Draining And Refilling - Sundance Spas 680 Series Owner's Manual

During spa use or an automatic filter cycle, water flows through the
spa skimmer and into both polyester mesh filter cartridges to trap
suspended particles and oils on their surface pleats. To ensure optimum
performance, it is necessary to remove and clean both filter cartridges
once a month or sooner depending on spa use and water quality.
B. Denali, Edison, Peyton and Tacoma Models:
Your Sundance spa is equipped with a skimmer basket and
filter cartridge located in the skimmer/filter well. Filtering
is accomplished when the pump turns on in low speed
to initiate water flow through the skimmer basket and
polyester mesh filter cartridge. As this happens, suspended
particles become trapped on the filter's surface. To ensure
optimum performance, it is necessary to remove and clean
the skimmer basket once a week and filter cartridge once a
month or sooner, depending on usage and water quality.
C. Cleaning Procedure (for All Models):
1. Turn off power to the spa at the home's breaker panel or select
the L1 "Lock" mode (page 30) to disable all spa functions.
2. Remove the filter strainer lid or skimmer assembly.
3. Remove the filter cartridge by rotating it counterclockwise to
unthread it from the filter wall fitting, then lift it straight up to remove
from filter well.
4. Using a garden hose with a high-pressure nozzle to rinse debris from
the filter pleats beginning at the top and working your way downward.
Continue, one section at a time, until you have rinsed all of the filter's
pleats.
Periodically, the filter cartridge will need a more thorough cleaning to
remove imbedded oils and minerals. For this, we suggest cleaning as
above and then soaking the cartridge overnight in a plastic container
filled with a solution of water and a specially formulated filter cleanser
available from your authorized Sundance dealer. The average life
expectancy of a Sundance filter cartridge is approximately two years with
proper care and water quality maintenance. A replacement cartridge may
be purchased from your dealer.

Draining and Refilling

About every 3 months, you will want to replace the spa's water. The
frequency depends on a number of variables including the amount of
use, attention 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 measurements are all within the proper parameters.
