Indoor Unit Connection Kits

These fan coil connection kits are pre-configured combination packages of flare tube kits, couplings, or reducers to connect the liquid and suction lines of fan coils with flare connections and large horizontal outside air units to the piping system.Toensure equipment compatibility, the pre-flared kits are designed to utilize the factory Flare Nut provided with the original equipment.

The copper flare tube provided with the fitting is annealed (O60) C12200 copper tube and conforms to JIS B 8607 Class 2 dimensional requirements. The copper flared tube allowable working pressure is equal to the annealed copper tube rating by tube size per ASME B31.5.

The Coupling is ETL listed for U.S. and Canada with an allowable working pressure of 1167 PSIG per UL-207. The fitting is intended for use with C12200 Type L copper tube conforming to ASTM B280. All tempers of copper tube may be used(O60, H55, H58). The fitting may also be connected to C19400 copper alloy.

Specialty tube support inserts may be supplied with the kit for proper fit onto certain fan coil connecting tubing.Refer to RCS installation instructions for details prior to installing these fittings.
