04-396 Inverter-W_a-p50 ARGO 12/21/04 9:38 AM Page 2 IMPORTANT! Please Read Before Starting When Installing… This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently. …In a Room Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.
04-396 Inverter-W_a-p50 ARGO 12/21/04 9:38 AM Page 3 2. The standards for minimum room volume are as follows. Check of Density Limit The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its density will not exceed a set limit. The refrigerant (R410A), which is used in the air conditioner, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone layer.
04-396 Inverter-W_a-p50 ARGO 12/21/04 9:38 AM Page 4 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.” For tubes of φ19.05 or larger, use C1220 T-1/2H material or H material, and do not bend the tubes. ● Tubing size: Be sure to use the sizes indicated in the table below.
04-396 Inverter-W_a-p50 ARGO 12/21/04 9:38 AM 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. 2.
