HARPIC FLUSHMATIC CISTERN SYSTEM Harpic Flushmatic works from within your cistern to release a measured dosage of our powerful blue foaming detergent with every flush. This toilet cleaner distributes detergent across the bowl to help you maintain a clean and deodorised toilet and prevent the build up of stains. HOW TO USE 1. Remove cistern cover. 2. Carefully remove Harpic Flushmatic from the box. Take care as the powder residue may spill. Attach strap to bottle. 3. Place Harpic Flushmatic in the cistern in an upright position. Do not submerge under water. Place bottle clear of water inlet pipe and working parts. Hang part of the strap outside the cistern (see diagram). 4. Return the cistern cover and ensure strap holds Freshmatic in place. 5. Replace when the colour disappears. 6. To dispose of bottle, fully empty remaining liquid in unit into cistern prior to removal.
