• Use conformed cable with Type245 IEC57.
• 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.

2.6. Additional charge
Refrigerant suitable for a piping length of 15 m is charged in the outdoor unit at the factory.
When the piping is longer than 15 m, additional charging is necessary.
For the additional amount, see the table below.
Pipe length
15 m
20 m
Rate
Additional refrigerant
None
+100 g
20 g/m
CAUTION
When adding refrigerant, add the refrigerant from the charging port at the completion
of work.
The maximum length of the piping is 20 m. If the units are further apart than this, correct
operation can not be guaranteed.
Between 15 m and 20 m, when using a connection pipe other than that in the table, charge
additional refrigerant with 20 g/1 m as the criteria.
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, sul
¿
de 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
À
ow.)
(2) Do not install the unit where a strong wind blows or where it is very dusty.
(3) Do not install the unit where people pass.
(4) Take you neighbors into consideration so that they are not disturbed by air blowing into their
windows or by noise.
(5) Provide the space shown in
¿
gure so that the air
À
ow is not blocked. Also for ef
¿
cient
operation, leave open three of the four directions front, rear, and both sides.
(6) Install the unit where keep away more than 3m from the antenna of TV set and Radio.
(7) Outdoor unit should be set to a place where both drainage and itself will not be
affected when heating.
WARNING
Install at a place that can withstand the weight of the outdoor units and install positively
so that the units will not topple or fall.
CAUTION
Do not install where there is the danger of combustible gas leakage.
Do not install near heat sources.
In places where the outdoor temperature drops to 0
Û
C or lower, the drain water may
freeze and may stop up the drain or cause other outdoor unit trouble. Therefore take
measures so that the drain water will not freeze and clog the drain.
In the area with heavy snowfall, if the intake and outlet of outdoor unit is blocked with
snow, it might become dif
¿
cult to get warm and it is likely to cause of the breakdown.
Please construct a canopy and a pedestal or place the unit on a high stand (local
con
¿
gured).
If children under 10 years old may approach the unit, take preventive measures so that
they cannot reach the unit.

and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may
freeze in extreme cold weather. (Reverse cycle model only)
