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
REMOvAL
1 Activate the STANDBY/DRAIN ASSIST mode.
2 Remove the cosmetic lid and open the small, black air
vent/bleeder valve on the top of the filter lid.
3 Press down the lock tab to disengage and turn the
locking ring counter clockwise.
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 dealer).
7 A cleaning cylinder may be purchased from your
HYDROPOOL Hot tub dealer.
8 Rinse thoroughly and dry before replacing.
9 It is recommended to purchase a spare filter cartridge so
that you always have a clean substitute ready to rotate.

10 After the element has dried - if necessary, lightly brush
between pleats with a fine paint-brush to remove
remaining dirt particles.
RE-INSTALLATION
11 Place the cartridge filter back into the filter housing.
12 Replace the filter housing lid, pushing it down to seat,
ensuring that the lid o-ring does not become twisted.
13 It is recommended that the lid o-ring be lubricated with a
non-petroleum based lubricant (ie. Silicone gel) when it
becomes dry. This will help to prevent twisting and
pinching as the lid is installed, and significantly increase
longevity of the o-ring.
14 Install the filter lock-ring, turning clockwise until the lock
tab snaps into place.
15 Close the air vent/bleeder valve.
16 Take the system out of STANDBY/DRAIN ASSIST mode.
17 When the pump starts circulating on low speed, it will be
necessary to release trapped air in the filter. Carefully
loosen the vent valve counter-clockwise until there is the
hissing sound of air escaping. Once there is a steady
stream of water, close the vent valve, ensuring that the
o-ring does not become pinched.
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

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 indicated
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.
