Critical Components Information
Components having special characteristics are marked
and must be replaced with parts having specifications equal
to those originally installed.
Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
Meter impedance should be equivalent to 1500 ohm shunted
Leakage current must not exceed 0.5mA.
WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/
electronic and/or plastic (where applicable) components may also contain traces of chemicals
found by the California Health and Welfare Agency (and possibly other entities) to cause
