Selecting The Mounting Position - Fujitsu AIR CONDITIONER Installation Manual

To install a unit that uses R32 refrigerant, use dedicated tools and piping materials that
have been manufactured specifically for R32(R410A) use. Because the pressure of R32
refrigerant is approximately 1.6 times higher than R22, failure to use dedicated piping
material or improper installation can cause rupture or injury. Furthermore, it can cause
serious accidents such as water leakage, electric shock, or fire.
Do not use a vacuum pump or refrigerant recovery tools with a series motor, since it
may ignite.
2.2. Power
Always use a special branch circuit and install a special receptacle to supply power to
the room air conditioner.
Use a circuit breaker and receptacle matched to the capacity of the air conditioner.
Install a leakage circuit breaker in accordance with the related laws and regulations
and electric company standards.
The circuit breaker is installed in the permanent wiring. Always use a circuit that can
trip all the poles of the wiring and has an isolation distance of at least 3 mm between
the contacts of each pole.
The power source capacity must be the sum of the air conditioner current and the cur-
rent of other electrical appliances. When the current contracted capacity is insufficient,
change the contracted capacity.
When the voltage is low and the air conditioner is difficult to start, contact the power
company the voltage raised.
2.3. Electric requirement
Be sure to install a breaker of the specified capacity.
Regulation of cables and breaker differs from each locality, refer in accordance with local rules.

Select the breaker that enough load current can pass through it.
• Before starting work check that power is not being supplied to all poles of the indoor
unit and outdoor unit.
• Install all electrical works in accordance to the national standard.
• Install the disconnect device with a contact gap of at least 3 mm in all poles nearby the
units. (Both indoor unit and outdoor unit)
• Install the circuit breaker nearby the units.

3. SELECTING THE MOUNTING POSITION

• Decide the mounting position with the customer as follows.
• Do not set to a place where there is oily smoke, oil is used in the factory, the unit can
contact sea breeze, sulfide gases will be generated in the hot spring area, corrosive
gases will be generated, animal may urine on the unit and ammonia will be generated
and a dusty place.
3.1. Outdoor unit
(1) If possible, do not install the unit where it will be exposed to direct sunlight.
(If necessary, Install a blind that does not interfere with the air flow.)
(2) Do not install the unit where a strong wind blows or where it is very dusty.
(3) Do not install in an area that has heat sources, vapors, or the risk of leakage or
accumulation of flammable gas.
(4) Do not install the unit where people pass.
(5) Take you neighbors into consideration so that they are not disturbed by air blowing
into their windows or by noise.
(6) Provide the space shown in figure so that the airflow is not blocked. Also for efficient
operation, leave open three of the four directions front, rear, and both sides.
(7) Install the unit where keep away more than 3 m from the antenna of TV set and Radio.
(8) Outdoor unit should be set to a place where both drainage and itself will not be
affected when heating.
