   iii. General Work Area
   All maintenance staff and others working in the local area shall be instructed on the nature of the work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
   iv. Checking for the presence of refrigerant
   The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. nonsparking, adequately sealed or intrinsically safe.
   v. Presence of fire extinguisher
   If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
   vi. No ignition sources
   No person carrying out work in relation to a refrigeration system that involves exposing any pipework that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removal, and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.
   vii. Ventilated area
   Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
   viii. Checks to the refrigeration equipment
   Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flammable refrigerants:
   –The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
   –The ventilation machinery and outlets are operating adequately and are not obstructed;
   –If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
   –Marking of the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
   –Refrigeration pipes or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant- containing components unless the components are constructed of materials that are inherently resistant to being corroded or are suitably protected against being so corroded.
   ix. Checks to electrical devices
   Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised.
   Initial safety checks shall include:
   • That capacitor is discharged: this shall be done in a safe manner to avoid the possibility of sparking;
   • That there no live electrical components and wiring are exposed while charging, recovering, or purging the system;
   • That there is continuity of earth bonding.

7. Repairs sealed components:
   a) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
   b) Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, an excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc. Ensure that apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
   NOTE: The use of silicone sealant may inhibit the effectiveness of some types of the leak.

8. Repair to intrinsically safe components
   Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and currently permitted for the equipment in use.
   Intrinsically safe components are the only types that can be worked on whillivingve in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

9. Cabling
   Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

10. Detection of flammable refrigerants
    Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.

11. Leak detection methods
    The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
    Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed.
    Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.

12. Removal and evacuation
    When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to:
    • Remove refrigerant;
    • Purge the circuit with inert gas;
    • Evacuate;
    • Purge again with inert gas;
    • Open the circuit by cutting or brazing.
    The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times.
    Compressed air or oxygen shall not be used for this task.
    Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to the atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place.
    Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.

13. Charging procedures
    In addition to conventional charging procedures, the following requirements shall be followed.
    –Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.
    –Cylinders shall be kept upright.
    –Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
    –Label the system when charging is complete (if not already).
    –Extreme care shall be taken not to overfill the refrigeration system.
    –Prior to recharging the system, it shall be pressure tested with OFN. The system shall be leak tested on completion of charging prior to commissioning. A follow-up leak test shall be carried out prior to leaving the site.

14. Decommissioning
    Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.
    a) Become familiar with the equipment and its operation.
    b) Isolate system electrically.
    c) Before attempting the procedure ensure that:
    • Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
    • All personal protective equipment is available and being used correctly;
    • The recovery process is supervised at all times by a competent person;
    • Recovery equipment and cylinders conform to the appropriate standards.
    d) Pump down refrigerant system, if possible.
    e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
    f) Make sure that cylinder is situated on the scales before recovery takes place.
    g) Start the recovery machine and operate in accordance with manufacturer’s instructions.
    h) Do not overfill cylinders. (No more than 80 % volume liquid charge).
    i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
    j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from the site promptly and all isolation valves on the equipment are closed off.
    k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

15. Labelling
    Equipment shall be labeled stating that it has been decommissioned and emptied of refrigerant.
    The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.

16. Recovery
    When removing refrigerants from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labeled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with a pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leakfree disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained, and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consulting manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Commissioning and Maintenance

1. Precautions Before Commissioning
   1.1 Is the machine adequately installed?
   1.2 Is the wiring and pipe correct?
   1.3 Whether the water pipelines are empty or not?
   1.4 Whether the heat insulation has been perfected?
   1.5 Is the ground wire connected reliably?
   1.6 Whether the power supply voltage matches the rated voltage of the machine?
   1.7 Is there any obstacle in the air inlet and outlet of the machine?
   1.8 Is the safety valve installed correctly?
   1.9 Whether the leakage protector can operate effectively?
   1.10 The system water pressure is not less than 0.15 MPa, and the maximum pressure cannot exceed 0.5 MPa;
   1.11 In winter, the machine needs to be energized at least 24 hours before the operation, as the compressor needs to be preheated.

2. Commissioning
   Use the controller to control the machine and check the following items according to the instruction manual: (If there is any fault, please find out the faults and reasons described in the manual and eliminate them)
   2.1 Is the controller regular?
   2.2 Is the function key of the controller regular?
   2.3 Is the drainage normal?
   2.4 Test whether the heating mode and cooling mode are working correctly;
   2.5 Is the outlet water temperature average?
   2.6 Whether there is vibration and abnormal sound during operation?
   2.7 Does the generated wind, noise, and condensate affect neighbours?
   2.8 Is there a refrigerant leakage?

3. Operation and Debugging
   3.1 About 3mins of protection
   Due to the self-protection of the compressor, the machine cannot be restarted again within 3 mins.
   3.2 Feature of heating operation
   If the ambient temperature is too high during operation, the outdoor motor may run low or stop.
   3.3 In the case of heating operation, when the unit has frost formation, the defrosting procedure (about 2-8 minutes) is automatically performed to improve the heating effect. The outdoor motor stops running during the “defrost” operation.
   3.4 Power Outage
   If there is a power outage during operation, the machine will stop running. Before the power outage, the controller automatically memories the ON/OFF status of the device. After repowering, the controller will send an ON/OFF signal to the device according to the state of memory before the power outage to ensure that the device recovers from the previous status from abnormal power failure.
   3.5 Heating Capacity
   Because the heat pump absorbs heat from the outside, the heating capacity will be reduced once the outdoor temperature is lowered.
   3.6 Electric Leakage Protector
   After the unit has been running for some time (usually one month), the leakage protector needs to press the test button under the closed energized state to check whether the performance of the leakage protector is regular and reliable (the leakage protector should be disconnected once every time the test button is pressed). If the accident is not found, the test can be sent once. If it is not working, the cause should be found, and if necessary, the action characteristic test should be carried out. After checking, it is confirmed that the leakage protector itself has failed. It should be replaced or repaired in time.
   3.7 Working Temperature Range
   To use the machine correctly, please operate under the following conditions, outdoor temperature: – 30ºC ~ 45ºC for heating mode, 16ºC ~ 45ºC for cooling mode.
   3.8 Antifreeze in the winter
   When the ambient temperature is below 0ºC, it is strictly forbidden to cut off the power. If there is an unexpected power failure under this condition, please drain the water from the heat.

4. Maintenance
   1. Please check whether the grounding wire is connected reliably before use. If there is any abnormality, please replace it in time.
   2. Please check the air inlet and outlet of the outdoor unit regularly for blockage.
   3. Professionals must clean the outdoor unit heat exchanger, casing, and water circulation piping. It is recommended to clean the filter of the waterside filter regularly (cleaning is usually done once a year, depending on the actual situation).
   4. Regularly check that the safety valve is working correctly, and ensure that the drain can be drained normally by manually turning the red knob (usually once every three months, depending on the actual situation).
   5. Regularly (usually once a year, but depending on the actual situation) check whether the water pipe joint and the refrigerant connection pipe are leaking or leaking refrigerant (there are oil leakage marks). If there is any leak, please contact the seller.
   6. The machine can only be serviced by a professional. The device must be cut off before contacting the wiring part.
   7. Once the machine will not be used for a long time, please cut off the power, drain the water in the pipeline, and close each valve.

Fault Protection Instructions

1. The machine stops running when a fault is detected;
2. When the fault is removed, the compressor is shut down for three minutes before the machine can be put back into operation;
3. If there are three consecutive low-pressure faults, high-pressure fault, over the current spot, and gas exhaust temperature too high within 30 minutes, the machine will immediately stop running. After the fault is rectified, turn the power on again, start the controller, and the device can be put into operation.
4. If the machine stops running due to the inlet water temperature sensor or the coil temperature sensor fault due to compressor protection, the device will have to be back into operation 3mins later after the spot is removed. If the ambient temperature sensor fails, the machine continues to run.

Maintenance Instructions

1. The machine is equipped with an inspection needle valve on the suction and exhaust pipes. The maintenance personnel can connect the pressure gauge to check the high and low-pressure conditions of the system.

2. If the machine is filled with refrigerant under operating conditions, the refrigerant must be served at the needle valve of the low-pressure side. Suppose the refrigerant is added to the suction side.
   In that case, the refrigerant opening must be small so that the refrigerant in the refrigerant bottle slowly enters the system to prevent liquid slamming.

3. Refrigerant leakage detection
   Check if there is any leakage at the joints with soapy water or a refrigerant leak detector. When a refrigerant leak occurs, the leak point must be found, and the leak point must be repaired. Please ensure no refrigerant or other pressures are left in the system when improving the leak point. Otherwise, it will easily cause copper pipe explosive during welding. The tube is blasted by refrigerant pressure or additional pressure, causing accidental injury to the operator.
   Note: When refrigerant leakage occurs in a small space, open all vents or forced ventilation to discharge the refrigerant before performing related operations to prevent people from suffocating accidents.

Control introduction

Water quality requirements on the circuit
Water quality must meet the standards of European Directive 98/83 EC and the criteria set out in UNE 112.076. Water quality should be analysed before use; to evaluate criteria such as concentration, pH value, conductivity, chloride ion concentration (Cl-), sulfide ion concentration (S2-), etc. Some of the parameters on the chemical ingredients are indicated in the following table:

• PH value: between 6.5 and 8.5
• Water hardness: <50ppm.

Before connecting the outdoor unit:
In any installation, both new and existing, a thorough cleaning of the pipes must be carried out using a suitable chemical cleaning product,and then wash the pipes to clean said chemical agent. To avoid damage to the pipes, you must add anionic, cationic  corrosion inhibitors, a mixture of both or film products that block the existing microlays, avoiding corrosion reactions and oxygen detachment. When using inhibitors or other cleaning chemicals, always read the manufacturer’s instructions and their compatibility with the materials that make up the installation.
Antifreeze
In case the installation is to operate in refrigeration mode, it is mandatory to use antifreezing.
In installations that do not operate in refrigeration mode, antifreeze must be used when there is a risk of freezing during a period of non-operation or due to environmental conditions. Antifreeze solutions must use propylene glycol with a Class 1 toxicity index. Ethylene glycol must never be used in the primary circuit.
Problems arising from poor water quality or not having treated water as described herein are not covered by the product warranty.
