Obtaining Warranty Parts

through Friday from 8:00 a.m. to 5:00 p.m. EST. A service technician at STULZ will assist in troubleshooting
the system over the telephone with a field service technician to determine the defect of the part. If it is
determined that the part may be defective a replacement part will be sent via UPS ground. If the customer
requests that warranty part(s) be sent by any other method than UPS ground the customer is responsible for
the shipping charges. If you do not have established credit with STULZ you must give a freight carrier account
number.

same day shipment. The purchase order must contain the following items:
