CAUTION: Never leave your spa unattended for any reason
while the cover is open and accessible to small children and
animals!
. Turn off power to the spa at the circuit breaker, then drain spa as
outlined in section .2 (page 25-26).
12. Refill spa with clean tap water from garden hose until water covers
all jets (DO NOT OVERFILL!)
CAUTION: Never fill with water from a water softener. If your

you may fill entirely with hard water if you use a special water

ensure healthy water conditions, always maintain a constant
