1. Run the line voltage through the bulk-

head fitting on the bottom of the MPS

where marked LINE IN, Figure 2-18.

Refer to Figure 2-19. Connect the line

voltage to the LINE IN terminal on the

MPS terminal board located inside the

unit. Tighten the cord grips to provide

strain relief.

2. The MPS can accommodate up to four

probes. The terminal strips on the MPS

termination board are marked PROBE

1, PROBE 2, PROBE 3, and PROBE 4.

Select PROBE 1 if this is the first probe

and electronic package installed on the

MPS.

3. Make the connections from the MPS to

the IFT as shown in Figure 2-19. Run

wires from the MPS Termination Board

inside the unit through the bulkhead fit-

ting on the bottom of the unit where

marked SIGNAL IN, Figure 2-18. After

the connections are made, tighten the

cord grips to provide strain relief.

NOTE

Upon completing installation, make sure that the probe is turned on and operating

prior to firing up the combustion process. Damage can result from having a cold

probe exposed to the process gases.

During outages, and if possible, leave all probes running to prevent condensation and

premature aging from thermal cycling.

If the ducts will be washed down during outage, MAKE SURE to power down the

probes and remove them from the wash area.
