5.1 Filling the System With Water
5.2 Converting For Use With a Different Type of
Gas
After all system connections are performed with care, perform
the following steps:
•
Connect the appliance to the main power supply. Due to
low pressure, error code “Err HJ-09” will appear on the
user interface and The Daikin Eye light will be red.
•
Open all radiator valves.
•
Set all isolating valves to vertical (open ) position.
•
Measure system water height
•
Slowly turn the filling valve until pressure reaches a value
around 0.8 bar for system heights up to 6 metres. For
longer system heights, refer to below table to determine
filling pressure. Filling operation should be done slowly.
When pressure exceeds 0.8 bar, the error code will dis -
appear and Daikin Eye light will turn to blue. Turn off the
filling valve.
•
System pressure value can be monitored from the user
interface.
•
Make sure the automatic air vent valves located on the
pump and heat exchanger are opened. Vent the air from
the installation with the manual air vent screws on the
radiators. Make sure screws are tightened after venting.
•
If after the purge the pressure decreases below 0.8 bar,
refill the system with water until the pressure reaches 0.8
bar again.
•
Check the central heating circuit - especially the cou -
plings of the circuit - for leakage.
•
Isolate the boiler from power mains.
To convert the system to be used with a different type of gas:
Open the front cover of the appliance as described in this
manual.
To set natural gas, adjust screw on the gas valve to “1” posi -
tion (1)
To set LPG, adjust the screw to “2” position .
Mount the front cover, connect the appliance to the main pow -
er supply.
