AquaMotionHot One AMH3K-R
Point of Use Hot Water Recirculation System
!
THANK YOU for purchasing a new Aquamotion Hot
System! For optimum reliability and performance please
follow the installation instructions outlined below.
NOTE: Please note that this is not an anti-scald unit. There
may be some warm water in the cold water line under the sink
where the circulator is installed. Once the cold water line is
opened, the warm water will disappear in a short time.
(Longer hot water lines may result in longer time for hot water
to reach the sink.)
APPLICATION
The AquaMotionHot One circulators are designed to deliver
hot water instantly at the point of use (under sink). Water
savings can be as great as 12,000 – 15,000 gallons per year
for a family of four. The AMH3K-R circulator together with the
Aquamotion “On Call™” accessories are designed to be user
friendly, reliable and to produce a professional installation.
WARNING: Risk of electric shock. The AMH3K-R kits are
supplied with a grounding conductor and grounding type
attachment plug. To reduce the risk of electric shock, be
certain that it is connected only to a properly grounding type
receptacle.
WARNING: When installing The AMH3K-R observe all
applicable electrical and plumbing codes.
WARNING: To avoid electrical shock, disconnect power prior
to connecting or disconnecting The AMH3K-R.
WARNING: Risk of electric shock. The AMH3K-R has not
been investigated for use in swimming pool or marine areas.
WARNING: The AMH3K-R is acceptable for indoor use only.

INSTRUCTIONS for AMH3K-R
1. Turn off the house water supply
2. Open both the hot and cold faucets. This will relieve any
remaining water pressure in water pipes
Aquamotion Tee Installation (see Fig. 1)
3. Locate the hot and cold shut off valves (angle stops)
typically located near the faucet(s) under the counter.
4. Remove the shut off valves that supply hot and cold
water lines to the sink from the copper pipe. For ease
of installation you may leave the compression ring and
nut from the angle stop on the hot and cold water supply
lines*.
5. Remove the ferrule ring and nut from the compression
fitting on the supplied Tee’s and install them onto the
copper supply pipes
6. Insert the ½” Copper tubing into the tee on the hot and
cold water supply pipes. Tighten nuts securely
7. Thread the angle stops (valves) to the new Tee’s. Both
of these connections are compression “fine” threads.
Never apply either Teflon tape or pipe dope on
compression threads or fittings/ This will void the
warranty of AquaMotion Tee’s.
8. Install the flex hoses by attaching one end to the
remaining port of the Tee and the other end to the
pump. MAKE SURE THE HOSE ATTACHED TO THE
HOT! VALVE IS CONNECTED TO THE INLET SIDE
(THAT IS THE OPPOSITE DIRECTION OF THE
ARROW) OF THE PUMP. MAKE SURE THE HOSE
ATTACHED TO THE COLD VALVE IS CONNECTED
TO THE DISCHARGE SIDE (THAT IS THE SIDE THE
ARROW IS POINTING TO) OF THE PUMP.
Circulator Installation (see Fig. 2)
9. Attach the flanges and gaskets to the pump casing. The
gaskets must be located between pump casing and
flange. You will need two open-end wrenches 5/8” and
11/16” inches. Firmly tighten the nuts and bolts to avoid
leaks. Do not install the pump upside down
10. Place the pump into its intended location supported by
the flanges and pump support.
NOTE: Be sure the arrows on the pump point to the cold
water side.
