Goulds Laing Thermotech AutoCirc ACT E1 Hot Water Recirculation Pumps
AutoCirc ACT-E1 instant hot water circulation pump system from Goulds Laing Thermotech. Pump is installed under the sink or faucet farthest from the water heater -- where hot water usually takes the longest amount of time to arrive. A built-in temperature sensor automatically turns the pump on when the water temperature in the hot water supply line cools down to 85 deg. F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater.
The pump turns off automatically when the hot water supply line to the faucet reaches 95 deg. F, ensuring the instant availability of shower warm water with maximum temperature hot water only seconds behind. AB1953 compliant.
NOT FOR USE WITH TANKLESS WATER HEATERS

| #1 | Q: I have purchased and installed model E1-BCANRT1W-06 w/adjustable on feature. Would like to know if the thermostat will work in conjunction with the timer, or must I choose one or the other as the manual seems to indicate by moving the switch to the on position? Also, would like to have a source for E1 rotor replacement kit. Thanks- TJ A: The thermostat and timer work together. The timer must be active for the pump to cycle on/off based on the thermostat temperature reading. When the timer is not active, the pump will not operate at all. We can special order you the rotor replacement kit if required. Asked on 2021-01-14 by Tim |

| #2 | Q: Is this sweat connection or threaded i need threaded pls recommend right product. I have no dedicated return line and a regular hot water heater. I installed power under the master sink. Also do you sell the supply lines too.? A: This is threaded. Its meant to connect to the typical flexible hoses use under sinks. We do not sell the hoses. Asked on 2020-01-16 by Candy |
| #3 | Q: is there any maintenance that needs to be preformed? A: Not really but there is a short maintenance section on page 6 of the manual: https://www.hvacquick.com/catalog_files/Laing_E1_IOM.pdf Asked on 2020-01-16 by Wayne |
| #4 | Q: Can a replacement impeller be purchased and if so, where can I order? A: We do not sell the parts for these. Sorry. Asked on 2019-07-09 by JB |
| #5 | Q: I would like to purchase an E1-BCANRT1W-06, but without the timer. I plan to control the on time via my smart home hub. What is the model number I should order with threaded connections? A: There is no model that has the 4 connection ports and no timer. You can set the timer to run 24/7 on the E1-BCANRT1W-06 and control it via your other system. Asked on 2019-04-24 by Joe |
| #6 | Q: How many amps does the unit pull? My dishwasher & disposal are on the same 20amp circuit that I want use. Will this be a problem? A: Its 14 watts so roughly 0.12 amps. Doubt it would be a problem. Asked on 2018-12-08 by Richar |
| #7 | Q: Is a separate line needed to take the water back to the hot water heater or does this just pump directly into the cold water supply? A: It uses the cold water line as the return line back to the water heater. Asked on 2018-02-25 by Chet |
| #8 | Q: Is there a warranty on this product? A: Yes, please see page 6 of the installation manual for the full text: http://www.hvacquick.com/catalog_files/Laing_E1_IOM.pdf Asked on 2017-01-10 by Delmer |
| #9 | Q: I added an additional hot water circulation line from my farthest faucet back to my water heater. The pump is now mounted at the water heater. Is it possible for me to raise the temperature setting in the pump so I can have higher than 95 degrees? A: That is a fixed thermostat set to Health and Safety standards,,They dont want scalding water available at the turn of a tap. The model that does allow for temperature adjustment is solely for the starting point, it still turns off at 95. Asked on 2014-12-30 by Seattle Washington |
| #10 | Q: We currently have 105 degree water at the faucet once cold water is cleared out. Since pump turns off at 95, will we still have 105 degree water if needed, just warmer water sooner? A: The pump turns off JUST BEFORE the 105 water gets to your faucet (roughly at 95F). That means when you turn on your faucet you will get 95 water immediately followed by the full warm water.

| #11 | Q: If manually switched can the E1 pump be used with a tankless water heater? A: No. The E1s are not rated for tankless heaters. Only the E10 is high enough flow to work with tankless. Asked on 2014-10-07 by Bill |
| #12 | Q: Instead of using the timer is it okay to wire in an on / off switch? A: There is no place to wire in an on/off switch but you could cut power to the unit to control it. Asked on 2014-10-07 by Bill |
| #13 | Q: Is there any chance that when the water is returning to the water heater that it flows past the water heater and out through the water line coming into the house? A: No. The water pressure from the street far surpasses the pressure this pump can generate, and I believe the water meter acts as a check valve, and/or there should be one in the system at some point.

| #17 | Q: I just installed an ecocic, E1-BCANCT1W-06. There is a dial on the bottom and I do not understand which setting to use. There were no instructions in the box, but I hooked it up and water is circulating. The box had part No. LHB081000092 Autocirc Connectioon (NPT). The dial is set on 3 but I have no idea what it should be set to perform well. This is a 2 person home, 2000 sq ft, device is set up furtherist from 50 gallon hotwater tank. It normally takes 7 - 10 minutes to get hot water at the back location. A: That dial is a speed control, the setting you have it should be fine as this pump is designed to work behind the scenes.

| #18 | Q: There is a split in my upstairs plumbing. Can this pump be used in conjunction with an addition of something link a Grundfos comfort valve in the 2nd sink? This would allow circulation in the second bathroom which would not fit an under sink pump. Thanks A: These will not work with the comfort valve systems, those need water pushed into them and these pull the water across the house. Asked on 2014-02-12 by AJV |
