1.1 INFORMATION PRIOR TO THE INSTALLATION
The electrical installation must comply with the valid national legislation applicable to electrical installations.
AQUA HP will work only after adding the correct dose of coolant.
The maximum recommended pressure of water supplied into the hydraulic circuit is 0.3 MPa, and the minimum pressure is 0.1 MPa.
Power is AC 230 V, 50 Hz and the power cord must be connected to a grounded receptacle. If the power cord is damaged, it must be replaced by the manufacturer or a trained service technician in order to prevent any risk.
AQUA HP shall only be operated if the water heater is filled with water.
Heating other than potable water is not allowed.
1.2 SAFETY INFORMATION
The appliance can be used by children from 8 years of age, persons with physical, sensory or mental disability or people without experience or knowledge, as long as those people were briefed on the operation of this device in a secure manner, and are familiar with the related dangers.
The appliance cannot be played with by children.
Cleaning and maintenance must not be performed by children without proper supervision
- 6 -
During installation:
• The installation of the water heater with heat pump must be performed by a qualified installer
who has been properly trained and qualified to this activity.
• The appliance must not be installed in locations where there is a risk of damage from impact, shock
or explosion.
• Do not unpack the appliance from the package until it is located at the installation site and is ready
for installation.
• Before connecting the appliance to the power, make sure that all hydraulic connections
are watertight.
Maintenance of the appliance:
• Maintenance of the appliance must be performed by a service technician with the exception
of regular and continuous cleaning that should be performed by the user him/herself.
• During maintenance, the appliance equipment must be disconnected from service.
• The manufacturer recommends regular annual inspection of the appliance by a qualified technician.
• Cleaning and maintenance must not be performed by children without proper supervision.
High pressure and temperature:
• The principle of operation of this appliance is associated with high temperature and high pressure.
Contacting the appliance must be done carefully so as to avoid the risk of burns and injuries
by protruding parts.
Coolant
• The coolant used in the cooling circuit is R134a, CFC free, non-flammable and without harmful effects
on the ozone layer.
• However, in accordance with the law, the liquid from the appliance must not be discharged freely
into the environment.
• The liquid in the appliance may only be handled by a qualified technician.
Information for customer
• The installer must inform users about the operation of the appliance, its dangers and responsibilities
of the user.

Expansion valve
Evaporator
Ambient air exhaust
(exhaust duct)
Capacitor
HOT WATER RECEPTACLE
- 9 -
1. The coolant R134a is compressed in a highly efficient compressor that increases its pressure and temperature.
2. In a capacitor that is not in direct contact with water, the thermal energy contained in the coolant is transferred to the water in the hot water storage tank.
3. Condensed liquid flows from the expansion valve that is responsible for a drop in its pressure.
4. The fluid absorbs thermal energy from the air flowing through the evaporator with the help of a fan.
R134a is a HFC coolant, and therefore does not damage the ozone layer. It is characterized by excellent chemical and thermal stability, low toxicity, is not flammable and is compatible with most materials.

TRANSPORT
The appliance must be transported to the installation site in the original packaging and must be transferred in an upright position. When handling the appliance, proceed with maximum caution to avoid the collision that could damage any part of the appliance. Make sure that the transport belts or straps do not cause material damage. For transportation, always use suitable means of transport (pallet truck, forklift, etc.).
The packaging contains the following information symbols:
INSTALLATION
4.1 SAFETY AND CONTROL DEVICE
4.1.1 Low-pressure/high-pressure fuse
In preparation for operation outside the recommended operating pressures defined by the manufacturer, the appliance switches off and the electronic panel displays an error.
4.1.2 Thermal fuse
Thermal fuse is factory set by the manufacturer, and ensures that the water temperature in the hot water tank does not exceed the maximum value. If the temperature exceeds this value, the fuse shuts off backup electric heating. Turning on is performed manually by a service technician after analyzing the reasons for the switching off.
Fragile, handle with extreme caution
Make sure that the arrow always points upwards
Keep the packaging dry
Do not stack the packaging
