You also need to check that the pH value of the fill and top-up water is in accordance with VDI 2035. As major engine compo-
nents in contact with water are made of aluminium, a pH value of 8.2 to 8.5 is ideal.
Before installing your XRGI system, you must consult your gas supply company and district master chimney sweep, and obtain
your electricity supplier's consent.
The system must only be installed by an authorised and trained EC POWER specialist, who will be responsible for proper
installation and commissioning.
When deciding where to install the system, follow local rules for furnace rooms, your energy supplier's instructions and TRGI.
The installation area must be fitted with the air vents specified by TRGI rules. It should also be frost-free. If you are using pro-
pane gas as fuel, observe TRF 2008 requirements.
The Power Unit must not be set up in the immediate vicinity of air inlets (freezing risk when turned off). The minimum footprint
required to set up a Power Unit is approx. 4 m². It must be accessible from all sides for the required maintenance work to be
performed. The maintenance clearances shown below should be observed:
The room temperature should not exceed 35 °C. Transient temperatures may reach 40 °C, but this will shorten the service life
of some components (electronic modules). The room must be fitted with mechanical extractors and temperature controlled if
necessary.
The room should be dust-free to avoid reducing the service life of the air filter.
