1. Location
The system is intended for indoor use
only in areas safe from droplets and
splashes. Maximum ambient tempera-
ture is 104 °F (40 °C).
To fulll the “California water heater
regulations 2017 - Title 24”, install
a temperature sensor HWR-D in
proximity to the pump. If the system is
to be operated without the temperature
sensor, skip this installation step.
2. Tools
You will need the following to install the
temperature sensor HWR-D:
- Phillips PH1 screwdriver.
3. Installing the product
Note: Use thermal compound (heat-
conducting grease) between the tem-
perature sensor and the pipe system.
Thermal compound is not included.
Use only one temperature sensor per
system. Follow these steps to install
the temperature sensor: 1. Remove the
lid of the temperature sensor case. 2.
Remove the pull-tab from the end of
the AA lithium battery in the sensor
case. The temperature sensor will start
up. 3. Mount the temperature sensor
on a straight section of pipe. Apply
thermal compound (heat conducting
grease, not included) to the back of the
sensor case as shown in g. 3. Position
the temperature sensor to have the
best possible contact with the pipe sur-
face. Loosely position the pipe clamp
strip around the end of the temperature
sensor. 4. Tighten the pipe clamp strip.
Keep the clamp on the opposite side of
the pipe from the temperature sensor.
a. To pair the pump and the tempera-
ture sensor: Press and hold the con-
nect button on the pump for 2 seconds.
The blue connect symbol on the pump
will ash. Then press and hold the
connect button on the temperature
sensor for more than 2 seconds. The
temperature sensor’s internal LED will
ash. After successful pairing of the
pump and the temperature sensor, the
blue connect symbol will be on continu-
ously for 5 seconds on both devices.
If the pairing fails, the connect
symbol will ash red for 5 seconds
on the pump. If pairing fails, retry the
pairing procedure. 5. Replace the lid
of the temperature sensor case. 6.
Tighten the two end screws on the
temperature sensor case. For best
performance, fully tighten the screws
but do not overtighten.

4. Control functions
The internal LED is located on the
temperature sensor beneath the lid.
You must remove the lid in order to
pair the devices. The LED’s modes
are as follows:
Internal LED, ashing blue - The
symbol ashes blue when the tem-
perature sensor is ready for pairing
with the pump.
Internal LED, blue - The symbol
lights blue for 5 seconds when pair-
ing between the temperature sensor
and the pump has succeeded.
Internal LED, ashing red
(5 seconds) during installation
- The symbol ashes red for 5
seconds, when pairing between the
temperature sensor and the pump
has failed. Restart of the installation
procedure is recommended.

This device complies with Part 15 of
the FCC Rules. Operation is subject
to the following two conditions: (1)
this device may not cause harmful
interference, and (2) this device must
accept any interference received,
including interference that may
cause undesired operation.
Section 15.21
Any changes or modications to this
equipment not expressly approved by
the party responsible for compliance
could void the user’s authority to oper-
ate this equipment.
Section 15.105 (b)
This equipment has been tested and
found to comply with the limits for a
class B digital device, pursuant to Part
15 of the FCC Rules.
These limits are designed to provide
reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses and
can radiate radio frequency energy
and, if not installed and used in ac-
cordance with the instructions, may
cause harmful interference to radio
communications. However, there is
no guarantee that interference will
not occur in a particular installation.
If this equipment does cause harmful
interference to radio or television
reception, which can be determined
by turning the equipment o󰀨 and on,
the user is encouraged to try to correct
the interference by one or more of the
following measures:
