11.4. Emptying the water heater
It is advisable to drain the water from inside the water heater if it should remain unused for a certain
period of time, especially at low temperatures. It is sufficient to disconnect the water supply inlet con-
nection. Alternatively, during the installation stage of the system, it is advisable to install a drain trap
with a connection to a hose. It is important to empty the system in order to avoid freezing water if the
product is unused for a period of time.
