Please ensure that the following steps are taken:
Check the gradient for drainage flow as recommended in Figure B.
Provide clearance for easy servicing and optimal air flow as
shown in Figure C.
The indoor unit must be installed such that there is no short
circuit of the cool discharge air with the warm return air.
Do not install the indoor unit where there is direct
sunlight shining on the unit. The location should be
suitable for piping and drainage installation. The unit must be
a large distance away from the door.
Fig. B
Preliminary Site Survey
Electrical supply and installation shall conform to the local
authority (e.g. National Electrical Board).
Voltage supply fluctuation must not exceed ±10% of the rated
voltage. Electricity supply lines must be independent of weld-
ing transformers which can cause high supply fluctuation.
Ensure that the installation location is convenient for wiring
and piping.
Standard Mounting
Ensure that the overhead supports are strong enough to hold the
weight of the unit. Position the hanger rods (wall
mounting bracket for floor standing), and check for its
alignment with the unit. Also, check that the hangers are secured
and the base of the fan coil unit is leveled in both horizontal direc-
tions, taking into account the gradient for drainage flow as recom-
mended in Figure B.

The location must be well-ventilated, so that the unit
can draw in and distribute plenty of air thus lowering
the temperature.
A place capable of bearing the weight of the outdoor
unit as well as isolating noise and vibration.
A place protected from the direct sunlight. Use an
awning for protection if necessary. See Figure I.
Ensure that there is no obstruction to the air flowing
into or out of the unit. Remove any obstacles that block
the air intake or air discharge. See Figure G and H.
Install the outdoor condensing unit in such a way that
the hot air distributed cannot be drawn in again (as in
the case of short circuit of hot discharge air). Allow
sufficient space for maintenance work around the unit.
See Figure E and F.

! Caution
If the outdoor condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area),
sulfide gas (nearby hot spring or oil refinery plant), such substances may lead to failure of the unit.
REFRIGERANT PIPING
Maximum Pipe Length And Maximum Number Of Bends
If the pipe length is too long, both the capacity and the
reliability of the unit will decrease. As the number of bends
increases, resistance of the piping system to the refrigerant
flow increases and thus lowering the capacity, as a result
the compressor may become defective. See Figure N and
Figure O.

Piping Works And Flaring Technique
Do not use contaminated or damaged copper tubing. If any pipings, evaporator or condenser had been exposed or had been
opened for 15 seconds or more, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic,
rubber plugs and brass nuts from the valves, fittings, tubings and coils until it is ready to connect suction or liquid line into
valves or fittings.
If any brazing work is required, ensure that the nitrogen gas is passed through coil and joints while the brazing work is
being done. This will eliminate soot formation on the inside walls of the copper tubings.
Cut the pipe stage by stage, advancing the blade of the pipe cutter slowly. Extra force and deep cut will cause more
distortion on the pipe and thus extra burr. See Figure P.
1/4t
Cutting Copper Tube
Fig. Q
Fig. P
Remove Burr
Fig. R
Copper Tube
Swaging Block
Remove burrs from cut edges of the pipes with remover
as shown in Figure O. This will avoid unevenness on
the flare faces which will cause gas leak. Hold the end
of the pipe downwards to prevent metal chips from
entering the pipe.
Insert the flare nuts, mounted on the connection parts of
both the indoor unit and outdoor unit, onto the copper
pipes.
The exact length of pipe protruding from the face of the
flare die is determined by the flaring tool. See Figure R.
The table shows the use of an imperial die and rigid die.
Fix the pipe firmly on the flare die. Match the centers of
both the flare die and the flaring punch, and then tighten
the flaring punch fully.
Piping Connection To The Units
Align the center of the piping and tighten the flare nut
sufficiently with fingers.
Finally, tighten the flare nut with the 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.

5) Mount the valve stem nuts and service port nut.
Be sure to check for any gas leakage.
Vacuuming Procedure For 2 x 3 Way Valve
(See Figure T)
1) Open the suction and discharge service port cap.
2) Manifold gauge connection:
Low side hose from manifold gauge to the suction
service port.
High side hose from manifold gauge to the discharge
service port.
Service (center) hose from manifold gauge to the
vacuum pump.
3) Turn "ON" the power switch of the vacuum pump and
make sure that needle in the manifold gauge moved
towards -30 inHg (-76 cmHg).
4) Close the valve of both the low and high sides on the
manifold gauge, turn "OFF" the vacuum pump and
confirm that the gauge needle does not move
(approximately 3 minutes after turning "OFF" the
vacuum pump).
5) Disconnect the service hose from the vacuum pump.
Charging Procedure For 2, 3 Way Valve
(See Figure U)
1) Connect the service hose from manifold gauge to
the charging cylinder.
Connect the service hose, which you have
disconnected from the vacuum pump, to the valve at
bottom of the cylinder.
If you are using a gas cylinder, then use a scale and
reverse the cylinder so that the system can be charged
with liquid.
2) Purge the air from the service hose.
Open the valve at the bottom of the cylinder and
press the check valve suction on the manifold gauge
to purge the air (be careful with the liquid
refrigerant). The procedure is the same if you are
using a gas cylinder.
3) Open the valve (low side) on the manifold gauge
and charge the system with liquid refrigerant.
If the system cannot be charged with the specified
amount of refrigerant, then it should be charged little
by little (approximately 150g at each time) while
operating the air conditioner under cooling cycle.
However, one time is not sufficient, wait
approximately 1 minute and then repeat the
procedure.
4) Immediately disconnect the service hose from the
suction valve's service port.
6) After that, open the valve stem of the discharge and
suction valve counter-clockwise for the gas to run into
the indoor unit.
7) Check the low side pressure after turning "ON" the
compressor for 10 to 15 minutes.
