IMPORTANT: 

Installation must comply with existing State or Local Plumbing codes. Some Plumbing 

Codes require installation of this filter system to be carried out by a Licensed Plumber.

In some areas, the water pressure may exceed the 

system’s maximum pressure allowance. If this is 

the case, a pressure limiting valve will be required. Please check with your Lincensed Plumber during 

installation. 

CAUTION: 

The Triple Undersink water filtration system should only be used on water that is  

  

microbiologically safe- that is, water that has been adequately chlorinated or disinfected. Additional 

sterilising equipment will be required for unsafe water.

The Stefani Triple Undersink water filtration system is designed to operate at a maximum pressure of 

862kPa (125psi); minimum pressure of 69kPa (10psi) and at a maximum temperature of 40 degree 

Celsius. Stefani warrants this filter to be free from defects in material and workmanship for a period 

of two years * from the date of purchase (* Warranty period excludes filter cartridges which are 

consumable items).

RECOMMENDATION: 

If the undersink water filtration system has not been used for 2 or more days, 

you will need to flush 5 to 10 litres of water through the system before using the water. If the unit is to 

be left unused for more than 2 days, the water supply valve must be turned off.

Slower flow rate gives longer contact times for better contaminant reduction. 

To maintain a high level of performance and protection provided by the STEFANI water filtration 

system, use only STEFANI replacement filter cartridges.

HELPFUL HINT: 

The life and performance of filter cartridges may vary, depending on volume and 

quality of water being filtered. An indication, that your filter cartridges may need replacing is the 

reduced volume or flow from filter faucet, or the return of offensive taste and/or odour to filtered water.

We recommend you continue to check for leaks for a day after installation.

Please note our warranty requires proof of installation by a licensed plumber including  comfirmation 

of water pressure testing and results.
