can be made by increasing the supply pressure. Consult
your TDI distributor for advice.
Exhaust piping should be routed downward to help
prevent any accumulation of condensation in the starter
motor.
If the overhung section of the starter is not otherwise
supported, TDI recommends that the exhaust piping be
supported with a suitable bracket(s).
3.4 SOFT START VALVE & FILTER FITTING
The “soft start” fitting (P/N: 2-28243), by providing a
slower opening of the starter relay valve, eliminates
excessive starter pinion gear loading. The soft start
fitting is identified by the mark “EL-SOFT START” found
on its body. This fitting MUST be installed at the starter
relay valve as shown in figure 4. It is screwed into the
applied pressure (“IN” or “APP”) port on the starter relay
valve. There are currently no approved substitutions for
this fitting.
The filter fitting (P/N: 2-28270) provides contamination
protection to the starter’s pre-engagement mechanism
and the soft start fitting installed downstream. The filter
fitting is to be installed on the “IN” port of the starter as
shown in figure 4. It appears similar to the soft start
fitting, however, there are no identifying marks on the
filter fitting.
For multiple starter applications, a soft start fitting must
be installed on EACH relay valve and a filter fitting must
be installed on EACH starter as shown in figure 5.
CAUTION
For maximum pinion life and full warranty coverage,
the soft start valve (P/N: 2-28243) MUST be installed
in the applied pressure port (APP) of the relay valve.
3.5 NATURAL GAS INSTALLATION
The installation of the starter using natural gas is similar
to the air installation except all fittings, piping, valves and
regulators must be compatible with natural gas.
Proper control of natural gas is a major consideration
when used in the starter system.All starters using
natural gas must pipe the exhaust according to industry
codes and local regulations.
There is a natural gas vent port in the turbine housing
that is plugged for compressed air use. This vent is used
to remove any natural gas that could leak past the
primary turbine shaft seal. Remove this 3/8"NPT plug
and install a line to carry gas away from the starter area.
WARNING
Do not connect the turbine housing vent line to the
turbine exhaust line. Exhaust gas can pressurize the
turbine housing.
3.6 PIPING SYSTEM
Only type approved metallic hose assemblies are
approved in permanently pressurized compressed air
lines of starters. Non-metallic hose assemblies are
allowed only in case the piping system will be emptied
after the starting procedure.
Pipe unions must be type approved by GL. Downstream
of the pressure regulator a pressure relief valve is to be
provided.
4.0 STARTER OPERATION
Prior to operation, check that all connections are tight
and free from leaks. Check the 1/4" NPT pipe plug or a
pressure gauge/transducer that may be connected to the
pressure port on the starter inlet.
WARNING
Do not operate the TDI T

starter with air
pressure greater than the pressure rating on the
nameplate. This pressure is measured at the starter
inlet while the starter is running.
The maximum operating pressure limit is the inlet
pressure measured at the starter’s inlet pressure check
port. In order to check the starter, a 1/4"NPT pipe tap
connection is provided in the inlet housing to attach a
pressure gauge/transducer). The maximum pressure
assumes an open exhaust (the standard turbine exhaust
guard). The standard exhaust guard causes no back
pressure.
The static non-flowing supply pressure will always be
higher than the operating (dynamic) pressure. The
maximum pressure limit (proof pressure) that the T100-V
starter housings may be subjected to is 600 PSIG (42
BAR). System pressure that exceeds the maximum
operating limit must use a pressure reducing device to
ensure that the operating pressure limit to the T100-V
starter is maintained.
System static pressure that exceeds the 600 PSIG (42
BAR) limit must, in addition to pressure reducer devices,
