3Installation

The installation of the WATERMAID® chlorinator should be carried out by a suitably qualified person in

accordance with the Australian wiring rules AS/NZS 3000 The WATERMAID® power supply should be located

within the correct pool zone in accordance with AS/NZS 3000 and connected to the mains supply via an outlet

that is protected by a residual current device (RCD) with a rating that does not exceed 30mA The power

outlet should have a degree of protection suitable for the pool zone Ensure that equipotential bonding of all

parts of the pool installation is carried out

The US and Canadian models require a qualified electrician to hard wire the chlorinator to run in conjunction

with the pump

Incorrect installation may result in failure and may also void warranty

3.1 Cell Installation

The cell must be installed so that ALL the water from the filter passes through the cell BEFORE any diversions

or breakouts to devices such as dual outlets, spa lines and pressure type cleaners

If a heater has been installed, ensure the cell is installed at least 1 5 metres away from the heater

Type P pressure cement must be used for all plumbing Allow 24 hours for the pressure cement to dry

The pressure in the cell must not exceed 150kPa and the water temperature must not exceed 45°C

If a variable speed pump has been installed, ensure there is adequate water flow through the cell at all times

The WATERMAID® WM44 cell has been supplied with plumbing to suit either 40 or 50 mm pool pipe and a

'Removal Tool' for ease of cell union nut removal

See diagram below for correct installation

WARNING: Improper installation or operating the WATERMAID® electrolytic chlorinator model WM44

without adequate water flow through the cell can cause a build up of flammable gases, which can result in

FIRE or EXPLOSION.

3.2 Power Supply Installation

If the WM44 is to replace an older model WATERMAID® chlorinator (purchased after 1994), installation

should be as simple as lifting the old power supply (upwards) off the wall bracket and placing the new WM44

on the existing bracket There is no need to install a new bracket unless the existing one has deteriorated

For all other installations, the stainless steel wall bracket (supplied) will need to be installed A firm surface

able to carry up to 15 kg is required, such as timber, brick or concrete The bracket design is simple and only

requires two (2) stainless steel screws (supplied) Please note: masonry plugs are required for brick/concrete

installations

this feature enabled, the pump will turn off automatically should a water flow issue be detected The pump

protection feature is designed to attempt restarts and then shut down if the water flow fault cannot be

resolved

Pump protection is a last line of defence only It is extremely important that the pool's skimmer baskets are

emptied regularly, no valves are left in the closed position, and other periodic maintenance is carried out

regularly In some pool installations, pump protection may not be advantageous, in which case it can be

turned off (the factory set default is "OFF") The WATERMAID® WM44 cell must be installed as per the

instructions set out in this handbook to maximise the effectiveness of the pump protection feature

There are three adjustable values that can be set within the pump protection menu as follows;

•Max dry runs (mins) – This is the number of minutes (between 1 and 9) that the WM44 will provide

power to the pump after an interruption to the water-flow is detected The factory default for this

setting is 3 minutes

•Retry after (mins) – This is the number of minutes (between 5 and 30) that the WM44 will wait before

reapplying power to the pump socket after an interruption to the water-flow is detected The factory

default for this setting is 5 minutes

Watermaid Pty Ltd

Version 20170223

•Max retries – This is the maximum number of times (between 0 and 4) that the WM44 will attempt to

apply power to the pump socket after an interruption to water-flow is detected The factory default

for this setting is 2
