RESERVOIR TANK:
The reservoir tank with your Model 400 holds two gallons
of water. The tank is designed to hold the initial water
supply to the boiler and then supply additional water as
the boiler calls for it. When you engage the MAIN power
switch, if the boiler requires water, the reservoir pump
will turn “ON”.
DO NOT
turn on the heater to the boiler
before the pump stops pumping, which indicates that the
boiler is full. The “Blue Light” indicates when the boiler is
calling for more water. This will go on and off during the
time you are using the machine. The reservoir has an air
vent cap, which covers the fill opening; this can be
removed to add more water at any time. This is not a
pressure cap. Do not substitute any other cap. (Shown
with the Yellow Hot Surface Decal). Do not run the pump
dry. Contact Therma-Kleen® for a replacement.
NEVER
use water from a water softener as they use an ion exchange process that
replaces calcium and magnesium minerals in the water with sodium. Sodium can
significantly shorten the lifespan of the boiler system and internal components of you
vapor steam unit.
It is always best to use Distiller Water in your cleaner.
LOW WATER ALARM:
When the tank is out of water and the boiler is almost empty, a low water alarm will
sound to let you know that the heater has shut off and you are out of water. This sensor
protects your heating element
. CAUTION
: never allow the boiler to be “ON” when there
is no water in the boiler. This will overheat and damage the low water sensor and
heating element.
BOILER:
DISTILLED WATER
We recommend that you use distilled water with you steam cleaner. This would
eliminate the possibility of creating hard water stains while you are cleaning and
prevent excessive build-up of mineral deposits around the heating element in the
boiler. If you are using tap water, remember that the life of the heating element
