a) For ceiling mounted models, locate a position where piping and ducting work can be kept to a minimum.
Ensure that overhead supports are strong enough to hold the unit’s weight. Position hanger rods and
check for alignment with the unit. Check that hangers are secure and that the base of fan-coil unit is level
in two horizontal directions.

After all electrical wiring is completed and the system is charged with refrigerant, make sure unit is operating
properly. Check that:
a) Condenser fans are running, with warm air blowing off the condenser coil.
b) Evaporator blowers are running and discharging cool air.
c) Suction line inside condensing unit feels cool.
d) Liquid line inside condensing unit feels warm.

precautions:
a) Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring
work.
b) Provide a power outlet to be used exclusively for each unit. A power supply disconnect and a circuit
breaker for over-current protection should be provided in the exclusive line.
c) The unit must be GROUNDED to prevent possible hazard due to insulation failure.
d) Allwiringmustbermlyconnected.
e) Electrical wiring must not touch the refrigerant piping, compressor and any moving parts of the fan
motors.

The indoor unit must be installed such that there is no short circuit of cool discharge with air discharge.
Respect the installation clearance.
Do not put the indoor unit where there is direct sunlight on unit. The location is suitable for piping and
drainage and it must be have a large distance between a door and unit.

As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to
achievemaximumcoolingcapacity,thelocationselectedshouldfulllthefollowingrequirements:-
a) Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit
cannotbedrawninagain(asinthecaseofshortcircuitofhotdischargeair).Allowsufcientspacefor

b) Ensurethatthereisnoobstructionofairowintooroutoftheunit.Removeobstaclewhichblockair
intake or discharge.
c) The location must be well ventilated, so that the unit can draw and distribute plenty of air thus lowering
the condensing temperature.
d) A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
e) A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.
f) A place where the hot air discharge and operating sound level will not annoy the neighbours.
g) The location must not be susceptible to dust or oil mist.

When the pipe length becomes too long, both the capacity and reliability will drop and as the number of
bends increases, system piping resistance to the refrigerant increases, thus lowering the cooling
capacity. As a result the compressor may become defective. Always choose the shortest path and follow the
recommendation as tabulated below:

Maximum Allowable Elevation, m

Equivalent length for various (meter)
Pipe Size L joint Trap bend

1 1/8” (OD 28.58mm) 0.50 3.70
1 3/8” (OD 34.92mm) 0.60 4.40
Notes:
1. Equivalent piping length is obtained with actual length of gas piping.
2. 90° bend of piping is equivalent to L joint.
Bending must be carefully made so as not to crush the pipe. Use a pipe bender to bend a pipe where possible.
For Brazed type, if the piping is less than 7.5m, follow the charge level on serial number sticker. When the
piping is more than 7.5m, use the table below.
