Unit Description
16
Engine power for the T-600R, T-800R and T-800R
SPECTRUM is provided by the engine TK370 rated at 15.0
continuous horsepower (11.2 kW) at 2425 RPM.
Engine power for the T-500R is provided by the engine TK270
rated at 10.0 continuous horsepower (7.5 kW) at 2950 RPM. A
belt drive system transfers energy to the compressor, unit fans
and alternator.
ELC (Extended Life Coolant)
ELC (Extended Life Coolant) is standard equipment. The
maintenance interval for ELC is five years or 12,000 hours. A
nameplate on the coolant expansion tank identifies units with
ELC. The new engine coolant, Chevron Extended Life
Coolant, is RED in color instead of the previous GREEN or
BLUE-GREEN colored conventional coolants.
NOTE: The use of 50/50% pre-mixed ELC is recommended
to assure that de-ionized water is being used. If 100% full
strength concentrate is used, de-ionized or distilled water is
recommended instead of tap water to insure the integrity of
the cooling system is maintained.
Clutch
The centrifugal clutch engages fully at 600 ± 100 RPM on
engine operation, constantly turning the compressor, alternator,
and fans at both high and low speed. The clutch isolates the
engine from the belt drive system during electric standby
operation on Model 50 units.
Thermo King Reciprocating
Compressor
The T-500R (w/o bypass oil filter), T-600R, T-800R and 800R
SPECTRUM feature the reliable TK214 four-cylinder
reciprocating compressor. The T-1000R and T-1000R
SPECTRUM feature the reliable TK426 four-cylinder
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.
