Page 2: Warnings On Refrigerant Leakage
WARNINGS ON REFRIGERANT LEAKAGE Refrigerant density limit The room in which the air conditioner is to be installed should be designed or chosen such that in the event of a refrigerant gas leak the density of gas should not exceed a set limit. The refrigerant R-410A, which is used in the air conditioner product, is intrinsically safe without the toxicity or combustibility of ammonia. - Page 3 Note 3: The minimum indoor floor area compared with the amount of refrigerant is roughly as follows (when the Range below the ceiling is 2.7 m high): density limit of 0.3 kg/m (countermeasures not needed) Range above the density limit of 0.3 kg/m (countermeasures needed...

Page 5: Safety Caution
SAFETY CAUTION Important safety information is displayed on the product and in this Installation Manual. Please ensure this is read thoroughly and keep for future reference. Before any repairs or maintenance is carried out an assessment of the potential risks must be undertaken, and appropriate measures taken to ensure the safety of all personnel. - Page 6 WARNING Check earth wires Before troubleshooting or repair work, check the earth wire is connected to the earth terminals of the unit, otherwise electric shock could occur. • If the earth is not correctly connected, turn off the system and contact an electrical engineer.
- Page 7 WARNING Insulation check Ensure that the electrical insulation is intact before energising. • After the installation is complete, carry out an insulation resistance test (using a 500 V DC Megger), to check the resistance is 2 MΩ or more between each electrically charged section (phase) and the metal chassis (Earth).
- Page 8 New refrigerant (R-410A) This air conditioner features a new HFC type refrigerant (R-410A) which does not deplete the ozone layer. 1. Safety caution concerned with new refrigerant The pressure of R-410A is 1.6 times higher than that of former refrigerant R-22. The refrigerating oil has also been changed.

Page 9: Selecting A Location For Installation
1. SELECTING A LOCATION FOR INSTALLATION WARNING The installation of the air conditioning unit must be positioned in a location that can sufficiently support its weight and give protection against adverse environmental conditions. Failure to do so may result in unit damage and possible human injury. All cassette type and concealed duct air conditioner units must be installed at a minimum height of 2.5m or more from the floor. - Page 10 Combination of outdoor unit Cooling Only Model No. of Model name Inverter 5HP Used Inverter 6HP Used Inverter 8HP Used Inverter 10HP Used Inverter 12HP Used (Capacity combined MMY- MMY- MMY- MMY- MMY- MMY- code) units 5HP ( 5) MAP0501T8 MAP0501T8 6HP ( 6) MAP0601T8...
