Section 1 Introduction

Your satisfaction and safety are important to Thermo and a complete

understanding of this unit is necessary to attain these objectives.

Warning As a routine laboratory precaution, always wear safety glasses

when working with this apparatus. ▲

This product is not intended, nor can it be used, as a sterile or patient

connected device. In addition, this apparatus is not designed for use in

Class I, II or III locations as defined by the National Electrical Code.

Save all packing material until unit is put into service. This merchandise

was carefully packed and thoroughly inspected before leaving our factory.

Responsibility for safe delivery was assumed by the carrier upon acceptance

of the shipment; therefore, claims for loss or damage sustained in transit

must be made upon the carrier by the recipient as follows:

1. Visible Loss or Damage: Note any external evidence of loss or damage

on the freight bill, or express receipt, and have it signed by the carrier's

agent. Failure to adequately describe such external evidence of loss or

damage may result in the carrier's refusing to honor your damage

claim. The form required to file such claim will be supplied by the

carrier.

2. Concealed Loss or Damage: Concealed loss or damage means loss or

damage which does not become apparent until the merchandise has

been unpacked and inspected. Should either occur, make a written

request for inspection by carrier's agent within fifteen (15) days of the

delivery date; then file a claim with the carrier since the damage is the

carrier's responsibility.

If you follow the above instructions carefully, we will guarantee our full

support of your claim to be compensated for loss or concealed damage.

Note Do not - for any reason - return this unit without first obtaining

authorization. In any correspondence to Thermo, please supply the

nameplate data, including catalog number and serial number. ▲
