Bosch HP270-2 - Guideline for Expected Temperatures in Refrigerant Circuit

Page 28 from 56 6-720-821-364 SM HP270 – 250 - 200 2016/12 en
The aim of following data is to help technician detects if behaviour and heat up time is normal depending of
conditions (thermal power calculation was considering a flow rate of 3.5 l/min (speed 1))
