OPERATION
Setting the Timer
The built-in 7-day timer is located in the System
Control Module. The tooth-like tabs that are located on
the dial can be set to activate the filter system for two-
hour periods on any day(s) of the week. First set the
correct time. Set the time of day by rotating the outer dial
and aligning the correct time with the small arrow in the
inside of the dial. Note: Both correct time and day must
be set. Next slide one of the tabs toward the center of
the dial at the time at which you wish the filter system to
operate. Note that the timed mode can begin at any time
of day or night on any specified day of the week.

230 Volt Operation
If your spa has been converted to 4-wire, 230 Volt, 50
AM P, there are a few difference in operation. First, all
features are operational and there are no overriding
functions. Additionally, after converting to 230 V, the
spa's heating time be approximately 8
°
per hour instead
of 2
°
.
Finally, whenever you need to perform maintenance
on the spa, or when you need to drain the spa to below
its normal operating level, make sure power to the spa
is turned off at the house service panel, as there will be
no power cord to unplug.
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.

Setting the Thermostat
When your spa is plugged in and HTR/FLTR has
been selected on the control panel, your heater thermo-
stat 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 thermo-
stat to a lower temperature; then, when you wish to use
the spa, adjust the HEATER knob to the desired tem-
perature. The water temperature will rise at a rate of
about 2
°
per hour with the optional spa cover, foam
insulation and skirt panels in place and if the air tempera-
ture is 50
°
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
°
when the spa is not in use, and
the desired temperature is 100
°
, 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
Temperature 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 minimum temperature of approximately 45-
50
°
F, its lowest setting. This does not necessarily
protect the spa from freezing.
