– Operating principle
The operating principle of the equipment (Fig. 1):
I-II: The coolant fluid sucked in by the compressor flows
inside the evaporator and while it evaporates, it
absorbs the “ecological” heat given by the air.
At the same time, the ambient air is sucked into the
equipment by a fan; the air loses its heat by
passing over the finned-tube battery of the
evaporator;
II-III: The coolant gas passes through the compressor
and it undergoes an increase in pressure that
causes the temperature to rise; transforming the
gas into superheated steam;
III-IV: Inside the condenser, the coolant gas releases its
heat to the water inside the tank (boiler). This
exchange process enables the coolant to transform
from superheated steam into a liquid by
condensing at a constant pressure and undergoing
a lowering in temperature;
IV-I: The liquid coolant passes through the lamination
valve, it undergoes a sudden drop in both pressure
and temperature and it partially evaporates
bringing pressure and temperature back to its initial
conditions. The thermodynamic cycle can begin.

Available versions and
configurations
The heat pump is available as a 1.9 kW, which can be
set up in different configurations, depending on the
possible integrations with other heating sources
(e.g. solar thermal, biomass power, etc.).

Handling and transport
The equipment is supplied in a cardboard box. It is
fastened to a pallet with three screws.
Use a fork-lift truck or a pallet truck in order to unload
the equipment: it is opportune for these to have a
load capacity of at least 250 Kg.
In order to loosen the
fixing screws more
easily, you can put
the packaged
equipment on a
horizontal position
on its back side.
The unpacking
operations must be
carried out carefully
to not damage the
equipment
enclosure, if the
unpacking is
carried out with
knives or cutters to
open the cardboard
packaging.
After having removed the packaging, check whether the
unit is intact. If in doubt, do not use the equipment
and seek help from authorised technical staff.
In conformity with the environmental protection
regulations, you should make sure that all
accessories supplied have been removed before
discarding the packaging.
WARNING!
Packaging items (staples, cardboard boxed, etc.)
should not be left within reach of children, as
this can lead to dangerous situations.
(*) Note: at Daikin’s discretion, the type of packaging
may be subject to change.
It is opportune to protect the equipment from
atmospheric agents as long as it remains idle,
waiting to be used.
