IMPORTanT:
TURN ON THE ELECTRICAL POWER SUPPLY TO THE BOILER. MAKE SURE THAT THE PROGRAMMER IS NOT CALLING FOR HEAT
AT THIS STAGE!
FIll InG ThE hOT WaTER CIRCuT. (If applicable)
1. Check the pressure in the potable vessel is set to 3 Bar.
2. Check that all plumbing connections are tight.
3. Open the furthest away tap outlet.
note: Make sure that the filling loop is closed at this stage!
5. Turn on the mains water supply to the unit.
6. It will take a few minutes to fill the cylinder, once the water comes through the tap outlet let it run.
7. Open the other hot water outlets and purge all air out of the system.
8. Once fully purged close all the outlets and further check for leaks.
FIllInG ThE PRIMaRY hEaTInG CIRCuT.
THE PRIMARY CIRCUT MUST BE FLUSHED IN ACCORDANCE TO BS 7593
1. Connect the primary filling loop and tighten.
2. Make sure that all primary connections are tight before filling.
3. Open the filling loop and allow the system to start filling.
4. Press the right arrow key on the boiler control panel until the A (bar) led is illuminated.
5. fill the system to 2 bar, then start to purge the radiators until all the air is out the system.
6. This will have to be repeated several times to fully purge the system re-filling as you go.
system protection:
Failure to protect the system will invalidate the manufacturer’s warranty.
1. Fill the system with cold mains water to the recommended pressure 1.5 bar and check for leaks, then drain the system thoroughly
making sure all drain cocks are fully open and that the system is completely drained.
2. Add Fernox F3 cleaner to the system at the furthest point from the boiler, this is to allow the substance to fully dilute throughout the
system. If you are unsure of the correct dose rate, contact Fernox on 03301007750 for advice.
3. Re-fill the system and circulate the F3 cleaner prior to the boiler being fired up. Commission the system in the normal way. The
cleansing agent must be in the system for a minimum 1 hour with the system running at normal operating temperature. A longer
period of time would be more beneficial to the cleansing process especially if excess flux was used or is an old system. F3 cleaner
can be left in the system for up to a maximum of one week running on a normal heating cycle. (We recommend that existing systems
are power flushed as per BS 7593 and PAS33 regulations)
4. Drain and flush the system thoroughly to remove the cleaning agent and any debris or contaminants. This is a critical part of the
cleaning process and must be carried out correctly. Use a rinse test meter (TDS), such as the Fernox CTM. The reading must be within
10% of the mains ppm value.
5. After the system has been thoroughly flushed and TDS readings are within 10% you can now add Fernox F1. This will protect against
the formation of scale, corrosion and microbiological growths. It is crucial however, that for the protector to work correctly, the
system must be properly cleansed and flushed.
6. Now attach the label included within the Fernox F1 packaging completed and attached adjacent to the boiler.
We recommend inhibitor levels are checked on an annual basis (usually during the service) or sooner if the system content is lost.
This should be carried out using a Fernox inhibitor Test Kit. Fernox Technical Service Help line on 0870 870 0362 for further assistance.
