CAUTION: Proper protective equipment and measures must be used at all times
during unit cleaning and maintenance. Check with your Safety Office to
assure the cleaning solutions, protective equipment (disposable hospital
gown, HEPA respirator, protective gloves) and protocols followed comply
with your facility’s and CDC guidelines.
CAUTION:
Disconnect the unit from the electrical power source before attempting
service. Do not work inside the IsoClean
®
UV with the UV light on. Proper
replacement of UV containment baffles, after maintenance, is mandatory to
maintain safe short-term and long-term UV exposure levels.
4.2. Cleaning the Unit
4.2.1. Periodic cleaning of the unit may be done with a mild disinfecting soap and water
solution. A 1% or 1/100 dilution of bleach is an optional disinfectant
5
.
4.2.2. Cleaning must be performed with the unit running. Wipe the exterior of the unit
with a damp sponge or cloth, paying particular attention to the prefilter intake
grille.
4.3. Prefilter Replacement
4.3.1. The prefilter should be replaced every 60 to 90 days. Regularly replacing the
prefilter will maximize the life of the HEPA filter.
The IsoClean
®
UV
comes standard with an anti-microbial pleated prefilter. It is
recommended that a pleated prefilter is used to insure that safe long-term
recommended exposure levels to UV are maintained.
4.3.2. Wipe the unit as described in Section 4.2.
4.3.3. Spray a mist of phenolic disinfectant such as “Amplyl” or “Lysol” into the air
intake grille.
4.3.4. Remove the two (2) thumb nuts from the face of the intake grille and pull the
grille out.
4.3.5. Insert gloved hand into a red plastic, medical waste disposal bag. Grasp the top
portion of the prefilter with bagged hand and gently pull outward. The airflow of
the unit will offer a resistance to pulling the prefilter out.
4.3.6. Turn the bag inside out over the prefilter then seal the bag for containment.
4.3.7. Install a new prefilter and close the grille up in the reverse order of removal.
