1.1 General
The Grant Aerona³ range consists of three compact, lightweight, MCS
approved, monobloc, air-to-water, inverter driven, single-phase air
source heat pumps working with R410A refrigerant.
It is important that these installation and servicing instructions are
followed to ensure correct installation and operation. Failure to do so
may result in poor performance.
It is not within the scope of this manual to design the heating system
or provide any advice regarding the layout of the system or any of the
controls required for any individual heating system.
These instructions do not replace the installation or users manuals
for any additional components used in the design of your system e.g.
cylinders, motorised valves, programmers, solar thermal devices,
buffers, etc.
These instructions must be left with the product for future
reference.
1.2 Outputs
There are three models in the Aerona³ range as follows:
• HPID6 - 6kW*
• HPID10 - 10kW*
• HPID16 - 16kW*
* at 7°C air and 35°C flow temperature
1.3 Main Components
Each model incorporates the following main components:
• DC inverter - this responds rapidly to changing conditions
to provide the necessary output to meet heating demands
by varying the speed and output of the compressor, fan
and circulating pump. This reduces the on/off times of the
compressor, keeping the water temperature constant during
operation reducing the electricity consumption.
• Compressor - a high-efficiency DC twin-rotary compressor to
provide smooth performance and quiet operation.
• Plate heat exchanger (condenser) - the high-efficiency plate
heat exchanger is used to transfer heat to the heating system
primary circuit.
• Fan - a high-efficiency DC fan motor is used for smooth and
quiet operation. A single fan is fitted to the 6kW (5 blade) and
10kW (3 blade) units. Two fans (3 blade) are fitted to the 16kW
unit.
• Circulating pump - high-efficiency DC pump speed controlled
from the ASHP control PCB.
• Base tray heater - factory fitted electric heater prevents
condensate in the base of the heat pump from freezing. When
the ambient temperature reaches 2.5°C, the base tray heater
turns on and at 5.5°C turns off (ΔT of 3k). This cannot be
adjusted or turned off.
• Pressure relief valve - a 3 bar pressure relief valve is factory
fitted.
• Air purge valve (automatic air vent) - factory fitted to assist
in the removal of air from the heating primary circuit of the heat
pump.
1.4 Planning Permission
The installation of a Grant Aerona³ heat pump on domestic premises
may be considered to be permitted development, not needing an
application for planning permission, provided ALL the limits and
conditions listed on the Planning Portal website are met.

1 Introduction
1.5 DNO Application
An application must be made to the Distribution Network Operator
(DNO) before connecting the heat pump(s) to the mains electrical
supply. There are six DNOs operating the electrical distribution
network throughout England, Scotland and Wales and the application
must be made to the DNO covering the area concerned.
The necessary information required to make this application (J-forms)
can be downloaded from the Grant UK website (www.grantuk.com),
completed and then submitted to the correct DNO for the area in
question.
1.6 Servicing
It is recommended (and a requirement of the product guarantee) that
the heat pump should be regularly serviced, at least once a year and
the details entered in the Service Log by the service engineer.
1.7 Important Advice
1. It is essential that the full layout of the system is understood
before the installation of any component is undertaken. If you
are in any doubt, please stop and seek advice from a qualified
heating engineer or from Grant UK. Please note that Grant UK
will not be able to offer specific advice about your system unless
we designed it. In this case, we will always refer you to seek the
advice of a qualified system designer.
2. The heat pump must be installed and commissioned in
accordance with these installation and servicing instructions.
Deviations of any kind will invalidate the guarantee and may
cause an unsafe situation to occur. Please seek advice from
Grant UK if any of these user, installation and servicing
instructions cannot be followed for whatever reason.
3. The heat pump contains high pressures and high temperatures
during normal working conditions. Care must be taken when
accessing the internal workings of the heat pump.
4. The heat pump contains an electrically driven fan which rotates at
high speed. Disconnect the heat pump from the electrical supply
before removing the top cover.
