ATTENTION
Danger of water pipes freezing in outside temperatures below 0 °C
Once the heating circuit of a mono-bloc system is lled with water and the outside temperature falls
below 0 °C, there is a risk that the water pipes may freeze up. This can cause a lot of damage to
the device.
The client should therefore ensure the absence of frost by taking one of the following measures:
► Operate the heating circuit using a food-safe antifreeze mixture (propylene glycol).
► Provide an additional cabinet heating in the mono-bloc unit, to prevent the heating circuit
from freezing up.
► Drain the water from the heating circuit with eld-supplied equipment (manually or
automatically) before freezing starts.
4.5.2 Series
The Aquarea heat pump system has three di󰀨erent series that are in turn available in multiple
model variants. An overview of the complete range can be found at the beginning of this manual
(→ 1 Model range, p. 8).
With the large number of di󰀨erent model variants, which illustrates the large variety of
characteristics and functions of the Aquarea heat pumps, Panasonic can achieve a high level of
exibility and adaptability for the most varied applications. This is intended to o󰀨er the best possible
solution to address individual heat supply and air-conditioning requirements for buildings using
Aquarea heat pumps.
The following table shows the Aquarea heat pump series and their key characteristics in the context
of typical applications.
