This requires:
- either removing water from the pump, the regulator, the hoses, the filters and other
elements…;
- either storing the device in a warm space;
- or using an agent against freezing (antifreeze).
13.2.10 Procedure of protecting the sprayer with anti-freezing agent
After you have finished cleaning the spraying device, completely empty the tank and pour at
least 10 litres of antifreeze agent (a mixture of water and antifreeze) and turn on the pump.
Open all valves on the regulator in order the antifreeze agent can reach all hoses and nozzles.
At the end, empty the remaining agent from the tank in a suitable container and let the pump
operate for few more minutes in order to pump the remaining agent into the tank.
WARNING: Make sure that the antifreeze agent is poured into appropriate
containers! Do not discard antifreeze agents in nature!
Protect the manometer against freezing by unscrewing it from the regulator and storing it in a
warm room. The manometer must be stored in an upright position or the glycerine filling can
flow out!
