Data in compliance with Eurovent conditions, summer: indoor 27 °C TS/19 °C TH ‑ outdoor TS 35 °C. Winter: Indoor TS 20 °C, outdoor TS 7 °C / TH 6 °C (TS Dry-bulb thermometer; TH Wet-
bulb thermometer), with vertical ducts, rated air flow and pressure.
Net EER = Net cooling capacity / Total absorbed power (according to Eurovent).
Net COP = Net heating capacity / Total absorbed power (according to Eurovent).
(2) Add the inside motor consumption to find the total calorific capacity.

Circuit breaker with K curve, according to DIN, VDE 0660-104. Section of cables for the power supply line based on copper conductors, 105 °C. The circuit breaker and the section of power
supply cables indicated are for guidance. They should be adjusted based on the requirements of each installation, distance between units, fall in planned voltage and on the application of the
current regulations with respect to the country where the unit is being installed.
