The temperature should be approximately 50°C.
Alfa Laval recommends that the primary inlet temperature is at least 10º higher than
the tap water temperature.
NOTE : Make sure that no cold water is mixed with the hot water while making this
adjustment.
Seal the hot water valve with the provided strap.
