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.

Page 101: How To Process Tubing
1-13. HOW TO PROCESS TUBING <Type E2> The liquid tubing side is connected by a flare nut, and the gas tubing side is connected by brazing. 1. 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 102 Caution Before Connecting Tubes Tightly (1) Apply a sealing cap or water-proof tape to prevent dust or water from entering the tubes before they are used. Apply refrigerant lubricant. (2) Be sure to apply refrigerant lubricant (ether oil) to the inside of the flare nut before making piping connections.
Page 103 3. Insulating the Refrigerant Tubing Two tubes arranged together Tubing Insulation Gas tubing Liquid tubing Thermal insulation must be applied to all units tubing, including distribution joint (field supply). * For gas tubing, the insulation material must be heat resistant to 120°C or above. For other tubing, it must be resistant to 120°C or above.

Page 141 1) Indoor Air Temperature Control By the control method, not only the thermostat is switched on and off, as explained section “1. Indoor Air Temperature Control ", but also the frequency of the compressor's inverter is controlled in accordance with T and fluctuations in indoor air temperature.
Page 142 4) Condensation Temperature Control (cooling) This system control is performed to limit the inverter frequency in order to restrict high pressure’s abnormal increase and high-load operating prevention in the cooling mode. In accordance with the temperature of the outdoor heat exchanger temperature sensors (C1, C2), such controls are performed as to halting the operations of the indoor unit, decreasing the inverter frequency and restricting its increase, etc.
Page 143 6) Cooling Freeze Prevention Control The following control is performed during cooling operations (including dry mode operation), in accordance with whichever of the indoor heat exchanger temperatures (E1 or E2) is lower. (See the chart below.) (a) Frequency will not be decreased less than 6 minutes after thermostat ON. (b) The threshold value is increased in accordance with the indoor load (differences of temperature).
Page 144 8) Defrosting Control This control function removes frost that has adhered to the outdoor heat exchanger during the heating operation. The control is performed to prevent the deterioration of the heating capabilities attributed to the adherence of frost, and to prevent the crack or crush of pipes attributed to the accretion of ice. The following control is performed in accordance with the ambient temperature and the outdoor heat exchanger temperature sensor (C1).
Page 145 Ending Defrosting Defrosting operations are ended when the following conditions are satisfied. • Ending defrosting conditions When the temperature of the outdoor heat exchanger temperature sensor (C1) is 10°C or higher. When the temperature of the outdoor heat exchanger temperature sensor (C1) is 6°C or higher for consecutive 60 seconds.
