IMPORTANT NOTE: As you follow these instructions, you will notice
warning and caution symbols. This information is important for the safe
and efficient installation and operation of this generator. These are types
of potential hazards that may occur during this installation and operation:
FUNCTIONALITY OF THE TIMESWITCH
The countdown timer uses a relay to switch the steam
solenoid on. During the preset running time, the relay
energizes and activates the connected steam solenoid
by closing a circuit. After the time has elapsed, the
relay deenergizes and deactivates the connected steam
solenoid by opening the circuit again. THE TIMER MAY
ONLY BE OPERATED AFTER INSTALLATION IN A
PROTECTIVE HOUSING. A large 3-digit LCD display is
provided for monitoring the countdown of the timer.
BEFORE USE
Before installing and using this timer, it is absolutely nec-
essary that you read this operating manual thoroughly.
SAFETY INSTRUCTIONS
This timer may only be installed by a qualified, licensed
electrician and must be installed in accordance with
National and local codes.
SHOCK HAZARD! Install the timer per
these instructions before connecting to the main supply.
Never touch live contacts or components.
Protection from contact with the line volt-
age components must be achieved by proper installa-
tion in a 4 x 4 junction box. When installing the timer,
ensure the fastening sliders prevent the timer from being
removed.
DO NOT install the timer in a wet or damp
location.
DO NOT install the timer inside the steam
room.

3. STEAM VENT
IMPORTANT: A steam vent (PN 104072) must be installed
in the steam line between the steam generator and the
steam solenoid valve when using a 30 minute timer as shown.
The steam vent will release hydrostatic pressure in the boiler
while filling when the 30 minute timer has timed out.
Make sure the boiler and pipes are not hot and
have no pressure before installing the steam vent.
1. The steam vent shall be plumbed into a Tee in the steam
line between the boiler and the solenoid valve. Only one
steam vent is required, even if the boiler services two
rooms.
2. IMPORTANT NOTE: The steam vent should remain
accessible for service.
3. The steam vent should
be oriented vertically,
with the threads down,
as shown in Figure 4.
4 . The steam vent is pro-
vided with 3/4” NPT
male and 1/2” NPT
female thread for con-
necting to the steam line.
SETTING A RUNNING TIME
Using the “–” and “+” buttons, you can set the desired
running time during which the steam generator will
operate, press the “START/STOP ” button. The steam
solenoid connected to the timer is switched on. The
displayed running time is counted down while the
colon in the center of the time display flashes.
END OF RUNNING TIME
After the preset running time has elapsed, the timer
switches the connected steam solenoid off issuing short
beeps (for up to 15 seconds). The value 0:00 is shown
on the display, and the colon stops flashing.
1. Press the “START/STOP” button to stop the acoustic
signal. The previously set short time reappears on the
display (repeat function).
2. If you press the “START/STOP” button again, the
timer restarts counting down the displayed running
time.
