Repair

Follow pressure relief procedure when you stop spraying or dispensing; and before cleaning, checking, servicing, or transporting equipment.

NOTICE

Be sure to label all fluid parts “resin” or hardener” when disassembling them. Doing so prevents inter- changing resin and hardener parts during reassem- bly and prevents contamination of the materials and fluid path through the equipment.

Color-coded chemically resistant tape may be used to label the parts. Use blue for resin and green for hardener.

Cartridge Assemblies

1.Follow Pressure Relief Procedure, page 12.

2.Use a wrench to remove the cartridge assemblies

(2) from the manifold.

3.Use a 90° allen wrench to pop the seat (2e) and seal (2f) out of the housing, or tap them out from the “A” and “B” inlet side.

NOTE: Seat retainer seal (2f) normally splits into two pieces when it is fully torqued into the housing. The lip is meant to retain the seat, spring, and ball during assem- bly. The seat retainer seal (2f) must always be replaced once it is disassembled.

4.Use a soft bristle brush to clean the manifold pas- sageways.

6.Inspect parts for damage and replace as necessary.

7.Assemble parts in reverse order from steps above. Press the assembly against a flat clean surface until seal (2f) snaps into place on the end of housing (2a). The seal (2f) will hold the spring (2c), ball (2d), seat (2e), and o-ring (2b) in place during assembly.

8.Apply lubricant to o-ring (2b) and end seal (2f).

9.Apply anaerobic sealant to external threads of car- tridge.

10.Install cartridge assemblies in manifold and torque to 125 ft-lbs (170 N•m).

NOTE: The high torque crushes the seal (2f) for a reliable seal up to 7250 psi (50 MPa, 500 bar).
