Serial Numbers Compensation Policy Bosch will authorize reasonable travel and standard labor costs and expenses for the required service. Documentation is required for all costs. Policy Termination Date: March 31, 2015 Any Questions please contact Bosch Technical Support at 866 642-3198. See Table 1 - List of Units Affected. Reference Documents MANDATORY REWORK - Background Bosch Thermotechnology has been informed by the manufacturer that some of its transformers with integral circuit breaker, FHP part number T-111-603-026, may not open if an over-current condition occurs. Although it is highly unlikely, an over-current condition might create an over-heating situation with a potential of a fire and/ or shock hazard. No such incidents have been reported. Bosch has identified 128 shipped units that may contain the affected transformer. These units were shipped between September 2014 and November 2014. All affected serial numbers are listed in Table 1. Units not on the list are not affected. This rework does not impact spare parts shipped from Bosch. Replacing the Transformer Technical Service Bulletin Document part number: BTC 760002103 Labor Request Form Document part number: BTC 760002104 Required Field Action FHP WSHP products with serial numbers listed in Table 1 (List of Units Affected) require replacement of the transformer part number T-111-603-026. Bosch will contact each customer directly and will provide a replacement part free of charge for all WSHP products listed in Table 1. Upon replacing the nonconforming transformer (see Attachment 1 - Rework Instructions), it is required to complete the Labor Request Form (see Attachment 2), and return as indicated to receive proper credit for labor and travel. All nonconforming transformers replaced in the field are required to be returned to Bosch using the original box used for delivery of the replacement transformer and the prepaid return shipping label. Bosch will issue a Returned Material Authorization (RMA) for the parts to be returned at the time the free of charge order is created. Data subject to change without notice BTC 760004103 A 12.2014
