INSTRUCTION MANUAL 671075184 REVISION A Laing Thermotech Series Autocirc® Instant Hot Water Pump Model: ACT E10
Model with fixed thermostat • A built-in temperature sensor automatically turns the pump ON when the water temperature in the hot water supply line cools down to 89.6°F (32"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 warm water with hot water only seconds behind .
Preparation for Installation : Assemble the parts and tools required : 1. Open and inspect Autocirc pump package. 2. Autocirc pump package includes the pump with a built-in timer, a 6ft. cord, and wall mounting bracket. 3. Two stainless steel flexible hoses (1/2" x 3/8") - length as required . (sold separately) 4. Adjustable wrench and screwdriver. 5. Select the sink under which the Autocirc pump is to be located (the sink where hot water takes longest to arrive) . A CAUTION: PROPERTY DAMAGE HAZARD . . .
Remove the existing flexible line connection to the hot and cold water faucet/tap threaded nipples (see Fig. 3). (TIP: Mark the hot and cold water flexible lines to easily identify them). Note: If necessary, replace the 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 to the corresponding hot and cold sides of the pump housing (see Fig. 4).
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 .
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 .
