2.1 General safety precautions
Risk of personal injury! Children are not permitted to play with the product.
As the water temperature in DHP-H Opti Pro/DHP-H Opti Pro + and DHP-L Opti Pro/DHP-L Opti Pro + be-
comes hot (up to 95°C), 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.
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.
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.
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.
The heat pump must be located in a frost-free environment!
The heat pump must be placed in an area with a floor drain.
The heat pump must be located on a stable base. The floor must be able to support the gross weight of the
heat pump with filled hot water tank (see Technical data).
To prevent leaks, ensure that there are no stresses in the connecting pipes!
It is important that the heating system is bled after installation.
Bleed valves must be installed where necessary.
The hot water tank must be equipped with an approved safety valve.
Heating systems with closed expansion tanks must also be supplied with approved pressure gauges and safe-
ty valves.
