4. Close Manual Drain (#19) and Steam Out (#16); turn generator on until Sight Glass
(#10) shows that it is 1/2 full, and then shut off.
5. Insert funnel into coupling, where Safety Valve (#18) used to be.
6. Pour a 1/2 Gallon of hydrochloric acid (inhibited) solution (NON-FOOD
APPLICATIONS) into funnel very slowly, being careful of fumes and venting while
pouring.
NOTE: Solution can be obtained from any industrial chemical dealer.
FOR FOOD APPLICATIONS: Use FDA approved chemicals.
7. Remove funnel, reinstall Safety Valve (#18), and verify Steam Out (#16) is closed; let
solution set in generator for 1 HOUR.
8. Turn on generator, allowing pressure to climb to 5 PSI on Pressure Gauge (#15), and then
shut off.
9. Allow the pressure to drop to 0 PSI on Pressure Gauge (#15) naturally. DO NOT open
Steam Out (#16) or Manual Drain (#19) until pressure is down.
10. Remove Safety Valve (#18).
11. Reinsert funnel, and fill generator completely to the top with clean water; let stand for an
additional 1/2 HOUR.
NOTE: Turning on the generator will not completely fill it to the top. Filling must be done
manually through the safety valve coupling.
12. Open Manual Drain (#19) to drain generator.
13. Close Manual Drain (#19); refill generator completely to the top with clean water and
open Manual Drain (#19) to flush out generator completely.
14. Reinstall Safety Valve (#18) and close Manual Drain (#19).
15. Turn on generator, allowing pressure to climb to 10 to 20 PSI on Pressure Gauge (#15),
and then shut off.
16. “Blow Down” Open Manual Drain (#19) slowly, allowing HOT WATER and STEAM
to blow out into the drain.
NOTE: You may Blow Down your generator at any pressure you feel comfortable with. 10
to 20 PSI is only a recommendation. You may go higher or lower, but higher is always
better.
WARNING – HOT WATER and STEAM under HIGH PRESSURE can lift drain pipes
right off the ground and cause SERIOUS INJURY. Make sure drain pipe is SECURE and
CANNOT move. The drain must be directed into a HIGH TEMPERATURE drain (NO
PVC).
17. Your generator is now ready for normal use and operation.
