4 Secure proper space around the control box and expansion valve box for operation and maintenance work. Also a
service access door should be prepared in order to remove the DX-interface without getting rid of the ceiling plate.
5 Select a suitable and convenient location for the refrigerant piping connection.
6
Do not install the DX-Interface in a kitchen where vapour or mist flows. Dew condensation water may occur on the
expansion valve box while cooling operation. In this case, use the insulation.
7 Do not install the DX-Interface in a organic solvent (thinner or benzine) environment. Synthetic resin parts may
dissolve.
8
Do not install the DX-Interface where generation, flowing or staying of flammable gas may occur.
9 The sound of refrigerant running through from the expansion valve box may be heard. Therefore install the expansion
valve box where the sound will not leak such as in the false ceiling of a hall way.
10 Use ceiling material with sound-proof such as plaster board.
