Installation Instructions Frontseating Valves Factory Installation Step 1 Attach the valve using the mounting procedure that best suits the application. Clean the tubing to be brazed to the Parker frontseating valve. Step 2 Step 3 After brazing, Step 4 quench the joint with a wet rag to cool the joint and remove any flux residue. Flux the copper tubing and insert into the stub. Flux is not required if a low to zero-silver braze alloy is used. Braze the joint. Due to the extended copper stub the valve does not need to be immersed in water or otherwise cooled during brazing. Install a valve core (part #222034-4) and a valve cap (part #221014-4B) on the charge port. Field Installation Install the outdoor and indoor units per the manufacturer s recommendations. Route the copper lines between the units. Step 1 The tubing should Step 2 Wrap a wet rag Step 3 Flux the copper Step 4 After brazing be cut square, so it is round and free of burrs at the connecting ends. Clean the tubing to prevent contaminants from entering the system. around the copper stub before brazing. tubing and insert into the stub. (Flux is not required if a low to zero-silver braze alloy is used.) Braze the joint. quench the joint with a wet rag to cool the joint and remove any flux residue. Step 5 This is not a backseating valve. To open the valve remove the valve cap with an adjustable wrench. Insert a 3/16" or 5/16" hex wrench into the stem. Back out counterclockwise until the valve stem incurs resistance. Step 6 Replace the valve cap finger tight then tighten an additional 1/12 turn or 1/2 hex flat. A metal-to-metal seal is now complete. Complete normal factory recommended procedures. 116
Technical Information RB01 Series Ball Valves RB01 Series Ball Valves Parker s RB01 Ball Valves are used as service valves in split air conditioning and heat-pump systems or in commercial refrigeration applications. The valves isolate sections of a system for servicing and provide a means for charging refrigerant into a unit. Application Residential and commercial air conditioning and heat pumps Commercial refrigeration Base Product Part Number RB01 Full-flow design provides low-pressure drop for maximum system performance. One quarter-turn, low-torque actuation allows the valve to be open or closed providing simple and easy servicing. Use of a standard crescent wrench provides simple quarter-turn actuation. Copper-sweat connections provide basic ends for brazing and eliminate the need for flux, simplifying the installation process. Brass body and copper-connection tubes virtually eliminate corrosion-related problems. A unique copper-forming process is used to captivate the valve ball, seals, and spring, eliminating potential leak paths and providing consistent and superior sealing. Pad and post-mounting are available to provide additional support to the valve, if necessary. Multiple end-configurations are available, along with assemblies, to meet the unique needs of a unit. Agency Approvals UL recognized; File No: SA5188 Simple On/Off One quarter-turn, low-torque actuation allows the valve to be fully open or closed providing simple and easy servicing. Corrosion Resistant Brass body and copper connection tubes virtually eliminate corrosion related problems. Reliable A unique copper forming process is used to captivate the valve ball, seals and spring, eliminating potential leak paths and providing consistent and superior sealing. Value-Added Valves can also be supplied as fully tested subassemblies, complete with custom bent copper tubing and other required system components. This translates to fewer braze joints, simplified assembly, and a lower installed cost. Efficient Full-flow design provides lowpressure drop for maximum system performance Easy Installation Copper sweat connections simplify the installation process (eliminating the need for flux and flux-residue cleanup), saving time and money. Pad and post mounting is available if added support is needed. Service and 117

Technical Information RB8 Series Multi-Function Cooling-Only Flare Valves RB8 Series Multi-Function Cooling-Only Flare Valves Parker s RB8 Multi-Function Flare Valves are used as service valves in mini-split air conditioners. The valves isolate sections of a system for servicing and provide a means for charging refrigerant into a unit. The valve also holds a restrictor and screen to meter refrigerant and filter debris, increasing system efficiency. Application Mini-split air conditioners Base Product Part Number RB8 Inclusion of a restrictor into the valve provides precise refrigerant metering to increase efficiency. Noise and vibration through the unit are reduced by inclusion of the restrictor into the valve. Inclusion of a screen into the valve filters dirt and debris prior to entering the restrictor, maintaining full flow and enhancing performance. Captivated stem-design holds the stem within the valve to prevent it from releasing when the cap is removed or the unit is serviced, reducing the potential for injury. Combined functionality of valve, restrictor, and screen reduces component inventory (shut-off valve, field-access gage port, expansion device, filter screen or strainer, line-set connector, check valve, by-pass circuit, and capillary tubes) leading to a reduction in overall installed cost. Combined functionality of valve, restrictor, and screen also reduces space requirements within a unit and eliminates braze joints to reduce potential leaks paths. Patent-pending.
