Draining And Refilling - Sundance Spas 780 series Owner's Manual

780 SERIES
Periodically, the polyester mesh (pleated) 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.
CAUTION: RISK OF PRODUCT DAMAGE!
• Never scrub the polyester mesh filter cartridge with a brush as
this will cause the polyester mesh to wear out and come apart.
• Never let the spa pump run or have a filter cycle come on with-
out a filter cartridge in the skimmer compartment. Running the
spa without a filter cartridge may permit debris to enter the spa
plumbing and void the warranty!
The average life expectancy of the polyester mesh filter cartridge
is approximately two years with proper care and water quality
maintenance. The smaller stage 2 filter cannot be cleaned and must be
replaced (thrown-out) every 3 months, or as needed. DO NOT reuse this
cartridge! Attempts to reuse this cartridge will reintroduce debris back
into your spa! Replacement cartridges may be purchased from your
Sundance 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 and attention paid to water quality maintenance. 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.
CAUTION! READ THIS BEFORE DRAINING: To prevent
!
damage to the spa's components, turn off power to the spa
at the circuit breaker before draining it. Do not turn the power
back on until your spa has been refilled. There are certain
precautions to keep in mind when draining your spa. If it is
extremely cold, and the spa is outdoors, freezing could occur
in the lines or the equipment (see "Winterizing", Section 11.7
page 39). On the other hand, if it is hot outdoors, do not
leave the spa's surface exposed to direct sunlight for long
periods.
