9. OPERATION
Once the spa/pool heater is installed, it can be used
year round. The user MUST makes sure the pump is not
disengaged to allow it to run until the desired temperature
setting is reached.
The unit will function only when there is sufficient flow
through it (15 gpm minimum). On the digital control panel
shown in Figure 3, press and hold the knob for five (5)
seconds to check the flow rate in the unit.
The unit also has a one (1) minute built-in TIME DELAY to
protect it from air in the lines and to avoid burning out the
elements as a result of it. When the unit senses sufficient
water flow it will automatically activate.
10. CONTROL
Turn the control knob to set your desired spa/pool
temperature. When the set tempera ture is reached the
heater will go to idle and consume no energy.
Digital Control Temperature Setting
The heater comes with a digital temperature control
located in the front panel that can be easily set from
40°-104°F (4°C-40°C) in one (1) degree increments by a
simple turn of the knob.
The heater can be turned OFF by pushing the control knob
once.
Hold the knob for three (3) seconds to switch from
Fahrenheit to Centigrade.
