WARNING
It is important that you use extreme care in supporting the indoor unit inside the ceiling.
Ensure that the ceiling is strong enough to support the weight of the unit.
Before suspending the unit, test the strength of each attached suspension bolt.
(1) When placing the unit inside the ceiling, determine the pitch of the suspension bolts referring to the dimensional data given previously.
Tubing must be laid and connected inside the ceiling when suspending the unit.
If the ceiling is already constructed, lay the tubing into position for connection to the unit before placing the unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to protrude from the ceiling as shown in Fig. 3-5. (Cut the ceiling material, if necessary.)
(3) Suspend and fix the indoor unit using the 2 hexagonal nuts (field supply) and special washers (supplied with the unit) as shown in
Fig. 3-6.
CAUTION
Make sure the unit is installed level using a level or a vinyl hose
filled with water.
In using a vinyl hose instead of a level, adjust the top surface
of the unit to the surface of the water at both ends of the vinyl
hose and make horizontal adjustment on all 4 corners of the
unit.
If the air discharge side of the unit is installed downward,
splashing water or water leak may occur.
Also, the dust may accumulate inside the drain pan caused by
draining residual water.

3-4. Installing the Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain and use the
supplied drain socket to prevent water leaks.
The PVC pipe must be purchased separately.
When doing this, apply adhesive for the PVC pipe at the connection point.
(2) If connecting a drain socket (supplied) to the threaded drain port, first wrap the
drain port threads with sealing tape, then connect the joint. (Fig. 3-9)
(3) Ensure the drain pipe has a downward slant (1/100 or more). (See the
Fig. 3-10)
(4) The drain pipe with a trap should be installed away from the indoor unit.
(5) Do not forcibly install the drain pipe to the indoor unit tubing.
If forcibly installed, it may result in water leakage.
(6) The drain pipe should be fixed at the nearest of the indoor unit.
Failure to do so may result in water leakage.
(7) Do not attach any air purge equipment.
If attached, drain water may result in splashing out of the drain pipe.
(8) When the drain piping is completed, perform the water leak test and check for
a water leak.
If detected, it may result in water leakage or condensation.
(9) When the drain piping is completed, perform the drainage test if the water
drains smoothly.
If not draining smoothly, it may result in water leakage or condensation.
(10) When the drain piping work is finished securely, wrap the insulation material
around the indoor side drain pipe.
At this time, do not wrap together with the refrigerant tubing.
If wraped together, the drain pipe is lifted and water drainage will not be
operated.
Coincidentally, the water comes out of the drain pan and it can lead to water
leakage.

5. HOW TO PROCESS TUBING
5-1. Connecting the Refrigerant Tubing
Use of the Flaring Method
Many of conventional split system air conditioners employ the flaring method to connect refrigerant tubes that run between indoor and
outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts.
Flaring Procedure with a Flare Tool
(1) Cut the copper tube to the required length with a tube cutter.
It is recommended to cut approx. 30 – 50 cm longer than the tubing length
you estimate.
(2) Remove burrs at each end of the copper tubing with a tube reamer or file.
This process is important and should be done carefully to make a good flare.
Be sure to keep any contaminants (moisture, dirt, metal filings, etc.) from
entering the tubing. (Figs. 5-1 and 5-2)
NOTE
When reaming, hold the tube end downward and be sure that no copper scraps
fall into the tube. (Fig. 5-2)
(3) Remove the flare nut from the unit and be sure to mount it on the copper
tube.
(4) Make a flare at the end of the copper tube with a flare tool. (Fig. 5-3)
NOTE
A good flare should have the following characteristics:
•inside surface is glossy and smooth
•edge is smooth
•tapered sides are of uniform length
Caution Before Connecting Tubes Tightly
(1) Apply a sealing cap or water-proof tape to prevent dust or water from
entering the tubes before they are used.
(2) Be sure to apply refrigerant lubricant (ether oil) to the inside of the flare nut
before making piping connections.
This is effective for reducing gas leaks. (Fig. 5-4)
(3) For proper connection, align the union tube and flare tube straight with each
other, then screw on the flare nut lightly at first to obtain a smooth match.
(Fig. 5-5)
•Adjust the shape of the liquid tube using a tube bender at the installation site
and connect it to the liquid tubing side valve using a flare.
Cautions During Brazing
•Replace air inside the tube with nitrogen gas to prevent copper oxide film
from forming during the brazing process.
(Oxygen, carbon dioxide and Freon are not acceptable.)
•Do not allow the tubing to get too hot during brazing.
The nitrogen gas inside the tubing may overheat, causing refrigerant system valves to become damaged.
Therefore allow the tubing to cool when brazing.
•Use a reducing valve for the nitrogen cylinder.
•Do not use agents intended to prevent the formation of oxide film.
These agents adversely affect the refrigerant and refrigerant oil, and may cause damage or malfunctions.
