Filtering Cycles; Filter Cycles - Jacuzzi J-315 Installation Manual And Use & Maintenance

N.B.: always keep at least 6 of these jets open so as to ensure
efficient water filtering.
Adjusting PowerPro Jets
With the nozzles of the PowerPro Jets positioned straight a-
head, the jet stream will be stationary. Pushing the nozzle to one
side causes the jet nozzle to rotate, moving the jet stream in a
circular pattern.
The jets may not spin with the pump on low speed.
Waterfall feature
The cascade effect can be controlled independently.
The JETS 1 Button activates the waterfall feature.
- models J-315/J-325
move the lever (located near the cascade dispenser) inwards to
open or increase the jet of water; move it outwards to decrea-
se or close the water.
- models J-335/J-345/J-355/J-365/J-375
move the knob (located above the cascade dispenser) to the left
(while in the spa) to open or increase the jet of water; move it
to the right to decrease or close the water.
Air controls
Some jets have a dedicated air adjustment button. Press down
on the side with the Jacuzzi logo to open. Press the opposite side
to close the air.
To minimize heat loss, all air controls (side with Jacuzzi logo
up) should be closed when the spa is not in use.
Certain jets may not dispense air when pump 1 runs at low
speed.

Filter cycles

The spa is equipped with a circulation pump that constantly
filters the water. Thanks to the action of this pump and of one
of the two filter cartridges, even the smallest impurities are re-
moved from the water.
N.B.: the circulation pump is also used to circulate heated water
to the spa when the heater is turned on. This feature cannot be
altered or disabled.
I
The control system activates a programmable "standard" or "e-
conomy" skimming/heating cycle. These cycles utilize pump 1 and
the larger filter cartridge end to quickly clean the water and mini-
mize their "bath-tub ring" effect.
Standard skimming/heating modes
(the display shows the codes F0 to F3)
This mode is normally selected in areas with cold climates where
heating times are longer due to a lower ambient temperature.
In these modes, the water temperature is regulated by the set
temperature, circulation pump, and heater which turns on as
needed.
When the programmed temperature is reached, the heater shuts
off and the circulation pump continues running to filter and clean
the water (unless in summer mode; see related chapter).
Economy skimming/heating modes
(the display shows the codes F4 to F6)
This mode is normally selected in areas with cold climates where
heating times are longer due to a higher ambient temperature.
In this mode, the water temperature is regulated by the set tem-
perature, circulation pump, and heater only while a programmed
skimming cycle is running (unless in summer mode; see the rel-
ative chapter on this).
Lock Modes (L1 - L2)
These modes are designed for use during spa service or to pre-
vent unauthorized use.
Economy skimming/heating modes
I
On the control panel, simultaneously hold down both buttons ( + )
and ( - ) and release.
Press either button ( + ) or ( - ) to select the skimming/heating
mode from F0 to F6 or lock modes L1-L2 described below:
I
Standard skimming/heating modes
F0: 5 minutes of skimming per day
(one 5 minute "Blow-Out" cycle every 24 hours to purge all
plumbing lines)
F1: 1 hour of skimming per day
(one 30-minute cycle every 12 hours); this is the factory de-
fault setting.
F2: 1.5 hours of skimming per day
(one 30-minute cycle every 8 hours)
F3: 2 hours of skimming per day
(one 30-minute cycle every 6 hours)
I
Economy skimming/heating modes
F4: 1 hour of skimming/heating per day
(one 30-minute cycle every twelve hours)
F5: 1.5 hours of skimming/heating per day
(one 30-minute cycle every eight hours)
F6: 2 hours of skimming/heating per day
(one 30-minute cycle every six hours)
