Sundance Spas 850 - Manual (Page 36)

The average life expectancy of the stage 1 filter is approximately two years
with proper care and water quality maintenance. The stage 2 filter cannot
be cleaned and must be replaced every 3-months, or as needed.
Replacement cartridges may be purchased from your Sundance dealer.
Note: Nylon suction filters need to be cleaned periodically for optimum
performance of all jets (See Figure-F, page 17).
11.2 Draining and Refilling
About every 3 to 6 months, you will want to replace the hot tub’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.
CAUTION! READ THIS BEFORE DRAINING: To prevent damage to the
hot tub’s components, turn off power to the hot tub at the circuit
breaker before draining it. Do not turn the power back on until your hot
tub has been refilled. There are certain precautions to keep in mind when
draining your hot tub. If it is extremely cold, and the hot tub is outdoors,
freezing could occur in the lines or the equipment (see “WINTERIZING”,
page 35). On the other hand, if it is hot outdoors, do not leave the hot tub’s
surface exposed to direct sunlight for long periods.
To drain your hot tub using the drain port provided, first turn off the power
to the hot tub at the circuit breaker. Then remove the center panel from
the side of the cabinet under the control panel. The drain port is secured to
the base inside the door and features a white “T” handle (Figure-A, Page 10).
To attach a garden hose, replace the fitting screwed into the end of the drain
port with the fitting provided with your hot tub (in the plastic bag with your
colored lenses). For faster draining, a special, large-diameter drain hose is
available from your Sundance dealer.
Once the hose is connected and the end placed where you want the water
to drain, open the valve by pulling the “T” handle outward from the pipe.
After draining, always remember to close the "T" handle valve and reinstall the
threaded plug (to prevent water from seeping past the valve) prior to refilling.
After refilling, turn on power to the hot tub and follow the steps listed under
"Start-Up Instructions" (page 13).
