Size the pump to provide a
maximum of 2 GPM (7.5 L/min)
through the system at 10 ft (3 m)
of head plus piping losses.
Adjust the flow using a globe
valve and verify the flow rate
with the maintenance monitors.
(Refer to the Techinical Sheet.)
Pump Control Signal
Pump Control Signal is the
preferred method to control the
recirculation pump.
For pumps greater than 100 W,
a relay connection must be
used. If the Pump Control Signal
is not used, an Aquastat may be
used to control the pump.
Aquastat
Set the Aquastat to 10˚F
(-12˚C) below the set
output temperature.
An aquastat is the
minimum pump control
requirement
in order to maintain the
full recirculation
warranty.
* Service Valve Kit with Pressure Relief Valve
It is recommended the use of Service Valve Kit with Pressure
Relief Valve with the installation. The kit includes an integrated
shut-off and service valve with unions and a pressure relief valve.

Recirculation System
• With a Recirculation System, the water from the Water Heater to the fixtures can be warmed up in advance.
You can get hot water to your fixtures more quickly with less waste of water.
• See the Owner’s Guide for more information about how to set up for recirculation opelation.
• Scale build-up is more likely to occur in a Recirculation System, therefore it is critically important to have
proper water treatment and maintenance.
