Carefully read the enclosed
instructions and all other ap­plicable documents, particu-
larly the "Safety" section and the warnings.
1.2.2 Risk of death due to explosions and scaldings from brine fluid
The brine fluid ethylene and propylene glycol is extremely flammable, both as liquid and steam. A potentially explosive combination of steam/air may form.
Keep away from heat, sparks,
naked flames and hot sur­faces.
Prevent steam/air mixtures
from forming. Keep brine fluid vessels closed.
Observe the safety data sheet
that accompanies the brine fluid.
1.2.3 Danger due to improper use

1.2.4 Preventing the risk of injury from corrosive brine fluid
The brine fluid ethylene glycol is harmful to health.
Avoid contact with the skin
and eyes.
Always wear gloves and pro-
tective goggles.
Do not inhale or swallow.Observe the safety data sheet
that accompanies the brine fluid.
1.2.5 Preventing the risk of injury due to scalding from hot and cold components
Particularly in the coolant cir­cuit, the components of the heat pump can reach high temperat­ures or extremely low temperat­ures.
Do not touch any uninsulated
pipelines in any part of the heating installation.
Do not remove any casing
sections.
1.2.6 Risk of being scalded by hot drinking water
There is a risk of scalding at the hot water draw-off points if the hot water temperatures are greater than 50 °C. Young children and elderly persons are
particularly at risk, even at lower temperatures.
Select the temperature so
that nobody is at risk.
1.2.7 Risk of death due to lack of safety devices
A lack of safety devices (e.g. expansion relief valve, expan­sion vessel) can lead to poten­tially fatal scalding and other injuries, e.g. due to explosions.
Have your competent person
check that all required isolator devices are present in your heating installation.
1.2.8 Preventing the risk of injury from freezing as a result of touching coolant
The product is delivered with an operational filling of R410A coolant. This is a chlorine-free coolant which does not affect the Earth's ozone layer. R410A is neither a fire hazard nor an explosion risk. Escaping coolant may cause freezing if the exit point is touched.
If coolant escapes, do not
touch any components of the product.
Do not inhale any steam or
gases that escape from the coolant circuit as a result of leaks.
Page 5
Safety 1
0020151761_04 aroTHERM Operating instructions 5
Avoid skin or eye contact with
the coolant.
In the event of skin or eye
contact with the coolant, seek medical advice.
1.2.9 Danger due to changes to the product environment
There is a risk of injury or death to the user or others, or of damage to the product and other property, in the event of changes to the product environment.
Changes must not be made to the following equipment:
The heat pumpThe heat pump environmentThe drain line and expansion
relief valve for the heating water
– The water and electricity sup-
ply lines
– The heat pump's condensate
drain pipework
– The structural conditions that
may affect the operational safety of the product.
1.2.10 Risk of injury and
material damage due to incorrect maintenance or repairs
As a result of unauthorised in­terference or tampering with the product or parts of the system,
the operational safety of the product can no longer be en­sured and the guarantee there­fore becomes void.
Never interfere or tamper with
the product or other parts of the system.
Never try to carry out main-
tenance work or repairs on the product yourself.
Do not damage or remove
any seals on components. Only qualified competent persons and factory service personnel are authorised to make modifications to sealed components.
Have inspection and main-
tenance work carried out by a competent person.
1.2.11 Frost damage due to an unsuitable installation site
Frost poses a risk of damage to the product and the whole heating installation.
You should therefore ensure
that the heating installation always remains in operation during freezing conditions and that all rooms are sufficiently heated.
Even if rooms, or the whole dwelling, are not in use for cer­tain periods, the heating must remain in operation.
Page 6
1 Safety
6 Operating instructions aroTHERM 0020151761_04
Frost protection and monitoring devices are only active while the product is connected to the power supply. The product must be connected to the power supply.
1.2.12 Frost damage caused by insufficient room temperature
If the room temperature is set too low in individual rooms, it cannot be ruled out that sec­tions of the heating installation might be damaged by frost.
If you are going to be away
during a cold period, ensure that the heating installation remains in operation and that the rooms are sufficiently heated.
You must observe the frost
protection instructions.
1.2.13 Frost damage caused by a power cut
During installation, your com­petent person connected your product to the power mains. If the power supply is cut, it is possible that parts of the heat­ing installation may become damaged by frost. If you want to use an emergency power generator to maintain the oper­ational readiness of the product
during a power cut, note the fol­lowing:
Contact your competent per-
son for advice on installing an emergency power generator.
Ensure that the technical val-
ues of this generator (fre­quency, voltage, earthing) match those of the power mains.
1.2.14 Malfunction caused by incorrect system pressure
To avoid operating the system with too little water and thus prevent resulting damage, note the following:
Check the system pressure
of the heating installation at regular intervals.
You must observe the system
pressure instructions.
1.2.15 Malfunction due to incorrect power supply
The power supply must remain within the specified limits so that the product does not malfunc­tion:

6.2 Detecting and rectifying faults
This section shows all of the fault messages that can be rectified without seeking help from the competent person in order to start up the product again.
Remedy (Page 17)
If the product still does not function after the fault has been rectified, contact your
competent person.
Fault Cause Remedy
The product no longer works.
The power supply has been disconnec­ted
Ensure that there has not been a power cut and that the product is correctly connected to the power supply. When the power supply is re­established, the product automatically starts up. If a fault is still present, contact your competent person.
Noises (hissing, knocking, humming)
If the heating demand stops, this may lead to bubbling and whistling noises. These noises are caused by the coolant. When the product starts up or stops, this may lead to creaking noises. These noises are caused by the casing as it expands or contracts when the temperature changes. If the product is functioning, this may lead to humming noises. These noises are caused by the compressor when the product is in heating mode.
The product releases steam.
In winter and during the thawing procedure, steam may escape from the product. (The heat of the product melts the ice that has formed.)
Other faults Consult your competent
person.
