Mixer Tubes

See drawing 22020

Mixer tubes will only require replacement if partial or full gellation/sedimentation has
occurred in the injection head. They cannot be repaired and must be replaced.


To replace, remove mixer shroud from head. (If MPG option is fitted, signal pipes

must be removed first.) Remove mixer tube from shroud. Lightly grease new mixer
tube/shroud threads with silicon grease, ensure O ring is in position and replace in
mixer shroud.


Re-attach to mixer head and reconnect MPG pipes if applicable. (Blue pipe nearest to
mixer tube)




Resin and Catalyst Pipework

See drawing 22022/22028

If air is being drawn into the system, check integrity of all joints and connections
shown.


Joints should be tight and sealed correctly using a proprietary thread sealant. Do not

use sealant on cone and seat type joints.
