Chromalox 2104 Technical Manual 3
Section 2
Installation
On receipt of your 2104 controller, immediately make
note of any visible damage to the shipment 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 file 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.

The 2104 has up to seven (7) hardware switches
located on the bottom of the controller. The switches
are accessible through cutouts in the controller
housing and do not require that you remove the
controller from its housing to access the switches.
Figure 2.1 identifies the switches. Instructions for
switch settings are given in the corresponding sections
of the manual.
