1.2 Product description
RE 05 heat pumps
RE 05 heat pumps come in two configurations: RE 28–48 heat pumps have a single
compressor unit, while RE 56–96 heat pumps have two compressor units. All RE heat
pumps include a control cabinet. The standard position of the control cabinet is on the
unit's left side, but it can be moved to the right side if needed.
RE 28–48 models
By default, the unit’s automation system has been configured for one domestic hot
water tank, one buffer tank for a heating circuit, and one heating circuit controlled by
a three-way valve. The automation system supports numerous other connections,
systems and accessories. Alternative system configurations are presented in separate
technical manuals for the automation system.
RE 56–96 models
The heat pump includes two compressor units, which can be used independently or
they can be joined together. The automation system has a separate controller and
separate electrical connections for each unit. If the units are used separately, they
operate independently of each other.
In standard two-unit deliveries, the units’ automation systems have been connected
for joint use (in a cascade configuration). In cascade systems, one of the heat pump
controllers operates as the master and controls the entire system, while the other, the
slave controller, operates under the master controller. The upper unit is the master unit
and the lower unit the slave unit.

1.4 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 three symbols are used to point out very important information:
Be careful. The DANGER symbol indicates a possible danger of bodily
harm or lethal injury.
Pay attention. The CAUTION sign indicates a possible danger of
damage to the device, components or surroundings.
Note indicates tips, hints, and other essential information.
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 hearing protection and personal protective equipment,
such as protective footwear, gloves, and safety goggles when
necessary.
4 (74) M8009 2147EN
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.
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.
Other considerations
To avoid slipping, keep floor surfaces dry, and seal off or report any
leaks that you detect.
M8009 2147EN 5 (74)
1.5 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.
Do not tilt the 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.
Lifting
Lift and move the unit with a hand pallet truck or forklift.
● Lift and move the unit only so that both forks of the lifting device extend under the
whole unit.
● Keep the exterior panels of the compressor unit closed when lifting and moving the
heat pump.
● Do not lift the unit from under the control cabinet.
● Do not use the user interfaces as support points when lifting the unit.
Two-unit heat pumps:
Lift the tower consisting of two units only from below the lower unit.
