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.

• Flare the pipe with extra length above the flaring tool as shown in the table below.

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:

• The flared edge must be even and not cracked or scratched.

• 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 water source heat pump unit which is pre-charge with refrigerant, the fan coil 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.

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 compres-

sor. 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 cyl-

inder.

• 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.

VACUUMING AND CHARGING

Purging the piping and the fan coil unit

Except for the water source heat pump unit which is pre-

charged with refrigerant, the fan coil unit and the refrigerant

connection pipes must be air-purged because the air

containing moisture that remains in the refrigerant cycle may

cause malfunction of the compressor.

• Remove the caps from the valve and the service port.

• Connect the center of the charging gauge to the vacuum

pump.

• Connect the charging gauge to the service port of the

3-way valve.

• Start the vacuum pump. Evacuate for approximately

30 minutes. The evacuation time varies with different

vacuum pump capacity. Confirm that the charging gauge

needle has moved towards -760mmHg.

Caution

• If the gauge needle does not move to -760mmHg, be sure

to check for gas leaks (using the refrigerant

detector) at flare type connection of the fan coil unit and

water source heat pump unit and repair the leak before

proceeding to the next step.

• Close the valve of the charging gauge and stop the vacuum

pump.

• On the water source heat pump unit, open the suction

valve (3 way) and liquid valve (2 way) (in anti-clockwise

direction) with 4mm key for hexagon sacked screw.

Additional Charge

• The pre-charged of R410A in water source heat pump

unit is suitable for standard pipe of length up to 2 meter

for 5WSS 07/10/15/16/20 AR.

• When the piping is more than the stated standard pipe

length, add additional charge of 18.5 gram/meter for

5WSS 07/10/15/16/20 AR.

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.

• Le ventilo-convecteur doit être installé de façon à ce qu’aucun obstacle ne bloque le jet d’air froid et la reprise de l’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 respecté entre le ventilo-convecteur et les murs et obstacles comme le montre la figure.

• La zone de l’installation doit être assez solide pour supporter une charge 4 fois supérieure au poids du ventilo-convecteur,

afin d’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.

• Le ventilo-convecteur 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.

• Avant que le travail de stratification du plafond ne soit

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

ventilo-convecteur.

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 mm entre la surface inférieure

du ventilo-convecteur 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.

Tuyauterie D’évacuation

• Le tuyau d’évacuation doit être incliné vers le bas pour

une évacuation facile.

• Evitez de positionner le tuyau vers le haut puis vers le

bas afin d’éviter que le flux d’eau ne soit inversé.

• Lorsque vous raccordez les tuyaux d’évacuation, assurez-

vous de ne pas exercer une pression supplémentaire sur

le raccord d’évacuation du ventilo-convecteur.

• Le diamètre extérieur du connecteur de drainage au tuyau

flexible est de 20 mm.

• Assurez-vous d’isoler le tuyau d’évacuation contre la

chaleur (mousse en polyéthylène de plus de 8,0 mm

d’épaisseur) afin d’éviter que l’eau condensée ne goutte

à l’intérieur de la piéce.

• Connectez le tuyau d’évacuation principal au tuyau

d’évacuation flexible.

• Envoyez de l’eau dans le tuyau d’évacuation flexible et

vérifiez qu’il n’y a pas de fuite dans la tuyauterie.

• Une fois le test terminé, raccordez le tuyau flexible au

raccord d’évacuation du ventilo-convecteur.
