SilentMaster Warranty
M.D. Manufacturing, Inc. warrants its Silent Master power units against electrical component failure for a period of twelve (12) years. This warranty is transferable with the unit and is not solely limited to the original owner. Any parts (excluding filters) required within the first twelve years will be furnished free of charge by the Authorized Dealer from whom the power unit was originally purchased. In addition, all Silent Master units are guaranteed for life against defects in materials and workmanship.
If an Authorized Dealer is not nearby, M.D. Manufacturing, Inc. will honor and perform required warranty services. The end user must return the unit to the factory freight pre-paid. This warranty does not apply to applications outside of North America, commercial applications, misuse, abuse, acts of God, operating without the filters, or units tampered with by unauthorized personnel.
Exterior Venting
Venting not required but optional. When venting, vent both exhaust ports.
