Panasonic FY-250ZDY2 Manuel D'installation page 3

Provide an exclusive circuit breaker that can completely break
contacts on all the poles by more than 3mm through direct
connection to the power terminals. Depending upon the
environment for installation, it becomes necessary to install an
earth leakage breaker.
When you want to pierce the metal duct through the metal lath
or the wire lath or the metal plate of the wooden facility, do not
forget to insulate electrically between the duct and the wall.
Otherwise, it would cause an electric shock or an electric
leakage.
Don't use other parts than specified (including the auxiliary
parts) for installation works. If you do not use the specified
parts, it is likely to cause a drop of the unit, a fire, an electric
shock, etc.
Install the outdoor duct in a falling gradient toward the outside
so as to prevent water from coming in. If it is not installed so, the
building is likely to be flooded, wetting the household effects.
Heat-insulate the outdoor duct (including the indoor side, if
necessary) to prevent dewing. If heat insulation is not adequate,
water likely goes indoor and wets the household properties.
When it is high humid and high temperature inside the ceiling, a
ventilation system must be installed inside the ceiling.
Otherwise, it could cause a fire or an electric leakage.
Connect the power line and the connecting line with accuracy
using the specified cables and fix them firmly so as not to put
the outer stress of the cables on the pin connecting area.
Incomplete connection or fixing is likely to cause a heat
generation or a fire.

CAUTION
Install the power line and the connecting line with accuracy so the
power source cover may not float. If the installation of the power
source cover is inappropriate, the pin connection area is likely to
cause a heat generation, a fire and an electric shock due to dust
or powder.
Never install the unit near the place where there is a fear of
leakage of an inflammable gas. If gas happens to leak and stays
around the unit, it is likely to cause a fire.
Don't use the unit at the other voltages than the rated one. It
could cause a fire or an electric shock.
Do not install the unit in locations with large amounts of oily
smoke, such as food preparation areas. It could cause a fire.
Don't install the unit at the place of a high temperature or a flame.
It could cause a heat generation or a fire.
Do not install in locations where harmful or corrosive gasses may
be present (i.e. acidic, alkali, organic solvent, paint gasses etc.
from machinery or factories). Installation in such a location could
cause a gas-poisoning and a fire.
Do not install in locations with high humidity, such as close to
bathroom etc. It could cause an electric shock or an electric
leakage etc.
