BULLETIN:  42-799.0
EFFECTIVE:  March 2004

Service Policy

Owners of Magnetrol/STI controls may request the return
of a control or any part of a control for complete rebuild-
ing 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:

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 con-
trol; 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.

No claims for misapplication, labor, direct or consequen-
tial damage will be allowed.

Return Material Procedure

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’s/STI’s local representative or
by  contacting the factory. Please supply the following
information: 

1. Company Name
2. Description of Material
3. Serial Number
4. Reason for Return
5. Application

Any unit that was used in a process must be properly
cleaned in accordance with OSHA standards, before it is
returned to the factory.

A Material Safety Data Sheet (MSDS) must accompany
material that was used in any media.

All shipments returned to the factory must be by prepaid
transportation.

All replacements will be shipped F.O.B. factory.
