User Servicing Instructions; Filter Replacement - MANN+HUMMEL TRI-KLEEN 500 UV BR Instruction Manual

Note: If the room air filtration units are being used to create and maintain a negative or positive pressure condition, the
pressure differential (between the room which has the unit and the environment outside the room) should be
monitored with a calibrated instrument according to the requirements.

USER SERVICING INSTRUCTIONS

TRI-KLEEN portable air filtration units are designed to be low maintenance devices and basic maintenance should be
performed as follows:
•
Filters should be changed as needed based on the status indicated on the LCD touch screen. Follow the FILTER
CHANGE PROCEDURE as described in this manual. Filters can be changed earlier, if desired, to maintain a
minimum required flow rate.
•
The unit should be cleaned with a damp cloth, water-based cleaner/sanitizer, or a germicidal or antimicrobial
cleaning agent as needed. Do not use harsh chemicals, solvents or detergents to clean the unit.
Note: Mann+Hummel recommends that the HEPA filter be changed after 12 months, regardless of how little the unit
may have been used, as a precautionary measure as some materials in the filter's construction can be affected over
time.
Note: The HEPA filter/UV lamp assembly in UV models is supplied as a unit and must be replaced as such. The UV lamps
have a rated service life of approximately 8,000 h, provided they are not turned "ON" and "OFF" several times a day.
The UV lamps are permanently mounted inside the HEPA filter frame and they are not replaceable. Mann+Hummel
recommends replacing the HEPA filter/UV lamp assembly at least every 12 months.
Warning: Keep electrical components dry as their exposure to liquids poses a safety hazard and can damage
components.

FILTER REPLACEMENT

System airflow reduction is generally the result of filter loading, blockage of the unit's inlet or outlet, or use of excessive
lengths of flex duct that is connected to the outlet.
The size and concentration of airborne contaminants, temperature and humidity conditions, and duration of use
determine how often filters need replacement.
If a carbon filter is being used instead of the pleated pre-filter, the method of determining when to replace the activated
carbon filter is somewhat subjective when it comes to reducing odors. As the odor, vapor, and/or gas filtration capacity
Note: Personnel responsible for changing filters, servicing units, or relocating units
within the facility are urged to wear the proper personal protective equipment (PPEs)
(mask, gloves, glasses and face shield) and follow safe work practices in accordance
with federal, state, provincial, local, and employer regulations. Mann+Hummel cannot
recommend the type of PPE required as that will need to be determined by safety/risk
assessment personnel based on various risk factors, including the type of particulates
being captured by the air filtration device and the surrounding environment where the
units are being used, transported, or serviced.
Note: Filters being replaced must be disposed of in accordance with federal, state,
municipal, local, and facility regulations.
