IMPORTANT! Please Read Before Starting This air conditioning system meets strict safety and oper- ating 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.
Check of Density Limit 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.
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.
iv 3-2. Use R410A exclusive cylinder only. When charging with a refrigerant cylinder, use an electronic scale for charging refrigerant. In this case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change.
