Page 3 …In Moist or Uneven Locations • Keep all tubing runs as short as Use a raised concrete pad or concrete possible. blocks to provide a solid, level foundation • Use the flare method for connecting for the outdoor unit. This prevents water tubing.
Page 4 CAUTI N CAUTION • Ventilate any enclosed areas when installing or testing the refrigeration system. eaked refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas. • Confirm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning stove, gas water heater, electric room heater or other heat source,...
Page 5 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 55 Precautions w hen operating the 3-w ay valve for piping installation Do not open the 3-way valve until the piping installation is completed. It is closed during shipment. During installation the side panel may warp if only the are nut is loosened and tightened with a torque wrench. As a result, always be sure to secure to the hexagonal part of the 3-way valve with a spanner, or other tool.
Page 56 Precautions for insulation installation Maximum temperature limit of gas or liquid piping exceeds 120 °C In high humidity environment, reinforce the insulation material for the refrigerant piping. Failure to do so may result in condensation on the surface of the insulation material. Use materials with good heat-resistant properties as the heat insulator for the pipes.

Page 119 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 120 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 121 6 ) Cooling Freez e Prev ention 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 122 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 123 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.

In this way, the setting switches that were located on earlier PCBs have been converted to EEPROM data. This remote controller is an outdoor unit maintenance tool that is used to make and change the EEPROM set- tings.
