Bio-Origin -70 °C Antifreeze

Star brite Bio-Origin -70 °C Antifreeze is a natural alternative to traditional antifreeze, providing freeze protection down to -70 °C for drinking water systems and engines during winter storage. This product is safer for humans, animals, and the environment, and is ideal for use in systems such as hydronic and radiant heating, including radiators, solar heating, underfloor heating, and boilers. It provides superior lubrication for gaskets, valves, pumps, and seals, and contains powerful corrosion inhibitors. Safe for copper, brass, and all types of plastics, this antifreeze is perfect for boats, campers, caravans, vacation homes, and swimming pools.

1. Drain the entire water system as thoroughly as possible. Open the hot and cold water taps and all other drainage points. Use compressed air to blow out as much water as possible from the system. 2. Drain the hot water tank. Leave the vent valve open after draining. Install a bypass for the hot water tank by disconnecting the inlet and outlet pipes and connecting them using fittings or a hose and hose clamps. 3. Add Bio-Origin -70 °C Antifreeze undiluted to the drinking water system. 4. Pressurize the system and activate the water-demanding pump. 5. Open all faucets, starting with the furthest one, and allow the antifreeze to flow until the colored fluid appears. Then close the drain point. 6. Repeat step 5 at each freshwater drainage point. 7. Flush the toilet several times to ensure it is fully drained. Note: Make sure the holding tank is completely drained. 8. Activate the pump valve several times to ensure that the waste system contains enough antifreeze for protection.
