We recommend that you always have your spafull of water and running at normal spa temperatures (80˚F to 100˚F, 26.7°C to 37.8°C). This will help reduce the risk offreezing in your spa and your spa’s equipment.Warning: If you find the need to drain your spa, be aware of the potential of freezing in your spas equipmentand plumbing. Even if the directions below are followed perfectly, there is no guarantee that your spa willnot suffer freeze damage. Freeze damage is not covered by your warranty.Winterizing (Cold Climate Draining)1. Remove the filter baskets and filters.2. Drain your spa completely as described in theinstructions above.3.

It is far less expensive to fix waterclarity problems by filtering your spa than by using excessive amounts of chemicals, excessive filtration times, or by waterreplacement.See the section “Cleaning the Filter” on page 28 for more information.Set the spa in Hold Mode before you remove the filter. Hold Mode pauses all spa operations for 60 minutesfor service functions like cleaning or replacing the filter. See page 13 for instructions on using Hold Mode.1. Remove the filter by unscrewing it and pulling it up and out.2. Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz. of liquid filter cleaner to the bucketof water.Note: It is a good idea to keep a spare filter to use in the spa while the dirty filter is being deep cleaned. This way, youcan rotate the filters and both will last longer.3. Soak the filter for a minimum of 24 hours.4. Spray the filter with a water hose. Spray each pleat carefully.5. Reinstall the filter.
