Outdoor unit installation methods
Concrete pad mounting Catwalk mounting
U
H
= Height of outdoor unit (m)
H
t
= Air exhaust duct height (m)
Hu: Height of pad or catwalk (m) H = H
u
+ H
t
(m)
Note: When an air exhaust duct is used, take steps to prevent engine exhaust gas from entering the
heat exchanger, such as extending the exhaust pipe to the same height as the air exhaust duct.

Determine actual installation capacity
(horsepower)
•
Increase mounting height
•
Install an exhaust duct
•
Change to catwalk mounting
•
Change number of units per row, or L
a
Provisional configuration
•
Preliminarily determine average distance L
a
between outdoor units
•
Calculate L
u
, the distance between rows
Will you calculate row length L
N
and external installation dimension L
M
?
Is ambient airflow adequate?
Correct cooling capacity
