  • Page 4: 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.

Connecting the Refrigerant Tubing Use of the Flaring Method Many of conventional split system air conditioners employ the flaring method to connect refrigerant tubes that run between indoor and outdoor units.
  • Page 49 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. Be sure to apply refrigerant lubricant (ether oil) to the Apply refrigerant lubricant. inside of the flare nut before making piping connections. This is effective for reducing gas leaks.

Out Bottom Flare Process Flare Process The ø25.4 gas main will not pass easily into the opening for coolant pipes in the pipe cover, so make sure you connect the ø25.4 pipe with the ø19.05 pipe outside of the outdoor unit. (2) Tightly connect the indoor-side refrigerant tubing Torque wrench extended from the wall with the outdoor-side tubing.
  • Page 51 In order to prevent damage to the flare caused by over-tightening of the flare nuts, use the table above as a guide when tightening. When tightening the flare nut on the liquid tube, use an adjustable wrench with a nominal handle length of 200 mm.
  • Page 52 4. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle.
