Installation procedures
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, don’t throw away the attached parts required for the
installation]
• Determine the route to move the unit to the installation site;
• Don’t 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 can’t be jointed, the air can’t 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 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 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.
