4. Technical Description
4.1 General
This facility is a thermal pump which is designed for generating hot water in residential properties and other
premises in which the daily hot water requirement does not exceed 00 litres. With the heating of domestic
water, the heat pump simultaneously cools down the area in which it is installed. The intended use of the
heat pump, in addition to saving large amounts of energy when generating hot water, is to cool down a
selected room (e.g. cellar, storage room etc.). Any change to or replacement of the original components, and
any improper or incorrect use of the device, will nullify the manufacturer's liability, guarantee and warranty.
Consequential costs of any damage which is caused must be paid by the user.

4.2 Structure
Heating water with a heat pump is an environmentally friendly and efficient method of supply water in
buildings. The WPA
303 ECO is a unit comprising a water heater and assembly (compressor, evaporator,
fan, etc.). The hood of the heat pump is made of plastic and has two pipe nozzles for connection to a pipe
system. The heat pump also offers the possibility of ventilating a
compressor, evaporator, centrifugal ventilator, dry filter, copper and electric installation. The heat pump
assembly operates the entire thermodynamic process for the water heater in the storage tank.

El. heating rod
The refrigerant circuit in the thermal pump is a closed system in which the cooling agent R134a is circulated
as the energy carrier. When the evaporating temperature is low, heat is extracted from the suctioned air in
the fin coil heat exchanger and transferred to the cooling agent. The vaporous cooling agent is suctioned
from the compressor, compressed to a higher pressure and temperature level and further transported to the
condenser. Here, the heat absorbed in the evaporator and a part of the compressor energy is released into
the water. Using a throttle (expansion valve), the evaporation pressure is reduced and the cooling agent can
continue to absorb heat from the suctioned air.
Water heater (hot water tank)
The water heater is enamelled on the inside, cased on the outside with polyurethane and surrounded with
steel plate. The water heater contains a heat exchanger as standard for connection with the boiler; this is
used when bivalent operation is selected. A protective anode is fitted in the water heater which prevents
corrosion in the event of damage to the enamel. In order that the device can be set up on an uneven surface,
three knuckle feet are enclosed loose which are covered with heat insulation during the foaming process.
Remove this heat insulation before screwing the feet on. Please use a water level to ensure a horizontal
alignment.
dditional electric heating rod
The electric heating rod EH installed with output of 1.5 kW is used for:
• fast water heating; the WP and the heating rod are active simultaneously
• The protection function of the evaporator; heater turns on automatically when the HP is running
during summer operation and the ambient air temperature drops too far
• alternative heating; in the case of failure of the assembly.

Frost protection sensor
The thermal pump regulator has an air temperature sensor which measures the temperature of the air which
flows through the evaporator and switches off the TP at an air
In this case, heating is automatically reconnected using an electro heating rod when the HP is in
summertime operation. In wintertime operation, the circulation pump of the connected boiler is switched on.
Safety thermostat of the el
ectric heating rod
The safety thermostat switches off at 85 °C and must then be reset manually.
Monitoring the hot water temperature in the storage tank
The OPTITRONIC regulator is used to monitor the hot water temperature. Depending on the hot water
temperature, this regulator
switches the compressor, the ventilator and, in certain cases, the electric heating
rod or the circulator pump of the boiler on and off. The maximum temperature which can be set is 55°C when
operating with the compressor. In the case of rapid heating using
High pressure control
A high pressure control is fitted in order to protect against excessive pressure in the refrigerant circuit; in the
event of an increase in pressure, the heat pump switches off and thus prev
If the pressure in the system drops, the heat pump is automatically switched on again. In this case "E "
appears on the display.

5.5 Installation
5.5.1 Hydraulic connections
The water pipe must be connected in accordance with the
connection of water heaters. How to connect the water pipe is shown in Figure 3. The maximum pressure in
the water pipe must not be more than 6 bar. The smooth pipe heat exchanger must be professionally flushed
thro
ugh before carrying out the initial installation (in addition we recommend the installation of a dirt filter). If
the smooth pipe heat exchanger is not used during the operation of the storage tank (e.g. HP only) then this
must be completely filled with a
glycol mixture to avoid corrosion due to the resulting condensation. After it
has been filled up, the filled smooth pipe heat exchanger must not be closed off at both ends (pressure
expansion due to temperature).

5.5.2 Air duct connection
The heat pump with air duct has several advantages over the standard compact version and also over the
design with a separate evaporator:
• The heat pump can be set up in any room which is big enough to accommodate it.
• The thermal pump enables the ventilation of a selected room
• The heat pump enables the drawing off of the ambient air and also enables the supply of fresh air
from the surroundings.
• When selecting the room, take into account the diameter and height of the heat pump. There must
be sufficient space above for the pipe channel connections. The minimum distance to the walls must
be 0.5 m.
The air piping system should be designed in such a way that, on its way, the air does not change the
direction of its flow if possible. The pipe length between the intake connection and the outlet connection
should not exceed 10 m. If the flow direction changes more often, that must be regarded as additional air
resistance and the pipe length should be shortened accordingly. A 90° bend therefore means a pipe channel
shorter by 0.5 m. Closure elements (gates, filters, ventilation valves) in the air ventilation system must be
taken into account in the same way. A drop in pressure in the pipe channel which is too high reduces the air
flow. If the air temperature is below +10°C, this can cause the slow freezing of the evaporator and thus
poorer ventilation, which is something which is difficult to notice.
REM RK
It is necessary to install at least a 90° elbow pipe in order to avoid a mixture of air
between the suctioning air channel and the blowing out air channel.
