PCA
Instruction 24-9351
3.2.2 Using the Optional Power Supply
If an Optional Power Supply is to be used:
1. Connect the output plug of the Optional Power Supply to the
analyzer’s power supply jack (Figure 3-2).
2. Plug the Optional Power Supply into an appropriate AC wall outlet.
The analyzer will now operate and function normally.
3.3 Connecting the Probe
To attach the probe to the analyzer (Figure 3-2):
1. Push the yellow-banded, quick-connect Flue Gas Hose (giving a slight
twist) onto the analyzer’s GAS sample-inlet fitting.
2. Push the blue-banded, quick-connect Draft Hose (giving a slight twist)
onto the analyzer’s DRAFT sample-inlet fitting.
3. Push the Flue Gas Thermocouple into the T-STACK jack (connector
fits in only one way).
NOTE: The PCA has a built in room-air thermocouple.
Perform Step 4 only if the Optional Room Air/Primary Air
Thermocouple is used.
4. Push the Optional Room Air/Primary Air Thermocouple into the
T-AIR jack (connector fits in only one way).
NOTE: In order for the PCA to correctly calculate combus-
tion efficiency when the burner’s primary-air temperature is
not the same as room temperature, the primary-air tempera-
ture should be measured using the optional Primary Air
Thermocouple.
Inspect all the hoses for cracks. If any hose is defective, replace the entire
probe assembly. Check that the water trap is dry and the filter is not
dirty or saturated with water.
