2.2 – Operation of the Heat Pump
The Heat Pump is a closed and pressurised system in which the refrigerant serves as the medium for transferring energy.
A safety pressure switch is used on the refrigeration circuit, it is located on the high pressure part of the circuit at the output of the compressors. It is a dry contact that when the pressure becomes too high (>31 bar) opens. Once opened, it cuts the power to the compressors, independently of the electronics and thus protects all circuit components.
The evaporator (e) is a cooling exchanger which draws calories from the air. The humidity in the air condenses on contact with the cold surface, and forms condensation (evacuation in (i)).

3.1.1.2 – Condensates drainage
When the appliance is operating in frost protection mode, the condensed water must be drained off. In order for the condensates to drain properly, the drainage trough and hole must be clean and free of all debris (leaves, grass, etc…). If the condensates drainage pipe is connected to the rainwater runoff system, it is advised to use a siphon. Do not use any tools to remove ice (risk of damage to the heat exchanger). The Heat Pump is delivered with a flexible and transparent condensates drainage pipe (Ø20/25mm) which does not drain outdoors. Before activation of the appliance, it is mandatory to connect this flexible pipe to one of the two holes provided for this purpose:
– Remove the back panel of the appliance. – Position the flexible hose in its chosen place after having
drilled a hole in the grommet.
a – Draining from underneath the Heat Pump
This solution is recommended to minimise the risk of ice at the condensates drainage point.
b – Draining from the back of the Heat Pump
Is an acceptable solution but in this case an external heater cable (Ref. 751004) needs to be connected. Please refer to § «Heater cable for external condensates drainage» as well as the instructions provided with the heater cable itself.

3.1.1.4 – Protection screen for the finned heat exchanger
The plastic screen which protects the finned heat exchanger during transport may be removed once the Heat Pump is in position in its definitive installation site. To remove the plastic screen, simply cut it away from its attachment points. There is always a risk of damage to the fins from external factors (for example, being close to a well-frequented walkway or thoroughfare), therefore, it is preferable to keep the plastic screen in place. Caution: The fins are fragile and sharp. Make sure that the air passages are kept clean and clear of any blockages (take care not to bend the fins while doing so).
Never clean the finned heat exchanger with a high-pressure hose or any other pressurised cleaning equipment. This could damage the fins.

3.2 – Hydraulic installation
3.2.1 – Hydraulic connections on the installation

The Heat Pump is equipped with a hydraulic pressure relief valve set at 2.5 bars. A service pressure below this value should be maintained.

In order to ensure that fluids can circulate properly, it is advisable to check that the sizing of piping in the circuit is appropriate between the

Heat Pump and the Pilot.

All piping should be thermally insulated,

especially the connecting pipes from the Pilot

to the Heat Pump.

3.2.2 – Hydraulic connections : Heat Pump circuit
A sufficient flow rate should be ensured so that the range of temperature between the outlet and inlet of the Heat Pump does not exceed 8°C when the Heat Pump is operating at full power (take a temperature measure when the HRC70 Heat Pump is in heating mode and the system is fully functioning) :
The hydraulic connection section between the Heat Pump and the Pilot must be sufficient.
Using the tables provided in the hydraulic pilot installation manual, determine the minimum inner diameter of the connection of piping needed depending on the distance which separates the Heat Pump and the Pilot.

Make sure that all sections of piping are equipped with functional and accessible air valves.

The Heat Pump’s hydraulic connection to the Pilot can be done using steel, copper, or reticulated polyethylene pipes with a minimum equivalent diameter of 1”.

The hydraulic kit must be installed using flexible piping on the water inlet and outlet points of the Heat Pump in order to prevent any vibrations from being transmitted to the heating system.

3.2.3 – Heat Pump and Pilot pressure-relief valves
The Heat Pump and the Pilot are both equipped with pressurerelief valves. The pressure-relief valve on the Heat Pump sets the maximum acceptable pressure in the installation (2.5 bars when hot). The maximum service pressure on the Heat Pump must, consequently be lower than 2.5 bars.
Example : If the Heat Pump is positioned 5m below the Pilot, the pressure reading on the Pilot would be 0.5 bars less than the real pressure of the water in the Heat Pump. In this case, the maximum service pressure for the Pilot would be 2 bars. Therefore it would be advisable to fill the heating circuit at an intermediary pressure (between 1 and 1.5 bars).
In case of operating with a back-up boiler, these pressure-relief
valves MUST be installed in addition to the ones which the boiler
is already equipped with.
The connections and the evacuation conduits for the pressure-relief valves must be made from materials which are resistant to high temperatures and corrosion.

3.2.4 – Desludging
The HRC70 Pilot has an integrated desludging function which collects oxides, limescale, and other particles which may become detached from the inner walls of the heating circuit. The lower part of the system is equipped with a sludge valve which should be briefly activated at least once per year (see § «Maintenance and repairs»). For underfloor heating installations, we would advise you to install a settling tank, which will complement the actions taken by the Pilot.

– MANUAL HRC70 HEAT PUMPS 17 – 20 – 25 KW – V3

3.2.5 – Heat Pump water inlet filter (supplied)
A filter 1”1/4 must be installed on the water inlet piping on the Heat Pump:
· Respect the direction of flow on the filter (arrow on the valve)
Clean the filter several times as soon as the Heat Pump circulator pump has been activated (make sure to switch off the Heat Pump circulator pump before cleaning).
· Clean the filter at least once per year.
3.2.6 – Backflow prevention device
French law (articles 16.7 and 16.8 of the “Règlement Sanitaire Départemental”) stipulates that a type CB backflow prevention device must be installed. This device must be at different, nonregulated pressure zones, in accordance with the NF P 43-011 standard. This is also an obligatory requirement in other countries, which makes it important to verify the current laws and standards in effect in the country of installation and ensure that your installation is in compliance with them. The backflow prevention device is designed to prevent incoming heating water from entering the drinking water circuit. It must be connected to the mains drainage system.
3.2.7 – Purging the heating circuit
All necessary measures must be taken to ensure that the installation can be continuously degassed. Automatic air purging valves should be placed at each high point of the installation, and manual air purging valves should be installed on each radiator.
3.2.8 – Insulating the piping
Insulants must conform to the DTU 67.1 standard, or the current regulations in effect in the country of installation.
All visible piping and accessories (circulator pump, expansion vessel, valves, etc…) must be either insulated or placed in insulated sleeves. Remember to insulate the distribution manifolds and the inlet and outlet flow pipes to the underfloor heating circuit. Remember to insulate the piping which connects the Heat Pump to the Pilot.
3.2.9 – Expansion vessel
An expansion vessel needs to be installed onto the heating circuit. See Appendix A5 for information on proper sizing of the expansion vessel.
3.2.10 – Frost protection and water treatment
See Appendices A4 and A6.

3.3 – Electrical control connections
3.3.1 – Connecting to the Heat Pump control 3.3.1.1 – 2-core sheathed cable
The Heat Pump is pre-equipped with a non-polarised, 2-core sheathed cable (communication bus). This 10m cable is supplied with, and already connected to, the Heat Pump. It must be connected to the Pilot. If the connection needed is longer than 10m replace this cable with a 20m cable (Ref.753102)(Ref. 751005) or a 50m cable (Ref.754103) available as an option.

The HRC70 Heat Pump is CE-marked. It is compliant with French standard NF C15-100 as well as European standards EN 61000-3-3 and EN 61000-3-11, among others.
It is equipped with a progressive start-up, which limits the current at start- up to 45A in single-phase, and 60A in three-phase.
The power supply cable should be sized carefully according to the following factors:
– Maximum current required – Distance between the HRC70 Heat Pump and the power supply – overall protection – The neutral operating system
Make sure to strip the cable before placing it into the terminals, and make sure that the copper is in good condition.
A method of disconnection must always be installed in compliance with the installation rules.
If the power supply cable is damaged, it must be replaced by a qualified professional to avoid any risk of danger.
To access the terminals: remove the panel on the bottom left-hand side (2 screws) and open the electrical box (8 screws).
The electrical power supply cable should first be inserted through an exterior compression gland and then through a cable grommet on the electrical box.

3.4.2.1 – HRC70 Heat Pump : 230V single-phase connection

3.4.3 – Electrical protection for the compressors
The HRC70 Heat Pump is equipped with a progressive start-up device to limit the intensity of the current when the motor starts up, in compliance with the NF C-15-100 standard: 45A per phase in single-phase and 60A per phase in three-phase.

· Three-phase monitor relay for the HRC70 Heat Pump 17kW, 20kW and 25kW
A phase monitor relay is installed to prevent phase failure, which
could damage the compressors. If the phases are reversed, it will
stop the power supply to the Heat Pump.

CORRECT WIRING

INCORRECT WIRING

orange and green LED lights on

only green LED light on

In case of INCORRECT WIRING :

The electrical protection devices for the compressors constantly monitor the current and voltage. In case of overvoltage, under-voltage, or an abnormally high current, the compressor is stopped.
· Progressive start-up of the HRC70 Heat Pump when using a single-phase system
The progressive start-up device constantly monitors the compressor by measuring the current and voltage. In case of over-voltage, undervoltage, or an abnormally high current, the compressor is stopped.
How it works :
· The progressive start-up device controls the start-up phase until the motor reaches its stable operating speed.
· If the motor cannot start, it is because the power supply has been cut off by the progressive start-up device.
In order to protect the compressor, the motor will not be able to start-up again until 5 minutes after it has been stopped.
Start-up errors :
· If the compressor fails to start-up, 2 LEDs (orange and green) will be flashing to indicate the error (see § «Compressor start-up errors»).
· Progressive start-up of the HRC70 Heat Pump when using a 25kW three-phase system
The progressive start-up device also serves to control the phases (phase order or missing phase, which could damage the compressor).
If the order of phases is inversed or if there is a missing phase, the relay cuts the power supply supply to the compressor. This error is indicated by by the LED light flashing every second.
The progressive start-up device controls the power supply voltage. If the voltage is under 195V, the compressor is stopped or does not start-up. This error is indicated by the LED light flashing rapidly (10 flashes per second).
In case of a compressor error (over-current, short circuit, or error on the start-up device itself ) the error is indicated by an intermittent flashing of the LED (light on for 5 seconds, and then off for 5 seconds).

Caution: never work with live voltage!

If the phase order is reversed, or there is a phase missing, the relay cuts the power supply to the circuit board. A «BUS Err» error message will appear. This is indicated on the phase monitor relay by the orange light at the top being off and the green light at the bottom
being on. To correct the error, reverse the two phases on the mains
power terminal.

When the Pilot is switched on, a «BUS Err» error message will be displayed. Reverse the two phases on the three-phase power cable of the Heat Pump. Switch the power back on and check the voltage on each phase.

A3 – EU declaration
This device complies with international electrical safety standards IEC 60335-1, IEC 60335-2-40. The CE marking present on the device attests to its conformity with the following Community Directives, of which it meets the essential requirements:
· Low Voltage Directive (LV): 2014/35/EU. · Electromagnetic Compatibility Directive: (EMC): 2014/30/EU. · Ecoconception Directive for Energy-related products: 2009/125/
EC. · Limiting Hazardous Substances (ROHS): 2011/65/EU.
A4 – Frost protection
In cases where the HRC70 Heat Pump cannot operate (exterior temperature is outside of the operating range), and a back-up is authorised (boiler or electrical), it will automatically be protected from frost or ice as the circulator pump will operate and draw heat from the heating circuit which has its temperature maintained by the HRC70 Pilot’s electrical back-up or back-up boiler. The water temperature remains over 5°C. In all cases the piping must be properly insulated. Underground piping should be installed within protective guttering. However, in the case of installation without a back-up, or if the HRC70 Pilot or HRC70 Heat Pump is being switched off during the winter months (ex. accidental stop, secondary residence, etc…), an additional anti-freeze protection is necessary.
Apply glycol to the heating circuit (with a minimum concentration of 25% glycol) or make sure to have hydraulic circuit draining measures in place for the HRC70 Heat Pump and its accessories (described below).
Diagram for draining equipment
Ensure that the HRC70 Heat Pump is drained.

A5 – Sizing the expansion vessel
– For a heating installation with radiators: The expansion vessel equipping the boiler may be sufficient. Always check that the capacity of the existing expansion vessel corresponds to the total volume of the installation (take into account the 60L needed for the HRC70 Pilot tank when calculating the total volume of the installation without forgetting the volume of a buffer tank, if applicable).
– Sizing the expansion vessel: The volume of the expansion vessel which is required for the HRC70 Heat Pump depends on the height of the installation. You will need to adjust the pre-charged pressure of the expansion vessel and check that the capacity of the vessel corresponds to the total volume of the installation:

(1) : Deflate and check pressure in expansion vessel if necessary.
(2) : As a guideline, take into account: ·11 litres per kW heating capacity for steel radiators + 60 liters for HRC70 Pilot + buffer tank (if applicable)
· 13 liters per kW heating capacity for cast-iron radiators + 60 liters for HRC70 Pilot + buffer tank (if applicable)
· 17 liters per kW heating capacity for underfloor heating + 60 liters for HRC70 Pilot + buffer tank (if applicable)
Or, if known, use the exact volume.
Example · Installation with 12kW cast-iron radiators · Height of installation = 10m · Frost/ice protection using 25% glycol
Total volume of installation = 12 x 13 + 60 = 216 liters 1 liter of expansion vessels covers 11,6 liters of the volume of the installation, so here you would need an expansion vessel with a minimum volume of 18 liters (216 / 11,6).

Note1: The values given here are for a radiator installation (water
at 80°C). For use with an underfloor heating installation, multiply these values by 2.
Note 2 : The concentration of monopropylene glycol should not
be less than 25%.

A6 – Treatment of the water in the heating circuit
It is MANDATORY to read the additional document concerning the quality of water used for filling the installation.This document is included with this manual as well as in the packet with the warranty information.
This document also contains information which is PERTINENT to the WARRANTY of the material.
A6.1 – Preparing the hydraulic circuit (rinsing)
Before installing the HRC70 Pilot and the HRC70 Heat Pump, it is necessary to rinse the installation with an appropriate product. This permits the elimination of all traces left from soldering, soldering fluxes, grout, grease, sludge, metallic particles, etc..in radiators, underfloor heating, etc… This prevents any of the abovementioned waste from getting into the HRC70 Heat Pump heat exchanger, or from obstructing the filter installed on the incoming water inlet.
A6.2 – Filling water
The materials used for producing a heating circuit are of different natures. Instances of corrosion may occur through galvanic coupling in both new and existing installations. The filling of the heating circuit must be done only with untreated water (no water softener) from the drinking water network. Filling with water from any other source (well water, rain water etc…) will render the warranty null and void.
A6.3 – Treatment of the heating circuit
Central heating installations must be cleaned in order to eliminate debris (copper, filings, soldering waste) related to the set-up of the installation or from chemical reactions between the metals.
Futhermore, it is important to protect the central heating installations from risks of corrosion, limescale, and microbiological development through use of a corrosion inhibitor which is suitable for all kinds of installations (steel or cast-iron radiators, PEX underfloor heating).
PRODUCTS USED FORTHE TREATMENT OF HEATING WATER MUST BE APPROVED BY THE LOCAL OR NATIONAL PUBLIC HYGIENE AND HEALTH AUTHORITY.
We recommend the use of products in the SENTINEL range for preventative and curative treatment of the heating circuit. · For new installations : (less than 6 months old):
– Clean the installation with a universal cleaner to eliminate the debris from the installation (copper, fibres, soldering fluxes) Example : SENTINEL X300 or SENTINEL X800.
– Throughly rinse the installation until the water runs clear, with no traces of impurities left.

– Protect the installation against corrosion with a corrosion inhibitor, example: SENTINEL X100. Or against corrosion and freezing with an inhibitor with an anti-freeze additive. Example : SENTINEL X500 or SENTINEL R600.
· For existing installations:
– Desludge the installation with a desludging product to eliminate any sludge from the installation. Example : SENTINEL X400 ou SENTINEL X800.
– Throughly rinse the installation until the water runs clear, with no traces of impurities left.
– Protect the installation against corrosion with a corrosion inhibitor, example: SENTINEL X100. Or against corrosion and freezing with an inhibitor with an anti-freeze additive. Example : SENTINEL X500 or SENTINEL R600.
Corrosion inhibitor :
– protects against the formation of limescale
– prevents «pinhole» type corrosion
– prevents, in new installations, the formation of sludge and the proliferation of bacteria (in low temperature networks: algae)
– prevents the formation of hydrogen
– eliminates the sound of the generators
Treatment products from other manufacturers can be used if they guarantee that the product is appropriate for all the materials used in the appliance and offers efficient resistance to corrosion. To find this information refer to their user manual.
A6.4 – Protection from freezing
In cases where the HRC70 Heat Pump cannot operate (exterior temperature is outside of the operating range), and a back-up is authorised (boiler or electrical), it will automatically be protected from frost or ice as the circulator pump will operate and draw heat from the heating circuit which has its temperature maintained by the HRC70 Pilot’s electrical back-up or back-up boiler.
However, in the case of installation without a back-up, or if the HRC70 Pilot or HRC70 Heat Pump is being switched off during the winter months (ex. accidental stop, secondary residence, etc…), an additional anti-freeze protection is necessary to prevent having to drain the hydraulic circuit of the Heat Pump located outside of the building.
For anti-freeze product, use «monopropylene glycol» with an added corrosion inhibitor.

Do not use mono-ethylene glycol (toxic product)

Choose the % of glycol based on the minimum exterior temperature to protect the water circuit from freezing (the concentration should not be under 25%) :

Exterior temperature (°C) % de glycol needed

-10 -15 -20 -25 25 30 35 40

– MANUAL HRC70 HEAT PUMPS 17 – 20 – 25 KW -V3

29

When using a concentrated protect which needs to be diluted with water, mix the water+anti-freeze+inhibitor mixture together prior to inserting it into the installation.
RENDERING THE WARRANTY NULL AND VOID
All deterioration of the appliance due to an inappropriate quality of water and/ or the presence of corrosion in the absence of treatment products as described above, and/or an improper purging of air of the installation will render the warranty to be null and void.
· Regularly check the pH level and % of glycol in the installation. ·Never top-up the glycol in your installation without measuring the pH to check that the drop in glycol % is not due to a deterioration of the glycol. ·When the pH is acidic (<7) replace all of the glycol after having already drained and rinsed the installation.
