Application:
The Taco Hot-LinkPlus-e
recirculation ensures instant hot water comfort at showers and
faucets. It saves thousands of gallons of water per year by
supplying fresh hot water to the fixtures while returning the
“cooled” hot water back to the water heater through the cold water
line. The average family can achieve yearly savings of up to
12,000 gallons of water normally wasted down the drain while
waiting for hot water.

High Quality Features:
The Hot-LinkPlus-e System includes a high-efficiency Taco
multi-speed 006e3 ECM permanent magnet circulator. The
circulator is suitable for most residential homes with hot water
supply lines up to 100 feet.
SmartPlug Instant Hot Water Control® learns weekly hot water
usage patterns in the home. It uses that information to run the
circulator providing hot water when its needed.
The unique Hot-Link® Valve is the key to the system. Made of
durable high temperature polymer, it creates an easy-to-install
return loop through the cold line from the furthest fixture back to
the water heater. An integral thermal sensor disc closes when hot
water reaches the valve. An internal flow check prevents cold
water from backing into the hot water line. Stainless steel braided
flex hoses complete the installation.
Installing the Hot-LinkPlus-e 006e3 System Circulator:
WARNING: All local plumbing and electrical codes should be
followed when installing this product.
CAUTION: To ensure all plumbing system components are
protected from the damaging effects of water hammer, be sure
an approved water hammer arrestor is installed in the system
per locally recognized National plumbing codes.

Install the Hot-LinkPlus-e 006e3 circulator by connecting to
the union nut/tailpiece attached to the water heater outlet.
Circulator motor must be in the horizontal position. To set the
circulator speed turn the dial to the 006 performance point.
NOTE: If flow velocity noise develops at the 006 setting turn dial
counter-clockwise to reduce pump speed until noise disappears.
CAUTION: Do not run circulator dry. Permanent damage
may result and will void warranty.
9. Reconnect the hot water supply line to the union tailpiece attached to the circulator discharge.
10. Open the supply valve to water heater. Let water run until all
air is purged from lines. Check for any leaks. If leaks are
detected, close supply valve and tighten all connections.
11. Shut off open hot water faucet.
WARNING: Circulator must be installed on and
supported by the circulation piping.

Installing the Hot-LinkPlus-e Hot-Link Valve:
1.
Select the hot water faucet furthest from the water heater. If
your plumbing system branches in two
another Hot-Link Valve may need to be installed at the end of
each run (see Figure 1 on page 1).
CAUTION: Do not use pipe dope or Teflon tape on the
valve body threads.
CAUTION: Use caution when attaching flex hoses to the Hot-Link
Valve to prevent cross-threading or stripping of the threads.
2. Shut off the hot and cold angle stop valves below the sink.
3. Open the hot and cold faucets to purge water from the lines.
4. Disconnect the hot and cold flex hoses from the 1/2" faucet
connections beneath the sink and reconnect them to the
respective hot and cold inlet ports on the Hot-Link Valve.
Locate the flow arrows on the side of the valve to verify flow
direction.
5. Install the 1/2" x 1/2" flex hoses provided. Connect one hose to
the hot outlet of the valve and the hot water connection on the
faucet (left side). Connect the second flex hose to the cold
outlet of the valve and the cold water connection on the faucet
(right side). See Figure 5 below.
6. When all connections are made, open angle stop valves and
check for leaks.
7. Attach the Hot-Link Valve to the wall using anchor
screws provided.
NOTE: The Hot-Link Valve can be disassembled for service and
cleaning. Repeat steps number 2 and 3. Unthread the valve stem
from the body and clean internal screen of debris (see Figures 3 &
4 above). Reattach valve stem securely to prevent leaks. Open
angle stop valves and check for leaks.

Installing the Hot-LinkPlus-e SmartPlug Instant
Hot Water Control®:
Application:
Taco's Hot-LinkPlus-e SmartPlug Instant Hot Water Control is
designed to upgrade any hot water recirculation system.
SmartPlug replaces inefficient timers and aquastats typically used
in recirculation systems. It adds intelligence to your system by
learning when hot water is used in the home. The pipe-mounted
sensor records daily hot water usage patterns during the course
of the week. Recorded data is used to automatically run the
006e3 at the same times the following week. So hot water is
awlays available when it is needed. If usage pattern changes, the
SmartPlug adjusts automatically.
Benefits:
Easy to Install: Upgrades the Hot-LinkPlus-e 006e3 circulator to
“Smart” operation.
Comfort and Convenience: Hot water is available in seconds. No
timers or programming required.
Efficiency: “Smart” mode maximizes hot water comfort and energy
savings.
Reliability: The SmartPlug, when combined with the 006e3
circulator, provides whisper quiet operation and industry leading
electronics for proven performance and dependability.
SmartPlug Control Options/Features:
“Smart” Mode: When set to Smart mode, the SmartPlug will run
in Pulse mode as described below for the first 7 days of
operation. During the first 7 days, the SmartPlug monitors and
records the home's hot water usage pattern. For the following
7 days, the SmartPlug will use the preceding week's usage
pattern to cycle the 006e3 during the recorded hot water
usage times. This process of recording and repeating is
continuous, and automatically adjusts the 006e3 ON times to
match the household's usage pattern.
“Pulse” Mode: When set to Pulse mode, the SmartPlug will cycle
the 006e3 ON for 5 minutes, then OFF for 10 minutes to
maintain hot water at all faucets and taps. It will repeat the
cycle continuously.
Vacation Mode: After 36 hours of no hot water usage, the
SmartPlug will automatically turn the 006e3 OFF, and will
automatically restart when hot water usage is detected.
Exercise Function: While in vacation mode, the SmartPlug will
cycle the 006e3 ON for 10 seconds every 7 days to
prevent corrosion or scale buildup.
