This manual describes installation,
operation, and maintenance of
RTAC units, manufactured in
Charmes, France.
A separate manual is available for
the use and maintenance of the
unit’s controls – TracerTM CH.530.
Unit Inspection
On arrival, inspect the unit before
signing the delivery note. Specify
any visible damage on the delivery
note, and send a registered letter of
protest to the last carrier of the
goods within 72 hours of delivery.
Notify the local TRANE sales office
at the same time. The delivery note
must be clearly signed and
countersigned by the driver. Any
concealed damage shall be notified
by a registered letter of protest to
the last carrier of the goods within
72 hours of delivery. Notify the local
TRANE sales office at the same time.
Important notice: No shipping
claims will be accepted by TRANE if
the above mentioned procedure is
not respected.
Note: More stringent national rules
can apply in some countries.
For more information, refer to the
general sales conditions of your
local TRANE sales office.
Loose Parts Inventory
Check all the accessories and loose
parts that are shipped with the unit
against the shipping list. Included in
these items will be water vessel
drain plugs, rigging and electrical
diagrams, and service literature,
which are placed inside the control
panel and/or starter panel for
shipment.

Installation
Responsibilities
Generally, the contractor must do
the following when installing an
RTAC unit:
[ ] Install the unit on a flat
foundation, level (within 1/4"
[6 mm] across the length and
width of the unit), and strong
enough to support unit loading.
[ ] Install the unit per the
instructions contained in the
Installation-Mechanical and
Installation-Electrical sections of
this manual.
[ ] Make electrical connections at
the CH.530.
[ ] Where specified, provide and
install valves in the water piping
upstream and downstream of the
evaporator water connections, to
isolate the evaporator for
maintenance and to balance and
trim the system.
[ ] Furnish and install a flow proving
device and/or auxiliary contacts
to prove chilled-water flow.
[ ] Furnish and install pressure
gauges in the inlet and outlet
piping of the evaporator.
[ ] Furnish and install a drain valve
to the bottom of the evaporator
water box.
[ ] Supply and install a vent cock to
the top of the evaporator water
box.
[ ] Furnish and install strainers
ahead of all pumps and
automatic modulating valves.
[ ] Provide and install field wiring.
[ ] Install heat tape and insulate the
chilled-water lines and any other
portions of the system, as
required, to prevent sweating
under normal operating
conditions or freezing during
low-ambient temperature
conditions.
[ ] Start the unit under the
supervision of a qualified service
technician.
Storage
Extended storage of the unit prior to
installation requires the following
precautionary measures:
1. Store the unit in a secure area.
2. At least every three months
(quarterly), check the pressure in
the refrigerant circuits to verify
that the refrigerant charge is
intact. If it is not, contact the
appropriate sales office.
3. Close the optional discharge and
liquid-line isolation valves.

CAUTION
4.This unit must be lifted with the
utmost care. Avoid shock load by
lifting slowly and evenly.
Special Lifting and Moving
Instructions
A specific lifting method is
recommended as follows:
1. Lifting points are built into the
unit. (There are four lifting points
for RTAC 120-200, and eight
lifting points for RTAC 230-400.)
2. Slings and spreader bar to be
provided by rigger and attached
to the lifting points.
3. Minimum rated lifting capacity
(vertical) of each sling and
spreader bar shall be no less than
the tabulated unit shipping
weight.
