PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS
COLD WEATHER SET-UP OPERATION UNDER UNUSUAL CONDITIONS
3. Start the diesel fuel-fired heater as follows (see Figure 11):
NOTE
The heater cannot be started until electrical power is established. Start the heater
as soon as electrical power is established.
a. Establish electrical power to the TWPS. Refer to Refer to WP 0012, Establishing
Electrical Power.
b. Check the fuel level in the diesel heater. Add fuel as needed.
c. Make sure the power switch on the heater electrical panel is in the OFF position.
d. If the remote thermostat is used, set the thermostat toggle switch on the heater electrical
panel to the ON position. Then set the dial on the remote thermostat to 70 degrees F.
e. If you are not using the remote thermostat, set the thermostat toggle switch on the heater
electrical panel to the OFF position. This will cause the heater to operate continuously
once it is started.
f. Move the power switch on the heater electrical panel to the ON position. The heater
should start up immediately (unless the remote thermostat is used and is set at a lower
temperature than the surrounding air).
NOTE
If the heater should fail to ignite, or if the flame goes out during operation, the
safety control will shut off all power to the heater and render the heater inoperable.
The heater will automatically try to restart in 120 seconds.
After three
unsuccessful automatic restart attempts, the safety control will lock out. If this
occurs, refer to the cold weather troubleshooting procedures in WP 0033,
Operator/Crew Troubleshooting Procedures.
