5. Loosen screw and remove black wire
(we will use later)
6. Install wire from terminal 2 of switch
to #1 (where the black wire used to be) |

9. One of the wires is a jumper to #8 (verify)
10. Loosen screw and remove BROWN wire
that does NOT go to #8 (use later)
11. Install wire from terminal 4 of switch
to #3 with brown jumper
12. Tighten screw being sure both wires are
secure

18. Dress 4 wires through top of relay box with all
the other wires. Route away from heat and mount switch.
Replace relay. The two positions are NORMAL OPERATION or
PURGE ONLY. Vehicle Ignition switch has to be on.
19. OPERATION INSTRUCTIONS
This will be a step by step description from running to
cool down. Having arrived from your ride the pressure may
be high enough for the burner to be OFF (approximatly 250
psi).
A. Shut vehicle ignition off
B. Move new switch to the bypass position
C. Turn on ignition switch
D. Bleed off steam until purge fan
comes on (approximatly 175 psi)
E. Allow fan to run for about 5-10
minutes or until the pressure is below 100 psi.
F. At this point all will be cool enough
to be worry free
G. Turn ignition off and move switch
to normal position. |

20. During normal operation the following measurements
were taken at the batteries.
All on with burner firing..........................................20
amps
Purge fan only......................................................13
amps
If installed Small fire eye fan...................................0.3
amps
Based on using 2 Optima SC34DM batteries in
parallel capable of
110 amp hr rating it is estimated that on a full charge
the vehicle should be able to run 8 hours non stop. |
