Steps
- If the machine must not run meanwhile, close the upstream water valve and switch the machine off: with the handle open, water can bypass the cartridge. Optional
From the manual: “close water intake and switch off power supply to the terminal equipment”
- Swing the locking handle on the filter head open.
From the manual: “Open locking handle 2”
- Press the flush valve to let the pressure out of the system.
From the manual: “Activate the flush valve 8 and depressurise the system.”
- Lift the spent cartridge out of the head, minding its weight; tilting it 90 degrees in the wall bracket makes this easier.
From the manual: “Remove exhausted filter cartridge 6 from the filter head”
- Look at the head, hoses and seals while the cartridge is out; replace anything faulty and clean anything dirty.
From the manual: “examine all remaining parts carefully! Faulty parts must be replaced and contaminated parts should be cleaned!”
- Find your carbonate hardness (Quell ST) or total hardness (Finest) with the BRITA test kit, or ask your water supplier. Only when: at installation, or if your water has changed
From the manual: “Alternatively, your local water supplier will be able to provide information on the local water hardness.”
- For a Quell ST on the 0-70 % head, read the bypass and capacity in litres for that hardness off the coffee/espresso column of BRITA's table. Only when: Quell ST cartridges
From the manual: “Table of bypasses and capacities PURITY C Quell ST”
- Turn the bypass dial on the head to the value you looked up (it leaves the factory at 30 %). Only when: Quell ST on a 0-70 % variable head
From the manual: “Then turn the by-pass setting 11 to the identified value.”
- Pull up the tab on the new cartridge's protective cap and take the cap off.
From the manual: “Pull the flap of the protective cap 7 upwards and remove the protective cap.”
- Make sure both O-rings sit flush and tight.
From the manual: “Check O-rings 10 for correct fit (flush, tight).”
- Write the next change date in the date box on the cartridge label.
From the manual: “Note the next exchange date in the date field on the filter cartridge”
- With the handle still open, push the cartridge straight up into the head, held vertical.
From the manual: “Insert the filter cartridge 6 in the filter head 1 in a vertical position.”
- Turn the locking handle closed until it clicks into place.
From the manual: “Turn the locking handle 2 until you feel it engage.”
- Open the water supply again and switch the machine back on.
From the manual: “Open the water intake and switch on the terminal equipment’s power supply.”
- Hold a container under the flush hose to catch what comes out.
From the manual: “catch water emerging from the flush hose 9 in an appropriate container”
- Open the flush valve and run water off until it is clear and bubble-free, and at least twice the empty cartridge volume (C50 1 l, C150 1.9 l, C300 2.9 l). Repeat until the water runs clear and bubble-free
From the manual: “flush the filter system until the filtered water runs clear and without bubbles”
- Check every connection for leaks.
From the manual: “Check system for any leaks.”
