Installation
condensation coils must be
protected from side winds when
their speed exceeds 16 km/h.
Position the unit above the average
height of snow observed in the
region where it is installed. Never
install temporary or permanent
objects (tarp or roof) over the unit,
because recycling of hot air would
reduce the capacity of the
condensation coils. Discharged air
from the fans must not be
obstructed. It is prohibited to install
ducts for the fan discharge air (even
short ones). This is because the fans
supplied on standard units do not
generate any additional static
pressure.
Clearances
Provide enough space around the
unit to allow the installation and
maintenance personnel unrestricted
access to all service points. Refer to

dimensions and recommended
clearances. Unobstructed flow of
condenser air is essential to maintain
chiller capacity and operating
efficiency.
Note for RTCA: When determining
unit placement, give careful
consideration to ensuring a sufficient
flow of air across the condenser
heat-transfer surface.
