11.0 Hot Tub Maintenance
Proper and regular maintenance of your hot tub 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 accom-
plish this.
11.1 Cleaning The Filter
Your Sundance hot tub is equipped with an exclusive MicroClean
TM 2-stage
filter located under the filter lid (Figure-F, Page 17). Larger debris is filtered by
the main 2-speed pump drawing water through the larger (stage 1) cartridge
during normal operation and at each filter cycle. Fine debris is filtered by the
circulation pump drawing water through the smaller (stage 2) cartridge. Both
halves work together to give you unsurpassed water quality! To ensure opti-
mum performance, clean and reuse the stage 1 cartridge once a month and
replace the stage 2 cartridge every 3 months.
All models include filters on their footwell suction covers (Page 17) that
prevent debris from entering pump 2, when operating. These filters
must remain in place to protect pump 2’s plumbing network. They
should be cleaned every 2 months, or when weak pump 2 perfor-
mance is observed.
ALWAYS TURN POWER TO THE HOT TUB OFF BEFORE CLEANING THE
FILTER CARTRIDGE! To accomplish this, refer to the filter cleaning/
