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: This appliances is not intended for accessibility by the general public. WARNING This sign warns of death or serious injury. CAUTION This sign warns of injury or damage to property.
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.
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.
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.
Safety precautions 2. Servicing 2-1. Service personnel • The system is inspected, regularly supervised and maintained by a trained and certified service personnel who is employed by the person user or party responsible. • Ensure the actual refrigerant charge is in accordance with the room size within which the refrigerant containing parts are installed. • Ensure refrigerant charge not to leak.
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.
Safety precautions 2-6. 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. 2-7.
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.
6. Detection of flammable refrigerants • Under no circumstances shall potential sources of ignition be used in the searching or detection of refrigerant leaks. • A halide torch (or any other detector using a naked flame) shall not be used. Safety precautions 5. Cabling • Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects.
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.
11. Labelling • Equipment shall be labelled stating that it has been de-commissioned 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. Safety precautions h) Do not over fill cylinders. (No more than 80 % volume liquid charge). i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
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.
