PREPARATION
1. PREPARATION
1.1 Initial Check
Required Materials – Measure, Architectural
Information Regarding Installation Location.
Installation Location – Confirm that the final
Installation location is provided with convenient
piping and wiring work. Strong water runoff should
be avoided.
Installation Space – Check for obstacles, which
restrict condenser airflow or hamper maintenance
work in the space specified in Fig. 1.
Foundation – Check to ensure that the foundation
is flat, level, and sufficiently strong, taking into
account the maximum foundation gradient (Fig. 2)
and the unit weight balance. Confirm elevation
provision for the unit on a solid base with an iron
frame or concrete curbs shown in Fig. 3, in order
to obtain proper clearance beneath the unit for
either rooftop or on-the-ground installation.
Additionally, for on-the-ground installation, provide
a gravel or concrete space around the condenser
air intake, in order to avoid airflow obstruction due
to grass or other vegetation.
Unit – Check to ensure that the unit has been
transported without damage. File a damage claim
with the transportation companies if mishandling
due to transportation company negligence is
suspected.
1.2 Transportation

confirming the packing dimensions (see "Unit
