3.) CLEANING & MAINTENANCE
The following cleaning procedures are HIGHLY RECOMMENDED in order to keep your
Steam Generator in the best operating condition at all times.
3.1) MANUAL “BLOW DOWN”
A Manual “Blow Down” is an easy way to GREATLY extend the life of your Steam
Generator. Using a Motorized Auto-Flush & Drain (MAFD) of course helps, but is not a “Cure
all”. The following is the LEAST amount of times recommended to blow down your generator:
NORMAL WATER AREAS – Should be done ONCE A WEEK.
BAD WATER AREAS – Should be done ONCE A DAY.
NORMAL WATER AREAS WITH MAFD – Should be done TWICE A MONTH.
BAD WATER AREAS WITH MAFD – Should be done ONCE A WEEK.
NOTE: The best time to Blow Down your generator is after it has been running for some time,
while it is still hot.
1. Place Toggle Switch (#2) and Main Disconnect Box in OFF position.
2. Allow pressure to drop between 10 and 20 PSI.
3. Open Manual Drain (#19) slowly, allowing HOT WATER and STEAM to blow out
into the drain, cleaning out the generator.
NOTE: 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).
3.2) CLEANING WATER LEVEL PROBES
Water Level Probes are the heart of your generator. Almost all steam generator malfunctions
are caused by dirty water level probes. CLEANING your PROBES is by far the MOST
IMPORTANT maintenance step to keep your generator running properly. The following is the
LEAST amount of times recommended to clean your probes:
NORMAL WATER AREAS – Should be done TWICE A YEAR.
BAD WATER AREAS – Should be done 3-4 TIMES A YEAR.
NOTE: The best time to clean your probes is before you turn your generator on, while it is still
cool.
1. Place Toggle Switch (#2) and Main Disconnect Box in OFF position.
2. Make sure generator is cool and the Pressure Gauge (#15) reads 0 PSI.
3. Remove cover plate, exposing the Water Level Probes (#5).
4. Use 5/16” Socket to remove wires from probes.
5. Use 13/16” Spark Plug Socket to remove probes from chamber.
