Installation and Maintenance
6.2.2 Logic Air Controller Checks
•
Access Logic Air Controller (Wall Mounted or Pre-Plumbed
version).
•
Assess if the installation conforms to the Installation
Instructions and rectify any faults.
•
Conduct Safe Electrical Isolation.
ᘐ
CAUTION: The control box may have dual electrical
supplies (a power supply from the outdoor unit and a
power supply for the DHW Cylinder immersion Heater).
Both must be isolated before removing the control box
front panel.
•
Remove Front Panel, refer to
Figure 52
and inspect
all electrical connection for signs of damage / loose
connections etc.
•
Replace Front panel and remove electrical isolation.
•
Check and record legionella settings.
•
Check and record weather compensation settings.
•
Hot Water Set Temperature.
•
Time and Date Set Correctly?
•
Fault History recorded.
•
Put the unit into DHW operation and check and record the
flow rate.
•
Put the unit into CH operation and check and record the
flow rate.
•
Confirm correct operation of the 3-way valve.
•
Confirm correct operation of secondary pumps.
•
Confirm the system warms correctly.
•
Confirm correct operation of the customer controls
including confirming settings with the customer.
•
Record consumption meter reading is fitted.
•
Record generation meter readings if fitted.
6.2.3 Logic Air Domestic Hot Water Cylinder and System Checks
6.2.4 Service Records
•
On completion of the work, fill in the Benchmark Service Record for both the Air Source Heat Pump and the DHW Cylinder.
Figure 52. Front Panel Removal
To allow for inspection,
the casing must be
removed by removing
the four screws
displayed in
Figure 52
.
•
Access Logic Air Domestic Hot Water Cylinder.
•
Isolate the cold supply to the cylinder. Remove the inlet
control valve. Inspect the gauze filter on the inlet side and
remove any debris.
•
Ensure the CH and DHW are turned off on the controller.
•
'Reduce the central heating system pressure from a
suitable drain point and check the Central Heating
Expansion vessel for pre-charge of 1 bar. Re-pressurise
as required.
•
Isolate magnetic system filter and clean magnet and mesh
filter.
•
Re-pressurise the system to 1 bar (considering the
position of the gauge in relation to the heat pump).
•
Manually check the operation of the temperature relief
valve.
•
Manually check the operation of the hot water cylinder
expansion and pressure relief.
•
Check discharge pipes from temperature and expansion
relief valves are free from obstruction and blockage and
are not passing any water.
•
Check that water pressure downstream of the pressure
reducing valve is within the manufacturer’s limits.
•
Check the pre-charge of the domestic hot water expansion
vessel (3 bar) and re-pressurise as required. This must be
done with the cold main to the cylinder isolated and a draw
off open to release any pressure.
•
Isolate the immersion heater supply.
•
Conduct safe electrical isolation at the immersion heater.
•
Check the immersion heater thermostat is turned to MAX.
•
Re-energise the immersion supply.
•
Confirm the DHW sensor is secure in its pocket.
•
Check and advise the householder not to place any
clothing or other combustible materials against or on top of
this appliance.
