Subject to change.
These instructions are for aproper installa­tion, adjustment and maintenance of the machine. It is therefore necessary to read carefully the instructions given below and to install, test and maintain the heat pump by technicians qualified by specific training. At the end of the warranty period, the ma­nufacturer assumes no responsibility for mechanical, hydraulic or electrical chan­ges. In the case of operations not expressly authorized, executed in violation of these instructions, the warranty will become void with immediate effect. During the installation must meet the speci­fic safety statements. Check that your mains supply correspond to the data of the heat pump (nameplate). These instructions and the wiring diagram of the heat pump should be stored with due care and, if necessary, be made available to the personnel responsible .
The manufacturer declines any responsibi­lity for damage to persons or property cau­sed directly or indirectly from failure to fol­low these instructions. The housing may only be opened by a qua­lified technicians.
Limitations and Guidelines The construction and the manufacture of heat pump meets all the requirements of European standards. (See EC Declaration of Conformity). The electrical connection of the heat pump must be performed in compliance with the applicable ASE, EN and IEC. Should also observe the connection conditions of the local energy supply
Warranty Conditions
Our performance guarantee shall lapse for damage due to:
misuse or non standard use
installation or commissioning
incorrect by the purchaser or from other.
Use of the system with pressure
excessive or outside the factory values
Failure to follow directions in the
instructions for use
The warranty for heat pumps for heating is 24 months from the date of delivery.For the rest, the condi­tions of sale, delivery and warranty in accordance with the order confir­mation.
Control Input
The units are delivered on a wooden pallet with an adequate protective packaging. Upon delivery, check the unit for shipping damage and that the bu­dget is complete.
If damage is found, they must be reported immediately to the transport document with a warning: "Acceptance qualified as a result of blatant corruption."
Given that overloading can cause serious damage to heat pump and plant heat source side, it is forbidden to operate the heat pump if the follo­wing conditions exist:
drying of the construction.
plant is not completed
(building shell).
windows and exterior doors
are not finished and closed.
In these cases it is necessary to pro­vide a heating pipeline. A functional heating or heat pump ready pose in according to the DIN EN 1264 should be only taking into account the above conditions. Furthermore, keep in mind that after the sizing of the heat pump for normal operation may not be possible to generate all the ne­cessary thermal power. Observe the following guidelines:
Comply with the regulations
and requirements of the ma­nufacturer of mortars for scre­ed coat!
Correct operation is only pos-
sible with a system installed in a workmanlike manner (the hydraulic, electrical, settings)! Otherwise, the screed coat may be damaged!
Low energy consumption use of the heating with heat pump
The decision to opt for a heating system with heat pump is a valuable contribution to protecting the environ­ment by reducing emissions and reduced use of primary energy. In order for the new heating system will work efficiently, note the following points:
L
The heating system with heat pump must be sized and installed with ca­re.
L
The lower is the flow temperature of the heating water side, the more efficient is the operation of the heat pump.
L
Give preference to a short-term in­tensive aeration of the premises. Compared to the windows always open in the tilted position, this imme­diate ventilation reduces the con­sumption of energy.

High Degree of Efficiency and Optimized Defrosting
Thanks to the correspondingly di­mensioned air heat exchanger as well as the unique defrosting system, the AEROTOP T heat pump is especially efficient and a cost-saver. This heat pump always exceeds the required degree of efficiency (coefficient) of
3.0 (COP at A2W35). Frost forms on the air exchanger, the evaporator, if the exterior temperature is less than 5°C. This results in ice formation and as a consequence reduced the heat exchange and with that the efficiency of the heat pump. The evaporator must be defrosted to remove this frost or ice. However, the defrosting process, carried out by the AEROTOP T by reversing the cooling circuit, is cumbersome since the heat pump does not yield any energy during the defrosting process but still uses electricity. However, this is frequently unnecessary since frost formation depends on the humidity in the air. Instead of the unnecessary defrosting at timed intervals, the AEROTOP T determines the correct time to defrost the unit using a progressive and well thought out logic with different per­formance parameters in the cooling circuit. Thanks to this procedure, the unit rarely requires any defrosting during winter, if any at all, which is a great advantage.
Cooling with AEROTOP TR
The purpose of heat pumps is primarily to supply a building with heat. However, the technology can also be used to cool a building in the summer. This involves actively generating the cooling energy through a process reversal of the heat pump. In case of distributor systems specifically designed for cooling (fan coil or simi­lar), the cooling capacity of the heat pump can be transferred optimally to the building. Cooling ceilings also have a good cooling capacity and comfort level. Floor heaters, however, are only partially suited and provide a limited cooling effect. Radiator heaters are unsuitable.
Cascade
Thanks to the new heat pump controller LOGON B WP61, it is possible to link and operate several heat generators of a system in a cascade arrangement. Cascades with up to 4 heat pumps, or a bivalent operation in combination with fossil heat generators are feasible. When using a cascade formation, the heat generators switch on or off depending on the current energy demand: If the currently running heat pump cannot satisfy the energy demand within a specific time, an additional heat pump/heat generator switches on.
Quiet Operation
Regardless whether installed indoors or outdoors, the air-water heat pump AEROTOP T is characterized by comparatively very low noise emissions. This is possible thanks to the high-performance fan, the very advantageous air routing, the noise--dampening insulation of the cladding, as well as the multi-dampened support of the cooling circuit. Additional noise insulation elements are available for most variants to reduce sound emissions further. AEROTOP T heat pumps are quiet and efficient. However, incorrectly integrating constructional components may result in undesired noise increases if the conditions are unfavorable.
Flexible and Space-Saving
Some air-water heat pumps are relatively bulky due to the required cross-sections for the air ducts or application options are severely limited. Thanks to the clever utilization of the geometric properties of the radial fan, AEROTOP T are among the most flexible, space saving air-water heat pumps. Especially noteworthy is the fact that the heat pump can be placed into the left or right corner of the utility room when not using the air ducts. The exhaust opening is easily moved on-site from the left to the right and even to the top without having to use any additional tools. The intake opening can also be selected as desired without special accessories. AEROTOP T heat pumps are also suitable for outdoors installation when using the corre­sponding accessories.

Enclosure and Special Components
The enclosure consists of a frame that is completely free of thermal bridging, sound dampened, and specifically developed for use with heat pumps. The cladding and panels feature a high-grade insulation to sound-dampen and thermally insulate the unit. A pedestal or base is not required since the feet of the unit feature a vibration-dampening design. All panels can be detached for easy access to the internal elements of the unit and for control or configuration tasks.
The high-performance radial fan
ensures the unit runs efficiently and quietly. The high performance cooling circuit is mounted on a vibration-dampened support and features a thermostatic expansion valve, filter dryer, inspection glass, high-pressure pressure controller with manual reset, and a low-pressure pressure controller with automatic reset function. The hermetic scroll compressor is mounted on a double vibration-dampened support. The evaporator consists of a large-area finned tube heat exchanger made from aluminum and copper; the condenser consists of a welded chromium steel high performance plate heat ex­changer. The environmentally friendly refrigerant R407C is used as the working medium. A flow monitor on the consumer side ensures trouble-free cooling for reversible heat pumps.
Operating the heat pump is prohibited if the following conditions exist:
Construction drying
System/unit used in unfinished
buildings
Windows or exterior doors
unfinished and locked.
These cases require the use of a specific construction heating system. Functional heating or surface-ready heating with the heat pump acc. to DIN EN 1264 is only permitted when complying with these conditions. Furthermore, it must be noted that the design of the heat pump concerning its standard operation may not yield the full extent of the required heat output. The following notes must be observed as well:
Comply with the corresponding
standards and rules of the floor/ screed manufacturer!
Proper function is only ensured
with a correctly installed system (hydraulics, electrical, settings)!
Deviations may damage the floor/ screed!

Setup and Connection Instructions
Safety, Transport and Installation
7
Transport
To avoid transport damages, the heat pump must remain packaged and on the wooden pallet and transported to its final installation location with a hand lift, pushcart, or similar equipment.
Make sure the heat pump does
not slip on the equipment used for transport.
Components and piping of the
cooling circuit, the heater side, and the heat source side may never be used for transport purposes.
Note the weight of the heat pump.
Make sure the water hoses and
electrical lines are not damaged during transport.
Only lift and transport the heat
pump at and with the unit's bottom panel.
Safety Information
Compliance with all rules and
instructions of all documentation, labels, type plates, and associated documents of the unit is mandatory.
Transport
When receiving the shipment, the
heat pump must be checked for completeness as per order confirmation .In case of damaged or missing material, the carrier must be informed in writing immediately.
Care and due diligence are
required during transport, setup, preparation, or when handling heavy materials that may damage the heat pump.
Make sure that towing ropes, belts,
or chains used for transport or installation do not damage the heat pump. Do not allow the heat pump to swing back and forth when lifting it up. Never tilt the heat pump more than 15° from its vertical axis.
The heat pump is affixed to a pallet
at the factory for transport and covered with a protective film to protect the unit from scratches. Do not remove the packaging until the heat pump is positioned at its final location.
Setup
Setup must be carried out carefully
and accurately.
AEROTOP T heat pumps can be
installed on a level interior floor without pedestal or base. If installed outdoors, a pedestal or base is required unless the substrate is very firm and can support the load.
The installation room must have at
least one exterior wall. Rooms with high humidity are unsuitable as installation locations for AEROTOP T heat pumps. A condensate drain must be available.
The heat pump must be set up on
a level ground and aligned with the adjustable feet. Make sure there is sufficient space to access the control panel and at the sides for inspections and maintenance.
Make sure the ground is able to
support the load of the heat pump and all accessories. The floor or ground must be free of dust and other foreign particles. If installing in the basement, make sure the selected installation position cannot be flooded.
The heat pumps may not be placed
on floating floorings.
Once moved to its final location,
the heat pump must be carefully unpacked and removed from the pallet. Protect heat pump from impact and other damaging forces!
Installation
The safety regulations and
schemes/diagrams must be strictly observed.
The accessories and additional
equipment must be installed by a trained service technician (heating contractor) as per the enclosed assembly and installation instructions.
The noise emissions of the
AEROTOP T heat pump are very low thanks to the sound-absorbing materials used to mount the mobile parts and the insulating cladding. The effective noise value depends also on the size of the installation room, the noise-absorbance or reflection of the materials in the room, as well as the possibility of the noise to spread and transfer via solid bodies, among others.
Air ducts, pipes, and electrical lines
must be attached to the masonry and not the heat pump.
All of these connections must be
established using flexible connections so that they can swing freely, especially when the compressor or evaporator starts up. Only then is it possible to avoid transference of sound from solid bodies to the building structure as well as line breakages.
Observe the checklist notes when selecting the installation site for the correct setup of an air-water heat pump
Setup and Connection Instructions
Hydraulic Connections, Condensate Drain

Heating System Hydraulic Connections
AEROTOP T heat pumps can be connected in any desired layout. The hydraulic connections require flexible ducts to avoid noise trans­ference from pipe openings and solid bodies to the distributor network and from there to the heating elements such as radiators, etc. The ducts can be directed from the right or left and are connected to the inside of the heat pump.
The ductwork must be carried out in such a way that pressure drops at the nominal volume flow do not exceed the available pressure since this would result in a reduction of the heat pump output. This means that ducts cannot have elbows that are too narrow.
Pipes and ducts must also be sufficient insulated to prevent unnecessary heat loss and the formation of condensate, which could damage the pipe and duct system or the installation location.
Dimensions
Heater flow Ø 1” (T07-T16), Ø 1 1/4” (T20-T35), flexible. Heater return Ø 1” (T07-T16), Ø 1 1/4” (T20-T35), flexible, Condensate Drain Ø 25/31mm, flexible.
For each heat pump we offer hydraulic standard schemes. The integration of these variants guarantee a safe and faultless operation.
The system must be thoroughly flushed before connecting to the heat pump.
Residues in the heat pipes lead to damages on the heat exchangers und to malfunction of the heat pump. Especially if there is no buffer storage it is recommended to a dirt trap in the heating return flow.
The water filled into the heating system must be handled in accordance with the rules and regulations of the relevant professional associations.
It is important to ventilate the heating system. If not the correct operation of the heat pump is affected. Therefore an exhauster must be provided. The compact heat pumps have an exhauster installed in the flow.
Condensate Drain
The condensate drain should be as close to the heat pump connection as possible. To prevent room air or canalization waste air from being sucked into the heat pump, the condensate drain must be connected airtight to the heat pump using a siphon with a min. height of 100 mm. The condensate drainage pipe cross-­section may not be reduced and must be at a continuous 2% incline to ensure water can be sufficiently drained.
Changing the Hydr. and Electr. Connections
Lines are connected at the left side of the unit by default. If the right side is preferred, the panels (1 and 2) can be switched with the panels from the left side. Ducts and cables are pulled to the other side inside of the unit and through the opening in panel 1.

Electrical Connections and Control Information
The electrical connections must be established in compliance with local rules and regulations. The current feed may exhibit a max. tolerance of 2% with this power intensity when a voltage of 10% exists. Do not connect the heat pump if the phase difference exceeds more than 2%. (EN 60439-1) Operating the equipment outside of the listed limit values will void the warranty. If necessary, please contact your local electricity company or utility. The internal wiring of the heat pump is carried out at the factory as listed on the electrical diagram included with the unit. The heat pump is equipped with an electrical supply box containing the components listed below.
An automatic cutout switch or a
3 phase, slow-blow fuse with neutral conductor must be provided externally in compliance with the technical requirements.
The low voltage cables (control)
may not be placed in the same cable conduits or ducts as the supply cables.
The exterior temperature sensor of
the controller must be attached to the outside wall of the building in a location protected from the after­ noon sun and other heat sources (open windows, chimneys, etc.). Northern and northeastern exposures are preferred.
If the room impact is to be
activated for a remote control, this control unit must be placed in a reference room (e.g. living room) where it cannot be influenced by an external heat source (e.g. stoves, heaters, air flow, etc.).

Checklist
Correct Installation of an Air-Water Heat Pump
AEROTOP T heat pumps are quiet and efficient. However, incorrectly integrating constructional components may result in undesired noise in­creases if the conditions are unfa­vorable. A careful assessment of the noise emissions is required when planning the installation of heat pump systems.
Noise reduction measures considered early on in the development process result in the fewest additional costs. Subsequent measures usually are extremely expensive and cumbersome to implement. [Heat Pump Manual, Federal Energy Agency, Switzerland] The following points apply to the interior and exterior installation of air-water heat pumps.
16
To be considered when installing an air-water heat pump
Each reflecting surface doubles the noise (acoustic power). One wall increases this value by +3dB, one corner by +6dB.
one corner by +6dB. Avoid solid-borne noise transmission by avoiding reflecting surfaces. Never route air intake or outlet into closed or partially closed spaces such as a corner, foyer, entrance area, covered patio, etc.
Rooms with reverberant or sound-reflecting floor coverings and walls increase the noise level.
Avoid rooms with reverberant or sound-reflecting floor coverings and walls. When installing the heat pump in a room with reverberant or sound-reflecting floor coverings and walls, reflections may increase the sound level. Cover one or two walls with noise-absorbing material if this is the case.
Adherence with the min. clearances reduces noise reflection and air short-circuits and improves airflow near the fan.
Make sure the min. distances and clearances to the air intake and outlet as well as the min. size of the light wells are applied. Avoid walls or flow barriers around the circumference of the heat pump to ensure air can reach the fan evenly. Less pressure losses = low peripheral speed = reduction of the fan noise.
Construction measures can reduce noise, plants cannot.
Use constructional measures to interrupt the flow of noise from the heat pump (direct noise propagation). Use solid walls, fences, palisades, etc. to reduce noise levels. Plants, however, do not reduce noise.
Consider different noise sensitivity levels.
Avoid placing the heat pump where it may cause problems due to its noise emission (bedrooms, living rooms, neighbors, etc.). Position heat pumps in areas where noise is less likely to be an annoyance. If installed indoors, do not install underneath or next to living or sleeping quarters.
Sound absorbing materials reduce noise.
Additional sound absorbing materials or measures must be planned for and used in cases where extreme noise reductions are desired or when installing model Forever GREEN 20C or later. Use only original accessories and spare parts. in extreme cases, it may be advisable to consult a noise expert.
Separation from the structure minimizes structure-borne sounds.
Always use flexible connections throughout: Flexible hoses and tubes for heat distribution, flexible electrical connections, sound isolation of the air ducts by using elastic sleeves or Compriband products.
Correct installation of pedestal or base reduces structure-borne sounds.
The base or ground must be level or made level and able to support the load of the equipment. Use the adjustable feet of the heat pump to level the equipment after installation.
Correct installation of the ducts reduces air and structure-borne noise transference.
All wall openings and ducts must be equipped with the corresponding noise-absorbing materials. Comply with the specified cross-sections and dimensions.
Avoid air short-circuits and airflow barriers.
Air intakes and outlets cannot be installed next to each other without using a separating wall. Avoid any airflow obstacles that favor an air short-circuit.
Always comply with all rules, regulations, and applicable laws.
Germany: Technical Instructions on Noise Switzerland: Noise Protection Ordinance
Be careful with dropping the washing
Dropping the washing from lived-in rooms to the place of installation of the heat pump can lead to noise transmission when unfavourably positioned.

Requirements for Initial Startup (Commissioning)
The initial startup of the AEROTOP T heat pump must be carried out by our qualified technicians or the warranty will become void.
Operating the heat pump is prohibited if the following conditions exist:
Construction drying
System/unit used in unfinished
buildings
Windows or exterior doors
unfinished and locked. These cases require the use of a specific construction heating system.
Functional heating or surface-ready heating with the heat pump acc. to DIN EN 1264 is only permitted when complying with these conditions. Furthermore, it must be noted that the design of the heat pump concerning its standard operation may not yield the full extent of the required heat output. The following notes must be observed as well: The corresponding rules and regulations of the floor/screed manu­facturer! Proper function is only ensured with a correctly installed system (hydraulics, electrical, settings)! Deviations may damage the floor/screed!
Ensure the following points are imple­mented and checked before the initial startup of the heat pump:
The control box is installed and
completely connected.
The heat pump is professionally
and completely installed (hydraulics and electrical).
All external system components
required for operating the heat pump (circulation pumps, three-way valves, sensors, etc.) are completely and professionally connected.
The hydraulic connections have
been established completely and professionally.
All sensors are professionally
installed, shielded, and positioned in the correct locations as outlined by the respective system scheme.
The heating system is profes-
sionally installed and has been flushed, charged, vented, and checked for leaks as per rules and regulations.
The electrical voltage meets the
requirements listed on the type plate of the heat pump.
All fittings are in operational position.
The following persons must be present to carry out the initial startup
process:
The planer; he or she must indicate
the operational parameters.
The installer; he or she is responsi-
ble for the functionality and settings of the hydraulic system.
The system maintainer (customer
or representative); he or she will be instructed in the operation and functions of the system.
If an initial startup is requested without all of these conditions having been met, ELCO rejects any responsibility for system malfunctions or other opera­tional problems. In this case, the system is operated at the risk and re­sponsibility of the owner.
Parameterization
The heat pump and the entire system is controlled with the integrated LOGON B WP61 controller. Please consult the system documentation for the correct parameter settings.
After the Initial Startup
After the initial startup is finished, the AEROTOP T heat pump does not require any additional interventions or adjustments to the controller.
Any desired heating temperature adjustments can be made in ac­cordance with the enclosed user manual for the LOGON B WP61 controller.
Controller Function
Different temperature sensors and measuring elements in the heat pump, at the exterior air, in the system, in the storage tank, in the hot water tank, and possibly also in the living quarters are used by the controller. If and as needed, the controller passes a heat demand signal to the heat pump.
The input of a heating curve is used to control and adjust heating tempera­tures. The heat pump as well as the system is controlled automatically. The system-relevant parameters are entered when commissioning the climate-based controller.
Heat Pump Upkeep
The AEROTOP T heat pump does not require any special upkeep. However, it is important to keep the system clean and in good working order. The specified leak checks must be carried out as well. From an energetic viewpoint, it is also recommended, es­pecially in case of a new construction, to have the heating parameters checked and optimized by a service technician during the second winter after the initial startup since the initial humidity has now evaporated from the building and the required heating output is less than initially.
Primary focus should be on keeping air intake and outlet free of dust and other foreign particles or objects. The air intake and outlet openings must be kept free of obstructions (e.g. leaves, vehicles, debris).
Only trained and authorized service technicians are permitted to service AEROTOP T heat pumps.
The warranty becomes null and void if the system or heat pump is serviced by other persons or companies that are not authorized to do so.
Error Messages
AEROTOP T heat pumps function without problems as long as the dif­ferent parameters do not deviate from the intended or specified values. If one or several of these parameters exceed the limit values, the controller depicts the corresponding error in plain text and stops the heat pump if required to protect the different components. The different error messages are described in the LOGON B WP61 user manual. The heat pump is released again with some errors (automatic acknowledgement) once the intended status has been reached again. It is also usually possible to release the heat pump manually.
In order to ensure reliable functionality of your system, we recommend purchasing a mainte­nance/service contract.
