Product
Features
- HEATIT HIP smart hot water recirculating pump adopts a plastic-sealed permanent magnet synchronous motor with ultra-low safe voltage (24V).
- Easy to install with the necessary accessories included. 10′ power cord. Built-in thermostat. Maintenance-free. Can be used with all types of pipe.
- Three modes can be chosen: energy-saving constant temperature mode, smart constant temperature mode, and manual mode. When the water temperature in the pump is lower than 33 ℃, the pump will push the cold water back to the water heater. As the temperature hits 38 ℃, the pump will stop working.
- Advanced motor technology: Permanent magnet brushless motor DC motor makes the pump more powerful, more
quiet and more durable. (Max flow 6 GPM, Max head 39.3ft)

IMPORTANT SAFEGUARDS AND WARNINGS
Thank you very much for choosing our products. Please read the Instruction Manual carefully and keep it properly before installation and use.
Important safeguards and warnings
- Please read the Instruction Manual and keep it properly before installing and using the product.
- The electric pump must be reliably grounded before use, and leakage protection devices should be installed.
- It is forbidden to touch the electric pump during operation.
- Dry running of the electric pump is strictly prohibited.
- It is strictly prohibited for children, and persons with no capability or limited capability to use the product without the supervision of guardians (such as not being taught the safe use method of the product and understanding the risks involved).
- The pump system must be able to withstand the maximum pump pressure.
- The manufacturer shall not be held responsible for any consequences caused by the user modifying the electric pump without authorization or operating the electric pump beyond the operating conditions.
GENERAL INSTALLATION INSTRUCTIONS
**** The product is installed under the faucet furthest from the water heater in each loop.
Conveying liquid
The conveying liquid is softened water and thin, clean, non-corrosive, non-
explosive liquid without solid particles, fibers, and mineral oil, and the PH
value of the medium is between 6.5 and 8.5.
The requirements for the operation system of the electric pump are shown in
the following figure 2 :
Medium and ambient temperature
The system temperature (t1) must be always higher than the ambient temperature
(t2) in order to avoid an electrical short circuit of the junction box caused
by condensation of the pump body(see figure 3).
Installation tips
- Before installing the pump, check whether the pipeline system is connected reliably and ensure that impurities, welding slag, dirt, and the like in the pipeline have been removed. The output of the voltage adapter is a low-voltage DC 24V. During installation, a filtering screen can be installed at the inlet of the recirculating pump to filter large particles and impurities in the water, and the filter screen shall be cleaned regularly. It depends on the pipe water situation. You can choose to install or not. If the water in the pipe is always clean, you don’t need to install this screen.
- The HIP24-12B pump must be installed or maintained by a professional plumber. Install the pump according to the installation diagram of the HIP24-12B pump. Pay attention to the water pipe connection between the water inlet and the water outlet. After installation, check the HIP24-12B pump and all water pipe fittings for water leakage (seepage). The 、 HIP24-12B pump shall be prevented from being splashed by water to avoid electric shock.
- After connecting the power adapter, conduct a test run of the recirculating pump to check whether the startup is normal, but the nonwater running time should not exceed 5 seconds to prevent the operation from reducing the bearing life.
- When the HIP24-12B pump works, if you want to adjust the position of or touch the recirculating pump, the power supply must be the first cut-off to prevent accidents.
- Carry out regular inspection and make replacements in time when damage occurs.
- If the HIP24-12B pump is not used for a long time or no one is at home, please close the water pipe valve at the inlet and outlet end and cut off the power supply of the recirculating pump.
- The cable or power adapter, when damaged, must be replaced.
- In winter, when the ambient temperature is lower than 0°C, if the electric pump stops running, the water in the pipeline system must be drained to prevent the pump from freezing and cracking.
Installation steps
-
For Electric Water Heater: Turn off Power to your Water Heater. (turn off power at breaker box). For Gas Water
Heater: Turn off the gas to your water heater and ensure that the pilot light is not burning. Shut off the supply water valve to the water heater. In most cases, the supply water valve is located above the hot water heater on the cold water inlet to the hot water heater. -
Shut off the supply water valve to the water heater. In most cases, the supply water valve is located above the hot water heater on the cold water inlet to the hot water heater.
-
Drain the water from the pipe by opening the water faucet in the house. Let the water run until it stops flowing. Leave the faucet open until the pump installation is complete.
If water does not stop flowing, check to make sure the water to the hot water heater has been completely shut off. -
Disconnect the hot water line to the faucet with the hot water angel valve Connect the brass Tee to the 1/2” NPT inlet of the pump. Please make sure the rubber gasket is in the brass Tee. Connect this faucet hot water line to this brass tee and then connect one 1/2 inch supply line (which was provided in the package) to this brass Tee. After that connect this 1/2 inch supply line to the hot water angel valve.
-
Disconnect the cold water line to the faucet with the cold water angle valve. Connect the brass Tee to the 1/2” NPT outlet of the pump. Please make sure the rubber gasket is in the brass Tee. Connect the faucet cold water pipe to this brass tee and then connect one 1/2 inch supply line (which was provided in the package) to this brass Tee. After that connect this 1/2 inch supply line to the cold water angle valve.
-
Use pipe dope or Teflon tape to seal threads when connecting to a 1/2 female NPT connection. If a gasket flexible copper water heater connector is used pipe dope or Teflon tape is not required.
-
Ensuring that the pump shaft is horizontal.
7.2 (optional)Find a suitable installation position (on the backwater pipe near the water heater end). When installing the water pump support plate in advance, the support plate can be placed in the pre-installation position and marked with a marker at the installation hole. The drilling size is φ6.
7.3 Insert
the plastic expansion screw into the hole drilled in the wall.
7.4 Fix the support plate on the wall with self-tapping screws.
7.5 Clip the pump onto the hook of the support plate indicated by the arrow.
-
Reopen the supply valve to the hot water heater and allow the water to run until all the air has been purged from the piping.
-
Close faucet inside the house.
-
Plug the line cord of the pump into a 115V outlet. Be sure to route the power cord so that it does not touch the exhaust vent piping of a gas or oil-fired hot water heater.
**** Key points of installation: remember to open the valve of the cold water
pipe/hot water pipe/return pipe after installation.
DO NOT Mount Motor Shaft in Vertical Position
