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 74: How To Process Tubing
1-11. 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 75: Ø6.35
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 76 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.

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 78 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.

3. Out Rear 4. 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 80 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 81 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. To prevent condensation Inter-unit Gas tube Liquid tube control wiring from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing.

Page 123 2) Maximum and Minimum Frequency Control The compressor's inverter frequency is controlled in accordance with the model and operation mode. The maximum and minimum frequencies for each model are shown in the chart below. * There are cases in which frequency is limited with other control functions depending on operational conditions, so operations are not always carried out in accordance with the maximum frequencies listed below.
Page 124 5) Heating High-Load Prevention Control The following control is performed in the heating mode in accordance with the indoor heat exchanger temperature max (E1, E2). (See the chart below.) (1) The operational frequency of the compressor is decreased when the temperature enters the "M" zone. The operation frequency is modified every 30 seconds while the temperature remains in this zone (the thermostat is switched off if it continues for 2 minutes).
Page 125 7) Discharge Temperature Control The following control is performed to prevent the discharge temperature from rising abnormally in order to protect the inverter compressor. In accordance with the temperature of the discharge sensor TD, such controls are performed as to limiting the increase of inverter frequency, decreasing it or halting operation of the compressor.
Page 126 Heating Mask Time This refers to the shortest time that heating operations must be performed without defrosting operations being executed. The mask time for this model is 25 minutes. Defrosting operations will not be commenced until the defrosting mask time has elapsed, even if frost adherence has been detected.
Page 127 12) Demand Control There are two styles of demand operations available as methods of restraining power consumption. (1) Demand via External Input Demand input from an external source is carried out from the outdoor unit EXCT (CN030) PCB or the outdoor unit's serial/parallel I/O (optional).
