Maximum Heigth Difference; Limits Of Use - iDM AERO SLM 3-11 Technical Documentation Installation Instructions

If the height diff erence between the indoor- and outdoor unit is lower than 5 m no oil elevation arc must be
installed before the inclination. In case of a higher height diff erence, the installation must be done after 5 m.
The oil elevation arc must be installed by a certifi cated service technician. Whether the indoor- or the outdoor
unit is higher, does not matter. The maximum height diff erence between indoor- and outdoor unit is 10 m.
Height diff erence lower than 5 m:
<5 m
3 . 16. Limi ts of u se
The heating of other fl uids as heating water is not permitted with the AERO SLM 3-11 and AERO SLM 6-17 (for
heating water quality, see page 44). Heat pumps are by nature subjects to limits of use regarding of pressure
and temperature (see diagram). It is not permissible to operate the AERO SLM 3-11 and AERO SLM 6-17
outside these limits.
Note:
The following safety devices are included to protect the heat pump against faults:
- High pressure presostat
- Maximum fl ow temperature limitation with automatic reset via the Navigator control
- Starting current limiter via inverter technology and performance adjustment
The maximum heat pump fl ow temperature is the highest temperature that the heat pump
can produce (depending on the heat source temperature) and is then switched off at this
value. Due to the hydraulic spread over the heat pump and the control-related switching hys-
teresis, it is not possible to reach this temperature in the heating circuit or in the water heater.
The maximum possible management temperature depends on the hydraulic design and the confi gu-
ration, and is at least 5 K below the maximum heat pump fl ow temperature.
