INSTALLATION OF THE HEAT PUMP

The heat pump can be used using the ambient air or air from other premises. The heat pump must be installed in a frost-free room. When selecting a place for installation, particular attention should be paid that the selected air intake location is dust free, because dust has adverse effects on the heat pump performance. When selecting the place of installation, pay attention to the solidity of the wall – can it take the weight of the heat pump together with the weight of the water inside the boiler? Take all the necessary precautions to prevent the operation noise and vibrations from transferring through the walls to the premises where this would be disturbing (bedrooms, rest areas). Do not install the heat pump and its air intake in premises with other air consumption appliances (gas boilers, solid-fuel fireplaces, dust extraction appliances etc.) During installation, please bear in mind the minimum distances from the wall, ground and ceiling. The condensate outlet from the heat pump is placed on the bottom left side in the form of a plastic tube with an external diameter of 18 mm. This tube should be connected to the external condensate outlet pipe and led to the sewage system or a container. The quantity of condensate depends on air temperature and humidity when the heat pump is in operation.

To prevent pressure depression in the building, fresh air must be regularly supplied to the premises. The desired rate of air exchange for a residential building is 0.5. This means that the entire quantity of air in the building is exchanged every two hours.

Connecting the heat pump to the same pipeline as the kitchen extractor fan or taking air out of several smaller apartments or suites is not allowed.

Fig. 3: Ventilation

To minimize the transfer of noise and vibrations through walls into the premises where this would be disturbing (bedrooms, rest areas), please take the following measures:

• install flexible joints for hydraulic connections
• install a flexible tube for the pipeline of inlet/outlet air
• plan vibration insulation for wall openings
• plan noise dampers for inlet/outlet air
• pipelines for inlet/outlet air should be attached using noise dampers
• plan vibration insulation against the wall

a) Operation using ambient air

In this type of operation, the device heats domestic water using only the amount of energy generated by the air from the room where the device is installed. The heat pump must be installed in a ventilated, frost-free room, possibly in the vicinity of other heating sources. For optimal performance of the heat pump, we recommend a sufficiently large and well ventilated room with the temperature ranging between 15 °C and 25 °C. It is vital to ensure sufficient intake of air in the room. Elbows must be installed on the heat pump and turned so that they prevent the mixing of air. Heat losses are greater in premises with colder air.

If the heat pump is installed in a frost-free room and the temperature is under 7 °C , the heat pump operates in the normal mode of operation.

b) Operation using air from other premises

In this type of operation, the heat pump uses air from other premises via a pipeline system. It is advisable to insulate the pipeline system to prevent the formation of condensate. In case of using air from outside, the external part must be covered so as to prevent the intrusion of dust or snow into the appliance.

Besides the drag in the pipes and elbows, the user should be aware that increased drag also increases noise levels.

In case of using air from outside, the user should adhere to the minimum diameter of the pipes 125 mm or 150×70 .

To make sure the operation of the pump is effective at all times, you can install dampers to take air from the premises and then return it either to the premises or outside. If the temperature of air is under -7 °C, heaters for the heating of domestic water are switched on. The heat pump operates in reserve mode.

PRESSURE LOSS IN CASE OF USING THE PIPELINE SYSTEM

In planning the pipeline system for the inlet and outlet of air to and from the heat pump, the key element is to take into account the aerodynamic character of the fan which also causes the loss of static pressure.

Presentation of the diagram of aerodynamic characteristics for different speeds of the fan

The diagram (Diagram 1) includes aerodynamic characteristics of the operation of the fan. The top (purple) line represents the curve of air flow depending on the pressure drop at maximum speed of the fan (100 %). The bottom (brown) line represents the operation of the fan at minimum speed (40 %). The curves between (60 %, 80 %) represent the aerodynamic characteristics at lowered revolutions of the fan. The bottom (red) line that lies between points (0,0) and (340,50) represents the internal drop of static pressure created by the evaporator alone, without overloading the pipeline system. This pressure drop cannot be eliminated.

- Area of more efficient use – volumetric flow of air is higher here, which requires a lower pressure drop (channel system with minimum pressure drop). Fan is set to higher speeds.

- Operating area with a normal air flow with respect to the pressure drop and fan setting.

Diagram 1: Aerodynamic characteristics

Air inlet and outlet pipeline system

When connecting the sanitary heat pump to an existing pipeline system, we use the basic pipe elements that we connect into a pipeline system for air inlet and outlet. The air pipeline should consist of round pipes with an inner diameter of 125 mm, or rectangular pipes with a cross section of 150×70 mm.

Fig. 6: Schematic demonstration of the basic elements in a pipeline system for inlet and outlet of air

Calculation of pressure drops

The values of total static pressure drop can be calculated by adding up the losses from individual elements built into the air pipeline system and the internal static pressure. The values of static pressure drops of individual elements (static pressure drops of elements relate to the internal diameter 125mm or 150x70mm ) are shown in Table no. 2.

Type of element	Value of static pressure loss
a.) Spiral ribbed pipe	Diagram 2
b.) Rectangular pipe □150x70 mm	Diagram 2 (according to DN 125)
c.) Rectangular elbow - horizontal 90°	5 Pa
d.) Elbow 90° 4 Pa
e.) Angular reducer ø125 to □150x70 5 Pa
f.) Rectangular elbow - vertical 90° 5 Pa
g.) Elbow 45° 3 Pa
h.) Reducer ø125 to □150x70 3 Pa
i.) Flexible tube	Diagram 2
j.) Air intake grid 25 Pa

	Number of elements	p (Pa)	p (Pa)
Rectangular elbow horizontal 90°	4	5	20
Flexible tube (DN125)	13.5	1.85(at 150 m3/h)	25
Air intake grid	1	25	25
Total:	70

Table 3: Example of pressure drop calculation

Note:

As mentioned above, the total loss of static pressure, which can be calculated by adding up the losses of individual elements built into the pipeline system, may not exceed 95 Pa. If they do, the values of COP start dropping more dramatically.

DETERMINING THE FAN SETTING

When pressure drop is determined, select the mode in which the fan will operate. This determines the speed of the fan. The mode is selected using Diagram no. 1, which shows the aerodynamic characteristics of the fan depending on the air flow and pressure drop in the pipeline*.

Note:

*Pressure drop in the pipeline – in diagram 1 this is marked as pressure difference.

Zone of operation of the sanitary heat pump

On diagram 1 there are two zones of operation of the sanitary heat pump among the curves:

• The dark green zone represents the area of use with higher efficiency. The volumetric air flow is higher in this zone, which requires a lower pressure drop (channel system version with minimum pressure drop).
• The light green zone represents the area of use with lower air flow in relation to the pressure drop and fan setting.

Noise

Like the aerodynamic characteristics rise from the lowest to the highest, the noise increases as well. Between the aerodynamic characteristics 80% and 100% there is a zone with increased noise.

Checking the calculation of pressure drop

Determining the aerodynamic characteristics based on the calculation of pressure drop while taking into account individual elements of the pipeline and air flow is an iteration. Once the aerodynamic characteristic has been determined and set, we must measure the air flow in the pipeline. If the air flow does not correspond to the ventilation system, we select the next higher or lower aerodynamic characteristic that corresponds to the ventilation system.

Selecting the operating point of the fan for the ventilation system

When determining the speed of the fan, we must know the maximum air flow for ventilation and pressure drop caused by the pipeline. In Diagram 1, find the desired air flow and draw a vertical line, then draw a horizontal line at the pressure drop that you have calculated (based on the existing pipeline). Select the fan characteristic curve that lies the closest to the point where the lines cross.

Example of selecting the aerodynamic characteristic

In diagram 3 at air flow of 150 m^3/h draw a vertical line. The pipeline represents 70 Pa of pressure drop, which is added to the below (red) line**. Total pressure drop is thus 90 Pa. Draw a horizontal line at the pressure drop of 90 Pa. The point where the lines meet lies on the curve that corresponds to 60% speed of the fan. This is the standard setting of the fan that has also been preset by the manufacturer.

Note:

**Line, represents the internal static pressure drop created by the evaporator.

Diagram 3: Example of determining aerodynamic characteristic

CONNECTION TO WATER SUPPLY MAINS

Water inlet and outlet on the heat pump are marked with colours. Cold water inlet is marked with blue, and warm water outlet is marked with red. The heat pump is designed for connection to indoor water supply mains without using the relief valve if the pressure in the supply mains is lower than 0.6 MPa (6 bar). If the pressure is higher, a relief valve needs to be installed so as to provide that the pressure at the inlet to the hot water tank does not exceed the nominal pressure.

Installing a safety valve is mandatory in order to assure safe operation. The valve prevents an increase of the pressure in the boiler by any more than 0.1 MPa (1 bar) above the rated pressure. The outflow nozzle on the safety valve must have an outlet into the atmosphere. To assure correct operation of the safety valve, the valve must be regularly checked.

When checking the valve, push the lever or unscrew the nut of the valve (depending on the type of the valve) and open the drain from the safety valve. Water must flow from the valve nozzle, showing that the valve operation is faultless. During the heating of water, the water pressure in the hot water tank is increased up to the level preset in the safety valve. Since the system prevents backflow of water into the water supply mains, water may be dripping from the outlet opening on the safety valve. The dripping water may be drained via trap into the drains; the trap is mounted under the safety valve. The outlet pipe, which is mounted under the safety valve, must be directed downwards, in a place with a temperature above freezing.

If the installation does not allow draining of the water from the safety valve into the drains, dripping can be avoided by installing an expansion vessel onto the heat pump inlet pipe. The volume of the expansion vessel must be ca. 3% of the hot water tank volume.

Starting/stopping the heat pump

• To start the heat pump hold field no. 9.
When the appliance is switched on, the fan starts first and operates for one minute (symbol no. 20 is displayed). If the temperature of inlet air is appropriate, the controlling unit switches on the compressor and the heat pump operates in normal

mode (symbols 16 and 20 are displayed). The heat pump is on, the screen remains unlit and inactive.

In 60 seconds after the last touch of the screen, the illumination and activity of the screen are turned off, but that does not affect the operation of the heat pump.

Pressing anywhere on the screen re-activates the screen and its illumination.

If trying to start up at a lower temperature, please see chapter "Operation at lower temperatures".

- By holding field no. 9, the heat pump is switched off. The appliance stops functioning and the only field visible on the screen is field no. 9. (If you switch off the heat pump for a longer period of time, the water must be drained from the pump if there is any danger of freezing).

Power failure protection

In case of power failure, the settings remain stored for up to 23 hours.

After restarting, the heat pump operates in the same mode it was operating in before the power failure.

Operation at lower temperatures

When the appliance is switched on, the fan starts first and operates for one minute (symbol no. 20 is displayed). If the temperature of inlet air is lower than -7 °C, the fan is turned off. Domestic water is heated with heaters. The heat pump operates in the reserve mode (symbol no. 14 is displayed). The possibility of switching to normal mode is checked every 2 hours by switching on the fan for one minute. If the temperature of inlet air is higher than -7 °C, the heat pump switches to normal mode of operation (symbols 16 and 20 are displayed). The heaters switch off. The heat pump is on, the screen remains unlit and inactive.

At lower air temperatures, the evaporator defrosting cycle is started if necessary.

Symbol no. 19 is displayed on the screen. The fields 2, 4, 6, 11, 13 and 15 remain inactive. Defrosting takes place until the conditions for normal operation of the heat pump are achieved.

After successful defrosting, the heat pump returns to normal operation (symbols 16 and 20 are displayed).

If defrosting is unsuccessful after two consecutive attempts, the controlling unit displays an error message. Field no. 4 starts flashing, accompanied by warning beeps. By pressing field no. 4 the warning beeps can be turned off. Error code E247 appears in field no. 12 and the pump switches automatically to heating with electric heaters. The screen displays symbol no. 14. The error code can be deleted at any time by pressing field no. 4. Field no. 12 resumes to displaying time.

Setting the clock and day of the week

No – heat pump version TC Z, heat pump operation mode 7°C, the system does not include a 4-way valve

Note:

****The low-temperature mode of operation of the heat pump is a setting that the installer can only set if the version of the heat pump is appropriate. When replacing the electronic module, the mode of operation must be selected in such a way that it suits the version of the heat pump!

SERVICE AND MAINTENANCE

If installed and used correctly, the heat pump will last for years without service.

The exterior of the heat pump should be cleaned with a mild detergent solution. Do not use solvents or abrasive cleaning agents.

If the heat pump was exposed to dust, evaporator lamellas might become blocked, which can have a detrimental effect on the functioning of the heat pump. In this case the evaporator should be cleaned. The cleaning of the evaporator must be carried out by an authorised service provider.

By performing regular service inspections you can ensure faultless operation and a long life span of the heat pump. The tank corrosion warranty applies only if the prescribed regular anode inspections have been performed. The interval between individual inspections should not be longer than 36 months. Inspections must be carried out by an authorised service provider that logs each inspection on the product's warranty sheet. The service provider inspects the wear and tear of the anti-corrosion protective anode and cleans the limescale that accumulates inside the tank, depending on the quality, quantity and temperature of the water used. Service providers will also provide you with the following inspection date, depending on the state of the heat pump.

Before calling your service provider, check the following:

• Is everything OK with the power supply network?
• Is the air outlet obstructed?
• Is ambient temperature too low?
• Can you hear the operation of the compressor and fan?
• Pipeline system pressure drop

Do not try to eliminate malfunctions by yourself, call your nearest authorized service provider!

DEFINIRANJE PADA TLAKA U CJEVOVODNOME SUSTAVU DOVODA I ODVODA ZRAKA

-Područje uporabe s većom učinkovitošću – zapremninski protok zraka u toj je coni viši, što iziskuje niži pad tlaka (inačica sustava kanala s minimalnim padom tlaka). Ventilator je podešen na više brzine.

- Radno područje s normalnim protokom zraka s obzirom na pad tlaka i podešavanje ventilatora.
