WHOLE-HOUSE FILTRATION + SCALE CONTROL + UV

Triple 20 Antiscale Stainless Enclosure & UV Protection System

The Triple 20 Antiscale Stainless Enclosure & UV Protection System is a multi-stage whole-house water treatment package combining three large 20-inch filtration stages, a dedicated scale-control stage, a stainless steel enclosure and ultraviolet treatment.

It is designed for properties that require more than basic sediment filtration and want several treatment functions brought together in one organised installation.

The exact cartridge combination, UV specification, flow capability and installation requirements depend on the configuration selected. These details should be confirmed against the components supplied with the system before installation or replacement parts are ordered.

Quick answer: this is a triple 20-inch whole-house filtration system with scale-control and UV treatment, housed within a stainless steel enclosure. It is intended to combine sediment filtration, additional water-treatment stages, scale-management and ultraviolet treatment in one installation. The exact filtration ratings, UV specification and service intervals depend on the cartridges and UV components supplied with your selected configuration.
SYSTEM AT A GLANCE

Triple 20 System Overview

3 Stages 20-Inch Filtration
```
Antiscale Scale-Control Stage
UV Ultraviolet Treatment
Stainless Protective Enclosure
```
WHAT IT DOES

Multiple Water-Treatment Functions in One System

The Triple 20 configuration is designed to bring several treatment stages together rather than relying on a single cartridge.

Sediment Filtration

One or more stages can be configured to reduce suspended dirt, rust, sand, silt and other particulate material.

```

Carbon Treatment

Where a compatible carbon cartridge is included, the system can provide chlorine, unwanted taste and odour reduction.

Scale Control

The antiscale stage is intended to help manage scale formation within compatible plumbing and appliance applications.

UV Treatment

The ultraviolet stage provides an additional treatment step after cartridge filtration where the selected UV configuration is suitable for the incoming water.

Whole-House Application

The system is designed to treat water at a central point before it is distributed through applicable household plumbing.

Enclosed Installation

The filtration equipment is arranged within a stainless steel enclosure for a more organised whole-house installation.

```
THREE LARGE-FORMAT FILTER STAGES

Why Use a Triple 20-Inch Configuration?

A triple-stage system allows different filtration media to be used for different jobs.

For example, the first stage can be used for sediment pre-filtration, a second stage can provide carbon or other treatment, and a third stage can provide scale-control or finer filtration depending on the selected package.

This staged approach also allows the UV unit to receive pre-filtered water rather than untreated incoming water.

ANTISCALE STAGE

Scale Control Without Describing It as a Water Softener

The antiscale stage is designed to help manage mineral scale formation within compatible plumbing and appliance applications.

It should not automatically be described as a conventional ion-exchange water softener unless the specific media supplied with the system performs that function.

Scale-control and water-softening are not the same treatment process. A scale-control cartridge may help reduce scale formation while leaving naturally occurring calcium and magnesium in the water. Confirm the exact media supplied if hardness removal is required.
UV TREATMENT

Ultraviolet Treatment After Filtration

The UV stage is installed downstream of the cartridge filtration stages so the water reaching the UV chamber has already passed through the applicable pre-filtration.

UV systems depend on adequate water clarity, correct flow, the correct lamp and quartz-sleeve condition, and the UV equipment being operated within its manufacturer specifications.

Do not assume a universal microorganism-reduction percentage. UV dose and treatment performance depend on the exact UV model, flow rate, source-water quality and installation conditions. Follow the specifications for the UV unit supplied with the system.
STAINLESS STEEL ENCLOSURE

An Organised Whole-House Installation

The system uses a stainless steel enclosure to house and organise the filtration components within one installation.

This provides a dedicated mounting arrangement for the large-format filter stages and associated treatment equipment while also presenting the system as one integrated package.

The exact stainless grade, enclosure dimensions and environmental installation requirements should be confirmed from the specification supplied with the selected system configuration.

WHO IS IT FOR?

When a Triple-Stage System May Be Suitable

  • You want whole-house rather than single-tap filtration
  • Your water requires sediment filtration before downstream treatment
  • You want a dedicated scale-control stage
  • You require carbon treatment as part of the selected configuration
  • You want UV treatment after cartridge filtration
  • You prefer large 20-inch filter housings for whole-house applications
  • You want the filtration equipment arranged inside a stainless enclosure
  • You have suitable space, plumbing access and electrical provision for the installation
CHECK BEFORE ORDERING

Confirm Your Water Source & Treatment Requirements

Whole-house filtration should be selected around the incoming water conditions rather than by the number of filter housings alone.

Mains Water

Where chlorine, sediment, scale or unwanted taste and odour are the main concerns, the cartridge combination should be selected accordingly.

```

Rainwater

Rainwater applications may require sediment filtration and UV treatment, with the final configuration selected for the source-water conditions.

Bore Water

Bore water can contain dissolved minerals or other issues that require testing and specialist treatment beyond standard sediment, carbon and UV stages.

```
Do not assume one configuration suits every water source. Iron, manganese, salinity, hardness, colour, turbidity or other source-water conditions may require additional or different treatment.
CONFIGURATION

Exact Cartridge Combination Can Vary

The product name identifies a triple 20-inch system with scale-control and UV treatment, but the exact cartridge media and micron ratings should be confirmed from the selected product configuration.

A typical staged arrangement may include:

Stage 1

Coarse or fine sediment filtration selected for the incoming particulate load.

```

Stage 2

Carbon or other treatment media selected for the required water-treatment function.

Stage 3

Antiscale or other final cartridge stage according to the package ordered.

```

The actual cartridge order supplied with the system should always take priority over a generic example.

INSTALLATION REQUIREMENTS

What the Installation Needs

A triple 20-inch whole-house system is considerably larger than an under-sink filter and needs to be planned around the property.

  • Suitable position on the incoming water line
  • Adequate wall or floor space for the enclosure
  • Clearance for removing 20-inch filter bowls during servicing
  • Accessible upstream water isolation
  • Suitable downstream plumbing arrangement
  • Electrical supply suitable for the UV equipment
  • Protection from unsuitable environmental conditions where required
  • Suitable drainage and service access around the installation area
FLOW & PRESSURE

Sizing the System for the Property

The correct system flow cannot be determined from the words “Triple 20” alone.

Whole-house flow is influenced by the filter cartridges, UV chamber, fittings, pipework, available incoming pressure and the simultaneous demand from showers, taps and appliances.

Confirm flow and pressure before installation. The UV unit must also be sized so the water does not exceed the flow permitted for the required UV treatment performance.
MAINTENANCE

Filter Cartridges, Antiscale Media & UV Components Need Separate Servicing

The entire system should not be assigned one universal maintenance interval because different components can have different replacement requirements.

Sediment Cartridges

Replacement depends on sediment loading, water use and the manufacturer interval for the exact cartridge supplied.

```

Carbon Cartridge

Carbon service life depends on the media capacity, incoming water conditions and total treated water volume.

Antiscale Stage

Replace according to the manufacturer specification for the exact scale-control cartridge or media supplied.

UV Lamp

Replace according to the service interval specified by the UV manufacturer, even if the lamp still visibly illuminates.

Quartz Sleeve

Inspect and clean according to the UV manufacturer instructions so deposits do not obstruct UV transmission.

Housing Seals

Inspect O-rings and sealing surfaces whenever filter housings are opened for cartridge replacement.

```
SERVICE INDICATORS

When the System May Need Attention

  • Water flow has noticeably reduced
  • Sediment cartridges are heavily loaded
  • Unwanted taste or odour begins to return
  • The antiscale cartridge reaches its specified service limit
  • The UV lamp service indicator is due
  • The quartz sleeve requires cleaning
  • Filter housings or connections show signs of leaking
  • Incoming water conditions have materially changed
UV SERVICE SAFETY

UV Maintenance Requires Water & Power Isolation

Servicing the UV section involves both pressurised plumbing and electrical equipment.

Electrical power and water must be correctly isolated before UV servicing. Follow the instructions supplied with the exact UV unit before removing the lamp, quartz sleeve or any electrical component.

The UV lamp and quartz sleeve are glass components and should be handled carefully. The lamp should never be viewed directly while operating outside its normal protective chamber.
