Before use, make sure the system has been installed correctly by an authorised dealer according to the given instructions. • Panasonic Air-to-Water Heatpump is a split system, consisting of two units: indoor and outdoor units. This system is designed to operate with Panasonic Water Tank Unit. Unless used together with the Panasonic Water Tank Unit, Panasonic does not guarantee any normal operation nor the reliability of the system.
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 wash the indoor unit with water, benzine, thinner or scouring powder to avoid damage or corrosion at the unit. Do not install the unit close to any combustibles or at bathroom. Otherwise, it may cause electric shock and/or fire. Precautions shall be taken to avoid excessive vibration or pulsation to Water piping. Protect the Water piping from accidental rupture due to moving furniture or reconstruction activities.
WARNING This appliance is filled with R290 (Extremely flammable gas, safety A3 group per ISO 817). If the refrigerant is leaked and exposed to an external ignition source, there is a risk of fire. Indoor unit and outdoor unit Protective zone is defined near the product. See section Protective zone. Be aware that refrigerant may not contain an odour, highly recommended to ensure suitable flammable refrigerant gas detectors are present, operating and able to warn of a leak.
Safety precautions • Before a new refrigerating system is put into service, the person responsible for placing the system in operation should ensure that trained and certified operating personnel are instructed on the basis of the instruction manual about the construction, supervision, operation and maintenance of the refrigerating system, as well as the safety measures to be observed, and the properties and handling of the refrigerant used.
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 refrigerant charge not to leak.
Safety precautions 2-3. Checking for 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. non sparking, adequately sealed or intrinsically safe. • In case of leakage/spillage happened, immediately ventilate area and stay upwind and away from spill/release.
2-7. Checks to the refrigerating 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 ventilation machinery and outlets are operating adequately and are not obstructed.
Safety precautions 3. Repairs to sealed components • 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.
7. The following leak detection methods are deemed acceptable for all refrigerant systems • No leaks shall be detected using detection equipment with sensitivity to detect leakage of 5g/year of refrigerant or better under a pressure of at least 0.25 times the maximum allowable pressure (>0.98 MPa, max 3.90 MPa), for example, a universal sniffer. • Electronic leak detectors may be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need recalibration.
Safety precautions • Ensure that the outlet for the vacuum pump is not close to any potential ignition sources and there is ventilation available. 9. 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.
h) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. • Electrostatic charge may accumulate and create a hazardous condition when charging or discharging the refrigerant. To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before charging/discharging. 11.
Safety precautions • 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. Consult 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.
Protective zone This outdoor unit is filled with R290 (Extremely flammable gas, safety A3 group per ISO 817). Note that this refrigerant has a higher density than air. In case of a refrigerant leak, the leaked refrigerant may accumulate near the ground. Prevent accumulation of refrigerant in any way that is potentially dangerous, explosive or risk suffocation. Prevent refrigerant from entering the building through building openings. Prevent accumulation of refrigerant in the drain grooves.

Regular Checks Indoor unit • Do not splash water directly. Wipe the unit gently with a soft dry cloth.
Cleaning instructions Maintenance FILLING THE CIRCUIT SYSTEM If the pressure is too low in the CIRCUIT system, it needs to be topped up. See the Installer Manual for more information. VENTING THE CIRCUIT SYSTEM In event of repeated filling of the CIRCUIT system, or if bubbling sounds are heard from the indoor module, the system may need venting. This is done as follows: 1. Turn off the power supply to the indoor module. 2.
Troubleshooting The following symptoms do not indicate malfunction. Symptom Cause Water flowing sound during operation. Operation is delayed a few minutes after restarting. Outdoor unit emits water/steam. Steam comes out of the outdoor unit in the heating mode. Outdoor unit does not operate. System operation switches off. System is hard to heat up. System does not heat up instantly. Backup heater is automatically turned ON when it is disabled.
