Maintenance

Water Chemistry

You can ensure better water chemistry by testing your hot tub water every day and adjusting
the chemical balance frequently. Obtain a water quality test kit, designed especially for hot
tubs, from your Jacuzzi Premium Spas dealer. The test kit must be of the type which allows
you to test for the disinfectant (chlorine) level, pH, and total alkalinity. Ensure that the chemicals
used in your hot tub are especially for hot tub use, and not for swimming pools, as water
quality maintenance of hot tubs and of swimming pools is very different.
Set up a daily program at first to check the disinfectant level, pH, and total alkalinity of the
water. Familiarize yourself with the amount of chemicals to add and to determine how often to
make chemical adjustments during normal use. Remember that the more heavily the hot tub
is used, the more often you should check the water chemistry.
When adding any chemicals, always run the filter system to ensure complete dilution with the
water.
Do not add chemicals directly into the skimmer.

Disinfecting

When filling the hot tub for the first time, follow the purge/sanitizing instructions in the Equipment
Set-Up procedure of the Installation Instructions.
Add chlorine to the water on a regular basis to help control the amount of bacteria, algae and
organic materials. Such bacterial contaminents, if not controlled, could cause skin rashes or
other physical problems. To disinfect the hot tub for normal use, first establish the amount of
chlorine to add and determine how often you need to add it.
We recommend that you maintain a free chlorine level of 2.0 to 5.0 ppm at all times except
when you must exceed that during the initial purge/sanitizing procedure or during
superchlorination (refer to Water Quality Definitions on page 30). Superchlorinate your hot
tub every two weeks with heavy use. If using sodium dichlor, add one heaping tablespoon for
each 150 gallons of hot tub water. Scrub the hot tub surfaces with this solution to remove any
oily deposits. This will ensure that any bacteria or algae which are resistant to the normal
disinfectant level are killed. After adding the disinfectenct, run the filter system and allow the
free chlorine level to return to the 2.0 to 5.0 ppm range before using the hot tub again.
Do not install a cover until the disinfectant level is back to normal. High concentrations
of chlorine will damage metallic plated finishes if the cover is in place.
