Taco SmartPlus 006 Hoja De Instrucciones

U.S. Patent # 8,594,853
SUPERSEDES: April 7, 2016
Plant ID# 001-4243
aPPlICaTION:
The Taco SmartPlus is designed to increase hot water comfort while con-
®
serving 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.
PUmP CONTrOl OPTIONS:
The SmartPlus has a "Mode Select" toggle switch that allows for 2 operation
modes. "Pulse" or "Smart" mode can be selected using the toggle switch
located on the electronic control board (see Figure 1). A yellow LED indicates
which mode is selected. All operation is automatic, no manual timer or tem-
perature setting is required.
• "Pulse" mode
When set for "Pulse" operation, the SmartPlus
will run for 1 to 10 minutes "ON" and 10 minutes
"OFF" to maintain hot water at all fixtures.
• See #5 Variable Run Time Setting on page 2.
• "Smart" mode
When set for "Smart" operation, the SmartPlus
will run in "Pulse" mode as above for the first 7
days. During the first 7 days, the SmartPlus will
monitor and record the home's hot water usage
pattern. For the next 7 days, the SmartPlus will
use the preceding week's usage pattern to
cycle the pump. This process will be repeated every 7 days. The pump
will cycle for 1 hour before and after each recorded hot water demand.
WarNINg: all local plumbing and electrical codes should be fol-
lowed when installing this product.
WarNINg: risk of electrical shock. This pump is supplied with a
grounding conductor and grounding-type attachment plug. To
reduce the risk of shock, be certain that it is connected only to a
properly grounded grounding-type receptacle
CaUTION: Do not plug in the SmartPlus power cord until the sys-
tem is filled with water and purged of air.
SUggeSTeD PlUmbINg INSTallaTION PrOCeDUre:
Hot Water Supply line (Option No. 1) - Install the SmartPlus on the
domestic hot water (DHW) supply line pumping away from the DHW
source. The external sensor provided with the SmartPlus should be
installed on the DHW supply line. Refer to Figure 2 below.

1. Install the SmartPlus in-line on the DHW supply line downstream of
the hot water source as shown in Figure 2. Be sure the directional
arrow on the casing is installed with the arrow pointing away from the
hot water source.
2. Install all other system components as shown in the piping diagram
in Figure 2.
3. When all components are installed, fill system with water.
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.
7. The SmartPlus is shipped from the factory in "Smart" mode. To switch
the pump to "Pulse" mode, remove the 2 electrical box screws and
cover. Change the position of the toggle switch on the circuit board to
"Pulse" (see Figure 1). Replace the cover and secure with 2 screws.
8. Plug the external temperature sensor provided into the "TEMP SEN-
SOR" receptacle on the side of the electrical box. Attach the sensor to
the hot water supply pipe downstream of the pump using the black zip-
tie connector provided. See Figure 2.
9. Once the system is filled and air is purged, plug in the SmartPlus
power cord.
NOTe: The temperature sensor must be installed and connected
in either "Pulse" or "Smart" mode.
NOTe: The SmartPlus must be installed and supported by the
circulation piping.
Hot Water return line (Option No. 2) - Install the SmartPlus on the
domestic hot water (DHW) return line pumping toward the DHW source.
The external sensor provided with the SmartPlus should be installed on
the DHW supply line. Refer to Figure 3 below.

Figure 3. Be sure the directional arrow on the casing is installed with
the arrow pointing toward the hot water source.
2. Install all other system components as shown in the piping diagram in
Figure 3.
3. Follow steps 3 through 7 listed under the Hot Water Supply line
(Option No. 1) section.
4. Plug the external temperature sensor provided into the "TEMP SEN-
SOR" receptacle on the side of the electrical box. Attach the sensor to
the hot water supply pipe as in Figure 3, using the black zip-tie connec-
tor provided.
5. Once the system is filled and air is purged, plug in the SmartPlus
power cord.
NOTe: The temperature sensor provided may not have enough
wire length to reach the DHW supply pipe with the SmartPlus
