14. Install a pressure relief valve that meets or exceeds the design water pressure (10).
The pressure relief valve helps to prevent Hydro Kit or water circuit damage if the pressure increases inside the water circuit system.
15. Install insulation to the water circuit system to prevent condensation. Use proper size insulation as outlined by insulation manufacturer
and by the design engineer.
