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.
► 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.) is present, as this may result in shortened operating life.

suitable for the power requirements
3. Based on the ambient conditions and the setting up criteria for the various model types,
determine the optimum installation location for the indoor and outdoor unit or the compact
device
(→ 5.2 Installation criteria, p.
4. Determine the requirements for the hydraulic connection of the devices
lics, p.
100). Always conform to the valid legal provisions.
5. Determine the requirements for the electrical connection of the devices
p.
105). Always conform to the valid legal provisions.
