INSTALLER
PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.
How the Autocirc Pump System Works The Autocirc pump is installed under the
sink farthest from the water heater, where hot water takes longest to arrive.
Pump Operation
Pump Not Operation
Model with fixed thermostat E1-BCANCT1W-06
- A built-in temperature sensor automatically turns the pump ON when the water temperature in the hot water supply line cools down to 85°F (29°C) . The pump then moves the cool water in the hot water supply line into the cold water supply line.
- Autocirc Pump turns OFF automatically when water temperature reaches 95°F (35″C), ensuring instant availability of shower warm water with maximum temperature hot water only seconds behind.
- When the pump is OFF, a built-in auto closure device (non-return valve) prevents hot and cold water mixing.
- Hot water will also be instantly available at all other faucets/taps between the water heater and the sink under which the Autocirc pump is installed .
Model with adjustable thermostat E-1-BCANRT1 W-06
- For models with the adjustable thermostat, there is an adjustable “ON” temperature range from 7TF to 91 °F (25°( to 33°C). This built-in temperature sensor will turn the circulator OFF when it reaches 95°F (35°C) and turn the circulator on when the temperature cools down to the “ON” temperature set point.

Pump System – Typical Schematic Diagram
No Recirculation Line Required
Note: At the sink under which the Autocirc pump is installed some “luke
warm” water will appear in the cold water line due to the transfer of water
from the hot side to cold side. This luke warm water will, however, disappear
in a short time(4-5 seconds) once the cold fauceVtaps is opened.

Australia
This pump must be installed in accordance with AS3500
U.L. Caution
This pump has been tested using water only. Its suitability for use with
liquids other than water is the end user’s responsibility .
CAUTION: PROPERTY DAMAGE HAZARD
It is not advisable to install circulators in an attic or upper floor over
finished living space. If the circulator must be installed over head, or over
expensive equipment, provide adequate drainage in the event of leakage.
Failure to follow these instructions could result in property damage.
Installation
Step 1
If not already available, install a 115 Volt/ 60Hz outlet within six (6) feet
of the installation site (the faucet/tap farthest from the water heater), as
the Autocirc is supplied with a 6 ft. long, grounded cord. The Autocirc pump
requires only 14 watts and 0.3 amps of power (see Fig. 1).
Step 2
Fasten the Autocirc to the wall under the sink using the wall bracket provided
in the Autocirc kit. Be sure the pump timer is turned toward the front and is
accessible for setting and changing the time (see Fig. 2). The pump must be
installed only in a vertical position as shown
CAUTION: Do Not fasten pump to a thin wood panel wall as this might create a vibration noise when the pump is operating.
Step 3
Close the under sink hot and cold water riser shut-off valves and open the hot
and cold water faucets/taps to relieve the water pressure. Close the water
faucets/taps.
Note: in some older homes, the riser shut-off valves may be difficult to shut off completely. If this is the case turn the water off at the main water inlet valve to the house.
Remove the existing flexible line connection to the hot and cold water
faucet/tap threaded nipples
(see Fig. 3).
Note: If felt necessary, replace these existing flexible hoses with new stainless steel braided flexible hoses in the lengths required.
Step 4
Screw on the two existing 1/2” hose connections tothe corresponding hot and
cold sides of the pump housing ( see Fig. 4 ). Be sure not to “kink” these
existing hose lines during bending which may prevent adequate flow and/or
cause the valves to break.
Note: It is recommended that the rubber washers in the hose connections be inspected to ensurethey are in reusable condition. If not, they should be replaced.
Step 5
Screw on the 3/8” end of the purchased flexible hoses to the 3/8” connections
on the pump housing. Screw on the 1/2” end of these same two hoses to the
underside of the hot and cold water faucets/taps making sure to match the hot
and cold sides marked on the pump housing with the corresponding faucet/ tap.
Be sure the hot side connection hose is attached to the hot water faucet/tap
and the cold water side connection is attached to the cold water faucet/tap.
Be sure the hoses used are long enough to allow the pump to be positioned as
originally planned. **( see Fig. 5)
**
Step 6
Be sure the screw ring attaching the motor to the pump housing is securely
hand tightened. Do not over tighten the screw ring. Open the faucet/tap hot
and cold riser shut off valves to insure there are no water leaks at any
connections.
CAUTION: Fasten screw ring until tight to prevent leakage.
Step 7
Plug the pump cord into the wall outlet and start up the pump system (see next
page).
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.
Autocirc Start Up Procedures
Timer Controlled OperationIf 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 Figure 6 (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.
E1-BCANRT1 W-06: This model comes with an adjustable “ON” temperature feature, and may be set to activate between 7rF (25’C) and 91 ‘F (33’C). The pump automatically turns off at 95’F (35’C) and turns on at the “ON” temperature set point. A thermostat dial is located just above the timer housing on the body of the pump.
NOTE: The E1-BCANRT1 W-06 start thermostat is pre adjusted to 91 ‘F (33’C) at the factory, and will provide the best pump performance at this setting.
Maintenance and Trouble Shooting
The pump does not turn on
- Ensure the timer slide switch is set to the “ON” position or the “~” position, that the timer clock is programmed to allow operation; and that there is power to the outlet.
- If the pump is installed under a kitchen sink, make sure the outlet is not controlled by a wall switch (i.e., garbage disposal).
The pump is noisy when on
- Turn off the Autocirc pump. Turn on the hot and cold faucets/taps to be sure all air is purged from the system.
- If the noise continues, unplug the pump and turn off the faucet/taps shut-off valves. Remove the pump from the wall bracket, loosen the screw ring to separate motor from the pump housing and check for any foreign matter in the rotor cavity. Also ensure the rotor is properly set on the motor bearing by pushing down on the rotor.
- If a noise occurs when the pump turns off it is likely to be “water hammer” that results from the closure of the built-in valve. In this situation, water hammer arresters may be installed on the hot and cold lines.
Hot water is not instantly available at all my faucets/taps
- Instant hot water will be available at all the hot water faucets/taps on the main plumbing line between the water heater and the faucet/taps under which the Autocirc system is installed. Hot water faucets/taps that are “branched” off this main hot water supply line will take longer for the hot water to arrive, however, usually faster than before installing the Autocirc .
I am away from my home for extended periods of time (2 weeks or more)
- You may chose to turn the system off (slide the timer switch to the “OFF” position) as there is no need to maintain hot water in the supply line when no one is home to enjoy this convenience. When returning home, prior to turning on the system, we recommend that you turn on the hot and cold faucets/taps at the sink where the Autocirc system is installed until all air is purged from the dormant system and the water flows smoothly from the faucets/taps. Then slide the timer switch back to either the “ON” or ” ” position.
