CAUTION: DO NOT DISTURB THE INTEGRITY OF THE CELL
PACKAGE UNTIL THE CELL IS TO ACTUALLY BE
USED. IF THE CELL PACKAGE IS PUNCTURED AND
AIR IS PERMITTED TO ENTER, CELL-LIFE WILL BE
COMPROMISED.
3.2 Location and Mounting
This instrument should be installed at viewing level either indoors
or sheltered from the moisture and the elements and mounted so it won’t
be subject to vibration. The ambient temperature should be within the
range of 0-50°C (32-122°F). For the best performance, do not exceed
40°C (104°F).
In choosing a location for the analyzer, select a site that is as close
as possible to the sample extraction point. This will enhance the overall
instrument response time. If the analyzer is to be mounted in direct
sunlight, minimize the solar heating by orienting it in a north or south
facing direction.
3.2.2 Installing the Micro-fuel Cell
A Micro-fuel Cell is included as a separate item. It must be
installed prior to instrument use.
Also, once it is expended, or if the instrument has been idle for a
lengthy period, the Micro-fuel Cell will need to be replaced.
During the Installation and/or Replacement of the MFC, the
membrane surface MUST ALLWAYS FACE DOWNWARD
TOWARD THE CELL CAP. The concentric gold contacts must
face up.
To install or replace the Micro-fuel Cell, follow the procedures in
Chapter 5, Maintenance.
3.3 Electrical Connections
Figure 3-1 shows the Model 3300T/OT-3 rear panel of the control
unit. (See Figure 1-3 for DC version). To gain access to the terminal
blocks, the analyzer door screws must be loosened, and the door opened.
