EFORE INSTALLATION
■
Decide upon a line of transport.
■
Leave the unit inside its packaging while moving, until reaching
the installation site. Where unpacking is unavoidable, use a sling
of soft material or protective plates together with a rope when
lifting, to avoid damage or scratches to the unit.
■
Caution concerning refrigerant series R-410A:
-
The connectable outdoor units must be designed exclusively
for R-410A.
- If outdoor units for R22, R-407C are connected, the system
will not work properly.
Accessories
Check if the following accessories are included with your unit.
Installation manual, Operation manual
Note to the installer
Be sure to instruct the customer how to properly operate the system
and show him/her the attached operation manual.
S
ELECTING INSTALLATION SITE
1. Select an installation site where the following conditions are
fulfilled and that meets your customer’s approval.
■
Where the ceiling is strong enough to support the weight of
the unit and to prevent vibration and noise generation.
■
Where sufficient clearance for maintenance and service can
be ensured (Refer to
figure 1 : = service space).
The power supply intake (1), drain connection (2), gas pipe
(3) and liquid pipe (4) connection should always be
accessible for maintenance and service.
■
Where piping between indoor and outdoor units is possible
within the allowable limit. (Refer to the installation manual for
the outdoor unit.)
■
There is no danger of fire due to leakage of flammable gas.
■
Ensure that water can not cause any damage to the location
in case it drips out of the unit (e.g. in case of a blocked drain
pipe).
■
Please consult with your dealer for installing in a special
environment (e.g. a place in oily surroundings, a place with
sulfide gas, a place where chemicals are used nearby, a
place with high voltage fluctuations, a place with volatile
flammable gas, a place in which machinery generates
electromagnetic waves.
2. Use suspension bolts for installation. Check whether the ceiling
is strong enough to support the weight of the unit or not.
If there is a risk, reinforce the ceiling before installing the unit.
