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.
WARNING: Circulator must be installed on and
supported by the circulation piping.
