This procedure must be followed in order
to ensure safe changeover of filters.

CAUTION

NOTE

Check to make sure that the wing nuts
are securely tightened. Excessive
compression of the filter gaskets can
cause leakage. Hand tighten only.

6.2

Filter Element Installation

(See Figure 1 SDF-4 Phantom View)

1. Slide new Torit-Built filter elements onto

each suspension yoke.

2. Hand tighten filters by turning wing nut

clockwise onto suspension yoke threads until
tightened securely.

6.3

Bag-Out Filter Element Removal

(See Figure 38 Bag-Out Assembly &

Figure 39 Bag-Out Filter Removal)

The bag-out option allows removal of filters
without exposure to atmosphere. Each filter is
removed in its own bag according to the
following procedure.

1. Attach the polyethylene bag to the bag-out

collar using the strap as shown in Figure 38
Bag-Out Assembly.

2. Reaching into the bag collar, using the bag

as a rubber glove, loosen the filter by
unscrewing the wing nut counterclockwise
by hand.

6.1

Filter Element Removal

1. Loosen filters, beginning with the top row,

by unscrewing the wing nuts
counterclockwise by hand (see Figure 1
SDF-4 Phantom View).

2. Move the filters to break the gasket seals

between the filter and the sealing surface.
Rotate the filter slowly 1/2 turn to dump any
loose dust off the top of the filter. Slide the
filter along the suspension yoke and out the
front of the access port.

3. Inspect the sealing surface to make sure that

the gasket sealing area is free of dust.

4. Check for an accumulation of dust in the

storage area. If cleaning is required, see
Section 6.4 Dust Removal/Dust Container.

Disconnect the SDF from all electrical
power sources and compressed air supply
and bleed off any residual pressure before
performing any service work.

CAUTION

NOTE

Do not drop or rap element on the
floor or other hard surface, as damage
to the filter element will occur, resulting
in leakage.

It is necessary to clean the dust off the
gasket sealing area to ensure a positive
seal of the filter gasket.
