6. Place a clean container under bleed valve (1) then slightly open valve.
7. Fill expansion tank (17) until thermal fluid starts draining from bleed valve (1).
8. Close bleed valve (1).
9. Thread dipstick (16) into fill port (14) hand tight.
10. Unthread dipstick (16) and check for thermal fluid on dipstick. If thermal fluid level is between full marks (18)
continue to step 12, otherwise continue to step 11.
11. Add thermal fluid to expansion tank (17) stopping periodically to check level. When fluid level is at full marks
(18) continue to step 12.
12. Thread dipstick (16) into fill port (14) hand tight.
13. Use maintenance menu to start thermal fluid pump (WP 0010 00). Allow thermal fluid to circulate for
approximately fifteen minutes then stop thermal fluid pump. Check for leaks while thermal fluid is circulating.
14. Unthread dipstick (16) and check for thermal fluid on dipstick. If thermal fluid level is between full marks (18)
continue to step 15, otherwise repeat steps 11 through 13.
15. Apply pipe thread sealant to threads of dip stick (16).
16. Thread dipstick (16) into fill port (14) by hand tight then tighten 1/2 turn.
