Piping Connection

• 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, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic, rubber

plugs and brass nuts from the valves, fittings, tubing 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.

This will eliminate soot formation on the inside wall of copper tubings.

• 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.

• Remove burrs from cut edges of pipes with a remover. This will avoid unevenness on the flare face which will cause gas leak.

• Align the center of the piping and sufficiently tighten the flare nut with fingers. Finally, tighten the flare nut with torque wrench

until the wrench clicks.

• Be sure to execute heat insulation. (polyurethane form with thickness more than 15 mm)

• Except the outdoor unit which is pre-charge with refrigerant, the indoor unit and the refrigerant connection pipes must be purged

because the air that contain moisture remaining in the refrigerant cycle may cause malfunction to the compressor.

Additional Charge

The refrigerant is pre-charged in the outdoor unit. If the piping length is less than 7.62m (25ft), then additional charge after

vacuuming is not necessary. If the piping length is more than 7.62m (25ft), then use the additional charge valve as indicated in

the table.

REFRIGERANT PIPING WORK

Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized

by the perfect piping work.

Piping Length And Elevation

If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to

flow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective.

Always choose the shortest path and follow the recommendation as tabulated below:

Remark: The refrigerant pre-charged in the outdoor unit is for piping length up to 7.62 m/25 ft.

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT

• R407C is a zeotropic refrigerant mixture which has zero ozone depletion potential and thus conformed to the Montreal

Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and perfor-

mance are about the same as the refrigerant R22.

• POE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for R22 compressor.

During installation or servicing, extra precaution must be taken not to expose the R407C system too long to moist air.

Residual POE oil in the piping and components can absorb moisture from the air.

• Refrigerant R407C is more easily affected by dust of moisture compared with R22, make sure to temporarily cover the

ends of the tubing prior to installation.

• No additional charge of compressor oil is permitted.

• No other refrigerant other than R407C.

• Tools specifically for R407C only (must not be used for R22 or other refrigerant)

i) Manifold gauge and charging hose

ii) Gas leak detector

iii) Refrigerant cylinder/charging cylinder

iv) Vacuum pump c/w adapter

v) Flare tools

vi) Refrigerant recovery machine

• Filter-dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise the contamination of

moisture and dirt in the refrigerant system. Filter-dryer must be of molecular sieve type. For a heat-pump system, install a

two-way flow filter dryer along the liquid line.

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. 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 R22

or R407C 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.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

R410A is a new HFC refrigerant which does not damage the

ozone layer. The working pressure of this new refrigerant is

1.6 times higher than conventional refrigerant (R22), thus

proper installation / servicing is essential.

• Never use refrigerant other than R410A in an air condi-

tioner which designed to operate with R410A.

• POE oil is used as lubricant for R410A compressor, which

is different from the mineral oil used for R22 compressor.

During installation or servicing, extra precaution must be

taken not to expose the R410A system too long to moist

air. Residual POE oil in the piping and components can

absorb moisture from the air.

• To prevent mischarging, the diameter of the service port

on the flare valve is different from that of R22.

• Use tools and materials exclusively for refrigerant R410A.

Tools exclusively for R410A are manifold valve, charging

hose, pressure gauge, gas leak detector, flare tools, torque

wrench, vacuum pump and refrigerant cylinder.

• As an R410A air conditioner incurs higher pressure than

R22 units, it is essential to choose the copper pipes cor-

rectly. Never use copper pipes thinner than 0.8mm even

though they are available in the market.

• If the refrigerant gas leakage occurs during installation /

servicing, be sure to ventilate fully. If the refrigerant gas

comes into contact with fire, a poisonous gas may occur.

• When installing or removing an air conditioner, do not

allow air or moisture to remain in the refrigerant cycle.

• R407C must be charged as liquid. Usually R407C cylinder is equipped with a dip-pipe for liquid withdrawal.

If there is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R407C from the valve.

• Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit thoroughly and

then charge the unit with fresh R407C according to the amount recommended in the specification.

INSTALLATION DE L’UNITÉ INTÉRIEURE

Etude Preliminaire Du Site

• L’alimentation électrique et l’installation doivent être conformes à la réglementation locale (p.ex. agréé EDF).

• Les fluctuations de tension du réseau doivent rester dans la limite de ±10% de la tension nominale. Le climatiseur ne doit

pas partager les lignes d’alimentation électrique avec des transformateurs de soudage, qui risquent de causer d’importantes

fluctuations.

• Assurez-vous que l’emplacement est pratique pour les branchements, la tuyauterie et l’évacuation.

• L’unité intérieure doit être installée de façon à ce qu’aucun obstacle ne bloque le refoulement d’air froid et l’entrée d’air

chaud et de façon à ce que l’air puisse se répandre dans la pièce (près du centre de la pièce).

• Un espace doit être ménagé entre l’unité intérieure et le mur et les obstacles comme le montre la figure.

• L’endroit d’installation doit être assez fort pour supporter une charge quatre fois supérieure au poids de l’unité intérieure

pour éviter l’amplification du bruit et des vibrations.

• L’endroit d’installation (surface du plafond) doit être plane et la hauteur du plafond d’au moins 350 mm.

• L’unité intérieure doit être à l’écart de sources de chaleur ou de vapeur (évitez de l’installer près d’une entrée).

Installation De L’unité

• Mesurez et marquez l’emplacement de la tige suspendue.

Percez un trou pour l’écrou d’angle dans le plafond et

fixez la tige suspendue).

• Le gabarit d’installation est allongé selon la température

et l’humidité. Vérifiez les dimensions utilisées.

• Les dimensions du gabarit d’installation sont les mêmes

que celles des dimensions de l’ouverture du plafond.

• Lorsque le travail de stratification du plafond n’est

pas terminé, veillez à fixer le gabarit d’installation sur

l’unité intérieure.

REMARQUE

Assurez-vous de discuter le perçage du plafond avec

les installateurs.

• Confirment au lancement de la tige accrochante selon le

Schéma 1.

• Mainrenez l’unité et accrochez-la à la tringle d’accrochage

à l’aide des écrous et des joints.

• Laissez un espace de 30,0 mm entre la surface inférieure

de l’unité intérieure et la surface du plafond.

• A l’aide d’un indicateur de niveau, assurez-vous que l’unité

est installée horizontalement et serrez l’écrou et le boulon

pour empêcher que l’unité ne tombe et ne vibre.

• Ouvrez le coffrage du plafond le long du bord extérieur

du gabarit d’installation en papier.
