Periodically, the cartridge will need a more thorough cleaning to remove
imbedded oils and minerals. For this, we suggest cleaning as illustrated above
(Step C), 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 filter cartridge
is approximately two years with proper care and water quality maintenance.
Replacement cartridges may be purchased from your Sundance dealer.
11 .2 Draining and Refilling
About every 3 to 6 months, you will want to replace the spa’s water. The fre-
quency depends on a number of variables including the amount of use, atten-
tion paid to water quality maintenance, etc. You will know it is time for a
change when you cannot control sudsing and/or you can no longer get the
normal feel or sparkle to the water even though the key water balance mea-
surements are all within the proper parameters.
