Location and Preparation of Units
Indoor Unit
1. Select a convenient location that
allows the air to reach every corner
of the room and where it is easy to
route the refrigerant tubing, wiring
and drain to the outside.
2. The ceiling construction should be
strong enough to support the
weight of the unit.
3. The refrigerant tubing, drain piping
and wiring conduit are connected
through the wall.
4. Refrigerant tubes between the
indoor and the outdoor units and
drain pipes should be as short as
possible (Figure 1).
5. If a refrigerant charge adjustment is
necessary, follow the Installation
Manual for the Outdoor Unit.
Outdoor Unit
See instructions for location and
preparation of the unit in the Installation
Manual for the Outdoor Unit.
Installation Method:
Indoor Unit
After selecting the location to place
the unit, follow these steps:
1. Make a hole in the wall to route
tubing and wiring through a locally
purchased PVC pipe. The hole
should slope downwards slightly,
towards the outside (Figure 2).
Figure 1
2. Before cutting, check that no pipes
or studs are directly behind the
place to be cut. Avoid areas where
electrical wiring or conduits are
located.
3. Hang the unit on a solid and level
roof. Noise, vibration or leakage
could occur on and unstable
foundation (Figure 3,4).
For correct installation of duct
work see (Figure 6).
4. Support the unit solidly.
5. To have access to electrical
terminals, remove the right side
junction box (Figure 2).
6. Note that refrigerant tubing,
interconnecting wiring and drain
hose should go through the wall.
Shape these items so that they will
easily fit through the wall.
Figure 2
Outdoor Unit
See the proper installation method
provided in the Installation Manual
for the Outdoor Unit.
Installation Requirements
Important
- Read the Installation Manual
completely before installing and
operating the system.
-Turn on the mains power at least
five (5) hours before operating

- Drill
-Torque wrench
- Adjustable wrench
- Standard screwdriver
- Phillips head screwdriver
- Knife or wire stripper

Caution
Check local electrical codes and
regulations before buying any wire.
Also check for any specitic wiring
instructions or limitations.
3. Additional Materials Required
for Installation
- Saddles or clamps to secure
refrigerant tubing.

Connection of Refrigerant Tubing
Proper installation prodecure is
recommended in the Installation
Manual Package, usually provided
together with the outdoor unit. It is
advisable to read bofore installing.
The indoor unit refrigerant connections
are located on the left hand side when
facing the unit (Figure 7).
Figure 7
Connecting the Units with
Flaring Procedure.
1. Cut the copper tube to the required
length with a tube cutter. It is
recommended to cut approx.
20-30 cm. longer than the tubing
length.
2. Remove burrs at the end of the
copper tube with a tube reamer
or file, as shown in Figure 8.
Figure 8
Copper
Tubing
Reamer
When reaming, hold the tube end
downward and be sure that no copper
scraps fall into the tube (Figure 9).

After
Figure 9
3. Remove the flare nut from the unit
and be sure to insert on the copper
tube.
4. Make a flare at the end of the copper
tube with a flare tool (Figure 10).
Flare Nut
Copper Tubing
Flare Tool
Figure 10
A good flare should have the
following characteristics:
• Inside surface is glossy and smooth.
• Edge is smooth.
•Tapered sides are of uniform
length.
Cautions Before Connecting
Tightly
1. Be sure to apply a sealing cap or
water-proof tape to prevent dust or
water from getting into the tubes
before they are used.
2. Be sure to apply refrigerant
lubricant to the matching surfaces
of the flare and union before
connecting them together. This is
effective for reducing gas leaks
(Figure 11).
Figure 11
Apply refrigerant lubricant here
3. For proper connection, align the
union tube and flare tube straight
with each other, then screw in the
flare nut lightly at first to obtain a
smooth match (Figure 12).
Union Flare Nut
Figure 12
4. Tighten the flare nuts, using the
appropriate wrench.
Connecting the Unit with
Brazing Prodecure
1. Cut the copper tube to the required
length with a tube cutter. It is
recommended to cut approx.
20-30 cm. longer than the tube length.
2. Remove burrs at the end of the
copper tube with a tube reamer
(Figure 8).
3. There are 2 ways to connect the
copper tube
- Use a coupling between the
copper tube of Fan Coil Unit and
the copper tube used for
installation (Figure 13).

- Expand the copper tube by
using a swaging tool set as in
Figure 14.

4. To braze the copper tube, before
brazing a copper tube to a solder
coupling or a copper tube to an
expanded tube, do not forget to
keep them tight as shown in
Figure 15.

Condensate Drain Piping
Condensate Drain Piping
1. The drain hose should run straight
down the wall to a level where the
run off will not stain the wall.
2. These should have water traps.
Avoid putting the end of the hose in
water.
3. To conveniently drain the system,
the drain piping must slant
downward, with a slope of at least
1:50 to prevent leakage.
4. When the drain hose is placed in
the room, insulate the hose with
foam polyethylene to avoid damage
to the ceiling or furniture.
5. After completing installation of
refrigerant lines, wiring and drain
connections, bind the tubing,
wiring and drain piping (check if
local codes permit binding) into a
bundle by using tape at 100 or 200
mm (4" to 8") intervals. Make sure
the drain tube is at the bottom of
the bundle (Figure 16).

Electrical Installation
Electrical Installation
All wiring and grounding must comply
with local electrical codes.
Wiring Important Safeguards:
- Check the unit nameplate for
electrical rating. Be sure wiring is
done according to local codes and
wiring diagram.
- Use a separate power line with
circuit breaker for each air
conditioning unit.
- Connect electrical ground to all
units.
- Wiring should not touch refrigerant
tubing, compressor, motors or
moving parts.
- The manufacturer will accept no
responsibility for problems caused
by unauthorized changes in the
internal wiring.
- Connect the wiring firmly.
Indoor Unit
Remove the right side junction box
(see previous instructions) to access
the terminal base.
System Wiring Routing
- Pass the system wiring through the
PVC pipe, referred to in the Section
of Installation Method (both power
and control lines) to interconnect
indoor and outdoor units.
- Connect the wire terminals to the
terminal base. See connection
indication on system wiring
diagram.
- Make sure all connections are tight.
Outdoor Unit
See the electrical installation
instructions in the Installation Manual
for the Outdoor Unit.

Regular Maintenance
Be sure to disconnect the power
before inspection or maintenance of
air conditioner.
1. Cleaning the air filter
Air flow is reduced and cooling
efficiency impaired if the filter is
clogged. Be sure to clean the filter
every two weeks during the cooling
season.
1.1 How to remove the air filters
- Loose screws located under
the filter in return air plenum
set.
- Remove air filter frame from
return air plenum set.
1.2 How to clean the air filter.
-Wash away dust from the air
filter with clean water or
vacuum it with an electric
vacuum cleaner.
Note:
Once the air filter is washed,
dry it completely before returning it to
its original position.
After cleaning be sure to return it to its
original position.
Cautions
- Do not wash the air filter in water
that is over 40ºC or it may shrink.
- Do not expose the air filter to fire.
- Do not expose the air filter to direct
sunlight for a long time.
- Clean the air filter more frequently
Figure 8
when the air is very dirty.
