Chapter Two: Installation
How To Unpack the Type 253 Unit
MKS has carefully packed the Type 253 unit so that it will reach you in perfect operating order.
Upon receiving the unit, however, you should check for defects, cracks, broken connectors, etc.,
to be certain that damage has not occurred during shipment.
Note
Do not discard any packing materials until you have completed your
inspection and are sure the unit arrived safely.
If you find any damage, notify your carrier and MKS immediately. If it is necessary to return the
unit to MKS, obtain an ERA Number (Equipment Return Authorization Number) from the MKS
Service Center before shipping. Please refer to the inside of the back cover of this manual for a
list of MKS Calibration and Service Centers.
