Upper Manifold O-Ring Replacement
WARNING:
Relieve system fluid pressure and shut off system electrical power before
performing the following procedure. Failure to do so could result in personal injury.
Have the following on hand:
• replacement O-rings
•
petroleum jelly (do not use O-ring lube)
NOTE:
Inspect all O-rings and replace any that are damaged. Lubricate all O-rings with
petroleum jelly before assembly. The soft goods service kit listed in Parts includes all
O-rings used in the MEG gun, or they can be ordered separately.
Removal
See Figure 6.
1. Make sure all pressure is relieved and electrical power is removed from the system.
2. Remove the MEG II gun from the spray machine.
3.
Loosen the set screw (13) and the gun module nut (12). Carefully pull the gun
module (6) out of the gun.
4. Disconnect the gun wiring from the terminal block and fuse holder, if used.
5.
Unscrew the connector gland nut (8) from the connector body (9).
6.
Unscrew the connector body and manifold lock nut (10) from the upper manifold (3).
7.
Loosen the stop screw (14).
8.
Press on the back of the upper manifold to push it out of the lower manifold (11).
NOTE:
You can install the two larger O-rings (1) from the front or the back of the upper
manifold. If you install them from the back, you will have to pull the manifold wires all the
way out of the conduit and through the manifold lock nut and lower manifold.
9.
Slide the gun module nut off the upper manifold.
10.
Remove and discard the O-rings (1, 4, 5).
Installation
See Figure 6.
1.
Lubricate the new O-rings (1, 4, 5) with petroleum jelly and install them onto the
upper manifold (3).
2.
Slide the gun module nut (12) toward the front of the upper manifold until it hits the
manifold shoulder.
NOTE:
If you pulled the upper manifold wires out of the conduit and lower manifold,
thread the wires through the lower manifold (11), the manifold lock nut (10), and the
conduit (7) before you insert the upper manifold into the lower manifold.
