1.4 Energy-efficient use of the heat

pump By operating this heat pump, you are helping to protect the en-vironment. A prerequisite for energy-efficient operation is thecorrect design of the heat source system and heating system.It is particularly important for the efficiency of a heat pump tokeep the temperature difference between heating water andheat source as small as possible. For this reason, it is advisableto design the heat source and heating system very carefully. Atemperaturedifference of approximately one Kelvin (1 °C) in-creases the power consumption by around 2.5 %. When de-signing the heating system, it should be borne in mind that spe-cial consumers such as domestic hot water preparation shouldalso be taken into consideration and dimensioned for low tem- peratures. Underfloor heating systems (panel heating) are optimally suited for heat pump use on account of the low flowtemperatures (30 °C to 40 °C). It is important to ensure that the heat exchangers are not con-taminated during operation, as this increases the temperaturedifference, which in turn reduces the COP.When set correctly, the heat pump manager is also an essentialfactor in the energy-efficient use of the heat pump. Further in-formation can be found in the heat pump manager operatinginstructions. 2 Intended use of the heat pump

2.1 Area of application

The air-to-water heat pump is intended exclusively for heatingor, depending on the device, also cooling heating water. It canbe used in new or existing heating systems.The heat pump is suitable for mono energy and bivalent opera-tion.During continuous operation, proper defrosting of the evapora-tor must be guaranteed by maintaining a heating water returntemperature of more than 18 °C.The heat pump is not designed for the increased heat con-sumption required when a building is being dried out. For thisreason, the additional heat consumption should be met usingspecial devices provided by the customer. For drying out abuilding in autumn or winter, it is advisable to install a secondheat generator (e.g. an electric heating element available as anaccessory). NOTE

The device is not suitable for operation with a frequencyconverter.

2.2 Operating principle

Heating Surrounding air is drawn in by the fan and fed through the evap-orator (heat exchanger). The evaporator cools the air, i.e. ex-tracts heat from it. This extracted heat is then transferred to theworking medium (refrigerant) in the evaporator.The heat is brought to a higher temperature level by increasingits pressure with the aid of an electrically driven compressor. Itis then transferred to the heating water via the liquefier (heatexchanger).Electrical energy is used to raise the temperature of the heatfrom the environment to a higher level. Because the energy ex- tracted from the air is transferred to the heating water, this type of device is referred to as an air-to-water heat pump.The main components of an air-to-water heat pump are theevaporator, fan and expansion valve, as well as the low-noisecompressor, liquefier and the electrical control system.At low ambient temperatures, humidity accumulates on theevaporator in the form of frost, reducing the transfer of heat.Uneven accumulation during this process does not indicate afault. The evaporator is defrosted automatically by the heatpump as required. Under certain atmospheric conditions,steam may be emitted from the air outlet. Cooling (device-dependent) The functions of the evaporator and the liquefier are reversed inthe “Cooling” operating mode.The heating water transfers its heat to the refrigerant via the liq-uefier, which is now functioning as an evaporator. The refriger-ant is brought to a higher temperature level using the compres-sor. Heat is transferred to the surrounding air via the liquefier(which, in heating operation, functions as an evaporator).EN-4 452163.66.68 · FD 0010 www.glendimplex.de English HPL 6S-TU(R)W 3 Scope of supply

The heat pump is of compact design and the scope of supply includes the components listed. The refrigeration circuit is "hermetically sealed" and contains the fluorinated refrigerant R410A included in the Kyoto proto- col. Information on the GWP value and CO

equivalent of the refrigerant can be found in the chapter Device information. The refrigerant is CFC-free, non-ozone depleting and non-combus- tible

The switch box is located in the heat pump. After the two screws shown have been loosened, the cover can be removed. The switch box contains the control elements for the compres- sor, fan and the controller for the electronic expansion valve. The supply connections (protected with a cover) are located on the bottom of the switch box.

3.3 Hydro-tower HWK 332Econ5S

with heat pump manager The hydro-tower with heat pump manager included in the scope of supply must be used to operate the (reversible) air-to- water heat pump. The hydro tower constitutes the interface between a heat pump and the heat distribution in the building. The hydro tower contains all hydraulic components required between heat gen- eration and heat distribution with an unmixed heating circuit. A dual differential pressureless manifold with a buffer tank allows an energy-optimised hydraulic integration of the heat genera- tor and the heat distribution. The integrated heat pump manager is a convenient electronic regulating and control device. It controls and monitors the en- tire heating system based on the outdoor temperature or room temperature, as well as domestic hot water preparation and safety systems. The sensor for outside temperature to be mounted on-site incl. fixing materials is included with the heat pump and hydro- tower unit. The functions and usage of the hydro-tower are described in the operating instructions supplied. Cover supply connection terminalswww.glendimplex.de 452163.66.68 · FD 0010 EN-5 HPL 6S-TU(R)W English 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. 5Transport ATTENTION!

When transporting the heat pump, ensure that it is not tiltedmore than 45° (in any direction).Transport to the final installation location should be carried outwith a pallet. The basic device can be transported with a lifttruck, hand truck or by means of 3/4" pipes fed through theholes in the base plate or frame. 6 Installation

The device should always be installed on a permanentlysmooth, even and horizontal surface. The entire frame shouldbe in direct contact with the ground in order to ensure an ade-quate soundproof seal and to prevent the water-bearing com-ponents from becoming too cold. If this is not the case, ad-ditional insulation measures may be necessary. Furthermore,the heat pump should be set up so that the air outlet directionof the fan is perpendicular to the main wind direction to allowunrestricted defrosting of the evaporator. The heat pump is de-signed for installation on even ground. In the case of differentconditions (e.g.: installation on a platform or flat roof) or there isa greater risk of the heat pump tipping over (due to an exposedposition or high wind exposure), additional protection againsttipping over must be provided. The responsibility for the heatpump installation lies with the specialist system constructioncompany. During the installation, local requirements such asbuilding regulations, static load of the building, and wind expo-sure must be accounted for. It must be possible to carry out maintenance work without hin-drance. This is ensured when observing the distances to solidwalls as shown in the figure.The specified dimensions are valid for stand-alone installationonly. ATTENTION!

Do not restrict or block the area around the air intake or outlet. ATTENTION!

Observe country-specific building regulations! ATTENTION!

For installation close to walls the physical influences of thebuilding must be considered. No windows or doors should bepresent in the area surrounding the air outlet of the ventilator. ATTENTION!

In cases of installation close to a wall, there may be moresediment in the air inlet and outlet areas due to the air current.The colder outside air outlet should discharge in such a way asto not increase the heat losses in heated neighbouring rooms. ATTENTION!

Installation in a hollow or in an inner courtyard is notpermitted because cooled air collects at ground level and isdrawn in again by the heat pump during lengthy operation.EN-6 452163.66.68 · FD 0010 www.glendimplex.de English HPL 6S-TU(R)W

Condensed water that forms during operation must be drainedoff frost free. To ensure proper drainage, the heat pump mustbe mounted horizontally. The condensate pipe must have aminimum diameter of 50 mm and must be fed into a sewer insuch a way that it is safe from frost. Do not discharge the con-densate directly into clearing tanks or cess pits. The aggressivevapours and a condensate pipe laid in an area which is notfrost-free can destroy the evaporator. ATTENTION!

The frost line can vary according to the climatic region. Theregulations of the countries in question must be observed. 7 Assembly

The following connections need to be established on the heatpump:Flow and return of the heating system Control lines to the heat pump managerVoltage supplyCondensate drainAll 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.

7.2 Connection on heating side

The heating system connections on the heat pump are to bemade inside the device. Refer to the device information for theconnection sizes. Route the connection hoses out of the devicein a downwards direction. An optional pipe kit is available as anaccessory, which can be used to lead the connections out tothe side. Use a spanner to firmly grip the transitions when con-necting 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 theliquefier 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. Frost lineCondensate drainFlow and returnElectric cablesHeat pump0,20 mControl and main cables Opening the cover panels Closing the cover panelsPipe kitoptionalwww.glendimplex.de 452163.66.68 · FD 0010 EN-7 HPL 6S-TU(R)W English 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. ATTENTION!

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. NOTE

The notes/settings in the instructions of the heat pump manager must always be observed and carried out accordingly; not doing so will lead to malfunctions. 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. If the minimum heating water flow rate is not reached, the heat pump is blocked. The nominal flow rate is specified depending on the max. flow temperature in the device information and must be taken into account during planning. For return temperatures under 30 °C, the flow must be designed for the nominal conditions. The specified nominal flow rate (See "Device information" on page 14) must be guaranteed in every operating status. An in- stalled flow rate monitoring sensor is used only for switching off the heat pump in the event of an unusual and abrupt drop below the minimum heating water flow rate and not for moni- toring and safeguarding the nominal flow rate. Frost protection On heat pump systems where protection from frost cannot be guaranteed, there must be an option for draining the system (see figure). The frost protection function of the heat pump manager is active whenever the heat pump manager and the heat circulating pump are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the sys- tem has to be drained. 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 suita- ble frost protection.

7.3 Electrical connection

A standard five-core cable is used for connecting the heatpump to the power supply.The cable must be provided by the customer. The conductorcross section is selected in accordance with the power con-sumption of the heat pump (see appendix Device information)and the applicable VDE (EN) and VNB regulations.An all-pole disconnecting device with a contact gap of at least3 mm (e.g. utility blocking contactor or power contactor) as wellas a 3-pole circuit breaker with common tripping for all externalconductors must be installed in the power supply (tripping cur-rent in compliance with the device information). The relevant components in the heat pump contain an internaloverload protection. When connecting, ensure that the incoming supply has a clock-wise rotating field.Phase sequence: L1, L2, L3. ATTENTION!

Ensure the rotary field is clockwise when connecting themains cables (if the rotary field is not clockwise, the heatpump will not work properly, is very loud and may causedamage to the compressor).The control voltage is supplied via the heat pump manager.A 3-pole line must be laid for this in accordance with theelectrical documentation. Further information on the wir-ing of the heat pump manager is available in the heat pumpmanager operating instructions.A shielded communication line (J-Y(ST)Y ..LG) (not includedin the scope of supply) connects the heat pump managerwith the WPIO controller installed in the heat pump. Moredetailed instructions can be found in the heat pump man-ager operating instructions and in the electrical documen-tation. ATTENTION!

The communication cable is necessary for the function of air-to-water heat pumps in outdoor installation. It must beshielded and laid separately from the mains cable

7.3.1 Demand sensor connection

The demand sensor R2.2 is included with the heat pump man-ager. It must be connected (Cap. 3.2 on page VIII). NOTE

The return sensor R2 installed in the heat pump is active whenthe compressor is running and must not be disconnected 8 Commissioning

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 warranty (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. All valves which could impair the proper flow of the heating water in the heating circuit must be open. The air intake and air outlet paths must be clear. The fan must turn in the direction indicated by the arrow. The settings of the heat pump manager must be adapted to the heating system in accordance with the latter's op-erating instructions. Ensure that the condensate drain functions properly.

The heat pump is commissioned via the heat pump manager.Settings should be made in compliance with the HPM's instruc-tions.At heating water temperatures below 7 °C, commissioning isnot possible. The water in the buffer tank must be heated withthe second heat generator to at least 18 °C.To ensure problem-free commissioning, the following proce-dure is to be implemented:1) Close all consumer circuits.2) Ensure that the heat pump has the correct water flow.3) Use the manager to select the automatic operating mode.4) In the special functions menu, start the "Commissioning"program.5) Wait until a return temperature of at least 25 °C has beenreached.6) Now slowly reopen the heating circuit valves in successionso that the heating water flow rate is constantly raised byslightly opening the respective heating circuit. The heat-ing water temperature in the buffer tank must not be al-lowed to drop below 20 °C during this process. This en-sures that the heat pump can be defrosted at any time.7) When all heating circuits are fully open and a return tem-perature of at least 18 °C is maintained, the commissioningis complete. ATTENTION!

Operating the heat pump at low system temperatures maycause the heat pump to break down completely.www.glendimplex.de 452163.66.68 · FD 0010 EN-9 HPL 6S-TU(R)W English 9 Cleaning / maintenance

To protect the paintwork, avoid leaning anything against thedevice or putting objects on the device. External heat pumpparts can be wiped with a damp cloth and commercially availa-ble domestic cleaner. NOTE

Never use cleaning agents containing sand, soda, acid orchloride, as these can damage the surfaces.To prevent faults due to sediment in the heat exchanger of theheat pump, ensure that the heat exchanger in the heating sys-tem cannot be contaminated. Should operating malfunctionsdue to contamination still occur, however, the system shouldbe 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 complete piping. 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. We recommendequipping diffusion-open heating systems with anelectrophysical anti-corrosion system (e.g. ELYSATORsystem).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 air system

The evaporator, fan and condensate drain should be cleaned ofcontamination (leaves, twigs, etc.) before each new heating pe-riod. Do this by opening the heat pump as described inChapter . ATTENTION!

Before opening the device, ensure that all circuits aredisconnected from the power supply!To prevent the evaporator and the condensate tray from beingdamaged, do not use hard or sharp objects when cleaning.Under extreme weather conditions (e.g. snow drifts), ice mayform on the air intake and air outlet grids. If this happens, the ice must be removed from the vicinity of the air intake and air outlet grids to ensure that the minimum air flow is maintained.To ensure proper drainage from the condensate tray, it must beregularly inspected and cleaned, if necessary. 10 Faults / troubleshooting This heat pump is a quality product and is designed for trouble-free operation. Should a fault occur, however, it will be indi-cated on the heat pump manager display. In this case, consultthe "Faults and troubleshooting" page in the operating instruc-tions of the heat pump manager. If you cannot correct the faultyourself, please contact your after-sales service technician. ATTENTION!

Work on the heat pump must 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 heat pump must be dismantledby trained personnel. Observe all environmental requirementsregarding the recovery, recycling and disposal of materials andcomponents in accordance with all applicable standards. Par-ticular attention should be paid to the proper disposal of refrig-erants and refrigerant oils.EN-10 452163.66.68 · FD 0010 www.glendimplex.de English HPL 6S-TU(R)W 12 Device information 1 Type and order code
