Page 6 Check of Density Limit U-200PZH2E8, U-250PZH2E8 The refrigerant (R32), which is used in the air conditioner, is a flammable refrigerant. So the requirements for installation space of appliance are determined according to the refrigerant charge amount [m ] used in the appliance. The minimum indoor floor space compared with the amount of refrigerant is roughly as follows: 45.0 40.0...
Page 7 Precautions for Installation Using New Refrigerant 1. Care regarding tubing (1) Process tubing Material: Use seamless phosphorous deoxidized copper tube for refrigeration. Wall thickness shall comply with the applicable legislation. For tubes of ø22.22 or larger, use the material of temper 1/2H or H (Hard copper tube). Do not bend the hard copper tube. For the renewal tubing size, refer to the Technical Data.
Page 8 Important Information Regarding The Refrigerant Used This product contains fluorinated greenhouse gases. Do not vent gases into the atmosphere. Refrigerant type: R32 value: 675 GWP = global warming potential Periodical inspections for refrigerant leaks may be required depending on European or local legislation. Please contact your local dealer for more information.

Page 62 6. Detection of ﬂ ammable refrigerants • Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. • A halide torch (or any other detector using a naked ﬂ ame) shall not be used. 7.
Page 63 9. Charging procedures • In addition to conventional charging procedures, the following requirements shall be followed. - Ensure that contamination of different refrigerants does not occur when using charging equipment. - Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. - Cylinders shall be kept upright.
Page 64 11. Labelling • Equipment shall be labelled stating that it has been de- commissioned and emptied of refrigerant. • The label shall be dated and signed. • Ensure that there are labels on the equipment stating the equipment contains ﬂ ammable refrigerant. 12.

2-12. Caution for Pump Down Pump down means refrigerant gas in the system is returned to the outdoor unit. Pump down is used when the unit is to be moved, or before servicing the refrigerant circuit. How to perform Pump-Down (Refrigerant recovery) properly (1) Stop operation of the unit (cooling, heating etc.).

T= (Indoor air temperature) - (Temperature set with the remote controller) In the body thermostat mode Indoor air temperature = (Body sensor) - (Shift temperature *) (setting at factory shipment) In the remote controller thermostat mode Indoor air temperature = (Remote controller sensor) * Shift Temperature...
Page 185 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 186 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 187 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 188 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 189 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.
Page 190 12) Silent mode It is avilable to select one of 3 levels of silent mode as listed in the table below. Outdoor maintenance remote controller: Item code “05” (1: Silent level 1, 2: Silent level 2, 3: Silent level 3) Attention: Due to decrease of operating noise level, the air conditioner's capacity can be reduced.
