Min. 1000
•
Consider the air distribution from the indoor unit to the space of the room, and select a suitable
location so that uniform air temperature in the room can be obtained.
•
Do not install flammable parts in the service space for the indoor unit.
•
Avoid obstacles which may hamper the air intake or the air discharge flow.
•
Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its mist flows to
the indoor unit.
The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance, and may
deform and in the worst case, break the plastic parts of the indoor unit.
•
Pay attention to the following points when the indoor unit is installed in a hospital or other facilities
where there are electronic waves from medical equipment.
(a) Do not install the indoor unit where the electromagnetic wave is directly radiated to the electrical
box, remote control cable or remote control switch.
(b) Install the indoor unit and components as far as practical or at least 3 meters from the
electromagnetic wave radiator.
(c) Prepare a steel box and install the remote control switch in it. Prepare a steel conduit tube and
wire the remote control cable in it. Then, connect the ground wire with the box and the tube.
(d) Install a noise filter when the power supply emits harmful noises.
•
To avoid any corrosive action to the heat exchangers, do not install the indoor unit in an acid or
alkaline environment.
