All baths manufactured by Jacuzzi Whirlpool Bathare equipped with fully adjustable PowerPro ® jets, whichare adjustable for all three factors. Some baths haveadditional directionally adjustable jets which can beadjusted for direction and flow of air only.Direction: To change the direction of the water flow,swivel the jet nozzle to the desired angle. The jets canbe directed individually toward any location on your bodyto provide a hydromassage. The jets can also be ad-justed so that they all point in the same direction (clock-wise or counterclockwise) to circulate the water in a cir-cular motion around the bath, causing a total whirlpooleffect.DIRECTIONALLYADJUSTABLEFULLYADJUSTABLEJETSTURN CLOCKWISE TOREDUCE AIR FLOW TURN COUNTER-CLOCKWISETO INCREASE AIR FLOWAIR INDUCTION CONTROLSWater Force: The high volume, fully adjustable jetscan be adjusted to control the force of the water cominginto the bath. For robust action, increase the force ofthe flow by rotating the jet handles to the left (counter-clockwise). For a more gentle effect, rotate the handlesto the right (clockwise). Never run the whirlpool sys-tem with all the jets closed.Force of Air: Two knobs located on the bath serveas controls for the air induction system. The intensity ofthe hydromassage whirlpool action is determined by theamount of air inducted into the water. As the amount ofair is increased, the hydromassage action increases.For maximum air induction, rotate the control knobs fullycounterclockwise to the largest circles. For fewer airbubbles, decrease the amount of air induction by rotat-ing the control knob clockwise. When the knobs areturned to the smallest circles, only water is beingcirculated.OPERATIONPUSH TO RESETOVER HEATPROTECTIONHIGH LIMIT RESETHEATER ONHEATER ONBack Massage Jet - Flow Adjustment10Jacuzzi Whirlpool Bath© U961000F 12/04
