7.1 TRANSPORTATION AND HANDLING
!
C A U T I O N
•
Do not put any material on the product.
•
Do not step on the product.
7.1.1 Transportation of indoor unit
•
Transport the product as close to the installation location as
possible before unpacking.
•
Do not put any material on the indoor unit.
•
The indoor unit is packed upside down and therefore the
foamed polyethylene drain pan is exposed at the upper side.
Do NOT put the indoor unit with the drain pan side down
during the process from unpacking the indoor unit to hanging
up the unit to a ceiling. In addition, do NOT handle the indoor
unit by the drain pan portion or the air outlet portions.
•
As foamed polyethylene is used for the indoor unit, take care
when handling the indoor unit. Applying an excessive force
to the unit may cause a breakage.
7.1.2 Handling of indoor unit
!
D A N G E R
Do not put any foreign material into the indoor unit and check to
ensure that no foreign material exists in the indoor unit before
installation and the test run. Otherwise, a fire or failure, etc. may
occur.
!
C A U T I O N
•
Do not hold the resin covers when holding or lifting the indoor unit.
•
To avoid damage to the resin covers, put a cloth on them before lifting
or moving the indoor unit.
?
N O T E
When lifting or moving the indoor unit, use appropriate slings to avoid
damage and be careful not to damage the insulation material on units
surface.
8 INDOOR UNIT INSTALLATION
!
D A N G E R
•
Do not install the indoor units outdoors. If installed outdoors, an
electric hazard or electric leakage will occur.
•
Consider the air distribution from each indoor unit to the space
of the room, and select a suitable location so that uniform air
temperature in the room can be obtained.
•
Avoid obstacles which may hamper the air intake or the air
discharge flow.
•
Pay attention to the following points when the indoor units are
installed in a hospital or other places where there are electronic
waves from medical equipment, etc.:
-
Do not install the indoor units where electromagnetic wave is
directly radiated to the electrical box, remote control cable
or remote control switch.
-
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
tube.
-
Install a noise filter when the power supply emits harmful
noises.
-
Do not install the indoor units, outdoor unit, remote control
switch and cable within approximately 3 meters of strong
electromagnetic wave radiators such as medical equipment.
•
This unit is exclusive non electrical heater type indoor unit. It is
prohibited to install an electrical heater in the field.
•
Do not put any foreign material into the indoor unit and check to
ensure that none exist in the indoor unit before the installation
and test running. Otherwise a fire or failure, etc., may occur.
•
Do not perform installation work, refrigerant piping work, drain
pumping, drain piping and electrical wiring connecting work
without referring to the installation manual. If the instructions
are not followed, it may result in a water leakage, an electric
shock, a fire and an injury.
•
Mount suspension bolts using M10 (W3/8) as size, as shown
below:

C A U T I O N
•
Do not install the indoor units in a flammable environment to avoid a
fire or an explosion.
•
Check to ensure that the ceiling slab is strong enough. If not strong
enough, the indoor unit may fall down on you.
•
Do not install the indoor units in a machinery shop or kitchen where
vapour from oil or mist flows to the indoor units. The oil will deposit
on the heat exchanger, thereby reducing the indoor unit performance,
and may deform. In the worst case, the oil damages the plastic parts
of the indoor unit.
•
To avoid any corrosive action to the heat exchangers, do not install
the indoor units in an acid or alkaline environment.
•
When lifting or moving the indoor unit, use appropriate slings to avoid
damage and be careful not to damage the insulation material on units
surface.
