2 Important information/Safety regulation
2.1 General safety precautions
Warning Risk of personal injury! Children are not permitted to play with the product.
Warning As the water temperature in DHP-H Opti Pro and DHP-L Opti Pro becomes extremely hot, a mixer valve must
be installed between the cold water and hot water pipes to ensure a lower domestic hot water temperature.
Alternatively the maximum hot water temperature must be reduced in the Service menu.
Warning Danfoss SP (1-phase) heat pumps have a factory installed safety valve for temperature and pressure, (10 bar
90-95°C), in accordance with the requirements in Great Britain. This valve is located in the water tank and may
not be used for any purpose other than connecting the outlet pipe. Also note that for heat pump DHP-H Opti
Pro SP and DHP-L Opti Pro SP it is imperative that the hot water temperature is changed from default setting
95°C to 85°C.
Caution The heat pump must be installed by authorised installation engineers and the installation must follow the
applicable local rules and regulations as well as these installation instructions.
Caution This product is not intended for persons (including children) with reduced physical, sensory or psychological
capacity, or who do not have knowledge or experience, unless supervised or they have received instructions
on how the apparatus functions from a safety qualified person.
Caution The heat pump must be located in a frost-free environment!
Caution The heat pump must be placed in an area with a floor drain.
