rods or ground wires for telephone wires.
• Turn off the main power supply switch or breaker before
attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause
electric shock.
Use an exclusive power circuit for the Air to Water Heat Pump. Use
the rated voltage.
• Connect the system interconnection wire correctly.
If the system interconnection wire is connected in a wrong way,
electric parts may be damaged.
• When moving the Air to Water Heat Pump for the installation into
another place, be very careful not to enter any gaseous matter

If air or any other gas is mixed in the refrigerant, the gas pressure
in the refrigeration cycle becomes abnormally high and it may
resultingly causes pipe burst and injuries on persons.
