SECTION 1 – INSTALLATION

STEP 1: Preparing your pool and filtration system

IMPORTANT

The filtration system must be operating at its MAXIMUM WATER FLOW
before you install your ZODIAC G4™, otherwise you will have to re-adjust
your ZODIAC G4™ after cleaning the pool filter.

Installation is easy if you follow these simple preliminary steps:

1. Empty the weir basket.

2. Clean the pump basket.

3. Backwash the filter until the sight glass is clear.

4. Adjust all return jets (whether your pool has one, two or more) to point
downwards and towards each other so that you DO NOT see a circular
water flow or waves on the surface of your pool.

STEP 2: Assembling the Disc to your G4™

1. Viewed from underneath the unit, the fins on the Disc should point away
from you..

2. Beginning at one corner of the flat front section of the FlexiFoot, stretch the
Disc around to the other corner, until the Disc is held in place by the FlexiFoot.

3. The Disc should rotate freely once installed.

SECTION 1 – INSTALLATION

STEP 3: Assembling the Hoses

1. Always insert the male hose
cuff into the female cuff. Hoses
must connect fairly tightly. The
ideal length of hose is from the
weir to the furthest point of
the pool plus one extra section
of hose. If the weir is opposite
the steps, use lowest step as
furthest point (See Diagram 3
and 4). To ensure the best
performance from your
ZODIAC G4™, please ensure
only genuine ZODIAC long life
hoses are used.

2. Attach your ZODIAC G4™ to the male end (smaller side) of the assembled
hose.

3. Fit the Hose Protection Mesh over the cuff of the hose to help prevent the
hose from wearing at the weir. Position the protection mesh so that ±10 cm
is exposed outside the weir.

Weir

Diagram 4: Ideal Hose Length

4. Bleed all the air from the hose by placing one end over the return jet – thus
filling the hose length with water.

5. Keeping the hose-ends underwater, move it from the return line to the weir
and connect the female cuff directly to the Auto Weir Valve or utilize the 90°
Valve Elbow, depending on your weir configuration (See Diagram 5).

6. Ensure that the Auto Weir Valve is firmly attached to the weir vacum lid .

AUTO WEIR VALVE

The ZODIAC Auto Weir Valve is preset at the factory to obtain
maximum pool cleaning efficiency.Your ZODIAC G4™is preset on
setting 3. However, if you do experience difficulties, it can be manually adjusted

to one of the three settings (high, medium or low).

NOTE: To obtain maximum
diaphragm efficiency, please

ADJUSTMENT SUGGESTIONS

You will only need to adjust the Auto Weir Valve if the following occurs:

SECTION 2 – CORRECT SETTINGS

ADJUSTMENT SUGGESTIONS

CORRECT BALANCING

Proper balancing must be accomplished in the DEEPEST area of the pool. The

™

buoyancy of the hose tends to LIFT the ZODIAC G4
water. The hose weight is utilized to help neutralise the buoyant effect of the
hose. Although usually not required, if a hose weight is needed, please contact
ZODIAC on 0800 110 885 whereby we will supply a hose weight at no charge.

Diagram 6: Positioning of the hose weight (if required)

POOL COVERAGE

Normally it is undesirable for the return line water flow to affect the natural
movement of your ZODIAC hose. However, the return line pressure can
be used to balance cleaning coverage or to guide the cleaner away from steps
and corners.

A return line located anywhere along the shaded area can be utilised to gently
push the hose, allowing your ZODIAC G4

™

to free itself from in-pool obstacles

(Diagram 7).

NOTE: Do not use hose

SECTION 3 – QUICK RELEASE

CASSETTE SYSTEM

The ZODIAC G4™has a long life diaphragm and a Quick Release Cassette
This unique feature allows almost instantaneous access to the diaphragm.

Large foreign objects, such as children’s toys, tree branches and rocks, should be
removed manually from your pool prior to operating an automatic pool cleaner.
In the event of a blockage occuring, the Quick Release Cassette System allows
you the opportunity to remove the blockage or check the diaphragm for damage
in seconds at the poolside.

The Quick Release Cassette System also allows you to reset the diaphragm which
may also resolve performance problems such as: running and stopping,
problems and/or your ZODIAC G4™not climbing the pool walls.

SECTION 3 – QUICK RELEASE

CASSETTE SYSTEM

Remove the diaphragm from the inner extension pipe (Figure 5), leaving the
retaining ring on the diaphragm.

FIGURE 5

STEP 3: Examination

Inspect the diaphragm for a blockage or any damage. Even small holes will
compromise its operation. If any damage is evident, i.e. a cut or hole on the sides
of the diaphragm, replace it.

If there is a blockage, carefully remove it. If this can’t be done, a garden hose may
be used to flush the obstacle through. Do not use any sharp objects to probe or
push an obstruction as this may damage the diaphragm.

STEP 4: Diaphragm Assembly

Prior to re-installing the diaphragm, rinse the diaphragm and the inner extension
pipe thoroughly to remove any grit. Attach the diaphragm to the inner extension
pipe (Figure 6). Slide the top of the inner extension pipe (the end which is
opposite the diaphragm) into the body.

SECTION 3 – QUICK RELEASE

CASSETTE SYSTEM

Pressing on the underside of the diaphragm’s ridges, push the diaphragm into the
cassette body (Figure 7).

FIGURE 7

The diaphragm should fit flush against the cassette body.

STEP 5: Resetting the Diaphragm

If the gap of the throat/diaphragm is excessive (more than 5mm), yet the
diaphragm is not torn or damaged, it can be reset by leaving one ridge on the
diaphragm exposed from the cassette body (Figure 8).This may resolve
performance-related problems such as: running and stopping, coverage problems
and/or your ZODIAC G4™not climbing walls.

Hold the cassette and tighten the extension pipe by turning it clockwise
(Figure 9). Do not overtighten.

SECTION 4 – HOW TO KEEP YOUR

ZODIAC G4

However good an automatic pool cleaner is, remember that it was developed to
assist you with the maintenance of your swimming pool. From time to time it will
need a little assistance from you. Here’s what you can do to help:

1. Weir basket, pump strainer basket, cartridge filter, skim filter, sand filter
(whichever is applicable) should be thoroughly cleaned on a regular basis to
ensure optimum pool cleaner efficiency.

N.B. ALWAYS disconnect the hose from the weir or vacuum line

BEFORE backwashing your filter.

2. Always store your ZODIAC Long Life Hose in a straight line – never coil or
leave hose coiled in sun.

3. Periodically inspect parts for wear.The FlexiFoot, Disc and Bumper fin are the
most critical.As the Disc wears, it begins to curl at the outer edges.When the
depth of the channels between the treads on the FlexiFoot are 3 mm or less,
replace the FlexiFoot.

4. In the event of an object becoming stuck in the diaphragm, clear it quickly and
easily by following the simple instructions laid out for diaphragm maintenance
under Section 3 – Quick Release Cassette System.

5. To maintain optimum performance from your ZODIAC G4
that your cassette diaphragm is reset when required.
(See Section 3: Quick Release Cassette System, page 9, step 5.)

IMPORTANT

Sunlight (ultraviolet rays), water and swimming pool chemicals can take their
toll on your automatic pool cleaner.

™

To extend the lifespan of your ZODIAC G4

1. Ensure that your pH is at the recommended levels as per the table below at all
times as recommended. A low pH is detrimental to most types of plastics and
rubbers and will seriously damage your Automatic Pool Cleaner.

™

2. Remove your ZODIAC G4
and re-install it after a minimum of four hours.

Chlorine:

1,0 – 1,5 ppm

pH Level:

pH Fibreglass: 7,0 – 7,2 pH Marbelite: 7,2 – 7,6

Total Alkalinity:

80 – 120 ppm

NOTE: Due to the harsh environment in which your pool cleaner operates, your ZODIAC G4

may discolour during normal use over a period of time.This, however, will not affect the
cleaning performance of your unit.
