START PERSONNEL HEATER - Continued
1.
Ensure combustion air intake and heater exhaust are clear of obstructions.
2.
Ensure START/OFF/RUN switch (Figure 1, Item 4) on control box (Figure 1, Item 3) is in OFF position.
3.
Press indicator light (Figure 1, Item 2) to see if it glows. If it doesn’t glow, troubleshoot (WP 0087).
NOTE
The heater can be started with the HI/LO switch in HI or LO position. Heater life will be
extended if operated in LO temperature setting.
4.
Set HI/LO switch (Figure 1, Item 1) to desired position for heat control.
5.
Move START/OFF/RUN switch (Figure 1, Item 4) to START position and hold for approximately 4 seconds,
then move switch directly to RUN position. Heater will run automatically.
6.
Wait 3.5 minutes for indicator light (Figure 1, Item 2) to illuminate.
NOTE
•
The Auxiliary Power Unit (APU) may need to be started; turn generator switch to
ON. This will supply enough voltage for heater startup.
•
The fuel pump switch may need to be in ON position to supply more fuel pressure
to heater for startup.
7.
Attempt to restart heater. If heater does not start after three attempts, troubleshoot (WP 0089).
