7.1 Warranty Repairs 

During the Warranty period, Spellman will repair all units 
free of charge. The Warranty is void if the unit is worked 
on by other than Spellman personnel. See the Warranty in 
the rear of this manual for more information. Follow the 
return procedures described in Section 7.2. The customer 
shall pay for shipping to and from Spellman. 

 

7.2 Factory Service Procedures 

Spellman has a well-equipped factory repair department. 
If a unit is returned to the factory for calibration or repair, 
a detailed description of the specific problem should be 
attached. 

For all units returned for repair, please obtain an 
authorization to ship from the Customer Service 
Department, either by phone or mail prior to shipping.  
When you call, please state the model and serial numbers, 
which are on the plate on the rear of the power supply, 
and the purchase order number for the repair.  A Return 
Material Authorization Code Number (RMA Number) is 
needed for all returns.  This RMA Number should be 
marked clearly on the outside of the shipping container.  
Packages received without an RMA Number will be 
returned to the customer.  The Customer shall pay for 
shipping to and from Spellman. 

A preliminary estimate for repairs will be given by phone 
by Customer Service.  A purchase order for this amount is 
requested upon issuance of the RMA Number.  A more 
detailed estimate will be made when the power supply is 
received at the Spellman Repair Center.  In the event that 
repair work is extensive, Spellman will call to seek 
additional authorization from your company before 
completing the repairs. 

7.3 Shipping Instructions 

All power supplies returned to Spellman must be sent 
shipping prepaid.  Pack the units carefully and securely in 
a suitable container, preferably in the original container, if 
available.  The power supply should be surrounded by at 
least four inches of shock absorbing material.  Please 
return all associated materials, i.e. high voltage output 
cables, interconnection cables, etc., so that we can 
examine and test the entire system. 

All correspondence and phone calls should be directed to:
