Initial Installation of HEPA Filters
and Carbon Filters
HEPA Filters (For Models 3970000, 3970002, 3970020,
3970022)
HEPA filters are shipped installed with the gasket on the
downstream side. The HEPA filters are leak checked at the
Labconco factory. A second leak check is recommended before
using the FilterMate and at least annually thereafter. Consult your
Safety Officer and Chapter 5 for the HEPA Filter Leak Test and
HEPA Filter Bag-In/Bag-Out Procedure. See Figures 3-3, 3-4 and
3-5 for HEPA filter location, HEPA filter gasket, filter clamp bolts,
rear bag cover and bag-in/bag-out flange. All seams upstream of
the HEPA filter are jacketed by negative pressure. This
intrinsically safe design ensures containment over time.
Carbon Filters (For Models 3970001, 3970021)
For carbon filter installation, first remove the rear filter cover,
secured by four Phillips head screws, on the back of the
FilterMate. See Figure 3-4 for location of the rear filter cover. See
Chapters 2 and 3 for a list of available carbon filters. All carbon
filters are installed with the gasket side downstream and opposite
the clamp bolts. Install the correct carbon filter for the application
and tighten the clamp bolts to compress the gasket 50%. See
Figures 3-3, 3-4 and 3-5 for carbon filter installation, similar to
HEPA filter installation.
Combination HEPA/Carbon (For Models 3970003, 3970023)
For combination HEPA/Carbon, the HEPA is installed first with
the gasket on the downstream side per Figure 3-5. The carbon
filter is installed second in the perforated plenum exhaust cover.
a. The perforated plenum exhaust cover is simply
removed via four hole plugs and four captive Phillips
head screws.
b. Next loosen the two clamps that will support the carbon
filter using a wrench.
c. Insert the carbon filter with the gasket against the white
painted FilterMate main housing.
d. Tighten the clamps to compress the gasket 50%.
