The spa will start itself up and begin filtering and heating the spa until it reaches the factory set temperature of 38 degrees. It will also start filtering the water based on the factory settings. If your touchpad is not illuminated, you’ll need first to wake it up by pushing the POWER button. Now set the time and adjust the temperature. The time can be set by pushing the TIME button, then the MODE button. Use the WARM or COOL buttons to change the time and the MODE button to confirm each setting. To set the filter times press the TIME button once, then the MODE button three times, then set the start and end times of each of the two filter periods using the WARM or COOL buttons followed by the MODE button to confirm your settings. Two hours per filter period is suggested but this can be increased in times of heavy use. The temperature can be set by either pushing either the WARM or COOL buttons, then once a temperature is flashing, use the UP and DOWN buttons to select the new desired temperature. If you don’t want people using your spa or changing settings, you can lock the control panel by pushing the WARM and COOL buttons at the same time. Unlock by pushing the same buttons again. You can invert the display panel also by pushing the TIME and WARM button at the same time, and to swap it back push them again. There are other non-essential settings and features which may also be of interest, these are explained in your manual and on the DVD supplied in your spa warranty kit.
