OPERATION
Heater Control
Turn on the heater by selecting the HTR/FLTR mode on
the SYSTEM selector switch.
With this selection, you can verify that the spa’s heater is
operating by viewing the HEATER INDICATOR light on the
spa control panel.
Set the HEATER CONTROL knob by rotating it to the
desired temperature. The temperature will be higher when
rotated clockwise. When the water temperature is lower
than that set by the HEATER Control knob, the heater and
filter motor/pump will be activated. The heater and filter
functions will automatically turn off when the desired tem-
perature is reached. When the heater is on, the water is
also being filtered. The heater will also maintain water
temperature in the JETS mode.
The HEATER CONTROL is designed to maintain a
minimum temperature of approximately 45-50
o
F, its lowest
setting. See page 15 for winterizing procedures
.
Setting the Thermostat
When your spa has power and HTR/FLTR has been
selected on the control panel, your HEATER thermostat is
working to maintain the temperature to which you have set
the HEATER knob.You will notice by the indicator light that
the heater is on when the water temperature falls below the
desired temperature and will turn off when that temperature
has been reached.
When the spa is not in use, you can set the thermostat to
a lower temperature; then, when you wish to use the spa,
adjust the HEATER CONTROL knob to the desired tem-
perature. The water temperature will rise at a rate of about
6
o
F per hour with the optional spa cover, foam insulation
10
and skirt panels in place, and if the air temperature is 50
o
F
or warmer. This rate will necessitate a waiting period before
using the spa, the length of which will be 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
o
F when
the spa is not in use, and the desired temperature is 100
o
F,
it will take about 5 hours to heat up sufficiently.
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 optional spa cover available 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.
Determining Water Temperature:
As spa products generally perform in a narrow range of
operating temperatures, we recommend that you use a
medical (clinical) type thermometer for an accurate mea-
surement of spa water temperature. Other types of ther-
mometers generally available, such as those used for
swimming pools, are not sufficiently accurate to determine
spa water temperatures. Take water temperature readings
in the HTR/FLTR mode when the heater has just turned off;
the indicator lamp on the control panel will turn off at this
time.
