General
Data
General
This “Installation Manual” describes
information for condensing units TTK
509 to TTK 536, with horizontal air
discharge, cooling-only, from 9,000 to
36,000 Btu/h.
After unpacking the unit, inspect the
unit for any damage incurred in transit.
Immediately notify the carrier.
Compare the power supply
characteristics with the unit nameplate
data. The power supply must comply
with the unit nameplate data.
All stages of this installation should
comply with local, state and national
codes.
These installation instructions should
be carefully read prior to the air
conditioning system installation.
These instructions are not intended for
all system variations, nor advise
against all situations that may occur
during an installation. If more
information is required, or problems
that avoid client satisfaction arise,
contact your nearest Trane sales office
or Trane.
Unit Location and Preparation
1. The unit should be installed on a
leveled and reinforced concrete
foundation. The minimum height of
the concrete foundation should be
50 mm (1.97”). Unit shall be fixed to
the foundation with bolts (not
supplied).
2. The concrete foundation must be
positioned at least 250 mm (9.84”)
away from any existing wall or
shrubbery.
3. The minimum clearance on the air
inlet sides of the unit should be
250 mm (9.84”), and on the air
discharge side, 1200 mm (47.24”).
4. When the unit is mounted on a roof,
be sure the roof will support the unit
weight. Proper vibration isolation is
recommended in order to prevent
transmissions to the building
structure.
5. Minimum clearances between the
unit and other objects should be
observed in order to assure proper
ventilation.

System Evacuation and Purge
1. The outdoor unit is supplied with
refrigerant pre-loaded in factory . The
load indicated on the nameplate is
the total amount required by a system
with a refrigerant line lenght of up to
7.5 meters (295.3”). Considering that
the outdoor unit does not require
evacuation, except in cases of
refrigerant leakage, the suction and
liquid valves should remain closed.
2. After installation is finished, apply
vacuum in refrigerant lines and indoor
unit.
3. The system should be evacuated until
the vacuum gauge shows a reading
of 350 microns (5.9 x 10-2 inHg).
4. Close the vacuum pump valve, and
observe the vacuum gauge. If the
reading is more than 500 microns
(8.3 x 10-2 inHg) in an interval of one
minute, the evacuation is not
complete, or there is a system
leakage.
5. If the vaccum gauge does not pass
500 microns (8.3 x 10-2 inHg) within
the interval of one minute, the vaccum
is finished.
6. With the vacuum pump off and the
manifold closed, open the service
valves in the liquid and suction lines.

7. Replace the register and valve caps
to prevent leakages.

The refrigerant load will have to be
completed when the distance between
internal and external units is more than
7.5 meters (295.3”). Use table 2 for

Field Installation of the Re-
strictor for Multi-Function
Service Valve (Liquid Line)
Condensing units TTK, are supplied
with a multi-function service valve for
liquid line and a restrictor kit. The use
of the restrictor allows the refrigerant
expansion in installations where the
indoor unit does not have its own ex-
pansion device. The machine is
supplied with a passage orifice in-
stalled at the muti-function valve,
making it adequate for use in conjunc-
tion with indoor units that already have
their own expansion device. For use
with indoor units that does not have
an expansion device, it is necessary
to replace this passage orifice with
one of the restrictor supplied with the
machine.
Step 1. Check in the table below the
restrictor orifice code to be used, ac-
cording to the indoor unit model. The
code is marked on the restrictor body.
Step 2. Isolate the refrigerant circuit,
closing the multi-function service valve
(if the valve is open). Remove the obtu-
rator cover with a 23 mm ( 0.91”)
wrench or other appropriate wrench.
Insert a 5 mm (0.20”) Allen wrench in
the obturator and turn it clockwise until
some resistance is felt. Remove the
flanged nut and the copper cover.
Step 3. Carefully remove passage ori-
fice installed in factory, being careful
not to damage the flare nut thread and
sealing surface between the orifice and
the flare nut.
Step 4. The new restrictor should be
appropriately lubricated and have an o-
ring on the perimeter. The orifice and
the o-ring should be encapsulated in
the valve body seat, and, for that, a
small "crack" should be heard in order
to assure that the orifice was properly
installed. The assembly of these parts
is shown in the figure below:
Step 5. The liquid line tube should be
flanged and burr-free. Clean the tube to
avoid the introduction of dirt or other
strange materials in the refrigerating
circuit and possible damages in the
tube flange while the flanged nut is
tightened.
Step 6. Manually install the flare nut on
the liquid line tube and be sure to apply
the correct torque. Continue the manu-
al assembly on the valve body until a
screwing resistance is felt (metal with
metal). Then, tighten the nut using a
7/8" wrench or other adapted wrench,
according to the flare nut dimensions.
Step 7. Open the valve, turning it coun-
terclockwise (04 turns, or a resistance
is felt), using a 5 mm (0.20”) Allen
wrench.
Step 8. Replace the obturator cover,
manually turning it clockwise by approx.
half-turn.

Electric Connections
1. Important: do not allow electric
wires from the compressor casing
to touch refrigerant tubes or the
compressor.
2. Equipment electric installation and
grounding should be made
according to IEC 335-2-40: 2002
and local codes and/or NEC.
3. The power supply should comply
with the specification in the
equipment nameplate.
4. Install an exclusive overcurrent
protection circuit-breaker for the
outdoor unit. It can also be used for
system protection.
5. Use flexible electric conduits in
cases where vibrations can
introduce noises inside the
structure.
6. Appropriate color electric wires
should be used, for command, to
allow easier connections between
indoor and outdoor units.

System checking before
start-up
1. Make sure that field connections
comply with electric and refrigerant
diagrams for the equipment.
Always refer to Installation and
User Manuals and Engineering or
Service Bulletins provided with the
indoorunits.
2. Check that units are correctly
installed and there is no tool or
debris under or on the units.
3. Check piping and connections for
refrigerant leaks.
4. Check that the unit has a proper
grounding. If there is no grounding at
the site, it is essential to follow
completely this procedure in order to
assure a perfect equipment
operation.
CheckingListforMini-SplitUnitStart-Up
•Verify correctrefrigerant and electric connections

•Insufflation and return grids are free and unobstructed
• Air filters are installed and clean
• Use an inpected thermometer to check if the thermostat is accurate
•Check grounding
•Check forpower voltage,fuse/circuit-breaker ratingsin amperes
• Check that wire sizes are adequate for the power load
• Check all field wiring for tight connection
• Check that electric wires do not touch refrigerant pipes
•Check if remote control batteries are charged
5. Check that voltage is within
specified ratings, and check for
proper circuit-breaker/fuse sizes.
6. Check that electrical wiring is as
specified and connections are tight.
Start the system and carefully
observe the operation. Follow all
