Function Selector Switch; Setting The Thermostat; Notes On Determining Water Temperature - Jacuzzi Z100 Owner's Manual

Function Selector Switch

To ensure your safety and allow easy operation, your
spa is equipped with an air-activated function selector
switch located on the side panel of the redwood skirt, near
the front corner of the spa. This push-button switch selects
the following four functions in the continuous sequence
indicated:
1. OFF
2. WHIRLPOOL
3. HEATER/FILTER
4. FILTER ONLY
(The next selection is OFF again.)
You know which function you are selecting when the
whirlpool system is activated. Use that function as a
reference to indicate your location in the function se-
quence, since that function is the most obvious when
operating.
For best performance, pause a second or two between
push-button selections.

Setting the Thermostat

Turn on the heater by selecting the HEATER/FILTER
mode on the selector switch. You can verify that the spa's
heater is operating by looking through the small factory-
drilled hole located in the door panel of the spa and
checking that the red indictor light is illuminated.
The thermostat adjustment knob is located on the front
of the heater. To set the thermostat, turn the knob to the
desired temperature. If the water temperature reaches a
level higher than you wish, turn the thermostat knob back
to a lower setting. The spa's water temperature will stabilize
after a while and fall a few degrees before the heater turns
on again. When the water temperature reaches the tem-
perature set on the thermostat, the heater and motor/pump
will turn off automatically.

The water temperature will rise at a rate of about 2
hour, depending on the temperature of the air surrounding
the spa. This rate requires a waiting period before using the
spa, the length of which is determined by the temperature
of the water before turning on the heater. For example, if
the water in the spa is kept at about 70° F when the spa is
not in use and the water temperature at which you plan to
use the spa is 100° F, then it will take about 15 hours to heat
up to the desired 100°F temperature.
Once you have determined the desired setting on the
thermostat knob, it is not necessary to change or readjust
it again during normal operation unless you decide on a
different setting.
The spa cover provided for your spa will help control
heat loss from the water surface and thereby reduce energy
consumption. You can improve the spa's heat retention by
keeping the spa cover in place on the spa while heating the
water.
Notes on Determining Water Tem-
perature:
As spa products generally perform in a narrow range of
operating temperatures, we recommend that you use a
medical (clinical) thermometer for an accurate measure-
ment of spa water temperature. Other types of thermom-
eters generally available, such as those used for swimming
pools, are not sufficiently accurate to determine spa water
temperatures. Take water temperature readings in the
HEATER/FILTER mode when the heater has just turned
off; the indicator lamp on the heater housing will turn off at
this time.
