How To Unpack the Type 649 Unit
MKS has carefully packed the Type 649 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 RMA Number (Return Material 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.
Opening the Package
The 649 controller is assembled, leak tested with helium, and calibrated in a clean room
environment. The instrument is double-bagged in this environment to ensure maintenance of its
particle free condition during shipment. It is very important to remove the packaging according
to clean room practices. To maintain at least a minimal level of clean room standards, follow the
instructions below.
1. Remove the container in an ante room (garmenting room) or transfer box.
Do not allow this container to enter the clean room.
2. Remove the inner bag in the clean room.
Caution
Only qualified individuals should perform the installation and any
user adjustments. They must comply with all the necessary ESD and
handling precautions while installing and adjusting the instrument.
Proper handling is essential when working with all highly sensitive
precision electronic instruments.
