9.0 WARRANTY 9.0 WARRANTY
ENMET warrants new instruments to be free from defects in workmanship and material under normal use for a period
of one year from date of shipment from ENMET. The warranty covers both parts and labor excluding instrument
calibration and expendable parts such as calibration gas, filters, batteries, etc... Equipment believed to be defective
should be returned to ENMET within the warranty period (transportation prepaid) for inspection. If the evaluation by
ENMET confirms that the product is defective, it will be repaired or replaced at no charge, within the stated
limitations, and returned prepaid to any location in the United States by the most economical means, e.g. Surface
UPS/RPS. If an expedient means of transportation is requested during the warranty period, the customer is responsible
for the difference between the most economical means and the expedient mode. ENMET shall not be liable for any
loss or damage caused by the improper use of the product. The purchaser indemnifies and saves harmless the
company with respect to any loss or damages that may arise through the use by the purchaser or others of this
equipment.
This warranty is expressly given in lieu of all other warranties, either expressed or implied, including that of
merchantability, and all other obligations or liabilities of ENMET which may arise in connection with this equipment.
ENMET neither assumes nor authorizes any representative or other person to assume for it any obligation or liability
other than that which is set forth herein.
9.1 Repair of Certain Units
The warranty does not apply to equipment returned in either of the conditions defined below. These are not the result
of defective workmanship or material. We will renovate and return at owner's expense.
a) Gross Recalibration: We calibrate all ISA – M according to the customer order before shipping. Changing the
potentiometers voids the warranty, except when following the calibration procedures (Sec. 6.0). When we receive
such a unit for repair, and no defects exist, we will diagnose the problem and recalibrate the unit according to the
original order.
b) Gross Sensor Contamination: The MOS sensor is durable. It can be purged of normal contaminants by operating
the unit in the PURGE mode for a sufficient length of time. Gross contamination usually occurs during misuse.
Here are three examples of gross sensor contamination:
Close exposure to an open gas flame.
Dipping the sensor in lacquer.
Continuous exposure to heavy concentrations of industrial vapors.
NOTE: When returning an instrument to the factory for service:
§ Be sure to include paperwork.
§ A purchase order, return address and telephone number will assist in the expedient repair and return of your unit.
§ Include any specific instructions.
§ For warranty service, include date of purchase
§ If you require an estimate, please contact ENMET Corporation.
There are Return for Repair Instructions and Form on the last pages of this manual. This Form can be copied or used
