The recommended in-use concentration of the product is 0.5%. Fernox HVAC Protector F1 can be introduced into the system via the feed and expansion tank or injected directly into the system via a suitable point (e.g. dosing pot). To ensure speedy dispersion, partly or completely drain down and introduce HVAC Protector F1 whilst refilling. In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used. We recommend untreated systems are thoroughly cleansed and flushed using Fernox HVAC Cleaner F3 before treating with Fernox HVAC Protector F1 as existing debris can damage the installation.
