1.The pump does
not run when push
button is pressed.
A. No power at electrical outlet.
B. You’ve plugged the controller into an
electrical outlet controlled by a wall
switch, (such as the outlet under
many kitchen sinks that controls the
garbage disposal).
C.. Power cord is not secured to pump
and valve.
D. Wire to push button is not
connected well.
E. The temperature setting is already
sensing “hot” water so the pump is
not being activated.
• Plug the controller into a “hot” outlet
• Shut off power, then make sure wires
have good contact

2. The water is not
hot enough A. Pump or valve was install with water flow going in the wrong direction.
B. There is something in the piping that
has blocked the flow of water.
• Check the arrows on the housings of the
valve and pump to make sure they point in
the correct direction (see page 2).
• Check the piping for obstruction.
3. There is hot
water at the cold
water tap
A. The temperature sensitivity setting
now in place is too high, so the
pump is not shutting down soon
enough.

Installation shall be in accordance with the manufacturer's
instructions or warranty may be voided.
IMPORTANT
Operation of the D’MAND®System without being plumbed into water
lines may damage the pump and void the warranty.
Pre-Installat on Checkl st
1. ACT D’MAND®System includes:
• Pre-assembled S-50T or STS-70T pump with built-in D’ AND®Electronics
Circuit Board, PDV Valve System and Thermister
• (2) Connecting T’s - (PF-Series & PFR-Series only)
• (2) Stainless steel flex lines (PF-Series & PFR-Series only)
• (1) Push Button
• Remote receiver, wireless transmitter, battery, wire nuts and screws (PFR-Series only)
2. Tools you need:
• Pipe or crescent wrench
• Pliers
• Phillips and flat head screwdrivers
• Wire strippers
• Drill and 5/8 inch drill bit
3. Best location for the D’MAND®system:
• Typically, this would be at the fixture farthest away from the wat er heater, generally the
kitchen or master bathroom. If your hot water supply runs in two different directions
from the water heater, you may need mor than one ACT D’ AND®System.
The two custom “T”’s are designed to simplify your
installation to 1/2 inch copper hot and cold supply lines. (If
you have plumbing other than copper please call our office at
800-638-5863. Additional fittings may be required).
Installat on for the S-Ser es Systems
(PF and PFR) Models S-50T and STS-70T
1. Turn off the house water supply.
2. Open the hot and cold faucets at the fixture chosen for installation, this will relieve the
water pressure from the hot and cold water pipes.
3. Remove the shut-off valves that supply hot and cold water to the sink from the 1/2”
copper pipe. For ease of installation, leave the compression ring and nut from the
angle stop on the hot and cold water supplies.
4. Remove the compression ring and nut from the threaded side of the custom “T” and
slide them onto the other side. Attach the existing nut and ring to the end of the
threaded T and firmly tighten.
Installat on for the S-Ser es Systems (Cont nued)
5. Install the remaining compression ring and nut to the shut-off valve, slide onto the 1/2”
side of the PF-T and firmly tighten.
6. Now you are ready to attach flex lines from the 1/2” male thread of the PF-T’s to your
ACT D’MAND®System. (Teflon tape is recommended for the 1/2” threaded fittings.)
Tighten snug — Do not over tighten.
7. Refer to Page 3 – “Installing the Demand Button(s)” and “Wireless Remote Option”.
*Additional fittings may be required if your supply lines are galvanized or plastic pipe.
Install ng the ACT D’MAND System on Rec rc L ne
1. Install The Pump
A. Turn off the house water supply.
B. Install the pump in the hot water return line before it enters the water heater.
C.Install the pump so the raised arrows on the pump housing indicate the
direction of flow toward the inlet of the water heater. ake sure the electronic
control box is on top of the circulator pump. The control box attached to the
pump housing may be rotated on the body by removing the four screws that
connect them together - rotate housing until box is on top - then re-secure the
screws. (If pump is already installed on loop, turn off water supply and purge
line prior to rotating housing)
Pump Pos t on
Install the pump in the horizontal position with the D’ AND®label facing up toward the
sink (as shown in picture #4). Be sure the arrow on the pump base points left to right
(hot water to cold water side) prior to connecting the flex-lines. NOTE: Use of other
than the supplied D’ AND®parts, including the flex-lines, may restrict and delay the
flow of water from the water heater.
COMPLETING YOUR INSTALLATION
1. After installation adjustments
CHECK THE SYSTEM CAREFU Y TO MAKE SURE THE INSTA ATION IS FREE OF WATER
EAKS.All electronic sensitivity adjustments are pre-set at the factory. If adjustments are necessary
please call 1-800-638-5863 for technical support prior to making any adjustments.The sensor is
designed to signal the controller to shut off automatically when hot waterhas reached your fixture, and
not to reactivate if hot water is at the fixture. Review the troubleshooting page for additional information.
2. Try the ACT D’MAND® System and check water temperature
Once installed, turn water supply on and plug in the system. (Pump will automatically turn itself on
when it is initially plugged in without pushing the D’ AND®button). the D’ AND®System will
continue to operate until the sensor signals that hot water has arrived, then it will automatically shut
off. To test the system again, wait until pipes cool down, approximately 20-30 minutes. To operate
the D’ AND®System from another location in the home, place remote transmitter in desired
location. Push remote transmitter and wait for system to cycle. You may now turn on hot water.
3. Installing the D’MAND®System Starter Button
The manual starter button is a unique feature to the D’ AND®
System. The “on-demand” start to the circulating pump maximizes
energy savings and controls operation only when there is a
demand for hot water as compared to automatic timer controlled
systems.
A. Drill a 5/8” hole into the desired location, typically the side or
front of a vanity cabinet.
B. Insert the gray control cable from the controller through the back
side of the hole and connect black and red wires to the starter button.
C. Firmly insert the button into the drilled hole.
Note: To operate the D’ AND®System from other locations
throughout the house, additional starters can be installed and spliced
into the gray control cable provided. Or for wireless remote operation,
the transmitter/receiver kit can be easily installed. See “WIRELESS
RE OTE KIT OPTION”below for instructions.
D. If wireless remote kit is not installed, use electrical tape or wirenuts to
isolate the three leads (black, red and green) in the black control
cable.
WIRELESS REMOTE OPTION – RT-954
Wiring the Receiver
The remote receiver is the white rectangular box with the three protruding wires: black, red and green. The
receiver does not need batteries.Wire the receiver directly to the corresponding wires on the controller
by twisting each same colored wire together with gray wirenuts provided. If transmitter will activate system
from short distance, but not from further away, receiver may need to be relocated for better reception.
Installing Batteries to the Transmitter
Open transmitter with a small flat head screwdriver by inserting screwdriver into slot to release catch. Load
battery with negative side of battery toward spring. Carefully replace cover. The signal frequency can be
changed. This should only be necessary when two D’MAND®Systems are in the same home or
your neighbor has the system. Call 800-638-5863 for assistance.
4. Connect D’MAND®
System, install push
button and plug in.
