Imminent danger to life or risk of severe personal injury Danger! Risk of death from electric shock Warning. Risk of minor personal injury Caution. Risk of material or environmental damage 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 There is a risk of injury or death to the user or others, or of dam1.2 General safety age to the product and other information property in the event of im1.2.1 Danger caused by proper use or use for which it improper operation is not intended.

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 1.2.6 Risk of being scalded by point is touched. hot drinking water ▶ If coolant escapes, do not touch any components of the There is a risk of scalding at product. the hot water draw-off points ▶ Do not inhale any steam or if the hot water temperatures gases that escape from the are greater than 50 °C.

Changes must not be made to the following equipment: – The heat pump – The heat pump environment – The drain line and expansion relief valve for the heating water – The water and electricity supply lines – The heat pump's condensate drain pipework – The structural conditions that may affect the operational safety of the product. 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 maintenance 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 maintenance 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 1.2.10 Risk of injury and during freezing conditions and material damage due to that all rooms are sufficiently incorrect maintenance heated. or repairs Even if rooms, or the whole As a result of unauthorised indwelling, are not in use for certerference or tampering with the tain periods, the heating must product or parts of the system, remain in operation. 0020151761_04 aroTHERM Operating instructions 5 1 Safety 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 6 during a power cut, note the following: ▶ Contact your competent person for advice on installing an emergency power generator. ▶ Ensure that the technical values 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: – 1 phase: 230 V (+10/-15%) ~50 Hz – 3 phases: 400 V (+10/-15%) 3 N ~50 Hz Operating instructions aroTHERM 0020151761_04 Safety 1 1.2.16 Avoid environmental damage caused by escaping coolant The product contains R410A coolant. The coolant must not be allowed to escape into the atmosphere. R410A is a fluorinated greenhouse gas covered by the Kyoto Protocol, with a GWP of 1725 (GWP = Global Warming Potential). If this gas escapes into the atmosphere, its impact is 1725 times greater than the natural greenhouse gas CO2. Before the product is disposed of, the coolant that is contained in it must be completely drained into a suitable vessel so that it can then be recycled or disposed of in accordance with regulations. ▶ Ensure that only officially certified competent persons with appropriate protective equipment carry out maintenance work on the coolant circuit or access it. ▶ Arrange for the coolant contained in the product to be recycled or disposed of by certified competent persons in accordance with regulations. 1.3 Intended use 1.3.1 State-of-the-art technology The Vaillant aroTHERM heat pump systems are constructed using state-of-the-art technology in accordance with the recognised safety rules and regulations.

Switch the product off before you clean it. 2. Clean the product's casing with a damp cloth and a little soap. Never use scouring or cleaning agents which could damage the casing or the operator control elements. 0020151761_04 aroTHERM Operating instructions 15 6 Troubleshooting 3. Do not clean the product with a highpressure cleaner. 4. At regular intervals, check that no branches or leaves have gathered around the product. 2. The maintenance intervals depend on the local conditions and the use of the product. 3. Have parts that are relevant to the function and safety replaced by a competent person. 5.6.2 Checking the maintenance plan 5.7 Danger! Risk of injury and risk of material damage due to neglected or incorrect maintenance and repairs. Neglected or incorrect maintenance work or repairs may lead to personal injury or damage to the product. ▶ ▶ If, during long periods of absence, the power supply to the dwelling and to the product is interrupted, have the heating system drained by your competent person or have it sufficiently protected against frost. 6 Troubleshooting Never attempt to carry out 6.1 maintenance work or repairs on the product. Employ an authorised heating specialist company to complete such work. We recommend making a maintenance agreement. Reading the fault message Fault 01/3 42 Coding resistor Back Delete Fault messages have priority over all other displays and are shown instead of the basic display. If several faults occur at the same time, these are each displayed alternately for two seconds each. 1. Regular inspection/maintenance of your product by a competent person is a prerequisite for ensuring that the system is constantly ready and safe for operation, reliable and has a long service life. ▶ Note Failure to carry out maintenance and repair work, and noncompliance with the specified inspection, maintenance and replacement intervals, leads to a loss of potential guarantee claims. We recommend making a maintenance agreement with a competent person. 16 ▶ Having the product temporarily decommissioned ▶ If your product displays a fault message, contact a competent person.

Remedy (→ Page 17) ▶ If the product still does not function after the fault has been rectified, contact your competent person. Fault Cause The product no longer works. The power supply has been disconnected Remedy 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, If the heating demand stops, this may lead to bubbling and whistling humming) 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.
