1. Before installation [Don’t throw away the attached parts required for the installation]
Determine the route to move the unit to the installation site;
Transport the unit in it's box to prevent damage.
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 structure can bear the weight of the indoor unit;
where enough space can be ensured for maintenance.
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 3.28ft (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 3.28ft (1m) can
be ensured, noise might occur if there is strong electric wave.)
Additionally, equipments, television or other valuables can’t 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 9.84ft (3m) high
above the ground.
(3) Hoisting studs should be used during installation.
Check if the location can bear the weight of the unit.
Reinforce it before installation if necessary.
