Unit Description

Engine
Engine power for the SPECTRUM
™
TS is
provided by a three cylinder, special clean and
silent diesel engine. A belt drive system transfers
energy to the compressor, unit fans and alternator.
In the first quarter of 2006 the engines in these
units changed from a TK 3.95 to a TK376 to meet
EPA Tier 2 requirements.
The TK 3.95 is an EPA Tier 1 engine. It is a
three-cylinder diesel engine rated at 17.0
continuous horsepower (12.7 kW) at 2400 rpm.
The TK376 is an EPA Tier 2 engine. It is a
three-cylinder diesel engine rated at 19.6
maximum horsepower (14.6 kW) at 2425 rpm.
The most noticeable difference is that the valve
cover and intake manifold are separate on the
TK 3.95, but are an assembly on the TK376 (see
the following illustrations). There are other
differences, but the periodic maintenance is
basically the same. See “Maintenance Inspection
Schedule” on page 25.

Clutch
The centrifugal clutch engages fully at 600 ± 100
rpm on engine operation, constantly turning the
compressor and alternator at both high and low
speed. The clutch isolates the engine from the belt
drive system during electric standby operation on
Model 50 units.
ELC (Extended Life Coolant)
ELC (Extended Life Coolant) is standard in these
units. The maintenance interval for ELC is five
years or 12,000 hours. A nameplate on the coolant
expansion tank identifies units with ELC. See
“ELC (Extended Life Coolant)” on page 96. The
new engine coolant, Texaco Extended Life
Coolant, is RED instead of the previous GREEN
or BLUE-GREEN conventional coolants.
ELC cannot be used in older units. The water
pump seal bellows and O-rings used in older units
are not compatible with ELC.
CAUTION: Do not add Green or
Blue-Green, conventional coolant to
cooling systems using Red, Extended Life
Coolant, except in an emergency. If
conventional coolant is added to Extended
Life Coolant, the coolant must be changed
after 2 years instead of 5 years.
