g. Insert each labeled crimp connector into its respective labeled 23-pin connector position (A, B, C, D,
etc.). Verify that each is firmly seated.
h. Pull the strain relief fitting back up the cable and screw it firmly into the base of the 23-pin connector
assembly.
i. Gather all the cables at the other end of the strain relief fitting into a bundle and tighten the two (2)
strain relief fitting screws until the cables are snugly captured.
j. Pull the shrink wrap tubing back up the cable and push it over the strain relief fitting until it meets the
base of the 23-pin connector.
k. Using a heat gun or other directional heat source, heat the shrink wrap tubing until it shrinks over the
23-pin connector assembly and cables.
l. Identify each wire on the site installed cables and label it (A, B, C, D, etc.) in accordance with the
labels on the 23-pin connector assembly wires. Assembling the connector is complete.
Caution: Overheating the shrink wrap tubing can result in damage to the tubing and the entire 23-pin
connector assembly.
8. Remove the service cover from the front of the wall mount by removing the four (4) captive screws.
9. Route the 23-pin connector assembly through the service cover and out the back of the wall mount.
Leave the 23-pin connector assembly and an excess of about 2 in. (51 mm) of cable at the service
opening.
10. Inspect the top of the housing assembly and verify that there is no debris on the gasket area. If there is,
wipe this surface clean with a cloth.
11. Lift the top of the housing assembly up to the wall mount’s pressurized housing mounting flange. Align the
two (2) sets of four (4) mounting holes so that the relief valve is located closest to the service opening
(slightly off to the right side, facing forward). Press firmly.
Note: Failure to correctly orient the Housing can cause difficulty in future servicing.
12. Insert the four (4) provided ¼-20 x 5/8 in. (16 mm) long hex head screws through the provided ¼ in.
(6 mm) lockwashers and into the mounting holes. Tighten all screws securely with a 5/8 in. (16 mm)
socket wrench. Carefully release the housing assembly and verify that the mount can support the weight
load.
13. With the housing assembly attached to the wall mount, locate the 23-pin connector assembly in the
service opening.
14. Insert the 23-pin connector assembly into the mating 23-pin connector on the top of the housing
assembly. Turn it until it drops down into the keyed slot and twist it clockwise ¼ turn to lock it.
15. Connect the previously labeled site wiring to their corresponding cable assembly labeled wires using
standard wiring practices such as wire nuts. If using conduit, route all cables through the liquid-tight
fitting/conduit, previously installed in the access hole, before connecting to the site wiring.
16. At the lower side, remove the cap from the fill valve. Using a small-tipped instrument, press the internal
pin down to release any residual gas from the housing.
17. Loosen the eight (8) captive screws from the trim ring/lower dome assembly and lower it. Allow the lower
dome to hang from its safety cord during the remaining assembly.
