Taco SmartPlus-e Instruction Sheet

U.S. Patent # 8,594,853
SUPERSEDES: NEW
Plant ID# 001-5008
APPLICATION:
The Taco SmartPlus-e™ consists of a 006e3™ ECM high-efficiency circu-
lator combined with our SmartPlug Instant Hot Water Control
SmartPlus-e is designed to increase hot water comfort while conserving
water and energy. By recirculating "cooled" hot water back to the water
heater, the wait for hot water is reduced to seconds. A dedicated hot water
recirculation line within the piping system is required.
HIGH QUALITY FEATURES:
The SmartPlus-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 300 feet.
SmartPlug Instant Hot Water Control learns weekly hot water usage
patterns in the home. It uses that information to run the 006e3 providing
hot water when its needed.
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.
CAUTION: Do not plug in the 006e3 circulator power cord until
the system is filled with water and purged of air.
WARNING: The 006e3 circulator must be installed and
supported by the circulation piping.
Installing the SmartPlus-e 006e3 Circulator:
Hot Water Return Line (Option No. 1)
1. Install the SmartPlus-e 006e3 circulator in-line on the DHW return line
pumping toward the hot water source as shown in Figure 1. Be sure the
directional arrow on the casing is installed with the arrow pointing toward
the hot water source.

4. Close the isolation valve on the return line between the water heater
and the flow check valve.
5. Open the drain valve between the
isolation valve and flow check
valve and drain water until all air
is purged from the line.
6. Close drain valve and open
isolation valve.
To change operating speed settings:
Modify the performance of the 006e3 as needed by rotating the
programming dial using a flat screwdriver. A blue LED will illuminate
when the circulator is powered on. The LED will flash each time mode
is changed. The selection of the right performance curve depends on
the characteristics of the system and the actual flow and head
requirements. See 006e3 Performance Curves and Setting Selection
Guide on page 3 to determine best speed setting for the system.
NOTE: If flow velocity noise develops, turn dial counter-clockwise to
reduce pump speed until noise disappears.
