Operation
With all power disconnected at main switch, insure all electrical and
mechanical connections are tight before energizing unit to prevent electrical
problems and mechanical leaks.
1.
Turn on water and electrical supply, power and control voltage suppliers.Turn unit switch to ON position; Switch light
will go ON and water level will reach operating level automatically.
2.
When proper operating level is reached (approximately half way up the gauge glass), the heating element(s) will be
energized. In approximately 20 minutes, steam will begin to be produced.
3.
Adjust the
F1
Plus operating temperature control to the desired steam room setting at the sensor
(range 100°F – 120° F). Operating temperature is at the discretion of the owner/operator.
For user comfort, the F1 Plus operating control is provided with an adjustable
temperature range. The F1 Plus control will cycle automatically to maintain
the room operating temperature selected by the owner/operator at the sensor at the set
point temperature.
4.
If not supplied with an automatic blowdown system, the generator must be blown manually down daily. An optional
automatic blowdown assembly is recommended for daily maintenance. The steambath generator should be blown
down manually in accordance with manual blowdown instructions below. See below.
Blowdown is an essential part of operation. It is an excellent preventative maintenance procedure and will prolong steam-
bath generator operation. Insure the following recommended blowdown schedule is established and followed daily:
1.
If blowdown is conducted manually, at the end of each working day while unit is still operating,
turn ON/OFF switch to the "OFF" position and close water supply valve. De-energize wall-mounted safety switch.
Open blowdown valve(s) SLOWLY.
IMPORTANT:
Pressure may still be in the generator.
2.
Discharge is complete when gauge glass shows no water. Unit has been effectively drained. Follow this
procedure:
a. Fully close the blowdown valve
b. Fully open water supply
c. Put ON/OFF switch in the "ON" position
d. Close wall-mounted safety switch
3.
When re-filling is complete (water feed solenoid valve de-energizes and water is visible to half-way level in gauge
glass), turn off generator unless further operation is required.
4.
If you have been supplied with a manual reset low water control, as required by some states, the reset button on the
control must be reset before unit will begin developing pressure. Do not push reset until unit has filled with water.
5.
More frequent blowdowns may be required in area with hard water or excessive usage. Please consult with factory.
Automatic Blowdown Systems drain the steambath generator every 24 hours (or more often if required or desired). It
also turns the generator "ON" and "OFF". Blowdown occurs after the timer turns the generator off. The blowdown pilot
light is energized during blowdown.To set the timer, refer to instructions on inside of element access door.
Use of chemical cleaning compounds voids warranty.
To provide for safe and low temperature blowdown, and to comply with
National and local plumbing and building Codes, it may be necessary to blow-
down into an ASME Code blowdown separator tank, or to take other precautions to prevent
damage to building drain plumbing. Consult with a licensed plumber.
