1. Perform work, taking care with the followings:
Be sure to check the combination pattern of indoor and outdoor units and joints to be used (Table 2).
Be sure to observe the limits to refrigerant pipe length and number of bends (Table 1).
Insert the refrigerant pipe (procured at local site) and joint into the expanded pipe portions of distributing pipe
(this product) until they stop, and then connect them using anti-oxidization soldering.
There is no restriction on the orientation of distributing pipe (this product)during installation.
Take care that no foreign object, such as dust, enters during pipe connecting work.
Remove the tag of liquid pipe after checking it.
2. Pipe connections
The provided joints will be necessary depending on the capability of model used: See (Table 2), and connect
ޓthe joints as shown in (Fig. 2).
Do not bend or widen the distributing pipe (liquid pipe).
