Autocirc Start Up Procedures
Timer Controlled Operation
If timer controlled operation is desired, the timer may be programmed to allow
the Autocirc to operate during the hours desired (i.e. “ON” from 7:00 a.m. to
9:00 p.m. and “OFF” from 9:00 p.m. to 7:00 a.m.) as follows:
• Open timer cover and rotate the dial clockwise until the correct time is aligned
with the pointer at the top (12 o’clock position) of the dial.
• Automatic Operation: PULL the tabs Upward on timer for the desired
operating period of time. Example: If the desired operating time is 7:00 a.m. to
9:00 a.m., all tabs should be Pulled out between 7 and 9. NOTE: The timer may
be set for multiple operating periods of time.
• Slide the switch bar to “ ”.
The timer mode will provide the most cost effective method of operation and
can be programmed to run only during the time periods when hot water is
most frequently required. Even during controlled timer operation, the Autocirc
will only turn on when the built-in thermostat senses that additional hot water
is required at the point of installation.
Thermostat Operation Mode
To operate the Autocirc “thermostatically” without the timer, slide the switch to
the “ON” position. In the “ON” position the pump runs “automatically”,
whenever the built-in thermostat senses the requirement for hot water. In the
“OFF” position the pump does not operate at any time.
In either the “ON” or “OFF” position, the timer dial continues to rotate through
the 24 hour sequence keeping accurate time. When timer controlled operation
is resumed, the Autocirc will operate during the previously programmed time
sequence(s).
Note: The Autocirc will most likely start running immediately and turn off after
a few minutes once hot water reaches the faucet. It will then continue cycling
“ON” and “OFF” as required during the programmed sequence of operation.
Do not be concerned if the pump does not begin running immediately after the
pump is plugged in. This just means that there is already hot water at the hot
water faucet and the pump will turn on “automatically” when the hot water
line cools down.

Note: The above installation method applies to most
situations where faucets/taps are connected to the
hot and cold water supply lines with braided flexible
hose/shut off valve arrangements. If the under sink
arrangement is different (i.e. the risers are hard
copper or plastic), then other parts may be required
for the installation.
