Brush Head Assembly
1. Position the brush head assembly in front of the swing
assembly.
2. Align holes in the brush frame and swing assembly.
Install hardware, using the cap screw in the center hole
and carriage bolts in the remaining holes.
3. Align the brush head plate with the swing assembly plate
and tighten the hardware.
4. Assemble the spring-chain assembly/assemblies. Attach
the spring end(s) to the brush head upright. Then place
the chain in a slot on the swing plate upright. Figure 2
shows a spring-chain assembly installed on the unit.
5. Connect the transport chain, which is attached to brush
head upright, to the remaining slot on the swing plate
upright. Figure 3 shows a transport chain installed.
NOTE - Use the transport chain to take weight off the spring-
chain assembly/assemblies while transporting the unit
between job sites.
6. Attach 2, 3/4 inch hoses to brush head tubes. Then,
connect the top hose “T” to the filter base and the bottom
hose ”P” to the run port on the valve.
NOTE: CH units with manual valves should first move “T”
fitting to left side tubes as shown in figure 3. This
will provide enough hose length to make the proper
connection.
