO NOT drag or lift the spa cover using either the flaps, or the cover lock straps.

WATER QUALITYAND MAINTENANCE
Your WaterIn Your Spa
The quality of your water in your spa is important to keeping it clean. Your dealer can guide you through the process of achieving and
maintaining perfect water in your spa in your given local conditions. Your program will vary depending on your water’s mineral
content, and how often you use your spa, and the amount of people using it.
Here are our suggested step-by-step procedures:
General Information - The three fundamental areas of water maintenance.
* Water Filtration * Chemical Balance/pH Control * Water Sanitation
The water’s chemical balance and pH control are also your responsibility. You will have to add chemicals to maintain proper levels of
TotalAlkalinity (TA), Calcium Hardness (CH) and pH. Proper water balance and pH control will minimize scale buildup and
corrosion of metals, extend the life of the spa, and allow the sanitizer to work at maximum efficiency.
Methods For Testing Spa Water
Accurate water testing and analysis are an important part of effectively maintaining your spa water. You must have the ability to test
for:
!Total Alkalinity (TA)
!pH
!Calcium Hardness (CH)
!Sanitizer
Two types of testing methods are recognized and recommended:
!Reagent Test Kitis a method which provides a high level of accuracy. They come in either liquid or tablet form.
!Test Strips are a convenient testing method used by many spa owners. Keep in mind that test strips are susceptible to
heat and moisture.
Basic Chemical Safety
When using chemicals, always read the labels carefully and follow directions. Though chemicals protect you and your spa when used
correctly, they can be hazardous in concentrated form. Observe the following guidelines:
!Allow only a responsible person to handle spa chemicals KEEP OUT OFTHE 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 each 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. Rinse off with fresh water if spilled.
!Never smoke around chemicals. Some of the fumes can be highly flammable.
!Don’t store chemicals in the spa equipment compartment.
Adding Spa Chemicals:
!Fold back the spa cover. Carefully remove and set aside the filter lid.
!Push the JETS1 button to turn on the pump.
!Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to
splash chemicals on your hands, eyes, or on the spa shell surface or cabinet.
!Replace filter lid and run spa for 10 minutes on high speed. Re-install spa cover.
IMPORTANT: Super Cholorination/Non-Chlorine Shock Treatment - NOTE: 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. Ahigh
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 of the spa cover.

Balancing TotalAlkalinity (TA)
!The recommended TotalAlkalinity (TA) for your spa water is 125-150 ppm.
!TotalAlkalinity is measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in
the water. TA is referred to as the water’s “pH buffer”. It’s a measure of the ability of the water to resist changes in pH
level.
!If the TAis too low, the pH level will fluctuate widely from high to low. Fluctuations in pH can cause corrosion or
scaling of spa components. Low TAcan be corrected by adding pH/Alkalinity UP (sodium hydrogen carbonate).
!If the TAis too high, the pH level will tend to be high and may be difficult to bring down. It can be lowered by adding
pH/Alkalinity down (sodium bisulfate).
!Once the TAis balanced, it normally remains stable, although the addition of more water with a high or low alkalinity
will raise or lower the TAreading of the water.
!When the TotalAlkalinity is within the recommended range, proceed.
Balancing Calcium Hardness (CH)
!The recommended Calcium Hardness (CH) level for your spa is 150-200ppm.
!Calcium Hardness is a measure of the total amount of dissolved calcium in the water. Calcium helps control the
corrosive nature of the spa’s water. That’s why calcium-low water (commonly know as “soft” water) is not
recommended. It is very corrosive to the equipment, and can cause staining of the spa shell. If the calcium level is too
low, we recommend using Calcium Increaser to bring the calcium hardness level to within the recommended range.
!If the CH is too high (commonly know as “hard” water), formation of scale on the spa’s shell surface and equipment can
result. CH can be decreased by dilution - a mixture of 75% hard and 25% soft water will be a good starting point. If soft
water is not available, or practical for you, a stain and scale control such as Scale Defense should be added to the spa
water, according to instructions on its label.
!Once the CH is balanced, it normally remains stable, although the addition of more water with a high or low calcium
content will raise or lower the CH reading of the water.
!When the Calcium Hardness is within the recommended range, proceed.
Balancing The pH
!The recommended pH level for your spa water is 7.4-7.6.
!The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those below 7 are acidic.
Maintaining the proper pH level is extremely important:
!Optimizing the effectiveness of the sanitizer.
!Maintaining water that is comfortable for the user.
!Preventing equipment deterioration.
If the spa water’s pH level is too low, the following may result:
!The sanitizer will dissipate rapidly.
!The water may become irritating to spa users.
!The spa’s equipment may corrode.
If the pH level is too low, it can be increased by adding pH/Alkalinity Up (sodium hydrogen carbonate) to the spa water.
If the pH level is too high, the following may result:
!The sanitizer is less effective.
!Scale will form on the spa shell surface and the equipment.
!The water may become cloudy.
!The filter cartridge pores may become obstructed.
If the pH is too high, it can be decreased by adding pH/Alkalinity Down (Sodium bisulfate) to the spa water.
NOTE: After adding pH/Alkalinity Up (sodium hydrogen carbonate) or pH/Alkalinity Down (sodium bisulfate), wait at least
two hours before testing the water for pH. Measurements taken too soon may not be accurate.
!It is important to check the pH on a regular basis. The pH will be affected by the bather load, the addition of new water,
the addition of various chemicals, and the type of sanitizer used.
!When the pH is within the recommended range, proceed.

Maintaining Sanitizer Level
!Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing
in the spa. At the same time, you don’t want too high a sanitizer level, or it can irritate your skin, lungs, and eyes.
!Always maintain the sanitizer level in your spa at the recommended level for each type of sanitizer.

Ozone
Hydro Spa’s Ozonation System drastically reduces the use of chemicals in the water. This also aids in maintenance requiring less
attention from harsh chemicals and less frequency with which they are used.
Replacement Of Ozone Tubing and Ozonator
Call your manufucture to provide you with maintenance service if replacement of ozonator or tubing is required. Remove door panel
screws and set door panel aside. The Ozone is setting above the Control Electrical Equipment Pack shown below or in area. The
ozonator plugs into the Control Electrical Equipment Pack. Tubing is mounted above the ozonator and has a Harford Loop as shown
below.
WATER QUALITYAND MAINTENANCE
Water Terminology
Bromamines: Compounds formed when bromine combines with nitrogen from body oils, urine, perspiration, etc. Unlike
chloramines, bromamines have no pungent odor, and are effective sanitizers.
Bromine: Ahalogen 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 150-220 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. Unlike bromamines, chloramines are weaker, slower sanitizers.
Chlorine: An efficient sanitizing chemical for spas.
Chlorine (or Bromine) Residual: The amount of chlorine or bromine remaining after chlorine or bromine demand has been satisfied.
The residual is, therefore, the amount of sanitizer which is chemically available to kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal spa parts, usually caused by chemical action. Generally, corrosion is caused by low
pH or by water with levels of TA, CH, pH or sanitizer which are outside the recommended ranges.
DPD: The preferred reagent used in test kits to measure the Free Available Chlorine.
Halogen: Any one of these five elements: fluorine, chlorine, bromine, iodine, and astatine.
MPS: Monopersulfate is the non-chlorine oxidizer used with the purification system.
Nitric Acid: The formulation of nitric acid, a highly corrosive chemical, 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.
Ozone: Ozone is a powerful oxidizing agent which is produced in nature and artificially by man. Ozone forms no byproducts of
chloramines (ozone actually oxidizes chloramines) and will not alter the water’s pH.
Pathogen: Amicroorganism such as bacterium that cause disease.
pH: The measure of the spa water’s acidity and alkalinity. The recommended pH for the spa water is 7.4 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 alkaline and can result
in cloudy water, and scale formation on the shell and heater.

Reagent: Achemical material in liquid, power, 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, scalling is
caused by mineral content combined with high pH. Additionally, scale forms more readily at higher water temperatures.
