2.
When installing in a locations where there is heavy snowfall,
implement the following snow measures.
• Ensure the base is high enough that intakes are not clogged
by snow.
• Remove the rear intake grille to prevent snow from accumu-
lating on the fins.
3.
If condensate may drip on downstairs (or walkway) depending
on the floor condition, take a measure such as the installation of
central drain pan kit (sold separately).
4.
The refrigerant R410A itself is nontoxic, nonflammable and is
safe. If the refrigerant should leak however, its concentration
may exceed the allowable limit depending on room size. Due to
this it could be necessary to take measures against leakage.
See “14. CAUTION FOR REFRIGERANT LEAKS” for details.
4. INSPECTING AND HANDLING THE UNIT
• At delivery, the package should be checked and any damage
should be reported immediately to the carrier claims agent.
• When handling the unit, take into account the following:
1.
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2.
Decide on the transportation route.
3.
If a forklift is to be used, pass the forklift arms through the large
openings on the bottom of the unit. (Refer to figure 5)
4.
If hanging the unit, use a cloth sling to prevent damaging the unit.
Keeping the following points in mind, hang the unit following the
procedure shown in figure 6.
• Use a sling sufficiently strong to hold the mass of the unit.
• Use 2 belts of at least 8m long.
• Place extra cloth or boards in the locations where the casing
comes in contact with the sling to prevent damage.
•
Hoist the unit making sure it is being lifted at its center of gravity.
5.
After installation, remove the transportation clasp attached to the
large openings. (Refer to figure 6)
(Refer to figure 5)
1. Fork
2. Hole (large)
3. Transportation clasp (yellow)
4. Fixed screws of transportation clasp
(Refer to figure 6)
1. Belt sling
2. Board
3. Hole (large)
4. Hole (small)
Note
Apply a filler cloth on a fork to prevent coating of the bottom frame
from coming off and rust from occurring when bringing in the unit with
anti-corrosion treatment type using a forklift.
5. PLACING THE UNIT
• Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise. (Refer to figure 7)
• The base should be bigger around than the width of the unit’s legs
(66 mm), and should support the unit. (Refer to figure 8)
If protective rubber is to be attached, attach it to the whole face of
the base.
• The height of the base should be at least 150mm from the floor.
•
Secure the unit to its base using foundation bolts. (Use four com-
mercially available M12-type foundation bolts, nuts, and washers.)
•
The foundation bolts should be inserted 20 mm.
(Refer to figure 7)
1. The product cannot be supported
only with four corners.
2. Make sure to use the center sup-
ports.
3. Center of the product
(Refer to figure 8)
1. Foundation bolt point (φ15 dia. : 4 positions)
2. Depth of product
3. Width of support leg
Note
• There are restrictions on the refrigerant pipe connecting order
between outdoor unit in the case of the multi system.
See the Note in “2-1 Combination” for detail.
• When installing on a roof, make sure the roof floor is strong
enough and be sure to water-proof all work.
• Make sure the area around the machine drains properly by setting
up drainage grooves around the foundation.
Drain water is sometimes discharged from the outdoor unit when
it is running.
• For anti-corrosion type use nuts with resin washers. If the paint on
nut connections comes off, the anti-corrosion effect may
decrease.
6. REFRIGERANT PIPING
Note
• All field piping must be installed by a licensed refrigeration tech-
nician and must comply with relevant local and national regula-
tions.
• After piping work is complete, do not under any circumstances
open the shutoff valve until “7. FIELD WIRING” and “10. CHECK-
ING OF DEVICE AND INSTALLATION CONDITIONS” are com-
plete.
•
Do not use flux when brazing the refrigerant piping. Use the phos-
phor copper brazing filler metal
(BCuP-2: JIS Z 3264/B-Cu93P-
710/795: ISO 3677)
which does not require flux.
(Flux has extremely harmful influence on refrigerant piping sys-
tems. For instance, if the chlorine based flux is used, it will
cause pipe corrosion or, in particular, if the flux contains fluo-
rine, it will damage the refrigerant oil.)
6-1 Selection of piping material and Refrigerant
branching kit
• Use only pipes which are clean inside and outside and which do
not accumulate harmful sulfur, oxidants, dirt, cutting oils, mois-
ture, or other contamination. (Foreign materials inside pipes
including oils for fabrication must be 30mg/10m or less.)
• Use the following items for the refrigerant piping.
Material: Jointless phosphor-deoxidized copper pipe
Size: See “6-5 Example of connection” to determine the cor-
rect size.
Thickness: Select a thickness for the refrigerant piping which
complies with national and local laws.
For R410A, the design pressure is 4.0 MPa (40-bar).
The minimum thickness of piping according to Japan’s High-
Pressure Gas Safety Law (as of January 2003) is shown
below.
Temper grade (O type, 1/2H type) in the table indicate the
material types specified in JIS H 3300.
(unit: mm)
(unit: mm)
• For piping work, follow the maximum tolerated length, difference
in height, and length after a branch indicated in the “6-5 Example
of connection”.
• A refrigerant branching kit (sold separately) is needed for piping
branches and connection of piping between outdoor unit (in case
of multi system).
Use only separately sold items selected specifically according to
the refrigerant branch kit selection in the “6-5 Example of con-
nection”.
