11.0 Spa Maintenance

Proper and regular maintenance of your spa will help it retain its beauty
and performance. Your authorized Sundance dealer can supply you with

all the information, supplies and accessory products you will need to
accomplish this.

11.1 Cleaning The Filter

Your new spa is equipped with an exclusive MicroClean

™

2-stage filter

cartridge located under the filter lid. Fine debris are filtered 24-hours
by the circulation pump drawing water through the ultra-fine (stage 2)
cartridge. Larger debris are filtered by the main 2-speed pump drawing

water through the (stage 1) polyester mesh (pleated) cartridge during

normal operation and during each filtration/heating cycle. Combined,
both filter halves work together to give you unsurpassed water quality

by trapping suspended particles on their outer surface.

Note: To ensure

optimum performance, clean and reuse the stage 1 cartridge once a
month and replace the stage 2 cartridge every 3 months,

or as needed.

All models include filters on their footwell suction covers (shown

right) that prevent debris from entering pump 2 and the massage

selector(s), when operating. These filters must remain in place
to protect these components from debris entrapment/damage.

They should be cleaned every 2 months, or when weak pump 2
performance is observed.

ALWAYS TURN POWER TO SPA OFF BEFORE CLEANINg THE

FILTER CARTRIDgE!
