Notes:

①

The above table lists specifications of the air source water heater series product for static heat up. The

product standard is EN16147-2011, (EU) No 814/2013, EN 12102-2008.

②

Conditions for testing heating capacity of the unit: outdoor ambient temperature: 20°C DB/15°C WB;

Initial/ending water temperature in the water tank: 15°C/55°C.

③

For units with a water tank equipped with an electrical heater, that is, the model of which includes

― D ‖,

both the heat pump and electrical heater are started for heat up under low ambient temperature or rapid

mode.

④

If the product specification changes with product improvement, refer to the parameter specified on the

nameplate.
