3-20. Suspending the Indoor Unit
Depending on the ceiling type:
●Insert suspension bolts as shown in Fig.
●Use existing ceiling supports or construct a suitable support as shown in Fig.
WARNING | It is important that you use extreme care | |
in supporting the indoor unit inside the | ||
| ||
| ||
| ceiling. Ensure that the ceiling is strong | |
| enough to suport the weight of the unit. | |
| Before hanging the unit, test the strength | |
| of each attached suspension bolt. |
(1)When placing the unit inside the ceiling, determine the pitch of the suspension bolts referring to the dimensional data given previously. (Figs.
DTubing must be laid and connected inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the tubing into position for connection to the unit before placing the unit inside the ceiling.
(2)Screw in the suspension bolts allowing them to protrude from the ceiling as shown in Fig.
(3)Suspend and fix the indoor unit using the 2 hexagonal nuts (field supply) and special washers (supplied with the unit) as shown in Fig.
