The installation must have two Class A Ground-Fault Circuit-Interrupters (GFCI). The GFCI protects against line-to-
ground shock hazard. Use a 120 V, 15 A, 60 Hz dedicated service for the blower. Use a separate 120 V, 15 A, 60 Hz
dedicated service for the bubble heater.
If the blower supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified
persons in order to avoid a hazard.
Product Notices

NOTICE: Keep the area around the blower clean and free of debris. Verify that the area around the blower is free of
sawdust, insulation, dirt, and other small loose debris. Such material can block the blower air ducts and reduce the air
flow through the blower.
