INSTRUCTIONS:
A 15 to 20 amp electrical service is recommended for proper electrical supply. Before
determining, calculate amp ratings based on the product label found on the PMB series module. Always observe
local building codes. Always use a dedicated circuit. Line load is calculated by adding the amperage of the
halogen lights to the rated amperage of the ventilator.. If the ventilator is rated in watts rather than amps, divide the
watts by 120 and this will give you the amperage rating.
CAUTION:
The neutral wire (usually white) for the ventilator must connect to the same neutral wire that
comes from the electrical panel to the liner. It is recommended to run a white neutral wire from the liner’s white
neutral wire along the same path as the red wire from the liner’s variable speed control to the ventilator.
