Nor-Cal PMXYZ Series Precsion Manipulator - Manual (Page 3)

High-Vacuum Containment and Control
Installation
******** WARNING *********
Shipping vibration can loosen screws. The user must check to verify the screw
fasteners have not backed off on the unit during shipment. This is critical for safe
operation.
***********THIS IS IMPORTANT ************
The standard PMXYZ Manipulator can be installed directly from the packing. As
usual, care should be exercised to protect the knife seal edge. The standard
units mount to a 2.75" or 6" OD flange. Proper tightening technique should be
observed whenever tightening a metal sealed flange. We recommend a small
quantity of high temperature anti-seize lubricant be used on all mounting bolts.
This is especially important if the unit will be subject to bake-outs.
********** WARNING *********
It is necessary, especially on longer stroke manipulators, to have an axis rod or
tube down the axis of the Z travel. This will keep the bellows from "springing" out
when the pressure is returned to atmosphere (usually when the unit is near its
most compressed mode). This function is usually satisfied by a "theta" rotation
shaft or support tube. Damage to the equipment can occur if this precaution is
not observed.
