Installation, Operating & Maintenance Manual
Functionality of the Timeswitch
The countdown timer uses a relay to switch the steam sole-
noid 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.
BEFORE USE
Before installing and using this timer, it is absolutely neces-
sary 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.
1.
SHOCK HAZARD!
Install the timer per these instruc-
tions before connecting to the main supply. Never touch
live contacts or components.
2. Protection from contact with the line voltage compo-
nents must be achieved by proper installation in a 4 x 4
junction box. When installing the timer, ensure the fasten-
ing sliders prevent the timer from being removed.
3. DO NOT install the timer in a wet or damp location.
4. DO NOT install the timer inside the steam room.
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 provided with 3/4” NPT male and
1/2” NPT female thread for connecting to the steam
line.
