1) Use drain plug for drainage.
2)
If the drain port is covered by a mOllllting base or floor surface, place
additional foot bases
of at least 30mm in height under the outdoor
unit's feet.
3) In cold areas,do not use a drain hose with the ontdoorunit. (Otherwise,
drain water may freeze, impairing heating perfonnance.)

INSTALLATION OF THE OUTDOOR UNIT
TIle ontdoor unit must be installed in snch a way, so as to
prevent short circuit
of thehot discharged air orobstruction to
the smooth air flow. Please follow the installation clearances
shown in the figure. Select the coolest possible place where
intake air temperature is not greater than the outside air
temperahrre (Refer to operating range).

Condensed Water Disposal Of Outdoor Unit
(Heat Pump Unit Only)
TIlere are 2holes on the base of OutdoorUnit forcondensed
water to flow out. Insert the drain elbow to one
of the
holes.
To install the drain elbow, first insert one portion
of the
hook to the base (portion A), then pull the drain elbow in
the direction shown
by the arrow while inserting the other
portion to the base.
Mter installation, check to ensure that
the drain elbow clings to base finnly.
If the unit is installed in a snowy andchilly area,condensed
water may freeze in the base. In such case, please remove
plug at the bottom
of unit to smooth the drainage.

Mounting Installation Plate
En sure that the wall is strong enough to withstand the weight
of the unit. Otherwise. it is necessary to reinforce the wall
with plates, beams or pillars.
Use the level gauge for horizontal mounting, fix it with
5 suitable screws for
20125 / 35 and 7 suitable screws for
50/ 60.
In case the rear piping draws out, drill a hole 65 mm in
diameter with a cone drill, slightly lower on the outside wall
(see figure).

The refrigerant piping can be routed to the unit in a number
of ways (left or right from the back of the unit), by using the
cut-out holes
on the casing of the unit (see fi gure). Bend the
pipes carefully to the required position in orderto align it with
the holes.
For the side and bottom ant, hold the bottom of the
pipingand then position it to therequireddirection (see fignre).
The condensation drain ho se can be taped to the pipes.

REFRIGERANT PIPING
Allowable Piping Length
If the pipe is too long, both the ca pacity and reliability of the unit will drop. As the number of bends increases, resistance to
the fl
ow of refrigerant sys tem increases, thus lowering cooling capacity. As a result, the compressor ma y become defective.
Always choose the shortest path and foll
ow the recommendations as tabulated below:

REFRIGERANT PIPING
Piping Works And Flaring Technique
Do not use contaminated or damaged copper tubing. If
any piping, evaporator or condenser had been exposed or
had been opened for
15 seconds or more, the system mu st
be vacuumed. Generally do not remove plastic, mbber
plugs and brass nuts from the valves, fittings, hlbing and
coils until it is ready to connect suction or liquid line into
valves or fittings.
If any brazing work is required, ensure that nitrogen gas
is passed through coil and joints while the brazing work
is being done.
lltis will eliminate soot fonnation on the
inside wall of copper hlbing s.
Cut the pipe stages by stages, advancing the blade of pipe
cutter slowly. Extra force and a deep cut will cause more
distortion of pipe and therefore extra burr. See Figure I.
Remove burrs from cut edges
of the pipes with remover. See
Figure II. Hold the pipe on top position and burr remover
at lower position to prevent metal chips from entering the
pipe. TIus will avoid unevenness on the flare faces wluch
will cause gas leak.
Insert the flare nuts, mounted on the connection parts
of both the indoor mut and outdoor mut, into the copper
pipes.
TIle exact length of pipe protmding from the top surface
of the swaging block is determined by the flaring tool.
See Figure III.
Fix the pipe fmulyon the swaging block. Match the centers
of both the swaging block and the flaring punch, then
tighten the flaring punch fully.
TIlC refrigerant pipe connection arc insulatcd by closed
cell polyurethane.
Piping Connection To The Units
Align the center of the piping and tighten the flare nut
sufficiently with fmger
s. See Figure IV.
Finally, tighten the flare nut with torque wrench until the
wrench clicks.
When tightening the flare nut with the torque wrench,
ensure that the tightening direction follows the arrow
indicated on the wrench.
The refrigerant pipe cOimection are insulated by closed
cell polyurethane.

SPECIALPRECAUTIONS WHEN DEALING WITH R410A UNIT
R410A is a new HFC refrigerant which does not damage the
ozone laye
r. The working pressure of tlils new refrigerant is
1.6 times lilgher tllan conventional refrigerant (R22), thus
proper installation
/se rvicing is essential.
Neveruse refrigerant other than
R410Ain an airconditioner
which is
de signed to operate witll R41OA.
POE or PYE oilis used as lubricant for R41 0Aco mpressor,
which is different from the mineral oil u se d f or R22
compressor. During installation or servicing,extraprecaution
must be taken not to expose tile
R410A system t oo long
to moist air. Residual
POE or PVE oil in tile piping and
components can absorb moisture from tile air.
To prev
ent mi scharging, the diameter of tile service port
on tile flare valve is different from that
of R22.
Use tools and materials exclusivelyfor refrigerantR41OA.
Tools exclusively for
R410A are manifold valve, charging
ho se, pressure gauge, gas leakdetector, flare t oo ls, torque
wrench, vacuum
pump and refrigerant cylinder.
As
an R410A air conditioner incurs higher pres s ure
than R22 units, it is essential to choose the copper pipes
correctly.
If the refrigerant gas leakage occurs during in stallation/
servicing, be sure to ventilate fully.
If the refrigerant gas
comes into contact with fire, a poisonous gas
may occur.
When installing or rem oving an air conditioner, do not
allow air
or moisture to remain in the refrigerant cycle.
VACUUMING AND CHARGING
Vacuuming is necessary to eliminate all moisture and air from the system.
Vacuuming The Piping And The Indoor Unit ,----------------------,
Except for the o utdoor unit which is pre-charged with
refrigerant, the indoor unit and tile refrigerant connection
pipes must be air-purged because tile air containing moisture
that remains in tile refrigerant cycle may cause malftmction
of the compressor.
Remove the caps from the valve and tile service port.
Connect the center
of tile charging gauge to tile vacuum
pump.
Connect the charging gauge to tile service port
of tile 3-way
valve.
Start tile vacuum pump. Evacuate for approximately 30
nilnutes. TIle evacuation time varies withdifferent vacuum
pump capacity. Confmn tllat the charging gauge needle ha s
mov
ed towards -760mmHg.
Caution
If tile gauge needle doe s not move to - 760 mmHg , be sure
to
check for leakage at flare type connection of the indoor
and outdoor milt and repair the leak before proceeding to
tile next step.
Close the valve
of tile changinggauge and stop the vacuum
pump.
On tile outdoor milt, open tile suction valve (3 way) and
liquid valve (2 way) (in anti-clockwisedirection) with 4mm
ke y for hexagon sacked screw.
Charge Operation
TIils operation must be done by using a gas cylinder and a
precise weighing machine.
The additional charge is topped-up
into the outdoor milt nsing the suction valve via tile
se rvice
port.
Remove the service port cap.
Connect tile
low pressure s ide of the charging gauge to tile
suction service port center
of the cylinder tank and clo se
tile lilgh pressure side of the gauge. Purge tile air from tile
service
ho se.
Start tile air conditioner unit.
Open tile gas cylinder and low pressure charging valve.
When the required refrigerant quantity is pumped into
tile milt, close the low pressure s ide and the gas cylinder
valve.
Disconnect the service
ho se from service port. Put back
tile service port cap.

ADDITIONAL CHARGE
TIle refrigerant is pre-charged in the outdoor unit. If the piping lengthis less than 7.Sm, then additional charge after vacuuming
is not neces sary. If the piping length is more than 7.5m , then use the additional charge value as indicated in the table.
