SERVICE POLICY
RETURN MATERIAL PROCEDURE
Owners of Magnetrol/STI controls may request the return of
a control or any part of a control for complete rebuilding or
replacement. They will be rebuilt or replaced promptly.
Controls returned under our service policy must be returned
by Prepaid transportation. Magnetrol/STI will repair or
replace the control at no cost to the purchaser (or owner)
other than transportation if:
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material Authorization”
(RMA) number be obtained from the factory, prior to the
material's return. This is available through Magnetrol/STI's
local representative or by contacting the factory. Please supply the following information:
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim to be
covered under the warranty.
If the trouble is the result of conditions beyond our control;
or, is NOT covered by the warranty, there will be charges for
labor and the parts required to rebuild or replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If this is
desired, notify the factory of both the model and serial numbers of the control to be replaced. In such cases, credit for
the materials returned will be determined on the basis of the
applicability of our warranty.
