Page 31: Assembling And Replacing The Hepa Filter
12.0 ASSEMBLING AND REPLACING THE HEPA FILTER A HEPA filter is designed for filtration of ultra-fine particles. A clogged HEPA filter will reduce the air flow thereby reducing the vacuum’s performance thus requiring replacement. The life of the HEPA filter depends greatly on the use of the vacuum cleaner system. The best indication of a saturated HEPA filter is a noticeable drop in the performance of the vacuum cleaner system. - Page 32 a. Shut off main air supply and open ball valve on the frame of the vacuum cleaner system to relieve the pressure in the air supply hoses. b. Once the pressure has been relieved close ball valve on the frame of the vacuum cleaner system c.
- Page 33 d. Gently remove the housing and place it on a flat surface. e. Place a poly liner around the now exposed HEPA filter. Carefully remove the HEPA filter from the back plate. Place the HEPA filter into the poly liner, gently twist the poly liner and then seal it with a tie wrap.
