Block Heaters; Emergency Stop Kits - Kohler 48RCLC Installation Manual

6.3 Block Heaters

Block heaters are available as loose accessories. Use block heaters on standby applications where the generator set is
frequently subjected to temperatures below 0º C (32º F).
The generator set engine is equipped with valves that eliminate the need to drain the cooling system before installing the block
heater. Refer to the installation instructions provided with the block heater kit.
Connect the block heater to a power source that is energized when the generator set is not running.
Note:
Block Heater Damage. The block heater will fail if the energized heater element is not immersed in coolant. Fill the cooling
system before turning on the block heater. Run the engine until it is warm, and refill the radiator to purge the air from the system
before energizing the block heater.
Note:
Route hose under engine. Rotate fitting to
keep hose away from exhaust pipe

6.4 Emergency Stop Kits

The emergency stop (E-stop) switch allows immediate shutdown of the generator set from a remote location. The E-stop
assembly includes a shroud that allows the installation of a lockout/tagout device to lock the switch in the stop position. See
Figure 32. Mount the emergency stop switch(es) outside of the generator set enclosure, in accordance with NEC requirements.
When the emergency stop switch is activated, contacts in the switch open to shut down the generator set. Connect as many
emergencies stop switches as required. Connect multiple switches in series to ensure that activating any one of the stop switches
will stop the generator set.
