Additional Location Requirements
for Remote Evaporator Only
The remote evaporator must be
installed indoors, unless:
– ambient temperatures are always
above 32 F.
– the system circulating liquid is a non-
freezing glycol-type solution, selected
for the prevailing ambient
temperatures.
– the evaporator is protected from
freezing by properly installed and
applied insulation and heat tape.
Caution: To prevent internal
damage due to freezing, do not
install the outdoor unit without
adequate...

Rigging
The Model RTAA chiller should be
moved by lifting. Refer to Figures 14
thru 17 for typical unit lifting and
operating weights. Refer to the rigging
diagram that ships with each unit for
specific “per unit” weight data.
WARNING: To prevent injury or
death and unit damage, capacity
of lifting equipment must exceed
unit lifting weight by an
adequate safety factor.
Lifting Procedure
Caution: To prevent damage do not use
a forklift to lift the unit.
[ ] Install clevis connectors through...

Unit Isolation and
Leveling
For additional reduction of sound and
vibration, use one of the two mounting
methods outlined below:
1. Construct an isolated concrete pad
for the unit or provide concrete
footings at each of the eight unit
mounting points. Mount the unit
directly to the concrete pads or
footings. Level the unit using the
base rail as a reference. The unit
must be level within 1/4 over the
entire length. Use shims as
necessary to level the unit.
2. Install the optional spring...
