reGulator Kit straiNer
To ensure proper and consistent steaming results, visu-
ally check the Water Pressure Regulator Gauge and
Strainer Cup regularly. If the pressure on the gauge
has dropped, visually check the clear plastic Strainer
Cup and clean out the accumulated debris as follows.
1. Shut off the water supply valve to the unit,
unscrew the clear plastic Strainer Cup and care-
fully remove the mesh strainer screen.
2. At the sink, gently flush the accumulated debris
from the Strainer Cup and mesh strainer screen
being especially careful not to damage the mesh
strainer screen.
3. Carefully place the mesh strainer screen into its
seat at the bottom of the clear plastic cup and
confirm that the orange O-ring is properly seated
in its place before screwing the Strainer Cup and
top back together.
4. Purge the air out of the strainer and tubing by dis-
connecting the male quick disconnect fitting from
the equipment and, over a bucket, pushing its
valve core in until there is a good water flow.
Monthly
Your Multi-Purpose Steamer utilizes an open steam
generator. When introduced, water immediately vapor-
izes into a burst of steam, leaving behind any minerals
it contained. Though a small amount of minerals are
necessary for proper operation, excessive amounts will
cause poor steaming and may permanently damage the
generator.
Cleaning steam Generator
1. Turn the power off, unplug the power cord, and
allow the unit to cool down before proceeding.
2. Remove the Spatula, Diffuser, and Top Cover
from unit.
Note: the spatula, diffuser, and top Cover must
be removed in this specific order. Failure to do so
may result in damage to the equipment.
3. Examine the generator orifice (hole). If mineral
deposits have formed, place a flat blade screw-
driver into the opening. Use a twisting motion to
scrape openings clean.
Note: if the mineral deposits from the generator
surface come off in “flakes” or in layers, the
mineral build-up is excessive.
