7 UNIT INSTALLATION
•
The installation of a specific remote controller is necessary
during the installation comissioning. Once the installation co-
missioning is finished, this remote controller can be removed
if the pin 7 is switched to ON position. In this case, pay atten-
tion to all the setting details related with the remote controller
because after remove it, they cannot be changed.
•
Do not install the DX-Interface where electromagnetic wave
is directly radiated to the control box or expansion valve box.
•
Install a noise filter when noise is emitted from power supply.
•
Do not install the DX-Interface where generation, flowing, sta-
ying or leakage of flammable gas may occur.
•
When the false ceiling contains high humidity, dew conden-
sation water may occur on the outer surface of the expansion
valve box. Therefore utilize the insulation on the outer surface
of the expansion valve box.
Installation Location
1 Installation methods are selectable according to the dimen-
sion of the false ceiling.
2 Keep the distance between the unit or device with heat ex-
changer and the expansion valve box for the piping length
up to 5m. Also the elevation difference between the unit or
device with heat exchanger and the expansion valve box must

be no more than 2m.
3 Check the ceiling slab is strong enough. If the ceiling slab is
too weak to support the weight of the expansion valve box,
noise and vibration may occur.
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 vapor or
mist flows. Dew condensation water may occur on the expan-
sion valve box while cooling operation. In this case, utilize 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.
