Selection of installation positions for indoor unit

be installed towards the top of the room to ensure highest temperature air isrned to the indoor unit (optimising efficiency)

be installed at the position where the air delivered from the unit can reach everyer of the room

avoid bloc!age to the air inlet or outlet of the unit

to install on top of electronic e#uipment due to ris! of lea!age of condenseder in the case of drain pipe bloc!agee case of modular redundant system installation (i%e% more than 1 unit installed) & ta!en to ensure that all units will be more or less e#ually e'posed to the heat

rces and able to direct their airflow to the telecom e#uipment inlets%

1 Ensure sucient space for installationand maintenance.

allow ease of maintenance and optimum performance it is recommended toure enough space between the unit and the walls%ention: If there are some additional devices to install to the air conditioner (such asBCU) !e sure add to the installation s"ace for these devices#

2 Height limits of indoor and outdoor units.acceptable for the indoor unit to be located above or below the outdoor unit up to aimum of m (see below)%

to avoid bending the piping lines e'cessively so as to avoid possible negative impactn the performance of the units%e *2012

Selection of installation positions for outdoorunit

all the outdoor unit in a position which can stand the load of the machine weightwhich will not cause e'cessive vibrations and noise

all the unit in a well ventilated location not e'posed to rain or direct sunshine

ere the noises generated from the unit will not affect the neighboring placesnot install the unit on a non-metal framenot install the unit in places where there is ris! of e'posure to inflammable gasesattention to the drainage of the condensed water from the base plate during
