Warning As a routine laboratory precaution, always wear safety glasses
when working with this apparatus. s
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.
Warning If this equipment is not used as specified in this manual, the
protection provided by the unit design may be impaired. s
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

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.
