Before use, make sure the system has been installed correctly by an authorised dealer according to the given instructions. • Panasonic Air-to-Water is a split system, consisting of two units: indoor and outdoor units. The indoor unit consist of the hydromodule and 200L sanitary water tank. • These operating instructions describe how to operate the system using the indoor and outdoor units.
Safety precautions To prevent personal injury, injury to others or property damage, please comply with the following: Incorrect operation due to failure to follow instructions below may cause harm or damage, the seriousness of which is classified as below: WARNING This sign warns of death or serious injury. CAUTION This sign warns of injury or damage to property. The instructions to be followed are classified by the following symbols: This symbol denotes an action that is PROHIBITED.
Do not insert your fingers or other objects into the Air to water indoor or outdoor unit, rotating parts may cause injury. It is strongly recommended that Install Residual Current Device (RCD) on-site to prevent electric shock and/ or fire. Do not touch the outdoor unit during lightning, it may cause electric shock. Before obtaining access to terminals, all supply circuits must be disconnected. Do not sit or step on the unit, you may fall down accidentally. Do not install the indoor unit outdoors.
Safety precautions CAUTION Indoor unit and outdoor unit Do not wet the Remote Controller. Failure to do so may result in electric shock and/or fire. Do not wash the indoor unit with water, benzine, thinner or scouring powder to avoid damage or corrosion at the unit. Do not press the buttons on the Remote Controller using hard and sharp objects. Failure to do so may cause damage to the unit. Do not install the unit close to any combustibles or at bathroom.
WARNING This appliance is filled with R32 (mild flammable refrigerant). If the refrigerant is leaked and exposed to an external ignition source, there is a risk of fire. Indoor unit and outdoor unit The appliance shall be installed, and/ or operated in a room with floor area larger than Amin (m²) and keep away from ignition sources, such as heat/ sparks/open flame or hazardous areas such as gas appliances, gas cooking, reticulated gas supply systems or electric cooking appliances, etc.
Safety precautions • Any part of refrigerating circuit (evaporators, air coolers, AHU, condensers or liquid receivers) or piping should not be located in the proximity of heat sources, open flames, operating gas appliance or an operating electric heater. • The user/owner or their authorised representative shall regularly check the alarms, mechanical ventilation and detectors, at least once a year, where as required by national regulations, to ensure their correct functioning.
1. Installation (Space) • Product with flammable refrigerants, shall be installed according to the minimum room area, Amin (m²) mentioned in Installation Instructions. • In case of field charge, the effect on refrigerant charge caused by the different pipe length has to be quantified, measured and labelled. • Must ensure the installation of pipework shall be kept to a minimum. Avoid use dented pipe and do not allow acute bending. • Must ensure that pipe-work shall be protected from physical damage.
Safety precautions 2-2. Work • Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the precautions in #2-2 to #2-8 must be followed before conducting work on the system. • Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapour being present while the work is being performed.
2-5. No ignition sources • No person carrying out work in relation to a refrigerating system which involves exposing any pipe work 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. They must not be smoking when carrying out such work.
Safety precautions 2-8. Checks to electrical devices • Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. • Initial safety checks shall include but not limit to:-That capacitors are discharged: this shall be done in a safe manner to avoid 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.
4. 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 current permitted for the equipment in use. • Intrinsically safe components are the only types that can be worked on while live 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.
Safety precautions 8. 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 with inert gas -> open the circuit by cutting or brazing.
10. Decommissioning • Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details. • 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 recovered refrigerant. • It is essential that electrical power is available before the task is commenced.
Safety precautions 12. Recovery • When removing refrigerant 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 are available.
