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 energy consumersshould therefore be suitable for low flow temperatures. Raisingthe heating water temperature by 1 K corresponds to an in-crease in energy consumption of approx. 2.5 %. Low-temperature heating systems with flow tempera-tures between 30 °C and 50 °C are particularly well-suited forenergy-efficient operation. 2 Purpose of the Heat Pump

The brine-to-water heat pump is to be used exclusively for theheating of heating water. It can be used in new or previously ex-isting heating systems. A mixture of water and antifreeze (brine)is used as the heat transfer medium in the heat source system.Borehole heat exchangers, ground heat collectors or similarsystems can be used as the heat source system.

2.2 Operating Principle

The heat generated by the sun, wind and rain is stored in theground. This heat stored in the ground is collected at a low tem-perature by the brine circulating in the ground collector, groundcoil or similar device. A circulating pump then conveys the“heated” brine to the evaporator of the heat pump. There theheat is given off to the refrigerant in the refrigerating cycle. Thiscools the brine so that it can once again absorb thermal energyin the brine 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.Subsequently, the refrigerant is passed through the condenserwhere it transfers its heat energy to the heating water. Depend-ing on the set operating point (thermostat setting), the heatingwater is thus heated up to a max. of 62 °C.www.glendimplex.de 452235.66.22a · FD 0106 EN-3 SI 6TU - SI 18TU English 3Basic Device The basic device consists of a heat pump for indoor installationwired ready for use with metal casing, switch box and inte-grated heat pump manager. The refrigeration circuit is "hermet-ically sealed" and contains the fluorinated refrigerant R410A in-cluded in the Kyoto protocol. Information on the GWP valueand CO equivalent of the refrigerant can be found in the chap-ter Device information. The refrigerant is CFC-free, non-ozonedepleting and non-combustible.All components required for the operation of the heat pump arelocated on the control panel. An external temperature sensor including fixing accessories and a dirt trap are supplied with the heat pump. The supply for the load current and the control volt-age must be installed by the customer.The supply lead of the brine circulating pump (to be providedby the customer) must be connected to the control panel. If re-quired, a motor protection device and/or contactor must beprovided here.The customer must provide both the heat source system andthe brine circuit manifold.1) Liquifier2) Control panel3) Evaporator4) Compressor5) Filter dryer 6) Economizer7) Expansion valve 4 Accessories

4.1 Brine Circuit Manifold

The brine circuit manifold merges the individual collector loopsof the heat source system into a single main pipe which is con-nected to the heat pump. Integrated ball valves allow the indi-vidual brine circuits to be shut off for de-aeration purposes.

A remote control 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 operatingelement, this can also be used directly as a remote control.

4.3 Building management

technology 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 pump is controlled externally,an flow rate switch is required to prevent the compressorfrom being switched on when there is no volume flow.EN-4 452235.66.22a · FD 0106 www.glendimplex.de English SI 6TU - SI 18TU 5Transport A lift truck is suited for transporting the unit on a level surface.Carrying straps may be used if the heat pump needs to betransported on an uneven surface or carried up or down stairs.These straps can be passed directly underneath the woodenpallet. CAUTION!

The heat pump is not secured to the wooden pallet. CAUTION!

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

Do not use the holes in the panel assemblies for lifting thedevice! 6Set-up

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 entireframe should lie directly on the floor to ensure an adequatesoundproof seal. If supporting feet are used, the heat pumpmust be installed horizontally. In this case, the specified soundlevel can be up to 3 dB(A) higher, and additional sound insula-tion 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 and on each sideof the heat pump.Neither frost nor temperatures higher than 35°C must occur inthe installation location at any time of the year.

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

7.1 General Information

The following connections need to be established on the heatpump: Flow and return of the brine (heat source system) Flow and return flow of the heating system Temperature sensor Voltage supplywww.glendimplex.de 452235.66.22a · FD 0106 EN-5 SI 6TU - SI 18TU English

7.2 Heating System Connection

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 theliquifier could cause the heat pump to completely break down.Once the heating system has been installed, it must be filled,de-aerated and pressure-tested. CAUTION!

The maximum test pressure in the heating circuit and thebrine circuit is 6.0 bar (ü). This value must not be exceeded. Consideration must be given to the following when filling thesystem: Untreated filling water and make-up water must be of drinking water quality (colourless, clear, free from sedi-ments) Filling water and make-up water must be pre-filtered (pore size max. 5 µm).Scale formation in domestic hot water heating systems cannotbe avoided, but in systems with flow temperatures below 60 °C,the problem can be disregarded. With high-temperature heatpumps 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 followingstandard values should therefore be adhered to with regard tothe 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 2035For systems with an above-average specific system volume of50 l/kW, VDI 2035 recommends using fully demineralizedwater and a pH stabiliser to minimize the risk of corrosion in theheat pump and the heating system. CAUTION!

With fully demineralized water, it is important to ensure thatthe minimum permissible pH value of 7.5 (minimumpermissible value for copper) is complied with. Failure tocomply with this value can result in the heat pump beingdestroyed. Minimum heating water flow rate The minimum heating water flow rate through the heat pumpmust be assured in all operating states of the heating system.This can be accomplished, for example, by installing either adual differential pressureless manifold or an overflow valve. Theprocedure for adjusting an overflow valve is described in theChapter Start-Up. NOTE

The use of an overflow valve is only recommended for panelheating and a max. heating water flow of 1.3 m³/h. Systemfaults may result if this is not observed.The antifreeze function of the heat pump manager is activewhenever the heat pump manager and the heat circulatingpumps are ready for operation. If the heat pump is taken out ofservice or in the event of a power failure, the system has to bedrained. The heating circuit should be operated with a suitableantifreeze if heat pump systems are implemented in buildingswhere a power failure can not be detected (holiday home).

7.3 Heat Source Connection

The following procedure must be observed when connectingthe heat source:Connect the brine pipe to the heat pump flow and return. Thehydraulic integration diagram must be adhered to. CAUTION!

The supplied dirt trap must be inserted in the heat source inletof the heat pump to protect the evaporator against the ingressof impurities.The brine liquid must be produced prior to charging the system.The liquid must have an antifreeze concentration of at least25 % to ensure frost protection down to -14 °C.Only monoethylene glycol or propylene glycol-based antifreezemay be used.The heat source system must be de-aerated and checked forleaks. CAUTION!

The brine solution must contain at least a 25 % concentrationof a monoethylene glycol or propylene glycol-basedantifreeze, which must be mixed before filling. NOTE

If necessary, the operating range can be extended to a brineinlet temperature of -10 °C. In this case, the minimum brineconcentration must be adjusted to 30 %. (Freezingtemperature -17 °C) CAUTION!

The maximum test pressure in the heating circuit and the brine circuit is 6.0 bar (ü). This value must not be exceeded. NOTE

A suitable de-aerator (micro bubble air separator) must beinstalled in the heat source circuit by the customer.Total heat output in kWTotal alkaline earths in mol/m³ and/or mmol/lSpecific system volume (VDI 2035) in l/kW < 20 20 < 50 50 Total hardness in °dH < 50 2.0 16.8 11.2< 0.11

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 pag. 6. The only exception is the external temperature sensor included in the scope of supply of the heat pump (see Fig.7.3 on pag. 6) Fig. 7.2:Sensor characteristic curve NTC 10 Fig. 7.3:Sensor characteristic curve, standardised NTC-2 according to DIN 44574 External temperature sensor

7.4.2 Mounting the external 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. Mount on the external wall on the north or north-west side where possible 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 (apply 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 pressureless manifold function as an interface between the heat pump, the heating distribution system, the buffer tank and, in some cases, even the hot water cylinder. A compact system is used to sim- plify the installation process, so that a lot of different compo- nents do not have to be installed individually. Further informa- tion 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 must be installed in the immersion sleeve of the dual differential pressureless manifold.

7.5 Electrical connection

All electrical connection work must be carried out by a trained electrician or a specialist for the specified tasks in accordance with 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 pump works properly, the heat pump manager must remain con- nected to the power supply and the flow must be maintained through the heat pump at all times. The switching contacts of the output relay are interference- suppressed. Therefore, depending on the internal resistance of the measuring instrument, a voltage can also be measured when the contacts are open. However, this will be much lower than the line voltage. Extra-low voltage is connected to controller terminals N1-J1 to N1-J11; N1-J19; N1-J20; N1-J23 to N1-J26 and terminal strip X3; X5.1. If, due to a wiring error, the line voltage is mistakenly connected to these terminals, the heat pump manager will be destroyed

7.5.2 Electrical installation

1) The supply electric cable for the output section of the heat

pump (up to 4-core) is fed from the electricity meter of the heat pump via the utility blocking contactor (if required) into the heat pump Connection of the mains cable to the control panel of the heat pump via terminal X1: L1/L2/L3/ PE. An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contac- tor) and an all-pole circuit breaker with common tripping for all external conductors must be installed in the power supply for the heat pump (tripping current and characteris- tic in compliance with the device information). CAUTION!

Ensure that there is a clockwise rotating field: With incorrect wiring the starting of the heat pump is prevented. A corresponding warning is indicated on the display of the heat pump manager (adjust wiring).

2) The three-core electric supply cable for the heat pump

manager (heating controller N1) is fed into the heat pump . Connection of the control line to the control panel of the heat pump via terminal X2: L/N/PE. Details on the power consumption of the heat pump are listed on both the product information sheet and the type plate. The (L/N/PE~230 V, 50 Hz) supply cable for the heat pump manager must have a constant voltage. For this reason, it should be tapped upstream from the utility blocking con- tactor or be connected to the household current, as impor- tant protection functions could otherwise be lost during a utility block.

3) The utility blocking contactor (K22) with 3 main contacts

(1/3/5 // 2/4/6) and an auxiliary contact (NO contact 13/

14) should be dimensioned according to the heat pump

output and must be supplied by the customer. The NO contact of the utility blocking contactor (13/14) is looped from terminal strip X3/G to connector terminal X3/ A1. CAUTION! Extra-low voltage!

4) The contactor (K20) for the immersion heater (E10) of

mono energy systems (HG2) should be dimensioned ac- cording to the radiator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X2/N and X2/K20.

5) The contactor (K21) for the flange heater (E9) in the hot

water cylinder should be dimensioned according to the ra- diator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via termi- nals X2/N and X2/K21.

6) The contactors mentioned above in points 3, 4 and 5 are

installed in the electrical distribution system. The mains cable for the installed pipe heater must be laid and secured in accordance with the valid standards and regulations.

7) All installed electric cables must have permanent wiring.

8) The heat circulating pump (M13) is connected to terminals

9) The DHW loading pump (M18) is connected to terminals

10) The brine or well pump (M11) is connected to terminalsX2/

N and X2/M11 and PE.

11) The return flow sensor is integrated into the heat pumps

and is connected to the heat pump manager via the control line. The return flow sensor must be installed in the immer- sion sleeve in the manifold only when a dual differential pressureless manifold is used. The single-core wires are then connected to terminals X3/GND and X3/ R2.1. Bridge A-R2 (situated between X3/B2 and X3/1 when delivered) must then be moved to terminals X3/1 and X3/2.

12) The external sensor (R1) is connected to terminals X3/GND

13) The domestic hot water sensor (R3) is included with the

domestic hot water cylinder and is connected to terminals X3/GND and X3/R3.EN-8 452235.66.22a · FD 0106 www.glendimplex.de English SI 6TU - SI 18TU

7.5.3 Connecting an electronically

regulated circulating pump 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 start-up is performed correctly, it should only be carried out by an after-sales service technician authorised by the manufacturer. These measures can also include an addi-tional warranty under certain conditions (see Warranty).

The following items need to be checked prior to start-up: The heat pump must be fully connected, as described inChapter 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 and heating circuits must be open. The heat pump manager must be adapted to the heatingsystem in accordance with the controller’s operating in-structions.

8.3 Start-up Procedure

The heat pump is started up via the heat pump manager. CAUTION!

The heat pump must be started up in accordance with theinstallation and operating instructions of the heat pumpmanager.If an overflow valve is fitted to assure the minimum heatingwater flow rate, the valve must be set in accordance with the re-quirements of the respective heating system. Incorrect adjust-ment can lead to faulty operation and increased energy con-sumption. We recommend carrying out the followingprocedure to correctly adjust the overflow valve:Close all of the heating circuits that may also be closed duringoperation (depending on the type of heat pump usage) so thatthe most unfavourable operating state - with respect to thewater flow rate - is achieved. This normally means the heatingcircuits of the rooms on the south and west sides of the build-ing. At least one heating circuit must remain open (e.g. bath-room).The overflow valve should be opened far enough to producethe maximum temperature spread between the heating flowand return flow listed in the table below for the current heatsource temperature. The temperature spread should be meas-ured as close as possible to the heat pump. The heating ele-ment of mono energy systems should be disconnected duringstart-up.Heat sourcetemperatureMax. temperature spreadbetween heating flow and return flow From To-5 °C 0 °C 10 K1 °C 5 °C 11 K6 °C 9 °C 12 K10 °C 14 °C 13 K15 °C 20 °C 14 K21 °C 25 °C 15 Kwww.glendimplex.de 452235.66.22a · FD 0106 EN-9 SI 6TU - SI 18TU English 9 Maintenance and Cleaning

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. This oxygen enters the heating systemvia the valves, the circulating pumps and/or plastic pipes. It istherefore essential - in particular with respect to the piping ofunderfloor heating systems - that only diffusion-proof materialsare used. 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 case of severe contamination leading to a reduction inthe performance of the liquifier 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 either case, 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 flow of the liquifier. It is importantthat the system be thoroughly flushed using appropriate neu-tralising agents to prevent any damage from being caused bycleaning agent residue remaining in the system.Acids must be used with great care and all relevant regulationsof the employers’ liability insurance associations must be ad-hered to.The manufacturer's instructions regarding cleaning agent mustbe complied with at all times.

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 after-start-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. 10 Faults / Trouble-Shooting This heat pump is a quality product and is designed for trouble-free operation. In the event that a fault should occur, it will beindicated on the heat pump manager display. Simply consultthe Faults and Trouble-Shooting page in the operating instruc-tions of the heat pump manager.If you cannot correct the fault yourself, please contact yourafter-sales service technician. CAUTION!

Before opening the device, ensure that all circuits aredisconnected from the power supply!After disconnecting the power supply, always wait for at least 5 minutes to allow stored electric charges to dissipate. CAUTION!

Any work on the heat pump may only be performed byauthorised and qualified after-sales service technicians. 11 Decommissioning / Disposal Before removing the heat pump, disconnect it from the powersource and close all valves. The deinstallation of the heat pumpmust be performed by technical personnel. Observe all environ-mentally-relevant requirements regarding the recovery, recy-cling and disposal of materials and components in accordancewith all applicable standards. Particular attention should be paid to the proper disposal of refrigerants and refrigeration oils.EN-10 452235.66.22a · FD 0106 www.glendimplex.de English SI 6TU - SI 18TU 12 Device Information 1 Type and order code SI 6TU SI 8TU SI 11TU 2 Design
