Precautions for Installation Using New Refrigerant 1.Care regarding tubing 1-1.Process tubing Material:Use C1220 phosphorous deoxidized copper specified in JIS H3300 “Copper and Copper Alloy Seamless Pipes and Tubes.” Tubing size:Be sure to use the sizes indicated in the table below. Use a tube cutter when cutting the tubing, and be sure to remove any flash.This also applies to distribution joints (optional).
Page 5 3-2.Use R410A exclusive cylinder only. Valve Single-outlet valve (with siphon tube) Liquid refrigerant should be recharged with the cylinder standing on end as shown. Liquid New refrigerant R410A cannot be used for earlier models 1.Compressor specifications are different. If recharging a R22 or R407C compressor with R410A, durability will significantly decrease since some of the materials used for compressor parts are different.

Design of Mini VRF SYSTEM 5. HOW TO PROCESS TUBING 5. HOW TO PROCESS TUBING Deburring 5-1. Connecting the Refrigerant Tubing After Before Use of the Flaring Method Many of conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units.In this method, the copper tubes are flared at each end and connected with flare nuts.
Page 49 Design of Mini VRF SYSTEM 5. HOW TO PROCESS TUBING Caution Before Connecting Tubes Tightly Apply a sealing cap or water-proof tape to prevent dust or water from entering the tubes before they are used. Apply refrigerant Be sure to apply refrigerant lubricant to the matching lubricant surfaces of the flare and union before connecting them together.
Page 50 Design of Mini VRF SYSTEM 5. HOW TO PROCESS TUBING 5-3. Insulating the Refrigerant Tubing Tubing Insulation Thermal insulation must be applied to all unit tubing, Two tubes arranged together including distribution joint (purchased separately). Liquid tubing Gas tubing * For gas tubing, the insulation material must be heat resistant to 248°F or above.
Page 51 Design of Mini VRF SYSTEM 5. HOW TO PROCESS TUBING 5-4. Taping the Tubes At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle. To prevent the condensation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing.
