WH40 ELECTRIC WATER HEATER TIME SWITCH
DOUBLE POLE, 10,000 WATTS (40 AMP) MAX., 250 VOLT - 60 HZ.
This Time Switch will repeat a preset schedule
daily, except when the EXTERNAL MANUAL
LEVER is used. This manual lever permits the
user to turn the water heater ON and OFF ahead
of the schedule. The Time Switch will resume the
preset program by the next scheduled
ON or
OFF operation.
NOTE: The manual lever is inoperative for 15
minutes immediately after the automatic
operation.
The diagram on the right shows the mechanism
and wiring of this Time Switch. The
TIME
POINTER is used to line up the correct time-of-
day on the CLOCK-DIAL . The ON and OFF
TRIPPERS turn water heater ON and OFF at the
times indicated by their respective position on
the
CLOCK-DIAL .
TO SET PROGRAM
First, mount silver finished (ON) trippers at times
you wish water heater to start operating. Place black (OFF) trippers at times you want to
turn water heater
OFF . Fasten trippers to dial by pushing them against the edge of the
clock dial, then turning screws TIGHT with fingers.
Second, PULL clock dial out (toward you) and turn in either direction until correct time-
of-day (the time now, when switch is being put into operation) is directly under the time
pointer.
Do not move pointer.
Third, close Time Switch cover. Make sure it is latched and locked, if needed.
AFTER POWER FAILURE
(or if water heater was disconnected at the main panel), you
must reset clock dial to the proper time-of-day.
TO SUSPEND AUTOMATIC OPERATION - Remove trippers from dial. Set manual
lever as desired.
CAUTION: Always disconnect power at main panel before servicing this Switch or
the water heater.
