Installation Requirements - Trane RTAF SE Series Installation Operation & Maintenance

Installation Requirements

Installation Responsibilities
Generally contractor must do following items when
installing an RTAF unit;
1. Install the unit in a fl at foundation, level and strong
enough to support unit loading.
2. Install the units as per instructions contained in this
manual.
3. Make electrical connections of the Tracer UC800.
4. Where specifi ed, 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.
5. Furnish and install a water fl ow prove device and/or
auxiliary contacts to prove chiller water fl ow.
6. Furnish and install water pressure gauges in the inlet
and outlet of the evaporator water box.
7. Supply and install an air vent cock to the top of the
evaporator water box.
8. Furnish and install strainers ahead of all pumps and
automatic modulating valves.
9. Provide and install fi eld wiring.
10. Install heat tape and insulate the chilled water lines
and any other portion of the system, as required, to
prevent sweating under normal operating conditions
or freezing during low ambient temperature
conditions.
11. Ensure that the compressor and oil separator
heaters have been operating for a minimum of
24 hours before starting. Failure to do so may
result in equipment damage.
12. Start the unit under supervision of a qualifi ed service
technician.
Storage
Extended storage of the unit prior to the installation
requires the following precautions:
1. Store the unit in a secured area, to avoid intentional
damages.
2. Close the suction, discharge and liquid-line isolation
valves.
3. At least every three months, connect a gauge and
manually check the pressure in the refrigerant circuit.
If the refrigerant pressure is below 13 Bar at 20°C (or
10 Bar at 10°C), call a qualifi ed service organization
and the appropriate Trane sales offi ce.
Note: If the unit is stored before servicing near a
construction site it is highly recommended to protect
micro-channel coils from any concrete dust. Failure to
do so may considerably reduce reliability of the unit.

Lifting and Moving Instructions
A specifi c lifting method is recommended, which can be
described as follow:
1. Lifting points are built into the unit, see lifting
instruction label on the unit.
2. Slings and spreader bar must be provided by crane
operator and attached on the lifting points.
3. Use the four rigging points which are built into the
unit.
4. The minimum lifting capacity of each sling as well as
the spreader bar must be higher than the tabulated
unit shipping weight.
5. CAUTION! Lift and handle with care. Avoid shocks
while handling.
Figure 1 – Lifting
Dimension and Weights
See lifting weight on the submittal on the unit for
complete information.
Center of Gravity
See instructions on lifting drawings available on request.
WARNING! Heavy Objects!
Ensure that all the lifting equipment used is properly
rated for weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to lift
the unit must be capable of supporting the entire weight
of unit. Lifting cables (chains or slings) may not be the
same length. Adjust as necessary for even unit lift. Other
lifting arrangements could cause equipment or property
damage. Failure to follow instructions above or properly
lift unit could result in unit dropping and possibly
crushing operator/technician which could result in death
or serious injury.
WARNING! Improper Unit Lift!
Test lift unit approximately 10 cm to verify proper center
of gravity lift point. To avoid dropping of unit, reposition
lifting point if unit is not level. Failure to properly lift
unit could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury and possible equipment or property- only
damage.
