3.3. Electrical Installation

Aluminum Conductors
Terminals can accept aluminum conductors, but the conductor surface must be clean, and the
oxidation must be removed and sealed by neutral acid-free Vaseline grease before the conductor
is connected.
Furthermore, the terminal screw must be retightened after two days due to the softness of the
aluminum. It is crucial to keep the connection a gas-tight joint, otherwise the aluminum surface
will oxidize again.
