INSTALLATION OF THE INDOOR UNIT
The indoor unit must be installed such that there is no short circuit of the cool discharge. Respect the installation clearance. Do
not put the indoor unit where there is direct sunlight on unit. The location must be suitable for piping and drainage and it must
have a large distance between a door and unit.
CEILING CONCEALED MOUNTING
– Use the hanger supplied with the unit.
– Make sure that the ceiling is sufficiently strong to withstand the weight.
Center distance of axle (see drawing below) Provide clearance for servicing ease and optimal air flow as
shown in the diagram.

WATER PIPING CONNECTION
The indoor unit is equipped with water outlet and inlet bare connection. There is an air-vent for air purging that is fitted at the
outlet water header.
3 ways solenoid valve is required for cycling off or bypass the chilled water.
Black steel pipe, polyurethane pipe, PVC pipe and copper tube are recommended in field installation.
All types of piping and connection must be insulated by polyurethane (ARMAFLEX type or equivalent) to avoid condensation.
Do not use contaminated or damaged pipe and fitting for installation.
Some main fitting components are needed in the system to enhance the capacity and ease of service, such as gate valve,
balancing valve, 2 ways or 3 ways solenoid valve, filter, strainer etc.
