Maintenance
6.2 Water Trap / Filter Maintenance
6.2.1 Emptying the Water Trap Chamber
The water trap chamber should be emptied after every test, or when the
water condensate approaches the tip of the riser tube (refer to Section 4.9).
1. Remove water trap chamber per Figure 6-5.
2. Pour out liquid condensate, and then reassemble trap.
6.2.2 Replacing the Filter Element
Replace the filter element when it becomes visibly dirty or becomes satu-
rated with water.
Material Required: • Filter Element, P/N 07-1644
• Small Flat Blade Screwdriver
1. Remove water trap chamber per Figure 6-5.
2. Pry apart filter chamber using a small flat-blade screwdriver. Remove
and discard old filter.
3. Install new filter and reassemble filter chamber, making sure that
surfaces "A" and "B" contact each other.
4. Reassemble trap.

Initial Setup

3.2.2 Using the AC Power Adapter

The AC power adapter is capable of powering the analyzer on a continuous
basis. The adapter plugs into an appropriate 100–240 VAC, 50/60 Hz wall
outlet, and produces an output of +9 VDC. The adapter's output connector
plugs into the analyzer's POWER jack located on the bottom of the unit
(Figure 3-2).
If NiMH rechargeable batteries are used, the adapter can also rapid
charge these batteries in approximately 2 - 3 hours while still inside the
analyzer. For the batteries to be charged, however, the analyzer's battery
charger circuit must be turned ON per Section 3.16.

3.3 Connecting the Probe and Hose Assembly

Do the following to attach the probe and hose assembly to the analyzer
(Figure 3-2):
Instruction 24-9448 3-2
1. Push the gas-sample hose connector, the larger of the two connectors (giv-
ing a slight twist), onto the analyzer's GAS fitting.
2. Push the draft-hose connector, the smaller connector (giving a slight
twist), onto the analyzer's +∆P fitting.
3. Push the stack-gas thermocouple connector into the T-STACK jack (connec-
tor fits in only one way).
NOTE: The analyzer has a built-in temperature sensor for mea-
suring ambient temperature. Perform Step 4 only if the optional
primary / ambient air thermocouple is used.
4. Push the optional primary / ambient air thermocouple into the T-AIR
jack (connector fits in only one way).
IMPORTANT: To assure the accurate calculation of combustion
efficiency, the optional primary / ambient air thermocouple must
be used when the burner's primary-air temperature is not the
same as the room temperature.
5. Inspect all hoses for cracks. If any hose is found to be defective, replace
the entire probe and hose assembly. Check that the water trap is
empty, and that the filter is not dirty or saturated with water.
