Chamber Treatment Instructions:
1. Turn on generator, allowing pressure to climb to 10 to 20 PSI on Pressure Gauge (#15),
and then shut off.
2. “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).
3. Remove Safety Valve (#18).
WARNING – There MUST be NO PRESSURE in the chamber when removing the Safety
Valve (#18), make sure the steam out and drain are open to assure chamber will remain
depressurized. Be cautious of escaping steam from chamber while Safety Valve (#18) is
removed.
