needed. Attempts to reuse this cartridge will reintroduce debris back into
your hot tub! Replacement cartridges may be purchased from your Sundance
dealer. NOTE: Nylon suction filters need to be cleaned periodically for opti-
mum performance of all jets (See Figure-F, page 16).

1 1.2 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 out-
doors, freezing could occur in the lines or the equipment (see "WIN-
TERIZING" page 36). On the other hand, if it is hot outdoors, do not
leave the hot tub's surface exposed to direct sunlight for long periods.
Draining Procedures:
For Hot Tubs with An External Drain Valve
1. Turn off power to hot tub at breaker.
2. Locate the 3" gray drain valve cap on the left or right side of the hot
tub. Unscrew drain valve cap to expose the underlying male garden hose
fitting. Attach hose to fitting and route opposite end away from hot tub.
3. Pull outward on garden hose at drain connection (approx. 3/8") to open
valve and release water. Water drains at approximately 3 gallons per
minute.
4. Close drain valve by pushing inward on garden hose at drain connection
until you feel it bottom out, then remove garden hose, install gray drain
cap, and refill spa. Refer to "Start-Up Instructions" (page 13).
For Hot Tubs with An Under Cabinet (Hidden) Drain Valve
1. Turn off power to hot tub at breaker
2. Remove front center cabinet under the hot tub control panel.
3. Locate the white "T" handle drain valve secured to base (Fig-A, Page 10)
4. Attach a garden hose to the threaded drain valve port using the adapter
fitting provided with your hot tub (in plastic bag with the colored lenses.)
For faster draining, a special, large diameter drain hose kit is available
from your Sundance dealer.
