You may use heated water to fill the spa, which will shorten the initial heat-up time. However, make sure not to use water exceeding the normal spa operating temperatures which are not to exceed 104°F (40ºC). Water over 104°F (40ºC) will turn off the heating unit and is not considered safe. Always check the water temperature in your spa before use and refer to the manual for detailed information on safe use.
