replacement procedure below:
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 avail-
able from your Sundance dealer.
