How To Unpack the Type 870/872 Unit
MKS has carefully packed the Type 870/872 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.
Ultraclean Units
The 870/872 transducer is an ultraclean unit that is assembled in a class 100 clean room
environment. The unit is carefully purged with clean dry nitrogen and sealed to ensure
maintenance of its particle free condition during shipment. It is very important to remove the bags
according to clean room practices. To maintain at least a minimal level of clean room standards,
follow the instructions below.
1. Remove the outer bag in an ante room (garmenting room) or transfer box.
Note Do not allow this outer bag to enter the clean room.
2. Remove the inner bag in the clean room.
