During certain times of the year, you may not use the spa on a frequent basis. For these low-use or no-use periods, consider the following:
Low Use or No Use for less than Two Weeks
Do not make any changes.
No Use for Two to Six Weeks
If the spa will not be used for at least two weeks, lower the temperature to the lowest setting of 80◦F (26◦C) or place in Sleep Mode. Lowering the temperature will cut the cost of operation, however; you will need to adjust the temperature setting approximately 4 hours before use in order to heat the spa to 100◦F (38◦C).
IMPORTANT: During all low- and no-use periods, be sure to maintain the spa water as per the instructions in the Water Chemistry section.
IMPORTANT: For all no-use periods, and on a weekly basis, be sure to have someone visually check that the spa is functioning correctly and to also maintain the spa water as per the instructions under the Water Chemistry section. Not doing so may lead to corrosion, staining, and/or scaling to the spa and its equipment. During periods of freezing temperatures, a spa that has malfunctioned may be subject to damaged plumbing or equipment as a result of ice buildup within the spa. If the spa cannot be checked and maintained on a weekly basis, then consider winterization.
