The Taco HLS-2 Hot-Link
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 gallons 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-Link System includes a high performance
Stainless Steel 00 circulator with a pre-wired power cord
and programmable 24 hour timer. This circulator is suitable
for most residential homes with hot supply lines up to 150
feet in length.
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.
WARNING: To avoid electrical shock, disconnect the
power supply to the circulator and the main
electrical unit.
WARNING: Circulator must be installed on and supported
by the circulation piping.
