Service Policy

Owners  of  MAGNETROL  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 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, cred-
it  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  a  MAGNETROL  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.
