3.0 Installation
After completing the entire pre-operational inspection (Section 1.3), please refer to Sections 3.1 - 3.4 to
complete the following installation steps:
(1) Unpack the machine and place it in the designated operation position.
(2) Connect the electrical connection and check whether the machine rotates normally.
(3) Filling and installation of the filter module.
(4) Install the particulate filter.
(5) Switch on the machine.
(6) Inspect after switching on. (Refer to Section 3.4)
3.1 Installation location selection
Refer to requirements for the space reserved for installation in Section 1.5 of this manual.
3.2 Molecular filtration module
Proper filling, installation and maintenance of the molecular filtration module are essential for the effective
operation of the machine. The molecular filter module of the machine is specially designed for
PURAFILfilter material. The filter material uses the appropriate filling shape and filter bed depth of the
PURAFILfilter module to maximize its filtering efficiency.
3.3 Particle filter
The selection and installation of an appropriate particulate filter is a necessary step for users to obtain the
most suitable air quality. Particle filters have different sizes and efficiencies, and changes in these
characteristics may affect the performance of the machine. The particle filter can be customized
according to specific application requirements.
Preliminary filter
Slide the filter into the machine along the track. Pay attention to the installation direction. The air flow first
passes through the thick white side.
Final filter
Slide the filter into the machine along the track.

5.0 Machine maintenance
5.1 Replacement of parts and filter materials
PURAFIL products are very durable. When PURAFIL machines' parts need to be replaced within the
normal service life of the machine, replacement parts can be ordered. Please contact PURAFIL or a
product sales provider authorized by PURAFIL.
Filter material consumption:
In order to maintain the proper performance level of the machine, the particulate filter and PURAFIL
molecular filter materials must be replaced regularly because of their limited service life.
5.2 Special preventive measures
Waste disposal
PURAFIL filter material is non-toxic, harmless and non combustible. PURAFIL filter material removes
gaseous pollutants by molecular adsorption, and the final product is unlikely to harm the environment.
Although special precautions are not usually required when disposing of waste filter materials,
government regulations may require specific disposal procedures if the waste filter materials are harmful
to the environment. PURAFIL filter materials should not be discarded in the dustbin in large quantity,
because the weight of the filter materials will make it difficult to clean the dustbin. If the pollutants
removed from your environment include heavy metals and pesticides, an independent toxicity laboratory
analysis may be required.
Inhalation
It is recommended to replace PURAFIL filter materials in a well ventilated work area, because during the
replacement process, the abrasion between the particles in the filter material will cause the fresh filter
material to generate dust. Workers should avoid direct inhalation of large amounts of filter dust as it can
cause sneezing. A dust mask for protection is recommended when replacing filter material in a closed or
airless space.
Water
Avoid exposing the PURAFIL filter material to water or precipitation as this will dissolve the
permanganate. PURAFIL filter material should be stored in a dry environment with a relative humidity of
less than 95%. If human skin is exposed to permanganate solution, it will cause temporary harmless
brown staining. The permanganate solution can be removed by washing the skin with a solution of water
and sodium bisulfite.
Eye exposure
If filter dust comes into contact with eyes, rinse the eyes thoroughly with water and seek medical
attention.
* Refer to Purafil material's safety data sheet for other information.
5.3 Removal of stains on the filter material
The following decontamination procedures are for reference only, and PURAFIL and any of its
subsidiaries, any of PURAFIL's sales and service providers or employees make no warranties or other
representations as to the efficiency or safety of this procedure. Removing stains can further damage
clothing or items or tools used to try to remove stains.
If the dust in PURAFIL filter material comes into contact with organic material, two dyeing problems may
occur:
1. Insoluble manganese dioxide (MnO2), characterized by a medium brown color, may be found in the
consumed filter material and can usually be removed by normal washing.
2. New (unused) PURAFIL filter material contains potassium permanganate (KMnO4). Potassium
permanganate is a strong oxidant that reacts with and discolors any organic material in contact with it.
The stains are brown-black and can be removed in water with a sodium bisulfite solution.
However, if the fiber has been damaged by permanganate, the damage may be more obvious if the stain
is removed.

Warnings:
The cleaning process should start with the use of a very low concentration solution, and the concentration
of the solution gradually increases as required until the stain is removed. Direct use of a strong solution
may cause additional damage to the fabric.
Note:
Use of sodium bisulfite will release sulfur dioxide (SO2) gas, so it must be used in a well ventilated area.
