Safety Notices
Danger due to toxic gases if the coolant comes into contact with fire
Toxic gases can be created when escaped coolants come into contact with fire.
For this reason, if coolants escape during installation or operation:
► Extinguish any sources of fire (if present).
► Thoroughly ventilate the room in which the heat pump is installed.
Danger of explosion and injury caused by pressure in the coolant circuit being too high
In the event of improper installation, leaks can occur at the connections of the coolant pipes,
leading to air being sucked in while the compressor is operating. This results in increased pres-
sure in the coolant circuit, leading in turn to increased risk of explosion or injury.
► Carry out installation of the coolant pipes in a proper manner and check that there are
no leaks in the installation before turning on the compressor.
► Before the coolant 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 Notices relating to preventing material
damage
CAUTION
Danger of the devices being damaged by incorrect coolant
The devices must only be operated with the coolants described in this Manual or the respective
operating instructions. The use of other coolants or coolant compounds can lead to the devices
being damaged and to safety risks. Panasonic will not accept any responsibility or liability what-
soever if incorrect coolants are used.
► Only use coolant Type R410A for the Aquarea LT and T-CAP series and only Type
R407C coolant for the Aquarea HT series.
► Do not mix the prescribed coolant with coolants of another type or replace it with a
coolant 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.

Aquarea air-to-water heat pumps - Planning and installation manual - 01/2018
► All relevant European and national provisions (including EN 61770 "Electrical appli-
ances 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 (hydro-modules or combined hydro-modules) are only to be installed in
indoor areas.
● Outdoor units and compact 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 compact 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.
