Installation Requirements
Table 2
1. Copper Tubing
Copper tubing, fittings and
insulation to interconnect the
suction (S) (wide tube) and liquid
(L) (narrow tube) refrigerant lines
between the indoor and outdoor
units can be purchased locally.
It is necessary to purchase the
following items:
- Purchase equal lengths of both
tubes and insulation required.
Cut the appropriate tube lengths,
30 to 40 cm (12 to 16 in.) longer
on each one to deepen vibration
between units. Wall thickness of
copper tube should be 0.8 mm
(0.0314 in.).
Both tubes must be well
insulated with proper insulation
materials.
- The length of wiring will
determine the wire size. See
local codes, refer to section of
electrical installation.
2. Additional Materials
- Saddles or clamps to hold
refrigerant tubing.
- Insulated clamps or staples
for connecting wire.
See local codes.
- Refrigeration oil and tape
(armored).
- Putty or similar filter.

Location and Preparation of Units
1. Choose a place as cool as possible.
The place should be well ventilated
and the inlet air should not hotter
than the outside temperature (max
45OC or 113OF).
2. Avoid the vicinity of heat sources,
exhaust fan, etc.
3. Avoid direct sunlight, provide
awnings if necessary.
4. The unit should be set on a level
reinforced concrete pad to avoid
the effect humidity. The minimum
height of the concrete pad should
be 100 mm. (4"). Unit shall be fixed
securely to the concrete pad with
bolts (not supplied) to prevent
abnormal noise and vibration.
5. The concrete pad must be
positioned a minimum of 200 mm.
(8") from any well and surrounding
shrubbery.
6. Minimum clearance on the inlet air
side of the unit must be 250 mm.
(10") : 1200 mm. (48") on the
discharge air side of the unit and
250 mm. (10") on the tubing side
of the unit (Figure 1).
7. When the unit is mounted on a roof,
be sure the roof will carry the unit’s
weight. Vibration isolation is
recommended to prevent
transmission to the building
structure.
Note
The Multi-Split System (Outdoor) Unit
should be installed as close to the
indoor units as possible.

9.52 (3/8) 350 - 400 (300 - 340)
12.70 (1/2) 500 - 550 (430 - 470)
1. The principal concerns in
refrigeration tubing are:
- Uniform oil return to the
compressor.
- Pressure drops and their effect on
system capacity.
- Tube routing and isolation to avoid
line breakage, vibration and sound
transmission. Regarding this, the
interconnecting refrigerant lines
should be simple and shorter as
much as possible.
2. Flare Connections
The units reported in this manual
employ the flare method to
interconnect refrigerant tubes between
indoor and outdoor units (Figure 2).
- The tube end of all refrigerant tubes
should be flared, the tube should
be cut and deburred. Be sure no
copper scraps fall in to the tube.
- Be sure to fit a cap to the open end
of the tube to keep it free of dust
and moisture.
- Avoid bending the tube. If it is
necessary, bend it gently, with a
radius of more than 3 or 4 cm.
(1 1/2 in. or 1 5/8 in.)
- Cut approximately 30 to 50 cm.
(12 in. to 20 in.) longer than
estimated tubing length.
- Before flaring remember to fit
the nut.
- Ream with tube end downward
to avoid copper scraps inside
the tube.
- Remove the flare caps on the
tube end.
- Connect the tubes by aligning
the centers of both flares and turn
the flare nuts by hand 3 or 4 turns
(Figure 3).
3. Insulate both lines, liquid (narrow
tube) and suction (wide tube), to
prevent heat loss and wet floor due to
dripping of chilled condensation.
Apply proper insulation material,
minimum thickness should be 8 mm
(1/3 in.) (Figure 4).
Note
Do not try to bend the tube after
installation.
4. Finish with armoring tape.
Also see section of condensate drain
piping.
Note
Apply refrigeration oil on flare and
union surfaces before connecting
them. This will reduce refrigerant
leakage.
- Check the tubing connections and
refrigerant lines before applying
specified torque. Fasten flare nuts
as recommended below.

Condensate Drain Piping
Figure 5
Drain
1. The drain hose should come
straight down the wall to a level
where runoff will not stain the wall.
2. There should be no traps and avoid
putting the end of the hose in water.
3. To avoid damage to the floor or
furniture when the drain hose is
placed in the room, insulate the
hose with foamed polyethylene
or equivalent.
4. After completing refrigerant lines,
wining and drain connection, bind
the tubing, wining and drain pipe
(check if local codes permit it) into
a bundle by using tape at 100 or
200 mm (4 in. or 8 in.) intervals.
Make sure the drain tube is at the
bottom of the bundle (Figure 5).

MS-SVN005-EN 9
System Evacuation and Purping
The outdoor unit is factory charged.
Unit nameplate charge is the total
required system charge with 7.5
meters of interconnecting lines. Since
the outdoor unit will not have to be
evacuated unless charge has been
completely lost, leave the suction and
liquid shut-off valves closed.
1. Upon completion of installation,
evacuate the refrigerant lines and
indoor coil (Figure 6).
2. Evacuate unit until the gauge reads
350 microns or evacuate at least
one hour for one system.
3. Close off valve to vacuum pump
and observe the micron gauge. If
gauge pressure rised above 500
microns in one (1) minute, then
evacuation is incompleted or
system is leaking.
- Attach appropriate hose from
manifold gauge to suction and
liquid line valves service ports.
- Attached center hose of mainfold
gauges to vacuum pump.
Note
Unnecessary switching of hoses and
complete evacuation of all lines
leading to sealed system can be
accomplished by placing a “T” in
manifold center hose and connecting
branch hose to cylinder of R-22.
Note
Evacuate unit 2 and 3 in the same
manner explained above.
This completes system evacuation
with a vacuum pump and the air
conditioner is ready for actual
operation.
