Clean Static Mixers
See FIG. 1 on page 8. Typically, two static mixer hous-
ings are connected to the mix manifold outlet (H). These
housings use plastic mix elements, available in a pack-
age of 25 (Part No. 248927).
To clean the housing and replace the mix element:
1. Relieve pressure, see page 12. Remove mixer
housings (J) from whip hose (K).
2. Place flats of mixer housing (J) in a grounded vise.
Push mix element (P) out of the inlet end.
3. If necessary, use a 1/2 in. drill bit to drill out old
material and the mix element from the inlet end,
down to the internal shoulder at the outlet end.
4. Use a brush to clean any debris in housing (J).
5. Insert new mix element, wide end first.
Clean “B” Side Screen
NOTE: The following instructions apply only when
using the strainer accessory for low viscosity fluids.
See Accessories on page 26.
1. Loosen swivels (19) and remove shutoff handle (21)
and valves (20). See F
IG. 3.
2. Remove “B” inlet union (19) from manifold block (1).
3. Pull “V” screen (17) and retainer o-ring (18) straight
up and out with a needle nose pliers.
4. Clean or replace screen (17).
5. Reinstall screen (17) and o-ring (18) with accessory
tool 15T630.
NOTE: The o-ring (18) is used as a retainer ring, not a
seal. It may be scratched or deformed from pushing the
screen (17) back in.
6. Install “B” inlet union (19) from manifold block (1).
Clean Mix Manifold Outlet
1. Remove outlet fitting (5) to expose “B” center injec-
tion tube (4).
2. Clean any build-up on, around, or inside the tube
(4).
3. Reinstall outlet fitting (5).
NOTICE
Never use a swivel union on the mixer inlets. The
union will compress the tube and make it impossible
to remove the mix element.
