1.3 Safety notice and warnings
Read these instructions carefully before installation, commissioning, operation, or
maintenance of the device. The given instructions must be followed. Throughout this
manual, the following symbols are used to point out very important information:
Use special caution. The DANGER symbol indicates an immediate
hazard that will result in serious injury or death.
M8006 2314EN 3 (59)
Use special caution. The WARNING symbol indicates a hazard that
may result in serious injury or death.
Use caution. The CAUTION symbol indicates a hazard that may result
in an injury.
Pay attention. The NOTICE symbol indicates a risk of damage to the
equipment, components, or surroundings.
The ‘i’ (info) symbol indicates important information as well as useful
tips and hints.
Keep these instructions as well as the electrical diagrams available near the device.
Installation, commissioning, or service of the appliance is to be carried
out by authorized and trained personnel only, adhering to all local
regulations and requirements.
Wear proper personal protective equipment, such as protective
footwear, gloves, and safety goggles when necessary.
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).
4 (59) M8006 2314EN
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.
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.
Lifting and handling
The weight of the unit presents a crush hazard. Use safe work methods
when lifting and handling the unit.
During lifting, do not walk or work under the heat pump or any other
suspended load.
Do not lift or move the unit with the domestic hot water tank filled.
Tablet
Use the tablet provided with the unit only for operating the heat pump.
Using the tablet 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.
Other considerations
To avoid slipping, keep floor surfaces dry, and seal off or report any
leaks that you detect.
M8006 2314EN 5 (59)
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.
The compressor unit can be tilted up to 45 degrees from horizontal.
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.
Lifting units equipped with a built-in DHW tank
Do not lift or move the unit with the domestic hot water tank filled.
Do not lift the heat pump from the bottom of the compressor unit. Lift the
unit by the frame.
● 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.
● If you need to tilt the heat pump beyond 45 degrees, remove the compressor unit.
