4.2 Initial Check

•
Install the indoor unit with a proper clearance around it for operation and maintenance working
space, as shown in Fig.4.1.
•
Check to ensure that the ceiling or wall has a sufficient strength to hang the indoor unit.
•
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 machinery shop or kitchen where vapor from oil enter into the
indoor unit. The oil deposits will adhere to components within the unit - including the heat exchanger,
which may corrode or weaken internal components.
•
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, etc.
(a) Do not install the indoor unit. There is a risk of electromagnetic interference particularly to the
wired controller, the electrical box and interconnecting wiring.
(b) Install the indoor unit and components as far as practical or at least 3 meters from the
electromagnetic source.
(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 corrosion to the heat exchangers, do not install the indoor unit in an acid or alkaline
environment.
