Panasonic Aquarea heat pump
Overview of System
The centre of your system is the market leading high performance
“Panasonic Aquarea” air source heat pump. This heat pump can
provide all your heating and hot water, heating will be delivered using
underfloor, traditional radiators or fan assisted radiators, Hot water
will be supplied from a cylinder, Delivery of heat is usually controlled
by the Panasonic controller, which will automatically operate your
heat pump when heating is required during the heating season and
hot water all year round. Room heating control will be from room
wall mounted thermostats or on the radiators (TRV’s).

AQUAREA USER GUIDE

The Panasonic Aquarea System Main Components
Outdoor Unit
The outdoor unit extracts temperature from the air when the fan is turning to start the process of changing this low temperature
to a high temperature using a compression cycle, once the compression cycle is carried out the heat is transferred to the heating
or hot water depending on requirements.
Radiators
To optimise the maximum efficiency and lowest flow rate from the heat pump to heat the room,
radiators can be wider or deeper than radiators you expect to see when connected to a boiler system.
For maximum efficiency and individual room temperature control, Thermostatic Radiator Valves
(TRV’s) are fitted.
Most radiator thermostats will either have numbers or Roman numerals marked on them when they
are adjusted, the higher the number, the warmer the room target set will be.
Underfloor Heating (UFH)
Where underfloor heating is installed you will see a manifold in a cupboard with pipes coming off
them and going into the floor, these pipes heat the floor and therefore the room, the room
temperature will be controlled by a room thermostat connected.
Do not use a high insulated product in floor finishing as this will inhibit the heat being transferred
from floor to air, and in turn increase the flow temperature to achieve target air temperature, with
increased running costs.
Fan Coil (fan Assisted Radiators)
Designed to operate at a lower flow temperatures than traditional radiators to heat the room and
ideal to be used with heat pumps where underfloor is not an option. These smart fan coils also have a
reduced footprint so take up less space than traditional radiators.
Monobloc
Panasonic supply 2 types of heat pumps, firstly a Monobloc system, in this system the hot water
produced to feed the heating and hot water is produced externally from the property inside the
outdoor unit.
Bi-Bloc
The other Panasonic unit is called a Bi-Bloc system this unit generates hot water from an internal
unit (Hydro module) connected to an outdoor unit.
All in one*
New All in One hydromodule + 200L tank
Panasonic has developed a highly efficient solution, easy to install.
Based on the Bi-Bloc system, you have an outdoor unit, with the Hydro Module and DHW Cylinder all
in one cabinet indoors.
Cylinder
Where a system is installed to supply hot water there will be a cylinder with ready to use stored hot
water at approximately 50°C, this water is lower than you would expect from a boiler system but
hotter than you require for washing/showering 39-44°C, more volume is stored to compensate for
less cold water mixing for use, therefore saving money on not heating water to a higher stored
temperature.
Room Thermostat (Optional)
This allows a simple adjustment to the room temperature, the higher the room target set the higher
the running cost. It can be supplied as an option by Panasonic (PAW-A2W-RTWIRED or
PAW-A2W-RTWIRELESS) or another one can be used.

Cleaning and Maintenance Instructions
RECOMMENDATIONS
Cleaning Instructions
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.
Indoor Unit
• Do not splash with water directly.
• Wipe the unit gently with a soft dry cloth.
Water Filter
• Clean the water 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.
For extended non-use
• The water inside the Domestic Hot Water Tank should be
drained.
• Disconnect the power supply.
Non serviceable criteria
Switch off power supply then please consult an authorised
dealer under the following conditions:
• Abnormal noise during operation.
• Water/foreign particles have entered the Remote
Controller.
• Water leaks from the indoor unit.
• Circuit breaker switches off frequently.
• Power cord becomes excessively warm.
Maintenance
User
In order to ensure optimal performance of the units, user may inspect and clear any obstruction on the air inlet and outlet
vents of the outdoor unit.
Installer/Engineer
• In order to ensure safety and optimal performance of the units, seasonal inspections on the units, functional check of
RCCB/ELCB, field wiring and piping have to be carried out at regular intervals by authorised installer/engineer
• Specific to the Domestic Hot Water Tank, it is important to service the Water Filter Set periodically and inspect the Anode
Bar annually. The Anode Bar* which protects the tank body will corrode, depending on water quality. When diameter is
approximate 8mm, the Anode Bar must be replaced.
• Users should not try to service or replace parts of the unit.
• Contact authorised dealer for scheduled inspection.
*Anode Bar is fitted to only certain cylinders in Ireland, NOT used in the UK.
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.

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 pre-set 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.
Loud refrigerant noise continues for several minutes. It is caused by protection control during device operation at
outdoor ambient temperature lower than -10°C.
*1 COOL mode is unavailable System has locked to operate in HEAT mode only.
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
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
Remote Controller
Power supply is working correctly, or a power failure has occurred.
*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 (This means when COOL mode is available).
