Technical data 9. Disposing of the product 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 fulfill 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 fig. 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 flash. Then press and hold the connect button on the temperature sensor for more than 2 seconds. The temperature sensors internal LED will flash. 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 flash 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.

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, flashing red
(5 seconds) during installation
- The symbol flashes red for 5 seconds, when pairing between the temperature sensor and the pump has failed. Restart of the installation procedure is recommended. 4.

You must remove the lid in order to pair the devices. The LEDs modes are as follows:
FCC sections Section 15.19 (a) 3 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 modifications to this equipment not expressly approved by the party responsible for compliance could void the users 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 off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the be think innovate 99475027 0119 ECM: 1251567 Page 1 Page 2 Page 3 Page 4 Page 5 Page 6 99475027_0119_Temperature Sensor_HWR-D_IO_InDesign.indd 1-7 1/23/2019 3:38:57 PM equipment and receiver.
- Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help. This equipment should be installed and operated keeping the radiator at least 8 in (20 cm) or more away from persons body. Canadian ISED information This equipment complies with FCC/IC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Expo-
sure Guidelines and RSS-102 of the IC radio frequency (RF) Exposure rules.
