How to Use: · Add 3 x Power Crystals Cleaner into the system for every 159 litres of system water via the system filter, or other access point. Pre-dilute in warm water if necessary. · Open all radiators or underfloor heating loops to ensure full circulation. · For rapid cleaning, circulate for a minimum of 2 hours, then treat each loop individually for 5 to 10 minutes. For slow cleaning, allow cleaner to circulate for 1 to 4 weeks. · Drain the system and rinse with clear water until the rinse water runs free of any blue colour. · Refill the system with clean water and protect it by adding the correct dose of BWT Power Crystals cleaner.
