FC 300 Instruction Manual
General Specifications
Copper (140/167°F, 60/75°C) conductors recommended.
Aluminum conductors
Aluminum conductors are not recommended. 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.
