DESCRIPTION
The SCOTT C420 Plus respirator is a blower assisted Air Purifying respirator
referred to as a Powered Air Purifying Respirator or a PAPR. Training is required
before use.
The SCOTT C420 Plus PAPR is a modular design composed of replaceable subassemblies and may include certain SCOTT accessories. Each major subassembly and
accessory is labeled with its SCOTT part number. In order to maintain the NIOSH approved status of the respirator, use only those subassemblies and/or accessories listed
as applicable to a particular NIOSH approval number.
The complete SCOTT C420 Plus respirator consists of a SCOTT full facepiece
and head harness of the appropriate size to fit the user’s face, a breathing tube to
connect the facepiece to the blower assembly, and a blower assembly with a fresh
battery installed and fitted with two (2) matching filtration elements suitable for the
expected contaminants. A belt assembly supports the blower assembly on the user’s
waist. An Airflow Indicator which is used to check for minimum airflow is provided
with each complete respirator.
The user of this respirator must be fit tested before use to determine the model and
size facepiece that gives the correct seal to the face and proper visibility for the
intended use activities. Where required, a 40mm adapter assembly attaches to the
inlet port of the facepiece with a quarter turn and is secured with a spring loaded
retaining lock. Check valves for exhalation and inhalation are provided. Certain full
facepiece includes an integral nose cup with two inhalation valves. Some include
one or two voicemitter assemblies for voice communication. A net type head harness made of Kevlar®1 is available. Alternate head harnesses made of polyester or
EPDM/Rubber are also available. Certain facepieces are only approved for certain
protection classifications. See the APPROVALS AND CERTIFICATIONS section
of this instruction for details.
The SCOTT full facepieces are available in a variety of models and sizes. Users of
this respirator must correctly identify which model facepiece they are using and follow the appropriate DONNING PROCEDURES. This respirator is approved for use
with both the SCOTT AV-2000® and AV-3000® SureSeal™ Facepieces which both
require the use of either a facepiece adapter to connect the hose, or an AV-PAPR
Hose assembly which has an integral facepiece adapter. The AV-2000 facepiece
has a FOUR strap head harness and the AV-3000 SureSeal facepiece has a FIVE
strap head harness. This respirator is also approved for use with the SCOTT M98/
M120, Promask 40, and M95/M110 Facepieces which do not require the use of an
adapter. The M98/M120 and Promask 40 have a FIVE strap head harness, and the
M95/M110 Facepiece has a SIX strap head harness.
The corrugated breathing tube connects the outlet of the blower assembly to the
inlet of the facepiece. The breathing tube is available in long and short lengths to fit
different individuals. Choose a breathing tube length that is long enough to provide
a full range of motion without pulling on the facepiece, but not excessively long as
to present a hazard of snagging the hose while in use.

The blower assembly contains an electric motor driving an air blower. The compartment for a battery pack is located in the lower part of the blower assembly with a
battery cap on a lanyard. The battery pack is available in two versions:
1. A one-time use Lithium-Sulfur Dioxide (LiSO2) battery. When properly stored,
the 6 volt Lithium-Sulfur Dioxide battery is capable of extended shelf life. The
LiSO2 battery is not rechargeable.
2. A reusable Nickel-Metal Hydride (NiMH) rechargeable battery. The rechargeable battery provides an economical power source for training purposes or for
regularly scheduled use.
Because the two batteries are different lengths, there are two different battery caps
used to retain the batteries in the battery compartment. Only the battery cap for the
battery to be used should be installed on the lanyard.
An ON/OFF power switch is located on the top front of the blower assembly. There
are two (2) threaded inlets on the front of the blower assembly for the attachment
of the filter elements. The SCOTT C420 Plus respirator utilizes two (2) filter elements. Each filter element is individually sealed. Two (2) new filter elements must be
installed prior to using the PAPR. (See DISPOSAL OF USED FILTER ELEMENTS
section of this instruction). The waist belt supports the blower assembly at the waist
and is fully adjustable.
Each C420 Plus PAPR is supplied with an Airflow Indicator which is used to check
the overall ability of the respirator to provide sufficient air flow to the facepiece and
to monitor battery life. The air flow must be checked before each use.
It is the responsibility of the manager of the respiratory protection program under
which this equipment is used to properly chose, identify, and maintain the respirator
equipment for the selected protection. Part numbers for the respirator components
used must appear on the approval label for the selected protection. See the APPROVALS AND CERTIFICATIONS section of this instruction.

P/N 595130-01 Rev. D 9/10
THEORY OF OPERATION
The SCOTT C420 Plus respirator is a Powered Air Purifying Respirator (PAPR).
The user of the respirator breathes ambient air after the air has passed through a
pair of filter elements. The filter elements may include a mechanical filter to trap
airborne particulates or a sorbent bed of impregnated activated carbon to trap
and/or neutralize various gases and vapors. Filtration elements must be selected
specifically to suit the hazardous atmosphere application.
The full facepiece is intended to seal against the user’s face and allows the user to
breathe the air drawn through the filter elements. An inhalation check valve prevents
exhaled air from entering the blower assembly. The exhalation valves allow the exhaled breath to exit the facepiece into the surrounding atmosphere. The inhalation
and exhalation valves are integral to the facepiece or facepiece adapter.
The blower assembly assists breathing by drawing air through the filter elements
and delivering the purified air through the breathing tube to the facepiece. When the
blower assembly is used with the blower switch ON, the positive pressure inside the
facepiece affords the greatest level of protection to the user from the contaminants
in the atmosphere.
To maintain this level of protection:
1. The user must be properly fit tested to the tight fitting respirator facepiece
before use.
2. The blower must be tested with the Airflow Indicator with filtration elements
installed both prior to use and at prescribed intervals during use to monitor
the battery life and filter element efficiency.
3. The blower must always be used with the power switch ON when the respirator is used in a contaminated atmosphere.

FACEPIECE FITTING AND FIT TESTING
A respirator Quantitative Fit Test must be performed to ensure the correct respirator facepiece size
has been selected and assigned to the user. It is the responsibility of the Respiratory Protection
Program Manager or Safety Coordinator to assist the user in selecting the correct respirator size
relative to the user’s facial features and dimensions. Fit Testing must be performed with any approved SCOTT accessories that will be used with the respirator installed, such as a communications
device installed on the facepiece.
The size and style facepiece must be selected based on the user’s measured face size. Refer to
NIOSH Procedure No. TEB-CBRN-APR-STP-0552, DETERMINATION OF LABORATORY RESPIRATOR PROTECTION LEVEL (LRPL) VALUES FOR CBRN TIGHT-FITTING POWERED AIRPURIFYING RESPIRATOR (PAPR), STANDARD TESTING PROCEDURE for guidance on CBRN
respirator facepiece size selection.
Respirator fit tests are explained fully in the American National Standard Practices for Respiratory
Protection, ANSI Z88.10-2001 which is published by the American National Standards Institute
(ANSI), 11 West 42nd Street, New York, New York, 10036, and in the Occupational Safety and Health
Standards, OSHA 29 CFR 1910.134 Appendix A, which is published by the Occupational Safety and
Health Administration (OSHA), 200 Constitution Avenue, NW, Washington DC, 20210.
Quantitative Fit Testing per OSHA Standard 29 CFR Part 1910.134 Appendix A, or ANSI Standard
Z88.10-2001 requires testing in the negative pressure mode using equipment such as a Portacount®1
Respirator Fit Tester. The Quantitative Fit Test may be conducted with the facepiece configured as
a C420 Plus PAPR with the blower OFF or, alternatively, may be configured as a Full Facepiece Air

Test subjects must be in good health at the time of the fit testing. Smoking or eating less than 30
minutes prior to the test is prohibited. Any and all conditions that might interfere with a good face to
facepiece seal must be addressed and corrected before performing the fit testing. Refer to the list
of conditions in the DONNING PROCEDURES section of this instruction.
To verify the fit factor of the respirator, testing must incorporate an exercise regimen of normal daily
activities. SCOTT requires the following set of fit test exercises, which are based on OSHA Standard
29 CFR Part 1910.134 Appendix A, and ANSI Z88.10-2001 with modifications. Exercises are to be
performed each for 60 seconds (except as noted) in a standing position during the test:
•
Normal Breathing
•
Deep breathing
•
Turning head side to side
•
Moving head up and down (look up/look down)
•
Talking (read the Rainbow Passage)
•Grimace (15 seconds)
•Bending Over (touch toes) / Reach up (toward the ceiling)
•
Normal Breathing (repeat)
Fit test exercises must be performed carefully as if the respirator was being used in a hazardous
atmosphere. DO NOT bump the facepiece, filter, or adapter into the body through exaggerated motions. DO NOT talk except when directed to by the test administrator.
If the respirator user passes a NEGATIVE PRESSURE LEAK TEST but DOES NOT pass a respirator
Quantitative Fit Test, try the next nearest size, larger or smaller and repeat the NEGATIVE PRESSURE LEAK TEST and the Quantitative Fit Test. If testing an AV-2000®, AV-3000®, Scott-O-Vista®
and Weld-O-Vista™ full facepiece, and leakage is still detected, either per these user instructions or
the OSHA fit testing process, the use of Mask Seal Kit P/N 805655-01 may be required to attain a
proper fit. Refer to the INSTALLATION AND USE INSTRUCTIONS, SCOTT P/N 89462-01, included
with the Mask Seal Kit. After installing the Mask Seal Kit, repeat the fit testing process to confirm a
proper fit. If leakage is still detected, do not use the respirator.
Once the proper size is selected and assigned to the user following successful Portacount Respirator
Fit Tester testing to achieve minimum Fit Factors required, the respirator user must perform and pass
a NEGATIVE PRESSURE LEAK TEST every time the facepiece is donned to ensure proper fit before
using the respirator in a hazardous atmosphere. During NEGATIVE PRESSURE LEAK TESTING, any
facepiece leakage that is detected from other than the face to facepiece seal may indicate damaged
or defective equipment. Remove the defective equipment from service and tag for repair by authorized
personnel. Repeat the testing with equipment known to be operating properly.
IF A SATISFACTORY NEGATIVE PRESSURE LEAK TEST CANNOT BE PERFORMED, DO NOT
USE THE RESPIRATOR OR ENTER THE HAZARDOUS ATMOSPHERE.
The facepiece alone does not provide any protection against a hazardous atmosphere without the
use of the complete C420 Plus PAPR with the proper filtration media attached.
A respirator Quantitative Fit Test must be routinely carried out as outlined above for each user of this
respirator to determine or confirm the amount of protection that the respirator provides. Periodically
repeating the fit testing is required to identify any physical changes of the user (such as those listed
in the DONNING PROCEDURES) which could affect the fit of the facepiece.

PREPARATION FOR USE
The SCOTT C420 Plus respirator may be used with a variety of SCOTT full facepieces. The essential operation of all full facepieces is the same, but certain features
are applied differently depending the style of full facepiece. Inspect all components
prior to use. If any damage or discrepancies are found, remove the equipment from
service and tag for repair by authorized personnel.
There are two basic styles: WITH ADAPTER and WITHOUT ADAPTER. During
facepiece fitting and training, become thoroughly familiar with the facepiece with
which you are fitted.
FACEPIECES WITH ADAPTER
SCOTT full facepieces such as the AV-2000® or AV-3000®, the Scott-O-Vista®, and
Weld-O-Vista™ require the use of either a 40mm adapter (SCOTT P/N 805059-01)
or the AV-PAPR Hose assembly (SCOTT P/N 200829-30 or -36) which is a hose
with an integral adapter. Install on the respirator facepiece as follows:
1. Verify that the seal on the back of the facepiece adapter is in good condition.
2. On P/N 805059-01, verify the gasket in the 40mm connector is present and in
good condition.
3. On P/N 200829-30 or -36, verify the gasket in the Breathing Tube connector is
present and in good condition.

Page 35 of 48
P/N 595130-01 Rev. D 9/10
USE OF THE C420 Plus RESPIRATOR
1. The C420 Plus respirator must be properly prepared for use, properly donned
and negative LEAK tested in an area known to be free of contamination before
it can be used.
2. The selector switch must be in the ON position for use.
3. Use of the respirator must be in strict accordance with the limitations contained
in the LIMITATIONS ON USE section of this instruction and in compliance with
the written respiratory protection program and recognized respiratory standards,
i.e.: OSHA 29 CFR 1910.134.
4. Before entry into a contaminated area, the maximum safe duration of use must
be estimated. The maximum safe duration of use depends primarily on:
a) The amount and type of contamination in the air and the capacity of the
filter elements to absorb or neutralize that contaminant.
b) The amount of airborne particles (dust) in the atmosphere.
c) The charge contained in the battery.
d) The physiological limits of the respirator user.
The employer shall predetermine the maximum expected filter element life based
on a determination of the amount of contaminant in the atmosphere and the
capacity of the filter elements together with the expected air flow through the
filter elements. An average air flow of approximately two cubic foot per minute
(CFM) will flow through each filter element during prolonged use. In determining
maximum time of use, consideration must be given to the physiological limitations
of the user to remain in a contaminated area with the facepiece continuously
sealed to his/her face.
5. After four (4) hours of continuous use, the user must leave the contaminated
area, decontaminate if required, and check the airflow with the Airflow Indicator
(See IN USE FLOW TEST section of this instruction). Thereafter, the air flow
must be checked at least every two (2) hours of use to monitor battery life and
filter efficiency.
NOTE
DO NOT PERMIT THE BATTERY TO COMPLETELY DISCHARGE DURING USE.
ALWAYS CHECK THE BATTERY PERFORMANCE WITH THE AIRFLOW INDICATOR AND CHANGE OUT THE BATTERY IMMEDIATELY IF THE AIRFLOW HAS
DROPPED BELOW THE MINIMUM LEVEL DUE TO A LOW BATTERY.
6. If, during use, the air flow from the blower assembly should noticeably decrease
or stop completely, or if inhalation should become difficult, immediately leave
the contaminated area. Decontaminate, if required, and check the respirator.
7. If the airborne contaminant is detected by odor, taste, eye irritation, or if any
discomfort is felt during respirator use, immediately leave the contaminated
area. Decontaminate, if required, and check the respirator.
8. If the battery compartment should become hot to touch immediately turn the
power switch to OFF position. Do not remove the facepiece, but continue to
breathe through the respirator and immediately leave the contaminated area.
Decontaminate, if required, and check the respirator.

– a decrease in air flow from the blower assembly,
– a difficulty with inhaling,
– the expiration of time the filter element is expected to be useful in removing
airborne contaminants,
– or, after continued use, has exceeded the recommended time period of continued use,
an Air Flow Test must be performed on the respirator before reentry to the contaminated area. Perform the Air Flow Test as follows:
1. The user must leave the area requiring respiratory protection and be in an area
free from contaminants.
2. The user must be decontaminated, if required, at least to the extent that the
breathing tube can be disconnected from the blower assembly.
3. Airflow Indicator (805374-01) must be installed as shown in FIGURE 7 of this
instruction and the blower assembly air flow measured as stated in step 4 of
the REGULAR OPERATIONAL INSPECTION section of this instruction.

battery compartment becomes hot to the touch, immediately leave the area requiring respiratory protection, turn the power switch to the OFF position and determine
the cause of the problem.
If, for any reason, it becomes impossible to inhale through the respirator during use,
the user may have to disconnect the facepiece from the breathing tube or remove
the facepiece. THIS WILL TERMINATE RESPIRATORY PROTECTION AND THE
USER WILL BE BREATHING THE ATMOSPHERE THE RESPIRATOR WAS INTENDED TO PROTECT AGAINST.
To remove the breathing tube from the facepiece:
• On facepieces which DO NOT require an adapter, unthread the breathing tube
from the facepiece.
• On facepieces which DO require an adapter, pull the locking mechanism away
from the facepiece and rotate the adapter 1/4 turn clockwise (viewed from inside
of facepiece) and remove the adapter from the facepiece.
After removal of the breathing tube or adapter or removal of the facepiece, the user
must leave the contaminated atmosphere immediately. The respirator must be removed from service and tagged for repair.
Do not allow the blower assembly to be placed under water during use as water
will be drawn into the filter elements. If accidental immersion occurs during use,
leave the area requiring respiratory protection, turn power switch to the OFF position, remove the respirator from service and tag for inspection and/or repair. If it
becomes impossible to inhale through the filter elements after accidental immersion,
