2. SAFETY WARNING

This analyser extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted from the side of the instrument. This instrument must only be used in well ventilated locations. It must only be used by trained and competent persons after due consideration of all the potential hazards.

Protection Against Electric Shock (in accordance with EN 61010-1 :

1993)

This instrument is designated as Class III equipment and should only be connected to SELV circuits. The battery charger is designated as:

Class II equipment Installation category II Pollution degree 2 Indoor use only Altitude to 2000m Ambient temperature 0°C-40°C Maximum relative humidity 80% for temperatures up to 31°C decreasing linearly to 50%RH at 40°C Mains supply fluctuations not to exceed 10% of the nominal voltage.

3. FIRST TIME USE

Charge the battery for 12 hours. Following this, an overnight charge should be sufficient for an average 8 hour day. See Main Parameter displays for Battery Indicator.

The KANE900 Plus has a rechargeable lead acid battery which uses a different charger than other Kane analysers. Ensure the correct charger is used or damage

may occur to the instrument.

Check that you have all the items you have ordered. Take time to read this manual fully. Be aware that the analyser configuration that you have purchased may not support all the features detailed in this manual. When using the analyser for the first time you will need to choose from: Language selection Calibration countdown time CO gas alarm NOx percentage for calculation Time and Date Printed header name and telephone number

The SET UP MENU (Section 5.2.5) gives details of how to change the above settings.

4. NORMAL START UP SEQUENCE

4.1 Every Time You Use The Analyser

BEFORE SWITCH-ON CHECK THAT:

the particle filter is not dirty

the water trap and probe line are empty of water

all hose connections, etc, are properly made

the probe is sampling CLEAN AMBIENT air

the water trap is correctly fitted and the instrument upright

the flue temperature is connected

Switch ON the instrument by pressing

4.2 Automatic Calibration

During this sequence the analyser pumps fresh air into the sensors to allow toxic sensors (if fitted) to be set to zero and the Oxygen sensor to be set to 20.9 %.

After switch-on the analyser will briefly display header information :-

Kane International

(44)-1707-375550

And then show the countdown screen :-

ZERO CAL

Time : 180

FRESH AIR PURGE

The calibration time will count down in seconds to zero. Calibration time may be changed from 2 to 6 minutes. See Set-Up menu section 5.2.5.

Note ! Three minutes is recommended to allow the sensors to stabilise fully. Anything

less than this may result in drift of the toxic and oxygen sensors in clean ambient air.

To obtain the quoted specification an instrument should be calibrated with clean ambient air at standard temperature and pressure (STP).

Once the time has reached zero an audible beep will be heard and will show the selected fuel on the following display:-

4.3 Main Displays

The main display can be changed to show either 4 or 8 parameters at one time. Two options are available when 4 parameters are selected.

• 4 Page Mode displays 4 lines of data in set format, each page is predefined.

• Line scroll mode allows you to customise the display to show the data you

require.

• 8 Page Mode displays 8 parameters on 4 lines in set format, the bottom two can be

changed.

Changing between the different modes is detailed in Display Menu Section 5.2.4.

4.3.1 4 Page Mode

Use the and keys to change the information that is displayed on the screen. The following pages are available.

Use the and keys to change the bottom line of the display. Once the

correct line is displayed press to confirm and move the line up. Select the next parameter and repeat until all lines display the desired parameters.

4.4 Sampling the Flue Gas

Once the automatic calibration procedure has been completed and the specific fuel has been selected (See SELECT menu) the probe can be inserted into the desired sampling point.

It is recommended that the sampling point be located at least two flue diameters downstream of any bend and that the probe tip is in the centre of the flue. With balanced flues and other domestic units the probe should be positioned far enough into the flue so that no air can ‘back flush’ into the probe. This will be indicated by a low oxygen reading and/or a low ‘Poison Index’ reading.

The probe depth stop cone provided with the instrument allows the probe to be used in holes whose diameters range from 8 mm to 21 mm (5/16 to

The standard probe is rated at 650°C (1202oF). Temperatures of up to 1200°C (2200°F) can be accommodated using an optional high temperature probe.

TIP To conserve battery power, switch off the pump when you are not taking a

measurement. Use the

key to turn ON and OFF the pump.

/16 inch).

4.5 Taking a Pressure Reading

With the optional pressure module fitted a flue draught measurement can be made at any time.

Connect the standard probe to the pressure sensor inlet and the probe in the flue. The pressure reading will be displayed :-

CO/CO2 R 0.0001 P INDEX % 0.01 XAIR % 0.0 Prs mbar 0.00

To perform a combustion test and display draught pressure at the same time a special probe is required. Contact Kane International or Authorised Distributor for details.

4.6 Regular Checks During Sampling

Care must be taken at all times not to exceed the analysers operating specifications, in particular ensure the following :-

• Do not exceed the maximum temperature of the flue probe.

• The analyser internal temperature does not exceed normal operating range, typically 0-50°C.

• DO NOT PLACE THE INSTRUMENT ON A HOT SURFACE.

• The water trap is vertical at all times. Water condenses in the probe line and can

quickly fill the water trap when the probe is moved. Take care and watch the water trap closely.

• The in-line particle filter is clean and does not become blocked.

4.7 Normal Shutdown Sequence

DO THIS EVERY TIME YOU USE THE ANALYSER

Remove the probe from the flue - TAKE CARE ! THE PROBE WILL BE HOT - and allow it to cool naturally. Do not immerse the probe in water as this will be drawn into the analyser and damage the pump and sensors.

Once the probe is removed from the flue press and the analyser will count down from 30 to switch off.

OFF 30

MENU TO ESCAPE

If you have not finished but press by mistake, you can press to return to normal operation and not switch OFF.
