General Safety Notes Relating To Preventing Material Damage; General Further Information - Panasonic Aquarea WH-ADC0309J3E5 Planning And Installation Manual

Danger of explosion and injury caused by pressure in the refrigeration circuit being too high
In the event of improper installation, leaks can occur at the connections of the refrigerant pipes,
leading to air being sucked in while the compressor is operating. This results in increased pressure
in the refrigeration circuit, leading in turn to increased risk of explosion or injury.
► Carry out installation of the refrigerant pipes in a proper manner and check that there are
no leaks in the installation before turning on the compressor.
► Before the refrigerant pipes are removed or work is carried out on the pipes, switch the
compressor off.
Danger of illnesses caused by colonies of bacteria in the water
The risk of colonies of bacteria, particularly of Legionella, in the water can be raised with an open
water circuit.
► Only deploy devices in a closed water system.
3.2 General Safety Notes relating to preventing material
damage
ATTENTION
Danger of the devices being damaged by incorrect refrigerant
The devices must only be operated with the refrigerants described in this Manual or the respective
operating instructions. The use of other refrigerants or multi-component refrigerants can lead to the
devices being damaged and to safety risks. Panasonic will not accept any responsibility or liability
whatsoever if incorrect refrigerants are used.
► Only use R32 refrigerant for Aquarea High Performance and T-CAP series models of the
J Generation, only use R410A refrigerant for the Aquarea High Performance and T-CAP
series models of the H Generation and only use R407C refrigerant for the Aquarea HT
series models of the F and G Generation.
► Do not mix the prescribed refrigerant with refrigerants of another type or replace it with a
refrigerant of another type.
Danger of other material damage to the devices, e.g. due to vibrations, water leaks or fire
► Any work on the water circuit must be carried out by a trained technician.
► All relevant European and national provisions (including EN 61770 "Electrical appliances
connected to the water mains") are to be observed in installation work for the water
circuit.
► Adhere to the conditions prescribed for the installation site:
● Indoor units (hydrokits or All in One units) are only to be installed in indoor areas.
● Outdoor units and mono-bloc devices are only to be installed in outdoor areas.
► Adhere to the prescribed sequence of installation steps.
► Only use parts and tools delivered with the equipment or as specified.
► As far as possible, avoid installation of outdoor units and mono-bloc devices near the
sea, in regions with a high content of sulphur or at sites where large quantities of oil (e.g.
machine oil, etc.) are present, as this may result in shortened operating life.
