SUPERSEDES: NEW
Plant ID# 001-5006
Application:
The Taco Hot-LinkPlus System for Domestic Hot Water
recirculation ensures instant hot water comfort at showers
and faucets. By supplying fresh hot water to the fixtures
while returning the "cooled" hot water back to the water
heater through the cold line, it also saves thousands of gal-
lons of wasted water per year. The average family can
achieve yearly savings of up to 12,000 gallons of water nor-
mally wasted down the drain while waiting for hot water.

High Quality Features:
The Hot-LinkPlus System includes a Taco SmartPlus cir-
culator designed specifically for use with the Taco Hot-Link
Valve. The circulator and valve are suitable for most resi-
dential homes with hot water supply lines up to 100 feet.
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 fix-
ture 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
line. Stainless steel braided flex hoses complete the instal-
lation.
Installing the Hot-LinkPlus System Circulator:
WARNING: To avoid electrical shock, disconnect the power
supply to the circulator and the main electrical unit.
WARNING: 1. Circulator must be installed on and supported by
the circulation piping.
2. The addition of unions on both the suction and
discharge side of the circulator is recommended.
