Chapter 3: Getting Started
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
3 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
3 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

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
Product Service 1-800-522-7658

Chapter 4: Performance Features and Safety Precautions
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.
Figure 4-1

Chapter 4: Performance Features and Safety Precautions
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 singleuse, 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.

Chapter 4: Performance Features and Safety Precautions
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
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.

Chapter 4: Performance Features and Safety Precautions
Safety Precautions
For all models:
NEVER expose ANY EVIDENCE, plastic or coated materials to ultraviolet
(UV) radiation. Never bypass the UV safety interlock that only allows the
UV light to work when the door is closed. UV exposure to the skin is
hazardous and can result in serious eye or skin injury.
Ensure that the cabinet is connected to electrical service in accordance with
local and national electrical codes. Failure to do so may create a fire or
electrical hazard. Do not remove or service any electrical components
without first disconnecting the cabinet from electrical service.
NEVER use this cabinet as a chemical storage cabinet.
When handling evidence, or working in the cabinet, always wear appropriate
personnel protective equipment.
NEVER attempt to dry evidence containing flammable gases or solvents in
the cabinet. An open flame should NOT be used in the cabinet.
HEPA filters only remove particulate matter. Operations generating volatile
toxic chemicals are prohibited. The media of the filter is fragile and should
not be touched. Avoid puncturing the HEPA filter during installation or
normal operation. If you suspect that a HEPA filter has been damaged, DO
NOT use the cabinet; contact Labconco at 800-821-5525 or 816-333-8811 for
further information.
The HEPA filters in the cabinet will gradually accumulate airborne
particulate matter from the items placed in the cabinet. The rate of
accumulation will depend upon the cleanliness of the air, operating time and
the nature of items being dried in the cabinet.
Do not operate the cabinet without all of the appropriate filters in place. If an
odor is detected coming out of the granular activated carbon, it needs to be
replaced.
The weight limit for the fold down shelves is 15 lbs (6.8 kg), and the floor of
the cabinet and lower storage area is 20 lbs (9.1 kg).
When surface disinfecting the cabinet:
• Always wear appropriate personnel protective equipment.
• NEVER use high pressure water to clean the liner; this practice could
generate biohazardous aerosols.
• NEVER spray disinfectants into the blower intake at the top of the
liner; this may damage the blower.
• Avoid splashing the disinfecting solution on skin or clothing.
• Ensure adequate room ventilation.
• Carefully follow the disinfectant’s safety instructions.
Product Service 1-800-522-7658
11
Chapter 4: Performance Features and Safety Precautions
• Always dispose of disinfecting solutions in accordance with local and
national laws.
• DO NOT allow bleach or disinfectants with high concentrations of
free chlorine to contact the stainless steel components of the
cabinet for a long period of time. Free chlorine will corrode
stainless steel after extended contact.
When handling used filters or prefilters, always wear appropriate personnel
protective equipment.

Fan/UV Light Switch
The cabinet Fan/UV Light switch is located on the upper front of the cabinet,
as shown in Figure 5-1. Turning the switch to the “Fan” position starts the
blower, drawing air into through the cabinet. Turning the switch to the “UV
On” position will allow the UV light to turn on when the door is closed and
the UV Security lock is in the “ON” position.
UV Security Lock
The UV security lock, located to the right of the Fan/UV Light switch, allows
the user to lockout the UV, preventing its operation. Before evidence is
loaded into the cabinet, it is recommended that the lock be turned to the
“OFF” position, and the key removed. This will prevent the accidental
activation of the UV light while evidence is drying. The key should be stored
in a convenient, secure location, known to all of the users to prevent its loss.
Recommended locations include hanging from the bar at the top of the liner,
or in the lower storage area.
Filter System Light
The Filter System Light will illuminate if the differential pressure across the
filters becomes excessive. If lit, first inspect or replace the two prefilters. If lit
with clean prefilters, replace the HEPA filter.
NOTE: If the Filter System Light illuminates during use, finish the drying of
the evidence in the cabinet, and then correct the problem before using the
cabinet again.

Chapter 6: Maintaining the Cabinet
Changing the UV Lamp:
Note: For optimum performance, the UV lamp should be changed on an
annual basis.
The UV lamp and the work area of the cabinet must be thoroughly
decontaminated before removing the lamp.
1. Thoroughly surface decontaminate the UV lamp and the work area of the
cabinet.
2. Unplug the cabinet, and open the door.
3. Remove the UV lamp by rotating it 90 degrees and lifting it straight up
and out of its sockets.
4. Install new lamp by reversing the removal procedure.
Resetting a Circuit Breaker:
To reset any of the circuit breakers located on the top rear of cabinet, depress
the white button until it sets.
Figure 6-4
Setting the Speed Control
Adjustment of the speed control varies the volume of air drawn through the
liner while the unit is operating. Ideally, smoke released into the intake
prefilter should traverse the liner, and be drawn into the exhaust prefilter in
approximately 5 seconds or less.
Using a small screwdriver, adjust the speed control to give the required face
velocity. See Figure 6-4 to locate the speed control. The air velocity is
increased by turning the speed control counter clockwise and clockwise to
decrease velocity.
