Version Configuration description
HPWH 3.1 200/260 U02 Air source heat pump for the production of domestic hot water
HPWH 3.1 200/260 U02 S Air source heat pump for the production of domestic hot water suitable for use with the solar
power system or additional heating unit.
I I-III: The coolant gas passes inside the compressor and it undergoes an increase in pressure that causes a rise in temperature;
transforming this into superheated steam;
III-IV: Inside the condenser, the coolant gas releases its heat to the water inside the tank (boiler). This exchange process makes it
possible for the coolant to pass from superheated steam to a liquid state by condensing at a constant pressure and undergoing a
reduction in temperature;
IV-I: The liquid coolant passes through the throttle valve. It undergoes a sudden drop in both pressure and temperature and it par -
tially vaporizes bringing pressure and temperature back to the initial conditions. The thermodynamic cycle can begin.
Position designation on Fig.1
The heat pump is available in two different versions, in relation to the thermal power (with or without additional heat exchanger).
Each version, in turn, can be set up in different configurations, depending on the possible integrations with other heating sources
(e.g. solar thermal, biomass power, etc.).
Not allowed! (Fig.1a) Allowed! (Fig.1b)
While handling, do not catch the unit onto upper decorative panels! There is a risk to damage them!
Equipment is delivered on an individual transport pallet.
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
400 Kg.
The unpacking operations must be carried out carefully so as not to damage the appliance.
For a transport over short distance (provided that it is done with care), an inclination angle up to 30 degrees is permitted
It is advised that the maximum permissible inclination angle of 45 degree is not exceeded. If transport in an inclined position cannot
be avoided, the unit should be taken into operation one hour after it has been moved into final position.
Please follow the described steps bellow in order to mount three supports (fig. 2a):
-Incline the appliance as per Fig. 2a;
-Unscrew the three bolts which hold the pallet to the water heater; Fig.2b
-Mount the adjustable feet directly to the appliance; * Fig.2c
-Put the storage tank in vertical position and adjust the level using the feet.
*If the adjustment feet are delivered in separate parts you can assemble them as follow (fig. 2d):
- put the part 1 on bolt 2 which is unscrewed from the pallet
- put the washer 3 which is removed from the pallet
- Screw on the nuts 4 which are delivered with the appliances
The water heater must (in compliance with Article 20 of Standard EN 60335-1) be fixed to the
ground using the fixing bracket provided for this purpose according to Fig 2e.
After having removed the packaging, make sure that the unit is intact. If in doubt, do not use the equipment and seek help from
authorized technical staff.
In conformity with environmental protection regulations, make sure that all the accessories supplied have been removed
before discarding the packaging.
