Securing the outdoor unit
The outdoor unit must be mounted on a flat, horizontal and solid surface. Take the weight of the
water into consideration, too, besides the weight of the device. You need four M12 anchor bolts,
with a tensile force of more than 15,000 N.
Minimum requirements for anchoring the outdoor unit on the floor over a foundation (A
and B) or directly in the floor plate (C)

5.2.2.4 Installation space requirements for the indoor unit
When planning the installation space, consider all devices and components of the heat pump
system, which are not installed outside the building:
●
Hydro-modules or combination hydro-modules (only for split system).
●
Lines and wall bushings should be arranged functionally and using the shortest
path (electrical cables, coolant and heating water pipelines).
●
Tank (hot water tank as well as possibly buffer tank)
Further, see that the installation space is dry and frost-free and that the installation location is
easily accessible for maintenance work.
Available space of the installation space
In split systems, the coolant is partly in the building, which must be taken into consideration with
respect to the minimum available space. If no special machine space is available according to
EN 378 - Part 1, the minimum required space of the installation space (V
min
) according to EN 378
– Part 1) is calculated for heat pumps as follows:
V
min
=
G
c
Where:
G = Coolant filling quantity in kg
c = practical limit in kg / m³
(for R410A is c = 0.44 kg / m³; for R407C is c = 0.31 kg / m³)
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.
►
For the Aquarea LT and T-CAP series, only use coolant of the type R410A and for the
Aquarea HT series only coolant of the type R407C.
►
Do not mix the prescribed coolant with coolants of another type or replace it with a
coolant of another type.
!
IMPORTANT
The coolant and the coolant filling quantity differ for the individual models and are also
dependent on the additional coolant filling, which goes over the pre-filled connection distance.
