Chromalox 3101 Operator's Manual 3
Section 2
Installation
On receipt of your 3101 controller, immediately
make note of any visible damage to the ship-
ment packaging and record this damage on the
shipping documents. Unpack the controller and
carefully inspect it for obvious damage due to
shipment. If any damage has occurred, YOU must
fi le a claim with the transporter, as they will not
accept a claim from the shipper.
If the controller will not be immediately installed
and placed into operation, it should be stored in
a cool, dry environment in its original protective
packaging until time for installation and operation.
Temperature extremes and excessive moisture
can damage the instrument.
