Owner Manual

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, below which is acidic and above which is alkaline. In hot
tub water, it is ideal to keep the water between 7.2 to 7.8. 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 (scal-
ing). In addition, the ability of the sanitation agents to keep the hot tub clean is severely a!ect-
ed as the pH moves beyond the ideal range. That is why almost all hot tub water test kits con-
tain a measure for pH as well as sanitizer.
IMPORTANT: Heater and other component failure due to improperly maintained pH or Total
Alkalinity is not covered under warranty.
Other Additives
Their are many other additives are available for your spa. Some are necessary to compensate
for out-of-balance water, some aid in cosmetic water treatment and others simply alter the feel
or smell of the water. In many cases if the water chemistry gets to far o!, it is easier to drain
and refill the spa then add lots of expensive chemicals to try to fix it.
Ozonator (If Equipped)
All Futura spas are factory prepared to accommodate an ozonator. The Futura Spas Corona
Discharge Ozonator is regarded as the most advanced system on the market reducing chemical
consumption and maintaining clearer, cleaner water. The Corona Discharge Ozonator runs
when ever the spa is in the filtration cycle. Continuous use of an ozonator can dramatically re-
duce sanitizer consumption.
The ozonator will automatically activate when the spa enters its filtration mode or when the
spa is heating. When the ozonator is active you will be able to notice a very faint blue light
coming from the clear tube attached to the ozonator. The ozonator has a finite life and will
need to be replaced after several years.
Draining & Winterizing Your Spa
After a certain time, you may find that the addition of chemicals will not clarify or eliminate
odors in the spa. This is an indication that the water needs to be drained and replaced. Gener-
ally, depending upon bather load and water chemistry maintenance, this may need done every 3
months. With the use of ozone as the sanitizing agent, it is found that the water needs changed
less frequently. Draining of a Futura Spa requires creating a siphon with your garden hose.
1. Turn o! all power to the spa.
2. Hook-up garden hose to an exterior spigot on the house.
3. Place other end of garden hose into the bottom of the spa.
4. Turn on the garden hose allowing water to fill into the spa.
5. After several minutes, after all the air has been pushed out of the garden hose turn the
water o! and disconnect the hose from the house spigot.
6. Keep the garden hose below the spa and a siphon will start
Once the spa is empty, clean the interior surfaces with a product designed for cleaning the
acrylic su$ce and a soft towel. Do not use soaps or detergents as they will cause the fresh spa
water to foam. Refill and restart the spa.
