1.3 Safety notice and warnings
Any maintenance and service procedures described in this manual should be
performed by competent and appropriately trained maintenance personnel only. The
unit contains no user-serviceable parts.
M8006 2123EN 3 (54)
Electrical safety
Once powered on, some of the unit’s components carry a hazardous
voltage. Always pay attention to electrical safety when working with or
near electrical components.
Before any maintenance or servicing, switch off electricity using the
main switch and ensure that there is no voltage present in the unit’s
components.
Refrigerant
Refrigerant leaking from an open or broken circuit may cause
asphyxiation, severe frost damage, arrhythmia, or neurological
symptoms. If you suspect a refrigerant leak, leave the area immediately,
and seek fresh air. Help and warn others.
The unit includes a hermetically sealed refrigerant circuit filled with refrigerant R-410A.
Refrigerant R-410A is a mixture of two refrigerants: HFC-32 (R-32, difluoromethane)
and HFC-125 (R-125, pentafluoroethane).
Refrigerant R-410A is a fluorinated greenhouse gas and, consequently, subject to the
EU F-gas Regulation. Please recover the refrigerant as required by law, and transfer
the refrigerant for recycling or disposal as required by applicable laws, rules and
regulations.
The refrigerant is heavier than air. The refrigerant may accumulate in enclosed spaces,
especially at or below the floor level (for example, in basements). Ventilate the spaces
by opening the space’s doors and windows from the outside. Use fans, if necessary.
Do not enter any space where you suspect there to be leaked refrigerant present.
Lifting and handling
The weight of the unit presents a crush hazard. Use safe work methods
when lifting and handling the unit.
Safety devices
Do not bypass, disable, or damage any of the unit’s pressure switches or other
safeguards with tools, by accessing the system’s software, or by any other means.
Bypassing the unit’s safeguards may lead to equipment failure, damage to property or
injury to people.
Wireless touch screen
Use the wireless touch screen provided with the unit only for operating the unit’s
automation system. Using the touch screen for any other purpose may cause
slowdowns or interference in the use of the unit’s automation system, or prevent the
system from being used altogether.

1.4 Transportation and storage
Storage
Store the unit upright in a warm, dry place. Protect the device against water and dust.
Do not stack goods on the unit.
Transportation
Transport the unit upright and protected against water and dust. Do not stack goods
on the unit. Use only safe lifting and handling methods when moving or lifting the
unit. After lifting, lower the unit carefully down onto the floor. Hard impacts can cause
equipment damage.
When lifting the unit, grab the unit by the frame. Do not lift the heat pump from the
bottom of the compressor unit.
● The unit’s exterior panels may be removed to make it easier to carry and move the
unit.
● The unit can be carried short distances by the side bars.
● If necessary, the compressor unit can be detached from the frame of the heat pump
before carrying or tilting the unit.*
● Do not lift or move the unit with the domestic hot water tank filled.*
*Applicable to heat pumps with an integrated DHW tank.
The compressor unit can be tilted up to 45 degrees from horizontal. If you need to tilt
the heat pump beyond 45 degrees, remove the compressor unit.
● If the unit is tilted beyond 45 degrees, the compressor may not receive proper
lubrication at startup. As a result, the compressor may become damaged.
● If the unit has been accidentally tilted beyond 45 degrees, leave the unit in vertical
position for at least three hours before starting the compressor.
