1-3. Type of Copper Tube and Insulation Material

If you wish to purchase these materials separately from a local
source, you will need:
1. Deoxidized annealed copper tube for refrigerant tubing.
2. Foamed polyethylene insulation for copper tubes as
required to precise length of tubing. Wall thickness of the
insulation should be not less than 8 mm.
3. Use insulated copper wire for field wiring. Wire size varies
with the total length of wiring. Refer to 5. ELECTRICAL
WIRING for details.
CAUTION
Check local electrical codes and regulations before
obtaining wire. Also, check any specified instructions or
limitations.

1-4. Additional Materials Required for Installation

1. Refrigeration (armored) tape
2. Insulated staples or clamps for connecting wire (See your
local codes.)
3. Putty
4. Refrigeration tubing lubricant
5. Clamps or saddles to secure refrigerant tubing
6. Scale for weighing

1-5. Tubing Size

(A) Single type
● During tubing work, try to make both the tubing length (L)
and the difference in elevation (H1) as short as possible.
Refer to Table 1-3.

* If the total tubing length exceeds 30 m, charge the amount of refrigerant
as shown above in "Required additional refrigerant" for every 1 m in
excess of 30 m for outdoor units.

CAUTION
1. This unit requires no additional refrigerant charge up to
tubing length 30 m. In case of more than 30 m, additional
refrigerant charge is required. Refer to Table 1-3.
2. In case of multi type installation, indoor units should be
installed within the same room. If multi type indoor units
are installed in different rooms, temperature control may
develop problems because thermostat operation must
follow the thermostat condition of 1 indoor unit only (the
main unit).
WARNING
Always check the gas density for the room in which the unit
is installed.
■ Check of limit density
When installing an air conditioner in a room, it is necessary to
ensure that even if the refrigerant gas accidentally escapes, its
density does not exceed the limit level.
If the density might exceed the limit level, it is necessary to
1
set up an opening between it and the adjacent room, or to
install mechanical ventilation which is interlocked with the leak
1
detector.
(Total refrigerant charged amount: kg)
(Min. indoor volume where indoor unit is installed: m
< Limit density 0.3 (kg/m
The limit density of refrigerant which is used in this unit is
0.3 kg/m 3 (ISO 5149).
The shipped outdoor unit comes charged with the amount of
refrigerant fixed for each type, so add it to the amount that
is charged at the field. (Refer to the unit's nameplate for the
amount of charged refrigerant at shipment.)
Minimum indoor volume & floor area relative to the amount
of refrigerant are roughly as given in the following table.

CAUTION
Pay special attention to any location, such as a basement
or recessed area, etc. where leaked refrigerant can collect,
since refrigerant gas is heavier than air.

2. SELECTING THE INSTALLATION SITE

CAUTION
● When moving the unit during or after unpacking, make
sure to lift it by holding its lifting lugs. Do not exert
any pressure on other parts, especially the refrigerant
piping, drain piping and flange parts.
● If you think the humidity inside the ceiling might exceed
30°C and RH 80%, reinforce the insulation on the unit
body. Use glass wool or polyethylene foam as insulation
so that it is no thicker than 10 mm and fits inside the
ceiling opening.

2-1. Outdoor Unit

AVOID:
● heat sources and exhaust fans, etc. (Fig. 2-1)
● damp, humid or uneven locations.
DO:
● choose a place as cool as possible.
● choose a place that is well ventilated and outside air
temperature does not exceed maximum 45°C constantly.
● allow enough room around the unit for air intake/exhaust and
possible maintenance. (Fig. 2-2)

) ● use lug bolts or equal to bolt down unit, reducing vibration
and noise.
● If cooling operation is to be used when the outdoor air
temperature is –5°C or below, install a duct on the outdoor
unit.

maintenance and if a suffi cient maintenance space is provided
on the rear side (40 cm), the space of over 15 cm is enough at
the right side.
