The standard attached accessories of the units of this series refer to the packing; prepare other
accessories according to the requirements of the local installation point of our company.
1. Before installation [before finishing the installation, donít throw away the attached parts required
for the installation]
Determine the route to move the unit to the installation site;
Donít tear the package open before moving the unit to the installation site. When unpacking is
needed, a soft material or protector block with ropes can be used to lift the unit to avoid damaging
or scraping of the unit.
2. Select the installation site
(1) The installation site should be selected according the following conditions, which should be
approved by users.
where an ideal air distribution can be ensured;
where there is no blockage in the air passage;
where the condensed water can be drained out properly;
where the strength can bear the weight of the indoor unit;
where enough space can be ensured for maintenance. The outside air should be input from the
outdoor directly from the blast pipe. If the blast pipe canít be jointed, the air canít be input from
the suspended ceiling.
where the lengths of the piping between indoor units and outdoor units are within the
allowable range (refer to Installation of Outdoor Units)
where the distance of at least 1m between indoor units, outdoor units, mains supply,
connecting wires and television or radio should be kept as to avoid the image disturbance and
noises of the above electrical appliances. (Even if 1m can be ensured, noise might occur if there
is strong electric wave.) Additionally, equipments, television or other valuables canít be put under
the unit as to avoid the condensed water of the unit from dropping into the above articles, causing
damaging.
(2) Height of Ceiling:
The ceiling should be located at the place, where the central position
of air outlet port is less than 3m high above the ground.
