LAF Vertical Laminar Flow Hood
User Manual

for the operator to wear PPE to protect themselves as much as the product.
Operation
1. To start-up the hood, the power cord first needs to be plugged into a dedicated 10A, 235V power source.
2. The power buon can now be pushed on, which is located on the control panel. The power buon will
illuminate green while running, and the running motor blower will be audible.
3. The Sensocon® pressure gauge mounted on the front of the control panel will begin showing readings. No
work should be done in the hood until the pressure reading stabilizes in the acceptable range.
4. The light buon needs to be pushed on before work can be done in the hood. The light buon will illuminate
blue while “on”.
5. Clean the interior surfaces of the work area. Detailed cleaning instructions can be found in the next section.
6. If the hood has been on and the air has been flowing for at least 15 minutes, work can commence in the clean
hood.
Cleaning
First and most importantly, you should use and follow your facility’s Standard Operating Procedure for primary
cleaning instructions. Our cleaning instructions should be supplemental and do not take preference.
Do not use steel wool or steel pads while cleaning stainless steel or acrylic. We highly recommend not using
bleach as it can ruin the finish on the stainless steel if not done properly. Periodic cleaning of the plastic surfaces
with an acrylic cleaner, available at all home supply or hardware stores, will minimize particle accumulation on
these surfaces.
The transparent acrylic sides of the work area are designed to provide optimal light in the work area. Many
chemicals have an adverse effect on acrylic plastics. Never use household glass cleaners. Never use griy soaps
or household cleansers such as Comet® or Ajax®. Acrylics are aacked by concentrated alcohols, strong solvents,
chlorinated hydrocarbons and many aromatic hydrocarbons. They are also adversely affected by ultraviolet light.
Acrylic is unaffected by most inorganic solvents, mineral and animal oils, low concentrations of alcohols,
paraffinic and olefinic hydrocarbons, amines, alkyl monohalides, esters containing more than ten carbon
atoms, alkalines, non-oxidizing acids, salt water, photographic solutions and chemicals, petroleum oils and
greases, household cleaning products and chemicals used in treating water. For cleaning: 50% Ethyl Alcohol,
70% Isopropyl Alcohol, or a 5% bleach solution can be used. Do not use 95% or 70% Ethyl Alcohol, 99% Methyl
Alcohol or Windex®.
To clean the outside of the hood, we recommend using low linting wipes saturated with a sporicidal disinfectant,
such as PeridoxRTU®, using unidirectional, overlapping strokes. Ensure that the prefilter located above the unit
does not become saturated with cleaner. We recommend not using any abrasive cleaners such as Comet or Ajax
as they can scratch the stainless steel and acrylic windows.
Since this LAF unit should only be used to work with non-hazardous materials, a “decontamination” procedure
does not need to be completed before cleaning the inside of the hood. A “disinfectant” procedure should be
completed to ensure the hood is sanitized before more compounding occurs. The hood should be on during the
cleaning procedure, which means the blower and pressure gauge will be operational. The alarm may need to
be silenced during cleaning, which can be done by pushing the red Alarm Silence buon located on the control
panel.
Germfree recommends using a cleaning pad saturated with sporicidal disinfectant, such as PeridoxRTU®, to
clean the inside of the hood with unidirectional, overlapping strokes. The inside of the hood should be mopped
twice, and the surface should be le wet aer the second pass for at least 3 minutes. Any equipment that stays in
the hood should be cleaned with low linting wipes saturated with a sporicidal disinfectant.
