2.3 Electrical wiring

Serious injury or death from electric shock may occur if wiring,
installation, disassembly or remove of wires is performed while
electrical power is energized.
Always shut off or disconnect electrical power at service panel and
lock switch or breaker and tag to prevent energizing electrical power
during work or while Flowmax 44i is not assembled and installed.
Wiring installation, disassembly and removal must be performed by
qualified persons experienced and knowledgeable about electrical
work.
