System overview

Before use, make sure the system has been installed correctly by an authorised dealer according to the given instructions.

• Panasonic (Mono bloc) Air-to-Water Heatpump 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 mono bloc unit.
• 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.
• System could be locked to operate in HEAT mode and disable COOL mode.
• Some functions described in this manual may not be applicable to your system.
• Consult your nearest authorised dealer for further information.
  1 The system is locked to operate without COOL mode. It can be unlocked only by authorised installers or our authorised service partners.
  2 Only displayed when COOL mode is unlocked (Means when COOL mode is available).

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	*1 COOLING
Water outlet temperature (°C) (Min. / Max.)	25 / 55	5 / 20
Outdoor ambient temperature (°C) (Min. / Max.)	-20 / 35	16 / 43

When the outdoor temperature is out of the range in the table, the heating capacity will drop significantly and the mono bloc unit may stop operating for its protection. The unit will restart automatically after the outdoor temperature returns to the specified range.

Maintenance

Mono bloc Unit

In case of a power supply failure or pump operating failure, drain the system (as suggested in the figure below).

When water is idle inside the system, freezing up is very likely to happen which could damage the system.

• Do not obstruct the air inlet and air outlet vents, it may cause low performance or breakdown. Please remove obstacles to assure the ventilation.
• During winter, please clean and remove the snow near mono bloc unit so that the snow does not cover the air inlet and air outlet vents.

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.

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 mono bloc unit.

For extended non-use

• Do not switch off the power supply. Switching off the power supply will stop the automatic water pump operation and will cause jamming in the water pump.

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 remote control.
• Circuit breaker switches off frequently.
• Power cord becomes unnaturally warm.

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.
Mono bloc unit emits water/steam.	· Condensation or evaporation occurring in the pipes.
Steam comes out of the mono bloc unit in the heating mode.	· It is caused by defrost operation in the heat exchanger.
Mono bloc 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 mono bloc 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 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 CANCEL 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.
*1COOL mode is unavailable.	· System has locked to operate in HEAT mode only.

Check the following before calling for servicing.

Symptom	Check
Operation in HEAT/\(^{*1}\)COOL mode is not working efficiently.	• Set the temperature correctly. • Close the panel heater/ cooler valve. • Clear any obstruction in the air inlet and air outlet vents of the mono bloc unit.
Noisy during operation.	• Mono bloc 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 remote control.	• Check that the power supply is working correctly, or that a power failure has not occurred.
