10.1 General
Grant Aerona³ Heat Pumps require only the minimum of routine
servicing and maintenance.
This should be carried out on an annual basis and consist of the
following:
Heat pump - check:
•
Visual condition of the heat pump
•
Any debris/obstructions for the evaporator fins – remove if
found
•
Remove by comb or foam based cleaner - do not attempt
to do this manually
•
The fan outlet is not obstructed - remove if found
•
Condensate drain opening is clear
•
Flexible hose condition
•
Pipe insulation condition
•
Remote controller settings
•
That no refrigerant is leaking
•
All electrical connections and PCB for scorching or dry cables
•
If the Aerona³ heat pump is installed within 15 miles of the
coast, the evaporator must be sprayed with AFC50 and this
repeated on each annual service.
Heating system - check:
•
Expansion vessel pressure
•
Operation of pressure relief valve
•
Heating system pressure – top up if necessary
•
Correct concentration of corrosion/antifreeze protection
•
Heating and hot water controls settings
•
Any leaks on system
•
For any sign of leakage from the refrigerant circuit - refer to
Section 10.6.
•
Magnetic filter is cleaned
master reset (resetting all parameters to their defaults)
All parameters can be reset to their original defaults. The procedure
is as follows:
1. Press the Menu
l
and the – and +
o
buttons on the remote
controller simultaneously for three seconds to enter the
installer level.
2.
Press and hold the low tariff/night mode (key lock)
m
button for
ten seconds. All parameters will now be reset.
3. To return to normal operation, press and hold the Menu
l
and
the – and +
o
buttons simultaneously for three seconds, or
simply leave the remote controller for ten minutes.

servicing
10.2 Air Inlet and outlet
The air inlet grille and evaporator must be checked and leaves or
any other debris removed from the space between the grille and the
evaporator fins.
take care not to damage or distort the Aluminium fins of the
evaporator when removing any debris.
! CaUtiOn !
Ensure that both the air inlet to the evaporator and the discharge
from the fan outlet are unobstructed. Any foliage, plants, etc. near
the heat pump must not be allowed to grow over the heat pump.
Under no circumstances should anything be stacked on or against
the heat pump.
Refer to Section 3.5.2 for the required clearances around the heat
pump.
10.3 condensate Disposal
Check that the condensate drain hole in the bottom of the heat
pump is not blocked.
10.4 Heating system connections
Check the condition of the flexible hoses. Replace if damaged or
leaking.
10.5 Heat Pump controls
Check that settings on the remote controller are as set when
commissioned. Refer to settings given in the relevant sections of
these instructions. Reset to commissioned settings if necessary.
10.6 refrigerant
Under no circumstances should the refrigerant be vented from the
charging points on the refrigerant circuit of the heat pump.
If any work is required to be carried out on the refrigerant circuit, it
MUST be undertaken by an F-gas registered refrigeration engineer
On no account should any such work be carried out by unqualified
personnel.
