Water Piping

WARNING
• Install water pipes according to the regulations of respective countries.
• Install water pipes in a freeze-free place.
• Make sure that water pipes have sufficient pressure resistance
(The setting value of the pressure relief valve is 0.3 MPa).
CAUTION
• Do not use zinc plated water pipes. When steel pipes are used, insulate both ends of the pipes.
• The water to be used must meet the water quality standards specified in EN directive 98/83 EC.
Water Circuit
• Install a strainer with 30 to 40 meshes (procure locally) at
the water inlet of the Hydro Unit.
• Install drain cocks (procure locally) for water charge and
discharge at the lower part of the Hydro Unit.
• Make the piping route a closed circuit. (An open circuit may
