INTRODUCTION The aim of this manual is to give information, instructions and warnings on the heat pump water heater. The manual is to be used by installers and plumbers as well as by end users, since it contains important safety indications. The manual is a part of the heat pump water heater and it is to be conserved with care, since it contains important installation and maintenance instructions that can be useful to assure a long life time and an efficient operation. 1. ABOUT THE PRODUCT The product is a heat pump water heater or also domestic hot water heat pump (DHWHP) that has been designed...

1.2. Technical data 1.2.1. General The heat pump water heater is composed of a water tank, a refrigerant circuit, a cabinet and a display connected to a control board. The main scope of the appliance is to heat water stored in a tank. 1.2.2. Operation The unit is programmed to start heating the water inside the tank when its temperature falls below a predetermined level. The unit stops when the water temperature reaches a set point that can be regulated by the user. In general, the appliance is designed to produce enough hot water to cover the need of a household of 4 persons or more. There are...

1.2.3. Cooling circuit As depicted in Figure 1 and 2, the heat pump cycle can be divided in four main processes: compression (1-2), condensation (2-3), expansion (3-4), evaporation (4-1) described below. • At the suction of the compressor (1) the superheated gas refrigerant enters the compressor at low pressure. • In the compressor, the gas is compressed to a higher pressure and temperature level (2). • The gas is first de-superheated and condensed in the condenser, exchanging heat with water stored in the tank. • The refrigerant exits the condenser in a subcooled, liquid form (3) • Through a...

Note: The extensive use of the electric heater leads to higher electricity consumption and it may lead to high electricity bills. The operation with electric heater normally consumes 3 times more electricity than the operation with heat pump. The energy released to the condenser (2-3) is, in fact, the sum between the free energy extracted from the air in the evaporator (1-4) and the energy supplied to the compressor (2-1). On average, the energy absorbed by the evaporator is more than double of the energy used to run the compressor. 1.2.4. Safety instructions – Cooling circuit • Only skilled...

In order to assure an efficient operation, it is suggested to keep the external pressure drops below 200 Pa.

2. TRANSPORT, HANDLING AND DELIVERY Immediately upon receipt, the domestic hot water heater pump must be examined to make sure that it is intact and undamaged. If not, the shipping company must be informed immediately. The recipient has the responsibility for all the shipments unless otherwise agreed. The appliance is delivered without condensate drain tube and the safety equipment for the water circuit. The unit must be stored and preferably transported upright, free of water and within its packaging. Transport and storage may take place at temperatures between -10 °C and +50 °C. If the unit...

2.5. Transport with Trailer The unit must only be transported on the associated transport frame. This also applies to transport on stairs. The unit must be secured against sliding on the trailer. Water connections etc. shall not be used for transportation purposes. It should be made sure that the trailer does not damage the cabinet or the various connections. Figure 8 - Transport with trailer When carefully transporting the unit over a short distance to its final location, the unit can be transported horizontally in its packaging on the dedicated side. If the unit has been tilted more than 45°,...
