NOTE
All weights are in lbs.
Units may be either hung or floor mounted. If the unit
is hung, use all the indicated mounting points, whether
the unit is installed as a package or split system (see
Figure 4 on page 13 and Figure 5 on page 14 ).
Hanger rods with a minimum 1/2-inch diameter are
strongly recommended.
Ensure the attachment point of the rods to the build-
ing structure is sufficient to support the unit weight. To
ensure efficient condensate drainage, the unit can be
pitched towards the evaporator end of the unit.
A minimum of 4-inch clearance is required under the
unit to allow for trapping of the evaporator condensate
drain. See Typical Service Clearances on page 20
for more unit clearance information.
SEPARATION OF THE UNITS
All models can be ordered with refrigerant shut-off valves
or couplings. These components allow the evaporator and
condenser sections to ship factory-split. The evaporator
and condenser can then be assembled onsite without re-
quiring the entire unit refrigerant charge be reclaimed.
The 2–5 ton models are available with shut-off valves.
The 8 and 10 ton models are available with self-sealing
brass refrigerant couplings. A field-split coupling kit
is available for field-split applications of 8 and 10 ton
models ordered with couplings. Refer to General Piping
Recommendations and Refrigerant Line Lengths ( Form
247077-UAD-H-0209 ) .
The male coupling is fastened to the condenser wall via a
mounting bracket. The 8 ton unit ordered as a single pack-
aged unit can be field split. To separate the couplings with-
out stressing the refrigerant piping, use a backup wrench
on the female coupling (see
Figure 3 on page 12
).
