Multi-Frame Heat Pump Unit Pipe Kit

These kits are braze-free alternative to the equipment manufacturer Outdoor Unit Multi Connection Pipe Kits. These outdoor pipe kits provide the necessary Y-Branch fittings, couplings, reducers, to field connect dual and triple frame VRF outdoor units to the refrigerant tubing system by means of permanent mechanical connection. Each kit is custom built to match the project system selection lay-out as provided by the customer.

The Y-branch, couplings, reducers, and silicone cold shrink sleeves are shipped loose for installation on to the field piping. Accessory tubing and outdoor unit connectors 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.

Refer to RCS installation instructions for details prior to installation.*The copper Y-Branch center fittings are not UL Listed component
