| 1. A method of moving a spa cover with a spa cover lifter from a closed position covering a mouth of a spa to a storage position
exposing the mouth, the spa cover including a first leaf pivotably mounted to a second leaf at a hinge and the spa cover lifter
including a lifting arm assembly, a drive mechanism and a controller, the method comprising the steps of:
a. positioning the spa cover over the mouth in a closed position such that the first leaf and the second leaf are generally
located on a cover plane, a first exposed face of the first leaf and a second exposed face of the second leaf facing away
from the spa in the closed position;
b. actuating the drive mechanism to engage the lifting arm assembly with the second leaf to pivot the second leaf about the
hinge such that the first exposed face is facing the second exposed face and the first leaf and the second leaf are positioned
in an intermediate position; and
c. actuating the drive mechanism to engage the lifting arm assembly with the cover to pivot the cover to the storage position.
