Introduction
The Salt & SwimTM is an automatic chlorine generation system for pool sanitisation. It is
designed for swimming pools up to 90,000 litres only. The Salt & Swim is not to be used
with above ground pools or with in-ground pools greater than 90,000 litres.
The unit provides a linecord for input power and a receptacle for the filter pump. The SAS-AU will
turn the pump on/off based on timer settings and produce chlorine only when the pump is running.
This SAS-AU model is designed for use with 40mm or 50mm pool plumbing and must be installed
by a qualified installer. The Cell Vessel must be glued into the pool's plumbing system.
The Salt & Swim requires a low concentration of salt (sodium chloride) in the pool water. It auto-
matically sanitises your pool by converting the salt into free chlorine which kills bacteria and algae
in the water. Chlorine will revert back to sodium chloride after killing bacteria. These reactions
will continuously recycle virtually eliminating the need to add sanitising chemicals to your pool.
The Salt & Swim can handle the purification needs of most residential swimming pools up to 90,000
litres. This unique low cost chlorine generator uses a replaceable electrolytic Cell (SAS-CELL)
that is designed to produce 90Kg of 100% available chlorine over its lifetime.
Note that the actual amount of chlorination required to properly sanitise a pool varies due to bather
load, rainfall, temperature, and the pool's cleanliness.
NOTE: Before installing this product as part of a saline water purification system in a pool or
spa using natural stone for coping or for immediately adjacent patios/decking, a qualified stone
installation specialist should be consulted regarding the appropriate type, installation, sealant (if
any) and maintenance of stone used around a saline pool with electronic chlorine generator in
your particular location and circumstances.
NOTE: The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in arid
regions where pool water is subject to excessive evaporation and is not commonly diluted with
fresh water. Dry acid can cause a buildup of by-products that can damage your chlorinator Cell.

Installation
Remove power to the pool filter pump before starting this installation. Installation must be performed
in accordance with local codes and AS/NZS 3000 Wiring Rules. The Control Box must be mounted a
minimum of 3.5m horizontal distance (or more, if local codes require) from the pool, within 2 metres
from a RCD protected outlet, and within 4.5 metres from where the Cell will be installed. Take care
to protect the Cell Cap connector pins while handling the Salt & Swim unit during installation. If the
supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly quali-
fied persons in order to avoid a hazard.
Preparing Pool Water
To prepare the pool water for Salt & Swim operation, the pool's chemistry must be balanced and salt
must be added. This must be done BEFORE activating the Salt & Swim. Some adjustments to your
pool chemistry may take several hours, so start the procedure well before you intend to operate the
Salt and Swim.
To prepare your pool water, follow the instructions on the included Pool Chemistry Quick Start Guide
and refer to page 8 of this manual.
Adding Salt: Add salt several hours or, if possible, 1 day prior to operating the Salt & Swim. Take
care not to exceed the recommended salt level. Measure salt 6-8 hours after adding to the pool.
NOTE: If the pool does not have new water, add 1 litre of metal remover and 1 litre of non-copper
based algaecide to the pool, per manufacturer's instructions. This ensures a quick, troublefree
transfer to the Salt & Swim system.
Salt & Swim Installation
Follow the step by step instructions located on the Installation Quick Start Guide. Refer to the following
sections for more detailed information.

Mounting the Salt & Swim Control Box
The Salt & Swim is contained in a raintight enclosure that is suitable for outdoor mounting. The Control
Box must be mounted a minimum of 3.5 metres horizontal distance (or more, if local codes require)
from the pool, within 2m from a RCD protected outlet, and within 4.5m from where the Cell is installed.
The Control Box is designed to mount vertically on a flat surface with the cables facing downward.
Because the enclosure also acts as a heat sink (disperses heat from inside the box), it is important not to
block the four sides of the Control Box. Do not mount Salt & Swim inside a panel or tightly enclosed area.
Before securing the Control Box to the intended location, make sure that the power cord will reach
the RCD protected outlet and that the Cell cable will reach the location where the Cell Vessel will be
installed. Refer to the diagram below.
Plumbing
The Cell Vessel is designed to install in 40mm or 50mm PVC pool plumbing only. The Cell Vessel
must be installed on a 350mm run of straight pipe at the end of the return piping just before the water
returns to the pool. All pool equipment should be upstream from the Cell Vessel. It must be located
within 4.5m of where the Control Box is mounted. Also, there must be enough clearance to insert and
remove the Cell from the Vessel after the Vessel is installed.

A minimum 200mm opening must be cut in the pool's plumbing to accept the Cell Vessel for 50mm
plumbing or more if using the 40mm reducers to suit 40mm plumbing. With power removed to the
pump and water drained from the pool plumbing, cut the pipe at the desired location.
After gluing the Cell Unions on to the cut pipe, position the Vessel in a manner where the Cell can be
easily inserted and removed. Secure the Vessel by handtightening the Unions.

Connect and Fasten Cell Cap
Slip the Cell Cap through the Retaining Nut as shown below. Plug the Cell Cap into the Cell and
secure with the Retaining Nut. Run pump for 5 minutes and check for leaks.
Bonding
Pool bonding or "equipotential bonding" ensures that all pool components around the pool are at
the same electrical potential. If bonding is required at your location (see local codes and AS/NZS
3000 Wiring Rules), a bonding lug is provided at the bottom of the Salt & Swim enclosure. Run an
eight gauge (8 AWG) solid copper wire from the bonding lug to your pool's existing bonding loop.

Filter Pump Connection
The filter pump plugs into the SASAU and is controlled based on schedule settings. Locate the
receptacle on the underside of the Salt & Swim enclosure. Note that the rating for this output is 240
VAC, 50hz, 9A. Ensure that your pump does not exceed the rating.
Flow Switch Calibration Procedure
IMPORTANT: Before going any further, the pool water must be balanced and salt must be added to
your pool. If this has not already been done, refer to "Water Chemistry" section of this manual for
information on how to prepare your pool water for Salt & Swim operation.
At start-up, or when a new Cell is installed, the Salt & Swim will run a Flow Switch Calibration
procedure to ensure that the Cell's flow switch is properly initialised. This will occur just once when a
new Cell is installed. After the flow switch is initialised, the Salt & Swim will not perform this
procedure again until the Cell is replaced. The Flow Switch Calibration procedure will require the
user to cycle the pump on and off. Follow the instructions below:
1. Plug the pump into the Salt & Swim.
2. Plug the Salt & Swim's linecord into a Residual Current Device (RCD) safety outlet or an outlet
protected by an RCD. Follow local and AS/NZS 3000 Wiring Rules.
After being powered on for the first time, the Salt & Swim will run a diagnostic routine which can
take up to 30 seconds. During this time, various LEDs will turn on and off. When finished, the
Salt & Swim will display a blinking LOW WATER FLOW LED and a solid GENERATOR RESTING
LED. Keep the Salt & Swim powered for the remainder of this procedure and go to Step 3.
3. Manually turn the filter pump ON using the RUN/STOP button (see page 13). Make sure that full
flow is achieved (no air in the system) and run the pump for at least 15 seconds.
4. Turn the filter pump OFF.
5. The Salt & Swim should now display a solid LOW WATER FLOW and a solid GENERATOR RESTING
LED. The Flow Switch Calibration procedure is complete. You can now turn on your filter pump
and begin normal operation.
If the LOW WATER FLOW LED is still blinking after performing this procedure, refer to the Troubleshoot-
ing section of this manual.

Water Chemistry
The table below summarises the levels that are recommended. It is important to maintain these
levels in order to prevent corrosion or scaling and to ensure maximum performance from your Salt &
Swim chlorine generator. Have your water tested or use pool water test strips. Your Authorised Salt
& Swim Dealer or most pool stores can provide you with the chemicals and procedures to adjust the
water chemistry as well.
Note that pool water emanating from wells and municipal water supplies, along with the introduction
of environmental contaminants, can contain chemistries that are deleterious to the life expectancy
of the Cell.
Saturation index
The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the
pool water "balance". Your water is properly balanced if the Si is 0 ±.2. If the Si is below -0.2, the
water is corrosive and plaster pool walls will be dissolved into the water. If the Si is above +0.2,
scaling and staining will occur. Use the chart below to determine the saturation index.
