NOTE: Don’t place your ngers into the inlet holes of the
casing while moving the unit. Failure to do so may result in
deformation. Only hold the corner of the unit with your hands.
precautIonS for SelectIng a locatIon
1. Choose a place solid enough to bear the weight and
vibration of the unit, where the operating sound will
not be amplied.
2. Choose a location where the hot air discharged
from the unit or the operating sound will not cause a
nuisance to the neighbours of the user.
3. Avoid places near a bedroom and the like, so that the
operating sound will cause no trouble.
4. There must be sufcient spaces for carrying the unit
into and out of the site.
5. There must be sufcient space for air passage and no
obstructions around the air inlet and the air outlet.
6. The site must be free from the possibility of ammable
gas leakage in a nearby place.
7. Do not install the heat pump in the following locations:
(a) Where a mineral oil mist or oil spray or vapor is produced,
for example, in a kitchen.
Plastic parts may deteriorate and fall off and thus may
result in water leakage.
(b) Where corrosive gas, such as sulfurous acid gas, is pro-
duced.
Corroding copper pipes or soldered parts may result in
refrigerant leakage.
(c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the
control system and cause the unit to malfunction.
(d) Where ammable gas may leak, where there is carbon -
ber, or ignitable dust suspension in the air, or where vola-
tile ammables such as thinner or gasoline are handled.
Operating the unit in such conditions may result in a re.
NOTE: Cannot be installed suspended from ceiling or stacked.
precautIonS for InStallatIon
• Check the strength and level of the installation ground
so that the unit will not cause any operating vibration or
noise after installed.
• Fix the unit securely by means of the foundation bolts.
(Prepare 4 sets of foundation bolts (1.5 - 3.0 ton: 3/8”
or 7/16”, 3.5 - 5.0 ton: 1/2”), nuts and washers; all sepa-
rately available.)
• It is best to screw in the foundation bolts until their ends
are 1 inch from the foundation surface.

〈〈Drain treatment〉〉
• In a location where drain from the outdoor unit may cause
troubles (for example, where drainage may splash on
general passersby), perform the drain piping work using
the drain plug (optional).
• For drain treatment, space of at least 4 in. is required
under the bottom frame of the outdoor unit.
• In case of installing the outdoor unit in cold climates, do
not take this centralized drainage way. Otherwise, drain
pipe freeze-up and ice build-up on the bottom frame way
occur.
