pending 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
REMOVAL
1 Activate the HOLD/STANDBY mode.
2 Remove the filter cover and place to the side.
3 Rotate the locking flange counter clockwise to disengage.
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 car
tridge in warm water and a filter cleaning/emulsifying com
pound (available at your HYDROPOOL retailer).
7 A cleaning cylinder may be purchased from your HYDRO
POOL 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.

tween pleats with a fine paint-brush to remove remaining
dirt particles.

clean cartridge element.
Do not put in dishwasher or washing ma-
chine.
RE-INSTALLATION
11 Place the cartridge filter back into the filter housing.
12 Rotate the flange clockwise until it locks in place.
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.
Formula (_______ ÷ 13.5 ) ÷ (________) = (_______)
Volume
of water
in liters
EXAMPLE:
1000 liters divided by 13.5 divided by 2 = 37 days.
The hot tub water must be changed when the amount of
dissolved solids becomes excessive, and is usually indi-
cated by "gray" or dull looking water.

WATER SOFTENERS

Never fill a hot tub with water from a water softener, as it
could adversely effect the water chemistry, making it difficult
to maintain proper water balance. If you live in an area with
hard or soft water, give careful attention to your Calcium
Hardness level. Topping Up with soft water is acceptable.
