not in use. Certain jets may not draw air when jets pump 1 is running in low speed;
this is considered normal.

10.10 Optional Audio System (J-335 - J-375)

Spas equipped with the optional Jacuzzi audio system offer
enhanced enjoyment. These models include an integrated
AM/FM/CD receiver with four high-quality marine speakers for
unsurpassed sound quality and long-life. Refer to section 17.0,
(page 41)

11.0 Automatic Filtration Cycles

Your new spa includes a 24-hour circulation pump which filters the water
continuously. The circulation pump draws water through the skimmer bag and
one of two filter cartridges to effectively remove small debris in your spa. Note:
the 24-hour circulation pump system also supplies heated water to the spa when
the heater turns on.
The control system activates a programmable "standard" or "economy" filtra-
tion/heating cycle to remove larger debris missed by the 24-hour circulation
pump filtration system. These cycles utilize pump #1 low speed and the second
filter cartridge to quickly "skim" the water of large debris and minimize their
"bath-tub ring" effect. Apart from their skimming benefit, each mode also effects
the operation of your spa' s heater. Refer to sections 11.1 and 11.2 below for
additional information.

11.1 Standard Filtration/Heating Modes (F0-F3)

Standard filtration/heating modes are typically selected by customers in cold
climates where heat up times are extended due to lower ambient temperatures.
In these modes, the water temperature is regulated by the set temperature,
24-hour circulation pump, and heater which turns on as needed. After the
programmed set temperature is reached, the heater turns off and the circula-
tion pump continues to operate 24-hours to filter and clean your spa unless in
summer logic; see section 14.1, page 33.

11.2 Economy Filtration/Heating Modes (F4-F6)

Economy filtration/heating modes are typically selected by customers in warm
climates where heat up times are minimized due to higher ambient tempera-
tures. In these modes, the water temperature is regulated by the set temperature,
24-hour circulation pump, and heater only while a programmed filter cycle is
running (unless in summer logic; see section 14.1, page 33).
