Page 5: Check Of Density Limit
Check of Density Limit The standards for minimum room volume are as follows. (1) No partition (shaded portion) 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. -
