Attention New Spa Owner!
Congratulations on the purchase of your new Sundance® 780 series spa! The
following is a list of automated functions and maintenance recommendations
for your new spa. Automated functions have been listed below in an attempt to
suppress any operational concerns you may have during startup and the rst
24-hours of ownership! Maintenance recommendations are listed in an attempt
to stress their importance in protecting your new spa.
Automated Operations
Approximately two minutes after power is applied to the spa, the rst ltration/
heating cycle turns on pump 1 (see sec. 9.0, page 23). In Certa/Chelsee/
Hamilton models, an automatic ve minute “blow-out” function also activates
pump 2 for a period of ve minutes to ush all lines. Then, after ve minutes,
pump 2 turns off and pump 1 continues to operate for the duration of the cycle.
Note: this function only occurs during the rst ltration/heating cycle each day.
Maintain Healthy Spa Water
Always maintain your hot tub’s water chemistry within the following
parameters as dened by the Association of Pool And Spa Professionals/USA:
pH 7.4 - 7.6
Free Chlorine 3.0 - 4.0 ppm
Free Bromine 2.0 - 4.0 ppm
Total Alkalinity 100 - 120 ppm
Calcium Hardness 150 - 250 ppm
Always maintain your spa lter as outlined below to ensure healthy spa water.
Refer to page 29-30 for additional information.
Required Filter Maintenance
Your new hot tub is equipped with an advanced 2-stage MicroClean™water
ltration system that provides unsurpassed water quality! To ensure maximum
water quality at all times, you should clean and reuse the larger pleated lter
cartridge every month and replace (throw away) the smaller MicroClean lter
cartridge every 3 months, or earlier as necessary. The smaller MicroClean lter
cartridge is designed to be thrown away! Attempts to reuse this lter cartridge
may result in the re-release of unwanted particles back into the spa. See page
29-30 for detailed lter cartridge replacement instructions.
Required Water Maintenance
You should replace the spa’s water every 3 months. The frequency depends on
a number of variables including frequency of use, number of users, 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. See page 36 for additional information.
