Initial Operation
Prior to use with evidence, you should perform the following operational tests to
ensure the cabinet is operating properly:
Airflow Smoke Pattern Test
With the cabinet fan ON, introduce smoke (from a cigarette,
chemical smoke stick, etc.) into the prefilter at the bottom of the
door. The smoke should flow directly into the cabinet, and then into
the upper prefilter located at the top of the cabinet liner. The smoke
should move from the door to the intake prefilter in approximately 5
seconds or less. If the smoke does not flow as described, see the
“Adjusting the Fan Speed” section of Chapter 6.
UV Light and Interlock Tests
With the door closed, turn the “Fan/UV Light” switch to “UV” and
the “UV Security Keylock to “ON”. The UV light will then turn on.
Open the door, and the UV light will turn off. Close the door, and
the UV light should relight. Turn the UV Security Keylock to the
“OFF” position, and the UV light will turn off. If the UV light does
not work as described, call Labconco’s Product Service Department
at 1-800-522-7658 or 816-333-8811.
Spray Gun and Drain Pump and Tests (Model # 34000-10 thru -14,
34040-10 thru 34040-14 & 34050-10 thru -14 only)
Open the cabinet door, and ensure that the drain strainer is in place.
Open the lower door, and turn the cabinet water supply valve on.
Use the spray gun in the “Shower” setting, ensuring proper
operation. Turn the gun and cabinet supply valve off. Push the
control switch to the “Drain Pump” position. The majority of water
should be pumped out of the cabinet and to the floor drain. Some
water may remain in the bottom of the cabinet due to surface
tension or the floor not being level. In this case, use a small
squeegee or sponge to direct the remaining water to the drain. Shut
off the drain pump when finished.

The Protector Evidence Drying Cabinet operates using the following principles:
Directional airflow.
Prefiltration of large particulates by an inlet prefilter (in the door) and an
exhaust prefilter (in the top of the liner).
Filtration and retention of particulates by a High Efficiency Particulate Air
(HEPA) filter.
Adsorption of organic (odorous) chemicals by a granular activated carbon
filter.
The major components in the cabinet are:
The prefilters
The blower to force air through the cabinet
The HEPA filter
The granular activated carbon filter

Directional Airflow
Directional airflow plays a critical role in evidence drying cabinet performance.
Air is drawn into the inlet prefilter, located on the bottom of the door. The filtered
air then flows upward through the liner, passing over the evidence to be dried.
Before leaving the liner, the air then passes through the exhaust prefilter, that is
designed to protect the HEPA filter from large particulates, and may be removed to
examine it for the collection of evidence. The air is pressurized by the blower, and
then forced through the HEPA and carbon filters, to remove biohazardous
particulates and odorous chemicals, respectively. This is illustrated in Figure 4-1.

Optional Evidence Prefilters
Optional Evidence Prefilters can be fitted on the inside (cabinet side) of the door
prefilter (located on the front of the door) and cabinet prefilter (located on the
inside top of the liner). These thin prefilters are designed for single-use, to be
removed after the evidence has dried. After removal, the Evidence Prefilters can be
examined for trace evidence, or stored with the evidence in a sealed bag for future
reference. See Appendix A for reorder part numbers.
Prefilters
Both the door prefilter (located on the front of the door) and cabinet prefilter
(located on the inside top of the liner) are disposable, polyester particulate filters.
Both filters have a Minimum Efficiency Reporting Value (MERV) of 11, meaning
they remove 65-79% of particles 1.0-3.0 microns in size, and more than 85% of
particles 3.0-10 microns in size. See Appendix A for reorder part numbers.
HEPA Filters
HEPA filters are disposable, dry-type particulate filters. The filter material or
media is typically made of borosilicate microfibers formed into a thin sheet, in a
process similar to the production of paper. This sheet is folded, or pleated to
increase its surface area. The pleats are held in place by aluminum diffusers or by
beads of glue that add rigidity to the media pack. The pack is then set into a frame,
and sealed as shown in Figure 4-2.
The HEPA filter manufacturer establishes the efficiency of the filter by challenging
it with an aerosol of known particle size. The number of particles that penetrate the
filter are quantified, and this establishes the efficiency of the filter. The filters used
in the evidence drying cabinets are at least 99.99% efficient in removing particles
0.3 micron.
Note: The HEPA filter media is very fragile. DO NOT touch the media. If
you think the media of a HEPA filter is damaged, DO NOT USE THE
CABINET. Call Labconco’s Product Service Department at 1-800-522-7658 or
816-333-8811.
Note: HEPA Filters are only effective against particulate material. Gases will pass
through the filter.

Blower
The blower assembly pulls room air into the intake prefilter on the front of the
door, through the liner and exhaust prefilter, and then forces it through the HEPA
and granular activated carbon filter. The evidence drying cabinet uses a motorized,
backward curved fan for quiet, energy efficient operation.
Cabinet Air Intake and Exhaust
In order to operate properly, the air intake at the bottom of the door, the exhaust
prefilter area in the top of the liner, and the top surface of the activated carbon
filter must be unobstructed. Blocking or restricting any of these areas, or allowing
the prefilters to become excessively loaded with dust can adversely affect the
performance of the cabinet.
Ultraviolet (UV) Lamp (Model # 34000-00 thru -04, 34040-00 thru -04
& 34050-00 thru -04 only)
The optional UV lamp generates a primary wavelength of light of 254nm. A
secondary emission is in the visible (blue) wavelength, resulting in the
characteristic blue color while operating. UV light with a wavelength of 254 nm is
biocidal, primarily by creating thymine dimers in DNA. These dimers prevent the
correct transcription of the DNA into RNA, resulting in cellular death or viral
inactivation. In order to be effective, the UV light must directly strike the nucleic
acid, and its effectiveness can be diminished or negated by dissolved proteins or
metals, or by other UV-opaque substances protecting the target nucleic acid.
Because of its limitations, UV light should be used as an adjunct to good surface
disinfection practices. In order to get optimum performance from the UV light, it
should be replaced after 6,000 hours of operation or less, and the exterior surface
of the lamp should be kept clean and free of dust.
Note: UV irradiation is absorbed by the tempered safety glass of the door.
Independent research has shown that the level of UV irradiation on the outside of
the cabinet’s door is equal to background radiation levels.
Note: The UV sensitivity of a target organism varies, depending on the UV output
of the lamp, the genus and species of the organism, the medium the agent is
suspended in, etc. Contact the Health and Safety Officer at your facility for UV
light use and recommendations.
