Electrical Requirement; Selecting The Mounting Position - Fujitsu Slim Duct Type Installation Manual

4. ELECTRICAL REQUIREMENT

Always make the air conditioner power supply a special
branch circuit and provide a special switch and receptacle. Do
not extend the power cable.
Refer to local codes for acceptable cable type.
Cable Cable size
Connection cable 14 AWG
Max. Cable Length: Limit voltage drop to less than 2%. In-
crease cable gauge if voltage drop is 2% or more.

5. SELECTING THE MOUNTING POSITION

Correct initial installation location is important because it is
difficult to move unit after it is installed.
Select installation locations that can properly support the
weight of the indoor. Install the units securely so that they do
not topple or fall.
Do not install the unit in the following areas:
• Area with high salt content, such as at the seaside.
It will deteriorate metal parts, causing the parts to fail or the
unit to leak water.
• Area filled with mineral oil or containing a large amount of
splashed oil or steam, such as a kitchen.
It will deteriorate plastic parts, causing the parts to fail or
the unit to leak water.
• Area that generates substances that adversely affect the
equipment, such as sulfuric gas, chlorine gas, acid, or
alkali.
It will cause the copper pipes and brazed joints to corrode,
which can cause refrigerant leakage.
• Area that can cause combustible gas to leak, contains
suspended carbon fibers or flammable dust, or volatile
inflammables such as paint thinner or gasoline.
If gas leaks and settles around the unit, it can cause a fire.
• Area where animals may urinate on the unit or ammonia
may be generated.
Do not use the unit for special purposes, such as storing
food, raising animals, growing plants, or preserving precision
devices or art objects.
It can degrade the quality of the preserved or stored objects.
Do not install where there is the danger of combustible gas
leakage.

WARNING
CAUTION
CAUTION
Do not install the unit near a source of heat, steam, or
flammable gas.
Install the unit where drainage does not cause any trouble.
Install the indoor unit, outdoor unit, power supply cable,
and remote control cable at least 40 in. (1 m) away from a
television or radio receivers. The purpose of this is to prevent
TV reception interference or radio noise.
(Even if they are installed more than 40 in. (1 m) apart, you
could still receive noise under some signal conditions.)
If children under 10 years old may approach the unit, take
preventive measures so that they cannot reach the unit.
• Decide the mounting position with the customer as
follows:
(1) Install the indoor unit on a place having a sufficient strength
so that it withstands against the weight of the indoor unit.
(2) The inlet and outlet ports should not be obstructed; the air
should be able to blow all over the room.
(3) Leave the space required to service the air conditioner.
(4) A place from where the air can be distributed evenly
throughout the room by the unit.
(5) Install the unit where connection to the outdoor unit is easy.
(6) Install the unit where the connection pipe can be easily
installed.
(7) Install the unit where the drain pipe can be easily installed.
(8) Install the unit where noise and vibrations are not amplified.
(9) Take servicing, etc., into consideration and leave the spaces.
Also install the unit where the filter can be removed.
