Installing 3way Valve
• Flow direction :
- Water should flow from water outlet of the unit to DHW tank water inlet when DHW tank heating is
selected.
- To verify the flow direction, check temperature at the water outlet of the unit and water inlet of DHW tank.
- If correctly wired, these temperatures should be almost equivalent if thermal insulation of water pipe is well
performed.
• Noise or water pipe vibration while 3way valve operation
- Due to surging effect or cavitation effect, noise or water pipe vibration can be occurred while 3way valve is
operating.
- In that case, check followings :
• Is water circuit (both under floor water loop and DHW tank loop) fully charged? If not, additional water
charging is required.
• Fast valve operation yields noise and vibration. Appropriated valve operating time is 60~90 seconds.
Installing 2way Valve
• Flow direction :
- Water should not flow into under floor loop in cooling mode.
- To verify the flow direction, check temperature at the water inlet of the under floor loop.
- If correctly wired, this temperatures should not be approached to 6°C(42°F) in cooling mode.
Freezing protection
Set the Dip SW and short key to Anti Freeze mode only after the addition of brine (Anti-freeze).
Or else the product may get damage due to freezing and bursting.
