Installation - Remote Condenser
Chillers designed for use with a remote air-cooled
condenser include a factory-selected remote
condenser. The remote air-cooled condenser
typically ships separately from a different location
than the chiller.
Location
The remote air-cooled condenser is for outdoor use.
Locate the remote condenser in an accessible area.
The vertical air discharge must be unobstructed.
When locating the condenser it is important to
consider accessibility to the components to allow for
proper maintenance and servicing of the unit. Avoid
locating piping or conduit over the unit to ensure
easy access with an overhead crane or lift to lift out
heavier components during replacement or service.
Proper ventilation is another important
consideration when locating the condenser. In
general, locate the unit in an area that will not rise
above 110°F.
Install the unit on a firm, level base no closer than its
width from walls or other condensers. Avoid
locations near exhaust fans, plumbing vents, flues, or
chimneys. Fasten the mounting legs at their base to
the steel or concrete of the supporting structure. For
units mounted on a roof structure, the steel support
base holding the condenser should be elevated
above the roof and attached to the building.
Avoid areas that can create a “micro-climate” such as
an alcove with east, north, and west walls that can be
significantly warmer than surrounding areas. The
condenser needs to have unrestricted airways so it
can easily move cool air in and heated air away.
Consider locating the condenser where fan noise
and vibration transmission into nearby workspaces is
unlikely.

The clearance requirements are to ensure proper
airflow and to provide space for maintenance. Due
to the nature of their design, the flat coil units
require a minimum of 48 inches all around each
condenser. If two condensers are side-by-side, the
total clearance requirement is 96 inches. For the V-
coil units, the 36-inch clearance at the ends is only
for maintenance access, all of the air entered the
coils from the sides. The clearances shown in the
chart for the V-coils are for ground mounting;
however, if the V-coil units are elevated 12 inches or
more above the ground to allow airflow under the
coils, they can be place 12 inches apart. We
recommend a minimum of 36 inch clear between V-
coil units when elevated the 12 inches or more just
to leave room for maintenance access.
Flat Coil Condenser Foot Mounting
The 10 through 80-ton single-circuit and 20 through
160-ton dual-circuit condensers are a flat or
horizontal coil design and ship on their sides with
the legs removed to reduce shipping dimensions
and provide more protection to the coil from
possible damage caused by impact loading over
rough roads and transit conditions.
Assemble the corner legs to the bottom flanges on
the unit side panels and end panels using the
hardware provided and the matching mounting
hole-patterns. All corner legs are the same. For units
that are longer than three fans, assemble the center
leg. Remove two bolts from the bottom flange of the
unit side panels that match the hole-pattern on the
top flanges of both legs. Attached the center legs
using the hardware provide at the center-divider
panel location. Replace the bolts removed from the
side panels to secure the leg assembly to the bottom
flanges of the condenser side panels.
