4.1 – Operation
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 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 which must be drained regularly
during operation of the Heat pump (evacuation in ).
The condenser is a plated heat exchanger which allows to transfer the heat towards the heating water of the installation .
The operating range of the Heat pump ranges from an air temperature of -20°C to 40°C.
Note:
The Heat Pump is exclusively designed for heating purposes. It cannot be used for cooling. The manufacturer cannot be held responsible for any other usage of the appliance.

· A phase controller relay HTi70 three-phase 11 kW and 14 kW heat pump.
In order to prevent a phase fault or bad sequence -which could cause compressor damage- a phase controller relay is installed. It prohibits the power supply to the heat pump if phases are reversed.

Proper Wiring

Incorrect wiring

Amber and green lights on

Green light only on

In case of incorrect wiring :
Attention, never work under tension
If the order of the phases is reversed or if a phase is missing, the relay cuts the power supply to the electronic board. A «BUS Err» defect appears. On the phase controller relay, this is indicated by the absence of the orange light on the top and the green light on the bottom. To correct this fault situation, two phases must be reversed on the power terminal block general power cable. When the hydraulic driver is powered on, a «BUS fault» is displayed. Reverse two phases on the heat pump three-phase power cable. Power back on and check the voltage on each phase.

6 MAINTENANCE AND TROUBLESHOOTING
·In order to ensure the best performance results from your HTi70 Heat pump it should be subject to regular maintenance. ·An annual maintenance check is recommended to be carried out by a qualified professional on the hydraulic heating circuit. ·All work carried out on the refrigerant circuit must be done by a qualified professional with a category 1 certificate of aptitude. ·Always switch the appliance off before opening it.
6.1 – General information
After the appliance has been operating for a few days, it is advised to check that the water circuit is properly sealed.
Note: In case of maintenance work or decommissioning of an
appliance, please respect all environmental protection instructions concerning recovery, recycling, and disposal of consumables and components.
6.2 – Maintenance on the hydraulic circuit
Inspection of the water circuit consists of removing sludge, checking the filters, and stopping up any leaks that may have appeared. Clean or replace clogged or dirty filters. From time to time check that the condensates are draining properly.
6.3 – Maintenance of the Heat pump
The HTi70 Heat pump contains R290 refrigerant fluid. It is not subject to regulations concerning greenhouse gasses, and does not necessitate mandatory annual maintenance by a qualified professional. However, it is still recommended to carry out periodic (at least once per year) cleaning of the evaporator fins if it is obstructed by dust or leaves: this should be done using a vacuum cleaner or by spraying with water.
Never clean the finned heat exchanger with high-pressure cleaning equipment as it could damage the fins.

In case of repair work on the HTi70 Heat pump, the refrigerant circuit, or the electrical box, it is important to follow the following instructions: Any work on the refrigerant circuit must be undertaken by a qualified professional with a category 1 certificate of aptitude. 1. It is forbidden to release gas from the refrigerant circuit into the atmosphere, and it is obligatory to recover the refrigerant before undertaking any work on the circuit. The HTi70 Heat pump uses R290 refrigerant fluid. Given the flammable nature of this fluid, any work on the refrigerant circuit must be carried out using suitable equipment which complies with the current rules and regulations in effect. When handling the fluid (recovery, draining, or refilling), the appliance must be disconnected from the power supply. Do not smoke. Do not generate any flame (lighter, blowtorch) while handing the fluid. If work is necessary on the refrigerant circuit using a flame (blowtorch), the refrigerant circuit must be emptied and replaced with nitrogen.
Keep in mind that there may be some refrigerant fluid remaining in certain parts of the circuit after it has been emptied and replaced with nitrogen. (Creation of a flame is possible).

A2 – 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.
A3 – 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).

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) % of glycol needed

-10

-15

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.

A4 – Treatment of the water in the heating circuit
It is MANDATORY to read the additional document concerning the quality of waterusedforfillingtheinstallation.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.
A4.1 – Preparing the hydraulic circuit (rinsing)
Before installing the Pilot and the HTi 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 above mentioned waste from getting into the HTi70 Heat Pump heat exchanger, or from obstructing the filter installed on the incoming water inlet.
A4.2 – 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.
A4.3 – 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. Furthermore, 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 FOR THE 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.
– Thoroughly rinse the installation until the water runs clear, with no traces of impurities left.

– MANUAL HTi70 11 14 kW HEAT PUMPS –

– 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 or SENTINEL X800. – Thoroughly 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.
A5 – Dimensions

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 e cient resistance to corrosion. To find this information refer to their user manual.
