per hour with the optional spa cover, foam insulation and
skirt panels in place and if the air temperature is 10
°
C
(50
°
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
21
°
C (70
°
F) when the spa is not in use, and the desired
temperature is 38
°
C (100
°
F), it will take about 8.5 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.
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 mea-
surement of spa water temperature. Other types of ther-
mometers, generally available, such as those used for
swimming pools, are not sufficiently accurate for determin-
ing spa water temperatures. Take water temperature
readings in the HTR/FILTER mode when the heater has
just turned off; the indicator lamp on the control panel will
turn off at this time.

OPERATION
Temperature Control
Turn on the heater by selecting the HTR/FILTER mode
on the SYSTEM selector switch.
With this selection, you can verify that the spa’s heater
is operating by viewing the HEATER ON light on the spa
side panel.
Set the Temp. Control knob by rotating it to the desired
temperature. (The temperature will be higher as the knob
is rotated clockwise.) When the water temperature is lower
than that set by the heater control, the heater and filter
motor/pump will be activated. The heater and filter func-
tions will automatically turn off when the desired tempera-
ture is reached. When the heater is on, the water is also
being filtered. The heater will also maintain water tempera-
ture in the JETS mode.
The heater control is designed to maintain a minimum
temperature of approximately 7-10
°
C (45-50
°
F), its lowest
setting. This does not necessarily protect the spa from
freezing. See page 15 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 tem-
perature 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 TEMP CONTROL knob to the desired tempera-
ture. The water temperature will rise at a rate of about 2
°
C
