20 VITA SPA DUET
Sanitizing with Ozone
Spas vary in size, as well as frequency and
conditions of use. For this reason you will need
to establish your sanitizing program based
upon your own personal use. When using
ozone, you should start by balancing your
water chemistry as you normally would. The
Duet model spa should run and be ozonated
a minimum of 4 hours per day. If your spa is
heavily used, this time should be increased.
Your spa produces ozone during the  ltration
and heating cycles. The amount of a residual
sanitizer (chlorine or bromine) that you
maintain in the water will also vary depending
on use. It is recommended that you maintain a
residual of 3.0-5.0 ppm. Periodically, and after
periods of heavy use, it is necessary to ‘shock’
your spa with large amounts of sanitizer.
NOTE: The ozonator is programed to turn
on anytime the low speed pump is on.
NOTE: Extra  ltration can be provided by
manually starting a clean-up cycle. Turn
Pump 1 on in low speed. The pump will
operate for 2 hours and then automatically
turn o .
Specialty Chemicals
While ozone may signi cantly reduce the
usage of specialty chemicals it is not a
substitute for these chemicals. All chemicals
should continue to be monitored, especially
during periods of heavy usage and when
changing or replenishing the spa water.
Draining your Spa
NOTE: Always turn the circuit breaker o
when you drain your spa. Do not turn the
spa heater back on until you have full  ow
coming from the jets for several minutes..
Changing your spa water, cleaning the spa
surface and  lter are necessary because high
concentrations of impurities caused by water
evaporation, body oils, perfumes, and other
contaminants may accumulate in the spa that
cannot be  ltered out.
NOTE: It is advisable to drain your spa and
re ll it with fresh water every six to eight
weeks or more often, depending on the
amount of use.
All spas are equipped with both external and
internal drains. The external drain is used for
draining the spa. The internal drain(s) are used
to remove water from internal hoses when
winterizing your spa (See pg. 21) or if the
water is severely contaminated.
NOTE: Use a standard garden hose to direct
the water to an appropriate disposal area.
The external drain valve is located in a
compartment on the front panel. Open the
compartment, pull the valve out, remove the
outer black cap and connect a garden hose
to the  tting. Turn the ring on the back of the
valve counter-clockwise until it stops, then
pull out to open the valve. Water will begin to
 ow. When  ow stops, push in the valve, turn
ring clockwise until it stops, remove hose and
replace the cap.
The internal drain hose(s) is (are) located
behind the front access panel. Remove the
access panel screws and the access panel.
Locate the drain hose(s). For each hose drain
valve, remove the cap, attach the garden
hose, and turn the valve body 90° counter-
clockwise. Water will begin to  ow. When all
water has been evacuated, turn the valve
handle clockwise until it stops. Remove
