1.4 Energy-efficient use of the heat

pump By operating this heat pump you are helping to protect our en-vironment. Both the heating system and the heat source mustbe properly designed and dimensioned to ensure efficient op-eration. It is particularly important to keep water flow tempera-tures as low as possible. All connected heat consumers shouldtherefore be suitable for low flow temperatures. Raising theheating water temperature by 1 K corresponds to an increase inelectricity consumption of approx. 2.5 %. Low-temperatureheating systems with flow temperatures between 30 °C and50 °C are particularly well-suited for energy-efficient operation. 2 Intended use of the heat pump

2.1 Intended purpose

The water-to-water heat pump is to be used exclusively for theheating of heating water. It can be used in newly built or previ-ously existing heating systems. Water is used as the heat car-rier. It can be supplied by wells or other water systems.In order to eliminate the risk of corrosion at the evaporator, thewell water must be evaluated regarding the corrosion behaviourof metallic materials according to DIN 50930.Details can be found in the project planning and installationmanual for heat pumps for heating purposes. CAUTION!

The well water must comply with the required water qualitystandards.(Cap. 9.4 on page 9)

2.2 Operating principle

A well pump conveys the water to the evaporator of the heatpump. There the heat is transferred to the refrigerant in the re-frigerating circuit.The refrigerant is drawn in by the electrically driven compres-sor, compressed and "pumped" to a higher temperature level.The electrical power needed to run the compressor is not lost inthis process. Most of it is absorbed by the refrigerant.The refrigerant subsequently passes through the liquifier whereit transfers its thermal energy to the heating water. Dependingon the set operating point, the heating water can thus beheated up to a max. of 62 °C.www.glendimplex.de 452237.66.49a · FD 0108 EN-3 WI 35TU - WI 45TU English 3Basic device The device consists of a heat pump for indoor installation wiredready for use with metal casing, switch box and integrated heatpump manager. The refrigeration circuit is "hermetically sealed"and contains the fluorinated refrigerant R410A included in theKyoto protocol. Information on the GWP value and CO equiva- lent of the refrigerant can be found in the chapter Device infor- mation. The refrigerant is CFC-free, non-ozone depleting andnon-combustible.All components required for the operation of the heat pump arelocated in the switch box. An outside temperature sensor in-cluding fixing accessories and a dirt trap are supplied with theheat pump. The supply for the supply voltage and the controlvoltage must be installed by the customer.The circulating pumps included in the scope of supply must beinstalled in accordance with the hydraulic diagrams (see Cap. 4on page XX) or the development documents. The electricalconnection of the circulating pumps must be established in ac-cordance with Cap. 7.5.3 on page 8. The control wire of the primary pump (to be provided by the customer) is to be connected to the control box. When so do-ing, a motor protecting device is to be installed, if required.The customer must provide hydraulic components for the wellwater circuit.1) Switch box2) Evaporator3) Liquefier4) Filter dryer5) Compressor 16) Compressor 27) Expansion valve8) Economiser 4 Accessories

A remote display adds convenience and is available as a specialaccessory. Operation and menu navigation are identical tothose of the heat pump manager. Connection takes place via aninterface (special accessories) with RJ 12 Western plug. NOTE

In the case of heating controllers with a removable controlpanel, this can also be used directly as a remote display.

4.2 Building management system

The heat pump manager can be connected to a building man-agement system network via supplementation of the relevantinterface plug-in card. The supplementary installation instruc-tions of the interface card must be consulted regarding theexact connection and parameterisation of the interface. The following network connections can be made on the heatpump manager: Modbus EIB, KNX Ethernet CAUTION!

If the heat pump or circulating pumps are controlledexternally, a flow rate switch is required to prevent thecompressor from being switched on when there is no volumeflow. 5 Transport A lift truck is suited for transporting the unit on a level surface.Carrying straps may be used if the heat pump needs to betrans-ported on an uneven surface or carried up or down stairs.These straps can be passed directly underneath the pallet. CAUTION!

The heat pump must not be tilted more than 45° (in anydirection).

.EN-4 452237.66.49a · FD 0108 www.glendimplex.de English WI 35TU - WI 45TU Use the holes provided in the sides of the frame to lift the unitwithout the pallet. The side panel assemblies must be removedfor this purpose. Any commercially available length of pipe canbe used as a carrying aid. After transportation, the transport fastening in the device is to be removed from both sides of the base. CAUTION!

Before commissioning, the transport fastening must beremoved.All panelling can be removed to allow accessing the inside ofthe device.Loosen the screws for this purpose. The panels can be removedtoward the top when slightly tilted. 6 Installation

6.1 General Information

The brine-to-water heat pump must be installed in a frost-free,dry room on an even, smooth and horizontal surface. The entirebase of the frame should lie directly on the floor to ensure anadequate soundproof seal. If this is not the case, additionalsound insulation measures may be necessary.The heat pump must be installed so that maintenance work canbe carried out without hindrance. This can be ensured by main-taining a clearance of approx. 1 m in front of the heat pump.Neither frost nor temperatures higher than 35? must occur inthe installation location at any time of the year. NOTE

The heat pump is not intended for use over 2000 metresabove sea level.

6.2 Acoustic Emissions

The heat pump operates silently due to efficient sound insula- tion. Internal insulation measures should be carried out to pre- vent vibrations from being transmitted to the foundation or tothe heating system. 7 Installation

The following connections need to be established on the heatpump. The hydraulic integration diagram must be adhered to: Flow and return of the well system Flow and return of the heating system Temperature sensor Voltage supply

7.2 Connection on the heating side

Flush the heating system prior to connecting the heat pump. Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down. Once the heat pump has been connected to the heating sys- tem, it must be filled, de-aerated and pressure-tested. CAUTION!

The maximum test pressure in the heating circuit and the primary circuit is 6.0 bar. This value must not be exceeded. The following points must be observed when filling the system: Untreated filling water and make-up water must be of drinking water quality. (colourless, clear, free of sediments) Filling water and make-up water must be pre-filtered (max. pore size 5 µm). Scale formation in domestic hot water heating systems cannot be avoided, but in systems with flow temperatures below 60 °C, the problem can be disregarded. With high-temperature heat pumps and in particular with bivalent systems in the higher per- formance range (heat pump + boiler combination), flow tem- peratures of 60 °C and more can be achieved. The following standard values should therefore be adhered to with regard to the filling and make-up water according to VDI 2035, sheet 1: The total hardness values can be found in the table. Fig. 7.1:Guideline values for filling and make-up water in accordance withVDI 2035 For systems with an above-average specific system volume of 50 l/kW, VDI 2035 recommends using fully demineralized water and a pH stabiliser to minimize the risk of corrosion in the heat pump and the heating system. CAUTION!

With fully demineralized water, it is important to ensure that the minimum permissible pH value of 7.5 (minimum permissible value for copper) is complied with. Failure to comply with this value can result in the heat pump being destroyed. Minimum heating water flow rate The minimum heating water flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing a dual dif- ferential pressureless manifold. The frost protection function of the heat pump manager is ac- tive whenever the heat pump manager and the heat circulating pumps are ready for operation. The system must be drained if the heat pump is taken out of service or in the event of a power failure. If heat pump systems are implemented in buildings where a power failure cannot be detected (holiday homes etc.), the heating circuit should be operated with suitable frost pro- tection.

7.3 Heat source connection

The following procedure must be observed when making the connection: Connect the well pipes to the heat pump's flow and return. CAUTION!

It is essential that the dirt trap included in the accessories pack is installed in the return (inlet). CAUTION!

The well water must comply with the required water quality standards (see Cap. 9.4 on page 9). CAUTION!

The flow rate switch available as an accessory must be installed in the flow (outlet) of the heat source. The hydraulic integration diagram must be adhered to.

The following temperature sensors are already installed or must be installed additionally: Outside temperature sensor (R1) supplied (NTC-2) Return temperature secondary circuit (R2) installed (NTC-10) Return temperature primary circuit (R24) installed (NTC- 10) Flow temperature secondary circuit (R9) installed (NTC-10) Flow temperature primary circuit (R6) installed (NTC-10)

7.4.1 Sensor characteristic curves

The temperature sensors to be connected to the heat pump manager must correspond to the sensor characteristic curve il- lustrated in Fig. 7.2 on page 6. The only exception is the outside temperature sensor included in the scope of supply of the heat pump (see Fig. 7.3 on page 6) Fig. 7.2:Sensor characteristic curve NTC-10 Fig. 7.3:Sensor characteristic curve NTC-2 according to DIN 44574 Out- side temperature sensor

7.4.2 Mounting the outside temperature

sensor The temperature sensor must be mounted in such a way that all weather conditions are taken into consideration and the meas- ured value is not falsified. On the external wall of a heated room used as living space, if possible on the north or north-west side of the building Do not install in a “sheltered position" (e.g. in a wall niche or under a balcony) Not in the vicinity of windows, doors, exhaust air vents, ex- ternal lighting or heat pumps Not to be exposed to direct sunlight at any time of year

It is only necessary to mount the strap-on sensors if they are in- cluded in the scope of supply of the heat pump but have not yet been installed. The strap-on sensors can be fitted as pipe-mounted sensors or installed in the immersion sleeve of the compact manifold. Mounting as a pipe-mounted sensor Remove paint, rust and scale from heating pipe. Coat the cleaned surface with heat transfer compound (ap- ply sparingly). Attach the sensor with a hose clip (tighten firmly, as loose sensors can cause malfunctions) and thermally insulate.

7.4.4 Hydraulic distribution system

The compact manifold and the dual differential pressurelessmanifold function as an interface between the heat pump, theheating distribution system, the buffer tank and, in some cases,even the domestic hot water cylinder. A compact system isused to simplify the installation process, so that a lot of differentcomponents do not have to be installed individually. Further in-formation can be found in the relevant installation instructions. Compact manifold The return sensor can remain in the heat pump, or should be in-stalled in the immersion sleeve. The remaining empty space be-tween the sensor and the immersion sleeve must be filled com-pletely with heat transfer compound. Dual differential pressureless manifold In order for the heating circuit pumps of the generator and con-sumer circuits to supply the flow to the return sensor, this mustbe installed in the immersion sleeve of the dual differentialpressureless manifold.

7.5 Electrical connection

All electrical installation work must be carried out by a trainedelectrician or a specialist for the specified tasks in accordancewith the installation and operating instructions, country-specific installation regulations (e.g. VDE 0100), technical connection conditions of the energy suppliers and supply grid operators (e.g. TAB) and local conditions. To ensure that the frost protection function of the heat pumpworks properly, the heat pump manager must remain con-nected to the power supply and the flow must be maintainedthrough the heat pump at all times.The switching contacts of the output relay are interference-suppressed. Therefore, depending on the internal resistance ofthe measuring instrument, a voltage can also be measuredwhen the contacts are open. However, this will be much lowerthan the line voltage.Extra-low voltage is connected to controller terminals N1-J1 toN1-J11; N1-J19 to N1-J20; N1-J23 to N1-J26 and the terminalstrips X3. If, due to a wiring error, the line voltage is mistakenlyconnected to these terminals, the heat pump manager will bedestroyed. NOTE

For installation work on the switch box, ensure that the mains cable and signal cables are inserted separately into the switch box. The specially arranged switch box inlets must be used forthis purpose (see Fig. 7.4 on page 7). The mains cables and signal cables must also always be laidseparately in the switch box during wiring work.Fig. 7.4:Cable inlet switch box

7.5.2 Electrical installation work

1) The four-core electrical supply cable for the heat pumppower part is fed from the heat pump electricity meter intothe heat pump via the utility company blocking contactor(if required) (for supply voltage, see heat pump manual).The mains cable is connected to the heat pump contactplate via terminals X1: L1/L2/L3/PE. CAUTION!

Ensure that there is a clockwise rotating field: With incorrectwiring the starting of the heat pump is prevented. Acorresponding warning is indicated on the display of the heatpump manager (adjust wiring).An all-pole disconnecting device with a contact gap of at least3 mm (e.g. utility company blocking contactor or power contac-tor) and an all-pole circuit breaker with common tripping for allexternal conductors must be installed in the power supply forthe heat pump (tripping current and characteristic in compli-ance with the device information).2) The three-core supply cable for the heat pump manager(heating controller N1) is fed into the heat pump. Connec-tion of the control cable to the contact plate of the heatpump via terminal X2: L/N/PE.The (L/N/PE~230 V, 50 Hz) supply cable for the heat pumpmanager must have a continuous voltage. For this reason,it should be tapped upstream from the utility companyblocking contactor or be connected to the household cur-rent, as important protection functions could otherwise belost during a utility block.3) The utility company blocking contactor (K22) with maincontacts and an auxiliary contact must be designed andprovided by the customer in accordance with the heatpump output.The NO contact of the utility company blocking contactoris looped from the terminal strip X3/G to the plug-in termi-nal X3/A3. CAUTION! Extra-low voltage!4) The contactor (K20) for the immersion heater (E10) ofmono energy systems (HG2) should be dimensioned ac-cording to the radiator output and must be supplied by thecustomer. It is controlled (230 V AC) by the heat pumpmanager via terminals X2/N and X2/K20.5) The contactor (K21) for the flange heater (E9) in the do-mestic hot water cylinder should be dimensioned accord-ing to the radiator output and must be supplied by the cus-tomer. It is controlled (230 V AC) by the heat pumpmanager via terminals X2/N and X2/K21.6) The contactors mentioned above in points 3, 4 and 5 areinstalled in the electrical distribution system. 7) All installed electric cables must have permanent wiring.

7.5.3 Connection of electronically

regulated circulating pumps Electronically regulated circulating pumps have high startingcurrents, which may shorten the service life of the heat pumpmanager. For this reason, a coupling relay is installed or must beinstalled between the output of the heat pump manager andthe electronically regulated circulating pump. This is not neces-sary if the permissible operating current of 2 A and a maximumstarting current of 12 A are not exceeded in the electronicallyregulated circulating pump or if express approval has been is-sued by the pump manufacturer. CAUTION!

It is not permitted to connect more than one electronicallyregulated circulating pump via a relay output. 8 Commissioning

8.1 General Information

To ensure that commissioning is performed correctly, it shouldonly be carried out by an after-sales service technician author-ised by the manufacturer. This may be a condition for an addi-tional guarantee (see "Warranty service").

The following items must be checked prior to commissioning: All of the heat pump connections must be installed as de- scribed in chapter 7. The heat source system and the heating circuit must havebeen filled and checked. The dirt trap must be inserted in the brine inlet of the heat pump. All valves that could impair proper flow in the brine andheating circuits must be open. The heat pump manager must be adapted to the heating system in accordance with the controller's operating in-structions.

8.3 Commissioning procedure

The heat pump is commissioned via the heat pump manager. CAUTION!

Start-up must be performed in accordance with theinstallation and operating instructions of the heat pumpmanager.www.glendimplex.de 452237.66.49a · FD 0108 EN-9 WI 35TU - WI 45TU English 9 Cleaning / maintenance

To prevent faults due to sediment in the heat exchangers, caremust be taken to ensure that no impurities can enter either theheat source system or the heating system. In the event that op-erating malfunctions due to contamination occur nevertheless,the system should be cleaned as described below.

9.2 Cleaning the heating system

The ingress of oxygen into the heating water circuit may resultin the formation of oxidation products (rust), particularly if steelcomponents are used. These enter the heating system via thevalves, the circulating pumps and/or plastic pipes. A diffusion-resistant installation is therefore essential, especially with re-gard to the piping of underfloor heating systems. NOTE

We recommend the installation of a suitable corrosionprotection system to prevent the formation of deposits (e.g.rust) in the condenser of the heat pump.Residue from lubricants and sealants may also contaminate theheating water.In the event of severe contamination leading to a reduction inthe performance of the liquefier in the heat pump, the systemmust be cleaned by a heating technician.Based on current information, we recommend using a 5 %phosphoric acid solution for cleaning purposes. However, ifcleaning needs to be performed more frequently, a 5 % formicacid solution should be used.In both cases, the cleaning fluid should be at room tempera-ture. We recommend flushing the heat exchanger in the direc-tion opposite to the normal flow direction.To prevent acidic cleaning agents from entering the heatingsystem circuit, we recommend connecting the flushing devicedirectly to the flow and return of the liquefier of the heat pump.It is then important that the system be thoroughly flushed usingappropriate neutralising agents to prevent any damage frombeing caused by cleaning agent residue remaining in the sys- tem. Acids must be used with care and the regulations of the em- ployers liability insurance associations must be adhered to. The instructions of the cleaning agent manufacturer must al-ways be observed.

9.3 Cleaning the heat source

The supplied dirt trap must be inserted in the heat source inletof the heat pump to protect the evaporator against the ingressof impurities.The filter sieve of the dirt trap should be cleaned one day afterstart-up. Further checks must be set according to the level ofdirt. If no more signs of contamination are evident, the filter canbe removed to reduce pressure drops.

9.4 .Water quality requirements

Irrespective of any legal regulations, the ground water shouldnot contain any substances that could form deposits. Iron(< 0.2 mg/l) and Manganese (< 0.1 mg/l) limit values must beadhered to to prevent iron ochre sedimentation from forming inthe heat source system.The use of surface water or water containing salt is not permis-sible. Your local water utility can provide you with general infor-mation regarding the possible use of ground water. Water anal-yses are carried out by specially-equipped laboratories. Irrespective of any legal regulations, a water analysis must becarried out to establish conclusively whether the ground wateris compatible for the evaporator of a heat pump (see table). If one characteristic is negative “-” or two characteristics are “0”, the water quality is not sufficient for the heat pump.If the necessary water quality is not achieved or if this cannot beguaranteed long-term, we recommended installing a brine-to-water heat pump equipped with an intermediate circuit.
