Example of Hydro Unit installation

■ Example of installation for cooling and heating
• When the cooling mode is required, a 2-way valve must be installed to isolate the radiator.
A 2-way valve shoud be installed to isolate the under-floor heating if necessary.
• If the minimum flow rate cannot be secured, install a buffer tank and pump.
Please refer to page 11 for how to check the flow rate.
CAUTION
Please pay attention to the cooling temperature settings, as we cannot guarantee the damages caused by the air
humidity condensation on the radiator or under-floor heating circuit and pipeline surfaces.
