• Please engage a licensed water circuit installer to install this water
circuit.
• This water circuit must comply with relevant European and national
regulations (including EN61770), and local building regulation codes.
• Ensure the components installed in the water circuit could withstand
water pressure during operation.
• Do not use worn out tube or detachable hose-set.
• Do not apply excessive force to pipes that may damage the pipes.
• Choose proper sealer which can withstand the pressures and
temperatures of the system.
• Make sure to use two spanners to tighten the connection. Further tighten
the nuts with torque wrench in specified torque as stated in the table.
• Cover the pipe end to prevent dirt and dust when inserting it through
a wall.
• If non-brass metallic piping is used for installation, make sure to insulate
the pipes to prevent galvanic corrosion.

Do not over tighten, over tightening cause water leakage.
• Make sure to insulate the water circuit pipes to prevent reduction of
heating capacity.
• After installation, check the water leakage condition in connection area
during test run.
• Failure to connect the tube appropriately might cause the Indoor Unit
malfunction.
• Protection From Frost:
If the Indoor Unit is being exposed to frost while power supply failure or pump
operating failure, drain the system. When water is idle inside the system,
freezing up is very likely to happen which could damage the system. Make
sure the power supply is turned off before draining. Backup heater 9 may
be damaged under dry heating.
