2. The standards for minimum room volume are as follows. Check of Density Limit (1) No partition (shaded portion) The room in which the air conditioner is to be installed requires a design that in the event of refrig- erant gas leaking out, its density will not exceed a set limit. The refrigerant (R410A), which is used in the air condition- er, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone (2) When there is an effective

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 ø7/8" (ø22.22 mm) 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. ● Use a tube cutter when cutting the tubing, and be sure to remove any flash.

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. Existing tubing cannot be used (especially R22). Complet
