Section1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
This product should only be installed and serviced by a qualified pool professional and conform to all
national, state, and local codes. When installing and servicing, basic safety precautions should always be
followed, including the following:
WARNING
Do not connect system to an unregulated city water system or other external source of pressurised water producing
pressures greater than 250 KPA (36 PSI).
Pressurised air in system can cause the filter lid to be blown off which can result in death, serious personal injury,
or property damage. Be sure all air is out of system before operating or testing the equipment.
WARNING
MAXIMUM OPERATING PRESSURE OF THE FILTER IS 250 KPA (36 PSI). NEVER SUBJECT THE FILTER TO
ANY OPERATING PRESSURE EXCEEDING 250 KPA (36 PSI).
This filter operates under high pressure. When any part of the circulating system, i.e., filter, pump, valve(s), clamp,
etc. is serviced, air can enter the system and become pressurised when the system is restarted. Pressurised air
can cause the filter lid to be blown off which can result in death, serious personal injury or property damage. To
avoid this potential hazard, follow all of the instructions in this manual.
WARNING
To minimise risk of severe injury or death the filter and/or pump should not be subjected to the piping system
pressurisation test.
Local codes may require the pool piping system to be subjected to a pressure test. These requirements are
generally not intended to apply to the pool equipment such as filters or pumps.
Zodiac equipment is pressure tested at the factory.
If however this WARNING cannot be followed and pressure testing of the piping system must include the filter and/
or pump BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS:
Check all clamps, bolts, lids, lock rings and system accessories to ensure they are properly installed and secured
before testing.
RELEASE ALL AIR in the system before testing.
Water pressure for test must NOT EXCEED 250 KPA (36 PSI).
Water temperature for test must NOT EXCEED 38°C (100°F).
Limit test to 24 hours. After test, visually check system to be sure it is ready for operation.
Notice: These parameters apply to Zodiac equipment only. For non-Zodiac equipment, consult equipment
manufacturer.
WARNING
Chemical spills and fumes can weaken pool/spa equipment. Corrosion can cause filters and other equipment to
fail, resulting in severe injury or property damage. Do not store pool chemicals near your equipment.
WARNING
Incorrectly installed equipment may fail, causing severe injury or property damage.
WARNING
To reduce the risk of injury, do not permit children to use this product.

ZXC-SERIES™ | Installation and Operation Manual
2.3 Description
Cartridge filters do not require sand or
diatomaceous earth as the filter medium. Instead,
the filter contains filter elements which are easily
removed for cleaning or replacement.
Dirty water flows into the filter tank through the
water line connected to the inlet of the tank body.
It is directed through the filter cartridge inside of
the filter. The debris is collected in the filter and the
clean water flows out of the filter through the outlet
on the bottom of the tank body. Clean water is
returned through the piping system to the pool.
As debris collects in the filter, the pressure will
rise and water flow to the pool will reduce. It is
necessary to remove the filter cartridges and clean
them with soap and water on a regular basis in
order to prevent pressure from rising too high and
water flow reducing too low. Refer to Maintenance
Schedule Section 5.2.
NOTE: A filter removes dirt and other suspended
particles but does not sanitise the pool.
Pool water must be sanitised and chemically
balanced for clear water. The filtration system
should be designed to meet local health codes.
Section2. General Information

8. Once water begins to flow from the valve,
tighten to close. Check there is a good flow of
water back into the pool.
9. Watch the pressure gauge to make sure the
pressure stays below 250 kPa or 36 PSI. If the
pressure approaches 250 kPa, immediately
turn the pump off and clean the filter
cartridges (see Section5 “Maintenance”).
If the pressure remains high after cleaning
the filter, refer to the troubleshooting guide
(Section6 “Troubleshooting”) for possible
causes and solutions.
10. When the filter is first installed, make a note of
the pressure gauge reading in the Equipment
Information Record Table (page 2). Follow the
Maintenance Schedule to clean or replace the
cartridge when the flow to the pool reduces or

Page 11
ZXC-SERIES™ | Installation and Operation Manual
the pressure gauge increase is more than 20
kPa. (see Section5 “Maintenance”).
Section5. Maintenance
5.1 General Maintenance
Filter incorporates moving parts and withstands
high velocity water with chemicals in it. It is
important to note that over time some of these
parts will wear in the normal course of use and
require regular checks, maintenance and possible
replacement.
Performing the maintenance checks below will
help to identify parts that have worn and require
repair/replacement before further serious damage
is sustained. Please note that repair/replacement
of moving parts due to regular wear and tear are
the responsibility of the pool owner(s) and are not
deemed to be covered under warranty. A small
amount of regular care and attention to pool
equipment will help ensure long life and trouble-
free performance.
5.2 Maintenance Schedule
Fortnightly
MAINTENANCE CHECK: Check pressure gauge - If
pressure increase is greater than 20kPa, cleaning may be
required.
SERVICE ACTION (if needed): Clean elements using a
garden hose with nozzle or purpose element cleaner In
accordance with instructions.
Three Monthly
MAINTENANCE CHECK: Check inlet/outlet O-rings for
leaks.
SERVICE ACTION (if needed): Isolate Pump, turn power off,
clean and grease O-rings or replace if necessary.
MAINTENANCE CHECK: Check operation of pressure
gauge – salt water can prematurely reduce the life of a
gauge.
SERVICE ACTION (if needed): Replace gauge if required.
Annually
MAINTENANCE CHECK: Compare operating pressure of a
cleaned filter to initial pressure (when new).
SERVICE ACTION (if needed): If pressure is more than
30 – 40 kPa different from cleaned elements to new filter,
replace elements.
MAINTENANCE CHECK: Check for signs of damage to
elements.
SERVICE ACTION (if needed): Replace elements.
IMPORTANT NOTE:
Regular maintenance is important to ensure
long life and trouble-free performance of
your pool equipment. If unable to perform the
maintenance yourself, please contact your local
pool professional, or an authorised dealer who will
be happy to send a trained service technician to
perform the maintenance for you.
For help finding an authorised dealer, use the
dealer locator available at:
www.zodiac.com.au/find-a-dealer (Australia)

5.3 Filter Cartridge Cleaning/
Replacement
1. Turn off the pump and any additional power
source that is connected to assure the system
will not inadvertently start during service.
IMPORTANT: Open the air relief valve (also known
as air bleed valve) about three-
quarter turn on the filter lid and wait
until the pressure gauge reading is
zero (0).
2. Close the filter isolation valves (suction and
return) on the system to prevent flooding.
3. Remove the drain cap located at the bottom
of the filter main body to drain water (Figure
14).

6. Once lid is free of the body, lift lid and locking
ring together and place in a clean location.
You can now remove the filter cartridge
(Figure 16).
Figure 16. Removing Cartridge
7. Pull the cartridge out of the filter tank. If
replacing the cartridge with a new one, skip
this step.
To clean the filter: Spray any debris from the
filter with a garden hose. Set your hose to a
gentle spray and wash off any large debris that
you can see on it.
Spray the filter right away before it dries after
you have removed it from the system. Drying
will allow the collected debris to set into the
filter media, making it more difficult to remove
later.
When spraying down the filter, be sure to
get in between the pleats on the filter. This is
where a lot of large debris can collect.
NOTE: Special formulated filter element cleaning
solutions can be purchased from most pool
professionals.
NOTE: Do not use high powered water jets to clean
the elements, which may cause damage. Using
a garden hose with nozzle will do the job safely.
8. Using a new or cleaned cartridge, place the
cartridge into the filter tank. Be sure that
the filter cartridge is correctly seated on the
cartridge support at the bottom spigot of the
filter main body (Figure 17).
Cartridge Support
Figure 17. Cartridge Support
9. Inspect the main O-ring at the lid for cracks
and wear marks. Replace if necessary. Use
only a non-petroleum based lubricant on all
gaskets and lid O-rings.
10. Replace the lid and locking ring assembly
onto the top of the filter tank, ensuring correct
alignment with the threads.
11. Tighten the lid locking ring in a clockwise
direction. The lid will pull down onto the filter
