FiltrationThe filter is the part of your spa that removes the debris from the water and needs to be cleaned on a regular basis tomaximize your spa’s filtering performance and heating efficiency.It is extremely important that you never run the spa without a filter. There is a possibility that debris maybe sucked into the plumbing through the filter well.In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned periodically todissolve scale and particles that get lodged deep within the filter fibers and impede the filtration process. Even if the filterlooks clean, scale and particles can clog the fibers and prevent water from flowing through the filter resulting in the mostcommon spa problem—no heat, caused by a dirty filter.We recommend you clean your filter at least once a month, possibly every two weeks depending on how frequently youuse your spa, and replace it once a year or as necessary. See page 38 for instructions on removing and cleaning the filter.See page 14 for instructions on using the control panel to change filtration settings.When your spa is first powered up, the filtration setting defaults to the factory setting, which is one two-hour filtrationcycle per day. This is adequate for light to moderate usage (see the topic “Bather Load” on page 32), but if you use yourspa frequently or have a large number of people using it, you will need to increase the filtration.You have two filtration cycles available, although the second one is off by default. You can turn the second cycle on ifyou want additional filtration time, or if you want to divide the filtration times. You can also set filter cycles 1 and 2 fordifferent durations if you wish. Some spa owners set a long second filtration cycle to run at night when electrical powerrates are lower.If you set the spa in READY Mode (see page 12), the circulation pump will run as the spa maintains the set temperature.However, if you set it to REST Mode, the spa will heat only during filtration cycles. If this is the case, if you use the spa inthe last afternoon, you may want to set the first filter cycle to run a few hours before you use it so the water will be warm.We recommend you trying different times and durations for the filter cycles until you find a filtration plan that works foryou.Shocking the WaterIn addition to using a chemical sanitizer, you will periodicallyneed to shock the water. Shocking helps refresh the waterby breaking down organic waste contaminants whichcause odor and cloudy water. After treatment, waterquality and clarity is often completely restored.The two types of shock are sodium dichlor and potassiummonopersulfate (MPS). You can use either type of shockregardless of which sanitizer you use. Even if you usebromine, you can use a chlorinated shock if you wish -- infact, you may find a chlorinated shock is more effectivethan dichlor or MPS alone.If irritating chloramines are present, shocking also convertsthem back to active chlorine. If you use bromine sanitizer,shocking activates the bromide ion (which by itself has nodisinfecting capability) which becomes hypobromous acid inwater, a good sanitizer.Add one ounce of oxidizer shock once a week, afterheavy bather loads, or if water has a strong odor.Spa must be running with all of the jets on high for 30minutes with the cover open. If necessary, repeat shock in30 minute intervals.
