skirt panels in place and if the air temperature is 50
°
F or
warmer. This rate will necessitate a waiting period
before using the spa, the length of which will be deter-
mined 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 desired
temperature is 100
°
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 re-
adjust 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.
Note on 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
measurement of spa water temperature. Other types of
thermometers, generally available, such as those used
for swimming pools, are not sufficiently accurate to
determine spa water temperatures. Take water tem-
perature 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.

OPERATION
TEMP. CONTROL
Turn on the heater by selecting the HTR/FLTR mode
with the SYSTEM switch.
With this selection, you can verify that the spa’s heater
is operating by viewing the indicator light on the spa
control panel.
Set the HEATER knob by rotating it to the desired
temperature. When the water temperature is lower than
that set by the HEATER knob, the heater and filter motor/
pump will be activated. The heater and filter functions will
automatically turn off when the desired temperature 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 mini-
mum temperature of approximately 45 - 50
°
, its lowest
setting. This does not necessarily protect the spa from
freezing. See page 14 for winterizing procedures.
Setting the Thermostat
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 knob to the desired tempera-
ture. The water temperature will rise at a rate of about 6
°
per hour with the optional spa cover, foam insulation and
