CARTRIDGE FILTER
The cartridge should be cleaned every two to four weeks, depending on the amount of use.
Signs that the filter requires cleaning include:
• Reduced jet power
• Hazy gray water
• Rattling noise in the pump or filter
• Heater not working

4. Pull the filter lid upwards, and lift the cartridge element straight up and out of filter housing.
CLEANING
5. With a garden hose and spray nozzle, hose off the cartridge element, ensuring to carefully separate every
pleat.
6. To remove collected lotions, body oils, etc. soak the cartridge in warm water and a filter
cleaning/emulsifying compound (available at your HYDROPOOL retailer).
7. A cleaning cylinder may be purchased from your HYDROPOOL Hot tub Retailer.
8. Rinse thoroughly and dry before replacing.
9. Hydropool recommends purchasing a spare filter cartridge so that you always have a clean substitute
ready to rotate.

remaining dirt particles.
Do not use a wire brush or other devise to clean cartridge element.

CHANGING THE HOT TUB WATER
A hot tub should be drained every 8-12 weeks, depending on size and amount of use. If your hot tub is used
daily or by a large number of bathers, the water should be drained more often. One method to determine the
approximate length of time between water changes is to divide the water volume (in liters) of your hot tub by
13.5 and then divide by the average number of bathers each day.
