3-37. Suspending the Indoor Unit
Depending on the ceiling type:
● Insert suspension bolts as shown in Fig. 3-115
or
● Use existing ceiling supports or construct a suitable
support as shown in Fig. 3-116.
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 on the previous page.
(Figs. 3-113a and 3-114a)
Tubing must be laid and connected inside the ceil-
ing 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. 3-115.
(Cut the ceiling material, if necessary.)
(3) Suspend and fix the indoor unit using the 2 hexag-
onal nuts (field supply) and special washers (sup-
plied with the unit) as shown in Fig. 3-117a.
■ RAP (Refrigerant Accumulation Protector)
Valve Kit (EEV22-28)
When installing a ADPS type indoor unit (either the 8-
hp 224 type or 10-hp 280 type), you must also install
the RAP Valve Kit (EEV22-28).
● Connect two RAP valve kits in parallel for 224 or
280 type.
● Secure the R.A.P. valve kit using suspension bolts,
etc. within 30 meters from the indoor unit.
● Do not place the R.A.P. valve kit directly on the
ceiling.
