Where are Marquis hot tubs manufactured?
How do I set the temperature on my Marquis hot tub?
Press the TEMP+ or the TEMP- pad. Each pad press changes the set temperature by one degree. Tempera- ture can be set between 80°F and 104°F (26°C and 40°C). When the spa is heating the Heat icon will be shown in the lower right corner of display.
Why is my hot tub not heating?
If your spa heater won't heat, remove and clean the filter(s) to rule out a pressure or flow rate problem in your hot tub heater. Low water level, a clogged pump impeller, closed valves, clogged pipes, or blocked spa drain covers can also cause flow issues.
