INSTALLING THE WATER CIRCUIT
Water Circuit Components
The water circuit guidelines and diagrams are for illustrative purposes and are to be used for references only; not all components and accessories
local, state, and federal codes.
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.
Circulate or drain out the water completely if the water circuit isn't going to be used for an extensive period. This is to prevent sludge or dirt from set-
tling and damaging the piping or system components.
