Temp no issue. I would however,go over chemicals and maintenance,with your dealer,as soon as possible!Better to be safe,than sorry.Lastly,never shy away from asking questions here,and with your dealer.
I like to see the spa at 90 degrees or more before chlorinating. That way the the chlorine disolves much faster. You also have bateria that are not as active at lower temps so you want to have them at the most vunerable point before chlorination....
