  CUSTOMER SERVICE

Intek's corporate philosophy is to solve our customer's difficult flow measurement/monitoring problems.
This means that each instrument is custom configured and calibrated for the application.  When you
purchase a 

Rheotherm

 instrument you also receive Intek's outstanding customer service.  For sales or

product service, call your local representative or Intek directly at (614) 895-0301 8AM to 5PM EST/EDT
weekdays or fax us anytime at (614) 895-0319.  Our customer service staff will provide assistance
promptly.  Our website at 

www.intekflow.com

 is available for additional information; for submitting

.

5.1 QUESTION ON EXISTING HARDWARE

To allow us to help you more quickly, please have the serial number of the equipment available before
you call.  If your company is not the original purchaser the identity of the original recipient will also be
helpful.

5.2 TROUBLE SHOOTING

If you have reviewed SECTION 4.3 TROUBLE SHOOTING and have questions, please call our
experienced engineers for assistance.  In many cases we can solve a problem over the phone.  Please
provide as complete a description as possible of the problems encountered.

5.3 FACTORY AND FIELD SERVICE

Model 400 flow switch/monitor cannot be serviced in the field.  If a problem cannot be solved through
a telephone conversation with one of our engineers, the unit should be returned to the factory for
inspection.

To request factory service, a Return Material Authorization (RMA) and purchase order is required.  Our
customer service staff will assist you with the required information to return instruments for service.

5.4 DECONTAMINATION OF EQUIPMENT

For the safety of your personnel and ours, any hardware that has been in contact with potentially
hazardous liquids or gases must be properly decontaminated before shipment to Intek.
