SAMPLING PUMP

1. Attach the Sampling Hose or Sampling Probe directly to the Sampling Pump. Turn

the quick connect right to lock into place.

TO ACTIVATE THE PUMP

2. Simply slide the thumbswitch fully to the

right closing the vents. The pump will

automatically turn ON, drawing the

sampled air across the sensors. The

Sampling Pump Fan Icon will light.

During pump operation, the BW

DEFENDER will display the FAN icons in

a “spin” pattern. This indicates that the

pump is operating normally.

Allow 2 minutes or more for the sample to

travel up the sample tubing (dependent on

the length of the tubing).

TO RETURN TO AMBIENT MODE

3. Slide the thumbswitch fully left, opening the vents, which allows the ambient air to

reach the sensors via normal diffusion. The pump will automatically turn OFF.

LOW FLOW ALARM

GENERAL: Should the Hose (Probe) or Pump become clogged or plugged, the

BW DEFENDER unit will go into alarm. All Alarm indicators will pulse rapidly.

VISUAL ALARMS: The FAN icon will flash ON and OFF

The “HIGH ALARM” icon will flash

The LED Alarms will flash

AUDIBLE ALARMS: The Audible Beeper will sound in a fast intermittent

pulse

1. Turn the pump OFF immediately. Slide the Pump's thumbswitch fully left opening

the vents.

2. Clear obstruction before proceeding. Clean out clogged tubing probe by blowing it

out or flushing with clean water and drying. Wash and dry clogged blue Particulate

Filter (or replace). Check the clear cap to see if water has reached the pump trap

(see page 18).

SAMPLING PUMP

HYDROPHOBIC FILTER: The replaceable hydrophobic Teflon filter should be

inspected periodically to ensure that it is clean. Dirty filters will impede airflow into the

BW DEFENDER unit, and should be replaced as soon as possible.

WATER INVASION: Due to design, water

is unlikely to reach the pump housing. But,

in the event it does, open the housing and

drain the liquid from the built-in water trap.

Dry the filter.

1. Remove the 3 screws holding the clear

cap in place.

2. Drain out any liquid and air dry the filter.

If the filter is dirty or damaged, remove

the old filter.

3. Put the new filter in place overtop the

adhesive ring and lightly press into

place. Be certain the filter does not

obscure the nutserts and is correctly

aligned.

4. Replace the clear cap, ensuring the

three Phillips screws are fully seated

and the filter is in the correct position.
