force that represents the most difficult circumstance faced by a power protection product. The degree of protection a PS-PRO can offer depends on the intensity of the strike. If lightning strikes a distant power line and causes a relatively small disturbance to reach your location, the spike suppressors in the PS-PRO will absorb the excess voltage invisibly and harmlessly. However, if lightning strikes the actual building where the PS-PRO is installed (or somewhere very nearby), some damage may be unavoidable due to the extremely high voltage and current present. If this does occur, most likely damage will be limited to the PS-PRO itself and will affect only certain spike suppression components (called varistors or MOV’s.) In this “suicide” mode, the PS-PRO may sustain minor damage but generally will protect all equipment plugged into it from much more serious and costly damage as long as that equipment is properly grounded. Proper grounding requires the use of three-prong AC cords, and that the building’s outlets are actually grounded to earth as specified by the National Electrical Code.
Any PS-PRO known to have taken a direct lightning hit should be checked by a qualified technician or the Furman factory to determine whether the MOV’s need replacement. (If the PS-PRO’s PROTECTION OK indicator is not lit, there is definitely some damage. Some spike suppression capability may still be available by MOV Bank #2, but there is no guarantee of this.) For optimum protection, you should not rely exclusively on the PS-PRO to protect against a direct lightning hit. The first line of defense against
lightning should be a lightning arrestor installed on your building’s electrical service entrance. If your building does not have one, contact your local power company or an electrical contractor to have one installed.
THREE YEAR LIMITED WARRANTY
The Furman PS-PRO is protected by a limited three year warranty, covering defects in materials and workmanship, provided that the registration card is filled out and returned by the customer. Otherwise, a one year warranty applies. Products must have a proof of purchase from a Furman authorized dealer. During this period, Furman will make any necessary repairs without charge for parts or labor. Shipping charges to the factory or repair station must be prepaid by the owner; return shipping charges (via UPS Ground) will be paid by Furman.
This warranty applies only to the original owner and is not transferable. Also, it does not apply to repairs done other than by the Furman factory or Authorized Repair Stations.
This warranty shall be cancelable by Furman at its sole discretion if the PS-PRO unit has been sub- jected to physical abuse or has been modified in any way without written authorization from Furman. Furman’s liability under this warranty is limited to repair or replacement of the defective unit.
Furman will not be responsible for incidental or consequential damages resulting from the use or misuse of its products. Some states do not allow the exclusion of incidental or consequential damages, so the above limitations may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Warranty claims should be accompanied by a copy of the original purchase invoice showing
