24-HOUR AND 7-DAY TIME SWITCHES
MECHANICAL BLOWNDOWN TIMER
(PN 103805)
The Time Clock controls boiler operation. The boiler is ON when the timer
is ON. The Blowdown Valve will open when the Timer turns OFF.
PROGRAMMING
For CU steam bath generators equipped with Automatic
Blowdown Systems CU81500 and CU81600, refer to the
following instructions for time clock operation and settings.
Timer settings for blowdown operation are at the discretion of
the owner/operator.
The weekly program dial shows the seven days of the week and
AM/PM imprints for each day.
The time switch is set by pushing the captive trippers to the outer ring position for the
entire period that the boiler is to be turned ON, i.e., 2 hours to each tripper on the 7-day
dial. When the tripper is pushed to the inside, the boiler is in the OFF position, and initiat-
ing the blowdown cycle. Due to the timer having one tripper for every 2 hours, the boiler
will need to be OFF a minimum 2 hours. If less down time is needed the digital timer (PN
103662) can be set to the minute.
SETTING TIME
To set the current time and day of week, turn the minute hand
clockwise. Do not set the time by rotating “Outer” Dial.
Turn the minute hand clockwise until the day of the week and the time of day
on the outer dial is aligned with the triangle marker on the inner dial (two o'clock).
Example for 7-day program dial Monday 10:30 AM. Turn the minute hand clockwise until
Monday 10:30 AM is aligned with the triangle on the inner dial. The hour
and minute hand will show exactly 10:30.

at the discretion of the owner/operator
as follows.
