USER MANUAL WHUH09FE5 PANASONIC

• 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.

• These operating instructions describe how to operate the system using the indoor and outdoor units.

• As for the operation of other products such as water tank, radiator, external thermo controller, and underfloor units, refer to the operating instructions of each product.

• Some functions described in this manual may not be applicable to your system.

• Consult your nearest authorised dealer for further information. The illustrations in this manual are for explanation purposes only and may differ from the actual unit. They are subject to change without notice for future improvement. Operating conditions HEATING Water outlet temperature (°C) (Min. / Max.) 25 / 65 Outdoor ambient temperature (°C) (Min. / Max.) -20 / 35 When the outdoor temperature is out of the range in the table, the heating capacity will drop significantly and the outdoor unit may stop operating for its protection. The unit will restart automatically after the outdoor temperature returns to the specified range.

How to use12 Indoor unit• Do not splash water directly.Wipe the unit gently with a soft dry cloth.To ensure optimal performance of the system, cleaning has to be carried out at regular intervals.Consult an authorised dealer.• Disconnect the power supply before cleaning.• Do not use benzine, thinner or scouring powder.• Use only soap ( pH7) or neutral household detergent.• Do not use water hotter than 40 °C.External filter• Clean the external filter at least once a year. Failure to do so may cause the filter to clog up, which may lead to system breakdown. Consult an authorised dealer.Outdoor unit• Do not obstruct the air inlet and outlet vents. Failure to do so may result in low performance or system breakdown. Remove any obstruction to assure the ventilation.• When it snows, clean and remove snow around the outdoor unit to prevent the air inlet and outlet vents from being covered with snow. Inspection
• In order to ensure optimal performance of the units, seasonal inspections on the units, external filter and field wiring have to be carried out at regular intervals. Consult an authorised dealer about maintenance.• Clear any obstruction on the air inlet and outlet vents of the outdoor unit. For extended non-use
• Disconnect the power supply. Non serviceable criteria Disconnect the power supply then please consult an authorised dealer under the following conditions:• Abnormal noise during operation.• Water/foreign particles have entered the control panel.• Water leaks from the indoor unit.• Circuit breaker switches off frequently.• Power cord becomes unnaturally warm. Cleaning instructions Weekly timer setting ■ Note:
• You may set the timer for each day of the week (Monday to Sunday) with 6 programmes per day.• When the system is switched on by the timer, it will use the previously set temperature to control the water outlet temperature.• The same timer programme cannot be set on the same day.• You may also select 2 or more days with the same timer setting. How to use Water pressure gauge• Do not press or hit the glass cover using hard and sharp objects. Failure to do so may cause damage to the unit.• Ensure that the water pressure is between 0.05 and 0.3 MPa (0.1 MPa = 1 bar).• In case the water pressure is out of the above range, consult an authorised dealer.13 English The following symptoms do not indicate malfunction. Symptom Cause Water flowing sound during operation. • Refrigerant flow inside the unit. Operation is delayed a few minutes after restarting.

• The delay is a protection for the compressor. Outdoor unit emits water/steam. • Condensation or evaporation occurring in the pipes. Steam comes out of the outdoor unit in the heating mode.

• It is caused by defrost operation in the heat exchanger. Outdoor unit does not operate. • It is caused by the protection control of the system when outdoor temperature is out of the operating range. System operation switches off. • It is caused by the protection control of the system. When the water inlet temperature is lower than 10 °C, the compressor stops and the backup heater power turns on. System is hard to heat up. • When the panel and the floor are heated simultaneously, warm water temperature may decrease, which may reduce the heating ability of the system.

• When the outdoor air temperature is low, the system may need longer time to heat up.

• Discharge outlet or intake inlet in the outdoor unit is blocked by some obstacle, such as a pile of snow.

• When the preset water outlet temperature is low, the system may need longer time to heat up. System does not heat up instantly. • System will take some time to heat up the water if it starts to operate at cold water temperature. Backup heater is automatically turned ON when it is disabled.

• It is caused by the protection control of the indoor unit heat exchanger. Operation starts automatically when the timer is not set.

• Sterilisation timer has been set. Display power consumption remains as previous value.

• Memory is saved on hourly basis. If a power failure occurs, the data kept from last hour will be displayed.

• Total power consumption has reached 999 days. press to reset the counter. HEAT indicator blinks on the display. • System is performing deice operation. Loud refrigerant noise continue for a few minutes.

• It is caused by protection control during deice operation at outdoor ambient temperature lower than -10 °C. Check the following before calling for servicing. Symptom Check Operation in HEAT mode is not working efficiently.

• Set the temperature correctly.

• Close the panel heater valve.

• Clear any obstruction in the air inlet and air outlet vents of the outdoor unit. Noisy during operation. • Outdoor unit or indoor unit has been installed at an incline.

• Close the cover properly. System does not work. • Circuit breaker has tripped/activated. Operation LED is not lit or nothing is displayed on the control panel.

• Check that the power supply is working correctly, or that a power failure has not occurred. Troubleshooting Force Heater Mode Button

• If a malfunction occurs in the system, the backup heater may be used to heat up the water. Press to switch on the backup heater.

• Press to switch off the backup heater.

• In the Force Heater mode, no other operation can be used. How to use / Cleaning instructions / Troubleshooting14 The operation LED blinks and error code appears on the display.
