SAFETY PRECAUTIONS

Before installing the air conditioner unit, please read the following safety precautions carefully.

! Warning

• Installation and maintenance should be performed by qualified persons who are familiar with local code and

regulation, and experienced with this type of appliance.

• All field wiring must be installed in accordance with the national wiring regulation.

• Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring work

according to the wiring diagram.

• The unit must be GROUNDED to prevent possible hazard due to insulation failure.

• All electrical wiring must not touch the refrigerant piping, compressor and any moving parts of the fan motors.

• Confirm that the unit has been switched OFF before installing or servicing the unit.

IMPORTANT

DO NOT INSTALL OR USE THE AIR CONDITIONER UNIT IN A LAUNDRY ROOM.

! Caution

Please take note on the following important points when installing.

• Do not install the unit where leakage of flammable gas may occur.

If gas leaks and accumulates around the unit, it may cause fire ignition.

• Ensure that the drainage piping is connected properly.

If the drainage piping is not connected properly, it may cause water leakage which will dampen the

furniture.

• Do not overcharge the unit.

This unit is factory pre-charged. Overcharge will cause over-current or damage to the compressor.

• Ensure that the unit panel is closed after service or installation.

Unsecured panel will cause unit to operate noisily.

INSTALLATION OF THE INDOOR UNIT

Mounting

Ensure that the overhead supports are strong enough to hold

the unit’s weight. Position hanger rods and check for align-

ment with the unit. Check that hangers are secure and that

the base of fan-coil unit is level in the two horizontal direc-

tions, taking into account the gradient recommended for

drainage flow as shown.

Check the gradient recommended for drainage flow as

follow.

INSTALLATION OF THE OUTDOOR UNIT

Location For Installation

Install the outdoor unit in such way that air distributed by

the outdoor unit cannot be drawn in again (as in the case of

short circuit of discharge air). Allow sufficient space for

maintenance around the unit.

Ensure that there are no obstruction of air flow into or

out of the unit. Remove obstacles which block air intake

or discharge.

When two or more outdoor units are installed in a location,

they must be positioned such that one unit will not be taking

the discharge air from another.

This also applies when two or more units are installed one

above the other. The units must all face the same direction,

or opposite direction (back to back), such that air short circuit

does not occur.

The location must be well ventilated, so that the unit can draw and distribute plenty of air.

A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.

A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.

A place where smooth drainage of rain water and water formed by defrosting is acceptable.

A place where the unit will not be buried in snow.

A place where air outlet port is not exposed to strong wind.

A place where the air discharge and operating sound level will not annoy the neighbours.

The location must not be susceptible to dust or oil mist.

Provide clearance for servicing and optimal air flow as

shown in the diagram.

The indoor unit must be installed such that there is no short

circuit of cool discharge with air discharge.

Respect the installation clearance.

*for free return of air

If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area),

sulfide gas (near hot spring, oil refinery plant), such substances may lead to failure of the unit.

REFRIGERANT PIPING

Maximum Pipe Length And Maximum No. Of Bends

When the pipe length becomes too long, both the capacity and reliability will drop and as the no. of bends increases, system

piping resistance to the refrigerant flow increases, thus lowering the capacity. As a result the compressor may fail. Always

choose the shortest path and follow the recommendations as tabulated below:-

Max. Elevation 10m 10m 10m 20m 20m

Max. no. of Bends 10 10 10 10 10

Bending must be carefully made so as not to crush the pipe. Use a pipe bender to bend a pipe where possible.

Our guarantee on the performance of our air-conditioners is strictly revoked if the height, length and/or no. of bends

of the refrigerant piping system installed is beyond the limit above.

Special Precautions When Mounting TXV Bulb

• TXV bulb should be clamped to the suction line near the evaporator outlet, and if possible, on a horizontal run.

• Clean suction line completely before clamping the bulb in place.

• Clamp the bulb to a free draining suction line.

• Insulate the remote bulb from ambient.

Note: After installation is done, the TXV bulb must be fixed at suction line at 8 o’clock or 4 o’clock.

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.

Piping Works & Brazing 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.

• Remove burrs from cut edges of the pipes with remover as

shown in the figure. Hold the end of the pipe downwards to

prevent metal chips from entering the pipe.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with

flare valve fittings.

Vacuuming

Before vacuuming, perform leak check for refrigeration

circuit. After the system piping are properly connected,

connect the flexible hoses to the correct charging nipples as

shown in the diagram. Ensure that flexible hose from charging

nipples are connected to the vacuum pump via standard

servicing valves and pressure gauges (gauge manifold).

Vacuum the air conditioner system to at least 500 microns

Hg. Do not start the unit when the system is engaged in

vacuuming.

Charging

Before charging, the vacuum must be held at 500 microns Hg

for at least 15 minutes, then break vacuum by charging R-22

refrigerant. Operate the unit for 15 minutes and ensure the

refrigerant charges is of correct by monitoring running current,

gas and liquid line pressures. Suction and discharge pipe

pressure should be in the region of 75 psig and 275 psig

generally.

After ensuring the system is correctly charged, remove flexible

hose from charging nipples and replace caps.
