5. INDOOR UNIT INSTALLATION
As for the parts to be used for installation work, be sure to
use the provided accessories and specified parts desig-
nated by our company.
(1)
Install the indoor unit temporarily.
•
Attach the hanger bracket to the suspension bolt. Be sure
to fix it securely by using a nut and washer from the upper
and lower sides of the hanger bracket.
(Refer to Fig. 5)
[ PRECAUTION ]
Since the unit uses a plastic drain pan, prevent welding
spatter and other foreign substances from the air outlet
during installation.
(2)
Adjust the height of the unit.
(3)
Check the unit is horizontally level.
CAUTION
•
Make sure the unit is installed level using a level or a
plastic tube filled with water. In using a plastic tube
instead of a level, adjust the top surface of the unit to the
surface of the water at both ends of the plastic tube and
adjust the unit horizontally. (One thing to watch out for in
particular is if the unit is installed so that the slope is not
in the direction of the drain piping, this might cause leak-
ing.)
(4)
Tighten the upper nut.
6. REFRIGERANT PIPING WORK
For refrigerant piping of outdoor units, see the installation
manual attached to the outdoor unit.
Execute heat insulation work completely on both sides of
the gas piping and the liquid piping. Otherwise, a water
leakage can result sometimes.
Use insulation that can withstand temperatures of at least
120°C. Reinforce the insulation on the refrigerant piping
according to the installation environment. If the tempera-
ture above the ceiling might reach 30°C or the humidity
RH80%. Condensation may form on the surface of the insu-
lation.
CAUTION
Follow the points at below.
•
Use a pipe cutter and flare suitable for the type of refrigerant.
•
Apply ester oil or ether oil to the flare section when using a
flare connection.
•
Only use the flare nuts included with the unit. Using different
flare nuts may cause the refrigerant to leak.
•
To prevent dust, moisture or other foreign matter from infil-
trating the piping, either pinch the end or cover it with tape.
•
Do not allow anything other than the designated refrigerant
to get mixed into the refrigerant circuit, such as air, etc. If any
refrigerant gas leaks while working on the unit, ventilate the
room thoroughly right away.
(1)
Connect the piping.
•
The outdoor unit is charged with refrigerant.
•
Be sure to use both a spanner and torque wrench together,
as shown in the drawing, when connecting or disconnecting
pipes to/from the unit. (Refer to Fig. 6)
•
Refer to the Table 1 for the dimensions of flare nut spaces.
•
Apply ester oil or ether oil to flare section (both inside and
out) when using flare nut connections and then turn 3 or 4
times by hand. (Refer to Fig. 7)
(3)
Attach the filter to the
main unit while pushing
down on the bends.
