a negative control.

1. Remove sealing labels from a new casse e and a ach to adapter without
disturbing adapter tubing in wall.

Calibration and Preparation

1. Calibrate sample pump with representative VersaTrap® Casse e in line
to desired fl ow rate (15 L/min is recommended for VersaTrap). Remove
casse e a er calibration.

2. Use drill with bit to create a 3/8-inch hole in wall 3 to 6 inches from fl oor.

Caution: Drill slowly to minimize aerosolization of gypsum dust.

3. Insert angled end of VersaTrap Wall Adapter tubing into hole.

4. Prepare a "vacuum" casse e by removing labels from inlet and outlet of a
casse e. A ach rectangular end of adapter to casse e inlet. Use "vacuum"

casse e only to collect excess dust.

Flow Rate: 15 L/min
Sample Time: 2 minutes

2. Turn on pump and sample for two minutes.

3. Disconnect adapter and casse e. Before replacing sealing labels on casse e,
hold it up to the light. If you cannot see through the slide, discard casse e
and take another sample. Continue sampling until a usable sample is
obtained.

4. Seal casse e inlet and outlet with sealing labels, label casse e, and ship
with blanks to a laboratory for analysis. Go to www.skcinc.com for a list of

laboratories that analyze VersaTrap Casse es.

Wall Sampling Considerations

1. Sample location. Total counts may vary in diff erent types of wall cavities.

E.g., a four-foot wall versus a 12-foot plumbing wall will diff er in volume
of air within the wall cavity.

2. Moisture level. Excessive moisture in a sample location can prevent

microbial contaminants from becoming airborne.

3. Gypsum dust. If gypsum dust is trapped inside the casse e, accurate

microscopic analysis cannot be performed because the dust will mask
mold spores. Following the guidelines in this operating instruction
should help minimize the collection of dust when using this device.
