Installation

MicroTech I Display and Board Removal

Once each of the wires is labeled, unplug all wires from MCB, 

Output Board, and Input Board. Leave all paired wires in their 

respective plugs to keep them organized. Unscrew each of 

the boards from the control panel. Remove the wires from the 

back of the MT I Display. Unscrew the display and remove from 

control panel. 

Figure 5

 below shows the control panel with all 

wiring labeled and boards removed.

Removing Temperature Sensors, Pressure Sensors and Pressure 

Switches

The following temperature sensors will need to be removed 

from the unit: DAT, RAT, MAT, EWT. Be aware and take note of 

the mounting location for each of these sensors because new 

sensors will be remounted and wired to the MT III MCB later on 

in this manual. 
If the PC5, PC7 and DHL tubing does not need replacing, then 

save existing tubing. Be aware and take note of the high and 

low side of pressure designations to avoid erroneous readings 

after install.
