Heat Recovery ODU Connection Kits

These kits provide the necessary couplings and reducers to connect VRF outdoor condensing unit to the refrigerant piping system. Each kit is custom built to match the project system selection lay-out as provided by the customer. The couplings, reducers, and silicone cold shrink sleeves are shipped loose for field installation on to the condensing unit connecting piping. Adequate tool clearance must be confirmed prior to installation. Accessory tubing and Multi-Frame Y-Branch pipe kits are NOT included and must be installed separately.

All RCS fittings installed outdoors, at the outdoor units, on insulated piping located outdoors, in wet/humid environments, or wherever the thermal insulation cannot be installed per the insulation manufacturer’s instructions, must be protected from possible corrosion via the use of cold shrink, heat shrink, or other suitable impervious protective cover.

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