Fig. 9 — Coil Connection Data 15 100% Coil Circuiting Applications: 084 Units 1. Piping — Refer to Fig. 9 and 21 for field piping details for 100% coil circuiting. Note that tubes 16 and 20 require a cut on the longer leg of the tubes. Two 7/8-in. OD tubes, approximately 3 in. (72.6 mm) long, must be cut from the remaining tubes (22 or 23) and brazed between the tees (item 9) and coil header stubs. The remaining tubes are not used in this application and may be discarded. 2. Install Fan Cycle Pressure Switches and Clamps — Braze 2 valve core bodies to designated hole locations on tubes 20 and 24. Insert valve cores into valve core bodies by threading into place and tightening to 1 5 to 3 in.-lb (169.5 to 339 mN-m) Install FCPS1 and FCPS2 at designated locations on tubes 20 and 24. Cut the 3/8-in. field-supplied FCPS conduit at a desired length to fit between each FCPS location and the junction box on the unit. See Fig. 11 for typical conduit installation. Feed FCPS wires through each conduit and secure at the switch by utilizing each conduit connector. See Fig. 13. Secure the conduit at the junction box with 3/8-in. field-supplied conduit connectors.
