Periodically, the stage 1 filter will need a more thorough cleaning to remove
imbedded oils and minerals. For this, we suggest cleaning as illustrated
above (step D), followed by soaking the filter overnight in a plastic container
filled with a solution of water and a specially formulated filter cleanser
available from your Sundance dealer.
The average life expectancy of the stage 1 filter is approximately two years
with proper care and water quality maintenance. The smaller stage 2 fil-
ter cannot be cleaned and must be replaced (thrown-out) every
3-months, or as needed. Attempts to reuse this cartridge will reintroduce
debris into your hot tub! Replacement cartridges may be purchased from
your Sundance dealer.
Note: Nylon suction filters need to be cleaned periodically for optimum
performance of all jets (See Figure-F, Page 14).
