INSTALLATION AND MAINTENANCE
•
Select the installation location as shown in Fig 3.2:
a. Minimum Space
b. Down Slope Pitch of Drain Piping: 1/25~1/100
•
Consider the air distribution from the indoor unit to the space of the room, and select a suitable location so that uniform air
temperature distribution can be obtained in the room. It is recommended that the indoor unit should be installed 2.5 to 3 meters
high from the floor level.
•
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 oil vapour 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 severe 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
electromagnetic 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 at least 3 meters away 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 exchanger, do not install the indoor unit in an acid or alkaline environment. If the indoor
unit has to be installed in such environments, use corrosion-proof type unit.
Ensure that the number calculated below is lower than or equal to 0.3kg/m³. Otherwise it may cause danger situation if the refrigerant
in the outdoor unit leaks into the room where the indoor unit is installed.
