as the pipes may be hot and could burn your hand. To avoid injury,
give the piping time to return to normal temperature or be sure to
wear protective gloves.

the unit.
(*) The models have a freeze prevention function that uses the heat
pump and back up heater to keep the water system safe from
freezing in all conditions. If there is an accidental or intentional
power shutdown, using glycol is recommended (Refer to 9.3
