Installation
For minimum clearance, consult
the certified submittals, which are
available on request from your Trane
Sales Office.
Unit nameplate
The unit nameplate gives the
complete model reference numbers.
The unit power rating is shown, and
power supplies should not deviate by
more than 5 % from the rated power.
Compressor motor amperage is
shown in box I.MAX.
The customer’s electrical installation
must be able to withstand this
current.
Installation instructions
Foundations
No special foundations are required,
provided the supporting surface is
flat and level, and can withstand the
weight or the unit.
Anti-vibration rubber pads
They are supplied as standard with
the machine, and should be placed
between the supporting floor and the
unit to attenuate vibrations.
- 4 pads for the sizes 190 to 300
- 6 pads for the sizes 350 to 800
- Trane does not allow the
installation of spring isolators.
Clearance
Respect recommended clearance
around the unit to allow
maintenance operation to take
place without obstruction and
recommended clearance around
condenser.
CAUTION! Unit operation depends
on the air temperature. Any recycling
of the air fed out by the fans will
increase the air intake temperature
over the condenser fins and can
result in high pressure cut-out.
In this case the standard operating
conditions are modified.
Operation of the unit may be
affected by an increase in air
temperature on the condenser.
When the units are positioned in a
windy area, avoid all the risks of aircooled recycling.

Installation
Discharge lines
Discharge lines should be calculated
to obtain the gas displacement
speed in horizontal and vertical lines
required to drive compressor oil.
Determine diameter of discharge
lines as per the following criteria.
1. Speed above 2.5 m/s horizontally.
(Consider minimum speed at
minimum load)
2. Speed above 5.0 m/s vertically
(Vertical risers, consider speed at
minimum load)
3. Maximum speed 20 m/s.
4. Horizontal pipe run must be
pitched of 1cm/m in the same
direction as the refrigerant
circulation
5. An oil trap is necessary for vertical
risers greater than 3m. For major
elevations add an intermediate oil
trap every 5m.
6. Maximum pressure drop between
20 to 50 kPa
7. Install a filter drier adapted to
refrigerant capacity.
Insulation of refrigerant lines
Insulate refrigerant lines from
building itself to avoid transmission
to building structure of vibrations
normally caused by pipework.
Also avoid bypassing the unit’s
damping system by fixing the
refrigerant lines or the electrical
ducts very rigidly.Vibrations may
propagate into building structure
through rigidly fixed refrigerant lines.

3 = Subcooler coil
4 = Schraeder valve
5 = Coil header
6 = Relief valve
7 = High pressure switch
8 = Low pressure transducer
9 = High pressure transducer
10 = Stop valve
Calculating and fixing the capacity
of refrigerant lines is necessary
to assure the oil return to the
compressor, avoid refrigerant phase
changes and limit pressure drop.
Liquid lines
Calculate capacity of liquid line, as
per the following criteria.
1. Maximum load operating
conditions.
2. To avoid any evaporation risk:
- Consider the vertical risers
- Maximum pressure drop must not
exceed 1 to 2°C
3. Liquid circulation speed in a 0.5 to
2m/s range.
Pressure tests. Leak detection
During operations, take the following
precaution:
1. Neither oxygen nor acethylene
should be used instead of
refrigerant and nitrogen to
detect leaks, otherwise a violent
explosion may occur.
2. Always use valves and
manometers to check the test
pressure in system. Excessive
pressure may either cause pipes
to rupture, damage unit, or cause
an explosion, causing possible
physical injury.
Carry out liquid line and hot gas line
pressure tests in accordance with
current standards.
The test pressures applied to the
liquid line and the hot gas suction
line must comply with the country’s
standards.
Caution: Do not go more than 0.7
bar above the high pressure switch
setpoint.
7RAU-SVX01F-E4
Installation
Introduce enough refrigerant into
circuit in order to obtain a pressure
of 85 to 100 kPa. Search for possible
leaks using detector. This operation
should be carried out with great care
throughout the system.
If leaks are detected, pump down
the refrigerant, and repair defective
component. Repeat test process, to
check that the repair can withstand
rated pressure.
Refrigerant charge
(all split system types)
Units ship with a nitrogen holding
charge and isolating valves.
After system pressure and vacuum
testing, fill up unit with refrigerant.
The refrigerant complement will be
charged according to the diameter
and the length of the refrigerant
piping work up to obtain the
correct superheat and subcooling
temperatures.
Oil charge
The oil quantity necessary for the
split system has also to be adjusted
according to the diameter and the
length of the refrigerant piping work.
Important note: These operations
have to be performed by a specialist
according to the rules of the art. The
results have to be written on a start
up record by the Trane engineer
or the client’s specialist who has
performed this start up. The quantity
of refrigerant and oil added are at the
client’s charges.
