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.

INSTALLATION OF THE OUTDOOR UNIT

Fig. E

Fig. F

• 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.

Fig. G

Fig. H

• The installation location must not be susceptible to highly

concentrated dust, oil, salt or sulfide gas.

! 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.

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.

• 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.
