JETS
Use the JET pad on the bather panel or auxiliary jet
control panel. First press of the JET pad activates
pump on low-speed (and starts soak timer). Second
press of the JET pad activates pump on high-speed.
Third press of the JET pad turns jets off for all-quiet
mode. Fourth press of the JET pad turns pump back
to low-speed. If the pump is already on low (heating,
filter cycle) then the first press starts the soak timer.
After running on low- or high-speed for 15 minutes,
the pump automatically turns off (unless in heating
or filtering cycle).
SOAK TIMER AND SOAK FEATURE
The soak timer starts the first time you press a JET
pad. The LCD window displays the elapsed time (1-
30) for 55 seconds then switches to the current
water temperature for five seconds then back to the
timer. It continues to alternate for the entire 30
minutes. The timer runs for 30 minutes regardless of
other functions in use (jets, temperature, or light).
You can manually cancel the timer by pressing the
TEMP+- pad and then the LIGHT pad.

CONSTANT CLEAN WATER MANAGEMENT
WITH SMART LOGIC (Spirit, Mirage, Wish)
Factory Default Settings:
• Filter Cycle Duration: F2 (2 hours)
• Filter Cycles: 2C (twice per day)
• Smart Logic: 1H (1 hour)
These settings represent the most commonly used
settings, but your use may be different, depending
upon many variables – frequency, number of bathers,
duration, water capacity, etc. These variables affect
the quality of water and the way it should be man-
aged to achieve the most effective cleansing. Se-
lectable choices for the settings of the operation
systems allows flexibility and ensures your Marquis
spa remains easy to maintain for your particular set of
circumstances.
SOLID-STATE OZONATOR
The ozonator greatly reduces the amount of chemi-
cal sanitizer you need in the water to keep your
water clean. The ozonator functions whenever the
pump is running on low speed. You should occasion-
ally inspect your ozonator to ensure it continues to
light (see MAINTENANCE, Every Three to Four
Months). A good time to do this is when you drain and
fill your spa.
CONSTANT CLEAN FILTRATION
Your spa is preset at the factory with a default setting
to filter itself using the jet pump on low-speed for two
hours twice in a 24-hour period. These settings
represent the filter settings necessary for average
use. The timing of the first filter cycle is determined
by when the spa was initially energized. The first
cycle begins six minutes after this initial power-up.
The second filter cycle begins 12 hours after the
first cycle.
To adjust the filter settings
First press of the SETTINGS pad displays the filter
time settings (F1, F2, F4, F6). Use the TEMP+- pad to
scroll through the options. When desired selection
has been reached, press the SETTINGS pad again to
enter selection and advance to the filter cycle set-
tings (2C, 1d, 1n). For example, if you select 2C and
F2, your spa will filter two hours twice a day for a total
of four hours of filtration daily.

SMART LOGIC
Since a spa is always covered when not in use, it
stays fairly free of debris or outside contamination.
Contamination to a spa’s water occurs during usage,
so filtering immediately after usage is the most
effective time to clean the spa water. Your spa is
preset at the factory with a default setting to filter for
one hour (1H) every time your spa is used. This
filtration cycle begins 30 minutes after the spa light or
jet pump has been deactivated. The pump runs on
low-speed to filter the water for the cycle’s duration.

HEAT LIGHT
The HEAT ON light illuminates when the heater is on.
The pump circulates on low-speed whenever the
thermostat calls for heat.
HEAT MODE
Your spa comes preset in the standard heat mode.
For most applications, the standard mode should be
used. If you are in a warm weather climate and the
spa does not require as much heat, the economy
mode may work best. For a vacation home or for
very infrequent use, the sleep mode provides filtra-
tion and circulation with lower energy demand. In
economy mode your spa heats only during the filter
cycle. In sleep mode your spa will maintain a water
temperature that is 20°F (7°C) below the set tem-
perature. This ensures your spa will be ready to use
more quickly (allow about one hour per one degree F
for heating your spa’s water) when increasing the
temperature to the desired level.
The spa’s heat mode can be adjusted to one of
three different settings:
Standard Mode
The spa water heats to the temperature as set at the
bather’s panel. In this mode the filtration pump turns
on for two minutes every half-hour to “poll” or check
the water. If heat is needed the unit heats to the set
temperature. The LCD window steadily displays the
actual temperature in this mode.
Economy Mode
In this mode the spa only heats to the set tempera-
ture during a filter cycle. The LCD window displays
“Ecn” alternately flashing with the actual temperature
when the spa is up to temperature and “Ecn” steadily
when the spa’s water temperature is below the set
temperature.
Sleep Mode
Your spa will maintain a water temperature that is 20°F
(7°C) below the set temperature. Heater functions
only during a filter cycle. The LCD window displays
“SLP” flashing alternately with the actual temperature
when the spa is up to set temperature and displays
“SLP” steadily when below set temperature.

IMPORTANT CHEMICAL SAFETY PROCEDURES
1 Always keep chemicals out of reach of children.
2. Read product labels carefully prior to use.
3. When dissolving, always add chemicals to water,
do not add water to chemicals. Some dry chemi-
cals should be dissolved prior to adding them to
the spa. Using a clean container, dip some water
from the spa. Mix until dissolved, then add to
circulating water. NOTE: Broadcasting dry chemi-
cals into the spa water may cause damage to
surrounding surfaces.
4. CAUTION: Do not add chemicals together. Add
them separately to the spa water.
5. All chemical products should be stored in a cool,
dry, well-ventilated area where the average
temperature does not exceed 90°F (32°C). Keep
storage area clean of debris such as rags, news-
paper, and combustible materials.
6. Keep chemicals away from open flame or other
heat source. Do not smoke near chemicals. If a
dry chlorine chemical fire should occur, use water
only. Do not use a dry chemical fire extinguisher to
attempt to put out the fire.
7. When adding chemicals, always keep the water
circulating in the spa with jets in a downward
circular pattern for better chemical distribution.
Add chemicals to the spa water one at a time.
Allow several minutes between any new chemical
additions using the jet action to evenly distribute
throughout the spa.
8. Wait approximately 15 minutes after adding
chemicals to retest your water for an accurate
reading. Retest your spa water before using.
9. If you have any questions or concerns about the
correct procedures for handling chemicals, please
contact your spa dealer or Marquis Spas.

MARQUIS SPAS

UNDERSTANDING WATER BALANCE
Water balance is the interrelation of factors that
determine the quality of the spa water. The effective-
ness of chemicals and other additives are dependent
on all these factors working together or “in balance”.
The primary elements to water balance are sanitizing,
monitoring pH and alkalinity levels, and oxidizing or
shocking.
Before we begin, it’s important to understand that a
spa is not just a “small swimming pool” and that the
care of a spa needs to be handled differently. In
addition to the fact that a spa is kept at a tempera-
ture of up to 104°F (40°C) and pool chemicals are
designed for cool water, the ratio of people per gallon
in a spa is also very different. Four people in a spa is
the equivalent of having 200 people in a typical
backyard pool. This increased “bather load” in-
creases the residue from soaps, perfumes, body oils,
cosmetics, and other contaminants. Always use
water treatment products designed for spa use.
Sanitizing Methods
All Marquis spas are equipped with the exclusive
Marquis Ozonator. The use of an ozonator greatly
reduces the amount of chemical sanitizer you need in
the water. Ozone works by delivering activated
oxygen gas into the spa water via an ozone injector
fitting. The ozone gas combines with contaminants to
sanitize the water. Although sometimes promoted as
a stand-alone chemical free alternative, we recom-
mend that you maintain a small residual of bromine (or
chlorine) in the water while using any ozone system.
Supplementing the water with sanitizer controls and
prevents bacteria growth. Instead of the normal 3 - 5
ppm of sanitizer recommended, you only need to
maintain a 0.5 ppm level of bromine (or chlorine) when
using an ozonator.
Only the use of ozone, bromine (or chlorine if not
using the Spa Frog® system) are recommended. Use
of other alternative sanitizer systems may void the
warranty. Important: Cal Hypo and TriChlor
compounds are not recommended for use with
a Marquis spa.
All Marquis Spas
are equipped with
our exclusive
Marquis Ozonator.
marquis care and enjoyment guide
PAGE 56
MARQUIS SPAS

Alkalinity
Alkalinity acts as a buffer to prevent the pH level from
changing as other substances are added to the water.
Proper alkalinity is directly related to the stability of the
pH. The alkalinity should be between 80 - 120 ppm.
Alkalinity levels below 80 ppm make it very difficult to
stabilize the pH level. Levels above 120 ppm may
increase pH levels and cause cloudy water, scaling,
and decreased efficiency of the sanitizer.
pH Level
The pH level measures the relative acidity and basicity
of the water. The ideal pH level is 7.2 - 7.8. When the pH
level falls below 7.2 the water can become corrosive.
Low pH can cause damage to metal in the equipment
pack and heaters, excessive sanitizer consumption,
and skin irritation. A pH level above 7.8 can be scale-
forming and allows metals or minerals in the water to
form deposits and stain spa surfaces.
Shocking
Once bacteria and other wastes are neutralized by
the sanitizer, they stay in the water unless oxidized or
shocked. Often called chloramines or bromamines,
they create dull, cloudy water and can cause odor
and eye or skin irritation. Marquis Shock Treatment
rids your spa of these wastes for clear, sparkling
water. Shocking is recommended once a week or
whenever the water appears dull or cloudy or has a
strong chlorine odor.
NOTE: A strong chlorine odor indicates that the
spa needs to be shocked – not that there is too
much chlorine in the water. A properly bal-
anced spa that is shocked regularly will not
have a chlorine odor.
