OPTIONAL PARTS3-2 TC-17006-rev.13.2 Strainer Kit: MSF-NP63A and MSF-NP112AWhen connecting a wall mount to the VRF system, make sure to attach the strainer kit to the refrigerantpiping close to the indoor unit . This prevents solid particles from entering into the electronic expansion valveinside the unit.NOTES:1. Attach the strainer close to the indoor unit to facilitate replacement work.2. When the strainer is attached to an inside wall or roof space, provide a service access door formaintenance.3. When on-site piping has a buried joint such as a pipe elbow socket, provide a service access door tofacilitate checking for connecting parts.4. In order to prevent condensation, apply tape over the insulation material (accessory) and secure withcable bands.5. Refer to the "Installation Manual for Strainer Kit" for more details.Connect toChange-Over Boxor Multi-KitConnect toChange-Over Boxor Multi-KitLiquid Sideφ1/4 (φ6.35)Copper Pipe Connection Gas Sideφ1/2 (φ12.7)Copper Pipe Connectionφ1/4 (φ6.35) StrainerLiquid Side StrainerGas Side Strainerφ1/2 (φ12.7) StrainerPay attention tothe arrow direction.Pay attention tothe arrow direction.Field-SuppliedField-SuppliedField-SuppliedWall Mountφ1/4 (φ6.35)Copper Pipe ConnectionField-Suppliedφ1/2 (φ12.7)Copper Pipe ConnectionExample: MSF-NP63AUnit: inch (mm)No. Accessory Figure Qty.
