Draining and Refilling

About every 3 to 6 months, you will want to replace the water
in the spa. Frequency of water replacement depends on fre-
quency of use, care taken in maintaining water quality, etc.

sudsing and/or you can no longer see the normal sparkle to the
water, even though the key water balance measurements are all

WARNING! Turn off power to spa before draining it. Do
not turn the power back on until your spa has been
refilled.

occur in the lines or the equipment (see the section on "Win-
