1. Check the battery voltage is at full charge.

2. Check at unit adaptor that voltage at unit is greater than 11.6V

3. Check that the cables sq.mm suffice for power transfer

4. Ensure all fuses are intact, breakers closed, connections are tight.

5. Check no oxygenation on fuses, breakers connections etc,

6. Check fuel in tank, check filter and pipe has fuel (none inland water only)

7. Ensure exhaust outlet is free of obstruction/ if shut open it

8. Switch unit on and listen for pump pulse clicking. Allow to prime.

9. Does the yellow LED light up at start up, if so is it steady?

10. Does the YELLOW LED light up but then BLINK  refer to 1,2,3 above

11. Does RED and YELLOW flash together? LOCK out, reset unit

12. If no LED displayed, refer to step 4 and 5.

         (At start up only the YELLOW LED is on, if both flash then unit is in SAFETY  lockout.

           THE UNIT MUST BE CHECKED prior to restart)

13. Are the cables direct from the battery to the unit (fused)

14. Are they via a 12 volt distribution system

15. If fed from 12 volt distribution, what size cable from battery to distribution?

16. If fed from 12 volt distribution, how far is unit from distribution board?

17. What volts at the Distribution switch/fuse out let?

 (Guide:- measure on + ve red and across to common neutral  with unit switched on)

18. Are there any connections/ joints in the cable supply to the hob?

19. Are all joints/terminals /contacts in the cable supply secure in their holders.

20. Is the cable 4 sq mm (AWG10) or greater.

   (From battery to unit is 4metres=4 sq mm, if length is 6metres= 6 sq. mm)

21. Do the cables feed any other units or utilities? (If yes how many and what)

  (Each unit must have its own dedicated cable)

______________________________________________________

22. Is the fuel supply direct from the tank?

23. Is the supply fed from top or bottom of tank?

24. If from TOP of tank, is the dip tube Wallas (Pt. No 30011)?

25.  If NOT, State otherwise and size of bore.

26.  Is the tank full fuel level higher than the unit?

27. If YES, is there a solenoid valve fitted to the fuel supply?

28. Are there any other devices being fed from Wallas dedicated fuel line?

29. Are there any fuel filters on the fuel line, if so what type?

30. Is the fuel line copper (Pt No 300692) 1/8” OD

31. Is the fuel line Wallas clear plastic (Pt No. 11010) 5OD / 2ID

32. What is the internal bore? And total length from tank?

           (For fuel, maximum operable length is 8metres and max bore of 2mm)

33. How many connections are on the fuel line from the tank to the hob?

34. Are the connections tight, with insert (740120) fitted in ALL plastic connectors.

35. Can you hear the pump pulsing loudly at start up?

     (Loud click from pump may be indicative of air ingress see items 23 & 24 above)

36. During light up period are there any other LED signals showing after a period of 3 to 4.5 minutes, if YES what are they? In what sequence

(Normal condition, RED LED on steady, YELLOW on steady, heat on hob)
