Purpose
The Ericson UV-C Perma-Kleen Cart (PK-CART) system has
been designed to offer direct disinfection exposure to surface
areas. The system design allows for microbial disinfection
control.
The Ericson UV-C Perma-Kleen Cart (PK-CART) system was
developed as a cleaning device utilizing Ultraviolet Light (UV)
for direct exposure disinfection. The system can disinfect 360
degrees from the system center.
Contents
This manual will serve as your reference guide for
installation, operation, and service of your UV-C Perma-Kleen
Cart (PK-CART). Reference to all parts, warranty, and support
are included.
This manual covers the system/equipment/products listed
below:
• Ericson Part #: UVC-PK-CART-ULTRA
Safety Observation:
It is required for the person(s) responsible for the installation of this equipment, operators of this equipment, and operation
personnel managers to review and understand this manual.
USE OF LISTED SYSTEM / EQUIPMENT MUST COMPLY WITH INSTRUCTIONS AND SAFETY REQUIREMENTS.

Safety
1. You should never look directly at a UV lamp in operation without wearing
approved safety glasses. Safety glasses should be made of any material
other than Quartz or Teflon.
2. The space should be vacant and closed prior to PKCART operation
3. Never command the system on when the treatment space is occupied
PK-CART SAFE OPERATION
Disposal of Mercury Added Lamps
Germicidal ultraviolet lamps, like standard fluorescent lamps
contain small amounts of mercury. Mercury added lamps
should not be placed in the trash. Dispose of properly. For
further information regarding the disposal and recycling
of lamps containing mercury, along with Federal and State
requirements visit LampRecycle.org.
Safety Guidelines
Long term exposure to ultraviolet light is dangerous. UV-C
can produce eye injuries and skin irritation similar to a sun
burn over prolonged exposure. These effects are considered
transient. UV-C may also be carcinogenic but since it has
very limited penetrating ability it is unlikely to cause damage
to anything besides the outer layer of skin or other exposed
surfaces.
The Ericson PK-CART is designed for zero user exposure to
UV-C; however, we will review safety factors regarding UV-C
for better knowledge and understanding.
Protective Clothing and Eyewear
It is not recommended that any personnel be subject to
direct UV-C exposure. In the event such exposure is probable,
personnel should wear PPE providing full coverage of
exposed skin and appropriate eye protection.
UV-C safety glasses designed to filter UV-C and those of the
wrap-around type are recommended. Safety glasses should
be made of any material other than Quartz or Teflon.
OSHA Guidelines for Ultraviolet Exposure
OSHA provides technical guidance regarding protecting
employees from ultraviolet light with respect to laser hazards
only.
OSHA has two standards that cover employee exposure
to radiation: Nonionizing Radiation (29 CFR 1910.97) and
Ionizing Radiation (29 CFR 1910.1096). You may access a
copy of the OSHA radiation standards from their website at
http://www.osha.gov.
The non-ionizing radiation standard only covers the radio
frequency region, including microwaves. The ionizing
radiation standard covers alpha, beta, gamma, and X-rays;
neutrons; high-speed electrons and protons; and other
atomic particles; but does not include sound or radio waves,
or visible, infrared, or ultraviolet light. Therefore, there are
no OSHA-mandated employee exposure limits to ultraviolet
radiation.

The Ericson PK-CART is designed for maximum disinfection through the
shortest exposure time. More UV-C wattage allows shorter exposure times
to surfaces. Exposure times vary based on furthest distance from the UV-C
source. The system design provides the optimum in:
• UV dosage output to footprint served
• Rugged design build
• Ease of use controls
• User safety protection
• INDUSTRIAL STRENGTH FRAME AND STRUCTURE
• CORROSION PROOF CONSTRUCTION
• 6” INDUSTRIAL CASTERS
• HIGH OUTPUT PRE-HEAT LAMPS FOR LONG RUN TIME LENGTH
• PIR SENSOR DETECTION SAFETY SHUTOFF
• INDIVIDUAL LAMP FAILURE INDICATOR LED’S
• EMERGENCY STOP BUTTON
• BUILT TO IP56 WATER AND DUST STANDARDS
• SELECTABLE TARGET PATHOGEN

SYSTEM CARE

12
Q: What should I do if the unit will not turn on?
A: Verify there is power to the system
A: Verify the display is reads correctly
A: Verify the Emergency Stop is not engaged
Q: Why does the unit turn off when I enter the room?
A: Safety features turn off lamps based on detection by the PIR sensor.
Q: My system will turn on, but the lamps will not come on.
A: Verify the start cycle button is pressed
A: Inspect the lamp for age or physical failure
A: Contact Ericson Support for further information
Q: My system is running fine, how do I verify the lamp output is correct?
A: The system has a status screen at the end of the cycle
A: Use dosimeter cards in the space to verify UVC dosage.
Q: The touchscreen has presented a flashing “Service Machine” icon. What does this mean?
A: Every 8 running hours it is recommended that lamps be wiped down with isopropyl or rubbing alcohol. This will remove any debris that
may have accumulated on the lamp. Once cleaned, you can reset this message by pressing USER SETTINGS button followed by RESET
SERVICE LIGHT
Q: What is a PIR (Passive Infrared) Sensor?
A: PIR stands for Passive Infrared. These sensors are used extensively in occupancy sensors for lighting control and security products.
The PIR sensor detects human heat and movement. In the case of the PK-Cart, when it detects both human heat and movement it will
turn off the UVC Unit.
FREQUENTLY ASKED QUESTIONS

13
The below statements are listed as troubleshooting guidelines. Further information is available through Ericson support.
Q: Is UV-C disinfection strictly line of sight?
A: Yes, it needs to shine on the surface to disinfect. It will not go around objects or disinfect shadowed areas.
Q: Does UV-C light reflect off surfaces?
A: Yes, it reflects off many surfaces, but loses intensity dramatically if the surface is not highly polished like the Stainless-Steel center
installed on our unit.
Q: Is the UV-C light I can see under the door dangerous?
A: Zero exposure to people is imperative so block it or protect your eyes and skin (please note: 254nm UV-C wavelength is invisible, what
is seen is visible light)
Q: Does UV-C light go through glass or windows?
A: Standard window glass or poly carbonate provides sufficient protection from UVC rays.
Q: Can I use an ATP Meter with the PK-CART?
A: Yes. When used by properly trained personnel, it can be used to measure how clean a surface is.
Q: Can I use a response card with the PK-CART?
A: Yes, it can be used to indicate the correct dose has been applied to a surface
Q: What is the difference between bacteria and sporicidal modes?
A: Your PK-CART Ultra is equipped with two modes of operation, Bacterial and Sporicidal. It is important for the user to understand the
difference between the two. For sporicidal mode, the time function is doubled. Spores are the more difficult microorganism to target due
to the composition of the cell membrane. In order to be categorized as a spore a rigid protective layer on the cell membrane must exist.
Most common bacteria and viruses do not have this protective layer or have a layer of less rigid protection like lipids and are much easier
to deactivate using UV-C light. A common example of a sporicidal target is Clostridium difficile, or C. Diff.

The above listed treatment times are based on widely acceptable inactivation dose levels of 50,000 μWs/cm² (bactericidal) or 100,000 μWs/
cm² (sporicidal). It is offered as a reference point, in an empty space, using fresh lamps and does not account for objects physically blocking
UV-C ray transmission.
