A clearance of 50 mm or less between the top of the indoor unit and the end of the hanging bolt makes maintenance of the indoor heat exchanger easier. Air filter Hole for hanging bolt 4-14X30 Slot T erminal bed (power source) Solder joint refrigerant pipe (gas) 1 Drain pipe (outer diameter ø 32) (spontaneous drain) T erminal bed (transmission). 4.In case the inlet duct is used, remove the air filter (supplied with the unit) and then install the filter (field supply) on the suction side.

If you are using a field-supplied air filter, attach it in a location where the filter can be easily serviced. If you are using a field-supplied air filter, attach it in a location where the filter can be easily serviced.
